If you accidentally drill through, you can thread it clear through. Coat a short stub from a bolt with permatex(or whatever sealer). Screw it in from the inside leaving an original depth hole.

With everybody's help and suggestions I drilled the hole with a left handed 1/8" bit and a lot of the left-in-the-hole screw crunched up as the drill bit broke through the back of it. I couldn't get the tapered tap to enter the hole and clean out the rest of it, so I reamed the hole with a #26 bit, the correct size for tapping the hole. Then I could get the tapered tap started, and then cleaned out the rest of the hole with a bottoming tap. And the screw fit the hole good and it appears the threads are the cleaned out original ones. So all is good now. And I would like to thank everyone for their help with this project. Now I need to finish cleaning up the remainder of the fan and all the associated attachments and get this new radiator back in and go mow some grass.
