Hello;
Could someone tell me the correct coolant (and mybe a source for the product) to use in my cooling system on a 2007, MB C280 3.0L V6.
Thanks!

as far as i know the green prestone antifreeze is compatible with everything. or so it says on the bottle.


i dunno if that helps or not.

I was told prestone and other like it are not to be used under any circumstances....

Buy genuine MB coolant from your local MB dealer. You need a coolant that has a ph of 7 that won't erode/corrode engine internals and cause plastic cooling system components to become brittle. Zerex also makes a coolant that is acceptable for use in engines with aluminum alloy internal parts.

Use the MB coolant or Zerex G05 only. It's not just the pH that limits the corrosion. Never put green stuff in an MB.

Thank you. Would you happen to ave a MB part number?

The number is not in line with usual MB part numbers, but it is Q 1 03 0002.
