Re: 929 water pump replacement
The water pump in my Grand Am was doing the same thing to me. The bearings went bad, so for a loooong time it would rattle really bad anytime the car was running. I knew it would have to be replaced eventually, but was in no hurry to do it as it still functioned properly for cooling purposes. After about 8 months the car started to leak coolant, but I could never pinpoint where it was coming from. A couple months later, as the leak got worse, I was finally able to see it was coming from the pump itself. A quick change out made the car sound great (almost new even) and I stopped having to constantly add coolant.
The moral of the story? If it is indeed the water pump, and you have the money to replace it, just go ahead and do it now before it advances to leaking. The last thing you want is slippery arse glycol all over your back tire because it is leaking going down the road....
