Radiator Cooling Fan Motor: Description and Operation
This auxiliary cooling fan circuit consists of a coolant temperature sensor, a relay and the fan. When the coolant sensor reaches a predetermined
temperature, it closes the circuit to the relay coil, which energizes the relay, passing 12 volts to the fan. When the coolant temperature decreases below
the set point of the sensor, the circuit to the relay opens and 12 volt power to the fan stops. The fan only operates when the ignition is "ON" and the
coolant temperature sensor is above the set temperature.
