Coolant brand experiences / brand recommendations

After having some coolant leaks over the past few weeks and the upcoming summer months, I’ve decided it would be a good time to replace the coolant in the patrol.

Now besides not mixing coolants, I don’t know much about them.


Nissan quoted me $65 for 5L of genuine.

Supercheap have nylon green ($40) and also a heavy duty red one specific for diesels ($60)

The I found another nylon green one at Costco for $16!!

Now the Costco one is a premix, so I’ll need to buy 2 bottles todo the same job.

Anyone used the nulon (or any other brands) over the genuine Nissan and had good experience?

That first Nulon mate I've used on all my 4x4s. 2 Patrols and a navara and it appears it does the job just fine.

Brunswick Diesels puts genuine nissan coolant in all their conversions, reckons it covers all the bases for they chev conversion.

I put the first Nulon in the Hyundai Excel.
Read the fine print, 18 litres at 33%, 12 litres at the recommended 50%.
Concentrate is better than pre-mix because there is always some water left when you finish flushing.

I use the first Green Nulon. I wonder what the actual difference is, apart from colour, and labeling, between the two Nulon variants.

Was wondering the same thing. The second one says Diesel and 1,200,000 Km?!!
I'm assuming the "diesel" bit is maybe for the trucks since they do a ton of km's? I dont know. As above, Ive been using the first one for years . No dramas.

Min and max operating temps by the look of it - its on the label!!!!

Thanks for all the feedback guys, here’s the back labels of the two nulon ones from supercheap if it helps

Yeah I'm just a skeptic though. I've been in this trade for over 20 years now and seen a few tricks to generate sales in my time. So I tend to question the validity of some things.

we use the first one to,john deere tractors,change cooland as per manual,every so many hrs or years..they prob do 1.2milkm...but i bet they change the coolant more often than that lasted the whole time..

only ever used the green stuff, whether it was the premix or concentrate

what colour did it come out with. red is supposedly better for the plastic components, how true this is is anyone's guess. if they came out with green i'd stick with the green.

I use the same as Clunk , sometimes premix sometimes concentrate always the not red stuff .

Doesn’t it say anywhere on the bottle what the percentage of glycol is? 100% ‘concentrate’ on it’s own is pretty meaningless.

The 5 litre bottle of Nulon (green) I have at home is stuff I bought around 18 months to 2 years ago. It was priced at $38.80. It’s label says ‘Long Life Concentrated Coolant 100% concentrate 1060gm glycol per litre’

The label says suitable for 4 years/250,000kms. for all petrol, diesel & LPG engines.

At a 33% (5 litres make up 15 litres) mix ratio it raises boiling point to 127 deg.C & lowers freezing point to -18 deg.C
At a 50% (5 litres makes up 10 litres) mx ratio it raises boiling point to 132 deg. C & lowers freezing point to -37 deg.C

50% is recommended for heavy duty diesels.

From that info I would suggest that the likely difference between those pictured above is the amount of glycol per litre.

I’ve got a 50% mix in mine. If I had realised the boiling point was 132 deg.C I would have been less concerned when my temp gauge was showing 100 deg.C when pulling the Tvan up to the Barrington Tops!

As for the 4, 5, 6, 7, or 8 years ....... I reckon that’s just marketing nonsense. How many folk would leave their coolant unchanged for 8 years?

If the label didn’t tell me the amount of glycol per litre I’d buy a different brand that did.

Just saw this in 4wd action. http://www.nissanpatrol.com.au/forum...2017/11/91.jpg

Good find!

I have always used repco concentrate and then Coles bottles of demineralised water X 3. Get it mixed to 40 per cent and run for 50000km and dump. Never had an issue with the coolant causing problems and nil crud in the cooling system...20 bucks cheaper than the nulon stuff too.

Just to throw another variable in, my Patrol came with BLUE coolant.
