2004 and 2004.5 - Dodge Diesel

djdc · 11-14-2008, 11:52 AM

How can I tell the differences between the two trucks.

2004.5 has a cat converter on the stock exhaust and the 600tq motor. 2004 would have the 305hp/555tq motor and no cat converter on the stock exhaust.

04.5's have a cat the 04's dont
Exhaust on the 04 in 3 1/2 the 04.5 is a 4 inch
should be a sticker on the valve cover if it is 305 or less it is a 04

look for the sticker, not many people change that, never ehard of one gettin changed, exhaust systems don't tend to stay stock for long around here, and lots of cats run away.

The build date inside the driver side door is after 1 Jan 2004.

Thanks guys.
The reason I asked is because, I found an 04 the other day(totally stock). The build date was AUG 2003. I figure that it was an 04 and not 04.5.

Now from what I've heard, the 04 get the best fuel mileage. Any input you have, would be welcome.

I'm happy with my 04......look and see if the LP has been retrofitted to the in tank newer version. I'm getting 22.7+ in town with my new tranny.....hand calculated.

The 04 does get better milage, but the 04.5 is easier to BOMB!!

How so? Just wondering not arguing.

Nothing wrong with a pampered 04. I got the 04.5 because that is what the dealer had when I made my deal. I am sure I would have been just as happy with the 04.

the spray angle of the injectors is changed as well as the bowl shape on the piston. the bowl is much wider than that of the 03-04. this allows for a longer injection event which means more fuel in the cylinder.

Thanks......was that done for the extra injection event?
