How do you remove the fan and clutch from 5.2 Jeep engine?

Answer 1

According to the manual removal of the fan/clutch on the 5.2 can be accomplished by "grasping the belt or pulley with one hand and rotating the fan blade in the opposite direction"

In reality you'll need an item called a spanner wrench which will be nearly impossible to find from a local parts store. You can special order an adjustable spanner wrench or I could probably sell you the one I built when I removed my own fan. It's not a difficult item to build, essentially you'll need two lengths of flat stock, about an inch wide will do. Basically you need a longer section and a shorter section that can be bolted together to form a "y" and the ends if the "y" you'll need to drill a hole and insert a bolt, you may be able to put a nut on the bolt to keep it in place, I welded the bolts in the ends of the one I built. These bolts should be of a size that will fit in the holes on the face of the pulley. Once you've constructed a "y" bolted together so that the ends can be opened or closed, and installed a bolt at the ends of the "y" you can simply put a bolt in two of the four holes on the face of the pulley, now you can firmly hold the pulley with one hand and use a large adjustable wrench on the nut located at the rear of the fan/clutch.

At that point you should be able to turn the wrench and unscrew the fan/clutch from the pulley.

Note, the pulley is pressed to the water pump shaft so it is not essential for the fan/clutch to be in place for the engine to be run (on my Jeep I removed the fan/clutch and installed an electric fan instead)

I can provide pictures of both my jeep and the tool I built upon request and if you're not someone who can fabricate I would sell the tool I constructed for a nominal fee.
