Evans Powersports R Cool 180° is formulated for road bike enginesconstructed from aluminium, steel and copper components. Designed for bikesthat tend to suffer with overheating problems. Water-based coolant often boils,it is due to them spending most of their time with the throttle fully open.With Power Cool 180°C installed, riders are able to stay on the gas and this isthe reason why most factory teams use Evans.The engine will operate at lower pressure, putting less stress on hoses,radiators, pump seals etc. Evans Waterless Coolant - Why is it a major step forward For nearly 100 years we have been adding water and ethylene glycol(antifreeze) and corrosion inhibitors into our cooling systems. Water basedmixtures are not the ideal solution due to the limitations that exist withintheir chemical and physical make up. These limitations affect engineperformance and can lead to engine failure.60% of engine failures can be attributed to cooling system failures thisconfirms the inherent flaws
