Took a 10 minute drive earlier today, after parking and coming back outside after an hour or so I noticed coolant all over the ground. Did some tests and it looks like the overflow bottle is spewing coolant, all the fluid is coming from the fascia and it's wet all around the bottle. The car got up to the usual temperature when I was driving around (never over 215 or so), but not once did it go any higher. What would cause coolant to spew if it's not getting hot? The temp gauge seems to report correctly (although I have seen it once or twice rise 20-30 degrees then fall 20-30 degrees in a matter of seconds so maybe it's bad even though it's recently been replaced). Almost all coolant is getting spewed out each time, the surge tank ends up running empty, and this sucks... Anyone have any thoughts?
