Shop put in GREEN coolant when I had the M-B orange

[frosty]

Should heads roll? Need to make a stink about it? Is it the end of the world? I'm not mad, but should I? I rememember reading something about GREEN vs ORANGE coolant here before and something about mixing the colors--is this an issue at all? This is a M-B shop that did it, so I guess it's okay? Please advise! Thanks.

Start looking for a different shop.

Judging from the most commonly used look of "orange," the MB coolant is actually closer to yellow.

What perhaps majority calls orange is color of GM-specification Dex-Cool. That's not for Mercedes either.

Well, I fear we will start another coolant thread!! But as I remember, the Mercedes stuff is a clear or slightly "straw" color, not orange or green. And you are supposed to use distilled water!! But I suppose it might depend on the year and model. What car do you have? I assume you are talking about a MB dealer? I assume they should know what they are doing...

First we need make sure that no factory fill long life euro coolant is being sold in the US.
Because when you mix original fill Mercedes blue coolant with traditional Mercedes yellow coolant, and don't drain the block you get a blue green mixture.

Plus what color is the ZEREX coolant that I read is Mercedes compatible?

Indie M-B shop

1990 190E

In for upper/lower radiator hose change

The coolant I put in is from M-B and I guess it's not really orange but more of a pale tp almost clearish orange hue.

My resv. tank looks green now. Looks like a run of the mill GREEN COOLant was added?

Is this BAD? MUST KNOW! Do I need to grind the ax? Thanks.

I have used the Zerex coolant and it is a yellow color like te MB coolant..probably made for MB.
