Thread: Green V Red coolant......... which one?

Go red coolant this has oats which is what land rover recommend your coolant leaks could be a result of the wrong coolant in the first place. Will it leak when you refill the cooling system probably.

You don't really know what that that green coolant is, HOAT which is organic OAT is also green. Your right worrying about putting OAT in now as it probably will find all the weak spots.

Why is it that it that OAT does that? - i mean find all the weak spots and is that a bad thing? All the major Euro car makers recommend it - even Holden.... so it can't be bad (ie destructive), can it?

OAT= organic ACID Technology, may be its the Acid??? maybre it eats scale, probably why when Oat is added to a system that has had other stuff in it it eats the crud away which was probably sealing the system??????

the old school green coolant is "thicker" than the red stuff. The red stuff has a lower surface tension and is also more compatible with dis similar metals so your high nobility cast iron block will not sacrafice your lower nobility aluminum radiator or your oil cooler via the coolant as readily.

Thats the exceptionally simple version there are other differences .

Heres the kicker back in the day it was simple you had green coolant and you had red coolant now you have every bloody colour under the sun picking coolant by colour is like going into bunnings to the paint colour chart and asking for "blue" umpty million shades later and youve come home with the wrong one.

While I advocate only running OAT (and I personally recommend Nulons stuff) If you have a potentially compromised cooling system (if youve run green coolant to ease up leaks its compromised) then get HOAT coolant.

In a pinch run anything you can find to keep it full if you have to get it hime.


DONT pick your coolant by colour, you have to read the label to make sure you get the one you want.

The cheapest and best OAT is the CAT extended life coolant.
Around $100 for 20lt premix.
It exceeds Land Rover specs.
Get a price from Westrac,and try GP1200(Jack) he is a Truck part parts manager in WA.He will be able to get you 20lt drums of synthetic oil for a TD5 cheaper than anywhere.
When I was running 2 TD5's Andy at Diesel Motors Trucks was the go for CAT OAT and Synthetic oil.

My opinion only.
I run the red because that's what mine had in it
DO NOT mix them. If you want to go to red, make sure the system is totally free of the green first with thorough flushing.
JC on here is a big fan of the green and he knows what he's on about, myself I'm of the keep what you've got school.
One benefit of the red is it's impossible to miss leaks they show up like the stuff is fluorescent

Colour means nothing. Get the LR specification.
