This subject has come up different times in the forum. A number of the posts lean toward fixing it with a plastic welder. Those say it works.

I've tried the epoxy mix made specifically for that type of repair on a hairline crack that would pressure leak. It would hold for a while, then start leaking. I called a number of radiator repair shops around Des Moines. They all said they won't attempt a repair on the plastic radiator parts with any method because of comebacks. They all advised replacing the radiator.

Hope this helps,

I agree with Marbobj, band aid type repairs tend to let loose at the worst possible times.

If the crack is on the plastic housing only a new plastic housing can be put on the radiator. It would be a special shop that has the equipment to do this where as most radiator shop don't.
