I just replaced my pump last night.
2 choices from Autozone:
a) Reman with 1year warranty $21.59
b) New with lifetime warranty $26.49
Not much of a choice really
Little easier on the older NA cars. I had to remove the motor mount, but didnt have to remove any other brackets.
Draining the coolant was the only tricky part. I got creative and pumped the coolant out of the radiator with a little drill pump through the upper radiador hose opening. Couldn't go thru from the radiator cap due to the trans cooler. This allowed me to do the job without jacking up the car at all - no need to hassle with the radiator drain plug.
I would like to point out something missing from the FAQ http://www.bonnevilleclub.com/forum/...ght=water+pump
It is WAY easier to loosen the 4 little pulley bolts with the serpentine belt still on.
