heater core leak

I have a small leak in my old trucks heater core. instead of trying to find a new one, i would like to find out if anyone knows of anyway to repair this one. i have been told to use Bars leak to jb weld. would like to do something other than find a new one and replace. Thanks Fletch

Bars Leak is the way to go. Make sure you read the instructions. I've used it in radiators that were pouring out a stream 1/8" and larger.

JB weld or other epoxies would only work if the leak were on one of the tubes and if it were there you could probably solder the break.

Good luck

Why not replace it? All the money is in the labor. The core itself isn't all that expensive. Don't try to put any sealers in it. All you'll do is plug up a lot of things you didn't want to. You'll end up with more problems than just a heater core.
