How do I fix a jeep wrangler 2000 radiator, leaking at the petcock?

I have a jeep wrangler 2000. The radiator is leaking at the petcock. Is it possible to just fix/replace the petcock, or do i need to replace the entire radiator? If so, can you recommend where I can get an inexpensive radiator?|||Just replace the petcock, your radiator it's going to be just fine. Good day.|||you should buy a new one, they are almost immpossible to fix.you can always go to the junkyard for a used one, but they usually charge you just a few bucks less for a used one with no guarentee, you are always better off with a new one|||A new radiator is needed. The plastic tanks crack all the time.... Nothing you can do but replace the radiator... Also change the hoses and t-stat while your in there!!! Good luck|||throw that piece of sh!t away! it is a combination of a metal core with a plastic top and bottom. go on ebay and get a metal one for about 120 bones! if you can get a 3 core! dont go through the hassel I did, you will end up buying a new one anyway!
