You couldn't give me one of those new GM "ValueMax" I6 diesels. Some dumb#### at GM signed off on a
belt drive oil pump with an expected 150K belt life. "Like a SNAP!" failures under warranty while you wait for the locked up Scrap Metal to be replaced with an engine. "Just slide the trans back to change the belt."

Anyone recall the timing belts on Ford escorts and VW diesels? Cut the bolts on the Escort engine was faster to pop the head off after it broke the belt in an intersection: they always snapped in an intersection...
All aluminum with several low bidder "valves" in the cooling system to tempt the "What could possibly go wrong?" gods. It's a good thing the Olds 5.7 diesel put lemon laws on the books because "here we go again" with another life limited by design and cost GM diesel engine. This is on top of the fixed life expensive injection system and emissions parts.
$9300 option charge for a 6.7 Cummins is around 3x the GM option charge for the I6. Cummins will hold it's trade in value better than a 150K mile value engineered engine. Time FCA made a big 3/4 ton SUV with a Cummins. Just delete the pickup bed and add a trunk...
In depth info that makes one realize these ain't intended to go 250K without $major$ maintenance work.
