62’ heater core repair question

[Bonello711]

Possibly a stupid question... Aside from replacing a heater core with a small hole, is there any way to repair it without removing. Like “stop leak” or something?

Thanks for all the replies (or lack thereof). I figured it out myself and fixed the issue.

All i can say if you have a Radiator shop Near by best off to take your copper and brass radiator and heater core down and have them both done at the same time they will rodd them out and Pressure test your tanks then clean them and Sauder the takes back on. If possible have them Put in a top reducer so you don't have to run the funny top tank hose have a look
