I had the same issue, and as I fixed one crack another would appear. Best option is to replace the radiator.

I do plan on eventually replacing radiator, but can't right now. What can I use as temporary fix?

I used JB Weld and allowed it to dry overnight. The cracks I patched never leaked again. Can purchase JB Weld at Wal Mart and it is not expensive. Mix and apply like you would epoxy.
