There are six allen head bolts in the face of the pump. The four at 12/3/6/9 o'clock take it off the engine, the other two (10/4 o'clock) hold the front face on the main block.
Remove the steel return line into the top of the reservoir and with a short hose, aim it into a plastic bottle (2L Soda bottle works fine). Start the engine and let the pump empty the reservoir into the bottle. Loosen the big 10mm bolt for the AC Pump idler pulley so it can be lowered out of the way, then take off the inlet and outlet lines from the pump.
Remove the four bolts and remove the pump. Remove the two bolts and open up the pump - keep everything clean!!
Remove the big o-ring, remove the center shaft of the pump, pry out the shaft seal in the back and then gently hammer in the new seal. Lube the shaft and gently push it through the seal, install the new o-ring, bolt the face plate back on. Scrape off the baked on paper washer from the back of the pump. I used some silicone gasket material spread on the rear face to hold the paper gasket in place whilst reinstalling the pump.

In progress - FrankenBenz SEC: GM LS6 5.7L engine with custom 4L60E 4-spd overdrive transmission, GM rack and pinion.
One of my goals with the FrankenBenz is to scare women and children, and to have Lexus drivers spill their latte.
