Anyone know where this coolant could be coming from? I drove up into the mountains this morning, about 1 hour of mountain roads and climbing. Was not pushing it to hard, coolant temps were around 216 degrees. A few hours after reaching my destination I noticed something leaking from engine, it was coolant. Removed doghouse and noticed dried coolant residue on top of engine, particularly on turbo, only on drivers side but clearly had been sprayed all over. I'm guessing about half a gallon of coolant is missing from the degas bottle.
At this point the engine was completely cooled down. I started it up (doghouse still off) and let it run until coolant us at normal running temp (190 deg). No sign of a leak and no steam or coolant smell coming from exhaust. Put everything back together and drove down the mountain and home (about a 2 hour drive). When I got home more coolant was dripping from engine.
It did not look like it is coming from EGR cooler as almost all of the coolant residue is on the other side of the engine. And Oil temps and coolant temps were never more the 8 deg. apart on the drive home.
Does the turbo have coolant running through it?
BTW this is a 2006 6.0 Diesel.
Any help in pin pointing this leak would be appreciated.
Cheers,
John
