Wait for engine to cool.
Remove the radiator cap and check the coolant level. If level is low, top up. If you did not loosens the bleeder nut at the upper hose joint, or is it the thermostat housing, do so and wait for coolant to flow through before tightening the bleeder again. Top up and start engine, if level drops top up till it stabilises and close radiator cap.
If after bleeding and problem persists, you most probably has a blown head gasket.
