Fan nut...to remove mine, I used the end of a pickle fork to catch the nut on the right side. A quick blow with a hammer did the trick.
Simply spin the fan to the RIGHT and see if the nut is backing off the shaft.
If not, strike the nut again on the right hand side...spin the fan again to see if that did the trick.
Mine came right off.

When reinstalling...just catch the nut on the shaft and spin the fan to the LEFT.
It's much easier than you guys are making it out to be.

TwinTurbo,

Yeah, the pics are redundant for sure and like you said there's an over use of the arrows.
All in all, the pics did help to identify which parts needed to be removed.

In your write-up...I hope you'll address the torque specs for the alternator and even the "gotcha's" with regards to old hoses and such. I attempted to give a bit more detail but would be nice if there was a fresh thread.

Have fun!
