Running without a thermostat ok?

thanks for the input on that. I never had heard of that before, but i'v e also forgot half what I did know!???? LOL
for the guys like me that can't afford a new rad, alum or oem type, maybe this 7# cap would be something to consider on these ancient radiators!!!!
and that shop pressure tested and repaired 2 rads for, I think it ,like $30 total!!!!! good guys and bargains still exist!!!!
o k. I've had my snack, rested my old arm, back to blocking that primer!
