Water-based antifreezes have been used in car engines for about a century, but water can cause major problems inside engines, including corrosion, boil-over, and engine breakdowns. Waterless coolants can prevent engine overheating and reduce cooling system maintenance, and can last much longer than a water-based coolant.
Most engine coolants/antifreezes are a 50/50 mix of ethylene glycol and water. Waterless coolant is a glycol-based fluid that is ready to use, no water required.
Water has superior heat transfer capabilities but water’s low boiling point is close to the operating temperature of an engine, and water can cause corrosion.
Waterless coolants provide sufficient heat transfer, boil at a higher temperature, and are non-corrosive.
Evans is the only manufacturer of waterless antifreeze.
Installing Evans waterless coolant eliminates many problems associated with water in conventional water-based cooling systems, while increasing reliability and engine life.
