Evans NPG Waterless Coolant (2 Gallon (4x 1/2 Gallon Bottle))

Evans NPG is the Original Waterless Coolant. NPG 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.

Eliminate cooling failures caused by water.

Evans Waterless Coolants high boiling point eliminates pump impeller cavitation. It remains a liquid under conditions where water would boil.

The absence of water from the cooling system eliminates the cause of corrosion, Evans Waterless Coolants are safe for use with all metals.

No electrolysis. Evans Waterless Coolants are non-conductive. Maximize boil-over protection

Evans Waterless Coolants boil at 375F, Evans Coolants wont boil over in hot weather, heavy loads, high altitude, or high power output.

Evans Waterless Coolants instantly condense back to liquid state, providing constant liquid to metal contact, keeping metal temperatures under control. Increase power output and fuel efficiency.

Evans Waterless Coolants allow most engines to safely operate at a higher temperature. Engines can be safely tuned for more power or better fuel efficiency.

When trapped heat is eliminated from the cooling system non-computer regulatd engines can operate at higher temperature increasing engine efficiency. Provide lifetime cooling performance and engine protection.

Evans Coolants are non-corrosive with stable additives, no need to change the coolant or replace additives.

Cooling effectiveness and corrosion protection continue for the life of the engine. Traditional water-based antifreeze must be flushed and changed at regular intervals.

Reduced operating pressure eliminates stress and protects engine cooling components, hoses, and gaskets. Cavitation erosion and electrolysis are also eliminated.

The additives in Evans Waterless Coolants are stable. No SCAs are needed for light duty or heavy duty diesel engines. Safer for handling and the environment.

Evans Waterless Coolants are essentially non-toxic.

Evans is safer to handle during installation and engine maintenance.

Lifetime coolant helps preserve natural resources and reduce hazardous waste.
