Your best bet is to take it to a reputable radiator shop for repairs. I have never had any luck with the 'over the counter' stop leaks. They have caused way more problems than they cured. From stopping up the heater core to water pump failures. If the leak is in the fins or core itself, they can usually be repaired. However, these repairs are not much cheaper than buying a new radiator. If the leak is around the top or bottom of the tank, a new radiator may be the only fix. Most of the newer radiators use a plastic tank now instead of a metal one. I don't know of any way to repair or patch a plastic tank. Hope this helps
