The fan pulley is one that all I can do for now is run it until it goes bad. That screwdriver slot on the plug is all buggered up on mine to the point that a screwdriver won't start to grab hold. I thought about drilling it out and retapping it but figure that the resulting metal chips would finish that bearing off.
I would recommend NOT letting that happen. I have read more than once on here that when the fan bearing fails, it usually takes the radiator out with it.
Careful use of left hand drill bit will probably snag the screw and pull it out before penetrating to the interior. Then just replace the screw.
If you do get metal filings inside, then you will have to take apart and clean out the fan assembly. I haven’t done this myself, but my impression from what I’ve read on here is that it’s not too bad a task.
