How long does the Water Pumplast?
Mine lasted 100k miles, I was surprised. I wasn't paying attention and it started to leak and destroyed my Opti. Just make sure if it starts to leak to change it ASAP or you'll be FUBAR. It's alot cheaper to get just the H2O pump for 150 then the pump and another 400 for the Opti.
Mine was done at about 40k, but even though it leaked, it never caused the engine to run any hotter. I would bet your problem lies elsewhere.
If your pump is not leaking out the weep hole, it's probably ok for now.

While installing Jet-Hot LTs on my car last weekend I noticed that the water pump weep hole shows signs of drainage. The car has 94k miles and running the original pump. The weep hole isn't wet or dripping at the moment so my guess is that it is leaking when the engine is running and stops leaking when the engine is off. I'm changing it tomorrow while finishing up my LT install...just to save my Opti (which is original too).

. Seriously though... it'll take the Opti with it if you wait untill it goes out.
I just finished removing the second one at 60K due to a new opti and CSI install.
