When the engine is cold, the thermostat stays closed to block coolant flow to the radiator, letting the engine warm up faster. Once the engine hits a certain temperature, the thermostat opens up, allowing coolant into the radiator, where it can cooloff and keep the car from overheating. Thermostats can become stuck in the closed position and cause an engine to overheat. In this event, the coolant temperature will likely rise quickly to the boiling point determined by the system pressure capand exhaust to the ground. This condition is very rare; in most cases, the thermostat is not the cause of an overheating engine. Conversely, it can also become stuck in the open position causing the engine to run cold,making the check engine light come on, and the heater blows cold air.
