Last year for Catalytic Converters? All 05 have cats?

[KaiHartman]

Just wondering if anyone had an 05 model truck that didn't come with a cat from the factory?



What was the first year that ALL trucks were equipped with a cat? Thanks!

04. 5 was a mid year change over. Anything from 04. 5 and newer has cats. Some previous CA motors had them also.

IIRC, on a 3 rd gen anything built after 1/1/03 required one, mine was built 8/02 and thus, did not come with one ! One plus for the thing I guess!

Yer off a year MMeier, cat-equipped trucks began rolling off the line Jan 1, 2004

As a bit of a history lesson all Dodge Cummins trucks came with cats starting 1/01/94 and ended 12/31/97 when the 24-valve came out. So except for the early '94s all 12-valves came with a cat. None of the VP-equipped 24v trucks came with a cat. Then the cats reappeared in the '04 model year.

Not sure about California in any of the above though.

Oh my, now thats fuuunny!!! :-laf:-laf



Yer kinda forgetting the 5 years previous to 94 when a CAT really was road kill, not something on your truck.





IIRC, only the Cali models 03-04. 5 required a CAT but there is something about the 1-1-03 that strikes a chord. Ah well, somebody here remembers the trivia.

 

[MMeier]

Hmmmm... . got to wonder, I pretty damn sure I knew of a couple of '03's ( non-cali) that had kittys under them, my exhaust guy used to save them!

 

[Pawpaw]

Vaughn has it right. Except for the California trucks, no Cat on 3rd Gens until the 04. 5s came out. That's one reason I wanted an early 04... no kitty or 3rd injection event.

Well I lost mine somewhere along the way but I am considering moving to an area where they do emissions testing. Any chance of me passing if I run the truck on stock programs?



I searched around the engine compartment for one of those "this vehicle came equipped with such and such emissions" and couldn't find one. As far as I can tell, unless the person doing the testing has access to dealer information and checks my VIN, or unless he or she is very knowledgeable about these trucks, they wouldn't be able to tell if the truck was supposed to have one or not.



Is there any way for them to tell??? Like I said. . hasn't been an issue before, but I may move into an area that does testing in a year or so. Thanks for the input!!

They do emission testing here also, in addition to the testing itself is a visual inspection. Last time I had mine done (May) I asked the tech when he was looking under the truck, what if I didn't have a muffler? He told me you pass without a muffler but no cat no pass.

Well mine was bulit Dec 03 and did not come with a CAT it has a Cummins:-laf

But how does each inspector know that the truck being inspected originally came with a catalytic converter??





If a fellow coworker is correct, trucks were sold in Texas without cats while emission testing was still mandatory in Grayson country (for example)...



Oo.

 

[CogginsP]

When I did emissions testing on my '97 it did not have a cat and I passed.

They look at the engine data tag on the valve cover it shows the cat spec number if it had one

 

[AKaiser]

I'm sure there's a database somewhere that tells them whether a diesel engine on a pickup had one or not, since, unlike gas engines, pickup diesel engines have only had cats in the last fifteen years. It's not exactly rocket science.

So what do they do when they encounter a truck like mine, where I have removed the plastic valve cover and engine data tag? I assume it is my right to do so, since no where on the valve cover does it state that it must remain with the vehicle by law... .

If you're so sure there's a database "somewhere", I'd surely like to know where it is kept. I went to watch some of the emission testing in progress this past month and only saw the gentlemen holding a clipboard. Pull in, get required info, inspect, test at exhaust, sign paper, new tag, and go. Doesn't sound like rocket science to me, but it doesn't sound like you're exactly on the right track either... ...

 

[nickleinonen]

i pealed off all the stickers off my valve cover when i painted it. . i actually am not sure where it is, but you can order a new sticker from cummins with your engine serial number [cummins quickserve can get you the part number for the sticker]

 

[klenger]

I suspect that removing or defacing the valve cover sticker IS against the law because it relates to EPA data. The fact that there is no warning would probably not be a good defence in court as I assume that there are no warnings on all of the other pollution control devices either.



Note that I am using words like "I suspect" and "I assume" and "probably" so as not to be accused of stating "fact" for what are my uninformed opinions.

If you're right I'm taking mine off tomorrow out of protest.

Well, if they go thru EPA certification requirements, the data exists at the very least at EPA Headquarters. Whether the test sites have the data or not doesn't mean the database doesn't exist. Logically, it can't NOT exist. I work for the Government. Databases exist for everything you could imagine, and some things that would baffle you.
