I don't have a clue where I'm losing it from yet. My first thought was the water pump but after finally getting it in the shop and looking it is coming off the back off the motor somewhere. Any help would be appreciated.

egr cooler looks good. No leaks off of it. Any other ideas. i've checked all around the turbo also and can see no visible signs of coolant. But where on the turbo are the coolant lines.

There is a pipe that runs coolant along the passenger side that attaches to the front side of the block that has a tendency to break at the weld of the bracket. It would be hard to notice but it happens a lot. Check out this coolant pipe.

welcome to the coolant leak club! at least you can see that yours is leaking. i cant find any trace on my truck. ive been super slammed with work though so i haven't been able to really look into it.

the coolant line goes into the turbo from the passanger side of the valve covers into the bottom of the turbo. it returns out of the drivers side via a little black hose attached to a cone looking metal piece under your metal tube going from the thermostat to the upper radiator.

Is it running down from up high or what? There's a plate on the right side of the flywheel housing that blocks off the coolant passage in there. It has a metal gasket that may be leaking.

I'm just trying to think of things over there that could leak. I've never seen or heard of one leaking, but you never know.

I don't think it's that big of a deal. It's just forward of the bellhousing on the right side of the motor. I'm not sure how hard it is to get to with the engine in the truck, but I doubt it's that bad. Should be a little above where the starter bolts in.

You might be on to something cause ive noticed a little on the starter. But what gets me is how did it get onto the centerlink. Maybe ran down the oil pan?

I don't know. I would almost guess it is coming from somewhere in the front, maybe that coolant pipe that someone mentioned breaking at the welded bracket, and blowing to the back of the motor, but you said it is leaking from the back when it is pressurized.
