Hey guys thanks for the help,

So im changing my water pump and im having trouble getting the clutch fan off, there is a big nut attaching the clutch to the pulley and when i change turn that nut both the pully and clutch move, when i hold the clutch and turn that nut just the pully moves rotating the belt. Any help on where to go from here is greatly appreciated. Thanks

 

I use vice grips clamped on the water pump pulley, and a big adjustable wrench on the nut.

 

Air chisel did the trick for me.

 

got it thanks, the new water pump came with paper gaskets, do i have to use lube for it, if so can i use silicone?

 

I would probably put some rtv around the paper gaskets for insurance. I know all of the older 350s used paper gaskets for the water pump and they were fine but the newer trucks got the metal gaskets.

 

There's a special tool that uses steel dowels that slide into the pulley in 4 locations.

I used a pipe wrench on the pulley with a wooden shim to keep the wrench from biting into the pulley, my uncle had a wrench specifically for clutch fan nuts that you could attach a 1/2" drive ratchet to use as a break-over bar.

EDIT: Didn't read the whole thing and read that you already had it off.

 

Just wanna say thank you, this was my first major job and its a good little pick me up, only major bump i hit was that big nut and not having a big enough wrench. Water Pump Complete!!!
