2003 G270, Coolant Spec
Hi,
For my 2003 G270 Diesel I don't have access to Mercedes coolant. Does anyone know the spec for what coolant to use? I looked in my manual, my DVD parts program and googled for a while and don't see the spec anywhere.
Thanks,
Steve
That's very easy. It's the same coolant as used by any other Mercedes. Today, this is a G05 (Mercedes spec) coolant, but previously it was G48, which is marginally better - at least with cast-iron blocks.
if you want to know more, look here, half way down:

in the USA, you might find this:

or just buy the normal (blue) stuff (G05) from your local MB dealer.
Some is sold ready diluted and ready to use. Others come as concentrate and require diluting 50:50 with water or distilled water, is your local water is 'hard'.
