What is Waterless Coolant?

  • Most engine coolants/antifreezes are a 50/50 mix of ethylene glycol and water. Waterless coolant is a glycol-based fluid that is ready to use, no water required.
  • Water has superior heat transfer capabilities but water’s low boiling point is close to the operating temperature of an engine, and water can cause corrosion.
  • Waterless coolants provide sufficient heat transfer, boil at a higher temperature, and are non-corrosive.
  • Installing Evans waterless coolant eliminates many problems associated with water in conventional water-based cooling systems, while increasing reliability and engine life.
  • Off-Road


    Benefits of Using Evans Waterless Coolant

  • No Corrosion: Because they remove water from the cooling engine system, Evans waterless coolants prevent water-caused corrosion.
  • No Erosion: Evans coolants remain in liquid form and do not vaporize, preventing the “pitting” caused by water vapor.
  • No Overheating: Evans waterless coolants prevent over-boiling by raising the boiling point of antifreeze from around 226°F for water-based antifreeze to 375°F—far about the operating temperature of an engine.
  • No Electrolysis: The absence of water in Evans Waterless Coolant, substantially reduces electrical conductivity of Evans coolant which sharply reduces incidents of electrolysis.
  • No Pressure: Because Evans coolants remain in liquid form, they prevent stress on cooling system components such as hoses, pump seals and radiator seams due to high water pressure.
  • How does Evans help stop coolant change-outs?: Evans has always contended that the absence of water in a cooling system removes the root causes of metal corrosion, electrolysis, and high system pressures.
  • Which Evans Product Should I use for my Vehicle?

  • High Performance Waterless Engine Coolant: For cars, and light duty trucks. Also for use in boats, light aircraft, light duty diesels, LP and CNG engines.
  • Heavy Duty Waterless Engine Coolant: For all heavy duty applications such as class 8 trucks, generators, and offhighway equipment.
  • Waterless Powersports Coolant: For use in motorcycles, ATV’s, snowmobiles, and other off-road powersports applications.
  • NPG Waterless Engine Coolant:For racing venues that allow propylene glycol based coolants, but not ethylene glycol based coolants. Not for general use. Adaptive equipment may be needed for specific high performance applications. Call Evans Cooling Systems for further specifics regarding use of NPG.
  • Prep Fluid: Used as a waterless flush to remove remaining water-based coolant from the cooling system prior to installing Evans waterless coolant. Prep fluid is 100% compatible with all Evans waterless coolants.
