F250 fan clutch nut removal

[_87TA_]

Ok so I'm changing a water pump on a 2001 diesel F250 and only thing I'm having trouble with is getting the damn fan off the pulley. I've tried a hammer to break the initial torque = pipe wrench slips off/ not enough force. Renting the proper tools from autozone = 1 doesn't fit/ still won't budge. Liquid wrenched the **** out of it = got everything wet. Took it off the eng = kept moving when trying to loosen. Temp installed it back on eng to keep it still with proper tool, pipe wrench, liquid wrench and hammer = nothing....
What... the... ****....
Anyone have any advice? Because I'm about to throw it through the windshield and order a whole new fan/pulley assy... and apparently a windshield....
Please and thank you.

What he said, along with the proper wrench is about a foot and a half long with a square cut out to put a breaker bar in it.
