I let my foot get off into the throttle a lil too hard this mornin, and somethin gave. I noticed a cloud of white smoke and smelled coolant. When I pulled over it was pouring coolant from around the back top center of the engine. I can see my egr delete hose and It's not leakin.. Best I can tell it looks like some coolant is comin from a metal pipe that looks like its corrugated.. I've attempted to upload a picture.

That looks like an up pipe, you sure it's coming from that? The pipe carries exhaust to the turbo. Can you look under the turbo and see if it's wet there too?

Check the coolant line running into the cab. They are for the heater core, check the plastic connectors.

The lines going to and from the turbo should be easy for me to find. A co-worker diagnosed it as the heater core hose, but I couldn't find the heater core lines earlier. I was under the hood and the trans. Thank Y'all, I'll check those spots out first thing in the mornin....

Dan is probably right I have broke one of them as well in my truck and fixed tons of other peoples. They get brittle and break pretty easily. If it's that you will need a disconnect tool.

It's would be these two hoses going into to firewall.

I'm 99% sure that it's not those connections that are leaking. And yes i do have a broke motor mount. I usually go through about two sets per year...

It might seem impossible, but for good measure I'd check the hard pipe that goes into the thermostat very thouroughly. A leak anywhere on the front of the engine will get blown and pushed everywhere and can be difficult to iaolate...just a thought...

If you remove the intake horn you can see the turbo coolant connections easier and probably where I'd start, after checking the T-stat housing and other quick visuals

Need to use a leak tester they work great. Depends how big the leak is. You screw it on the reservoir and you pump it up like a keg tap and it will push coolant/water through the hole you have the leak. You may be able to rent one.

My rig usually weighs over 11,500 lbs when I break the motor mounts. This is because it normally has a custom welding bed, a diesel 250 amp Lincoln Weldin machine, two bottles of oxygen, a bottle of acetylene, and tools on it.

Thank Y'all Very Much, I'll check those spots and let y'all know as soon as I get time.

I finally fixed it, then heater core fittings are a booger to get to... But that's all it was... Thank ALL of y'all for the help. I really appreciate it.

That sounds like hard work...
Smarter/lazy man way.. I plug off the 1/2" hose coming out of the radiator and plug this into the 1/2" hose coming off the expansion tank
Made mine out of 3/8" npt stuff.... Got the gauge from Napa rest is air compressor stuff and barbed hose fittings... I have swapped barbed hose for AN to npt to chexk fuel tank for leaks
