Thermostat

Any liquid-cooled car engine has a device called the thermostat that rests in between the engine and the radiator. The function of the thermostat is to block the flow of coolant to the radiator until the engine has warmed up to the optimal temperature. No coolant flows through the engine when the engine is cold. Once the engine has warmed up to generally about 200 degrees F or 95 degrees C, the thermostat opens. By allowing the engine to warm up as swiftly as possible, the thermostat reduces engine wear and tear, deposits and emissions.
