Evans NPG waterless coolant, available in a half-gallon bottle, is recommended for racing engines that run on tracks or in series where propylene glycol-based coolants are allowed but there is a “No Ethylene Glycol” rule.

NPG can be used in high performance street vehicles with high flow cooling systems, as well as for food service equipment where ethylene glycol products are. If you are planning to use NPG and NOT HP the pump volume does need to be higher then if using HP due to the higher viscosity of the NPG coolant. Radiator design and restriction( hose size, restrictor size) become more important when using NPG in a electric pump system.

In their advertising, Evans makes the claim that Evans NPG Coolant can maintain a substantially vapor free liquid to metal contact (nucleate vapor only) at all coolant temperatures and engine loads.

The coolant creates a higher boiling temperature for the water, providing you with a. The company I work for tested Evans coolant in a pair of our Mack trucks.

I did the conversions and it was crucial that ALL the water was removed from the system. They gave us a special refractometer to test the coolant to make sure there was no water in the new coolant after the conversion. I had to drain out the new coolant once and refill again with new before it tested good. While anyone servicing a cooling system must remain cautious around hot liquids, the danger of an explosive discharge of coolant from accidental cap removal or component rupture is minimized.

The Duc has used Evans NPG -R coolant for last 5k miles. That is the only noticable change I have experienced.

My temp guage indicates coolant temp to be essentially the same under normal operating conditions. Heck the detonation. By contrast Evans NPG coolant is non-corrosive to the cooling system and because Evans NPG coolant contains no water all of the problems associated with water in the cooling system are eliminated.

After a fresh engine rebuild is an excellent time to add Evans NPG coolant to the engine and cooling system. You will have a lifetime of engine.

My 1has a history of cooling system problems : replaced radiator, heater core, pump, etc. The head on the 1is also sensitive to overheating.

If your cooling system is not working properly the EVANS coolant is not going to fix things. Matt Harwood and motoringicons have obviously done their homework and have covered many of the advantages.

Yes, the waterless coolant does boil at a much higher temperature. The only thing to look out for is not to leave it in the system too long.

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 System.
