Just to show it did all happen today:
Just an FYI: When I pulled the plastic cover off underneath on my FG2, it turns out there's 2 small "trap-doors" on both sides of it. One said AC and the other says Coolant. Apparently you don't need to take it off, you just open the trap-door and access the tap control.
I think I'm good with the new coolant now, I wanted the car level so I could get as much out as possible, but the overflow bottle didn't really clean up as well as I wanted (I should just buy a new one now). While it was all up though, I wanted to do some other things, that's where it all went bad. But that's not for this thread... I'll create a new one...
