somethings not right here
Bill don't beat yourself up, remember this: There IS (was) a way. Many of us had BB/ RB cars "back then" and THEY didn't overheat. My V code 70 RR was a sixpack, later had a Sig Erson in it and IT did not overheat in San Diego/ LA traffic.
The other thing is "is it puking water?" If not you might be "over worrying" a bit
