Cooling System

The Cooling System carries heat away from the engine and maintains the operating temperature by circulating anti-freeze/coolant through the engine, and carrying it to the radiator for cooling.

Modern automobiles operate in a wide temperature range, from well below freezing to over 100 F. The fluid used to cool the engine must have a low freezing point, high boiling point, and the ability to transfer heat. An adequate amount of antifreeze/coolant and water reduces the possibility of engine over-heating and freezing, as well as contains additives to prevent rust and corrosion in the cooling system.

Water holds heat well; however, water alone freezes at a temperature too high to be used in engines. The fluid in most vehicles mixes water and antifreeze or coolant. With this mixture, the boiling and freezing points improve significantly.

Coolant temperatures sometimes reach 120 to 135 degrees Celsius. Even with antifreeze added, these temperatures boil the coolant. To prevent boiling, the cooling system raises the coolant boiling point by pressurizing it. Most systems pressurize coolant at 14 to 15 pounds per square inch (psi) which raises the boiling point approximately 10 degrees Celsius.
