W202 C43 AMG Coolant

[DRBC43AMG]

As part of the Winter/Spring maintenance (vehicle is currently in hibernation) I'm going to replace the thermostat on the M113 engine together with a list of other things to do and I was thinking of proceeding with the cooling system flush and replacement.

What coolant should I be using? MB stuff or other type with MB approval? What is the correct fluid code for the MB coolant?

I live in an area with very hard water. Should I fill and mix with distilled or filtered water?

Thanks for any tips.

I use MB coolant but there are lots of good branded coolants. Just stick to the same colour thats in there. Mixing isnt advised.

I didn't know this either, until it was pointed-out to me by a friend who works as consultant for desalination plants.
