A friend of mine own's a radiator shop here in town .He had a 05 CTD in the shop today to replace a radiator because the owner went over a dirt mound and caught the bottom of the core putting a hole in it. The truck has been down for 6 weeks because there are no after market radiators out there and DC is out of them!! Luckly he had a friend at the dealership here that got online and found 1 back east and it took him 2 days to find it . So be carefull out there or your truck could be down a long time.
