had an accident in the shop and ended up poking a small hole in the aluminum radiator.

Looking for suggestions on fixing this. Is this a JB weld canidate, maybe a welder can help me out....just wanted to know what you all think.

Thanks,

You can fix it yourself. We just use that JB weld stuff(there is another brand too that works). Just rub it together and smear it in the hole. Some recommend that you have to motor running and some recommend that you dont run the motor for a while to let it dry. Its an easy fix if its a small hole. Good luck

With small holes we've had great luck with the local welding shops, low heat with a torch then pressure testing them and we've never had a problem but if a person had much size in the defect and required much "filling" I'd not be quite as sure.

Mikey, I think I saw this stuff in Speedway motors catalog. It looks like weedeater string. All you do is heat the area where the hole is with a brazing tip until the aluminum is hot enough to melt the string. Let it cool to room temperature and go racing. I have used it before and I know it works. Even repaired a hole in one of the tanks that the radiator shop screwed up.

Any kind of epoxy will work. I patched mine with JB weld and it has been fine for 2 seasons, starting the 3rd.

I pinched it shut and put a gob of JB on it two days ago. It set up good and after a short run (5 minutes or so) it appears to be holding fine. I've got a back up just in case but I think as small as this hole was it'll hold for a while.

Thanks guys.

MOPAR sells a small kit that works great for fixing almost all but the biggest holes.
