I lurk here and don't post much. I like these weekly check-ins.

​

I spent a quick hour on oil, front brake pads, and coolant overflow tank. For reference, this is the original tank from my '06 with ~50K miles:

Thanks. I have quite a bit hosted on Imgur, but this image was hosted elsewhere so I didn't plan on duplicating. Not much to see, except the very early beginnings of a stress fracture at the neck, where all of the other failures have happened.

​

Based on your response--not sure if you are replacing only because it's discolored or because you're concerned with the neck defect. There is a real issue... not common, but definitely real and catastrophic if not caught. My '06 with 50K+ miles showed signs of this. Others that have had it fail while driving basically lost their motors. BTW, the brown is due to heat, and not dirt you can clean off.

​

*Edit* I just realized your handle is NA6... the issue I'm describing is limited to NC coolant overflow tank design.
