I'm wondering specifically about the cooling system and the brakes. I know that Grand Prix's love to run a tad on the warm side. For example, when I climb Mt Cadillac in Maine with an 80-85 degree outside temperature, my engine gets up to about 220*, and even when the fan kicks in it stays between 205 and 210. The Cadillac auto road is about half the length of the Washington road and not quite as steep. This is something I want to do this summer, but with 230k already on the odometer, I dont want to overheat her and drive another nail in the coffin. Not that mileage really matters to our engines, but I want to avoid unnecessary abuse.
I also wonder about the brakes. I just had a brake job done in February, new pads and rotors on the front, pads on the back. I was told the brake lines were sound, no leaks, but I did not ask about brake fluid. Is it standard for a shop to change the brake fluid when a brake job is done? I know that heavy braking is bad, especially with old brake fluid which has a lower boiling point than new.
Thanks in advance for your advice, my goal is to put 300k on this car before I even consider trading in.
