1. Do Not attempt to remove the fan/viscous fan drive assembly (2) from the vehicle at this time.

CAUTION: If the viscous fan drive is replaced because of mechanical damage, the cooling fan blades should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan blade assembly if any of these conditions are found. Also inspect water pump bearing and shaft assembly for any related damage due to a viscous fan drive malfunction.


2. Disconnect negative battery cable from battery.
3. The thermal viscous fan drive/fan blade assembly (2) is attached (threaded) to the water pump hub shaft. Remove the fan blade/viscous fan drive assembly from the water pump by turning the mounting nut clockwise as viewed from the front. Threads on the viscous fan drive are LEFT-HAND. A 36 MM Fan Wrench (1) should be used to prevent pulley from rotating.
4. Do Not unbolt the fan blade assembly from viscous fan drive at this time.
5. Remove the fan shroud-to-radiator mounting bolts.
6. Pull the lower shroud mounts out of the radiator tank clips.
7. Remove the fan shroud, electric cooling fan, and fan blade/viscous fan drive assembly (2) as a complete unit from vehicle. (Refer to 07 - Cooling/Engine/FAN, Cooling - Removal)
8. After removing the fan blade/viscous fan drive assembly (2), do not place the viscous fan drive in a horizontal position. If stored horizontally, silicone fluid in the viscous fan drive could drain into its bearing assembly and contaminate lubricant.

CAUTION: Do not remove water pump pulley-to-water pump bolts. This pulley is under spring tension.


9. Remove four bolts securing fan blade assembly to viscous fan drive.

CAUTION: Some engines equipped with serpentine drive belts have reverse rotating fans and viscous fan drives. They are marked with the word REVERSE to designate their usage. Installation of the wrong fan or viscous fan drive can result in engine overheating.
