EVANS WATERLESS COOLANT - CLASSIC COOL 180
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.
The Science behind Evans
Traditional water based coolants regularly cross the thermal boundary that separates Efficient Nucleate Boiling (A) from Inefficient Critical Heat Flux. CHF leads to localised film boiling (B) and steam bubbles circulating throughout the cooling system, which often results in overheating and combustion issues. Evans Waterless Coolants boil above 180º C ensuring effective cooling and efficient fuel burn is maintained for all engine loads and ambient air temperatures.
When water-based coolants vapourise adjacent to the combustion zone, hot-spots are formed. These hot-spots have been proven to cause pre-ignition in petrol engines and detonation issues in diesel engines. Evans Waterless Coolants eliminates hot-spots and subsequently improve combustion efficiency and increase power delivery.
Water is the root cause of corrosion in all cooling systems, via oxidation (rusting) and galvanic (electrolytic) action. Evans coolants do not contain dissolved oxygen and have a much lower conductivity (increased resistivity) compared with water-based coolants. Subsequently replacing water with Evans non-aqueous solution eliminates corrosion and the need to periodically refresh or replenish the coolant.
Water requires additional (cap) pressure to prevent it boiling within the engine. This additional pressure can vary between 7psi and 29psi (0.5 Bar to 2 Bar) which places significant stress on cooling system components, including hoses, gaskets and radiators. Evans Waterless Coolants generate much lower pressures, in the region of 4psi, and therefore reduces strain on all components.
No Liner Pitting
Liner pitting is primarily caused by the rapid formation and collapse of small steam bubbles on the metal surface. Over several years this process can lead to severe surface erosion and deep liner pitting. Evans Waterless Coolants are not prone to forming vapour bubbles and proven, by SAE trials, to virtually eliminate surface erosion and pitting.
Evans Classic Cool 180° is formulated for engines that have nodular cast iron or aluminium blocks and fewer copper components. Trusted and recommended by top restoration experts.
