Thanks guys. I'd planned on borrowing a pressure tester shortly (have a friend in the radiator business), but with a whiff of coolant at the water pump, I'm pretty sure that's the problem.

215,000 miles and I don't know when it was replaced last, not bad.

As I said, now is the time since I gotta take everything else off anyway.
