    455 mower - radiator crack

    I have a 455 that is overheating due to a crack at the top of the radiator just behind the cap. The top part is plastic not metal. Can this be repaired with JB Weld or will I have to replace the radiator?

    If it was mine since it isn't any good this way I would clean the crack and sand a little around it. Then use JB Weld to put a gob over it and put a patch of same kind of material on top of it. You could cut some black plastic off a old car part if you need to. It will work and last many years if you also band aid with the plastic for more holding strength. People have fixed manifold leaks with the stuff in the past. I have used it on a fuel tank still holding. Besides JB Weld is way cheaper then a new JD Radiator.

    I would try a radiator repair shop if you have one in town. It seems to be a lost art form but in the past, you could have the end tanks replaced.

    Buy a plastic welding kit. They start at around $60 and work just fine.
