I just replaced my coolant with the Evans NPG+ coolant. It isn't Ethylene
Glycol based. I can't remember the kind of glycol it is but it starts with
poly(something) glycol. It is on their website but it is down for 48 hrs.
Mine was running at 250 deg. while climbing and would boil the water on a
climb. After changing to evans the temp did not change, still 250 deg on
climb and cruise at 220 deg. But now there is no boiling. This is in Florida
and it is in the high 90's right now.

The purpose of the Evans is to increase the boiling point
so there are no hot spots generating steam anywhere. In
practice the Evans conducts LESS heat and so the
temperatures recorded with Evans will be HIGHER than the
temperatures with the 50-50 Water-Antifreeze mixture.
I think !
