Mercedes OEM Coolant
 

I have recently read that the MB coolant you buy from the dealer is premixed 50-50 with water.

Is this true?

I just paid $31 for a gallon, and if its 50-50, I am gonna be unhappy for $31 / half gal coolant. Thats $62 / gallon!

Bought some Zerex G05 to make me feel better.

Do I have to redo my recent coolant change (as I added 50-50 distilled water to the MB product).

Anyone know if the OEM coolant is 50/50 or pure coolant?

Someone must know.

It should say on the label. if not call the dealer you bought it from.

It's not.

It is not premixed. The gallon bottle should have part# q 103 0002. At $31 I think you paid way too much.

Honda offer pre-mixed A/F but not MB.

Thanks for your insights.

I wholeheartedly agree that $31/gal for OE coolant is r@pe. But its the dealer.

That's why I picked up some Zerex G05 for the future @ $15/gal.

I avoid my local dealer for everything I can. The left rear door actuator I bought online @ $195 was $245 + tax at dealer. I chuckled and told him I would find one elsewhere.

Just bought some MB coolant from the dealership for $15. Not premixed. I could not find the correct zerex in my area.
