Twin Electric Fan Assembly (Freelander 2)

The dual electric fan assembly is mounted to the fan shroud and bolted to the rear of the radiator. The fans draw air through the radiator to regulate coolant temperature and supply cooling air to the engine compartment.

The fans are controlled by the fan control module, which receives a pulse-width modulated signal from the ECM with a pulse duty cycle of 0 - 100%. The ECM varies the PWM signal depending on the input data received from various sensors. The fan control module uses the PWM signal to determine the required output voltage supplied to the two cooling fan motors.

For more information, refer to the chapter: Electronic Engine Controls - 2.2L Diesel (303-14 Electronic Engine Controls - 2.2L Diesel, Description and Operation).

Under certain operating conditions and with the ignition off, the fans continue to operate under the control of the ECM to provide engine cooling.
