John Woods Motorcare Ltd are happy to announce that we are now Evans Waterless Engine Coolant Stockists.
Waterless Coolant for Classic Cars
Classic Cool 180° is the coolant of choice for many restoration and classic car specialists. For manufacturers such as Eagle, no other coolant offers the complete protection of Evans waterless coolants.
Power Cool 180° is the coolant of choice for many professional racing teams and performance car specialists. For manufacturers such as Noble, no other coolant offers the performance of Evans waterless coolants.
Evans Prep Fluid is formulated to hygroscopically absorb water whilst flushing loose dirt and scale from the cooling system prior to filling with Evans Waterless Coolant.
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. 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 (see physical limitations of water). 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 (see chemical limitations of water). Evans waterless coolants eliminate corrosion and electrolytic activity significantly increasing the life of the engine.
