To take advantage of all the benefits of Evans Waterless Coolant, Evans recommends ensuring your system has <3% water remaining in the system - Prep Fluid is designed to help achieve this.
Evans Prep Fluid is a Hygroscopic waterless cooling system flush specifically engineered to seek out remaining water after draining conventional anti-freeze and water from an engine. When block drains are unavailable or cannot be removed, Evans Prep Fluid should be used to complete a successful conversion to Evans coolant. Prep fluid is not, however a substitute to a thorough drain of all cooling system components, including the heater core and radiator. Evans recommends filling your system with Prep Fluid, running it, then drain and fill your system with Evans Waterless Coolant. Once complete, you can check your water content with an Evans Analog Refractometer: ES3524598
