1972 GMC Radiator Leak - 402 ci

Hello again - I noticed a crack in the upper area of my radiator that is leaking fluid after the truck reached temperature and I saw a few drops on the driveway. Anyone know if this can be brazed or repaired and then pressure tested and used again? All replies welcomed! Thank you! See photo

I would think a good radiator shop could repair it. Or an older more established shop might have a tank laying around that they could put on it.

I agree with Smitty.. It's an easy repair for a good radiator shop..

A shop can fix it, but so can high temp high psi epoxy, the stuff that comes in the syringe you can buy at the parts store. I punched a hole in a 1000rwhp corvette radiator years ago and my "quick fix" was some of that epoxy. It's still holding to this day.
