Evans Prep Fluid


Evans Prep Fluid is a waterless cooling system flush engineered specifically to purge the cooling system of water-based antifreeze after draining but 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 use, no 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
