Our engines are designed to use a pressurized cooling system. What happens when you try running them without pressure? 
Is the water pump going to circulate the coolant through the entire engine the same way and at the same rate?
My horrifically expensive engine with an intercooled supercharger isn't about to become the lab rat on this one.
I honestly do not think it would harm the engine. Now for under pressure, is the coolant pump not belt driven? That would be what circulates the fluid. The representative made a comment that you could open the cap while the engine was hot. I doubt they would engineer a fluid that is harmful to an engine. Most modern day cooling systems that run water/glycol are pressurized any ways are they not? Pressure is just a by product of the water mix in the system, is pressure really necessary, especially if there is a better fluid that does not create it? Good question for Evans. I am sure a quick call to their Corporate/R&D in Sharon, CT might have the answer!
