Your cars cooling system is vulnerable to the cold temperatures in the winter months. Proper maintenance of your cars cooling system can prevent freeze-ups and corrosion problems.
The coolant in your car's engine is a mixture of water and anti-freeze, a chemical to prevent freezing. Straight water is the best liquid to remove heat from your engine, but will freeze below 32 degrees F, so antifreeze is necessary. Before each winter season you should have your coolant checked by a mechanic for PH and freezing point. It's a simple test which can be done in a few minutes and can save you repair bills and hassles down the road. You can buy a tester at your local parts store and test the coolant yourself, but you will need to be careful to check the levels when the engine is cold. If the PH or freezing point is off, it's time to change coolant. A certified mechanic will have the proper equipment to flush and refill your coolant system and properly dispose of the old coolant.
