Default Re: Bending Overflow Tube

Seal closed the overflow tube,run a pressure type radiator cap with a relief type tube and neck..its pretty simple.The results are a different story,pressurizing raises the boiling point. On a model A raising the boiling point is moot,160 degrees being the optimum temperature.Like any repair,find the root cause of your issue,don't 'mask' it..fix the cooling system before you allow more heat capacity.
