How do I repair/replace a water pump for a '99 GMC Sonoma? I'm leaking water

[meyerjd2000]

like a runny faucet ? It's been slowly leaking for awhile now, but today it dumped brown water out like a bucket, when I shut it off facing up hill.

water pumps last less than 100k miles, get a replacement pump ,it should come with a gasket set. you may need to removed the fan shroud. Remove the serpentine belt (remember how it went on!) unbolt the old pump,you'll loose a lot of fluid ,so don't let Fido drink it. Now reverse the process and don't loose any bolts or drink beer while your doing this!The brown stuff you saw, was water .be sure you refill with coolant or the seals on your new pump are gonna get thrashed. Good luck kid.
