Why Griffin Recommends Evans Coolant 

Evans Waterless Coolant provides distinct advantages over traditional water-based coolant. The absence of water avoids the formation of vapor, high pressure and boil-over, and prevents corrosion and electrolysis. Evans’ high boiling point and lower freeze point allow a wider and safer operating temperature range. The benefits derived from Evans can be achieved in most vehicle applications and engine types, although Evans’ performance may vary depending on cooling system configurations.

The Benefits of Using Evans Waterless Coolant

Evans high boiling point virtually eliminates vapor in the engine, ensuring constant liquid-to-metal contact. Evans draws more heat from the engine, which may lead to slightly higher coolant gauge temperatures (by 10 to 20 degrees). Heat management is improved as engine component temperatures are kept under control.
Lower Pressure: Evans’ lower system pressure reduces stress on hoses, seals and gaskets.
Corrosion Protection: The absence of water also means no corrosion and electrolysis. This is particularly important for cars stored for long periods of time.

What is the Right Coolant for my Use?

High Performance Waterless Coolant: Cars and light duty trucks. Heavy Duty Waterless Coolant: Heavy-duty diesel trucks, and off highway equipment Powersports Waterless Coolant: Motorcycles, ATV's, UTV's, and snowmobiles.

How Much Coolant will I Need?

EWC is a stand-alone coolant, not to be mixed with water. You need enough to completely fill the entire cooling system. Check your owner’s manual for coolant capacity.

How Much Prep Fluid do I Need?

If you cannot fully drain the system; Open the lower radiator hose and block drain plugs if accessible, and heater core. Allow to empty and force high volume air to purge remaining coolant. Fill with Evans Prep Fluid, run the vehicle to circulate and drain again. This would require approx. 75% of the system volume of Prep. Alternately, smaller quantities of Prep can be used to flush through a component, or plumbing.

Will I Need to Use a Chemical Flush or will Prep Fluid be Sufficient?

For neglected cooling systems or high mileage vehicles, a chemical flush may be necessary to remove rust, scale and residue prior to using Prep or Evans Coolant. Evans offers a Cooling System Flush for neglected cooling systems.

Will Evans Lower my Engine Temperature?

Typically, no. Vehicles running under normal operating conditions should show either no change or a slight increase in temperature, but that will depend on cooling system configuration as well as driving conditions. Certain systems that use incompatible components, have an existing problem, or are poorly designed could run hotter. The ability to lower the operating temperature depends on multiple factors, primarily coolant flow volume and air flow temperature. For example, multi-pass radiators will result in higher temperatures due to decreased coolant flow volume vs. large tube multi row radiators that improve coolant flow. Different thermostats may increase flow volume because of less restriction. Water-based coolant boils at a temperature only slightly higher than the operating temperature of the coolant. Localized boiling releases water vapor that can only condense into coolant that is colder than the boiling point of water. Vapor that doesn’t condense occupies a volume that displaces liquid coolant. Hot engine metal, insulated by water vapor, becomes an engine “hot spot” that can cause pre-ignition and detonation. Evans’ high boiling point means it will not turn to vapor.
