What the heck?? Coolant gunk

I had Covid for the first time last week. That looks like the stuff I been hacking up.....but way less green!

:rofl:
I should tell them that their Kia has Covid!

Side note: they picked it up and I gave them the run down. Told them what I did and what I found, and when I mentioned the low oil level, they immediately started cussing Walmart. They said, "Not again! We had them change our coolant and they left it empty!"
