Re: 120 advise

Your temperatures sound normal for my 1938 120 (1602) with the optional warmer thermostat (used to improve fuel efficiency/mpg). However, some thermostats have no vent hole to reduce minor boil over or burping of gases, air or localized steam on stopping.
So a solution is to drill a ~1/8" dia hole in the thermostat flange. This I have done with success. Of course if I overfill the radiator it burps!
