Is that metal coolant line behind the motor covered under motor warranty?
 

Seems like it would be a cummins part maybe [laugh]. Dang thing is leaking from a welded joint it seems. Good thing I caught it leaving the deer lease had to jump someone off and noticed. Got a steady drip.

Radiator was full and the reserve was a tad low. Made it back to Houston ok.

Talking about the metal line that runs between the block and turbocharger? If so check the short rubber hose by the turbo for leaks. May want to replace the cheap clamps with some good stainless hose clamps.

It runs from the right side of the heater core then splits off. I'm pretty sure it's leaking from the split where it is welded and Y's off.

If it's not covered I'm gonna rough it up and put something like JB weld there. Wish I could solder it but it's on the bottom where it's leaking and it looks like an SOB to get off.

Take a look at this thread, post number 2, and see if that's your problem.

Yeah but I think it's leaking from the hard line. Maybe an illusion though and just running down from that hose the guy updated.

That hose was it, $17. Gonna put it on tomorrow.

SST hose clamps fixed mine!!!!!

Nope. Covered under the rest of the truck. I already tried.

Well I tried to replace that hose last week and have no clue how to get it off so I just tightened the existing clamps and it quit leaking. I put the new hose/clamps in the glovebox.
