eBay
Large Used kart radiator for sale.
Core doesn't appear to have cooling passages punctured, mostly fin damage from use. These radiators are built strong & made to efficiently cool the engine.

All of my kart radiators I am selling on eBay hold pressure!
Radiators were pressure tested at a local radiator shop on 3/20/14.

Check out my other listings as I have many other parts I could bundle such as shifter kart radiators or other miscellaneous items. 
I treasure my PERFECT eBay buyer/seller rating. Same day shipping is likely if purchased before noon CST. Will be professionally packaged. Any questions please let me know.
