DESCRIPTION
Each radiator fan is made of plastic. It is driven by an electric motor, which is retained on a shroud.
Scheme 8
The operation of the radiator fan is controlled by the ECM, depending on the signals from the engine coolant temperature sensor, vehicle speed sensor, A/C switch, and A/C mid pressure switch.
Note. Refer to the Service Manual for operation of each model.
