  • Product Information

    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.

    Engine Types

    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 use—no water required.

    • Hygroscopically absorbs water
