Radiator Cooling Fan Motor: Description and Operation
Fig. 38 Electric Cooling Fan
The electric cooling fan is controlled by a thermo sensor and a relay, the thermo sensor, is located in the radiator lower tank. When coolant temperature
reaches approximately 185°F, the thermo sensor contacts close, providing a ground circuit to the fan relay, which provides voltage to the fan motor.
When coolant temperature drops to approximately 178°F, the thermo sensor contacts open, opening the fan relay and shutting off the fan.
