Hmm...I might as well just drain and refill the whole system, then. I have no idea how long that stuff's been in there, so it should be changed anyway, and draining it all out the bottom before I start will minimize spillage when I open the thermostat housing.
I wouldn't have asked at all except for a minor brain fart. For some reason I'd misread the capacity given in the manual as 12.5 *gallons*, which is way more than I wanted to deal with, but in hindsight there's just no way it could hold that much. ;)
