Red Long Life Concentrated Coolant

Red Long Life Concentrated Coolant

Nulon Red Long Life Coolant Concentrate provides the ultimate anti-boil, anti-freeze and corrosion protection for all 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 5 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 6 years or 350,000 km, (whichever comes first).

Nulon Red Long Life Coolant 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 33% to 50% by volume in soft or demineralised water. Nulon RLL provides maximum protection against cavitation erosion of wet cylinder liners in diesel engines. Nulon Red Long Life Coolant 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 Long Life Coolant , always thoroughly flush the system first as cross contamination will reduce the life of Red Long Life Coolant .

Benefits

  • 6 years or 350,000 km service life (whichever comes first) when used as directed
  • Guaranteed to suit every vehicle where red/orange OAT based coolant has been specified
  • Provides optimum, long term protection against corrosion of all cooling system metals
  • Compatible with hoses and rubber fittings
  • Expands operating temperature range of cooling systems (see details below)
  • Eliminates the need for supplemental coolant additives (SCA) in diesel engines
  • Reduces the incidence of nucleate or hot spot boiling
  • Not aggressive to water pump seals as is often the case with silicate based coolants
  • Performance of OAT inhibitors does not diminish with time
  • Particularly effective in controlling cavitation erosion of wet cylinder liners in diesel engines

Nulon RLL is recommended for use in all vehicles that use a red or orange coloured coolant. Nulon Red Long Life Coolant is principally designed for use where OAT coolant is required. It is particularly suited for use 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.

Recommended step-by-step guide for changing all concentrated coolants

  1. Before proceeding, read your owner's manual as some vehicles may have special requirements.
  2. Check that all hose connections are tight. Also check the condition of all hoses, fittings and belts.
  3. Use Nulon Radiator Flush and Clean (R40) to ensure that the radiator and engine are as clean as possible. This ensures maximum coolant life.
  4. R40 should be added to the old coolant. With the heater on, run the engine, or drive for 20 minutes minimum or 1 hour maximum.
  5. Stop the engine and allow it to cool. Remove the bottom radiator hose or drain plug to drain out all the old coolant. It is important to rinse out all traces of old coolant from the engine block and heater circuit. To best achieve this, refill the system with clean water, then run the engine up to operating temperature and when it is cool drain and flush it again. This will ensure a clean environment for the new coolant.
  6. Check the cooling system capacity of the vehicle and add the required dose of Nulon Concentrated Coolant (do not pre-mix) then fill with soft, clean or demineralised water. Any leftover product can be pre-diluted and used as a top-up.
  7. Some vehicles may require "air bleeding" to remove trapped air from the heater circuit and cylinder head. An air bleeding screw is located on the engine of some vehicles for this purpose. If you are unsure about this procedure please seek further advice before proceeding. Removing the return heater hose from the water pump to establish water flow, whilst topping up, will assist in reducing "air locks". Note: air locks can cause severe engine damage.
  8. Start the engine and monitor coolant level and temperature until the thermostat opens and the vehicle reaches operating temperature.
  9. When the vehicle cools down re-check the coolant level.

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.

The coolant I purchased has changed colour in the bottle. Has it gone off ?

10 months ago

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.

What is meant by Type A and Type B coolant?

10 months ago

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.

What is ethylene glycol?

10 months ago

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.

Related Questions

Is rain water suitable to add with Nulon coolants?

1 year ago

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.

Can I mix different colour coolants?

1 year ago

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.

Why do I need antifreeze coolant when I don’t live in a cold climate?

10 months ago

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.

Is tap water suitable to add with Nulon coolants?

1 year ago

Tap water quality can vary widley depending on your location. It is best to use deminalised or deionised water, as tap water contains chemicals and minerals which can effect the performance of the coolant.

Where can I dispose of old coolant?

1 year ago

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.

Why does my car need coolant?

10 months ago

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.
