A thermostat is a temperature-controlled valve that regulates coolant flow to keep the engine at its working temperature.
It stays closed when the engine is cold so it warms up quickly, then opens to let coolant reach the radiator as the engine heats up.
The thermostat sits in the engine's coolant circuit. The correct thermostat matches the engine and its opening temperature.
