Evans Waterless Coolant Installation Instructions

July 2018

Due to the variety of equipment and cooling system configurations, only generic installation procedures are

provided in this document. Specific information is available for some vehicles and engines at

www.evanscooling.com. Thoroughly review these instructions before starting your installation of Evans

Waterless Coolant (EWC).

Also, at the beginning of the installation process, have on hand enough supplies of the appropriate EWC

(Heavy Duty, High Performance, Powersports, or Arctic) and Evans Prep Fluid to complete the project. See

your owner’s manual for cooling system capacity.

When converting an engine from a water-based coolant to EWC, great care should be given during the

installation (conversion) process to insure that all of the old water-based coolant is removed before installing

new EWC. When the conversion is complete, the water content of the fluid should be no more than 3% to

take best advantage of the waterless coolant technology.

SPECIAL CONSIDERATIONS

1. WATER CONTENT: As stated previously, the water content of EWC after installation should not

exceed 3.0%. The existing water-based coolant must be completely drained from the system. It is

recommended that Evans Prep Fluid be used to absorb and remove residual water and coolant

after draining the system. Water should NOT be used to flush the system after draining the coolant.

The sole exception is if the system requires chemical cleaning prior to coolant changeover. See next

section.

2. COOLING SYSTEM CLEANERS: New EWC should not be installed into a dirty system. If the system

or the drained used coolant shows signs of contamination (oily film, rust or sediment, etc.), a chemical

flush should be performed. Follow the cleaner product instructions closely. The system must be

thoroughly flushed with water after using the cleaner. Keep in mind that flushing with water makes

residue that is 100% water. (Residual 50/50 coolant is only half water.)

3. SCA’s/COOLANT FILTERS: Evans waterless coolants are not intended to be used in conjunction

with supplemental coolant additives (SCA) or extenders. Chemical filters used in heavy duty

applications should be replaced with non-chemical filters prior to installation of EWC. No additions

of any kind should be made to the system with the exception of topping off the system with

new waterless coolant. If compromised by addition of other coolants or fluids, including water, a

coolant replacement should be performed.

Because EWC tends to remove old cooling system deposits which are then trapped by the filter, the

filter on higher mileage vehicles should be inspected monthly and changed as needed until they

appear essentially clean.

SPECIAL EQUIPMENT 1. A high-volume air source (rather than high pressure) If compressed air is used to help remove the old coolant and water, be aware that it can damage cooling system components. The use of high volume, low pressure air is preferred because it is safer, and in most cases, more effective. Recommended air sources include the Makita UB1103 hand-held blower, or a clean, powerful shop vacuum cleaner, used in the blower mode.

• Engines having an “inlet side” thermostat and a good block drain (e.g., DD15) do not require removal of the thermostat. With the block drain open, air blown toward the engine through the top radiator hose will purge the residual coolant in the block. • Completely empty the overflow bottle if the vehicle is equipped with one. If the system has a pressurized expansion tank, blow air into it to make sure it is empty. 2. Purge the System: • Close all drain valves, plugs, and vents, and reconnect circuits.

MIXING COOLANTS Waterless and water-based coolants should not be mixed. In the event that significant waterless coolant is lost from the system during operation and no waterless coolant is available to fill the system and reach a repair facility, water-based coolant or water may be used. However, repairs should be made as soon as possible, and the system should be drained, purged and re-filled with new waterless coolant. STOP LEAK USE Stop-leak type products are not recommended to repair leaks.

APPENDIX 1 DETERMINING WATER CONTENT OF A WATERLESS COOLANT Evans Refractometer Part# E2196 Use for Reading Water Content of Waterless Coolant • Readings are temperature sensitive, so calibrate before each use: Calibrate the refractometer by placing a drop of new Evans Waterless on the refractometer glass. Use the small screwdriver supplied with the instrument to turn the calibration screw until the boundary between the upper blue field and the lower white field meet at 57.0.
