Some months ago I had my radiator out to have a pro shop fix a leak, they were unable to seal the leak in the normal way so they used epoxy. It didn't hold and now the leak is back. The problem as I understand it is that the leak is up at the top of the core at the bottom of the tank. This may be a bit drastic but I'm wondering if it would be possible to cut the tank at the bottom weld and remove all or a piece of it to get access to the top of the core. Is the core for these soldered or welded? I have access to a metal band saw and a friend who can weld aluminum. I would add that a stop leak for aluminum only worked through the summer. So, is this the way to go? It's cheaper than a new replacement.
