Boiling point of anti freeze
I flushed and refilled my trucks radiator today. I noted on the bottle that a 50/50 solution of antifreeze/water will result in a 256 degree boiling point. This piqued my curiosity so I did a little...

Cooling system is a closed system under pressure....lets use your 15 psi.
At sea level or 8000 ft it is still 15 psi in the cooling system. Should be the same boiling point high or low altitude.
Not quite. The cap raises the pressure above ambient sea level air pressure (14.7 psi). At 8000 MSL the ambient pressure is about 4# lower than sea level.
That’s why water boils at 198 degrees at 8000 msl.
Isn't that lower boiling point at altitude measured using water in an open vessel, then being heated to the boil?
