I replaced my TD5 rad after puncturing it greenlaning a couple of weeks ago. I got a new one from Island 4x4 for about £115. next day delivery.
Is it OEM ? ... who knows, it fits, it works and the engine runs slightly cooler than before... maybe the old one was full of mud!
After a few calls the only thing I came up with was that the cooling system was too efficient so the oil cooler connection was blocked off to allow the engine to get hotter, the pipe connector was left there to avoid any re plumbing, somehow the letting the engine get hotter bit sort of goes against the grain
