FAN BLADE
There are no repairs to be made to the fan. If the fan is warped, cracked, or otherwise damaged, it must be replaced with only the recommended part for adequate strength, performance and safety.

Figure 29:

1. To remove fan from motor shaft, bench support the motor and motor shaft, while removing the fan retaining clip, so that the shaft and motor will not be damaged by excessive force. Surface burr removal may be required to remove fan from motor shaft. Do not permit the fan blades to touch the bench.
2. To install fan motor shaft, slide the fan over shaft. Support motor and shaft as above while installing fan retaining clip.

FAN MOTOR

WARNING: Do not disassemble the fan motor from the support bracket.

The electric fan motor is serviced as an assembly with the fan module.

FAN SHROUD
Some fan shrouds are equipped with flapped doors to prevent the shroud from restricting air flow at high speeds.
All vehicles have fan shrouds to improve fan air flow efficiency.

1. Install the fan module into the clips on the lower radiator attachment clips.

NOTE: For dual fan module applications, install the right fan module first and then the left fan module.

2. Install the fan module retaining screws and tighten to 7.5 Nm (65 inch lbs.).
3. Connect fan module electrical connector(s).
4. For vehicles equipped with dual fan modules, install the battery tray and battery.
