I wrote my previous, without 'bothering' to read 'my' attachment. I hope ya'll took note of the following paragraph, therein: "Due to its high boiling point, NPG coolant doesn't need a pressurized cooling system to suppress boiling. A closed system is recommended, as NPG attracts atmospheric moisture, & a closed system prevents that, & helps coolant containment." "It" goes on , to say that 4 -5 lbs pressure-caps are used by some people, but that "many" people report perfectly-fine performance from an un-pressurized system. And, the boiling point is : "369 F ", and, the slightly-higher operating temperatures are favorable, to the engine, and to MPG (!!!!). Think Horace will like this, too! It's nice not to be hosed.
