Yup,
All of these suggestions are about pressurized systems which is not what Jerry has.
Jerry,, How many holes have you found?
Got a solder gun or an LP torch and a roll of solder?

Jerry:

I've used Barrs Leaks several times with good results.  On a couple of cars, I had heater core leaks and one application of Barrs stopped the leaks permanently (several years and no recurrances).

On my American LaFrance racer, I had the radiator cleaned at a radiator shop.  BIG mistake!  They hot tanked it and it leaked so badly, they wouldn't fix it.  The bottom tank had most of the leaks but the "honeycomb" core also had some.

The shop sent me home with the leaky radiator and a jar of what they called "boiler sealer".  The stuff looked like metal powder and was probably composed of a mixture of bismuth and other low melting point metals.  Their instructions were to put the radiator back on and cover the radiator so the engine would heat-up.  Use a wash tub to collect the leakage so it can be poured back in.

Start the engine and add water until the radiator was full.  After some heat was built-up and after dumping back the leaked water, add the entire contents of the jar (about a liter, I think I remember).

For a while, nothing happened except that the water leaking out of the radiator was real pretty with the silvery metal in it.  It took a few refillings (using a tin can from the wash tub) but, after a while, as the engine got to the boiling point, the leaking slowed and finally stopped.

They said to just leave the stuff in the radiator and I did.  No more leaks - ever.

A few years later, I did drain the radiator and the water was clear.  I dunno where the sealer went but I'm glad it worked.

Take care - Elden
