Boiling point of water/anti freeze

[redls1]

Ive read so many opinions Im not sure what to think. I thought water had a higher boiling point and anti freeze was just an anti corrosive and not freeze when it gets cold. I was then told it just has better heat transfer. So what is the opinion here, should it be a 50/50 mix or more distilled water, what about water wetter or similar product and a higher psi radiator cap?

Water boils at 212F, but pressurizing the sealed cooling system raises the boiling point and along with the coolant mix is what get the boiling point even higher I believe.

Yeah that is correct. I wanna say that every 1 psi raises the boiling point 2-3 degrees. So with a 15-16psi cap the boiling point of the 50/50 mix is around 260 or so.

I wouldn't run a higher psi cap. If your cooling system is working properly the motor shouldn't get hotter than 200-230 anyway.

SSTodd is correct, also stay away from water wetter and all that Garbage. Stick with a 50/50 mix and you should be good to go.
