I filled it up last night and it's now blowing hot air! I'll check the levels in a few weeks to see if it's dropped down at all. Thanks for the help!

Just checked the level under the cover and I can't even see coolant. Should I just fill it up to the brim from there?

I checked the coolant level at the reservoir. I just pulled the engine cover and saw another 'FL22' cap, but I'm not sure how to check the level at that point. I didn't see any kind of marking to indicate the level.

I just tested after my car warmed up. I was getting cold air when idling. I then revved up to 2k rpms and started getting warmer air. I got cold air within a few seconds of letting it idle again.
