Is the fan cutting in? Bubbles in the water pump circuit are often the cause of overheating, it can be a real pain to eliminate them all. Running the heater on full and tapping the coolant pipes will help move them bubbles around so you can vent them.

If the fan is not cutting in, it could be the clutch, wiring or a blown fuse?
