EVANS BUNDLE Analog Refractometer E2196 + EC41001 Prep Fluid 4 Pack | Flush Old Water-Based Coolant from Engine to Prepare for Waterless Coolant Conversion | Accurately Test for Residual Water Content

Evans Prep Fluid is a waterless cooling system flush designed to seek out remaining water after draining the cooling system of an engine. 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. A minimum of 2 gallons of Prep Fluid is recommended for heavy duty diesel engines and 1 gallon of Prep Fluid is recommended for all motorcycles converting to High Performance Coolant or Powersports. Prep Fluid is NOT intended to be a stand-alone operating coolant, but as a flush only. Evans Coolant contains a bittering agent/bitterant. The Evans Cooling Refractometer is designed to accurately test for residual water content. By determining the water content you'll be able to safely set up your cooling system with Evans Cooling products. Pre-calibrated for accuracy! Fast, simple optical method. Requires only 1 drop of coolant. Evans analog refractometers are used to measure the final water content after a conversion to Evans waterless coolant using a Brix scale.
