Radiator Fluids

[Juz]

hey guys wat radiator fluid should I use in my 33. gts

[marvin]

Nulon coolant best thing I ever used + a bottle of wetter watter from redline . . . Best stuff ever

[GT32]

I always use Nulon (or Nulon red in alloy radiators) and a 500ml bottle of Motul Mo'Cool. Temps have never been colder, even on 40+ days!

ive got in a huge arguement with a knowall who knows nothing on another forum regarding coolants, i work in a mechanical repair business specialising in exhausts and radiators, i change coolant every day, use whatver coolant you want, so long as it has anti corrosive properties that dont effect alloy as they pretty much all do anyway so you should be fine. Red or green, it doesnt matter, its just a dye. I cant remember the brand off the top of my head that i use at work but we buy it in big goon sacks in bulk anyway so i doubt it is retailed. We have both red and green and they both contain the same ingrediants, just different dyes. I run this in 2 of my cars and supercheap brand in the other and have never had an issue, neither have any of our customers.

Id use nothing other then genuine coolant + distilled water, 1 part genuine nissan coolant, 2 parts distilled water.

r u joking?

Any 1/2 decent 'green' coolant is fine IMO.

Since I like to get my radiator system checked (& cleaned if needed) every year, I just use the 'standard life' coolants & don't bother with the extra long life stuff (the 5 year stuff).

Nope, i only ever used nissan coolant in my gtr. Pulled the motor down a few months ago and had f**k all corrsion in the coolant ports in the block, which is pretty strange for a motor that old.

Also we have problems with xtrails and d40's overheating at work. Mainly because they've used a non genuine coolant or cheap coolant which has started electrolysis in the aloy parts of the cooling system. Look into the radiator and you will see a fine dust like substance all through the coolant. This infact blocks the radiotars slightly and inturn they over heat. Put your multimeter in the coolant and check for stray current and you will always see a reading well over .3v's in these vehicles. These customers have voided all warrarnty in regards to the cooling system of their car because of this.

Not saying it would be the same in a vehicle with a cast iron block, but just gives you an idea of what can happen. Nissan have also released a tech bulletin to all the technicians about this which gives you an indication of how bad it may be.

I always use battery water ( aka destilled water) + anti-freeze.

Battery water contains no minerals, so that should keep any deposits stemming from minerals (limescale) out of the system.

Also see that the coolant you use is for engines with cast-iron-block and aluminium heads.

Coolants for 100% aluminium engines are of a different consistency.

In general I would say that you have to stick to green or blue/greenish colours.

(Though this might not be a binding rule ...)

Basically there are 2 types of coolant:

Silicate based (green/blue)

Non silicate based (red/purple)

Here's the one I use:
