What Coolant is Cool?

[VSStatus]

Hi guys,
well the old VS Caprice and HJ ute (would love to have been able to keep them:boohoohave been replaced by a VZ SS Crewman Thunder.
Gotta say pretty happy with it.
I am wanting to top up the coolant but am unsure as to what to put in?
I have used genuine holden coolant before in the VS but it was a bit of a drag having to go to metro and then also mix it with demin.Call me lazy.
I changed to Tectalloy 90 plus in there with no issues i could tell.
Now i have heard that an engine will instantly disintergrate and the world will start to spin backwards if different coolants are mixed together.
What are your thoughts on this?
What coolant do you use?
Kind regards and many thanks in advance,
Shane.

I stick to the genuine Holden stuff. Your car will run the red type GM coolant, can't remember the part number.
BTW you should not mix dissimilar coolants.

Thanks for that mate.
Hehe.I havent even taken the cap off to check colour but even though a bit of a hassle will
stick with the genuine stuff I guess.
Is it a mix yourself thing?
Cheers.

You need the red coolant.

Proper flush is always recommended

Green coolant is for iron blocks (V6) an red is for alloy blocks (V8)
Apparently the green corodes the alloy

I just read up and its what is recommended, and so why install something that isnt.

Quote form Nulon
Red Long Life Concentrated Coolant- Nulon Australia

Applications:
Nulon RLLTU is recommended for use in all vehicles that use a red or orange coloured coolant. Nulon RLLTU is principally designed for use where OAT coolant is required. Use RLLTU where AS/NZS 2108.1:2004 Type A, GM6277M or Toyota TSK2601G specifications are cited. Use in all cooling systems as a replacement for any red/orange coloured coolant. Among specific makes of vehicles that use red/orange coolant are Ford Falcon EA - EF, Holden Gen 3 & Gen 4 V8's and Alloytech V6, all Toyota models, Audi (some models), VW (some models), Jeep (most models), Chrysler (most new imports have red), Isuzu trucks, Daihatsu cars and trucks and Caterpillar

oh not this dusscusion again as long as you flush everything it dosent matter what ####in colour,,, ITS type A for commodores not type B

Red is generally for alloy and green for cast... But I would use genuine because the new bt50 and ranger use a red coolant and they have a cast block. So use genuine.

Lol not the colour myth again. It's the ingredients. Stick to propylene glycol. If you're unsure, flush and top up with the one brand.

Cheers guys.
yep coolant is red in there.Will get some Holden concentrate and mix up a batch with demin.
Cant go wrong then I guess
Thanks.

Also from what I have read it is best to do a complete flush and fill with one brand?
Just topping up with either nulon red or Holden genuine may be an issue if i dont know what is in there?
Cheers.

Mine had Genuine Holden red coolant in it, then I had to change my radiator -filled it up the remainder with the Nulon Red Long Life. Just make sure the red Nulon you get has the GM6277M compatible listed on the back as that's what works in a Holden. If you put a lot of coolant bleed the system too.
