Couple quick things too watch.
The turbo / intercooler tube boot ring that's crimped on popped/blew off mine. Picked up a positive pressure clamp at the Kenworth dealer to fix.
Also there is a hose behind the right headlight that's connected to the trans cooler/ auxiliary tank . It's hard to see my spring clamp broke there and it had a small leak then blew off finally.
Two small simple fixes that could strand you on the road side.

Had a hose clamp luckily , otherwise was in the middle of nowhere West Virginia .
I'm guessing Five hundred dollars for a tow and fix to install a dollar ninety eight hose clamp.
 
New fix /issue . Been fighting intermittent no crank for a week and a half .
Found the start fuse was not seated good , starts . Next day no crank .
Finally fires up then dies with no crank .
Turns out the start run relay failed . New relay vroom vroom .
 
Depending on model year those cac tubes have extended coverage on them. Up by the emergency brake lave there is a large 70 some odd pin connector discount it make sure clean and dry and if your local parts store has connector stabilizer apply a small amount and reconnect. I do not recommend dielectric grease. If available clear all codes. We have been seeing this problem more frequently lately.
