Thanks Scott. Yes it might be able to be repaired. I would have to make that call once I get it out. The question would come down to if it is worth repairing a 13 year old radiator. I’ve had the unit out twice in it’s lifetime. While it is not too difficult it is still a pain with a bad back and neck. From what I can see it looks like it is leaking where the core connects to the top tank. On the good side, it will give me the opportunity to replace the belt, thermostat, temp sensor etc again while it’s out. Thanks again
