Red Line SuperCool Concentrate is an ethylene glycol antifreeze fortified with the company's WaterWetter technology, so one fill covers both freeze protection and heat transfer. Red Line states it reduces operating temperatures by up to 20 degrees Fahrenheit by breaking up the vapor barrier that forms on hot metal surfaces, protects against cavitation corrosion and erosion, and cleans and lubricates water pump seals. It is compatible with new or used antifreeze of any color including DEX-COOL and long life formulas, safe for cast iron, aluminum and brass systems, and rated for 5 year / 150,000 mile protection. The concentrate must be diluted with water, and Red Line recommends distilled water.
