I messed up, I broke the tube for the overflow when I was changing a harmonic balancer a few weeks ago. it is right there below the radiator cap, and the rubber hose leading to the overflow tank clamps to it. I can't take the radiator out to have my local radiator shop repair it, so I am going to have to fix it myself. I think that it is brass, so can I solder that back on?? A friend of mine told me that using silver solder should work, but I am not a soldering/welding expert, so I figured I would post up here to see if anyone has some suggestions or knows the proper way to perform this repair.
