AutoBlog: REPORT: GM halting Duramax production for 10 weeks

Recommended Posts

Filed under: Truck, Plants/Manufacturing, Chevrolet, GM, GMC, Diesel


The revamped 6.6-liter Duramax V8 engine will go into production in April 2010 and the current Duramax, which doesn't meet emissions requirements that go into effect January 1, 2010, will cease production the day before the new year begins. In the interim, GM will be retooling the factory and won't be producing any of the engines to go in the Chevy Silverado and GMC Sierra.

This has some dealers and outside observers wondering if GM will run out of 2009 Duramax engines before the new ones are built and installed in engine bays. One dealer says GM will take orders for extended cab models with the big diesel, but no longer accepts orders for Duramax regular cabs. Analysts believe that with the car and work truck market showing some recovery, that demand will grow just as GM is trying to play the inventory game.

While the General prepares it's urea-infused powerplants, any engines that GM builds through the end of 2009 can be installed in vehicles even if those vehicles are ordered and built next year. For now, GM says it is padding its stocks of Duramax engines and is confident about being able to meet the need.

If I were ready for a new truck, they would lose a sale.

I can't understand why they would restrict the Duramax in a regular cab truck. It makes no sense as many,many, work trucks are both diesel and regular cab.

Seems silly to me.

urea injection

Urea plays an important role in the metabolism of nitrogen-containing compounds by animals, and is the main nitrogen-containing substance in the urine of mammals.

Automobile systems

Urea is used in SNCR and SCR reactions to reduce the NOx pollutants in exhaust gases from combustion, for example, from power plants and diesel engines. The BlueTec system, for example, injects water-based urea solution into the exhaust system. The ammonia produced by decomposition of the urea reacts with the nitrogen oxide emissions and is converted into nitrogen and water within the catalytic converter.

I believe you have to get the urea refilled every oil change IIRC.

With the market as down as it was and not recovering fast this may be a good time to make the change.

Dec- Jan-Feb sales are slow even in a good year.
