Other than replacing the radiator, which is the best option, I have used the JB weld stick. It is any epoxy putty. Just knead it into a long cylinder, then place it into the crack. Work the putty into the crack very well. Do this when the radiator is cool, for best results. Max heat temp for this product is 300 F. So dont let it overheat. JB Weld stick costs around $5. Good Luck

Not sure if this will help but I have recently discovered that many plastics can be "Welded" using simple PVC pipe solvent.
