How to rebiuld a water pump?

Question

My water pump in my pontiac bonneville 99 went bad, and while I was in the navy, in aviation fuels, some of my job consisted of repairing pumps and valves, and rebiulding them all together, and this water pump from my car seems to have some of the same features of previos pumps i've worked on, usualy when i use to repair pumps, most of the time i just replaced the bearings, just wondering if its do-able, im looking for the cheapist way to fix this, the casing for the pump seems to be in very good condition, but havent got it out of my car yet, im short on tools right now for the moment... thanks in advance for any help...

Answer 1

Dont waste your time rebuilding it, just buy one from napa or some auto parts place with a life time warrenty, on something like that your time is worth more then the water pump, and since the pump is having to deal with hot water and corrosion it's possible it might go out again soon or never but with the warrenty it wont hurt so bad.

Answer 2

Don't bother.  Water pumps fail on this motor all the time and replacements are plentiful and cheaper than dirt. I won't even use rebuilt water pumps in my shop - we only install new ones because they are much more reliable and the cost difference is literally only a couple of bucks.
