Green and Yellow Coolant - Mixing?
After replacing my thermostat in my 2011 E350, I needed to add back in some coolant. The original coolant is green, and I only had some yellow Zerex G-05, which is also for Mercedes.
Now, I just read that mixing green and orange coolant will cause it to gel and mess up your engine. I'm not sure if the yellow coolant will do the same.
Did I do a big goof?

Aside from the question whether or not to mix different coolants (no opinion here), once mixed, the result will be a different color, neither green or yellow. Not bad if you can remember which coolants they were... I assume quite bad if you can't.
