I was able to loosen those 2 studs from below using a really long wrench and a short socket without pulling the wheel. It'* a PITA, but it can be done.

Done! Details later....

Thanks for your help.

So we got the water pump replaced on Saturday. Took us about 7 hours total. It is not a hard job, but be prepared to remove a lot of stuff. For the motor mounts, it is easiest to remove both, and the bottom horizontal bolts on the body mount can be removed with a 3/8" flexible ratchet from the top.

Remove the alternator on the other side and the take off the PS Pump by removing 2 bolts lined up through the PS pulley. Remove the 3 idler pulleys. The bracket does not have to be completely removed (we removed 3 or 5 bolts, can't remember) and then when the bracket was loose, we pryed it away slightly to remove the last WP bolt. We used the paper gasket that came with the WP, and supplemented it with a very light coating of WP/Thermostat gasket maker. The small bolts called for 97 in-lbs, but I didn't have the low torque wrench, so we tightened it to 10 ft lbs (about 2 ft lbs more). It seems to be holding well, no noise.

Thanks for all the help. I join the cursing of the GM engineers on this one.

I'm doing the same thing right now, and i'm stuck on the motor mount.
I removed all the bolts but the mount barely moves and doesn't want to come out.
How did you get it out?

My mount came off pretty easily. There are 2 bolts and a nut on the engine mount, and 4 bolts (2 vertical and 2 horizontal on the bottom) on the body mount. There is of course, the long bolt attaching body mount to the engine mount.

I am assuming you have jacked up the engine enough and removed all of the bolts and nuts. Is it rusted on? A little hammer love?

George, body mount first..then the other mount is pretty easy.

OK, i didn't know i had to jack up the engine SO much, but finally it came out, should be easy now. My first FWD water pump you know.....
