C-Class estate S205 220d antifreeze coolant specifications and capacity?

[WordSmith]

Hello, I possess a 2018 C-Class estate S205 220d. I am seeking to get my automobile serviced at an independent facility while providing my own parts.


Could you please specify the required specifications for MB coolant and the necessary capacity in litres?
I am seeking to dispense the red/pink coolant. One is designated at MB 325.6 - Is this accurate?

What other third-party coolant is recommended as OEM? Thank you in advance.

Yes, it is the pink variant; I believe it requires approximately 8.5 to slightly over 10 litres to completely fill the system.

The Factory fill has a lifespan of 15 years.

I would purchase any pink coolant provided it bears the manufacturer's reference. MB325.6 is correct.
The capacity of my 2012 S204 C220 is 6.5 litres (blue variant). I would consult the manual or search for it online.
I find it somewhat peculiar that the S205 has a capacity of 8.5 to 10 litres.

I purchase a concentrated solution and dilute it with 40% to 60% water, as advised, using a ratio of 2 to 3 parts water. That is satisfactory for weather conditions in the UK.
