I know you know where the leak is at. I would go one step further and pressure test it in a tank of water. You plug all the holes and put a fitting in one of them to couple an airline. You don't want to use very high pressure, just enough to fill the rad with air and under water, you will spot the leak. At least this way you can actually pinpoint the problem.
