1997 Pontiac Grand Prix GTP Question: Coolant Leak
I've been having a couple problems since the winter rolled around. Coolant is leaking and I can't find the leak anywhere. It's over heated twice. I can't even drive it a mile down before it starts to over heat. this is after putting more coolant in. I'm also noticing a strange whirring coming from my belt and I think that needs to be changed too. Any idea about repair costs for either problems and what to do in the meanwhile about overheating. I don't know much about cars, but I got this Grand Prix in June and I think the previous owner may have purposely over-looked some issues when selling it to me. I do love this car though - Crescentisalive

The water pump may develop a coolant leak resulting in an engine overheating condition.
