Fan clutch nut torque?
Does anyone remember what the torque value is for the fan nut clutch? Need to put a new one on. Old one is stuck soooo bad almost destroyed it in it's removal. Tried PB blaster and everything else under the sun (Yes, I know it is a left-handed thread) Might have to end up sawing or burning it off. Only reason I can think of that it is so bad, is with all the road salt and calcium chloride on the winter roads, some must have came thru the radiator and corroded it permanently on the pump. I think it's the original.
Have searched the forums, with no luck.
Thanks.

not sure what method your using to turn it but im guessing a wrench. I had to make a wrench out of 4"x1/4" flat stock. Make sure the pulley isnt spinning. I had one guy turning while one jammed a block of rubber cover wood in between the two pulleys so it wouldnt spining. Never done it but maybe try to heat it a bit with a torch

Let's put it this way...I measured across the flats of the nut, and bandsawed a piece of 3/8 steel to make a wrench before I started (48 mm) Left plenty of meat on both sides of the cutout to ensure strength. Bent the 3/8 steel. The shaft isn't turning, because I have a small ratchet-strap wrapped twice around the shaft, down to the crankshaft, and ratcheted tight. I can see it isn't turning. Soaked it in PB blaster two days. Moved up to using a cold-chisel on one of the edges of the nut trying to turn it. It just laughed at me.
It is probably gonna get slagged down (burned off) or if I can, sawn off. Either way, the fan clutch is probably gonna be ****canned when done. Already have a new water pump on the new engine, no core charge needed, so, all I really am gonna need is the fan and the front pulley.
So, just put Lok-Tite on it, and crank it down until I pop a hernia, and not worry about the torque?

I spoke to my friend, a diesel mechanic for over 20 years, and he said not to put any on. He said it would be hell for the next guy trying to get it off. So I tightened it up with a hammer gun, turned it on, revved it all the way up and shut it off.......fan stopped abruptly and remained on. If you don't have a hammer gun, you should probably use loctite.

i read from many experienced members here who over the years far exceed 20 yrs experience,that have reported on many occasions to have fans fly through their radiators.
but that's ok, when (not if) it happens.....................
you can't say we didn't warn ya lol.
ask tjc transport,why he fixed idi's statement above by adding in the loctite comment.chances are he has a story to share with ya.
