Isnt that what this is for? To increase coolant flow to #5 and #6 cylinders?

Herb, I can not say that will prevent it from happening but at least you can "check" that off of the list so you know that is not what caused it.

And harry, that does not seem like a bad idea but I am going to wait a little bit before I do that. Now that it is getting cooler my temp is no longer going between 185-215 constantly. It stays right at 188-192 :5:

Mine has never got over 190 since I put the Rokk timing advance on it, use to run at 200 before that, but the bypass sounds good too, can't hurt.

Yeah, I don't want to scare you or anything Herb. I'm not not every 04.5 and 05 has that problem. I just wanted to send out a warning from what happened to mine.

I am also going to look more into that bypass and check it out! That thread is a little messy though on the subject.

Herb, Will that timing sensor from rokk tech interfere with other tuners that adjust timing with their own program? Just curious...looking up the rokktech sensor right now, first ive heard about it.

There is another bypass kit. Its called the opie bypass kit if you wanna look it up and compare notes.

You can back off the rokk sensor, but pushed all the way up is 2 degrees and you can back it off using pieces of black tape, each layer is a 10th of a degree for custom tuning if needed.

The Rokk Tech sensor is 'physically' moving the crank position sensor. It will always add what ever timing it is positioned to. Don't run it with other 'tuners' that add timing as well or you could easily have too much!!

To answer your question-yes, the 4WD pan is relatively easy to pull. The 2WD MAY be doable, but you REALLY have to lift the engine to get the pan off-the cross member is almost against the pan.

After 2002, Cummins will have NOTHING to do w/ our engines.

Cummins told me that Dodge bought '03 and up engines from them with NO WARRANTY at all.

"You're on your own" is what Cummins told me.

They also will NOT work on the engines unless you sign a release saying that you understand that they do not have any of the electronic specs for the engine management system. It seems Dodge refuses to let Cummins have any data on the injection system.

The local Cummins shop wanted $6000 just to pull the engine and open it up. No thanks!

I fail to see how such a dysfunctional "marriage" of chassis builder and engine builder has lasted this long!

wow just wow, an i wanted to buy an 03 common rail, sorry to hear this guys

Hard to believe Cummins would let Dodge run their image down by trusting them to take care of customers, never mind letting them design the engine management system which could make your engine look like shit.
