UPDATE: I installed a new fan motor. I typically take pics of everything, but I was having memory card issues. Sorry, no pics. FYI, I never did find anything in the FSM about replacing the motor.
I picked up a fan motor from Autozone for about $100. The fan box said VDO on it (good company), but the Autozone folks said it was made by Siemens.
Tools Required:
Medium Flat Screwdriver
5/16th or 8mm socket & wrench (5/16 is correct)
Needle nose pliers
small torx wrench or socket
To remove the fan, unbolt the two bolts at the top of the fan shroud. The bolt appears to be 5/16 SAE, but an 8mm socket fits. Next remove the fan plug found near the radiator cap. Push the red pin out of the plug, then press down on the rear tab. These Jeep plugs are a PITA, be careful not to break the plug. There are no bolts on the bottom of the shroud. The bottom is held in place by clips. You may be able to simply tug hard on the shroud. I chose to use a long screwdriver to access one of the clips from the underside of the jeep. It's a tight fit if you are running a front skid.
Once the shroud is out of the vehicle, remove the fan blade. There is a small spring clip that you need to slide off the motor shaft using a screwdriver and/or needle nose pliers. Once you do this, there is another small steel plate that you must pop off the fan face. Once this is done, tug hard on the fan. I placed my feet on the edges of the shroud and bent down to remove the fan.
After the fan has been removed from the shroud, you may remove the old motor. Use the same socket to remove the three fan hex screws. You will find that the new motor doesn't fit quite the same, and will require spacers found with the installation hardware. I used the taller spacers. Since the old screws will be too short, use the torx screws that come with the new motor.
Route the new fan wires the same way as the old fan motor, and splice on the old plug. The new fan motor had the correct wire colors (blue and black) as the old motor, so no guess work was required.
Installation is the opposite of removal.
Thanks!
