If you have the lower chamber filled to its correct level, and the upper is full, maybe air bubbles in the system? Only reason I can see if you're not losing coolant externally or internally. Didn't you just have the engine looked over? Think I saw that, and if so maybe their's some air still in there. Just my guess
