e39 radiator drain plug/hose leaking

e39 540i experts: Need your help.
I drained the coolant from the engine block (2 bolts) and the radiator last night, but I have the type of radiator that doesn't have a drain plug but a small plastic angle connector attached to a rubber hose. You twist it 1/4 turn and pull out the connector to drain.
With the connector back in, there is residual coolant leaking at the connection point
Did an o-ring fall out, or is there a part option to seal this up properly? I can't refill the radiator until I fix this....

Any specifics, please advise (e.g. part #'s), nothing on realoem helped me.
