Evans Engine Coolants

Evans Engine Coolants

A unique range of non-toxic waterless coolants suitable for internal combustion engines. Evans coolants are proven to overcome the problems and limitations associated with water-based coolants.

Water is an excellent fluid for cooling whilst in a liquid state, but when water turns to steam it has virtually no capacity for heat transfer. Evans is a superior fluid for transferring heat in engines because it remains in a liquid state until above 180°C. This article details the benefits of a significantly higher boiling point.

Within an engine cooling system the hottest surfaces are those adjacent to the combustion chamber, specifically the cylinder liners and cylinder head. In these hot spots water is likely to vaporise preventing efficient cooling and causing loss of performance and unnecessary engine damage. When the coolant fails in this way the engine becomes even hotter causing more hot spots and more steam.

Evans waterless coolants will not boil around these engine hotspots maintaining efficient cooling performance even when the engine is put under extreme conditions. When water turns to steam it pressurises the cooling system putting strain on hoses and other components. The significantly higher boiling point of Evans coolants means 75% less pressure than water resulting in a less stressed cooling system.

Water contains oxygen which causes corrosion and also allows electrolytic activity which further damages engine metals. Evans waterless coolants eliminate corrosion and electrolytic activity significantly increasing the life of the engine.
