A ready-to-use coolant, really top-of-the-range, high-performance, versatile, and fully compatible with all coolants and antifreezes on the market. Enables initial and long-lasting treatment of the cooling circuit (if used as a spare) against corrosion and other surface attacks. Protects the cylinder head and cylinder block from overheating, which destroys surfaces by corrosion, erosion and cavitation perforation. Combats foaming causing leaks via the radiator or tank cap pressure valves. Miscible with all coolants on the market, including type D fluids.
