I too thought it was overheating as the temp gauge very quickly rose to way higher than I'd ever seen it.  I spent hours burping the system with the car on steep ramps in both directions but still the gauge sat just below the 2nd last mark (about 2/3 up the gauge) whereas previously it rarely hit half way except in heavy traffic.
