OEM Automotive Thermostats

The thermostat is typically located where the coolant leaves the top of the engine, just below the upper radiator hose. When your engine is cold, the thermostat remains closed trapping the coolant in the engine. The coolant is circulated in the engine by the water pump until it warms up to a predetermined point and the thermostat opens. Hot coolant can then circulate to the radiator where it is cooled and returned to the engine. A stuck thermostat will cause the engine to overheat or not heat enough.
