Fix leaky coolant reservior
There have been a lot of references to having a mysterious coolant leak by the passenger tire. I went through the same thing 18 months ago and finally got around to posting a video on how to replace the leaky O-ring underneath. I haven't had a leak since. Hope it helps someone.

I love all of the connections and fasteners on the C7, it is so much fun trying to figure out how they all work. Good job.

Is this the cause of the mysterious coolant smell that I've read some thread topics about?

I have it in the description, but it's the dorman set f4gary mentioned. On my set, there isn't anything labeled as a #6, but there are two 6mm. They both have 6mm inner diameters, but different ODs. I don't remember which one I used, but I took my time comparing them to the original and chose the best

I don't know about smell, but most of the posts talk about a puddle behind the front passenger wheel

No, the #6 I mentioned was from a different video on utube. The largest o-ring in the Dorman pack was something like 19mm i.d. and 21mm o.d.. I had seen that in yet another utube video.
