Engines run cooler up to 15°C (30°F). Improves thermal exchange and engine cooling system efficiency. PERFORMANCE Improves thermal exchange and engine cooling system efficiency. Cooling system optimal protection against corrosion Recommended for magnesium, aluminum alloys cases, cast iron, copper, brass and bronze systems. Water pump protection, avoid cavitation Anti-corrosion properties that remain while high temperature and ageing. Low corrosion inhibitors consumption. Seals, rubber pipes, and plastics parts friendly. RECOMMENDATIONS MOTUL MoCool is a concentrated cooling fluid that may be mixed with distillate water for immediate use as a coolant. To be mixed with water at 5% (20:1). Do not use pure product. Can be mixed with most coolants monoethyleneglycol based.
