Hi all,

 

I’m almost out of coolant in my car, I had previously brought Comma Xstream G40  in late 2020 from Halfords as it was stated as compatible via their license plate search. I’ve looked at their website today and it says that my car is not compatible with that coolant.
 

I’m now unsure if they is okay to use. It didn’t seem to cause too many issues when I used it last, but that time I was only topping up a little, whereas this time it would be a quite a bit. The tank in the car says it needs G13, I can’t seem to find out if the comma is G13. Does anyone have any experience with this? I don’t really want to drive the car before it is topped up as I drive on the motorway and the car started to beep and displayed a red light warning to check the coolant.

 

 

Glysantin BASF make the coolant for VW Group,  G65 is to VW spec TL 774 – L which is G12evo

Glysantin BASF make the coolant for VW Group,  GG40 is to VW spec TL 774 – J which is G13

Glysantin BASF make the coolant for VW Group,  G40 is to VW spec TL 774 – G which is G12++

Glysantin BASF make the coolant for VW Group,  G30 is to VW spec TL 774 – D/F which is G12

 

So, for your car I'd think that G40 is the "oldest/earliest" version of Glysantin that is best to use.

 

Currently, as far as I have found, Comma do not provide any later version of coolants for VW Group, but when they do, as before it will have the name of the BASF coolant in it, which will be G65.

 

The better plan will be to find out where the coolant leak is and fix it.

Edited to add GG40 and correct G40

One other question, and maybe a question that I asked first, what is the reg date of your Fabia, as VW Group seem to have a habit of running through their stocks of reservoirs before changing to the next one, so a late car with G13 on its reservoir, could well be an early car with G12evo, the car's documentation will be up to date though.

 

Edit:- always remember that while you should never use an earlier version to add to a later version of coolant, in the range of VW Group, or BASF versions I've listed in my posting above, the worst thing that will happen is you will end up with a slightly "lower" form of overall protection and that will be due to "newest version will always be best" - that in this case of G30, G40, GG40, G65 will not be a disaster like it could be with other mixes.

@LcKirby  Welcome.

 

What engine does your car have & how old and why is the coolant dropping? 

(I know coolant can be lost but is it slowly over a long time with your engine)

 

Is it a 1.4TDI?  

If so see the linked thread at the top of the section.

Neither fully trust any single database or source of information (especially from me) always cross checked .  As has been put Comma Xstream® G40®  is Glysantin® G40® by BASF and listed as VW G12++.

 

Yes the cause of coolant level dropping needs to be confirmed.

 

Coolant specification seems to be another example of VW (VAG) not being as clever as they think they are and changing their minds even as far back as the year 2000.  I really think they need more photos of human body parts to help them know differences.

 

My wife's 2015 Mk3 1.2 TSI petrol has G13 on the tank but I was told it's now G12evo (not to be confused with G12+ or G12++).

 

Coolant is now getting like oils with particular specifications by manufactures like VW, how much of this specification is justified I don't know as I was told by someone that worked for at a VW garage that "G12evo is the latest and greatest and will mix with all previous vw coolants" though I'm not sure if that includes G11.

 

I think we had five different types of coolant without counting the sub divisions of manufactures specifications of those.

 

As well as @rum4mo's BASF's numbering system (which is missing G12+ whatever that is) here 's a chart to add to the general (VW/VAG) coolant confusion.

As BASF are using different colours for their differing "brews" - though maybe the differences are not too obvious, if I was guessing, I'd think that G12+ was also a G40 product.

There's times that I forget that BASF's main division is this kind of stuff and not these...

You are now qualified as a VAG Design Engineer, German engineering excellence. 🤣

Things haven't changed, you don't go German if it's available from the Japanese.
