Zero pressure cooling system

[Magard]

I'm interested I zero pressure cooling system. I've done this before on older equipment but it was my understanding that pressure raises the boiling point so you don't have [ I'm not sure what you call it but liner errosion from boiling points.] does coolant its self raise the boiling point high enough to stop this. If it does than why run with pressure it seems to create problems and stress on the system.
