How to replace Water Pump

I have to replace my friends water pump on her 94' Grand Prix V6 tommorrow. Does anyone have any advice at all? I have never really worked on her car, but know a lot about mechanics in general. I just would like to know the procedure (more than take it off, take off the belt, put new one one). Thanks!

honestly, there is nothing to these. take off belt ... is about all you need to know. the hardest part about this is cleaning all of the old gasket off. besides that, there are no tricks or special tools needed or anything.
