There seems to be two parts to the water pump and the fan is what usually goes first. Olds. was smart enough to just male that part to replace only. I was replacing the alternator on my 91 and decided to replace the water pump part I was speaking of. It's cheap and easy to get to. Hope this helps in some way.

Remove the serpentine belt then remove the water pump bolts and any attached hoses. It would help to know what year, model, or engine size.
Oldsmobile didn't make a 4.3 in 2000
To change the water pump simply remove the bolts from the waterpump, pull it off and replace with new. The power steering pump will need to be loosened and moved aside to remove one bolt. Clean old gasket from engine block and replace with new gasket and replace with new waterpump.
JC Whitney and Parts Geek both carry the water pump for a 1991 Oldsmobile Calais.
