    If it's a hairline crack NOT on a sharp corner of the casting on a water radiator, try JB Weld (available nearly anywhere).

    Clean very well first with wire brush, sandpaper and a solvent like acetone.

    If it's a steam radiator you should be able to repair a crack anywhere as there is very little pressure.
