Thanks for the input. It is an original style radiator and temp is perfect... never any problems there. I do not have an overflow hose attached, nor an overflow container, but I actually bought one a little while ago that I have not yet installed. It has never overflowed through the open “nozzle” either. The leak is on the other side and drips off the bottom right by the drain plug. I’ll look closer to find the exact spot. Over last winter I had the engine pulled to fix an oil pan and rear main leak, plus replace the motor mounts (and repaint it while it was out). I suspect those guys damaged the radiator during the process. The leak is so minor that I was looking for the least work possible to fix it! :-)
