While towing my 5th wheel yesterday in stop and go traffic, I noticed the temp gauge start to climb. As it neared the top, I pulled over immediately. I let it cool somewhat to check the degas and it was nearly dry. I refilled and started the truck and noticed a massive leak under the engine compartment. Luckily, I was relatively close to home and was able to have someone else tow in my trailer and I trailed the truck home. My brother in law said his had a similar issue and it was a small hose on top of the engine almost under the turbo. I haven't torn into the problem yet. I like to post here first for advice before I do expensive explorations. I can defititely see and hear steam coming from the center of the rear of the engine near the turbo.
The EGR has been deleted for years and the oil cooler replaced. The EGR delete was a based on a EGR delete kit.
Before tearing into it, does anyone have any suggestions as to what the culprit most like may be? If it is the hose my B-I-L was referring to, does anyone have an official name for it?
The vehicle is an 04 6.0L PSD w/ 178,000 mi.
