What is the flash point of Evans coolant?

The flash point (the lowest temperature at which a combustible substance produces sufficient vapor near its surface to generate an ignitable mixture with air) of Evans waterless coolant is similar to that of conventional water-based coolant, i.e., 248 °F/120°C.

Over time, will Evans coolant absorb water?

Evans waterless coolant is hygroscopic, which means it has the ability to absorb moisture. As such, containers of unused coolant should be kept tightly closed. In the cooling system, Evans waterless coolant should not absorb a significant amount of moisture from the atmosphere as long as a conventional pressure cap is used. Under normal circumstances, the cap should not open, allowing air to enter the system.
