Radiator Cooling Fan: Description and Operation
Radiator FanDESCRIPTION
Each radiator fan is made of plastic. It is driven by an electric motor which is retained on a shroud.
FUNCTION
The operation of the radiator fan is controlled by the ECM. In a model equipped with an air conditioning system (A/C), the ECM uses for the control the signals from the engine coolant temperature sensor, vehicle speed sensor and A/C switch. The ECM on a model without an A/C performs the control based on the signal from the engine coolant temperature and vehicle speed sensors.
