Putting The “Eco” In Ecodiesel The new EcoDiesel V-6 achieves 50-state emissions compliance for both tier II and BIN 5. A key enabler is the engine’s cooled Exhaust Gas Recirculation (EGR) system, which is controlled by electric valves instead of the conventional pneumatic variety. The system also contributes to rapid start-up. A state-of-the-art Selective Catalytic Reduction (SCR) system also reduces emissions. It incorporates aunique Diesel Exhaust Fluid (DEF) system that, unlike competitive systems, alerts the driver to low DEF levels while also allowing the engine to maintain full power. Other features include: •An insulated DEF tank with heated lines mitigates the effects of cold-weather operation •A passive cooling system (one that does not require engine coolant) for the DEF injector •Exhaust-system refinements to improve the utilization of DEF for NOx reduction while also mitigating harmful DEF crystalline build-up •An exhaust-system design that requires less energy from the engine to achieve optimal emissions conversion temperatures •An exhaust-system strategy that reduces soot output while also improving fuel economy and meeting emissions standards The DEF tank holds eight gallons of fluid. Duty cycle determines refills, but the average interval is about 10,000 miles. DEF is commonly available fuel stations and is also offered by Mopar, Chrysler Group’s dealer network and and Cummins dealers and distributors. The standard engine oil cooler, when the EcoDiesel is used with 5W30 synthetic oil, contributes to a 10,000-mile oil-change interval. The use of B-20 biodiesel is validated and approved for the new 3.0-liter EcoDiesel

Keeps full engine power even when it's low on def unlike other diesels.
I'm supposed to be getting my Ecodiesel back tomorrow after the service engine soon light came on and they found that the DEF tank outlet had crystalized. There are no tanks and Chrysler is supposed to pull a tank off the assembly line. I convinced the dealer to get one pulled off another vehicle. The service manager is driving it tonight to make sure, and if all goes well, I'll get it back tomorrow. The light came on after driving it 25 miles off the dealer lot. I hope this was just a bad tank and not indicitive of the tank design.

I'm looking forward to having my 1 day old truck back after 2 weeks in the shop... Let's hope I got all it's shop time out of the way up front :D
This is a great explanation of how it works. Thanks for this.
Dieseleco - You get the award for first "weird" breakdown.

DEF tank outlet crystallized??? Wonder if it's the fluid in the outlet or the actual plastic tank or fixtures that failed? Never remotely heard of anything like that. You are a "first" and hopefully "last".

Good attitude and Welcome!
