hrm, well should i tell the service dept. they are wrong? I told them the symptoms, overheating etc.
I barely made it to the dealership w/o the temp gauge going into redzone....
if the impeller broke, would it make noise?
Did you authorize the repair yet? I seriously doubt that they are correct in their diagnosis. Ask them specifically whether they checked the operation of the water pump, and not just that it's not leaking and the pulley turns on the outside. Why do they say the thermostat is bad? If you're in the red and there's no heat, the water pump is 99.9% likely shot.
I replaced mine as preventative maintenance and it was like 2 hours, but I was slow and careful and spent nearly one hour scraping the old gasket off - pull the entire pump out (disconnect the 2 hoses attached to it) and it'd be a lot easier to do that part of it. I'd be inclined to pay them their diagnosis fee and change the pump for the NAPA metal impeller one if I were you.
