remove flex fan

I'm trying to remove my flex fan for an electric fan install. Problem is I cant get the *&% thing off. So far I've removed the radiator (and a whole bunch of other stuff to get to it) to get better access. I've busted the fanbelt in trying to use that to hold the pulley as I try to undo the nut. I need a method of holding the pulley/waterpump while I loosen the nut (reverse thread, I think I have that right). I dont have a whole lot in the way of tools though. Once done with this, I'll be able to get going again.
Right now I'm at a loss as to how to proceed to get it off. Any ideas?

I use a bike wrench 32 mm as it is thin & give it a sharp rap with a dead blow hammer.

You know, I can't remember if it's the V-belts or the serpentines..... (funny, since I did the same thing myself) but one of them is reversed threads. I know I was bashing mine all afternoon before I realized that.

94 should be a reverse threaded V-belt from what I remember.

Yah, I think I'm ready.

Its a '94 - v-belt. The 4.0 in the '97s introduced the serpentine belts.

Scott,

I don't know if you want to take your tool kit this far, but this is what we use at the shop:


http://www.lislecorp.com/tool_detail.cfm?detail=751


You attach the appropriate sized wrench to your fan clutch, then attach the rod to the wrench, and then attach the rod your pneumatic hammer. The smallest burst will shock loose the nut and your fan clutch will come off very easily. This arrangement is expensive and complicated, but it works beautifully as the impacts from the pneumatic hammer will easily shock loose the fan clutch nut without having to hold the fan clutch stationary.

Another method is to use the appropriate sized wrench and then hit it with a hammer to try to shock loose the fan clutch nut.

My 97 has a 36mm nut. I'm not sure if the 94's and 95's are different. I don't think they are though.

Thanks for the above sets of suggestions. I got some help with some better tools and we managed to shock it enough to come off. And for the record - yes - its reverse thread.
