There's that old style EGR cooler hose to consider also, though it usually makes itself known by leaking down the back of the motor. Do you by chance have your truck parked with the nose downhill?
I have seen this issue this past weekend, is there anything I should do to remedy?
Actually, I have seen a leak from the back of the engine falling off the tranny bell housing on the right and left side. It is yellow green coolant. I cant see where it is starting from without tearing into it some. I was parked with the nose sligtly downhill after pulling TT. Only appears when engine cools down (no apparent leak under pressure as we drove home on Monday with no change in coolant level or temperature warnings). Still leaking about 2-3 tablespoons (just a guess maybe less) but only overnight.
