Losing coolant

[Don Bradner]

My parts list calls the tank a "Deaeration" tank. Presumably that's because any
air bubbles in the system will tend to eventually rise to the highest point and
depart from the fluid.

I would normally call it an expansion tank, as it has considerably more room for
fluid to expand into than the top of the radiator normally would.

As far as cap poundage goes, I would argue that the point in our engines is not
so much to do with raising boiling point, since the coolant is supposed to stay
well below even the boiling point of water, but rather just to keep the system
"closed" under normal circumstances.
