All pilots have checklists for every aspect of flying. They always use their checklists even if they only have two steps on them. They do this simply because a checklist is a great way to not forget important steps. It is also how you can assure a predictable outcome.

That is why Aurora and Naperville automotive service centers have procedural standards for each service they perform. Technicians are trained step by step. And they perform the procedures step by step, the same way each time. By training to procedural standards, centers can assure a quality outcome. The job is done right every time and you are happy with how your car performs.

Each company trains its technicians to standards. The industry as a whole is very committed to standards of excellence and encourages individual service center operators to apply them to every vehicle they service.

An example is how service technicians grade problems and communicate their recommendations. If a technician tells you that a repair or replacement is required it must meet the following criteria:

1. The part no longer performs its intended purpose
2. The part does not meet a design specification
3. The part is missing

The technician may suggest repair or replacement if:

1. The part is close to the end of its useful life – just above discard specifications or likely to fail soon
2. To address a customer need or request – like for better ride or increased performance
3. To comply with maintenance recommended by the vehicle’s manufacturer
4. Based on the technician’s informed experience

Here are some examples:

An exhaust pipe has rusted through and is leaking. Replacement is required because the part has failed. If the pipe were rusted, corroded or weak, but not leaking, the technician may suggest it be replaced because it is near the end of its useful life and replacing it now may be more convenient for the customer.

Suppose a customer wants to improve his car’s handling, but his shocks haven’t failed. The technician may suggest replacement of the shocks to satisfy the customer’s wishes.

Under these guidelines the service center must refuse partial service of a required repair if the repair creates or continues an unsafe condition. Let’s say a customer has a cracked brake rotor. This is a dangerous condition that must be repaired. If the customer does not want to replace the rotor, but instead just wants new brake pads installed, the shop must ethically refuse the partial repair. That can be an upsetting conversation, but understanding that service centers operate under service standards and procedures is comforting. You want your service to be done right and to have confidence in your technician’s recommendations.

The automotive service industry and Sterling Automotive Repair want the best for you and for you to keep coming back. AutoNetTV is committed to providing automotive maintenance information to help you be confident in your service decisions.

Nowadays, everyone in Aurora, Illinois is paying more at the gas pump. For some families in the greater Naperville area, it adds up to several hundred dollars every month. That’s got to come out of the budget somewhere. Throughout North America, people are putting off buying a new car. They plan on keeping their old vehicle for a year or two longer than before.

Even now, 2/3 of the personal vehicles on our local Aurora, Illinois roads have over 75,000 miles on them. The average age of vehicles is over nine years. And most people in Naperville can’t afford to be stranded or inconvenienced by a break down. So following a regular maintenance schedule, like our personal diet and exercise plans, is actually critical to preserving your investment.

Knowing what to do for a higher-mileage vehicle can be challenging because many owners’ manuals don’t publish service intervals after 60,000 miles. It just means that you need to be better at keeping records and planning your preventive maintenance.

You can start by figuring that services with a recommended interval should still be performed on that interval, even after you’re past the tables in your service manual. For example, a service might be recommended every 15,000 miles. Well, just keep doing it every 15,000 miles for as long as you have your car.

Now higher mileage engines operate under more stress. Some experts suggest that the severe service schedule is more appropriate and that routine service should be performed at shorter intervals. Check with your owners’ manual or service advisor at Sterling Automotive Repair to see if the severe service schedule is right for your vehicle.

And keeping up with your full-service oil change schedule is important for a couple of reasons. First, older engines have had more time to build up oil sludge. Skipping an oil change here and there can really compound the problem for your sedan.

The second benefit is that your other fluids are routinely checked and topped off. Power steering fluid, brake fluid, coolant and transmission fluid can be kept at optimal levels even though the older seals and gaskets are leaking more than when they were new.

And speaking of older seals and gaskets: they start to dry-out and become more brittle with age. You may want to consider using high mileage formulation oil and fluids. These products contain special additives to condition seals and gaskets to keep them from leaking. The high mileage formulations cost more than standard products, but they are well worth it in terms of preventing serious repair bills down the road.

Older vehicles in the Aurora, Illinois area need repairs and replacements that newer ones don’t. Things like timing belts, radiator hoses, suspension work, anti-lock brakes, air bags, water pumps, alternators and batteries. That may seem like a lot of stuff to have done, but it works out to be cheaper than new car payments.

With a high-mileage vehicle, a couple of relationships will become pretty important. The first is with your service advisor at Sterling Automotive Repair. You need someone you trust to take care of your car and be mindful of your needs. Ask for help to develop a plan to keep your vehicle road-worthy that works within your budget, and for the Aurora, Illinois area driving conditions.

The next relationship is with your vehicle itself. We’re not talking about naming your car or tucking it in at night. We just mean – pay attention and get to know your vehicle. Notice unusual sounds, smells, vibrations, etc. Then you can describe the changes to your service advisor at Sterling Automotive Repair and head off problems. We can’t do anything about the price of gas, but we can properly maintain Old Faithful to keep it safely and economically on the local Aurora, Illinois roads.

The government mandates a lot of equipment on cars for the Aurora Illinois area: emission devices and control computers; safety equipment like airbags; and crash worthiness requirements. All of this is great for the motoring public in Aurora Illinois, but it does add quite a bit to the price of a new car.

Because new cars are more expensive, people are driving their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today’s cars are up to the challenge – but they need a little help to keep on going.

Some owner’s manuals don’t specify service requirements at higher mileage. That doesn’t mean it doesn’t have to be done. In fact, it’s more important than ever to stay on top of routine maintenance for cars with more than 120,000 miles/190,000 kilometers. Just extend regular service intervals out: for instance a service that’s recommended every 24,000 miles/38,000 kilometers should be performed at 24,000 mi/38,000 km; 48,000 mi/77,000 km; 72,000mi/116,000 km, 96,000 mi/154,000 km; and on and on.

Because of the additional stress older engines experience, the severe service maintenance schedule may be more appropriate than the regular schedule. Watch for leaks – seals and gaskets dry out over time and do not hold the fluids as well as they used to. It is also time to make sure you have a good technician. There are some services and replacements that are scheduled after you put some clicks on the odometer, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course.

Check for unusual sounds, smells or the way your car feels. These could be hints that trouble is brewing. Better to catch it early before it turns into a costly repair. Regular wash and wax will help maintain your car’s appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a higher mileage.

High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older engines are dirtier inside – and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection. Come into Sterling Automotive Repair for a checkup.

Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high kilometer vehicles. So once you hit around 50,000 mi/80,000 km, consider stepping up to high mileage formulations. The fluids cost a bit more than standard fluids because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road.

It does cost more to properly maintain a higher mileage vehicle – but it’s much cheaper than a new car payment!

So you love our job, and your family life is great: You have achieved balance. But can you the same for your wheels? You can tell if your tires are out of balance by vibrations at higher speeds. If one of the front tires is out, you feel the vibration in the steering wheel. If it’s a back tire, you’ll feel the vibration in your seat.

Tires and wheels are pretty heavy. When a tire is mounted on a wheel, it is usually not perfectly balanced. So the tire technician will spin the tire on a machine to determine where it’s too heavy. He will then place weights on the wheels in strategic locations to balance it out. When a tire is out of balance, it actually bounces down the road instead of rolling smoothly. Since the average size tire rotates at about 850 revolutions per minute at 60 MPH, it is actually slamming into the pavement 14 times a second. That’s where you get your vibration.

Most people are surprised at how smoothly their car rides after balancing all four wheels.

Most high-quality tires hold their balance pretty well. They just get out of balance gradually with normal wear and tear. If you suddenly feel a vibration, it is probably because you lost a wheel balancing weight along the way. Definitely get a balance if you feel a vibration, change your rims or have a flat repaired. Putting off a needed balance job leads to excessive tire wear, wear to your shocks, struts, steering and suspension parts. wheel balancing not only improves your ride and handling, but also can save you some big repair bills and possibly an accident. Additionally, you will get better gas mileage.

Some people have their tires balanced at every rotation. Others do it every other time. Check your owners’ manual for your requirements, or ask your technician. Doing thus will put you on the path to mechanical wheel balance

Everyone in Aurora Illinois knows we’re supposed to go to the dentist twice a year. We get our teeth cleaned and have a thorough dental inspection. Once a year, we get x-rays to look for problems that can’t be seen with the naked eye. When the dentist is done, he tells us what he’s found – “Everything’s fine, see you in six months.” Or “You’ve got a small cavity starting, let’s schedule an appointment to take care of it.” By the time you leave, you have a plan for addressing any necessary repairs.

This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.

If we buy into this way of handling our dental care, why do we resist so much when facing the same system for our car care?

Following the manufacturer’s recommended intervals can be confusing. First there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing …you get the point.

Every item has a recommended interval and it’s hard to keep it all straight – even if you’re part of the 1% of the population that reads your owners’ manual in Aurora Illinois.

And if you have more than one car or sedan, the complexity is multiplied. You’d need a computer to keep track of everything. Well, that’s how your Aurora service center does it. They subscribe to automotive databases that have your vehicle’s recommended intervals. You may have wondered how they know what else to recommend when you take your car in for an oil change – it’s all in the computer.

Well, it’s not all in the computer. There are other variables that can’t be accounted for in the schedule. Things like the weather conditions, altitude, and where and how you drive when you are out in our Aurora Illinois area need to be taken into account. Talk about these things with your service advisor at Sterling Automotive Repair and you may decide that the severe service schedule in your owner’s manual is more appropriate.

Since anything that’s not highway driving in moderate weather is considered severe, most of us do at least some of that around Aurora Illinois and it should be taken into consideration.

Let’s take your basic oil change as an example – what issues are involved? The oil you put in your car is a blend of base oil and special additives. There are detergents to clean the inside of your engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.

Now, these additives deplete with use and time. That’s why most maintenance recommendations include both a time and mileage element – like 3 months or 3,000 miles, whichever comes first.

It’s easy to think, “Gee, I’ve only driven 2,000 miles in the last 3 months. I can wait on that oil change.” But you need to remember that the inside of your engine is a harsh environment. The oil is contaminated with combustion by-products that starts degrading its effectiveness even when it’s just sitting there.

A lot of people in Aurora Illinois don’t realize the harm that can be done by just skipping a single oil change. There are a lot of metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it’s clogged up because you haven’t changed it, it can’t trap any more.

Oil sludge is another problem. Sludge is oil that has turned to a gunky jelly – think ‘Vaseline’. Obviously, sludge doesn’t lubricate. It can also clog small oil passages so that all the parts don’t get properly protected by the oil. That’ll lead to premature wear.

If you’ve missed some oil changes, don’t despair. Just talk with your service advisor at Sterling Automotive Repair. Fess up – you’ll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your car on the road and avoiding major repairs in Aurora Illinois.

Take a look at the auto tips video in this post for more information.

We find that a lot of Aurora service and repair at Sterling Automotive Repair are a little tentative when they talk with their automotive advisors. They want to ask questions, but don’t want to be embarrassed or to seem pushy. Cars are very complicated and there’s more to know about them than most of us have the time to learn. Maybe it’s because cars have become so much more reliable that the average person just doesn’t need to know as much to keep their vehicle on the road.

You know, your local hospital has a Patient’s Bill of Rights that they post throughout the hospital. We think our Aurora automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.

It’s all about the communication. It’s a little harder when you’re trying to find the right service center in Aurora. But once you’ve developed a relationship, the communication should come easier.

What are some of the barriers to communication? Well, let’s go back to the medical example. When your doctor’s explaining something to you, it’s something that she understands very well and is very familiar with. So she may use jargon you don’t understand or that you don’t have the education and training that’s foundational to understanding what she’s trying to explain.

So you fall behind and get frustrated.

It can be the same with your Aurora automotive service advisors. Most of them are very busy trying to service and fix cars to get their customers back on the road. So, just ask when you feel you need more information.

Financial related issues seem to be most frustrating to customers. If you’re not sure, ask what the payment policies are. For example, there’s a big difference between giving your car a quick once over and doing a thorough inspection. Diagnosing a problem may take quite a while. Make sure you know what’s done as a courtesy and what has a fee. Remember, you still have to pay for the office visit even if the doctor says you only have a cold.

Communication is a two way street. If you have some real budget concerns, ask your Aurora service advisor what he can do. He can give you priorities and options. He can tell you what needs to be taken care of right away for safety or financial reasons. Then you can work out a plan for when to get the rest done. He can also help you with options on the parts. The preference is to always use a high-quality part with a reputation for reliability. But if money is real tight, he might be able to find a rebuilt part or a used part. He should tell you the difference in the guarantee for the part so you can make a good decision.

Ask about warranties for parts and labor. Be sure to get all the paperwork you need to make a possible claim in the future. Your service center and its technicians stand behind their work and want you to understand precisely what that means.

Be sure to ask for and keep a detailed explanation of all the work that’s done on your vehicle. These records will help you keep track of service, warranties and document the good care your vehicle has received when the time comes to sell it.

Did you know that most of the cars driving around Aurora Illinois carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Naperville area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle’s functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do you know when there is a problem?

It’s simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to our service center at Sterling Automotive Repair to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your technician at Sterling Automotive Repair has special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you’re check engine light is on.

Let me start by saying that your wheel bearings keep the wheels on your vehicle. Did that get your attention? In this article we’ll discuss more about wheel bearings and how you can keep them doing their very important job while you drive around Aurora Illinois.

Come see us at: 9 S. Route 59 Aurora, Illinois 60504

Wheel bearings are pretty simple parts. They’re made of high quality steel and are engineered to last 100,000 miles or more if properly cared for. The bearings do two very important jobs: First they allow the wheel to freely rotate with as little friction as possible. Second, they support the weight of the vehicle. For example, if your car weighs 3,600 pounds, each wheel has to support approximately 900 pounds. That’s a lot of heavy lifting over many, many thousands of miles.

Even though wheel bearings are relatively simple, they need to be in near perfect condition to do their job. The bearings are packed with heavy grease to lubricate and protect them. A seal keeps the grease in and water and dirt out. It’s when the seal starts to leak that problems begin. The grease can become contaminated; causing the wheel bearings to overheat and ultimately fail.

The first sign that your wheel bearings are in trouble is an unusual noise coming from a wheel. It could be a chirping, growling, rumbling or a cyclic sound. The noise could get louder or even disappear at certain speeds. Your technician at Sterling Automotive Repair can inspect for bearing wear by lifting the vehicle and checking for play in the wheel.

Now some wheel bearing assemblies are factory sealed. That means that they cannot be serviced – they can only be replaced. Those that aren’t sealed can be serviced on schedule. The bearings are removed, cleaned and inspected. If the bearings are still good, they’re re-installed – if not, they’re replaced. They are then packed in grease and a new seal is installed.

If your vehicle has a factory sealed wheel bearing assembly, the entire assembly needs to be replaced when trouble arises. Unfortunately, the parts are pretty pricy – but they usually last about 150,000 miles as long as the seals hold up.

Now, even a good seal cannot keep out water that’s exerting pressure on the seal. So if you’ve driven through hub deep water your bearings should be cleaned and repacked if they’re serviceable. If you have factory sealed bearings, you just need to watch for signs of premature failure.

If your wheel bearings can be serviced, your owner’s manual will recommend an interval, usually around 30,000 miles.

Now, if you have any sort of trailer, don’t forget its wheel bearings. They probably need to be serviced even more frequently. This is especially true for boat trailers that are used to launch the boat by backing it into the water. These should be serviced every year, usually at the end of the season so that the bearings don’t have the opportunity to sit and rust all winter.

So what happens if wheel bearings fail? Well, the wheel can literally fall off the vehicle. I don’t need to tell you how bad that could be. So check with your service advisor at Sterling Automotive Repair and see if your vehicle’s wheel bearings can be serviced and when it’s recommended. Listen for warning signs. If you’ve been fording streams or puddle surfing after rainstorms, be especially vigilant.

In very simple terms, a fuel injector is a valve that squirts fuel into your sedan engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Aurora, Naperville, and Plainfield roads.

Most fuel injectors for gas engines are known in the Naperville auto industry as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few auto makers have recently introduced gas direct injection systems on some engines. They are now available at some Naperville dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved fuel economy for gas-poor Aurora, Naperville, and Plainfield commuters. Illinois motorists can expect to see more of it in the future.

High temperatures under your sedan hood and variations in Naperville gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel economy and loss of power. So it’s important for Aurora drivers keep their fuel injectors clean.

Your Aurora Sterling Automotive Repair service center can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your sedan fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Naperville repair bills down the road.

So what is the most distracting food to have in the car while driving around Aurora?

Is it:

1. A Hamburger;
2. Coffee;
3. A Soft Drink, or
4. Gummy Bears?

Well, you may be surprised to learn that all but the gummy bears are in the top ten most distracting foods when you are driving, but if you chose ‘coffee’, then give yourself an extra two points; coffee is the number one food distraction for drivers in Aurora and around the country.

Food distractions cause 25 percent of all car accidents; over a million and a half each year!

You’ll notice that all of the top ten distracting food items are messy. Messy foods are the type of food you might spill (very distracting!), then try to clean up (a safe-driving impossibility!). If you gotta eat on the run, take five-then drive. You’ll thank yourself later for two reasons, one being that you can actually relax for just a moment in our fast-paced world, and the other is that you won’t have to worry about getting that cinnamon roll frosting out of your dashboard after that near miss.

Keep drinks in spill-proof containers, too, so you can keep your eyes on the Aurora road without worrying about where that spill is headed.

So; taking a food break… Or filling out accident reports. We don’t have to ask you which you prefer: It’s a no brainer.

Sterling Automotive Repair, along with AutoNetTV, wants you to keep both eyes on the road. Please eat safely and keep your eyes on the road.

When your car breaks down in the Aurora Illinois area, or just needs some routine service, it can make you a little nervous. Because your car’s so important to your life, you need to be back on the road as soon as possible. And, with the problem fixed right the first time.

We’ve been checking into some of the training our Aurora Illinois technicians receive, and we’re very impressed. It’s amazing how much knowledge and skill goes into diagnosing and repairing a modern car. So it’s not like when your uncle worked on his hot rod over weekend.

Today there are four cylinder engines that make more power than the V-8’s in luxury cars 20 years ago. A new V-6 Toyota Camry could beat Sonny Crocket’s Ferrari in a race to 60 mph.

Our engines are more and more powerful and at the same time their fuel economy keeps inching up. And they’re so reliable. This is all due to engineering. But the advances come at the price of simplicity. Modern cars are so much more complex from a mechanical standpoint that it makes your head spin.

Then there’s the electronics. Some cars in the local Aurora Illinois area have several networked computers controlling most of the engine functions and many other vehicle functions as well. We take all of this sophistication for granted – but somebody has to fix it when it breaks.

It’s a real challenge for your local Aurora Illinois technicians to keep up. It requires a high level of commitment on the part of the auto technician and the service center as well. In addition to the training, there’s the financial commitment to purchase the diagnostic and repair tools as well.

So where do Aurora Illinois technicians go for training? There’re many sources. It’s usually a combination of formal classroom training, training provided in the service center by parts and equipment manufacturers, on-line courses and home study courses. There are many independent certifications available all the way up to Master Technician.

And AutoNetTV produces monthly training for service centers called The Pro Channel. If you were to watch the Pro Channel segment on re-flashing the engine control computer, you’d be amazed at how much is involved: special software, hardware interfaces and a tremendous amount of knowledge and skill.

Service centers in Aurora Illinois have a lot of other resources available as well. No one can know everything, so service centers like Sterling Automotive Repair subscribe to data services, technical libraries and even on-line communities that can help them with they run into a difficult problem.

It’s like those medical diagnosis shows on TV. Here are the symptoms – what’s the diagnosis and treatment. Diagnosis is every bit as much an art as a science. As consumers we want everything to be simple, straight forward and cheap – and sometimes it just isn’t.

So, be more relaxed next time you take your car in. You really should trust your service advisor at Sterling Automotive Repair. You’re in good hands. The more you know, the more comfortable you can be with your automotive service decisions. Visit AutoNetTV.com to see more great auto tips videos about many service topics.

Welcome to the Sterling Automotive Repair blog. Today, let’s talk about the effect of tire tread depth on braking. When talking about stopping power, most of us Plainfield drivers tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough. Safe Plainfield drivers need to have tires with enough traction to translate braking power into stopping power.

Let’s focus on stopping in wet Plainfield conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water.

That’s called hydroplaning. If it’s really bad, Plainfield drivers can actually spin out of control. At best, you won’t stop as fast.

So how does a tire move water? It has channels for water to flow through. Look at your sedan tire and you’ll see channels: channels that run around the tire and channels that flow across the tire. They’re designed to direct water away from the tire so it can contact the road better.

And the deeper the channel, the more water it can move. A brand new Sterling Automotive Repair tire has very deep channels and can easily move a lot of water. As the tire wears down, the channels become shallower and can move less water. When it wears down enough, it can seriously affect your ability to stop your sedan on wet Plainfield roads.

So that’s why it’s so important to replace our sedan tires when they get worn. Consumer Reports and other advocate groups call for a standard of 3/32 of an inch and they have the studies to prove it.

By comparison, you’ve probably seen the wear indicator that’s molded into tires. When tires are worn 3/32 of an inch, the tread wear bar is visible. So the recommended standard has twice the tread depth as a completely worn out sedan tire.

At Sterling Automotive Repair, we want our customers to know that the deeper recommended tread depth makes a big difference. Stopping distances are cut dramatically on wet Plainfield roads. A safe stop from Illinois freeway speeds with 4/32 of an inch of tread would result in a crash with worn out tires.

There’s an easy way to tell when a tire’s worn to 4/32 of an inch. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your sedan tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Many Plainfield car owners have heard of this technique using a penny and Abe Lincoln’s head. That measure gives you 2/32 of an inch – half the suggested amount. Of course, sedan tires are a big ticket item. Most of us in Plainfield want to get as many miles out of them as we can. But there’s a real safety trade-off. It’s your choice.

People in Aurora have been hearing a lot about higher oil change intervals these days. Maybe you’re wondering: What are the key issues?

Some new vehicle manufacturers in Aurora are now recommending much higher oil change intervals than they have in the past. As much as 5,000 to 8,000 miles or more. This practice came under scrutiny when four of the largest new car manufacturers announced that owners like those in Aurora were experiencing engine damage resulting from these higher oil change intervals.

The manufacturers’ standard oil drain service for particular vehicles was scheduled at around 7,500 miles. People following these recommendations were experiencing engine damage. It turns out that oil sludge was building up. This caused small oil passages to clog and engine parts to fail.

What causes oil sludge? It’s a factor of time and mileage. There are hot spots in every engine that cause oil burn off that leads to sludge. Also, water from normal condensation can build up in the oil. This water also creates sludge. Severe driving conditions lead to more rapid sludge formation.

Visit Sterling Automotive Repair in Aurora, Illinois 60504

Severe driving around Aurora includes short trips under four miles or trips under ten miles in freezing conditions. The engine just doesn’t get warm enough for the water in the oil to evaporate.

Severe conditions are at the heart of the problem. Stop-and-go driving, towing, dusty conditions, heavy loads, very hot or very cold temperatures, a car top carrier – these are all conditions that would suggest that the severe service schedule should be considered.

The severe service schedule has much shorter oil change intervals. People in Aurora just need to honestly evaluate how they drive to determine if they should change their oil closer to the severe service schedule, or to the standard schedule.

Some types of sedan will give oil change reminders. But it’s important to know how that reminder is determined. For some, the reminder simply comes when the standard mileage interval has rolled around. Others use a computer algorithm that takes into consideration the number of cold starts, trip length, engine temperature and so on. It’s programmed to approximate where on the standard/severe service spectrum you fall. Some more expensive vehicles actually have sensors that test the cleanliness and effectiveness of the oil.

For the rest of us, better safe than sorry should be the guiding principle. Talk with your Aurora service advisor at Sterling Automotive Repair and work it out together. Find out what kind of oil the factory sends out in your vehicle. Sometimes it’s a premium grade that costs more than standard oil – but it may be what’s needed to meet a higher factory recommended interval.

If you’re realistically conservative, standard grades of oil will take care of you year after year. If you want to push the limits, ask for a premium grade oil to give you extra protection.

So, what happened with those manufacturers with the problems from higher oil change intervals? They ended up extending the engine warranty for parts that were affected by oil sludge. But they had a stipulation – they lowered the oil change interval and the vehicle owner had to provide proof of oil changes at the new lower interval to keep the extended warranty.

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine, has to do with the combustion cycle.

Your sedan engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call Sterling Automotive Repair at 630.851.3610 for answers about your timing belt, or drop by our Aurora Illinois service center on 9 S. Route 59, 60504

It’s critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It’s vital and precision work. Timing belts are made of very tough flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bend or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It’s a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it’s at 60,000 miles. For others it’s at 90,000 miles or more. If you’re approaching 60,000 miles, or have passed it, make sure you check your owner’s manual or with your Aurora Illinois auto service advisor at Sterling Automotive Repair for when the timing belt should be replaced. Don’t let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Sterling Automotive Repair for an inspection right away if you have a coolant leak.

Most people in the Naperville area with this engine design end up with a new timing belt when they replace the water pump. And when you’re having your timing belt replaced on schedule, check with your Aurora Illinois auto service advisor at Sterling Automotive Repair to see if it makes sense to install a new water pump, even if it isn’t currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don’t need to be replaced like belts.

We’ve already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Sterling Automotive Repair in Aurora Illinois so you can begin to prepare for the expense.

Today we’re talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.

A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they’ve had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That’s the fuel filter’s job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner’s manual or ask your service advisor if your fuel filter is due for replacement.

The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.

It’s real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can’t do that if they’re dirty. Dirty fuel injectors really rob power and waste fuel.

It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it’s burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it’s dirty.

The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it’s dirty as well.

Do all these things and your engine’s air and fuel will be as clean as possible. You’ll get much better fuel economy and better power

.

Is your car sometimes hard to start on an early Aurora morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your car’s fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.

Most of our sedan in Aurora have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner’s manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.

Some people are interested in buying fuel system cleaners that you can pour into your gas tank. You can do that – and there are lots of great products available that can help maintain an already clean fuel system – but these products cannot do a major cleaning. For that, you need to see your service center at Sterling Automotive Repair. Sterling Automotive Repair has the professional tools and chemicals to really do a complete service.

Your service center at Sterling Automotive Repair in Aurora Illinois uses a process that gives your car a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you’ll notice more power, better fuel economy and reduced exhaust emissions.

The cleaners also help prevent rust and corrosion in your fuel system and lubricate vital engine parts.

Fuel system cleaning is just one of those recommended service items that helps keep your vehicle running strong. As with all maintenance, it can help avoid costly repairs that often result from not taking the right preventive steps. And you will notice the difference in how well your car runs. Check with your service advisor at Sterling Automotive Repair in Aurora Illinois to see when your car is scheduled for a fuel system cleaning.

An ounce of prevention really is worth a pound of cure.

At AutoNetTV we love doughnuts. So let’s pretend you have three doughnuts right in front of your for our discussion of upsizing wheels and tires. Hey, don’t eat them now – your going to need them later.

Many people want to accessorize their car – you know, make it theirs. One of the easiest ways to get a custom look is to get some new wheels. There are thousands of wheel designs out there to get you the look you want. And for many, that look includes bigger wheels. It used to be that cars came from the factory with 15 or 16 inch wheels. Now 16, 17 and even 18 inchers are standard. And the factories are offering optional wheel packages up to 20 inches or more.

Come in to Sterling Automotive Repair to learn more about how you might upsize your wheels or tires.
You’ll find us at 9 S. Route 59 in Aurora, Illinois 60504.

So let’s talk about what to consider when you want to upsize your wheels. It’s not exactly a do it yourself project, so you need to know a thing or two before you get started. The most important term to know is rolling diameter. The rolling diameter is simply the overall height of your tire. Unless you want to modify your suspension, you’ll want to keep your rolling diameter the same when you upsize your wheels.

Let’s think about those three golden doughnuts in front of you. They’re all about the same size. So if we pretend they’re tires, they would have the same rolling diameter. The doughnut hole is the size of the wheel. Now pretend we’ve made the hole bigger on some. That’s like having a bigger wheel – but the rolling diameter is the same.

It’s important to keep the rolling diameter the same for several reasons. First of all, if the tire is bigger, it might not fit in the wheel well. Next the speedometer, odometer and anti-lock brake system are all calibrated for the factory rolling diameter. In order for your anti-lock brakes to work properly, the rolling diameter must stay within 3% of the factory recommendation. If you ignore that, you run the risk that your anti-lock brakes won’t work properly.

Some cars today have electronically controlled suspension that will be negatively affected by changing the rolling diameter. Let’s think about the doughnuts again. You see, as the size of the wheel gets bigger, the sidewall gets shorter. The tire holds less air, so the sidewalls are made stiffer to compensate.

Low profile tires from top manufacturers use special compounds that give the sidewall the strength it needs without compromising ride quality. As you increase your wheel size, you’ll typically get a slightly wider tire. This means that you have a larger contact patch. The contact patch is part of the tire that contacts the road. Because there’s more rubber on the road, the vehicle will handle better. And braking distances will be shorter. A lot of people with trucks or SUV’s love the extra control.

You do have to watch out that the contact patch isn’t so big that the tires rub in turns or over bumps. What we’re talking about here is fitment. Your tire professional at Sterling Automotive Repair can help you get this right. He’ll install your new wheels, add spacers if needed to make sure your brakes fit inside your new wheels, and get you rolling.

Also, if you drive off-road a lot, you may need a higher profile tire to protect your new rims. And make sure your new tires have the load rating you need if you tow a trailer or haul heavy loads. Again, your tire professional at Sterling Automotive Repair knows how to help.

And don’t forget about tire pressure. If you have larger rims, your new tires will hold less air and they’ll need to run a slightly higher pressure. Forget that and you’ll wear your tires out fast. Finally, get an alignment after you get your new shoes. AutoNetTV wants you to safely have the look you want.

If you’re like most of us in Aurora, you want your car to handle well. That’s the job of your suspension system.

There are different types of suspension systems, but they all work on the same basic principles. First, there are the springs, which bear the weight of the car. The most common springs are coil or leaf – although we see air springs and torsion bars more often. The springs do most of the work.

Visit our Aurora location for an inspection of your suspension.

But if all you had were springs, your vehicle would be bouncing around like a bobble head. That’s where the shocks come in. They control the rebound of the springs and smooth out the up and down motions. They also keep the tires on the road, and you in control. Some sedans use struts. Struts are a combination of shocks and springs, together in a more compact system.

Shocks wear out slowly over time, so it’s hard to notice when they get badly worn. One way to tell is to look for an uneven, cupping wear on your tires. If the shock or strut is leaking fluid, it needs to be replaced. If your car feels floaty in turns or if the front end dips a lot when you stop, it is time to get your shocks checked. Your owners’ manual will tell you when your shocks should be changed – it’s usually between 15,000 and 30,000 miles or 24,000 and 50,000 kilometers .

When you replace a shock, be sure to replace all four. Then your car will have an even suspension and will handle much better. Talk with your service advisor about how you drive. No, not your traffic violations, but how often you carry heavy loads, tow a trailer or drive in rough terrain. If you do a bunch of that, you’ll need a heavy duty shock.

Regular shocks use hydraulic fluid and air as their dampening system. Premium quality shocks and struts use compressed nitrogen gas instead of air. Gas shocks don’t get air bubbles that affect the performance of regular shocks. If you do a lot of high performance driving, off-roading or just want added comfort and control, think about getting premium gas shocks or struts.

Replacing your struts may take your car out of alignment, so be sure to get an alignment at the same time. So, to smooth out the bumps on the road of life, change your shocks and struts when they need it.

Sometimes it seems in Aurora we live in such a disposable society. It’s amazing all the stuff we throw away.

New stuff comes out so fast, we just toss the old and move on. It seems like when we were kids in Aurora, our parents were real sticklers about taking care of our stuff. You know, hang up your clothes, polish your shoes, put away your toys. If something got lost or ruined by neglect, tough, we had to do without.

We couldn’t afford new cars very often, so we tried to make them last as long as we could. It’s a good thing that cars are more reliable these days. They just don’t break down as often. And the good news for us Aurora penny pinchers is that a modern car can easily go 200,000 miles with proper care. The engineering’s there and so is the manufacturing quality. The missing ingredient is us making sure we follow the manufacturer’s recommended maintenance schedules.

Is it really that bad to get off schedule? Well, it all adds up. Every time you go a couple thousand extra miles between oil changes, you’ve created an opportunity for sludge to form and clog passages. Then some parts don’t get oiled and they start to wear out faster.

Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. The same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.

It’s also even more important for older vehicles in the Aurora area. Those engines and other systems have had more time to get dirty, so they’re a bit more stressed anyway. But it’s never too late to get back on track with your maintenance and to hold off further damage.

It’s just another example of our parents being right. (Surprising how often that happens.) And it really does start with the oil change, just like Dad said. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. That’s like your safety net; go in for oil changes on time, and let your service advisor at Sterling Automotive Repair in Aurora help you keep track of the rest.

Of course, some things are going to wear out along the way, stuff like alternators, water pumps and such. But that stuff is cheaper than a new car payment. And taking care of problems early means they have less time to cause other problems. It’s like having high cholesterol; you don’t want to wait for a heart attack before you address it.

One Aurora automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Aurora, but they’re very important. First let’s define what the driveline is:

Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.

That’s not really a lot of components, but they handle the full force of the engine. Without the driveline you’re not moving. So we need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we’re going to have to over simplify a bit.

If you are ready to have your drive train looked at, give us a call:

Let’s start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel, come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.

So, driveline service would include properly servicing the transaxle and inspecting the CV boot to see if it’s torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner’s manual or check with your Aurora service advisor.

On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Aurora have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. You’ve probably heard the term ‘u-joints‘. These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected.

The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axle is damaged or leaks, the axle will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Aurora service advisor for intervals.

Now let’s go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The vehicle may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.

Some all wheel drive vehicles are designed to work well off-road, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don’t work well on dry pavement when they’re in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.

Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is required as well as service to the center and rear differentials.

Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There’s a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So you need differential service for the front and rear differentials and for the transfer case as well.

The bottom line is that the maintenance schedules are in your owner’s manual. Your Aurora service advisor can answer any questions you’ve got. If this is the first time you’ve heard some of this stuff – it’s time to ask someone at Sterling Automotive Repair if any of it needs to be done now.
