What causes a thermostat to go out?
Once the coolant engine reaches proper operating temperature, typically 180 to 200 degrees, the thermostat opens up and allows the coolant to flow through the engine. Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.
What happens if a car thermostat is stuck closed?
