TDV6 Coolant

[Ean Austral]

Gday All,


Will be doing some hose changes and other jobs on the car soon and will no doubt need some coolant to top up the system.


I was just wondering what coolant people are using, and if you are able to mix the coolant with after market stuff.


Cheers Ean

Ean,


good question, I'm going to change the water outlet connector on mine before I do the CSR in July so I have been giving this some thought too.


On the TD5 I use Cat Extended life coolant. is anyone using this in their V6?
it would be good to only keep one coolant in the shed.

Great question Ean.
Do these engines run the same OAT coolant as the D2???? If so the premix Longlife CAT OAT is the go,it exceeds Landy specs for the D2.Its the cheapest you will buy,in 20L drums from your local CAT supplier.Would like to know if its D4 suitable too.

[Ean Austral]

That was the main point of my question, I know the coolant on the D2 could be mixed with an aftermarket OAT coolant.


Not getting many replies here so might have to go to the technical sites for some info. I am sure there is a suitable or better coolant out there.


Cheers Ean

I have been told that AC Delco (genuine Holden) red coolant is compatible.

[BMKal]

I use the standard NULON or CAT Red OAT coolant in mine. Usually have a 20 litre container in the shed, as we also use it in SWMBO's Camry and the young bloke's D2.

Factory specs call for an OAT coolant

Havoline Extended Life Coolant (XLC) or any ethylene glycol based anti-
freeze containing no methanol with only Organic Acid Technology (OAT)
corrosion inhibitors

[shanegtr]

Just had a quick look on the caltex website, I would assume that the delo extended life coolant is the same as the LR spec Havoline

After many conversations with L/R mechanics around Perth , they use Tectaloy Orange Extended factory coolant . It comes in a 5ltr concentrate and it costs about $94 from Coventry's / Cov's. Same as the L/R original mix 50/50 . Don't forget to flush first .;)

So the system needs flushing , so its not a compatible coolant to mix.

Hi Ean,
I've only topped up with Caltex red OAT coolant - no issues with compatibility with LR coolant.

Hi Ean ,
All depending on how much crud comes out of the radiator when you drain it . If its the original orange colour your draining out and you are changing to a different brand [eg green ] , i would flush the radiator out so you don't mix the two. I have also Cat extended life coolant but i was advised not to use it . So i replaced the coolant with the original Tectaloy V- Plus Orange coolant .

Old post but i need to get some coolant and my searches for Caltex/Havoline doesnt bring up any suppliers ?
Searched on Repco, Autobarn and supercrap but got nothing.

[101RRS]

There is nothing special about the coolant - just good quality orange OAT long life coolant.

Need a small top up and was going to use the OEM stuff.

[LRJim]

Need a small top up and was going to use the OEM stuff.Well if it's that brand and you wanna pay the cash go to a caltex servo. Their not that bad I used to get a 1l bottle of oil once a week for the falcon I think it was like $13.
They have coolant but I can't remember if it's red green pink blue purple. The bigger the servo the better you will have options.
Like I said it's the only place I've seen it!

[justinc]

Motorcraft orange is what i use.

[loanrangie]

I had yesterday but couldn't see any level markers ?

Ok hoping not to get shot to pieces here and not knowing much about these differing coolants I am trying to determine what coolant to get and what qty is required.

the D3 had a newish territoy 2.7 fitted about 40,000 km ago and had re-cored radiator fitted at same time. MR did the work and no idea what coolant is in it.

Probably due for a coolant change / flush.

So assuming I get the OEM Clatex Havoline OAT which of those do I get? Any what qty goes in??


Havoline Xtended Life Inhibitor – Concentrate (https://caltexlubricants.com.au/products/details/?cx=1602) 1602 7.5% RED


Havoline Xtended Life Anti-Freeze/Coolant – Concentrate (https://caltexlubricants.com.au/products/details/?cx=3355) code 3355 50% ORANGE

Doing a full flush i would use a different easier to find coolant, no point sticking to OEM.
I went to a couple of caltex servos nearby but they only had the green E/G based coolant so i will use nulon or penrite.

[Ean Austral]

When i done the timing belt , because you loose a fair amount of coolant i just emptied as much as i could and filled up with penrite coolant.

Cheers Ean

[PeterOZ]

got a part number for this magic penrite goop?

i will look at the bottle when I get home. Off the shelf at supercheap and red that's about all I remember .

Cheers Ean

[PeterOZ]

ok I will ask simpler questions.

I assume coolant comes as either a premix or it is added as a ratio to and I'm assuming distelled water, not tap water? If tap water is fine then that is great. One less hassle.

So what is the capacity of the cooling system so I know how much of this goop I need to buy?

Can anybody tell me which coolant I need to buy, not just a brand which does not help with my decision making.
thanks

[loanrangie]

A red or orange oat coolant, capacity would be 10-12ltrs approximately at s guestamation.

[Ean Austral]

This is the stuff I used

You must use distilled/demineralised water only.

[rick130]

And FWIW the original LR OAT was/is? Texaco/Chevron/Caltex ELC, which is also GM DEXCOOL, available from any Holden dealer and almost identical to CAT ELC, which is the Chevron ELC stuff with a couple of supplementary additives.

[loanrangie]

The nulon long life oat lists dexcool as an equivalent, saves going to dealer .
