From 2003 & up almost every diesel engine was designed to run with an EGR system. EGR being, Exhaust Gas Recirculation means it was a brilliant (insert sarcasm) idea to put exhaust gas back into the intake of the engine. It is possible that the EGR cooler which circulates your coolant thru this system is leaking. You won't see it externally because it is being blown out the exhaust stack. If it blows excessive white smoke out of the exhaust when it is first fired up I would recommend looking at replacing the egr cooler.
