About a year ago I noticed I was loosing radiator fluid. I couldn't find the leak and it was minor, about 12 ounces a month, so I let it go and just topped it off. Well the leak finely started to get worse. I still can't locate where it's leaking from so i decided to start with the pump itself. With just over 177,000 miles on the original pump I thought it could use replacing anyway. I think the gaskets were my leakers, the o rings weren't attached to the metal gaskets at several spots. The pump itself looked to be in perfect shape yet. How many miles have you all gotten on your original water pump?
 
Still on my original from 2001 and has about 165kish miles.
 
You guys are lucky.

I replaced my water pump at 65,000 miles the first time. I bought the AC OEM replacement from Rockauto and it failed within a year/10,000 miles. Fortunately I caught it on day 364 of my one year warranty and Rockauto replaced it. The next AC OEM pump failed after 65,000 miles again. I went with a Gates water pump this time.

Mine just went out recently on my 2004 at 158,000.  Replaced it with the AC OEM pump.  Crossing fingers.
 
Water pump on the wife's traverse went out in May at 179k miles. I smelled an ever so faint hint of coolant when the motor was out and the garage door closed for a few months before it gave out. The avalanche is still (assuming) original at 130k.
 
I'm not certain how old the water pump is in my 233K mile EXT.

But I know it is the one that was in the truck when I bought it with 116K on it.

Maybe I'm due.
 
I bought a gates water pump, the upper hose connection wasn't clocked correctl;y, the hose wouldn't go all the on because it ran into the front component of the intake. I went to autozone, I bought the 1 year warranty pump, same problem, took it back and they ran he P/N on the OEM pump and came up with a Duralast pump, it's water spout was clocked about 2 degrees so I made it work. Be careful on those water pums guys...
 
I went with the GMB water pump from Rock Auto last March. So far so good. Previous was a AC Delco It lasted 6 yrs. and 70K miles.
 
For about 8 months prior to the failure I had a faint smell of coolant out of the front engine (walking around the truck after driving it) was the only way to detect it. Leak was very small, could not find where it was coming out and over course of the 8 months had to top off the resevoir once.

Then one day, no heat and resevoir below the low level.
