Then, I took a 15/16" 6-point socket (24mm is the correct size, but fits slightly looser) and welded a 3/4" wrench (out of my box of Taiwanese tools destined for customization that I keep around) to the socket.

it took between 70 and 100 foot pounds to break the nut free on the first 4 or 5 alts (holding the T50 with a torque wrench helped me quantify this) .... THEN I was changing the pulleys on god-likes-tebow's SRT6 and the T50 snapped off (at about 120 foot pounds IIRC) ....

So I bit the bullet and slipped the 2 clips that hold the fan shroud off, unplugged the fan and pulled out the shroud. I have 5 or more 1/2" impact guns, so I picked one of the shorter ones and had the pulley off in a jiff .... the impact method is 5 minutes faster as it turns out.

worth mentioning, I like to slip a piece of sheet metal (8" x 8" or larger alum or steel) up against the fins of the radiator when working near it (particularly with an impact) so i don't lay (bend) any fins over accidentally.

here are a couple of pics of the tools I made for this .... but impact is really the quickest way.
