Nulon Red Top-Up Long Life Coolant (RLLTU) is a pre-diluted, read- to-use 50/50 mix of Nulon Red Concentrated Long Life Coolant (RLL) and demineralised water. RLLTU is formulated to be used in either of two ways:

1. Add as a top-up to any cooling system that contains Nulon Red Concentrated Long Life Coolant. Or, use to top-up any cooling system known to contain the following products :

• Holden Extended Life Anti-Freeze Coolant
• Ford Long Life Anti-Freeze Anti-Boil Concentrate
• Dex-Cool®
• PrixMax MEG95

2. Use as a complete fill product. This is particularly advantageous in areas where water is of poor quality, or is very hard, such as Perth and Adelaide.

All performance characteristics of Nulon Red Top-Up Long Life Coolant (RLLTU) are exactly the same as for Nulon Red Concentrated Coolant (RLL) when RLL is mixed 50/50 with water.

RLLTU provides the ultimate anti-boil, anti-freeze and corrosion protection for all late model vehicles, including petrol, diesel and heavy duty diesel applications. RLLTU incorporates the most up to date Organic Additive Technology (OAT) carboxylate corrosion inhibitors. RLLTU is nitrite and amine free to meet US requirements, phosphate free to meet European requirements and silicate free to meet Japanese requirements. Nulon RLLTU's carboxylate inhibitor package is more stable and stays in solution better than traditional coolants. This provides an extended shelf life of 5 years. Nulon RLLTU will not form solids inside cooling systems, or become abrasive to water pump seals. All of this means that RLLTU provides maximum corrosion and anti-freeze, anti-boil protection for up to 6 years or 350,000 km, (whichever comes first).

Nulon RLLTU is the preferred coolant to use in systems fitted with aluminium radiators. It is a genuine 100% OAT based, long life coolant. RLLTU 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.

Nulon RLLTU provides maximum protection against cavitation erosion of wet cylinder liners in diesel engines. Nulon RLLTU 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 RLLTU, always thoroughly flush the system first, as cross contamination will reduce the life of RLLTU.
