Is it magnetic? If it can be determined that it is an NPT product maybe just changing the material used and an appropriate sealer is a more desired repair. Is it maybe NPS? Is it maybe an ISO 7-1 pipe? Is it maybe Metric? It's a "once and done" thing. Identifying the removed plug I'd think critical - no guessing - use thread pitch gage and appropriate measuring devices.

On second thought......I completely concur with
WVZR-1.....he is DAMAN. I am not sure if there is enough material or thickness to start drilling/threading for one thing never having even removed said plug. And concur on the removal of the Oil Cooler also. It is pretty easy to try all sorts of sealers for sure depending on the situation.
But if you DO remove the radiator....time to inspect and clean the trash from both the radiator and Oil Cooler...AND....AC Condenser.
