Evans Prep Fluid is a waterless cooling system flush engineered specifically to purge the cooling system of water-based antifreeze after draining and before installing new waterless coolant. 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. Prep Fluid is NOT intended to be a stand-alone operating coolant, but as a flush only.
For use with all engines being converted to any Evans waterless coolant, after draining 50-50 coolant from the cooling system.
Evans Prep Fluid is ready to useno water required.
- Hygroscopically absorbs water
- Ensures all residual water is removed from the system
- Ensures that Evans coolants will meet the water content limits and provide peak performance
- Protects cooling system metals during flush
To ensure success using Prep Fluid to prepare your cooling system for Evans waterless coolants and to determine the amount of Prep Fluid needed, follow the recommended installation procedure.
