Evans Waterless Coolant PREP Fluid – 1 Gallon

Product Details

When switching to Evans Waterless Coolant – it is necessary to make sure your system contains <3% water post-conversion.

Evans Prep Fluid is a Hygroscopic waterless cooling system flush designed to remove any remaining water left after draining all conventional anti-freeze and water from your BMW’s engine. Evans Prep Fluid should be used to complete a successful conversion to Evans coolant, but it is not a substitute to a thorough drain of all cooling system components via a block drain. Evans recommends running Prep Fluid through your cooling system before refilling with Evans High Performance Waterless Coolant to ensure your water content is below 3% (54.4 Brix). This can be tested with an Analog Refractometer: T#553530

Features:

Properties: Hygroscopically absorbs water.
When to use: After draining 50/50 coolant from the cooling system.
Benefits: Ensures all residual water is removed from the system.

NOTE: Prep Fluid is not to be used as coolant. This product flushes water out of your system to successfully convert to Evans Waterless Coolant.
