If it is a hole poked in from the front and easily accessed it is simple to solder up providing fins and tubes are sound. If the radiator is corroded and flaking it may not be worth it. I clear away damaged fins, crimp off the damaged tube/tubes and after draining the radiator then clean them well. Sometimes brake cleaner can be sprayed on to pre clean. When parts are clean solder with the same flux and solder you would use on copper piping. Parts are small and delicate so a big flame is not needed, I use a pencil torch from Harbor Freight, costs a few bucks, it uses lighter fuel gas that some drug stores and smoke shops carry. Heat tube and solder wire almost at the same time, as soon as solder starts melting make sure it takes to the damage. Let cool and test fill. Once while I poked a stick through my 2N radiator, Had to get the job done and the whole repair process took a little over an hour, that was about 15 years ago and it is still holding up.
