Slant 6 Overheating

Yeah, that's kinda a rule I have with old stuff. If I open the cooling system for any kinda maintainance, it's gonna get a thermostat. I usually flush the system too. You might do the same. No tellin when it was done last.


Hall County, myself. But up in Massachusetts since 1984. :wack:

No, I am not worried about 1/3 gauge. Not at all! But I don't like it fluctuating. Maybe it was air bubbles. I think you were correct--it was a bad cap. Probably didn't need to do the thermostat, but it was only a half hour and $12, and now it's done.

Anyway, thanks for the tip.
