Found a coolant puddle under the front of the block on my 2007 6.0 today, about 1/2 a gallon. Upon inspection of the engine bay, the only coolant I found was around the mounting flange for the intake elbow, but I'm not sure how that would be leaking coolant. Also, at idle this morning there was only cool air coming out of the vents with the heater on full blast...this was after 10-15 min of warmup and a 15-20 min drive (interstate) to work in about 40*F weather. I thought the thermostat might be stuck open making the vents cold, but due to the coolant on the ground I feel I may have bigger issues...thoughts?
