Exhaust Fluid

Thanks, Soundguy.

Topic at hand is Exhaust Fluid.

If so then why are you asking about an old Cummins block that had nothing to do with exhaust fluid...?

Are you sure the DEF tank was FULL upon delivery? I'm assuming you have a new Ford, since there is no DEF gauge you don't know exactly how full it is. Message screen just says "OK", under half or count down to empty. Dealers have been known not to top off the DEF tank.

I am talking about a Peterbilt semi truck. I know the DEF tank was full because I filled it. It does have a gauge in the cab just like a fuel gauge. The problem ended up being the hose fron the DEF tank fell off. I was loosing the fluid going down the road. Didn't notice the leak because it was dark when I started having problems. Its pretty bad to have something like that happen in the 1st 300 mile of the trucks life. I am begining to think all the new engines are junk. 6 hours at the dealership and I was back on the road

Navistar is still trying to go without exhaust fluid. They are having a tough time of it. They were sueing the EPA over it

Deere's large ag tractors engines were able to pass without exhaust fluid for now under Tier 4 Interim.


Navistar loses EPA court case - discover Diesel Exhaust Fluid (DEF)

Navistar was allowed to use up the carbon credits they had built up over the years and are running out come February. They sued the EPA and lost, over the fact that the trucks with DEF could actually run without fluid and pollute. The fact is they keep derating the lower the fluid gets and speed is reduced till the point that it will shut down.
The benifits of DEF and the cost savings, out-way the cost of the DEF.

No, eventually they will all be required to mert Tier 4 final.

I'll take the SCR/DOC set up over cooled EGR any day.

There is one thing we can finally agree on without question.

which one had the killer dowel pin ?

First gen rams, i think all 12 valves. I know early second gens had them. If fiat would shove an iveco under that hood, they would not need cummins.[/QUOTE]

Give it time, it can't help but happen. There's no reason to outsource engines when they have their own Tier IV non-structural block engines.

Any ideas if there is anything under the hoods, either in Europe, or being tested?? MB had a diesel ready for them,but guess that got quashed when Chryco was sold.

If I ever go diesel, Duramax will be my choice, SCR is the biggest reason, the Allison is second.

I haven't heard anything along those lines, but I'm not a truck guy.
I think of cars & trucks as necessary evils, not topics of interest.

I highly doubt Chrysler would drop the Cummins for an in-house diesel solely due to the history and cult following it has. I am however very confident you'll see a Fiat based light duty diesel in the next light duty Rams and Jeeps as well as the Fiat based work vans coming over.
The MB blu tec diesel was used in the Jeep Grand Cherokee but not a good enough seller to continue and could not meet new emissions.

Fiat already created a V6 3.0l diesel (237hp/410tq) for the Jeeps abroad. That engine with an 8-speed tranny would make a nice 1/2 ton RAM.
