Correct, it allows the oil the cool down in the turbo and allow the turbo to cool to keep the bearings from seizing. It is not a Factory item and is aftermarket only.

Thanks very much... Just wondered about these new trucks... My Dad was a trucker, and I have been a long time... I understand about letting a motor cool (turbo) before shutdown... Thanks again... Monkey

My point is you're better off starting a new thread. Those guys may not be around anymore, might not have the truck anymore, or never bothered posting the fix. Many never do....
Be descriptive, and include what you've already done to troubleshoot.
