1931 shutter spring

Posted by Greenfield On 2021/4/11 8:14:57

I've got pull my radiator/shutters apart as I apparently don't have a spring to assist closing the shutters. Am I correct that the tension of the spring should be just enough to pull the shutters closed? Or is the tension even less than that?

Also, are the shutters attached to the radiator shell or the radiator itself?
