An Oil for All Seasons (Engine Oil Selection)

You swap your winter boots for flip-flops in the summer.  Why not change your winter engine oil for summer, hot-weather oil?  While it may seem like it makes sense, there's some good news.  Most drivers don't have to, and here's why. Engine oil can be made in different thicknesses.  That thickness is called viscosity, how easily it flows.  Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well.  So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather.  While there was a time when oils could be only made in one viscosity, times have changed.  Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls.  It self-adjusts to match the conditions.  Now that's what I call a great invention. In most temperate climates, you don't have to swap out the type of oil you use ... read more

Cool Breeze: Air Conditioning Service at Thom's Four Wheel Drive in CHICAGO

Most Illinois auto owners know that their vehicles need regular preventive maintenance like changing the oil and filters, rotating the tires and refilling the washer fluid. But did you know that your air conditioning system needs routine maintenance as well? Taking care of your air conditioning system can extend its life and prevent costly repair bills.Why is it important for CHICAGO area drivers to get routine maintenance on their air conditioning system? First, the refrigerant contains an added lubricant. As the refrigerant circulates through the air conditioning system, its parts are lubricated. This constant lubrication keeps the parts functioning well. But over time, this lubricant is used up, and without it, the parts will eventually seize up and fail.CHICAGO folks should understand, however, that the air conditioner will continue to pump out cool air even without the lubricant, so you won't know the sys ... read more

The Best Book that's Not a Best-Seller

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance. And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock.  Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it. Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what ... read more

Don't Neglect Your Spare (Spare Tire Care)

If you've ever had a flat tire, then you know welcome it is to have a spare tire that is properly inflated, in good shape and easy to get to.  Problem is many of us don't even give our spare tire (if we even have one) a second thought. If you have an SUV or truck with a spare, it may be mounted outside the vehicle, such as on the tailgate or underneath the vehicle.  All of them, especially those underneath, take the brunt of debris, moisture, salt and dirt from the road surface, a potpourri of corrosion potential.  The hardware that holds these on can rust into a solid mess, making it hard for you or even a roadside assistance service to get off.  If you have one of those, have it checked and maintained at your vehicle repair facility on a regular basis.  They should be lubricated and cleaned periodically, and some recommend doing this service every time you have your tires rotated.  If the spare is the same size as the tires on the vehicle, it may be a go ... read more

STRAIGHT TALK ABOUT STEERING (Loose Steering)

Perhaps you've heard someone use the term "loose steering." And it's pretty much what it sounds like.  You turn the steering wheel and the vehicle's wheels don't seem to go exactly where you thought you were pointing them.  You have to constantly make steering adjustments.  Loose steering is sloppy steering, and it can be a safety hazard.  You need to be able to control your vehicle with pretty much the same precision as the way it was when it came off the assembly line.   If the steering in your vehicle is starting to feel loose and sloppy, there may be some significant suspension issues that need examining by a trained technician. How do you know if your vehicle needs to be looked at? Try turning the steering wheel and see how much play is in it.  One rule of thumb: if you can turn it the distance of a quarter and a dime placed side by side without seeing the outside wheels move, it's time to have it inspected by one of our technicians. Our Thom's F ... read more

Don't Do It Yourself (Perils of DIY Vehicle Repair)

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies.  Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s. Today's most hig ... read more

Before You Buy that Used Vehicle (Having a Used Car Inspected Before Buying)

Let's face it.  New vehicles are expensive, so finding a good used one can save drivers a lot of money.  It's tempting to look through ads, find a private seller who has what you're looking for and pay a price you think is a great deal.  But when you go over to look at a used car, do you really know what to look for to uncover potential problems with it? The answer is probably no.  Used cars can look great on the outside, maybe even have lustrous paint and a super clean interior. But is it possible that vehicle's been in an accident? Does it have electrical problems you can't detect easily? Is any fluid leaking that you don't know about? Think about it.  You are about to spend thousands of dollars for a complex machine and you're considering judging its condition without much expertise.  That's why it makes sense to have a qualified technician inspect any used vehicle you're considering buying. Many vehicle repair facilities will do it for around ... read more

Timing Belt Replacement in CHICAGO

Today we want to talk to CHICAGO drivers about timing belts. They're something that many drivers don't know much about and yet your vehicle won't run if it's broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner's manual, it's not the kind of thing that most CHICAGO area auto owners remember because it's not well understood.Let's review what a timing belt does. As most know, the engine's power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel, pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at ... read more
