Which Type Of Coolant To Use On Gtr?

[R34 VSPEC]

Hey boyz and girls,

Just wanna get an opinion on types of coolant to use in a GTR. Any particular brands that are good? what ratio mixture should be used?............just want to make sure that coolant types are not detrimental to coolant lines, seals, pumps etc...

Got a mate who recently had coolant changed and was using a 50/50 mixture but car had a syrong coolant smell after the drive................is that normal?

Cheers.

Smell because while ur mate was filling the radiator up he might spill some on the engine?

Anyway, i think the best is to use NISSAN genunie which available from most Nissan dealer.

I agree, the only downside is it's not cheap.

redline coolant with inhibitor (pink in colour) with distilled water. good flush out to get rid of the glycol base from previous coolants + rust dirt general crap etc. the stuff works good with glycol, but better without it. or any good quality 50/50 glycol (the green stuff)

i currently have power steering fluid in my raditaor and it hasnt overheaded! (still not reccomending it!)

Redline Water wetter is not recommended for winter used, only suitable for summer or track use. If you must use RL WW, pls mix at least 15% coolant and the rest distilled water.

Power steering fluid or ATF in radiator is a major no no. The viscosity of the fluid usually 7cSt or more will decrease the heat transfer rate of the medium (fluid) by hell of alot.

General guide

PSF or ATF ~ -50 to -70% decrease heat transfer

50/50 coolant/water ~ normal heat transfer

RL WW/100% water ~ 50% better heat transfer

i used 2L of genuine coolant from nissan to replace all in my GTR block , radiator and hoses. Make sure u use green coolant. and just use the genuine. if ur too cheap to use a $12.50 per Litre bottle of coolant. then ur prob too cheap to own a Skyline. its gonna be an expensive piece of work.

not a good idea to run power steerin fluid in ur coolant true. im not doing it by choice people. NEVER use power steering fluid in ur cooling system

i dont know hows its getting in there but it is. the mechanics trying to figure it out

Thanks for all the feedback guys. Just flushed the system and gone 50\50 Geniune Nissan green stuff and demineralised water..............only the best will do!

Nulon's Green Long Life stuff is actually alright. 5 years protection and just add 33% (of your total capacity) into your coolant system after the flush and then fill with water. Too easy.

I use the pre-mixed Nulon. No worries with mixing proportions, just tip in and go. Temperatures seem absolutely stable (mind you I am in Sydney, not the hotter parts of AU).

[Cubes]

I checked out the Nissan stuff, I was actually suprised how well priced it was. Very similiar to that of good aftermarket gear.

I'm currently running the Nulon green. I did a little research in to what is required in a good coolant and it had good levels of the good stuff.

The nulon green stuff is definitely a good bang for buck coolant.

[Busky2k]

I prefer Nulon's Concentrate because you know you are getting the right ratio going in. Ie 2.5L for a 7L car.

The problem with premixed stuff is that you'd worry about water left in the block which causes dilution. You'd be suprised how much water stays in the block if you dont drain it out.. like a few litres!

I agree, Nulon's Green Concentrate at 20 bux for 2.5L is by far the best bang for your buck. 5 year protection too. Sweet.
