Thom's Four Wheel Drive

Sometimes busy CHICAGO residents dream about going back to the “simpler” days of our grandparents. But if you could travel back in time and take a road trip around Illinois in a Model T, you might change your mind. The improved designs and quality of today's automobiles have significantly reduced the amount of time CHICAGO residents spend at the side of the road during breakdowns. With proper maintenance, today's vehicles can stay on the road longer than ever before.Some of those improvements, however, have led to higher repair costs. For example, older cars often broke down from vapor lock. Gas vaporized while traveling from the gas tank to the fuel pump. No gas, no power. The car quits going. The solution was simple — you just sat by the road until the car would start up again. Today's CHICAGO drivers would hardly tolerate that kind of inconvenience, and it's likely that yesterday's CHICAGO drivers didn't care much for it, either. So on today's vehicles, the fu ... read more

We live such busy lives nowadays: work, social events, running the kids all over CHICAGO. Some days it's all we can do to keep track of everywhere we need to be. That's why you've gotta be organized. Smartphones, calendar apps - we have to keep track of it all.So let's talk about schedules. Specifically, automotive service schedules. And particularly, the scheduled services that are sometimes forgotten.Here is a list of 10 service items that are often overlooked by CHICAGO residents. They're all very important and need appropriate attention. So here we go, in no particular order.1. Power Steering ServiceBe honest; have you ever thought of this on your own? Your power steering fluid gets dirty and builds-up moisture over time. Cleaning out your power steering system means that dirt and gum are removed and your power steering parts are protected from corrosion. Next time you're in for an oil change, ask your Thom's Four Wheel Drive service advisor if it's time ... read more

If someone told you that your vehicle could have the same power but with a smaller engine, wouldn't that sound like great idea? Just think, a smaller engine would save you money at the gas station and you'd still get the same horsepower. The technology to do just that has been around for a long time. It's called a turbocharger. Race cars and other performance vehicles have been using turbochargers for years. It gives them a power boost without the need of a bigger engine, saving them fuel and pit stops. Automakers have offered turbo gasoline and diesel engines for years, but there were problems with durability. Plus drivers had to make some driving adjustments with the way turbos delivered power. Newer turbos, though, have been vastly improved, and manufacturers are including them in more models. For example, Jeep offers its 2019 Cherokee with a choice of two engines that each make about 270 horsepower. One is a 4-cylinder turbocharged engine and the other is a 6-cylinder conventional ... read more

Because 90% of our driving decisions are based on visual information, unobscured vision is paramount. Which brings us to the topic of today's Thom's Four Wheel Drive article: wiper blades. While this isn't the most exciting automotive subject, it's important. You wouldn't drive at night in CHICAGO with your headlights off, but a dirty or streaked vehicle windshield can catch the glare of the sun or on-coming headlights and make it just as difficult to see.Most of us in CHICAGO replace our wiper blades when they no longer do the job. They are so worn, hard or brittle that they can't clean the windshield. They may even be falling apart. In other words, we deal with our wiper blades from a failure perspective. We address them when they no longer function. The theory, "If it ain't broke, don't fix it," doesn't apply here. Instead, we should think about wipers blades as an important safety system that we should maintain rather than re ... read more

Just as our bodies need clean air to function properly, your vehicle engine needs clean air to operate efficiently. Let's go egghead for a minute. For every gallon of gas we burn driving on CHICAGO streets, 20 pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce 20 pounds of carbon dioxide?The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about 12,000 gallons of air to burn a gallon of gas in your engine. Clearly, your vehicle needs a lot of air to keep going in CHICAGO. A lot of clean air is best. You've seen the pictures of people in Japan wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your vehicle also works better when its internals are clean. When your vehicle air filter is dirt ... read more

Every CHICAGO car owner who has taken their car in for an oil change has been told that their engine air filter's dirty. Here's what goes into the determination of when to change the filter: First, your vehicle owner's manual will have a recommendation of when the filter should be replaced. Now, most air filters purchased in CHICAGO don't cost a lot to replace. It's just that Illinois people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at Thom's Four Wheel Drive can often save enough on gas to pay for itself before your next oil change in CHICAGO. Think about a dirty furnace filter in your CHICAGO home. When it's all clogged up, enough clean air can't get through. In your vehicle, that means that your engine can't get as much air as it needs to burn the fuel efficiently. So it makes do with less air and has to use more gas to move your vehicle around CHICAGO roads. Your vehicle actually needs about 12,000 times ... read more

These days many people in the CHICAGO area are really committed to making their cars last a long time. First thing: you've got to start with what you've got. It'd be ideal if people started with a brand new car, never missed a scheduled service item, paid attention to the severe service maintenance schedule and had regular inspections. But if you've had the vehicle for a while or bought it used, its maintenance history is what it is; and that's where you start.Go through the maintenance schedule for your vehicle and see what's been done and when. Have your CHICAGO service advisor at Thom's Four Wheel Drive do an inspection and come up with a list of stuff that needs to be done. Review the list and prioritize the work, talk about budget and make a plan to get caught up.Making a plan is so important. Suppose you go in for an oil change and learn you need your cooling system serviced, a transmission service and are coming up on a timing belt replacement in the next ... read more

Hey CHICAGO - this is something really amazing: Your vehicle uses 12,000 times as much air as fuel when you drive it. All of that air has to be filtered to keep your engine clean.That's like 100 gallons (380 liters) of air every block! The engine air filter is just another example of a very important but inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn't, well, it can lead to problems. Of course, your vehicle manufacturer recommends how often to change your air filter. But like most service intervals, where and how you drive your vehicle in Illinois affects when your filter needs to be changed.Dusty conditions around CHICAGO or polluted city driving means you'll need to change your filter more often. Our trained professionals at Thom's Four Wheel Drive can check your filter for you. In fact, it's often a routine part of an oil change.When you think about it, a clogged air ... read more

We live in a disposable society. Everything from elaborate packaging to our clothing. Even cell phones are disposable. When replacement is cheaper than repair, the term "built to last" goes by the wayside. An exception is our vehicles. They're still a very big investment and CHICAGO drivers want to make them last as long as possible.  We also want to make keeping them running as cheap as possible. When talking vehicles, it's all about preventive maintenance. There is an old saying that says, "A stitch in time saves nine," and that is really true when it comes to taking care of your vehicle. A great example is coolant service in CHICAGO.Your coolant not only protects your engine from overheating and freezing, it must also protect cooling system components from corrosion. Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That's why you need to have your cooling system serviced on a regular schedule.The same is true for your power ... read more

If you've ever been driving around CHICAGO and had a headlamp go out, you've probably just wanted to replace the bad bulb. If your car uses halogen headlamps, they dim over time.

We're at 4118 N PULASKI RD in CHICAGO, Illinois 60641. Or give us a call at 7735775701.Experts at Thom's Four Wheel Drive recommend replacing your halogen headlamps every year.

That way you'll have bright headlamps for those long Illinois winter nights.There are other types of headlamps in addition to halogen. There are the old standard bulbs that have been around for decades. These are OK, but you can usually upgrade to halogen. They cost a little more but you can't believe the difference. If you do a ... read more
