  • I use a cut bicycle tube attached to the inlet and outlet to enable a quick check on my solder patch. Add a pound or two of air and spray the repair with soapy water. Bubbles show the patch isn't finished.
    Cartridge cases are another cheap source of small bits of brass sheet to patch with.

  • Re: radiator leak
  • If it is a hole poked in from the front and easily accessed it is simple to solder up providing fins and tubes are sound. If the radiator is corroded and flaking it may not be worth it. I clear away damaged fins, crimp off the damaged tube/tubes and after draining the radiator then clean them well. Sometimes brake cleaner can be sprayed on to pre clean. When parts are clean solder with the same flux and solder you would use on copper piping. Parts are small and delicate so a big flame is not needed, I use a pencil torch from Harbor Freight, costs a few bucks, it uses lighter fuel gas that some drug stores and smoke shops carry. Heat tube and solder wire almost at the same time, as soon as solder starts melting make sure it takes to the damage. Let cool and test fill. Once while I poked a stick through my 2N radiator, Had to get the job done and the whole repair process took a little over an hour, that was about 15 years ago and it is still holding up.

  • Re: radiator leak
  • I like your thinking GP.
    Ain't No kind of patch as good as the real thing - solder.
    Repairs on gas tanks, fuel lines, radiators all last better when you solder them.
    But I fear soldering is becoming a lost skill. Guys would rather use some kind of glue or pucky than even TRY their hand at soldering.
    I have a partial gallon of muriatic acid here that I use for cleaning the metal before soldering. It does wonders. But it at Home Depot or Menards. They use it for cleaning brick. Works wonders for cleaning calcium out of toilet bowls too.

  • Re: radiator leak
  • A straw is a pretty good size hole for a radiator. I'd advise you to take it to a trusty, local radiator shop, and those are getting harder to find. Some options are BAR-Z-ALL and old timers use to use oatmeal to seal small holes.

  • Re: radiator leak
  • If the hole is too large, insert a cut off brass screw and solder that in. Works great.
