Grant, one pound raises boiling point by four degrees F.
So, a 15 pound system has a boiling point 60 degrees F. on top of the std 212 degrees (at sea level)
As it happens Wartime Ford Carrier radiators are good for about 3.5 pounds.
I am running an adapter with a 4 pound cap. So far so good.
I believe there is a water wetter that has a higher boiling point than water. Is that the Prestons you speak of?

Rob. Thanks! I was thinking of you when I posted. I will look into the PH test.
It can be be done with an Ohm meter if I remember correctly.
Can anyone give us a run down on it?

Marco, I was considering the Green or Red, which apparently should not be mixed. Is one better than the other with regards water pump seal lube?
