Me and my friend have been tryin to get the fan clutch removed from the water pump and it aint coming off. We have tried it with the belt on and it slips. We have tried a strap wrench and wrap a belt around it and it still hasn't worked. Does anyone know how to do or has anyone done it before that could tell me how they got it off.

 

It has a reverse thread: Righty-loosey.

Search in this forum (3.0) using "fan clutch" or "under-drive pulley"; should get you many hits. Pretty sure Underdog had a good write-up (edit: Yep http://stuffforyourranger.com/How_To...nderdrive.html). Might also search on "electric fan".
