Correct engine coolant?

[Justintyme]

Same G48 coolant and warning here .

Good price ?

I bought my Comma Xtream G 48 5 litre concentrate for £21.99 from Ebay Auto Sabre Spares, back in July, so not sure how its priced now.

 

[Justintyme]

Sorry but to meet MB325.6 it has to be
Comma Xstream G40 Antifreeze & Coolant - Concentrated - 1 Litre

They are both oat [ organic additive technology] technology but differ in their pH [ acidity] and life 3years G48 v 5years G40
To be honest I don't know if there is a significant difference or not but I would stick with what's in there already?

Question is are they compatible with each other, that is mixable together as they are both OAT based?

 

[Justintyme]

Isn't the original MB coolant good for 15 years?

If so why are the supposedly MB-approved products only good for 3 years or 5 years?

Yes, that is what is claimed anyway 15 years... but how can you be sure that it's the very same fluid that was used by the manufacturers, 3, 5, 7 or more years later? Is there anyway of having a sample checked? That was the problem I faced in mine, so I decided to do a drain and flush, an refill with Comma Xstream G48, MB Bevo 325.0. So now I know where I stand with it. But does anyone know if MB A 000 989 08 25 10 ( Bevo 325.0 ) is mixable with the Comma 48?

The service booklet for my W203 (M271) and W204 (M274) says 15 years.

Yes, and assuming that you owned the car from new, and had its full service history, then you could be pretty confident that it was the original 15 year antifreeze that was in it. But, other wise.. I would not take a chance by topping it up with another antifreeze, even if it was a MB approved one. There are a lot of people who still think that all antifreeze's are the same.

 

[Justintyme]

I have a 2011 E200 CDi (W212). When I asked the main dealer which antifreeze I needed, they asked what was the colour of my current coolant. When I told them that my oil cooler went kaput and my coolant is now unrecognisable, they suggested that red was more modern then blue and gave me a 5 litre container of concentrated pink anticorrosion antifreeze The spec is labelled as MB 325.0 and the part number is A0009890825 /11. It costs £25.89+vat. Appeared to be a better bet then ECP.

The adviser reckoned that the coolant capacity was around 7 litres and that I would need around 3.5 litres of the concentrate and that It was cheaper to buy a 5 litre container as the 1.5 litre bottles were £11.21+vat each.

The colour and the quantity appeared to be based on guesstimate. Not seen an authoritative referenceable source on capacity. I have more then enough but good to know how much I need to mix.

The container gives no description regarding guarantee period and also does not mention type, e.g. OAT, etc. It does indicate that a 1:1 ratio would give protection to -37C so it implies that top up's of water in future would be just fine.

Hi Mubasher, Mine is a 2010 Eclass W212, CDi M651.9 engine, and I have just carried out a flush and change using Comma Xstream G48, MB 325.0 . compatible. I bought 5 ltrs of concentrate, which made 10 ltrs of fluid, and it took 7.5 ltrs to fill it up.

Total bag of worms.
Should be the most simple of things and MB should make it so. This is not rocket science, its the availability of information about your cars anti freeze.
As for the 15 yrs life of the fitted anti freeze, I think that's great if your able to test it. My simple tester gives me an idea as to its strength but I do wonder if the Techs at your MB service do anything more then top -up. I would be a little concerned if I had a 10 yr old MB with the original anti freeze. As I live in Surrey the winters are mild when compared to "Up North "

All very silly , cars could be made to use one coolant and one 30 grade oil.

That would be in car ( and owner) heaven Gazwould…..I can understand the continuous evolution and research and development of metals etc used in engine / transmission metals, and therefore similar evolution in the fluids used in them too. But its the sheer quantity of all the different grades and compositions, and identifying which one suits your car that annoys me. Mercedes Bevo Nr.s gives the MB-Approved list, and several manufacturers will qualify for this list BUT no clue if the different manufactor's liquids are interchangeable with each other, and that's the problem.
I use the following:-
ATF = FEBI 30018,
Anti-freeze= Comma Xstream G48,
Engine oil = TOTAL QUARTZ INEO MC3 5w-30 LL Synthetic MB 229.52.,
Brake Fluid = Ferodo DOT4.
For now, at any rate, the above list is what I will use, and that will remove the uncertainty ( until they change things again !!! ) LOL

As proof of the colour, I have attached a pic. The Comma G48 I bought, is in concentrate form, but I wonder if the mixed version has a different colour? Just a thought, as there seems to be a bit of conflict about the colour of the Comma Anti Freeze. I also posted a pic of the drained and flushed Anti Freeze. I have no way of knowing if it is the original Mercedes 15 year antifreeze or not. Maybe some one more knowledgeable than me can throw some light on it, based on its colour? Not that it really matters now as I refilled with Comma Xstream G48, so for future reference I know what to top it up with.

 

[14emerc]

Well my from new 2014 has blue anti freeze when I took a sample.
Here is the info from MB for anti freeze sheet. Note: The latest update Date as being 31/10/18
It shows Comma G48 as one of the suitable types.

As for engine oil, mine needs Low saps c3 as its a Diesel engine .

Going by the age of your car 2011 and the Orange colour of the coolant ---referring to the chart your previous coolant would have been the HOAT -G05 based type -----

Thanks for the info Graeme, yes, I'm sure that you are right, it most likely is the original antifreeze, from when the car was new. And any work carried out by the MB dealership earlier on ( timing chain and sprockets replacement ) they would have used the same antifreeze at that time. My problem was that due to a small ( very small) coolant loss, I was topping it up with ordinary water, so the mix was becoming diluted....and I did not want to add antifreeze, and risk adding the wrong kind, then having a bigger problem. I went to my local MB dealership, and they recommended MB A 000 989 08 25 10, but they could not tell me if it was mixable with the existing antifreeze....so I flushed the system out completely, and refilled with the G48. So now my only question is if the MB A 000 989 08 25 10 I purchased is compatible with the G48 I have put in the car? Your advice / comment's are welcome, Graeme.

Yes, and that chart show's exactly the point I was trying to make... they all meet MB BEVO 235.0 for antifreeze for my w212. BUT, are they compatible with each other, if they were mixed? Its a bit like 2 cars having the same destination, but with several different routes to choose from. So if you just want to top up the level, with a small amount....you cannot be sure if it is compatible, or will have a bad reaction. The Total Oil I am using ( as in the pics ) is a low SAPS oil, as mine is a diesel engine too.

 

[Gazwould]

I can't see anything wrong with mixing any of the OAT , HOAT or SIOAT and G48 Glysatin ( is it OAT ? ) , but then again I'm probably wrong , lol ?

FROM BEVO the answer is yes as both are listed as approval 325.0 and would appear to be GLYSANTIN G48
MB 325.0 - Anticorrosion/antifreeze agents (Specification 325.0) - Mercedes-Benz Specifications for Operating Fluids

Gazwould, I don't know either...…...That's why I was asking so many questions here on the Forum...because, I assure you, had I mixed them together in my car, with my luck.....there would be loud rumblings in the engine department !!!!! But it's all cleared up now, Thank's to Graeme,

 

[Gazwould]

Lol , its so fascinating but frustrating , definitive answers are hens teeth .

 

[14emerc]

The reason I hunted down the correct anti freeze is because I found to my cost£££ , adding the incorrect type resulted in engine damage. This was 10yr back now but lesson learned..the hard way!

 

[Justintyme]

Yes Graeme, I saw that as well, the listed ones are all meeting Specification MB 325. As I understand it, individually, they are all suitable for my Merc., But technically, all I could find about the composition of the Mercedes Anti Freeze, was that it was "NITRITEFREI", and for the G48, was that it was " GLYSANTIN", but nothing about OAT, HOAT, SIOAT. And as I am not a chemist, I did not know if they were compatible with each other...And it's entirely possible that the same end result ( antifreeze to -35 etc) could be produced, which would be chemically different, but achieve the same result but still not be compatible with each other...And the MB dealership, were not able to tell me either. You would think that the information sheet that comes with them indicate if they were OAT, HOAT etc. Would avoid a lot of the confusion. Thanks again Graeme for your help, much appreciated.
