Radiator cracked, need help!

Okay it is hot as always in texas, but anyways, the radiator cracked right at the cap. It's about 2 inches long. I wonder if there is any type of glue besides Epoxy(which didn't work) that i could put on it to keep running the car without having to put in a new radiator. And also if i do have to get a new radiator, can i just get the top part?? Help would be greatly appreciated. Oh yea, it's an 88 accord, and not mine.

JB weld epoxy? that will probley work although i'm not shure how well it will hold up against the heat.

Make shure the area around the crack that your applying the epoxy to is clean and has a good rough surface.

By top part, you mean the 'tank'.
If the upper and lower tanks are plastic, it is possible to get the upper tank, remove the old one and re-crimp it on to the radiator core. However, this is a lot more trouble than installing an all new radiator, and unless you are familiar with the procedure, can leak everywhere.
If the tank is brass, it might be possible to have a mechanic braze or solder the crack closed, but if the metal is fatigued, the crack may still open up more.
Seriously, radiators are cheap. Bite the bullet and put in a new one. If you really don't care for the car, try getting a good used one at a wrecking yard.
