It looks like the water pump and thermostat were replaced recently by the previous owner, and the thermostat housing is already leaking. I strongly suspect it was replaced with non-ACDelco parts. That is the case mostly, when parts are replaced at local garages in Canada. Usually the aftermarket parts up here are priced close to or above the price of ACDelco parts if I got them in the US. This thing can't have been in there for more than a couple of years, and now I've got to tear into it myself. I'll be putting in ACDelco parts. While it's open, I might as well change out the water pump, upper and lower rad hoses, heater hoses, and the one to the throttle body.
What a pain in the caboose.
I've had lots of bad luck with aftermarket parts. I'm posting this as a reminder to not go cheap on parts.
