Breathe Deep With Your Cabin Air Filter

Bad air quality while you're driving around CHICAGO is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they're fairly new on the scene, a lot of folks don't know about them yet.These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as three microns. By contrast, a grain of sand is about 200 microns.So your cabin air filter can clean out dust, pollution, pollen and spores to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner's manual or ask your service advisor at Thom's Four Wheel Drive, but they typically need to be replaced at around 12,000 to 15,000 miles (19,000-24,000 kilometers).The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, so ... read more

For 4x4s (Maintenance of 4x4 Vehicles)

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow. But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement.  Here are some of the key things to keep an eye on: Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisor will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfe ... read more

Recommended Service Intervals at Thom's Four Wheel Drive

Most people in the CHICAGO area are aware that automotive manufacturers have recommended service intervals. Following recommended service intervals is very important. The engineers that design our vehicles have tested the various systems and components to meet durability and safety standards. Some of these standards are self-imposed and others, like those for emissions components, are government mandated for areas in Illinois.The maintenance schedules are designed to achieve the standards. Think of the benefits of following recommended intervals as falling into three general categories: Protection, Efficiency and Safety.Protection. Let's start with motor oil. First of all, the engineers recommend a particular weight and type of motor oil for your vehicle. All of their oil change recommendations assume using the proper motor oil. Motor oil contains detergents and other additives that clean the engine and provide corrosion resistance. Ov ... read more

A Door No One Can Step Through (Fuel Door Repair and Maintenance)

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you. When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time. A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it.  You probably want to take care of ... read more
