Interesting. I use silver solder quite a bit making brass parts for banjo makers. Conventional soft solder melts below 500° Fahrenheit while most silver solders melt above 1000°. I am surprised you didn't melt any of the adjacent soft solder when applying the silver solder.
It seems like it would be quite difficult to repair an area where both types of material were present.

A oxy-acetylene torch or maybe a MAPP gas torch must be used. Silver solder takes a specific flux which must be purchased too...unless you find a flux covered rod.
I guess the part of this thread I am missing is why use silver solder at all. The benefit of the silver solder is its high strength. Most radiator applications do fine with the strength provided by regular soft solder. It's much more about sealing two pieces for a water tight pressure joint than it is about brute strength.

The flux covered rods are usually brass.
