ANTIFREEZE-COOLANT SI-OAT 50% is a new-generation antifreeze-coolant with hybrid technology, developed through the combination of organic acids and silicates. This technology combines the advantages of the previous technologies: selective action and longevity of organics, and the immediate response of inorganics (silicates). Specifically designed for vehicles requiring MAN 324 Type Si-OAT refrigerant. Approved for use in Euro VI engine trucks.
