Engine/Transmission (1998.5 - 2002) Colorado emissions test

[mlockner]

Got my emissions test done today. What a rip, annual test on top of the plates. Gassers are every 2 yrs. Guess I do not understand the state of Colorado's thinking. Any way the truck passed fine. The guy said they see chipped trucks and stuff all the time and he has never seen one not pass. It is an opacity check that they perform under load on a dyno at 40, 50 and 60 mph is what the guy told me.

 

[ProspectorTim]

Opacity on my truck with rv275 injectors is lower than stock.

HP went up, from 186 stock to 230 with the new injectors.



Its no hot-rod, but is sure hauls my 5er better!

 

[James2000]

Hey Mlockner, did you say annual smog test? Should be every other year for diesels also. James

 

[ProspectorTim]

It's EVERY year here.

 

[James2000]

Every year in Falcon? I thought smog was a state run test? I'm In Boulder co. I've only had to get test every other year. James

 

[Joel Richards]

In Colorado, all diesel powered vehicles require a test every year performed by a licensed diesel testing station.



I'm not sure when the first test is due after buying a brand new diesel, but that might be good for 2 years. Maybe that's the confusion?



For more info, go to the Colorado Emissions website...

Mike,



Mine are due, and the emissions web site says bupkiss about diesels.



Where do I need to go, or who do I contact to set it up?

I moved to Colorado in Jul 02 and had the smoke test done. Was told by the owner of the dyno that my certificate was good for two years.



He must have been right, DMV accepted the certificate in Sep 03 when I registered my truck in the state of Colorado.



Ouch... registration fees are too expensive here. I got charged for commercial tags because my truck weighed over 6,500 pounds... crooks. Only paid $165. 00 in Alaska and my tags were good for two years.

 

[mlockner]

I have had my truck since July of 2000 and this is the second year in a row I have had to have emissions done and will annually after this as I understand. I know this is for the Denver area. The rules may be different outside the metropolitan area. When I get my renewal notices it states right on there that an emissions test is required.



Sticks, I went to a place on Sheridan in Arvada called the Emissions Clinic. They only test diesel trucks, but do repairs on gassers and diesels. It was 58 bucks for the test. There is a place down on Missippi in Denver also that I went to last year that was a little cheaper, but I was not impressed with their shop or people running the place.



Needless to say, if you set your truck up right you should have no problem passing the emissions test as they perform it and meeting the requirements. They say 35% on the opacity check and my highest reading was 15% with the comp on 1X1 as always (UNLESS I need to open up the WHOOP A$$).

Hello all, I am new here, but I have a 2001. 5 and when I got it used, it still had the emision exempt sticker on it. I have heard that it is only good for seven years. I cannont find any real info on this. Do any of you know about this? Thanks.

[mlockner]

Scott, that emissions exempt sticker is just decoration. There is no vehicle that is exempt for 7 years in the state of CO. Like I said when you get your renewal notice it will say if you need an emissions done before you get new stickers. Check out the web site that is posted in a previous reply.

One of the nice things about our new 3500 swd is that I can take it to a "regular" station. When we had the dually here in colorado, had to take it to a big truck testing facility and instead of the $35 for the exact same engine, we got to pay $85. Yes it is good for 2 years first, then after that every single year have to test in good ole Colorado.

FYI, straight from the website "Change of ownership requires a new passing emissions certificate supplied by the seller at the time of the sale. Tests are required for registration renewal when indicated on registration renewal card. Vehicles 1982 and newer will receive a test which is valid for 2 years. Vehicles 1981 and older will receive a test valid for 1 year. All diesel powered vehicles require a test every year performed by a licensed diesel testing station. "

Where do I need to go, or who do I contact to set it up?

Ok, now I am not a happy camper. Seams kinda dumb to put the exempt sticker on if it is not exempt. What is confusing me thou is when I had to go and get bent over for my tags, the card said no emission required. I am not found of how this state does the tags and testing. Sorry to rant but this is what I get for assuming. Thanks for the great info and the web site.

Thanks Mike L



Thanks Joel R

The gasser emissions testing places don't do diesel. However, they don't have a sign out front saying this. . . I was told after waiting in line behind four gassers, bout the last minute before closing time. Then they sent me somewhere, getting old don't remember where now, and they gave me a list of approved diesel emission testers that have state license. You can do all that. . . or just call Progressive Auto Performance and Diesel, Englewood, CO, 303-761-4232 and ask for an appointment. Most times for diesel test you need an appointment, takes about 15 minutes around $40 I think.



Cheers,

Golden Area Dyno

I go to:



Andersen's Foreign Car Service LTD, West Colfax next to Christopher Dodge. They give you the standard 40, 50 and 60 mph test. I don't know the type of dyno they are using and they can get duallys on the dyno as well.



I bought my '99 brand new at the end of 98. I've had to test every year since 2001.



time + test + plates = BS



I've also notice the test doesn't cost the same across the all the test sites, Whats up with that?! I thought they were controlled by the state.

Found this thread with a search, and thought I'd bring it to the top again. Just had to get my test done for the first time. Went to Exhaust Readers here in the Springs, and with the EZ unplugged, they measured a max of 31%, and the smallest reading was 29%. Seems awful high to me for a truck with just injectors. They did comment that the HP was rather high compared to what they normally see



Anyways, they use a superflow dyno, and they really pushed it hard (they don't let you in, but I could hear it). I'm thinking maybe it was their "technique" that resulted in the high readings. At least it passed, but am worried about next year. Any ideas (other than a TAG) that might reduce opacity?

 

[Rattlin_Ram]

Exhaust Readers wouldn't let you in??? They told me I could go stand in the door when they ran mine. WOW did it sound awesome, the 4" straight, in that bay on the dyno. I don't remember my exhaust numbers but I think the hp said like 187hp or something, that was stock with just the 4" exhaust. They expected it to be around 180.

In colorado, diesel emission testing facilities are licenced by the state, but remain independent, and are free to charge whatever they choose. This is different than the "Air Care Colorado" program, run I believe by Envirotest, which tests gas vehicles. They are specifically contracted by the state. Independent stations can not provide emsiions tests for gas vehicles since 1994 or so.



Also, as of present, emissions tests are required only in the metro counties... Denver, Arapahoe, Jefferson, Douglas, Larimer, Weld, El Paso and Adams, and vehicles that commute into the area.



Diesel vehicles are exempt for the first 2 years after new, and require yearly testing thereafter.



Anderson's is a good place, but they wouldn't take me after I got the stack. I use the place off of Mississippi and Santa Fe (roughly) In Denver.



Someone suggested the state website, good place for more info.
