Overheating Diesel Pusher
Had the same problem-- worse-- two years ago pulling southbound grades on I-84 in Idaho/Utah. Triggered the high-temp alarm a couple of times.
Took it to Freightliner in Salt Lake, and they pulled a huge pile of junk out. Then the pressure steamer pushed so much impacted crud and grit out of the vanes there was a river of brown slurry running across the floor. Rock steady on 195* ever since- winter and summer.
