Evans Cooling Systems Inc.’s Arctic coolant in now available in gallon-size containers. Designed specifically for use in environments as cold as -60°F, Evans Arctic waterless coolant will not damage radiator tubes or cause blocks to crack because it shrinks when it solidifies at temperatures below its -60°F freezing point, according to the company.

Evans noted that it tested and demonstrated its ability to perform at both ends of the temperature spectrum at the Iron Dog snowmobile race in Alaska last February, where temperatures reached below -50°F.

With Evans waterless coolant there is always a huge separation between the operating temperature of the coolant and its high boiling point (375°F), said Evans. Vapor does not form in the coolant jacket as it can with water-based coolants. The metal surfaces are always in contact with liquid coolant, so metal temperatures are always under control, added Evans. Evans’ technology can also lower maintenance costs, improve performance and reliability, and offer superior protection against corrosion and electrolysis, according to the company.
