Nulon Premium Long Life Pre-Mix Coolant – Red (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 Red Premium Long Life Coolant 100% Concentrate (RLL). Or, use to top-up any cooling system known to contain the following products:
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 Premium Long Life Pre-Mix Coolant – Red (RLLTU) are exactly the same as for Nulon Red Concentrated Coolant (RLL) when RLL is mixed 50/50 with demineralised water.
RLLTU provides the ultimate anti-freeze/anti-boil 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 8 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 8 years or 500,000 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.
Nulon RLLTU is recommended for use in all vehicles that use a red or orange coloured coolant. Nulon RLLTU is principally designed for use where OAT coolant is required. Use RLLTU where AS/NZS 2108.1:2004 Type A, GM6277M or Toyota TSK2601G specifications are cited. Use in all cooling systems as a replacement for any red/orange coloured coolant. Among specific makes of vehicles that use red/orange coolant are Ford Falcon EA - EF, Holden Gen 3 & Gen 4 V8's and Alloytech V6, all Toyota models, Audi (some models), VW (some models), Jeep (most models), Chrysler (most new imports have red), Isuzu trucks, Daihatsu cars and trucks and Caterpillar.
Note: This check sheet should be used as a guide only. Some vehicles may have special requirements that are not noted above. We strongly advise that you read your owner's manual or relevant workshop manual before proceeding with a coolant change.

Nulon coolants do have a shelf life. Nulon Green Premium Long Life Coolant 100% Concentrate and Green Premium Long Life Pre-Mix Coolant have a shelf life of three years. Red Premium Long Life Coolant 100% Concentrate, Blue Premium Long Life Coolant 100% Concentrate, ONE 100% Concentrate Coolant and Heavy Duty Diesel Coolant 100% Concentrate have a shelf life of five years.
No, it is OK to use. Dye is added to coolant for identification purposes. The dye used to colour the coolant, green, red, etc can be affected by sunlight and age but this does not effect the performance of the coolant.
In 1977 an Australian Standard was created to help regulate the quality and performance of automotive coolants in the Australian passenger car and light commercial market. The current standard is known as AS2108-2004. Type A coolants are antifreeze/antiboil coolants with corrosion inhibitor that comply with the requirements of this standard. Type B coolants are coolants with corrosion inhibitors only that comply with the requirements of this standard.
It is best to use deminalised or deionised water. Uncontaminated rain water is OK but if collected from roofs and gutters it can contain impurites which may affect coolant performance. Metal roofing materials, concrete roof tiles and tanks, dirt and dust, all contaminate rain water. These conatanimants have an adverse effect on your vehicle cooling system.
Yes it is suitable but often more expensive than demineralised or deionised water.
Tap water quality can vary widely depending on your location. It is best to use demineralised or deionised water (Radiator & Cooling System Water), as tap water contains chemicals and minerals which can affect the performance of the coolant.
Most modern cars run their cooling systems at temperatures close to 100 degrees celsius. The bonus of using the antifreeze chemical (glycol) in coolant is that it also raises the boiling point. This gives protection against localised or hot spot boiling which can cause engine damage.
While not essential we recommend using Radiator Flush and Clean to remove insulating built-up sludge and residue before changing coolant in any cooling system.
Yes, coolants that contain ethylene glycol are poisonous. If ingested it affects the central nervous system and can cause death. Nulon adds a bittering agent to its coolants that contain ethylene glycol to prevent accidental ingestion from children or pets.

No, coolant colour alone does not specify the chemical technology of the coolant. It is important to note that when coolants of different technology are mixed the performance is compromised.
Ethylene glycol is a product used in automotive coolants to give the coolant a lower freezing point and higher boiling point. This allows vehicles to operate in sub zero climates and also allows engine coolants to reach higher temperatues before boiling.
We show you how to change your vehicle's coolant in this easy step by step video.
Nulon shows you how to change your vehicle's coolant in an easy step by step process.
All you need to do this is: car jack, jack stands or ramps, screwdriver, socket or spanner, drain plug washer, oil drain pan, some rags, container for the used coolant, Gloves and Nulon Long Life Coolant.
Internal combustion engine generate large amounts of heat. "Coolant" simpy means a liquid that provides temperature-transferring properties. In an automotive cooling system it is required to transfer heat from the engine whilst protecting the engine from corrosion (i.e. rust) and erosion which can be caused by fluid movement. Many automotive coolants also have added chemicals to extend the operating temperature range of the fluid. These are known as antifreeze/antiboil coolants.
Soft water, demineralised and deionised water are terms used to describe water which has low levels of dissolved mineral salts and ions of such metals as calcium, iron, or magnesium.
Using the correct type of coolant is essential. The Nulon Lube Guide can provide a guide to you coolant requirements. If directions of use are followed correctly Nulon coolants will protect the system from corrosion for the recommended life of the coolant.
These abbreviations refer to the technology used in the corrosion protection component of a coolant. IAT is Inorganic Additive Technology (often termed Conventional Technology), OAT is Organic Additive Technology, and HAT is Hybrid Additive Technology. To determine the best technology option and the preferred coolant for your car refer to the Nulon Lube Guide instore or online.
This depends on the type of coolant your car requires and the climate extremes that your vehicle will operate in. Consult the Nulon Lube Guide for the suitable coolant type, consult your vehicle handbook and follow directions of use on label to determine the required ratio.
The best answer to this question can be found in the Nulon Lube Guide, also available in store.
Contact your local waste facilities or environmental protection agency. Used coolants can contain environmentally unfriendly materials that have originated from the engine cooling system and need appropriate disposal. Do not drain used coolant onto the ground or into storm water.
