Hi,

I bought a 2015 Nissan Note E12 last year and the coolant is holding up ok but I'd like to buy a bottle to have around. When I tested it the colour was blue. I did a search but I keep finding conflicting info. Does anyone have a particular one to recommend?

Blue coolant is often just a two year concoction..(but not always).
The E12 should have Nissan L248 GREEN longlife. For peace of mind I'd change all of it, unless you have a service record showing you exactly what's in there. To make things complicated Nissan now currently DO put BLUE longlife in their cars, so you may have that newer stuff but only the records or garage that looked after it can tell you

That's very useful to know. I called my garage (the car was previously maintained by the Nissan dealership) and they told me that their records show that they just topped it up but he told me it's THE PINK one! So.. I'm a little worried cause I just checked it again and it's definitely the BLUE! Perhaps they switched it and it was pink before. In any case, they told me that they can check it for me free of charge whenever I need it cause they can test the strength so I don't need to worry about it. He also said that this time of year I would only need to top up with water. So far it's still near max - from the little that I can see cause with this tank is difficult to tell so I think I'll leave it to the experts! Hehe!

Pink... I reckon he was just being sarcastic. However if they topped it up I'd guess it was at least proper Nissan coolant so no need to worry. I'd never top up with plain water personally because over time it will dilute the mixture.

Official lubricant info from Nissan: https://www-europe.nissan-cdn.net/content/dam/Nissan/gb/Ownership/Maintenance repair/NISSAN LUBE CHART 2017.pdf


For passenger cars, Nissan has only two OEM coolants:
L248: Green (The first interval is 60k miles/60 months on Note E12 pre-2015)
1342


L255N: Blue, Longer life than L248 but I don't know exactly the interval. Started to replace L248 on newer Note since 2015.
They are mutual compatible.

As I know, colors are freely decided by each manufacturer. Antifreeze itself is colorless just like water.
But it would be dangerous for the engine if an incompatible type is mixed in.
Therefore, I would go with Genuine one instead of aftermarket.

I have not changed coolant on my Note 2014 since bought used 2 years ago. I am not even sure if previous owners have ever changed the coolant, so I decide to test it following this video:

The freeze temp is near the bottom, which means the anti-freeze is almost in perfect shape:
1361


His voltage test between the radiator fluid and ground is quite creative, and costs nothing since I already had a voltmeter.
But it keeps dropped in my test, maybe the current through liquid is too high.
I found that touching the radiator cap is much more stable. It is 106 mV, well below the 300 mV threshold as said in the video. So it is all good.
1360


The final test is using pH test strip for fish tank which I stole from my wife.
(Actually I did this test before watching the video, since I heard that it would be bad if it goes acidic)
The pH result is at least 8.5, again as good as new.

So my conclusion is that the Manual's recommendation is just an approximation. I won't change it at specified interval if it is still at great shape.
On the other hand, if it goes bad before the interval, I would definitely change it.

The same happens with transmission fluid. If I own a CVT Nissan, I would change it at least every 30k miles and install a secondary oil cooler for CVT, even if they say it is sealed for life.
