Did you flush the cooling system? Did you remove all the air from the system? And are you using a 50/50 mix of anti-freeze and distilled water? Just some thoughts I had. I would also make sure the cap and bottle are sealing correctly. And when does it overheat, at idle/in traffic, or at highway speeds, or all of the above? The fan clutch is suspect if it overheats at slow speeds in traffic or at idle, and the electric fan should come on around 215* or so, and anytime the AC/defrost is selected.
