Check the hoses and around the clamps to see if it is possibly leaking from there. Radiator sealer works fine on small leaks.If all else looks good you are on the way to have your rad repaired.(also check around the water pump,when they go they leak bad!!) if the sealant doesn't work and you can see where the leak is coming from, then remove the radiator, if necessary, drain it. you then need to clean the area where the leak is with a wire brush and alcohol. then get a small plumbers torch and some resin core solder and seal the leak. if that doesn't work you may have to have it recored or buy another one.
