A little warning: Adding stop leak products can clog small passageways in your cooling system.
Bars leak has a good reputation for doing a good job. However..being the radiator..it is probably a plastic endcap and as the operating temp is reached it expands and contracts the plastic....it'* doubtful stop leak will work well for this type of leak.
