Coolant colour

[CJPNAV]

Hi all,
I have recently purchased a 2012 D40 140kw Navara and I am changing all fluids. What colour coolant do they take ? Some say blue, others say red or green ?
Thanks for your assistance.

Mine's green.

The coolant, that is.

My 2011 D40 and my friends 2012 D40 both use the blue stuff. We've recently changed our coolant and used this diluted 50/50 with demineralised water:

Coolant colour is just a dye. You just need the right spec, colour is unimportant.

I've just changed mine on the weekend and the search at 2 places said blue for a 2011 d22 str 2.5lt

Colour is usually indicative of spec.

I'm not sure I like the idea of colours indicating the specifications (I don't doubt it, I'm saying I don't like it). Years ago, you'd have fluoro green coolant because it was a different colour to every other fluid in the car (sump, diff, fuel, gearbox, power steer, hydraulic) so when it landed on the ground, you could tell what it was.

Seeing as you aren't supposed to mix the different specs, it makes it easy for us dumb owners; comes with blue ... top up with blue, comes with red ... top up with red, etc.

True for a single brand, they will have a variety of colours indicating the specification of the coolant.
If you select a different brand the colours will not necessarily be the same.

In reality, mixing antifreeze, while not recommended, isn't a problem ( excluding dexcool which is whole different problem,)

Not necessarily, I agree, but more likely than not.

As a rule most manufacturers follow these colour schemes. So almost impossible to determine which coolant is in the system by its colour.

IAT blue or green.

HOAT orange, pink, turquoise blue or yellow

OAT orange, red, yellow, purple, blue, pink, dark green

Nissan blue is OAT by the way.

The most important thing is never to use HOAT or OAT in a roughly pre 1990 vehicle with brass and solder as part of the system.
