Thank you....

This looks like the diagram on the decal near my radiator. My complaint was that following some of the tubing from a source on the wheel well, it transitioned to a color different from what the diagram was telling me (on the other side of the check valve nipple).

I also didn't want to try rearranging tubing to get colors to match up. I would never get it back to the original state if I started doing that.

Was that diagram out of the Mercedes manual if so what was the title of the manual?
Thanks again.
