A thermostat regulates engine coolant temperature by controlling the flow of coolant between the engine and the radiator. When the engine is cold, the thermostat stays closed to allow the coolant to warm up quickly to the correct operating temperature. Once that threshold is reached — in this case 180 degrees Fahrenheit — it opens to route coolant through the radiator and dissipate heat. A thermostat that sticks open will cause the engine to run too cold, reducing efficiency and increasing wear; one that sticks closed will cause rapid overheating, risking serious engine damage and pump downtime.
