heh I had a very intimate dealing with the power steering pump on my '93 ssei. The bolts are easy to get out really, just line the holes on the pulley up with the bolts, there only two of them so that is fairly straight forward. The difficult part for me was getting the damn thing out of there! Its kind of a pain to find the right combination of angles to get the thing out but trust me, it'll come out. It won't seem like it but just keep trying to rotate it and pull down until you find the right way, even push it back towards the rear of the engine as far as it'll go and rotate some more. I'm pathetic so it took me like 20-30min the first time, and that was after it was unbolted! The manual explains how to bleed the system but I let mine sit dry for like 6months and all I did was hook it up, start the engine, and kept feeding it fluid. Turn the wheel and feed it more. Wait like 5min and feed it more. It'll take more than you think but after all that it turned fine, no hard spots or sloppy steering. Anyway just be patient and it'll come out without too much trouble. Getting it IN is a whooollle 'nother story. But its possible so good luck!
Stuff got done.
