The primary objective of installing Evans waterless coolant is to eliminate many problems associated with water in conventional water-based cooling systems, while increasing reliability and engine life.
The conversion from a water-based antifreeze to Evans is a straightforward process that can be undertaken by anyone with some basic experience in engine mechanics, provided the instructions are adhered to.
An important part of a good installation is using Evans Prep Fluid. Prep Fluid is specifically formulated to purge remaining water-based antifreeze from the system after initial drain. Since certain parts of the cooling system might not drain completely by gravity, installing a scavenging fluid is the most practical method of removing all of the water-based antifreeze. The Prep Fluid is not formulated to chemically clean the engine of rust and scale, but the process of circulation and draining will help remove any loose sediment.
