We tried and tried and infact used 2 diffent removers. One was specificly for removing the power streering pully / something else. The other we used was a 3 claw pully. Neither worked? Cant get that damn thing off the head? How do we do it, i mean we had the 3 claw chip the back side of the pully we had it so tight, the other that was just a screw with a nut setup that would just make poping sounds when it would get tight. We sprayed it down overnight with wd40 no luck. I think this is some BS engineering by gm, some of the stuff i see anymore is obvouisly intentional in the way that they dont want the common person to work on their cars anymore. I mean on lt1/4's weve got the pully with the 3 holes in it where you just rotate to get to the bolts, why the change? Thanks for the help.

 

Don't need to take the pulley off. Work the mounting bolts out a little at a time evenly with an open ended wrench. Takes a little time and patience but it's not hard.
