according to the new duramax specs listed on the other post, i have all of them, the new air intake design, the heads are different, the injectors are different then the previous duramax' and how it mentions w/ that kind of design the glow plugs light instantly, mine does exactly that, i have only seen the glow plug light come on once the other morning for a super quick sec.
And according to my dealer, my truck has the new duramax in it.

"New diesel engine:
An all-new version of the Duramax 6600 turbo-diesel V-8 engine will debut in the interim 2006 model year as an option on Silverado Heavy Duty models. When mated to an all-new Allison 1000 six-speed automatic transmission, the new powerplant will deliver more horsepower – 360 hp (268 kw) at 3000 rpm – and increased torque, at 650 lb.-ft. (899 Nm). The power increase comes with lower emissions and significantly improved quietness and smoothness.

The Duramax 6600’s horsepower and torque increase and emissions reduction are enabled by a strengthened iron cylinder block and a lower compression ratio. The lower compression reduces stress on the engine by reducing the peak cylinder firing pressure. This, in turn, allows more fuel to be burned – more fuel means more power – while the lower compression helps reduce NOx emissions. Lower compression also helps reduce noise and vibration, making the 6600 a quieter and smoother engine.

A revised variable-geometry turbocharger also enhances the driving experience of the Duramax 6600. Aerodynamic changes to the turbo’s impellers help tailor controlled application of turbo power for seamless and immediate response at full throttle. The turbo, which spins at up to 120,000 rpm, is high-speed-balanced, reducing vibration and resonance – and contributing to the engine’s overall smoothness and refinement. The revised turbo also helps reduce emissions, while maximum boost remains at 20 psi.

Another new feature of the Duramax 6600’s turbo system is the capability of the variable-geometry turbocharger to provide exhaust braking. This function is available on some medium duty truck models and can replace add-on exhaust brake hardware. With the new system, braking is controlled by a signal from the engine controller and can be activated by the driver.

The comprehensive list of changes and upgrades to the 2006 Duramax 6600 includes:
  • Cylinder block casting and machining changes strengthen the bottom of the cylinder bores to support increased horsepower and torque
  • Upgraded main bearing material increases durability
  • Revised piston design helps lower compression ratio to 16.8:1 from 17.5:1
  • Piston pin bore diameter increased to for increased strength
  • Connecting rod “I” section is thicker for increased strength
  • Cylinder heads revised to accommodate lower compression and reduced cylinder firing pressure
  • Maximum injection pressure increased from 23,000 psi to almost 26,000 psi
  • Fuel delivered via higher-pressure pump, fuel rails, distribution lines and all-new, seven-hole fuel injectors
  • Fuel injectors spray directly onto glow plugs, providing faster, better-quality starts and more complete cold-start combustion for reduced emissions
  • Improved glow plugs heat up faster through an independent controller
  • Revised variable-geometry turbocharger is aerodynamically more efficient to help deliver smooth and immediate response and lower emissions
  • Air induction system re-tuned to enhance quietness
  • EGR has larger cooler to bring more air into the system
  • First application of new, 32-bit E35 controller, which adjusts and compensates for the fuel flow to bolster efficiency and reduce emissions
The Duramax 6600 also has a new intake air heater to reduce smoke and emissions during cold or light-load driving. The system features a 600-watt grid heater located in the air intake duct, which is triggered automatically by the engine controller. It heats up the incoming air to speed warm-up of the engine."

Your motor should should the re-designed LLY. The "New Diesel Engine" or LBZ is not going into production until October at the earliest.

However, you should have the improved turbo, ECM, air box, fan, tranny, and ECT.

At work we just got an 2/05 so I would say its an 05 3500 D/A and its glow plugs only com on for a spit sec and goes off in the morning to. It must just be the new design. I know it can't be the LBZ and seems too early for yours to have it. I could be wrong its happened before.

Hey does your 06 still have the auto door locks that you cannot program to not lock?
