It’s a small part with a great importance. The thermostat manages the coolant flow through the radiator. When the engine is started and cold, the thermostat is fully closed. Engine coolant does not go through the radiator at all. Along with temperature rise of the engine, the thermostat starts to open. When the optimal temperature is reached, the thermostat is fully open. This results in a maximum radiator flow. When the system temperature drops again, the thermostat closes and so on.
