I have done 3 of these this year, I have pretty much got it down. First thing you need to do is understand it sucks and will take a while, make sure youve got your patience with you.
The best place to start is by taking the upper ic tube off, everyone says you need a spanner wrench, I just use a craftsman strap wrench, always works. Then take it off of the ic, take the bottom tube loose from both ends also. remove your ic. take off our dis, alternator, (belt before all of this). Rent a pulley from autozone for $70 (you get the money back when you take it back and if you break it its their fault for using crappy tools) take your pulley off. This sucks by hand an impact with a wiggle socket is a big help. when you get the pulley off you will be able to access all of the bolts that bolt down your power steering bracket. Remove the bracket, p/s pump and lower ic tube. I know this sounds un necessary but it is a useful trick and actually takes less time. While you have this off be sure to inspect the ps hoses, a broken hose would really really suck, Ive been there. The stock p/s return line clamp is a piece of crap, replace it with a screw type clamp or risk redoing everything. With everything out attach the pressure line to your new pump and put some atf or ps fluid in the pump and turn the pump by hand until fluid comes out the return line. This will help prevent air bubbles, then attach the return line WITH THE NEW CLAMP remember this is experience talking. When you are sure everthing is tight and not going to leak slide your bracket back in and put a couple bolts in it to hold it in place loosely. Place your lower ic tube in and get it situated. Bolt on the bracket, tighten the lower ic tube to the bracket bolt your new pump in place (make sure you put the steel support back on) and then put on your pulley. Replace all the other stuff in reverse order. Be sure to put the alt hinge bolt in BEFORE the ic or you will be shortening the bolt. If you try to do this by just taking out the pump it will take forever and the lines arent long enough to really get them on good, and its all wreching. If you do it my way, air tools and ratchets all the way, everything is smooth and you know how well the hoses are on, plus a free pressure hose inspection.
