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

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.

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
