When an engine coolant thermostat sticks open or closed, the engine can run hot, warm up slowly or show a wandering temperature gauge. Low coolant, a failing water pump, a weak radiator fan or a leaking hose can be behind the same signs, so find the cause before buying. If a stuck thermostat is the cause, this Beck/Arnley thermostat replaces it.
