Learn More About Radiator fan switch
The radiator fan switch, or thermoswitch, is a temperature-sensitive electrical switch typically mounted on the radiator or coolant housing. It constantly monitors coolant temperature and completes the electrical circuit to turn on the radiator fan when the engine gets too hot. A failing switch can cause the fan to run continuously and drain your battery, or fail to engage entirely, leading to severe engine overheating. This category provides exact-fit OE-specification replacement switches featuring highly responsive bimetallic elements and durable brass housings. Select your vehicle to find the precise thermoswitch required to keep your automated cooling system functioning flawlessly.
