A thermostat regulates the flow of coolant to maintain the engine's optimal operating temperature. When the engine reaches 190 degrees, it opens to prevent overheating, and it closes when the engine is cold to help it warm up faster. You typically replace this component if your engine is overheating, running too cold, or if coolant is leaking from the thermostat housing.
