New to diesel - help needed

[steiny93]

what difference in routine unkeep / maintenance I would expect versus the 5.3/6.2?

during warranty
other than having to add DEF (either at the pump or via a jug) and a greater importance on fuel filter changes; maintenance is basically the same (both of these are in the dash)
in diesel land you will need to know which diesel to use if you live in a cold climate

after warranty is over (> 100k)
the gaser's will need spark plugs
the diesel's will need a timing belt

pretty much all the pain has been removed from diesel ownership

3.0l diesel has a timing chain not a belt. It does have a wet belt for the oil pump which has a 200k or 15 year life span per the diesel supplement.

rest assured, 'severe duty' will be applied to the belt, dealers will be quoting it at some crazy low mileage

And on the LM2, getting to that belt is intensive - something they addressed with the new 2025 engine.

Nothing new with the LZ0 diesel. It's been in the Silverado/Sierra since the 23 model year and put in the Tahoe/Suburban/Yukon for the first time in the 25 model year. The LZ0 3.0l diesel still uses the same oil pump drive belt as the LM2.
