Hey Ernie,

Yes, you are correct that the boiling point will indeed be lower, but at the same time, could you imagine the air being sucked in to and circulated through his cooling system by not having the system closed and pressurized. At the same time, the overall thermodynamics of the coolant (no matter what the coolant is) will be effected by the inherent hot spots located within the engine itself. Trapped air within the system will cause the same results as what JLW posted above. Sometimes overlooking the simple things, and over analyzing the current results will cause more of a headache than there needs to be.
