Default Re: Bending Overflow Tube

I do not understand why increasing the boiling point in a Model A is desirable. Boiling/steam is a warning that your cooling system is running too hot with possible oil flash-over at the cylinder walls. By increasing the boiling point you increase the chance of running beyond being safe, beyond what was designed. Modern cars with pressurized systems are designed for the hotter temps.

Correct me if i misunderstand.
