As a new member I would hopefully be able to help others in the future.

Today I attempted to test loosen the RED CAPPED radiator drain valve petcock.

Snapped off in hand without the internal stem moving at all.

Nothing dripped out YET, but there was a cork like washer.

YT vids show replacing a SIMILAR looking insert of F-150 (7L1Z-8115-a)

No Dorman or Ford parts lists (including dealers) acknowledge Milan Premier having a petcock.

Original owner and radiator never replaced.

COULD drain by lower hose if needed.

Before I Epoxy it over, any help is appreciated.
