Can a cracked plastic tank at the top of a radiator be fixed or must you replace the radiator?

Replace the radiator.

Try JB Weld or JB Kwik Weld on the crack first -- you can pick it up for $4 and it is definitely worth a shot.

I have tried the jb weld it didn,t work . I had to buy a new raditor

I work in a shop where we routinely replace the plastic tank. If you have to repair the plastic tank then do it from the inside. You can separate the tank from the core by carefully loosening the aluminum tabs holding it in place.

A cracked radiator can not be fixed. A cracked radiator needs to be replaced . A mechanic can replace one in a few hours.

Usually a radiator is made of metal. Plastic can not take the pressure. A hole can be fixed by welding. A radiator shop can tell you for sure.

You don't! If it is cracked all you can do is replace it. It would never be safe enough to put on the road. At least if my family was to ride in the vehicle.
