Tip #2: Cooling Systems

When your engine is dead cold, the morning before you start the engine is the best time for this, remove your radiator cap and look at the color of the fluid.  Most cars I look at it is green with a little bit of brownish deposits.  If you swirl around your finger in the fluid those deposits will make the green fluid turn brown until they settle down.  Well guess what, your cooling system is already in a state of degradation but don't get worried because you can do something about it.  You need to get your cooling system flushed or at least drain and refill it yourself.  The recommended service interval for your cooling is once a year.  It is cheap preventative maintenance.

Again thanks for your time,
Jon Grenon
