Caution: An electric fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the battery negative cable.
2. Remove the secondary air cut-off bracket:

•	Remove the bracket bolts.

•	Disconnect the bracket from the fan housing.

•	The primary fan motor

•	The primary fan cooling switch (at the upper LH of the radiator)




6. Remove the auxiliary water pump from the primary fan housing by removing the two clips.
7. Place a catch basin under the fittings and remove the upper transmission oil cooler fitting and loosen the lower transmission oil cooler pipe fittings.



8. Remove the fan housing bolts and remove the fan housing from the vehicle.
9. Snug the lower fitting in order to minimize fluid loss while the fan housing is removed from the vehicle.



10. Remove the fan motor nuts (1).
11. Remove the fan motor from the fan shroud.



12. Remove the fan blade retainer clip (1).
13. Remove the fan blade from the fan motor.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
