I need Help. I have a 96 Buick Riviera 3.8 Liter. I am trying to remove the power steering pump pulley. The pulley hub has a recessed socket cap screw which takes a 3/8" allen wrench.I'm not sure whether it is a right or left hand thread. The pulley turns clockwise, viewed from the front face. It is very tight,and I'm afraid I maybe tightening instead of loosening.
Thanks for any help. Rivet.
