Take off the radiator cap and run the engine for 10-15 mins until hot. You should be able to look down into the radiator and see the water moving if the thermostat is open. Never heard of a bleeder screw as it is a recirculating system.
Could be too much hard deposit build up in the radiator or too many fins bent over blocking air flow. Have you checked the fan and fan clutch?
