Coolant/Antifreeze Service at TJ's Auto Center Inc.

Anyone who drives a car in Rockford knows that engines get hot when they run. But did you know that engines need to be cooled to keep running? Heat inside an engine can cause the metal parts to expand, which can seize up an engine and make it stop running. It can even ruin the entire engine! Good vehicle care requires keeping its cooling system in good condition.

A vehicle's cooling system circulates water and antifreeze (coolant) through the engine where it absorbs heat. It then flows to the radiator where the water and antifreeze are cooled by the air that flows over the radiator. Then it circulates back into the vehicle's engine to absorb more heat.

Why shouldn't Rockford auto owners just use water? Because water boils at temperatures that are often reached inside of an engine. Steam won't cool your vehicle engine and is hard to contain within the cooling system. The antifreeze keeps the water from boiling.

So why do we call it antifreeze? Shouldn't it be antiboil? Truth is, the antifreeze performs another critical task. Water freezes in cold Illinois weather. That would spell disaster for your vehicle's engine. So antifreeze also keeps the water in your cooling system from freezing in all but the most extreme cold. Pretty neat stuff!

Taking care of your cooling system is part of good preventive maintenance for your vehicle. Rockford area drivers should check coolant level often and regularly inspect your cooling system for leaks.

That is just good auto advice. Your vehicle's manufacturer has maintenance requirements for draining and replacing engine coolant. Consult your owner's manual or ask your friendly and knowledgeable TJ's Auto Center Inc. service advisor for these recommendations, as they vary widely among vehicles.

Line ?Em Up: Wheel Alignment Service At TJ's Auto Center

Hello Rockford motorists! Let's talk about alignment. One of the most important parts of preventive maintenance for your vehicle is keeping the wheels in alignment. Poor alignment causes your tires to wear unevenly, which can significantly reduce their lifespan. This means you will have to replace them more often, which can be costly in Rockford.

It can even damage your suspension system, which is an expensive repair. But even more importantly, uneven tread wear can lead to blowouts on the road, a dangerous and potentially deadly safety risk for Rockford drivers and their passengers.

It may not take an accident or bad driving habits to “knock” your tires out of alignment. Tires can go out of alignment with just everyday Illinois driving. Rockford road hazards, pot holes, uneven or gravel roads, even the bumps and bounces of normal Rockford, IL expressways and surface streets can gradually put your sedan tires out of alignment.

So it’s good auto advice to have your sedan's alignment inspected periodically. Your vehicle’s owner’s manual will have recommendations on how often you should get an alignment check: usually every year or two. But if you think your sedan tires might be out of alignment, you should take your sedan into TJ's Auto Center now.

When you take your sedan in for an alignment in Rockford, your Friendly and professional TJ's Auto Center service advisor will start by inspecting the steering and suspension systems. If something is broken or damaged there, it will need to be repaired in order to get good alignment of the wheels.

If all looks good in the steering and suspension departments, the sedan will then be put on an alignment rack where an initial alignment reading is taken. The wheels can then be aligned to the auto maker’s specifications. The ideal alignment for any vehicle is set by its engineers and may vary from vehicle to vehicle.

There are three types of essential adjustments that may have to be made to correctly align a vehicle’s tires. The first is called “toe.” This refers to tires that are out of alignment because they point inward or outward at the front of the tire. Think of a person who is pigeon-toed or splay-footed, and you get the idea.

The second adjustment is the camber. This adjustment affects the angle at which the tires meet the road. Think of a solid building in contrast to the Leaning Tower of Pisa.

The last adjustment is the castor. This adjustment measures the angle of the tire in relation to the front axles. So, a piece of auto advice that just might be good for life as well: keep everything in alignment, and you’ll be able to steer where you want to go in Rockford, IL. Drive safely.

What Is That? Check Engine Light Service at TJ's Auto Center Inc.

Okay. You went to your local Rockford car wash, and while your vehicle was under the dryer, the Check Engine light started flashing. Panic! What did you just do? Something is seriously wrong with the vehicle! You head for the nearest Rockford service center, but on the way, the Check Engine light stops flashing and just glows red. Hmm. Maybe things aren't as bad as they seem. You decide to wait until payday to take your vehicle in to get serviced. In the meantime, the Check Engine light goes off. What? You decide the light must be faulty; maybe when it comes on it doesn't mean anything, or maybe it's just in your vehicle as some sort of scam to get you to pay for unnecessary repairs. You're glad you didn't take your car to the Rockford repair shop and resolve to ignore that Check Engine light in the future.

Whoa! Let's look at what really happened. Your vehicle was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered; there shouldn't be that much airflow when the vehicle engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The Check Engine light starts flashing, letting you know you need to take immediate action to prevent that damage.

You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the Check Engine light to stop flashing. The vehicle doesn't need immediate attention; but there was a problem, and it should be checked out by your TJ's Auto Center Inc. service advisor. After a few days the computer senses that the problem is gone, so it turns off the warning light.

You may think this story illustrates the uselessness of a Check Engine light, but you should remember that a computer can't think for itself; it can only follow its programming. It doesn't know the difference between a car wash air dryer and a serious malfunction in your vehicle engine. That doesn't make it useless. It just means you have to be the smart one.

Being smart doesn't mean ignoring your vehicle Check Engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.

Your engine computer is constantly collecting data about what is going on inside your vehicle engine. It knows what parameters are normal and when a reading may indicate a problem. It uses the Check Engine light to let you know when something isn't right. It then stores a code in its memory — which a technician can retrieve — that indicates which reading was abnormal.

The technician uses this code as a starting place to find out what's wrong with your vehicle. It's like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what's causing it. It's probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what's NOT wrong with you. Fevers don't accompany stress headaches, ulcers or arthritis, so there's no sense in testing for those conditions.

The pros at TJ's Auto Center Inc. respond to a trouble code in your vehicle's computer in the same way. The code doesn't say exactly what's wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn't need to look.

Now, you wouldn't consider diagnosing yourself with a serious medical problem — good medical advice unless you're a doctor. So you shouldn't consider trying to diagnose your vehicle's troubles by yourself — good auto advice unless you're a trained mechanic.

There are cheap scanners available on the market, and some Rockford auto parts stores offer to read trouble codes from your vehicle engine's  computer for you. But these are really not good alternatives to taking your vehicle to a qualified service center such as TJ's Auto Center Inc. in Rockford. Your engine's computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can't read an engine computer's long-term memory nor can they interpret manufacturer-specific codes. That's why our manager at TJ's Auto Center Inc. spends a lot of money on high-end diagnostic tools.

It's as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?

Getting your codes read at your Rockford area auto parts store isn't really a money-saver, either, unless you're a trained mechanic. You'll end up with a code that tells you a symptom. What usually happens next is that the Rockford area parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It's actually cheaper to just go to TJ's Auto Center Inc. and get things fixed right the first time.

Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it likely won't help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?

Part of good vehicle care is knowing where you can get a problem fixed — and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let's do it right the first time at TJ's Auto Center Inc..

Talk to TJ's Auto Center Inc. About New Shoes for Your Vehicle

Custom wheels are one way that Rockford folks express themselves and personalize their vehicle. But they aren't as cheap and easy as sticking decals on your back window. There are several factors that need to be considered, including cost, the fit of the wheel, modifications that will have to be made to the vehicle, how the new wheels and tires will affect the operation of the vehicle, your driving habits and, of course, the style of the wheels. Most Rockford drivers start with the last factor: the style of the wheels. But that should be the last thing we choose.

When considering custom wheels, you should first carefully consider your budget. Some wheels may require adjustments to your vehicle suspension system, brakes, or traction systems. You need to know what you can afford before you start shopping or get your heart set on a particular type of wheel.

There are three basic ways you can change your wheels. First, you choose a wheel that is already the same size as the ones on your vehicle. Second, you can choose larger wheels and third, you can choose smaller wheels. Mounting wheels that are the same size as the ones already on your car sounds easy enough. But even though the wheel may be the same diameter as your current wheels, that doesn't mean it will fit your vehicle. Besides diameter, wheels also have an offset. This is the measurement from the inside edge of the wheel to the point at which it bolts on. If your new wheel does not have the same offset as your current wheels, your vehicle tires can rub on the inside or outside of the wheel well. This can lead to blowouts, uneven tread wear and other mechanical problems.

The tire and wheel professionals in Rockford at TJ's Auto Center Inc. on 3427 E. State St. can help you select a wheel that has both the correct diameter and offset for your vehicle. Or, if you really want a specific wheel in spite of the offset difference, your technician may be able to install adapters that will make the wheels fit.

Mounting larger wheels is a more involved process. There are several ways of doing this. You can mount larger wheels but keep the overall tire diameter the same. Or you can “supersize” your tire/wheel combo. Mounting larger wheels while maintaining the same overall tire diameter is the easiest way to increase wheel size. You still need to adjust for offset. Generally, this alteration means that your new tires will be wider than the originals, so you will have to install adapters to keep them from rubbing on the wheel wells. Consult your service advisor at TJ's Auto Center Inc. by calling 815-399-2886.

If you want to install larger wheels and increase the overall tire diameter, it is important that the package fits in the wheel well; you may have to do some minor modifications to your suspension. More importantly, you will have to reprogram your vehicle engine's computer to calibrate for the larger tire size. The computer calculates your speed based on the rotation of your tires, so increasing the size of the tires will render it inaccurate. Inaccurate speed calculations can mess up your anti-lock brakes and your stability control systems, as well as your speedometer and odometer.

As you can see, the more modifications you make, the more it becomes important to have your friendly and knowledgeable TJ's Auto Center Inc. tire and wheel professional help you with your car care.

If you really want those “super-sized” tires, great: just factor in the issues listed above, plus you may have to have modifications done to your suspension system.

The larger wheels and tires will add weight to your vehicle. This weight is not held up by the suspension system, so is referred to as “unsprung” weight. Adding unsprung weight affects your car differently than just adding loads inside of your car. Unsprung weight can affect acceleration and braking. Putting large wheels on your vehicle may require an upgraded brake system.

Also, you may not get the performance from your vehicle that you've been used to. It may be sluggish when accelerating or harder to handle when turning. You may also find that the ride is bumpier than it was before. Of course, done right at TJ's Auto Center Inc., a good wheel job can sometimes improve a vehicle's ride or performance. It just depends on your vehicle, the type of wheels you choose and what you are hoping to accomplish.

Now let's suppose you want smaller wheels on your vehicle. That should be easier, right? Not really. You still have to worry about offset, and it is important that your computer be reprogrammed to account for calibration issues. And you may need adjustments to your suspension system.

Remember your budget? All of these scenarios require that you shell out some money. Perhaps now you can see why it is good auto advice for Rockford drivers to make that consideration first, before setting their heart on a specific type of wheel.

Another consideration should always be your driving habits. Do you do a lot of off-roading on the outskirts of Rockford? Do you carry heavy loads? Do you tow a trailer on Illinois roads? All of these factors must be considered when replacing your tires and wheels. Some wheels just may not be up to the work you need them to do.

For example, if you mount large rims on your vehicle, then add low-profile tires to avoid major adjustments to other systems, they won't be able to handle off-roading as well as larger tires. There won't be enough sidewall on the tires to absorb the impact from off-roading. You could end up with dented or broken rims.

At the end of the day, Rockford drivers should always put safety ahead of appearance. That's why you shouldn't add custom wheels to your vehicle without consulting with your TJ's Auto Center Inc. tire and wheel professional. Cutting corners when installing custom wheels by not making necessary adjustments to all of the systems impacted by the change can result in dangerous operating conditions as well as repairs down the road.

The friendly and knowledgeable auto professionals at TJ's Auto Center Inc. want to remind Rockford drivers of the basics of vehicle safety: preventive maintenance, emergency preparedness and professional repairs. Stay safe, and stay on the road.
