Repco's Red Long Life Coolant is safe for vehicles requiring a premium Organic (OAT) Type A Red coolant including Audi, BMW, Ford, Holden, Hyundai, Jeep, Kia, Mazda, Mercedes Benz, Mitsubishi, Porsche, Subaru, Toyota, Volvo, VW and more. The Organic Acid Technology (OAT) specially formulated inhibitor package is more stable and stays in solution longer than traditional coolants. This provides an extended life. It will not form solids inside cooling systems, or become abrasive to water pump seals. Suitable for vehicles already using Red or Orange coolant. It should not be mixed with conventional non-OAT technology Coolants. Eliminates the need for Supplemental Coolant Additives (SCA) in diesel engines. Reduces the incidence of localise or hot spot boiling. Particularly effective in controlling cavitation and erosion around wet cylinder liners in diesel engines. Meets or exceeds the performance requirements of the following coolant system specifications: OEM Specification for OAT coolants ASTM D-3306 / D-4985 / D-6210 AS 2108-2004 for Type A Coolants JIS 2234 SAE J1034 GM 6277M Ford WSS-M97B44-D Consult vehicle owners manual for cooling system capacity and filling procedures.
