The radiator on my brothers 4 wheeler sprung a leak last weekend. It wasnt punctured or mistreated. He took the radiator out and took it to a local radiator shop. The guy inspected the radiator and said it was just shot and couldnt be fixed. He then called the local Kaw. dealer for a price on a new one. Can you believe $590 for a radiator, WTF. Where online can this be bought cheaper? The machine is a 2003.

You could try Ebay but could wined up with the same problem.
Hope this helps

this site shows it out of stock but that may be due to the radiator may have to come from the factory. I have ordered many parts for my prairie from these guys, best deals i can find online, plus fast shipping if items are in stock. they show the radiator for $453.29 free shipping i believe also.
good luck
