Make The Conversion to Waterless Coolant More Effective ! Evans High Performance Coolant combines the benefits of Evans NPG+ and NPGR. NPG+c provides superior cooling protection for all gasoline and light duty diesel engines, including marine and light aircraft. In conditions ranging from -40 to 375F. High Performance Coolant provides cooling protection through constant liquid coolant contact with engine metals. Eliminates water-causing corrosion, electrolysis and cavitation. One successful installation provides cooling protection for the life-time of the engine, reducing maintenance time and expense. Eliminate cooling failures caused by water. Evans Waterless Coolants high boiling point eliminates pump impeller cavitation. It remains a liquid under conditions where water would boil. The absence of water from the cooling system eliminates the cause of corrosion, Evans Waterless Coolants are safe for use with all metals. No electrolysis. Evans Waterless Coolants are non-conductive. Maximize boil-over protection Evans Waterless Coolants boil at 375F, Evans Coolants wont boil over in hot weather, heavy loads, high altitude, or high power output. Evans Waterless Coolants instantly condense back to liquid state, providing constant liquid to metal contact, keeping metal temperatures under control. Increase power output and fuel efficiency. Evans Waterless Coolants allow most engines to safely operate at a higher temperature. Engines can be safely tuned for more power or better fuel efficiency. When trapped heat is eliminated from the cooling system non-computer regulate engines can operate at higher temperature increasing engine efficiency. Provide lifetime cooling performance and engine protection. Evans Coolants are non-corrosive with stable additives, no need to change the coolant or replace additives.
