Hi I have broken my standard plastic/alloy radiator on my gu 2003 zd30. I broke the little return port next to the top inlet tried gluing a new plastic piece in and seems to be working but not confident in it lasting as a permanent fix. I have been quoted $300 to replace the top plastic tank but have seen all alloy radiators on eBay to suit my model for about the same money has anybody got one or would you recommend putting a standard one back in? cheers Mark
