Tiny Pinhole leak in left radiator

I have a tiny pinhole leak in the left radiator about 3/4 of the way up it. I am wondering what kind of product I can use to patch the leak or if it can be done at all on the left one. I really would like to avoid replacing the radiator because the leak is so small.

Noticed a little coolant dripping from the left side engine cover and after some inspection discovered a tiny little stream of coolant being sprayed on the the frame and rolling down getting every thing dirty.

Any ideas fellas?


Thank You,
Rudy

I would try some JB weld after a good solid cleaning and sanding.

Also do a coolant flush and replace with good fresh coolant.

If you can't get to it easily, take the radiator to a radiator repair shop and get a quote..

Don't pay too much as a replacement is only $50 + $13 shipping on ebay

If you try to JB weld it you can pinch off the flue where the leak is. Pinch it off on each side by the header so that flue no longer carries coolant.That will help reduce the pressure on the weld. You should check the cooling system for any stray electrical current. Electrolysis is the likely cause for your problem. I would not advise using any additave like barsleak...it constricts flow...kind of like slime in a tire. You dont want that in your engine/cooling system/carb heater circuits.
