Evans NPG Engine Coolants 1/2 GAL

  • Sale
  • Regular price $27.85

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.

•Original NPG Coolant - Engineered specifically for all racing series which allow coolants other than EG based.

•For use in drag racing, circle track, motorcycles, and boats.

•Reduces System Pressure, Prevents Overheating, Maximizes BHP

Note: Evans Cooling Systems Inc. (ECS) warrants its products to be free from material defects under normal use for a period of two year from the date of purchase.

•Eliminates Overheating -Evans Waterless Coolants have a boiling point above 375°F and will not vaporize, thus eliminating overheating, boil-over and after-boil.

•Reduces Pressure - Evans Waterless Coolants generate very low vapor pressures reducing stress on engine cooling system components.

•Prevents Corrosion -Evans Waterless Coolants contain no oxygen effectively eliminating corrosion and pump cavitation.

•Increases BHP -Evans Waterless Coolants eliminate pre-ignition and detonation caused by overheating - thus improving combustion efficiency and delivering more power.

•Freeze Protection - Evans Waterless Coolants freeze below -40ºF

•Less Toxic - Evans Waterless Coolants have low toxicity.

•NPG Waterless Engine Coolant for race tracks with a “no ethylene glycols rule” and other special applications.

•Unbeatable protection against corrosion and electrolysis.

Evans NPG+C Waterless Coolant is the recommended coolant for all gasoline and diesel engines. NPG+C is a stand-alone lifetime coolant that does not freeze, or boil over. NPG+C controls detonation, cavitation, and is non-corrosive. Installing NPG+C requires the radiator, engine block and heater core to be drained completely and then filled 100% with NPG+C. NPG+C meets or exceeds both the ASTM D 1384 corrosion test and the ASTM D 3306-94 specifications.

NPG+C Technical Information:

    • Boiling Point is 375°F @ 0 psi
    • Freezing Point at -40°F
    • Viscosity - 2.3cp @ 212°F
  • Surface Tension - 44dyn/cm
