Evans Waterless Coolant
Also known as Race Fluid, NPG-R is one of Evans newest waterless coolants. NPGR is designed for use with high performance vehicles, race cars, motorcycles, and other power sports vehicles. It is Evans' best fluid for transferring intense heat from hot cylinder heads of high performance engines to radiators because of its better heat conductivity and lower viscosity, while providing a huge separation between the operating temperature of the coolant and its boiling point. It can be used without any changes to the cap, the radiator, the pump, or any cooling system components. For racing, it is recommended that NPG-R be replaced at the end of each racing season. Evans NPG-R has a 5-year maximum life for other purposes.
