Warm weather or cold, CHICAGO drivers still need to think about their vehicle's air conditioning. Most CHICAGO people don't service their air conditioning until after it fails. At Thom's Four Wheel Drive, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on. Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at Thom's Four Wheel Drive in CHICAGO.The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all CHICAGO vehicle owners know that air conditioning repairs ... read more

Good vehicle care for us CHICAGO residents has always meant taking our vehicles in every spring and fall for a check-up. Vehicles needed routine maintenance to prepare them for the changes in weather. Today's vehicles aren't quite as sensitive to seasonal changes. Older vehicles required different weights of oil for summer and winter. But today's engines can run on the same oil all year. Both the engines and the oils have been improved.Antifreeze—or coolant as it's also called—protects the engine from both freezing and hot temperatures and thus is required by the engine year-round. Modern coolants don't have to be changed as often as they did in the past, but your owner's manual has a recommendation for when it should be replaced to extend cooling system life.Getting a spring and fall checkup at Thom's Four Wheel Drive in CHICAGO for your vehicle is still good auto advice.First of all, there is a lot of preventive auto maintenance involved in ... read more

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem. Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces. If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, even ... read more

Most CHICAGO drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine; a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.These hoses can develop leaks, so it is a good idea for CHICAGO drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why power steering fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owner's manual for the right type - or just ask your friendly and knowledgeable pros ... read more

Today's report from Thom's Four Wheel Drive is on vehicle batteries, why they die and what we can do to lengthen their life. Most of us have had a dead battery at one time or another. In fact, it would be very unusual if you hadn't. You may be surprised to learn that only 30 percent of CHICAGO vehicle batteries last for 48 months.Now that's an average. How long a battery lasts depends on many factors. You may not know that one of the biggest factors is the temperature where you live and drive around in Illinois. You might suppose that cold weather was harder on batteries because it takes more power to crank a cold engine, but the opposite is actually true. For more information on your battery, please visit us:Thom's Four Wheel Drive4118 N PULASKI RDCHICAGO, Illinois 606417735775701 Batteries in very cold climates have a life expectancy of 51 months as opposed to 30 months in very warm climates.

We usually take our vehicle's easy steering for granted until something goes wrong.  Power steering is what makes it almost effortless to turn the steering wheel, aiming your vehicle in the direction you want to go. Without the assistance of power from the engine, steering would be a laborious process, so you want to make sure the system is working well. Power steering systems are usually one of two types, hydraulic and electric.  The hydraulic type uses a pump that is driven by either a belt or an electric motor.  This system uses hydraulic fluid to create pressure that gives your steering the power assist.  Since that pump is always working, time and distance traveled eventually take their toll, and these systems need to be periodically inspected.  Also, while that hydraulic fluid can last for years, it should be replaced periodically as it degrades over time. Your vehicle's owner's manual contains the manufacturer's recommendations. A technician can check fo ... read more

The serpentine belt is aptly named since it snakes around under your hood. It may lack its namesake's fangs, but it sure packs a wallop when it breaks.The serpentine belt powers a lot of engine systems. It runs the alternator, which charges the battery; the water pump (on some vehicles), which cools the engine; the air conditioning, which cools the driver and passengers; and the power steering pump, which allows for easier steering. When the belt breaks, all of these systems shut down.Okay, so maybe you can live without air conditioning and power steering for a while, but your battery can't live very long without an alternator, and when the cooling system goes down, your vehicle engine will overheat. That's why CHICAGO drivers should never wait to get a serpentine belt replaced.Serpentine belts are fairly inexpensive at Thom's Four Wheel Drive in CHICAGO. And they look downright cheap when you compare them to the cost of an overheated vehicle engine, a tow truck, time lost on the road ... read more

Let's talk about something critical for all CHICAGO drivers: your brakes. Your vehicle is heavy, and it takes a lot of muscle to bring it and your passengers to a safe stop – so everything needs to be in good working order. Here's an explanation on how your disc brakes work: The wheel hub keeps your wheel attached to your vehicle. The brake disc – or rotor – is attached to the hub and rotates with the wheel as you drive around CHICAGO. Your brake pads clamp onto the rotor to slow the wheel.The brake caliper straddles the rotor and squeezes the rotor to slow it down. The calipers contain brake pads which press on the rotor when you put your foot on the brake. The brake piston causes the calipers to squeeze and release as you use your vehicle brakes.Your brake pads start to wear the first time you step on the brakes. Eventually the ... read more
