I'll be taking Ol Roy's radiator to my radiator guys this week. Since it's a zero pressure system, I want to let them know but what would be the maximum pressure that that radiator could withstand?
I use a 4 lb pressure cap. So I know that it can at least take 4 lb. I just want to let them know so they don't accidentally blow up the radiator when they test it.
These days I don't take anything for granted, or that professionals actually know how to do their own job.
They're probably aren't many zero pressure systems left these days that the shop works on.
