This vehicle is equipped with counter-rotating engine cooling fans. The right hand fan will require the use of GE-47827 or equivalent for fan blade removal. The left hand fan blade can be removed using a normal six point socket.

Removal Procedure

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: To help avoid personal injury or damage to the vehicle, a bent, cracked, or damaged fan blade or housing should always be replaced.

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. Remove the fan shroud assembly from the vehicle. Refer to Cooling Fan and Shroud Replacement .
