here is a boiling point chart for water.
I have been thinking about how I plan to go with my coolant system. One thing I was looking at is water swell. For the swing from 32 to 212F, the water volume will increase about 5%. I believe the Pantera system holds 28 quarts so that means the tank air volume needs to be about 1.4 quarts
edit;
does any one know the volume of the over flow tank?
just a quick though, the free volume in the over flow needs to be about twice of the coolant swell to limit the air space pressure to ~15 psig.
