Evans Coolent allows your cooling system to run at a lower pressure reducing the strain on the engine componets.
No water = No Liner Pitting
Evans generates significantly less pitting when compared with all water based coolents
No Water = More BHP
Evans eliminates premature detonation associated with overheating
How it works
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.
Exceeding the limitations of water
Within an engine cooling system the hottest surfaces are those adjacent to the combustion chamber, specifically the cylinder liners & cylinder head. In these hot spots water is likely to vaporise preventing efficient cooling & causing loss of performance & unnecessary engine damage (see physical limitations of water). When the coolent fails in this way the engine becomes even hotter causing more hot spots & more steam.
Evans Waterless Coolents 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 & other components. The significantly higher boiling point of Evans Coolents means 75% less pressure then water resulting in a less stressed cooling system.
The Science of waterless cooling
Since the 1930's engine coolents have been based on a mixture of ethylene glycol, water & corrosion inhibitors. All such mixtures have inherent physical & chemical limitations that restrict engine performance & affect reliability. Evans Waterless Coolents represent a major step forward in engine cooling & engine protection technology.
If you are treating an engine that currently has coolent in it you will also need to purchase the Evans Prep Fluid, also listed in our shop.
Prep Fluid Absorbs Water
Before filling your system with Evans Waterless Coolent it should be as free from water as possible. Evans Prep Fluid hydroscopically absorbs any residual water remaining in the system after draining.
Evans Prep Fluid actively removes the loose dirt & scale from your cooling system which can cause inefficient heat transfer.
