My 2000 chevy silverado 5.3L overheats. The water in the top hose boils and the lower hose is cold.

I tried bleeding trapped air by removing the cap and running at high idle/ The lower hose doesn't collapse. The heater works and there is no noticeable coolant loss. The radiator fan works. No white smoke in exhaust. Thanks for any ideas.
