Dunno exactly, although the thermostat was replaced last month. Would that have necessitated a coolant flush? The coolant looks a-ok.

I should add that this problem surfaced about six months ago, and it's been sufacing again and again despite my mechanic's efforts. Since the aux fan does not work at all, I'm likely to suspect it as the cause of the problem. But what do I know?

Thanks for the help.
If you have the PO's repair records, you know when the water pump was replaced.

Does your car have a timing belt, which needs to be replaced at regular intervals 50,000-60,000 miles? If it has that belt and you don't have repair records I'd be worried about that. The good news is it's in the same area as the water pump and you can replace both at the same time.
