I don't know that the hoses have ever been replaced. Unless they are collapsing while I'm driving (and can't see it) they are fine. Checked them while reving the engine and setting idle...

Isn't that right Bessesen2! Love our Grand Prix. Sexy car with muscle and dang good gas mileage! It's been a great car with very few problems. With as many miles as it has on it, I'd say we've definately gotten our money worth out of the old girl. I know she'll still be a good car if we can just figure out this overheating issue...
