How do you replace the water pump on a 1998 Oldsmobile Aurora V8?

Answer 1

I recently replaced the fuel pump on my '97 with the 4.0 V8 and I would guess that the procedure is the same. First I went to the public library, found a repair manual, and photocopied the appropriate sections. After removing the hoses, belt cover, belts, etc. you'll get to the pump. The pump is strictly the impeller and pully wheel. I spent about $50.00 at NAPA for my unit. You will, however, need a special Cadilac/Buick/Olds removal tool for the Northstar engine. GM prices run from $100 to $180.00 on this tool. However, you may find a tool rental shop with the unit, so make a few calls. I ended up purchasing the too from a MATCO Tools distributor for $26.00. It worked and I'll probably never need it again, but $26.00 is much better the $100.00. After replacing the pump, replace everything else per the manual innstructions. The job goes rather quickly when you have the right tool. Hope this helps.
