Function of the Thermostat
In this closed cooling system is a device called a Thermostat. The Thermostat is very important and a very unique device. It is a valve that opens and closes depending on the temperature of the coolant water. It helps regulate the amount of water that flows thru the radiator to maintain the proper engine temperature. If the coolant is too cold, the engine does not operate economically and wastes fuel. If the coolant is too hot, the engine can overheat and not operate at all and damage other parts of the engine. Some newer vehicles have more than one thermostat in the cooling system. Generally this is for the different temperatures inside the passenger areas of the vehicle.
