I saw McGyver put 2 raw eggs in a hot radiator to fix bullet holes....

OMG... That just made me laugh hysterically.

Sorry soupy. I understand you're in a mess and waiting for helpful answers but the "McGyver solution" was funny... you gotta laugh.

Yellow pages for the local radiator shop.

I use JB Weld and have run several crashed radiators that have been repaired with this or straight epoxy with excellent results.

Just make certain you let it cure for at least 36 hours before using it.

Black pepper-like the kind you use on food. No joke. Just put some in the filler neck and run it for a little bit. Should take care of it.

If the core is brass or copper whip out with your electrical solder and a crack torch er I mean a propane torch.

Use a dremel to polish off any paint and get to some metal. It also helps if you make sure this puppy is bone dry before trying to fix.

on my 66 mustang 4 core radiator I had the fan bite a few cores. I cut out the damaged area. Pinched the tubes about an inch down and filled the fresh cut tube with solder.

Re: how to repair pinhole radiator leaks??

i too have used solder and a butane torch to fix a radiator. It was on an old jeep and the kids motor mount let go putting the fan into the radiator. We soldered about 20 holes in the middle of the woods, filled it back up with muddy water and it never leaked. He never even replaced the radiator and it's still not leaking 2 years later. Copper solders real well (obviously!)
