Can i solder a crack on my radiator to stop a leak?
Hi I’ve seen some pro’s solder a radiator up, but because of the thinness of the vanes it probably isn’t something you might do yourself. However a trip to Pep Boys or Auto Zone will turn up at least three or four product that you pour into your radiator and, unless you have Niagara Falls coming out of there, they have a reasonable chance of sealing it from the inside. Personally I have used one called Barr’s, but that might not be available in the States.
