    The hardest part is keeping all of the vacuum lines and emissions crap sorted out. You do have to remove the PS pump. Use masking tape and put a piece on both ends of a connection with a 1,2,3...etc it makes putting everything back together easier.

    When I did mine, I had to remove/pivot/loosen every accessory bracket off the front of the motor, because for some stupid reason GM has them all threaded into various locations on the water pump /forums/images/graemlins/angryfire.gif. If I remember correctly, the PS pump was the hardest. I believe there's a hidden bolt on the PS pump bracket.....

    I have no emmisions stuff in the way, BTW. Just take your time and step-by-step. You should also consider replacing all your belts while everything is apart.
