So I've had "Baxter" for a year now (that's its name), and I've always had some kind of moisture on my trunk lid when I checked the oil.. Ive always just wiped it off and ignored it until today. I went into a restaurant for 10 minutes and when I came out, there was a huge green puddle under my car.. It had puked out its coolant!
After I filled it back with water, I looked underneath to see where it was coming from.. Right wheel, sounded like an overflow issue.. The water I added didnt come out so I carried on. So when I got back to the office, I googled the hell out of it and ran across some things about the coolant cap.. I checked mine and I have the *00 numbered one (ordering a replacement tomorrow), but I also found some info on bleeding. So I removed the cover to pop open the bleed/vent valve and found this..
Is this something I should be concerned about?
