On chevy fans, they have four studs around the outside holding the fan onto the waterpump and pulley. On every gas engine fan I've ever seen, they have slots running from the holes to the outside of the fan mounting flange, I dont know why but they do. No, this diesel fan does not have the slots, it is just has holes. Also, chevy fans have a little nipple-stud thing in the middle of the pulley, and I'm guessing that is what the fan is stuck on, but I cant think of any way to get it off. I'm going to mess with it today and will get some pics and report back.

Oliver, if I ever get around to building a fresh engine for this thing, and decide to stick with a 6.2, I'll probably try to piece a turbo kit together, but we'll see. Do you know of any special method to get 6.2 fans off?
