What is an Evans Waterless Coolant?

Evans Waterless Coolants are the ONLY 100% waterless automotive engine coolant available on the market. All Evans Waterless Coolants are a chemical blend that results in more efficient cooling due to a higher boiling point. The increased boiling point of the coolant eliminates the occurance of boil over, cavitation, and detonation. Not only do Evans Waterless Coolants not boil over,they do not freeze. At extreme cold temperatures the coolants contract and become extremely thick, not becoming solid and expanding like antifreeze containing water. Because Evans Waterless Coolants do not contain water electrolysis and corrosion are also eliminated. Every Evans Waterless Coolant requires the entire cooling system to be drained (radiator, engine block and heater core) and refilled 100% with one of the Evans Waterless Coolants. No need to add anything. Evans now has three different coolants to choose from depending on the application and use of your specific vehicle. Also available is a flush fluid for smaller engines without block drains.


Evans Heavy Duty Coolant

Heavy Duty Coolant

Evans waterless Heavy Duty Coolant boils at 375° F. In use, it features a huge separation between the operating temperature of the coolant and its boiling point. Heavy Duty Coolant can therefore control metal temperatures at coolant temperatures that are well above the boiling point of water. With engine metals protected at higher coolant temperatures, fan turn-on temperatures can be safely increased. Evans has found that raising the fan temperature to about 230° F can decrease fan-on time over 50 percent. Engine and truck builders often use giant radiators and amazingly powerful radiator fans for the sole purpose of keeping water-based coolants cold enough to remain functional. Released from the burden of avoiding the boiling point of water, Heavy Duty Coolant waterless coolant enables the safe use of higher coolant temperatures and sharply reduced fan usage.  Thousands of dollars in fuel savings annually result from that technique.

Evans Automotive


Evans High Performance Coolant (previously known as NPG+C)
Currently formulated for use in all gasoline internal combustion engines and light duty diesel applications; Evan High Performance Coolant, provides year-around protection and the best heat transfer characteristics.

For all previously converted vehicles to Evans Waterless Coolants, this new High Performance formulation is a combination of the best benefits of both NPG+ and NPG-RACE.

All Evans waterless coolants are compatible - therefore for applications previously installed with either NPG, NPG+ or RACE all can safely be topped off with the new High Performance Coolant (NPG+C).

For technical assistance for your specific aplication, you may contact Evans directly 888-990-2665 or by contacting a stocking dealer.  Dealer list can be accessed under the Automotive Tab or under the Products Tab on this website.

Evans High Performance Coolant combines the benefits of Evans NPG+ and NPGR. NPG+c provides superior cooling protection for all gasoline and light duty diesel engines, including marine and light aircraft. In conditions ranging from -40˚ to 375˚F.  High Performance Coolant provides cooling protection through constant liquid coolant contact with engine metals. Eliminates water-causing corrosion, electrolysis and cavitation. One successful installation provides cooling protection for the life-time of the engine, reducing maintenance time and expense.

Evans Powersports Coolant

Powersports Coolant

Evans Powersports Coolant offers improved performance and reliability. Even under extreme conditions, Evans Powersports Coolant will not overheat. Using Evans Coolant allows the engine to be safely tuned for more power. A higher compression ratio, leaner mixture, and more advanced spark are some of the options available to the engine builder. Evans Powersports Coolant provides permanent cooling protection for the life of the engine so replacement is never necessary. Its superior corrosion protection is not degraded over time and it won’t freeze or damage engine components.


Evans Prep Fluid

Prep Fluid

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.


Evans NPG


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.
