Radiator Cooling Fan Motor: Description and Operation
Electric Cooling Fan
The electric cooling fan is mounted behind the radiator assembly and is thermostatically controlled. Vehicles with manual transmissions have a one
speed cooling fan. When engine coolant temperature has reached about 90°C (194°F), the temperature switch will close its contacts, allowing the electric
cooling fan to operate. Vehicles with automatic transmissions are equipped with a two-speed cooling fan for more efficient cooling. The temperature fan
switch has two pair of contacts, one of which closes at 90°C (194°F) and the other when it reaches 110°C (230°F). Models with A/C, are equipped with
an auxiliary cooling fan. This fan is controlled by a time-delay relay that also turns on the compressor.
These vehicles are also equipped with a time-delay relay, which limits cooling fan running time after engine has been shutoff. The relay that controls
this function is always energized when the engine is running. When the engine is switched off, the supply to the relay coil will be interrupted. After about
10 minutes, the relay will trip the supply to the fan motor, even if temperature switch is still closed.
