EVANS Coolant EC10064 NPG Waterless Engine Coolant, 64 fl. oz. (EC42001 EC10064 Combo)

Evans NPG Waterless Coolant is specifically designed for Racing venues that allow propylene glycol based coolants, but not ethylene glycol and food service equipment where ethylene glycol products are contraindicated. Evans Waterless Coolants have a boiling point above 375 Degree Fahrenheit and will not vaporize, eliminating overheating, boil-over and after-boil, while generating very low vapor pressures reducing strain on engine cooling system components. Contains no oxygen, effectively eliminating corrosion, liner and cooling pump erosion, resulting in reduced maintenance costs. Eliminates pre-ignition and detonation caused by overheating, reducing downtime, improving combustion efficiency, and delivering more power. Provides low temperature freeze protection with a freezing point below -40F. Evans NPG is the Original Waterless Coolant and is a lifetime coolant. NPG is recommended for racing engines that run on tracks or in series where there is a "NO Ethylene Glycol" rule, and can be used in high performance street vehicles with high flow cooling systems. NPG is NOT recommended for daily drivers or cold weather operation, and may require system modifications to ensure a successful conversion. Evans Prep Fluid should be used to ensure all residual water is removed from the system before adding Evans Waterless Coolant. Evans Prep Fluid is a waterless cooling system flush designed to seek out remaining water after draining the cooling system of an engine. Prep Fluid should be used when block drains are unavailable or cannot be removed. It is not a substitute for thoroughly draining the cooling system and related components. A minimum of 2 gallons of Prep Fluid is recommended for heavy duty diesel engines and 1 gallon of Prep Fluid is recommended for all motorcycles converting to High Performance Coolant or Powersports. Prep Fluid is NOT intended to be a stand-alone operating coolant, but as a flush only.
