Sounds to me as if it is a cap for the hole in which an old style temp gauge
sensor fits into. On my BN6 my temp gauge sensor fits into a whole as you
describe. This ws change in later models.

I have a 1966 BJ8 Mark 3....my question is on the top tank of the radiator -
underneath it ..there is a threaded cap. Does anybody know what this is
used for? I am getting ready to have the radiator cleaned and need to know
if it can be removed.
Thank You..any and all information would be greatly appreciated
