Radiator Cooling Fan Motor: Description and Operation

Fig. 13:

DUAL FAN MODULE

All models use electric motor driven fans. The fan modules include a motor support and shroud. The module is fastened to the radiator by screws with U-nuts and retaining clips.

The dual fan module is a combination of 2 fans mounted in a one piece shroud which operate at two speeds and are simultaneously activated. The dual fan system improves engine cooling and air conditioning performance in hot weather and severe driving conditions, while reducing fan noise and power consumption. Attempts to reduce high temperature gauge reading by increasing engine speed, at the same vehicle speed, can increase high temperature.
