Currently getting trained on the 6.7 at the Charlotte Training center

I've got 2 days down, tomorrow is my last day of training on the new 6.7. It sure is an interesting motor. It looks packed under the hood, but with the quick removal of say the intake air tube, you can put your hand on the majority of the engine. Engine does have 2 separate cooling systems. 4 Thermostats, 2 radiators, 2 reservoirs practically everything is liquid cooled. The Diesel Exhaust Fluid is 32% Amonia and 68% Water. I suppose you could pee in the DEF tank and the engine would run on it.

If anyone has any questions, i'll see if I can answer them.

They really made this engine A LOT simpler, imo.

Oh, and lets see, the regular version of the truck has a wastegate and no more hydroboost. It's got a vacuum assisted brake booster.

Well, the PCM doesnt know what is in the tank. What it does look for is if there is a change in the emissions when the DEF is injected. If you were to say put water in the tank, it would see that it is causing no change when it is injected into the exhaust. And it will set a message on the instrument cluster saying that the DEF is contaminated. The DEF smells exactly like cat pee.

We were told that there was a group of engineers that drove something like 7 different trucks from a point A to point B and a dually with a thousand lb payload made 32mpg. That was the best of all the trucks though, so who knows.

Everythign on the engine seems very simple. Except for the cooling system ofcourse, but it seems like they did a LOT of trial and error to make it work. The upper intake takes like 12 bolts to get off, and the lower intake is another 8 or so. The high pressure fuel pump is in plane view in the center of the engine in the valley, its not 'inside' the motor.
