- 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.
