Looks like I lost a little bit of coolant, but nothing alarming.
Out of curiosity: is it possible that there was too much coolant in the system, and the excessive ambient temperatures in this heat wave plus lots of stop and go with the a/c on caused the coolant to expand so much that it bubbled out of the bleed screw?
I just thought of that a minute ago.

The coolant level was just a smidge above max. Not by much though. Like a half cm on the float - and that could have been because I was looking at the wrong angle. Oil level was fine - if not a little low (I fixed that on the oil change) - but it's still within spec.
HOWEVER, when I switched the bleed screw yesterday, I noticed the old screw did not have an o-ring and there was no o-ring anywhere to be found. I double-checked where the o-ring would sit when making the seal, and it was not there, either. The new screw had an oil ring. I ran the car for about eight minutes with the a/c on and everything and go it up to temperature. I have not noticed any leaks yet.
My guess right now is that either there was too much coolant and it bubbled out, or the lack of an o-ring caused the leak. The old screw did not appear to have any cracks upon a quick inspection. Perhaps the no o-ring situation was the cause.
There is supposed to be an o-ring, correct? Or am I thinking about drain plug?

No there's supposed to be an o-ring. My new one came with an o-ring. Plus it's two plastic pieces trying to seal a fluid in. There's gotta be some rubber in there to help.
OK....that's what I thought. I think you found the smoking gun (no o-ring/blown o-ring)

Same here.
Thanks for your insight!
