Fan clutch nut removal
I have a 1997 Ford f-150 with a v-6 - 4.2L engine. I am having difficulty removing the nut. Any suggestions? Also what way do i turn the nut to loosen. I have a chilton manual that says i need to turn clockwise to loosen. I have seen a thread that states the opposite. Does anyone know the correct answer? Any and all help would be greatly appreciated. Thanks in advance.

I had to change out timing chains on my 4.6l V8 two years ago, we went by the book, figured out the book was wrong, got the fan off, did the job, put it back together, ran it down the road and BLAM!!!! the fan flew off and went through my radiator. As it turns out we over torqued the threads on the water pump that hold on the clutch fan and must have produced a hairline crack, and caused the cheap pot metal to break. Ended up buying a new radiator and an Electric fan. Be careful...and good luck.

From the Ford service manual:
NOTE: The fan clutch has RH threads.

I'll try to find the pictures of it, but a member here made a pulley holder by hammering some 3/4" EMT ( thin wall electrical pipe ) flat, and drilling holes at the spacing of 2 of the bolts, and then got longer bolts and bolted this handle to the pulley.
I bought a pulley holder for when I did my E-Fans, others have just wedged a large screw driver, or pry bar in there between the bolts as well.
Here is a picture of them, and the part numbers :

I might add that I had problem removing my OEM fan for Mike T's Electric Fan and Underdrive Pulley upgrade. Couldn't seem to get the OEM pulley off after removing the nut.
Eventually figured out from an old, old post that behind the nut was a large washer. Well, the washer did not fall out when I removed the nut, so I was constantly applying pressure against it with the Pulley remover. Broke one remover, went and got another and decided I had better do a search to find our what was happening.
The heat resistant sealant applied at the factory had oozed out enough to contact the back of the washer preventing it from falling out. A small mirror and light finally revealed it still there and I ended up prying it out with a small screwdriver. Pulley fell right off once I took the washer out.
