Radiator Cooling Fan Motor: Description and Operation

RADIATOR FAN

- The radiator fan is made of plastic. That is installed to the electric motor, and is located onto radiator straight by shroud.
- The vehicle without air conditioning has the radiator main fan only. Thus, the vehicle with air conditioning has the radiator sub fan, too.

RADIATOR FAN CONTROL





A: WITHOUT A/C MODELS
The ON-OFF control of the radiator fan is governed by the ECM which receives signals sent from the engine coolant temperature sensor.





B: WITH A/C MODELS
On models which are equipped with an air conditioning system, the ECM receives signals sent from the engine coolant temperature sensor, vehicle speed sensor 2 and A/C switch. These signals simultaneously turn ON or OFF the radiator main fan and radiator sub fan as well as setting them at "HI" or "LO" speed.
