It cracks me up Chevy puts out a diesel engine that needs all of these areas improved and when they improve them (cause they are failing) Chevy thinks they are doing something superhuman. Why do Chevy owners like being guennia pigs?

FROM CHEVY WEB SITE

-A smoother and more efficient turbocharger
-Quieter air induction system
-EGR with a larger cooler for more airflow
-New 32-bit E35 engine controller for better efficiency and lower emissions
-Added a 600-watt grid heater in the intake to reduce smoke during cold and light-load driving

Why don't they just buy a Cummins??

 

Again I'm confused (doesn't take much), do they now have glow plugs AND a grid heater??

Is it that hard to start one of these up? I never even plug in my Cummins and it will still start after sitting for a week in below 0 weather if the batteries are good.

Ignition system: compression, glow plug start aid; low-resistance spark plug wires
