The 6" long 4" dia. hose fwd of the intercooler tricked me, as it was so pliable, I thought it was ripped. Close inspection after wrestling it out showed it orange and okay.. drat- wasted effort.!

Having read many threads about elbow hoses, I looked and found it, driver-side of Cummins, hidden by fallen compartment insulation (Yaay, another project!)

Pics show rear of coach, then a look inside to the site of the elbow hose, I t was somewhat melted to the metal hoses on both end, not rare, and I finally sliced one end to wrest it from its "home". Yup, blue hose; the lo-temp one and kinda shot!

No part number on it, so I'll have to re-find it in a posting, and order.

Looking at your second picture, it difficult to tell if you have clearance between where that hose fits on the 90 degree coming off the turbo and the body shelf, remembering that there is a little movement there as the engine moves slightly on the engine mounts.


On our 2003 38FDDS, there was NOT sufficient clearance and contact took out not only the hose, but also that 90 degree AND the compressor side of the turbo.


If there is even a possibility that you have an issue, just remove the clamp from turbo to that aluminum 90 degree to which that hose is attached. Verify that the joint is "air tight".



PM me your e-mail if you want pictures-- an expensive fix.

Thanks, Brett. I'll take a closer look, with added perspective. I was surprised by the amount of cooling air passing over the area after my work.

Both check for prior damage AND verify that you have at least 2" clearance between anything engine mounted to "fixed parts" of body and suspension.

All I know is that I replaced all of my blue hoses.
Yes, it's tight but I did it from underneath and with the bed up.
It is not that hard. I also had clamps rust and brake.
I carry 4 extra clamps -- get them from NAPA

Don't overlook that he said CONSTANT TENSION clamps, not screw type.
