The main functions of the Engine Cooling System are to carry heat away from the
engine and maintain the correct operating tempurature. The system accomplishes this
by circulating antifreeze/coolant around the components where heat is generated
and carrying it to the radiator to be cooled.
In the engine cooling system, an appropriate amount of an antifreeze/coolant and
water mixture is necessary to help reduce the risk of the engine overheating and
freezing. Another important feature of antifreeze/coolant is that it inhibits rust
and corrosion in the cooling system.
