update....
I took the fill plug off, and let it drain until it just dripped (after searching this topic).
BUT.... As i was taking the the drain plug off, i noticed that it was under pressure.. Yes i drove the care prior, like a 30-minutes ago, but how could there still be pressure? It hissed as i unscrewed it, as the pressure released. I hope i don't have a clogged vent?
