Water-based antifreezes have been used in car engines for about a century, but water can cause major problems inside engines, including corrosion, boil-over, and engine breakdowns.

Evans Coolant meets ASTM specifications for waterless coolants for Light Duty Service. ASTM D8085 – 17 is the ASTM standard specification for Non-Aqueous Engine Coolants for Automobile and Light-Duty Service. .
