My guess would be a common pipe thread but I've never had anything that new.

12 MM IS CLOSE - DOESN'T GO IN EASILY BUT THAT MAY BE FROM CORROSION ON THE INSIDE. I GOT THREAD PIECES COME OUT ON THE BOLT WHEN I SCREWED IT OUT.

These engine coolant plugs were plastic from the factory. Be careful what you put in there! AC 5020 and the 5030 were the same plugs.
