Just found out today ......................

Post by KennyW »

Hi All,

Tried to order g33 coolant from Citroen today to be told it has been discontinued.

After some research a few months back G30 is very similar to G33 but if I remember correctly they cannot be mixed.

Does anyone know an alternative source for G33 ?

Are you looking to do a top-up, or a complete coolant change ?
IIRC, Comma G30 is a (more or less) straight drop-in replacement, but there are plenty of others that'd do. https://www.commaoil.com/passenger-vehi ... s/view/351
Any of the major fluid manufacturer's such as Total, Mobil, Castrol should provide guidance as to what is suitable in your car on their respective lubricant search / advisor pages such as....

While lots may be suitable, just be careful not to mix types, even by topping up.
If in doubt, drain the whole system thoroughly and replace.

Thanks for the replies,

I'm going to check out Peugeot dealers to see what they have.

Even BASF, the makers of Glysantin, say that G30 is the right antifreeze for Citroens....

Further to the above....
Although BASF say Glysantin products can be mixed, they don't recommend it.

This is an extract from the spec for G33:

Ethylene glycol with corrosion inhibitors

Glysantin ® G33 ® is a coolant based on ethylene glycol,
which must be diluted with water before use.
Glysantin G33 contains a salt-based inhibitor package
organic acids (OAT coolant).
Glysantin G33 is nitrite, amine, phosphate, borate and silicate free.
Properties
Glysantin G33 provides excellent protection against corrosion,
Overheating and frost. It effectively prevents corrosion and
Deposits in the cooling system with its important components such as
Cooling channels in the cylinder head, engine block, radiator, water pump and
Heating heat exchanger.
Glysantin G33 is officially from PSA (Peugeot / Citroën)
approved according to standard PSA B71 5110.
Glysantin G33 also meets the following standards:
AS 2108-2004, ASTM D 3306, ASTM D 4985, SAE J1034, AFNOR
NF R 15-601, ÖNORM V 5123, CUNA NC 956-16, JIS K 2234: 2006,
SANS 1251: 2005, SH 0521-1999 and BS 6580: 2010.
Glysantin G33 is generally available in green.

Sounds suspiciously like the Citroen Antigel I have been using.

The other coolant Citroen recommend / specify is Revkogel 2000.... which appears to be as equally discontinued as the G33 :roll:

Hi all,

The coolant in my Peugeot 3008 (Model 2013) is now between the max and min and will need to top it up to be close to max.

I understand that the current coolant used in the car is G33 (Blue color), but this seems to be discontinued. I see that G30 is also compatible with Peugeot cars and would like to know if it's ok to top up G33 with G30 even though both have different colors (G30 appear to be pink)? Or do you recommend that I drain the current coolant and replace it with G30?

Also in the Peugeot manual , it says that the coolant doesn't need to be changed, only topped up. Is it the same with the G30 or it will need to be regularly drained and changed?

Thanks in advance.

I just found that many Ebay sellers from Germany still sell G33 coolant. Did any of you buy the G33 in ebay? I'm just worried that it might not be genuine.

Hey guys,

Been reading a lot about this and there seems to be a lot of confusion. Replying to the old thread since this is a very high search engine result.
This subject should not be hard but since there isn't really an industry standard spec on colors and type of coolant (VW sort of has), it gets rather confusing. I will update if something changes and this info might have errors.

The TLDR is forget about Glysantin. Search for "PSA B71 5110" and glycol based, as plenty of manufacturers like Motul sell it and is glycol based OAT liquid. This is not really a modern, long life coolant and you should test PH, top up and replace when it goes out of spec (as per oficinal maintenance schedule). Don't add water to premixed coolant![1]

Many manufacturers have B71 5110 products, these are common:
  • Eurol -36 PSC
    Motul Inugel 5110
PH is 7.7 at 50% and 7.6 at 40% dilution, for Freecor DSC. Too much deviation from this and you should replace it.
I would flush and replace if there are deposits visible on the coolant tank, which can and does happen.

Caution:
  • Blue colors are typical of older, incompatible IAT coolant. It is rather nonsense that PSA OAT specs is blue, unlike manufacturers like VW which switched to red/pink.
On many recent cars, Stellantis uses Arteco Freecor DSC, another blue, Silicate, Phosphate and Nitrite free Organic Acid Technology glycol based product. Since this is PSA B71 5110 compliant, in it's datasheet[2] there are PSA coolant specifications which you can use to test and liquid, as mentioned above. They also recommend a "lobrid" coolant as a more modern alternative (see modern Opel/Vaxhuall user manuals), which is hybrid coolant with small amounts of silicates.

Now, a small history lesson. There some main eras in the evolution of engine coolants:
  • IAT coolants used on iron based engines
    OAT coolants for aluminum engines and brass free radiators
    Introduction of modern, environment friendly Glycerol based coolants
    VW goes back to glycol (EG) coolant since 2018 (G12evo/TL 774L)
Inorganic Acid Technology coolants were mostly green but now there are people selling B71 5110 coolant in that color and blue is also a very common VW IAT color. For iron engines, IAT is required.
Organic Acid Technology encompasses also hybrid formulations with lower silicate content but Stellantis seems to prefer coolant that is free of most mineral inhibitors. Strangely enough, VW seems to have gone back to Silicate and Phosphate OAT on the latest G12evo, ditching the Glycerol formulations going forward, after having added Phosphate and Silicates back.

Some manufacturers don't tell you much but will list in package if the coolant is OAT or IAT. Look for PSA Spec listed and otherwise look away.
Other similar spec cooolants, but not PSA approved:
  • Mannol AF13++ ("lobrid" coolant)
    Zerex G30 (purple, similar to Arteco DSC)
    Zerex G48 (blue, w/ nitrites)
Mannol seems stick to Stellantis recommendation for newer cars (NAP free) but you probably want to flush before putting this in. These should offer good protection of chalk deposits, which I have seen on 1.6 BlueHDI with OAT yellow coolant of an unknown brand.
Zerex seems to be "hybrid OAT, low silicate" coolants but Valvoline doesn't provide a datasheet. I wanted to list these as examples of how confusing it can get when comparing with Glysantin product codes. These may be ok but you should use approved ones, as these may pose issues and maintenance schedule will be different.
Nitrites are used in some mixtures to provide extra cavitation protection, or may be required depending on the EG mix. PSA does not use it and the main concern seems to be carcinogen formation when amines are also used in the mix.

[1] The quantity of Etylene Glycol is critical to avoid bubbles on the coolant side of piston walls. Other parts of the coolant formulation will take this into account. Failure to do so will result in local overheating and aluminum cavitation on the piston side side of the engine block. An engine with this kind of damage will require a new block.

Don't rely on colours of coolant whatsoever - they are totally irrelevant and can change from one manufacturer to another.

You must always focus on the specification and content of the actual product and ensure it meets that specified for the vehicle. PSA often change periodically the names for coolants, so if not sure consult the dealer for the specific standard required for your own vehicle.

G30 is only silicate free and from the spec, not B71 5110 compliant. There is coolant that more closely follows specs, or completely, so people should probably go for that.

G30 seems to be sold only in concentrate form, whereas most DIYers should always used premixed to avoid issues.

We only recommend the correct coolant from the manufacturer - not the sales info from other suppliers flogging their own products. This is especially so as coolant type may vary for later engines.
