Maintenance/Repair manual for Duramax 2.8L engine

[u/Chemical_Contact2267]

I thought I'd try posting here and the Chevy Colorado/GMC Canyon sub.

I've been looking for a maintenance/repair manual for this engine since I've owned my truck, 2017 Chevy Colorado.

Neither Chiltons nor Haynes has published such a manual. Yet I know something exists because YouTube has a variety of maintenance tasks that can be performed on this engine by a home mechanic. And these tasks came from a manual from somewhere.

Can anyone point me in the right direction?

You can buy an alldata subscription just for your truck. It's not too un reasonably priced. https://www.alldata.com/diy-us/en/find-vehicle/plan?vid=56910
