Nulon Red Long Life Coolant Concentrate 5L - RLL5
Nulon Red Premium Long Life Coolant 100% Concentrate (RLL) provides the ultimate anti-freeze/anti-boil and corrosion protection for most late model vehicles, including petrol, diesel and heavy duty diesel applications. Red Long Life Coolant incorporates the most up to date Organic Additive Technology (OAT) carboxylate corrosion inhibitors. Red Long Life Coolant is nitrite and amine free to meet US requirements, phosphate free to meet European requirements and silicate free to meet Japanese requirements. Nulon RLL's carboxylate inhibitor package is more stable and stays in solution better than traditional coolants. This provides an extended shelf life of 8 years. Nulon RLL will not form solids inside cooling systems, or become abrasive to water pump seals. All of this means that RLL provides maximum corrosion and anti-freeze/anti-boil protection for up to 8 years or 500,000 km, (whichever comes first). Nulon Red Premium Long Life Coolant 100% Concentrate is the preferred coolant to use in cooling systems that are fitted with aluminium radiators. It is a genuine 100% OAT based, long life coolant. RLL is dyed its distinct red/orange colour to instantly distinguish its unique chemistry from traditional green coolants. It should not be mixed with other coolants. As it is a concentrated coolant, it is to be used at 50% by volume in soft or demineralised water. Nulon RLL provides maximum protection against cavitation erosion of wet cylinder liners in diesel engines. Red Premium Long Life Coolant 100% Concentrate is not recommended for use in cooling systems that have a copper/brass radiator (in such vehicles, use Nulon LL, which is green). If changing from any other coolant to Red Premium Long Life Coolant 100% Concentrate, always thoroughly flush the system first as cross contamination will reduce the life of Red Premium Long Life Coolant 100% Concentrate.
