So can someone tell me if stock OEM Mercedes coolant is compatible with regular antifreeze coolant?


What will make me know if its the Mercedes stuff in there?


Might I just add some distilled water? ( I know I risk changing the freezing point of my coolant)

Thanks for the link but it is still unclear.


Is the Mercedes stuff the same as zerex? I don't want to drain and refill just add. Can I use zerex in place of the Mercedes stuff to top off?

How low is it and where do you live? If all you have to do is add a little, then I might just go with distilled water as you mentioned. If you live in FL and raise the freezing point from -40 to -30 who cares?

So my LAPS just sold me peak European blue which they say is compatible.


Anyone confirm or deny this?

Zerex G05 is the right stuff. I bought it at Advance Auto Parts.

The Peak coolant appears to be correct. Mercedes used to use G05, the yellow stuff, but in a service bulletin switched to G48. The blue G48 was used in older VWs and Saabs in the '90s and BMWs too, I think.

Here's the link to Mercedes 325.0 spec and you will see G48 at the bottom. To add further confusion, VW called this stuff G11 because that was a piece of the part number they used for it.

Alrighty then. Newer information is better! Thanks.
