It was interesting because when I had the bleed screw open, the level shot way down and emptied the ET, then returned when I would tighten the bleed screw. So basically I just waited, added coolant, pumped some out until the level was at the correct amount while the screw was closed. I'm assuming an air bubble or something passed by the sensor that I didn't get 100% out? I'm feeling good about the coolant level though because I do have heat, and usually thats the first thing to go, no?

Edit: When I put the cap on and took it for a drive, it was after about 10 minutes had gone by where the level in the ET had no bubbles emerging.
