6.7 Coolant Leaks
I have a coolant leak somewhere on the top of the engine running down to the oil pan and bell housing. I have done some research and discovered it could be the coolant inlet tube to the turbo. Anyone else have this issue or a coolant leak somewhere else I should be looking? Thanks

RWC, when you experience the leak, do you smell the coolant burning/heating on the engine?
I recently had my 2011 in the dealer due to an odor entering the cab. I would only notice the smell when coming to a stop or when pulling into the garage. It was not always present, only certain times. The dealer service underwriter said I had a coolant leak beneath the turbo, so I am guessing it is the same connection you mention and the same as shown in the video posted here.
Just wondering if you would smell the heated coolant in your situation.
Thanks.

I had one leaking for two days last week appearing to leak from my primary water pump. I could smell it and I could see it leaking down onto the track bar. But it mysteriously stopped leaking. I'm sure it'll be back in time.

And funny you mention that Keith. I have replaced SEVERAL leaking radiators on these trucks and only ONE leaking turbo fitting, and I probably see far fewer trucks than you.

RWC, how much coolant does it leak? Enough to drip on the floor? I saw a light coating of something on the bottom of my oil pan, and a little on transmission housing, but no drips. Figured that it was remnant of the coolant that spilled out when I installed engine block heater. I better check again to see if there's more now.

I failed to mention in my post above, that the fumes/odor happened intermittently, and only noticeable when coming to a stop. I never experienced any dripping on the garage floor. Perhaps because whatever leaked burnt off on the engine - causing the fumes.

Typically the leaking coolant is slow enough and in combination with the heat from the turbocharger it tends to evaporate quickly leaving a buildup of crust around the fitting. We have shared a few pictures on the DTS website and some leak long enough to create an impressive crusty formation. Eventually the leak gets progressively worse leaving a trail of dried coolant residue down the back of the engine and presenting a drip.

Did you ever have to replace the water pump? Reason I ask is because my heater in the cab stopped blowing warm/hot air today when idling or when I come to a stop. But while driving on the highway it worked fine. So when I got home I started searching here for causes and came across this thread. Coolant level in both reservoirs looked completely empty. The truck has never ran hot and when I got underneath I could see coolant running down the track bar, It looked like it was coming from somewhere around the lower hose housing on the drivers side. Not sure if that is where the water pump is on my truck or not. Is the water pump the best place to start in this case or should I be looking somewhere else.
Thanks

Yessir, I had it replaced under the powertrain warranty at my local Ford Dealer. They had it in and out in a day. Mine was leaking at the same spot. It was dripping down onto the track bar. But, I never lost as much coolant as you. It was just a steady drip. I have also heard of people having hose failures, but not exactly sure where. I had my water pump replaced at approx. 40,000 miles.
