Yes, I am just full of questions today. Was wondering if there is an easy repair for a cracked seam in my radiator? It's a small crack on the side, but it has no problem squirting out anti-freeze! Am I better off taking it to get repaired/replaced, or is there something simple I can do to plug it up? Thanks in advance!

If the crack is easily accessible, you could tig weld it. If not, you should send it to a radiator shop. There is also a fluid available at some auto shops that has beads in it that 'plug the leak', but I wouldn't recommended it. One of those quick fixes that doesn't necessarily work...

You could solder the crack.

You could solder the crack.

I would think using solder wouldn't be strong enough against the pressure and heat. Has anyone ever done this with good result?

For small cracks and leaks especially where the welds are on the radiator i have seen a lot of ppl mix up some JB Weld for a quick fix. My buddy JB Welded his and hasnt leaked yet and that was about 4 years ago.

I have soldered radiators it works fine as long as the surface is nice and clean.
