Evans High Performance (HP) Waterless Coolant is a revolutionary coolant providing dramatic improvements in heat transfer without requiring changes to cooling system components. Conversion to Evans HP waterless coolant from the use of conventional antifreeze is simple to accomplish, and offers performance advantages over water-based coolants.

Evans HP Waterless Coolant virtually eliminates boil over in gasoline or diesels - the waterless coolant allows engines to tolerate running hotter, without forming vapor, or boiling over, and allows the cooling system to run at a much lower and safer pressure. Because there is no water in the system engines operating with Evans HP Coolant will be free from corrosion and electrolysis, and the engines will run well no matter how hard they are driven or how hot or cold the environment is.

Evans HP Waterless Coolant is a long life coolant and is recommended for street use and racing where ethylene glycol use is permitted. 300 or more HP recommend use: aluminum radiator and 7 psi cap. Specified coolant for Rotax Aircraft Engines, Type 912 and 914 (series).
