【Symptoms of a bad thermostat】: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause a lack of heat from the heating system.When the thermostat is stuck closed, the engine might overheat. The thermostat may also need to be replaced if the thermostat housing is leaking coolant.
【Function】:A thermostat is a temperature-sensing device that measures the temperature of engine coolant. The component is designed to know when to open and close so that internal combustion engines can work at an efficient temperature. Thermostats remain close if the coolant is not hot enough.
