Stop Leak Suggestions?

Can anyone recommend a good product to use to try to plug a radiator leak?

I don't recommend any stop leak. Repair the rad properly and you won't be sorry.

BARS LEAKS

ALUMASEAL or JB WELD if you can get to it on the outside. Hey moose! you can get a whole new radiator on ebay for $24.99 plus $32.99 shipping. Item #8038923233 by the Radiator Connection.

Barsleak, Alumiseal, anything you put in your radiator to clog a "leak" will CLOG. Plain and simple, your pouring something into your coolant that clogs your system. You will not only end up cloging a leak, but the radiator, the water pump, the thermostat, and any other narrow passages in the block and head. You may was well pour sand in you radiator.

I ended up using the JB Weld option. The leak was tough to get to... in fact it was tough to locate... but once I did I was able to goop enough JB Weld in there to plug it up and it worked like a charm.

Yeah, JB Weld will fix almost anything. It is actually a steel impregnated epoxy with a hardener that cures in about 16 hours. It is good stuff.
