True silver solder has a high melting point and it's possible that
a small propane torch may not generate enough heat on the
radiator to properly melt and bond.  Get a "silver bearing" solder,
which is basically ordinary solder with 2%-4% silver content.
The melting point is about 100degF higher - like about 430 to
470 deg depending upon exact alloy.  I think Sears has a
reasonable selection, if I remember correctly.

Use an acid based flux on anything non-electrical.  However,
be sure to wash the area thoroughly afterward, as the acid
flux can be the gift that keeps on giving, if you get my drift.

If all you can find is rosin core solder, that's OK.  Just brush
on some acid flux and go for it.

BTW, I'm assuming this is not aluminum?  Different set of
problems.........
