hehe on mym sisters 4.3 v6 vortec powered s10 it has that huge nut/bolt type deal on the fan/clutch-pully connection. My brother in law finally found the worlds largest crescent wrench to go around the thing and we still couldn't get it off. It turned all the pullys with it! so... finally remember I had a rubber mallet in the truck. a couple real hard hits finally got it to crack free enough that we could turn it without everything else turning with it.
