Radiator repair

[Grant Lenahan]

I think the first step is to determine the cause of the leak - specifically is it a bond that is failing, or a crack/break, and if so, in plastic or in the metal (due to corrosion or fatigue).  Once you know that you have a better answer….

If its just a leak where the two parts go together, it may be possible to dis-assemble and put in a sealant or high temp glue.  If its a crack, its more complex, or so I would guess
