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.
