Thread: Replacing Coolant

Description of Nulon Red (OAT)
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 Acid 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 5 years or 250,000 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 .

Description of Nulon Green
Nulon Long Life Concentrated Coolant offers long-term cooling system protection for all motor vehicles. Nulon Long Life Coolant is based on Hybrid Additive Technology (HAT), which is a blend of organic and inorganic additives. The advantage of this product over conventional ethylene glycol type coolants is that the corrosion-inhibiting package has minimal depletion over an extended period of time. This means that maximum corrosion and anti-freeze/anti-boil protection are maintained until the fluid is replaced at the recommended 250,000 kilometres or four years (whichever comes first).
Nulon LL Concentrated Coolant is to be used at 33% to 50% by volume in soft or demineralised water. Nulon Long Life Coolant protects for four years or 250,000km and is safe to use in all Commodores and Ford Falcons (including all V series Commodores and AU to BF Falcons).
Nulon Long Life Coolant is a low silicate formulation containing no nitrite, phosphate or amine. These chemicals are often used in conventional coolants and have limitations in performance, protection afforded, and vehicles to which they are suited. Nulon Long Life Coolant is guaranteed suitable for use in all vehicles where the manufacturer specifies anti-boil/anti-freeze coolant.
Nulon Long Life Coolant meets the specified requirement (HN2217) of General Motors Holden for use in all Australian manufactured four-cylinder vehicles. HN2217 is the specification recommended by GMH for all warranty servicing of Australian built and imported (Opel) four cylinder vehicles.
Nulon Long Life Coolant's formulation is approved by Ford Australia (ESE-M97B44-A specification) for initial fill in all Australian manufactured 6 and 8 cylinder vehicles. This specification is recommended by Ford for all in-warranty and post-warranty servicing of Ford vehicles where a glycol based coolant is required.
Benefits:

• <LI class=maintext>4 years or 250,000 km service life (whichever comes first) <LI class=maintext>Guaranteed to suit every vehicle <LI class=maintext>Provides optimum protection against corrosion of all metals in vehicle cooling systems <LI class=maintext>Compatible with hoses and rubber fittings <LI class=maintext>Expands operating temperature range of cooling systems (see details below) <LI class=maintext>Eliminates the need for supplemental coolant additives (SCA) in diesel engines <LI class=maintext>Reduces the incidence of nucleate or hot spot boiling <LI class=maintext>Not aggressive to water pump seals as is often the case with silicate based coolants <LI class=maintext>Performance of organic acid based inhibitors does not diminish with time
• Reduces inventory for fleet operators

Sorry to break into a TD5 discussion.... But the same would go for the TDi alloy head engine?

OAT or Nulon type coolants would be OK for this engine? Although there was some mention of OAT coolants creating issues with capitation corrosion on engines with water pumps not designed for the stuff?

While I know this is about the TD5 related probs, i bought a bottle (4 ltre) of the Nulon long life concentrated, mono ethylene glycol, the other day,
on the side of the bottle the aplication sheet says 'Landrover' all models'
4years/ 250,000 plus a heap of data on complying with international standards and manufacturers requirements.
doesn't say anything about oat. But the specs are gobblydee gook to me.

I think its what I put in a couple of years ago,

I have recently changed my coolant. When purchasing (Repco), with reference to JohnE, I saw this same bottle of Nulon (Green) coolant, it did state 'All LandRover Models', I was searching the specs and could' nt find what I was looking for. I called the technical line within the store. No anwser was given for the 'All LandRover Models' printed but it was suggested that the red OAT coolant was the correct product.

Thanks for that all my questions on this issue have been answered. I will endeavour to thack down some oat coolant.

up2nogood you did notice this didn't you...

Nulon Red Long Life Coolant is not recommended for use in cooling systems that have a copper/brass radiator

Didn't know the TD5 had a plastic one.....

Plastic tanks, aluminium alloy core.
