2500 Coolant Leak
RED,
I had a coolant leak on my 07- 5.9. There is a small hose on the passenger side of the truck back by the turbo. The hose (silver in color, foil wrapped) comes from the factory a little loose, when it gets cold the metal contracts slightly and the small drip occurs. Tighten the hose clamps a few turns. This should solve your problem, it fixed my truck.
Please see the pics for the hose location
Hope this helps
