I’m working on my 2003 trailblazer today. And using this part to save me a lot of money. Thank you for the tape measures trick. That makes things much easier.
Great Video I am a issue with my 2004 Chevy Envoy XUV.. This guided me through the process of where the leaks could possibly be and how to fix them. This is informative as I take the Vehicle to the Shop for repairs I have some idea of what could be the issues and how it could be repaired, I can understand the Shoptalk language of parts and repairs regarding this issue…
It's certainly possible. There are a large number of EVAP tubings and the vapor canister and the EVAP vent valve (on the tank) and the EVAP purge valve (on the intake manifold on the 2003/2004 5.3L engine). You may need to get a smoke test of the EVAP system to help pinpoint the location more easily.
I would believe that you would have one ore more DTCs set mentioning a small or large EVAP leak. I don't know where you're located, but most automotive repair shops will have the a smoke test machine. They may charge you for one hour of diagnostic time to investigate the issue to see if they can locate the leak. If there is more than one DTC present for the EVAP problem it too may help narrow down the source of where the PCM/ECM believes the leak has impacted the EVAP system (not necessarily the leak but the things it may be impacting which might help narrow it down).
RetroCarGuy530, I forgot you would not recognize me by the yt name. Lol. This is Dani, I have Annie’s 06 FPR 6spd silver with the blue flames here in Sacramento/Roseville area.
Since you're somewhat local to me, I could attempt to check out your SSR's issues. I have a smoke machine and a decent scan tool to check for DTCs. I don't have an auto repair license, but if you're ok with that, I can attempt to check out your SSR's issues.
This is awesome. I bought the part a few years ago but due to living in an apartment complex, I haven't been able to put it in yet. Too big of a job to not the get attention of the apartment management nazis. I have an 03 Envoy XL 5.3
I don’t know if you noticed or my manual has a typo but the instructions say at the very end (step 13) that the black gasket goes on the outside of the tank. Which makes no sense nor can you see the black gasket in their instructions or video.
That's why I called Dorman to confirm where the gasket should go. It should go on the inside of the tank and the nylon washer on the outside of the tank.
The GM special coverage document 14423C only lists the follow vehicles that will have the problem. 2004 Buick Rainier 2003-2004 Chevrolet SSR 2002-2004 Chevrolet TrailBlazer, TrailBlazer EXT 2002-2004 GMC Envoy, Envoy XL 2004 GMC Envoy XUV 2002-2004 Oldsmobile Bravada The Dorman Products website for the replacement inlet check valve list the part fits: 2003-2004 Chevrolet SSR, 2002-2004 Chevrolet Trailblazer Base, 2004 Chevrolet Trailblazer SS (but this didn't exist in 2004?) The GM part number for a fuel tank used in a 2007 Trailblazer appears to be 25973153 and that's not one of the fuel tank part numbers listed in the 14423C document. Part Number Description 15077622 Tank, Fuel (18.7 gal.) 15229311 Tank, Fuel (21 gal. w/o filter) 15231628 Tank, Fuel (21 gal. w /filter) 15229310 Tank, Fuel (Ext Wheelbase/SSR) I cannot tell if the inlet check valve in the GM fuel tank for the 2007 Trailblazer is the same size / type as the earlier model years where this problem was documented. Based on that info, I'm guessing that this solution will not work for the 2007 Trailblazer.
where did you find that plug for the tank ? also, if I go this far and my fuel pump has never been replaced should I replace it ?, I'm guessing you have a video on fuel tank removal ? thanks for all your help
The Dorman inlet check valve can be purchased on Amazon. amzn.to/43ekGJ3 If you're taking the fuel tank down to install this check valve, it may be worthwhile to replace the fuel pump if it has a high number of miles on it. I have a video showing the fuel pump replacement on a 2004 SSR. 2003-2004 Chevy SSR - Replace Fuel Pump: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iddHk1IXTi4.html
@@RetroCarGuy530 Thanks , I ordered the Dorman inlet check value , I was talking about that plug you used to keep the trash out while you were cleaning
That is a swimming pool #9 return line winterizing plug. You can buy them in a lot of places, but I purchased mine from Amazon. Here's the link to the one I used in the video. Swimming Pool Return Line No. 9 Winterizing Plug 1.5 - 1.75 Inch: amzn.to/3ITna7u
If this repair only covers up to 04, what can be done for the same issues on an 05 TB? What sealant is gas resistant so i can just bandaid it for awhile?🙏🏼
I don't know of a similar solution for the later model year gas tanks. I've never tried to seal a fuel tank with a gas resistant sealant. I usually use J-B Weld products when I attempt to seal/fix something requiring epoxy. I see that J-B Weld does have an 8217 TankWeld product, but I've never tried it myself. I wish I had a better answer for you.
Does this cause a p0442 code for small evap leak with you have this bad roll over valve? On the 03 Trailblazers theres a recall for the fuel tank and the dealerships fix is to replace the entire fuel tank. A smoke test has to be done through the fuel tank so see it, i think. Everything else was checked tested and replaced for the evap system. Theres other people that talk about this valve causing the small evap leak code and then you cant pass a smog.
The plastic inlet check valve for the fuel tank can develop small cracks which can of course result in an EVAP related leak code like P0442 and potentially leak gasoline. A service tech that is good at performing smoke tests, should be able to see smoke escape around the base of the inlet valve at the fuel tank. Although, a very small leak might be somewhat of challenge to see during the smoke test. When you stated there's a recall for this on the 03 Trailblazer, I'd like to make a clarification to that statement. A recall by an auto manufacturer is something they must fix for free, usually without restrictions. GM issued a "Special Coverage Adjustment" (not a recall) document with an id of 14423C. "14423C - Special Coverage Adjustment - Fuel Tank Inlet Check Valve Fracture" The 14423C special coverage adjustment would cover the repair of this inlet check valve fracture which results in a fuel leak for a period of up to 15 years from the vehicle's in-service date or 150,000 miles. The Dorman replacement inlet check valve used in this video is one possible solution to the problem, especially since no vehicle covered by 14423C would be covered any longer due to all of them being in service for more than 15 years. A P0442 can be caused by so many things in the EVAP system including the inlet check valve fracture/leak, tubing that is cracked, o-ring seals that are cut or have deteriorated, a leak around the fuel pump because the lock ring may have rusted thus allowing the fuel pump seal not to seal properly (areas that use road salt in winter). EVAP leak codes can be some of the nastiest things to track down. It requires a service tech with good diagnostic skills to work the problem to find the actual root cause.
If it were spillage from the pump the hose/tubing running from the gas cap area to the tank would show signs of "wetness". If it's the tank only, you'll see it around the inlet check valve.
Dorman lists this as fitting "Chevrolet SSR 2004-03, Chevrolet Trailblazer EXT 2004-02, GMC Envoy XL 2004-02, GMC Envoy XUV 2004". Those are all the longer frame versions of those makes/models. The Chevy SSR is based on the Chevrolet Trailblazer EXT which is why it works for 2003/2004 Chevy SSR.
Here are the specifications from the Dorman website for the product used in this video: Thread Outside Diameter: 39.4 mm Hose Mating Diameter: 36.1 mm Inside Diameter: 25.75 mm Length: 168.5 mm Material: Aluminum Package Contents: Inlet Valve; 2 Washers; Gasket; Threaded Fastener; Installation Wire Package Quantity: 1 Packaging Type: Box Selling Package Quantity UOM: Piece
Here's a list of vehicle's the Dorman 577-106 part fits directly from the Dorman website: 2004 Chevrolet SSR 2004 Chevrolet Trailblazer EXT 2004 GMC Envoy XL 2004 GMC Envoy XUV 2003 Chevrolet SSR 2003 Chevrolet Trailblazer EXT 2003 GMC Envoy XL 2002 Chevrolet Trailblazer EXT 2002 GMC Envoy XL
If your GMC Envoy is a 2002-2004 model year, it may fit your vehicle. Dorman Products lists the following year/make/model info on their website for this product: 2002 GMC Envoy XL 2003 GMC Envoy XL 2004 GMC Envoy XL 2004 GMC Envoy XUV GM/Chevrolet would not cover any of the expenses to replace the tank in my 2004 Chevy SSR because it was more than 15 year since its in service date. If the "14423C special coverage adjustment" document was applicable to your GMC Envoy, then most likely the Dorman Products replacement inlet check valve part will fit. You can call Dorman Products 1-800-523-2492 and verify if this product will work with your vehicle.
It looks like the 2003-2004 Isuzu Ascender might suffer the from the same issue. It looks like Isuzu issued a special policy adjustment document. Here's a link to the PDF document for that issue on the NHTSA website. static.nhtsa.gov/odi/tsbs/2016/SB-10083912-0335.pdf I don't know if the 2006 model year Ascender has the same tank. You could call Dorman Products at 1-800-523-2492 to see if their product would fit the 2006 model year Ascender. The Dorman Products website does not list the Isuzu Ascender at all in their website info for this product.
@@RetroCarGuy530 I called Dorman and they said they don’t have or know anything for the 06 unfortunately. I need to find out why the pumps at the station don’t let me fill up at a normal pace. It always triggers it off
Whatever sealant would need to be resistant to gasoline and it would need to be embedded deeply into the area where the inlet check valve attaches to the tank body. Which likely means fully breaking off the inlet check valve since many of the leaks for this item a hairline fractures. I'd rather use the replacement inlet check valve with its gasket and mechanical method of securing it rather than hoping I was able to get enough adhesive/sealant to fully fix the leak.
I don't know if the Dorman part will work on the S10. The vehicles involved in the "14423C - Special Coverage Adjustment - Fuel Tank Inlet Check Valve Fracture" are: 2004 Buick Rainier 2003-2004 Chevrolet SSR 2002-2004 Chevrolet TrailBlazer, TrailBlazer EXT 2002-2004 GMC Envoy, Envoy XL 2004 GMC Envoy XUV 2002-2004 Oldsmobile Bravada I would suggest calling Dorman to see if this part would fit the 2003 S10.
Dorman lists this part as only working for extended models this makes no sense to me it seems like it would work for any of them short base or extended. Do you have any experience with this Dorman part working in a standard wheelbase trailblazer?
The shorter wheel base Chevy Trailblazer / GMC Envoy likely used a smaller gas tank. It depends on location and type of inlet check valve used in the tank. I cannot find anything that proves the EXT's fuel tank inlet check valve is the same as the short wheel base version. The Chevy SSR (my vehicle in the video) is based on the Chevy Trailblazer EXT which has the same 25 gallon gas tank as the Chevy Trailblazer EXT. I'm sorry that I cannot be more helpful.
There are only 2 size tanks for the for the base and extended, either can have either tank (if you have the sticker in the glove box you can see which you have) 18.7 or 22 gl. A friend that has a shop said that the doorman valve works on both tanks, I have known him for a while and he is usually right, have a standard wheel base and the 577-106 on the way. So I will know in a couple of days. The size difference of the tanks is not much and I cant imagine it would be a different neck for 5 gallons.
Just got done talking to GM assistance in financial repairs on the gas tank on some of these GM cars they're doing everything they can to avoid this being a recall somebody needs to sue their asses off I have 03 Chevy trailblazer it needs to be recalled the gas tank is faulty leaks gas $260 just to go have an inspected by a dealership then they'll help you somebody needs to sock it to them and give them what they deserve like I said my car is a '03 I'm pretty sure somebody out there has lost their life
IMO, GM should have at least included a free inspection of the customer's vehicle when they first issued the special coverage adjustment document for this issue. Other manufacturers have had issues where they had the customer bring in the vehicle to inspect the vehicle for a specific condition and if necessary fix it. Not a recall, but at least they would try and proactively address the issue if the problem is present. I contacted the service manager I work with a lot at a local Chevy dealership and I had her submit a request for this issue to be covered to some degree (good will) under this special coverage adjustment and GM's response was no, but they would reduce the price of the fuel tank to some degree. That still made it a $1400 or so repair, so that's why I addressed the issue myself. I was lucky that the leak was a very small leak in my Chevy SSR's fuel tank. This particular problem tends to start off as a very small leak and only gets worse if the fuel tank inlet check value connector is exposed to some amount of stress.
@@Thumper68 it's a major gas leak think about it if hitting the tracks is enough to crack the spout nozzle a lot of gas is going to come out poor construction poor material thanks gm we're just going to start buying China's cars
Jim wants a thousand dollars for '03 Chevy trailblazer gas tank you know you can't get one at the junkyard cuz it's going to do the same thing the original one did they're giving us no choice but to use a design as somebody else designed to fix their mistake they need to take responsibility $260 for inspection and a dealership just so they can help you with repairs for a gas tank that cost $1,000 who's the crooks
The full list price is $1000 for the tank, but you can find it for roughly $670 plus shipping on many online GM parts retailers. That's not cheap, but better than $1000 list price. I wasn't happy either with that pricing. That's why I opted for the solution I used in this video.
100+ bucks for a check valve that’s absolutely unnecessary and does nothing. Don’t flip your car and if you do the tank is in the rear and not near anything that hot really I would just repair this with stuff I have at home if necessary lol
If you can repair the EVAP leak caused by the cracked plastic inlet check valve, great! The point of the repair is to fix the EVAP leak and potential fuel leak in a reliable manner. Since it involves the area of the check valve, this is a far more cost effective repair than GM will recommend which is replacing the entire fuel tank at a cost of over $1100 USD.
