The Duramax 6.6L Turbo Mixes Beautiful Innovations and Beastly Resilience
Equal parts brute force and high-tech performer, the Duramax 6.6L turbo diesel is both powerful and ruthlessly efficient, featuring:
• Aluminum cylinder heads, engineered to help reduce engine weight. This design also utilizes six head bolts and four valves per cylinder to create the extraordinary head-clamping strength needed in harsh turbocharged environments.
• Pistons without pin bushings, engineered to cut reciprocating weight while offering quicker engine revs and throttle changes. This setup also benefits from piston-cooling jets situated at the bottom of the cylinder bores, providing extra lubrication to help reduce noise and friction and help with engine life.
• Innovative cylinder block and rotating assembly built for durability and smooth operation. Block construction uses a cast iron foundation with induction-hardened cylinder walls. Cutting engine weight is a die-cast aluminum lower crankcase surface-hardened by nitriding, a process industry professionals call the best way of curbing wear.
• Finally, a variable-vane turbocharger uses state of the art electronic controls and self-adjusting turbine vanes to pump out additional power with no loss in fuel efficiency.
Think of the Duramax 6.6L turbo diesel as a bronco-busting cowboy with a Ph.D. Think of it too as one option in the Duramax diesel family that currently has more than 1.3 million engines hard at work. With history, experience and exciting technological advancement like that, leave the fantasy stuff to the kiddies.
The 6.6L is available as both a new (PN 12638502) and remanufactured (PN 19302836) long block service engine for 2010-2017 model year full-size pickups like the Silverado and Sierra and full-size vans such as the Express and Savanna.
