Function: Drives the radiator fan to move additional air through the radiator.
Signs of Wear: Engine overheating, fan doesn't turn, squealing noise.
The cooling fan is set to run when the engine reaches a specific temperature, usually around 203°F.
The cooling system is operated by a thermostatic switch so that the fan operates when the engine reaches a specific temperature. As the engine temperatures reach close to 203°F, the engine computer operates a relay to allow power to flow from the battery to the cooling fan. The fan forces air across the radiator in order to remove excessive heat from the cooling system. As the temperature of the coolant drops, the engine computer turns off the cooling fan relay until coolant temperature rises again.
