Thread: Which Anti-Freeze in Td5 Defender

Important Info

Use only ethylene glycol based anti-freeze (containing no methanol) with only Organic
Acid Technology (OAT) corrosion inhibitors to protect the cooling system.
IMPORTANT: No other anti-freeze should be used with anti-freeze containing OAT corrosion inhibitors. Coolant solution must not fall below 50% anti-freeze otherwise damage to engine is liable to occur. Maximum concentration is 60%.

PERCENTAGE CONCENTRATION - 50% PROTECTION - LOWER TEMPERATURE LIMIT
Complete protection
Vehicle may be driven away immediately from cold, -33C).
Safe limit protection
Coolant in semi-frozen state. Engine may be started and driven away after warm-up period, -41C).
Lower protection
Prevents frost damage to cylinder head, block and radiator. Thaw out before starting engine, -47C).
CAUTION: Anti-freeze content must never be allowed to fall below 50% otherwise damage to the engine is liable to occur. Also, anti-freeze content should not exceed 60% as this will greatly reduce the cooling effect of the coolant.

Check your service manual.
In my Discovery Td5 it states that you MUST use the OAT coolant. This is the red coolant that is sometimes hard to find..not everyone stocks it. I use the Nulon Long life but still change the fluid at half the recommended by LR.

I think thats what the RAVE disc is saying?

Cooling system - Td5 13.00 litres of coolant is required.

Thank you for the speedly replies, I knew that they cut corners on the service, my fluid is definitely NOT green or red/pink for that matter.....
Ever since Stewart Webster(Frankston) changed owners many people that Used to service their vehicles there have not gone back.......Bastards, and it was so close and convenient too..........

Thanks for the tip, so it's flush and refill.........

the factory fill is Texaco(Caltex) Extended Life OAT coolant. It's a fluro orange in it's concentrate form. Available from a Land Rover dealer or a Caltex servo.
If you get it from Caltex, make sure the bottle says 'Extended Life Coolant' and 'lasts 5 years'. It will also have something about 'Carboxylate Protection' on the container. This refers to the carboxylate organic acid used as the inhibitor.

I use it in my Tdi and SWMBO's Patrol.

cheers all, all info taken aboard, shopping on Thursday....

Hi guys. I recently had a new radiator fitted and was advised by my mechanic (an LR specialist in Frankston) to use Valvoline GO5 concentrate (green in colour). Mine had the pink coolant before but in his experience it can become quite corrosive and also prone to developing a positive charge. Upon checking the coolant before the radiator replacement it was indeed found to have a charge 3X higher than the recommended level.

Never had my cap off..

Does this red stuff have the slimey feel that the green stuff does?
