Maybe check the radiator real good for flow. Possibly flush it for good measure?
What about belt routing, I've seen serpentine belts that could route differently than intended. Could the belt be driving the water pump in the wrong direction?
It would be a last resort since it would be pretty involved but maybe pull the water pump and compare it with another to verify the pump impeller is correct / reverse rotation?
