MOTUL AUTO COOL OPTIMAL ULTRA is a concentrated long life antifreeze that should be mixed with soft water for immediate use as a cooling liquid, based on monoethyleneglycol, using an Organic Acid Technology (OAT) additivation named Organic Tech. Strongly recommended for all cooling systems: passenger cars, heavy duty, construction and agriculture vehicles gardening, ships, stationary engines.
Optimal protection of cooling systems against freezing and metallic parts against corrosion OAT technology provides an excellent thermal exchange and therefore improves engine cooling efficiency and prevents from boiling. This organic technology provides anti-corrosion properties that remain at high temperature and aging.
Important: coolant specifications are not interchangeable. Mixing incompatible types can cause the inhibitor package to drop out and block the cooling system. Flush the system if you are changing type.
Vehicle compatibility: suitable for cooling systems specifying this coolant technology. Specifications are not interchangeable — check what your vehicle requires and flush the system if you are changing type.
