Can a rad from an '83 auto be re-cored or repaired?
It is leaking on the passenger side near the top hose. Not sure if it is the hose (underneath) or the rad itself. In a perfect world it's the hose...but murphy's law tells me otherwise.
Another thing that may have something to do with it is that I have been using my heat as of late (it is Canada after all)

...anyway, it blows warm when driving, but if you sit for awhile the air gets cold...thermostat?? Could this have anything to do with the A/C not working at all in the summer?
Any help here would be appreciated!
Thanks,
Mat
