I'm trying to do my fan swap right now and I can't get the freeking nut off the water pump. I know that it's a reverse thread. I've tried the propane wrench, the pipe wrench, and the air wrench (air chisel), and nothing. Got any ideas?

Looking at the engine, put the big crescent wrench and knock the hell out of it with a hammer toward the pass side of the truck....it will come loose.

You did the air chisel on the corner of the nut trick?? Time to go to Autozone and rent the fan clutch removal tool.

yeah just tried the hitting on the corner of the nut trick, and it was just digging a hole in the nut.

They really make a removal tool for this?

They make a pulley holder tool, but most of the time you can get it loose by a good sharp strike on the wrench with a hammer. If looking at the pulley from the front, it needs to turn counterclockwise.

I had the same issue last week, eveyone made it seem that it was a piece of cake to remove, but it was a lot harder to remove compared to an obs one. The tool that autozone rents is just a flat bar with a square cut out to go around the nut. But that is useless when you have an adjustable wrentch to go around the nut. I decided to make a tool for it out of some 1/2" flat bar and some random fastners laying around the garage. This is what teh tool looks like it just uses two screws to go into the pully holes and secures it while you turn the wrench.

You are turning the nut towards the passanger side right?

Finally got it with the air chisel!!!! Now... Do we need the nut on there to hold the pulley in place? What holds the pulley on?

the pulley is pressed on
