Coolant antifreeze leak 6.0 diesel.
 

'05 F-350 6.0 diesel, auto trans, 42,259 miles, rarely pulls a trailer or a load, stock and in very good condition. I bought this truck new Nov. '04. Todays date, 27 Nov. 2008. Now my first and only problem. I noticed on 25 Nov. 2008 that I have a large puddle of coolant under the truck. Only when the engine is totally cold does it leak golden colored antifreeze running down from what appears to be at the cylinder head gaskets at lower rear corners on both sides of the engine. My drive way is a slightly sloped black top and now with a stream of coolant running more than 30 feet out with a puddle the width of the truck under neath. The right side above the starter leaks much more than the left, a constant drip. 26 Nov. 2008 After adding one gallon of coolant mix up to the cold mark, I go to the selling dealer for this problem and an oil change and fluids check. The invoice tells me they replaced a hose clamp part number B7A*8287*AA, changed the oil and filter, performed the multi point inspection noting all fluids are full, that I have a week battery and one front tire may require future attention. I paid the 149 dollar and 50 cents bill and drove 7 miles home. Next day, today 27 Nov. 2008 my neighbor and his friend comes over to tell me they noticed antifreeze leaking from under my truck. At this point I will not mention to what agency in Ann Arbor, Mi. his friend works for but I will say that he was very concerned. Photos and a video have been taken. I raised the hood, looked around, found no leaks anywhere, nothing wet, power steering fluid still below the add mark, dark engine oil and a constant drip mess of coolant in my drive way coming from the same places as mentioned above. In the morning 28 Nov. 2008 I'll return to the Belleville, Mi. dealer to try once again to get this matter taken care of. Comments from any one?

Sounds like it may be the coolant line going into your EGR cooler.
