Don’t use rainwater! Full of minerals, salts and solids.

Demineralised water only.

I guess the only advantage is you could use this across multiple cars and coolant types.

NOT THIS ONE.. unless you are prepared to do a complete flush of the entire cooling system.

Nylon Red...

This one is perfect for a little top up..


You can switch to “One” but need a full and complete flush of the system.

I’ve had a look at the manual and it specifies Castrol SF antifreeze which is silicate free and not compatible with anything that contains silicates.

Cant find anyone that sells Castrol doing a google search around Sydney so I think my safest option is to go back to Land Rover service and get bent over and have them do a top up. They don’t seem to want to tell me what they are using so I’m kind of screwed as I dont want to mix fluids etc.

What a PITA for a simple thing.

Cheers everyone for chiming in.

I’m sorry but I believe you are wrong on this statement. This product is designed for this purpose, to safely mix with any existing product. As I stated though, when you know you need red, why you would use this over red I don’t know, apart from as I mentioned, reuse across different vehicles.

Because on their Datalink where you select the vehicle engine etc it states “see note 834”

Note 834 states “complete flush required”

Land Rover Genuine coolant:

STC50529 1 litre bottle
8510373 20 litre

there is also a 5 litre however I don’t have the part number handy.

Definitely only use the land Rover coolant anything else is asking for trouble
Wyatt's definitely know what they are talking about
Perhaps the best LR people around
