How should I fix my radiator?
 

Fan chucked a bolt into my Koyo radiator.

I work at a fab shop, so I have access to everything I need. Should I be able to weld this shut in the car or should I take it out and cut an acceess hole in the end tanks and weld off the tubes from both ends?? It really sucks to fuck up a radiator that is only 6 months old.
