Radiator Cooling Fan Motor: Description and Operation

DESCRIPTION
The A/C fan is 290 mm (11.6 inches) long with five unequally spaced blades to provide air flow through the radiator/condenser. The fan is driven by an electric motor which is attached to the radiator support.

OPERATION
The fan motor is activated by a coolant temperature switch. If the vehicle is equipped with A/C, a second switch can activate the circuit. The non-A/C vehicle uses a fan with five blades which are unevenly spaced and have curled tips to provide minimum noise. A/C equipped vehicles have a fan shroud to prevent recirculation of air around the fan.
