Found what looks to be the drain plug on the lower left corner of the rad, any ideas how to get it out?
It takes a 1/4" drive but doesn't seem to be threaded, turning it to the loosen just doesn't feel right. Also there is a detent visible in the rad which a pin on the plug drops into.
Of course the Haynes manual doesn't help.
