How to Replace 2004 GMC ENVOY SPARK PLUGS

[@KevinNadeau]

Thanks for stopping by the channel, I hope this video is helpful. Let me know what spark plugs you use in the comments below. Check out my other videos linked in the description above.

Have same car had a knock then just stopped im thinking oil pump ? what do you think

[@KevinNadeau]

@@ronaldcordromp6056 That's a possibility. Check oil level and pressure. To check true pressure, you'll need to hook up a manual gauge.

The fifth cylinder spark plug where you would gap was completely gone I went with ACDelco plug 41-103 factory replacement still has misfire

[@victorhagan9833]

Great video. I checked getting a check service engine light on my vehicle. I took it to Advance Auto to diagnosis the problem. Initially, they got a P0300 error code. So I took it to a local repair shop and had them put it on their machine. They diagnosed a misfire on spare plug number 5. I was able to use your video to fix the problem. Which saved me a few hundred dollars.

[@KevinNadeau]

That's awesome! I'm glad the video helped 👍

[@josef.godina5199]

Pretty easy to follow directions. Thank you. Got it done on my 2005 GMC Envoy.

[@theallamericannightmare4163]

@jose F. Godina do you have a problem with the suspension on the front end of your Envoy. I have a 05 as well. And it has been nothing but a pain and money 💰 trap

[@josef.godina5199]

@@theallamericannightmare4163 just minor issues with it. But got that fixed. Hopefully yours isn't too bad.

[@donaldsousek9078]

New to your channel. I am an owner of a 2007 GMC Envoy. Between yourself and 1AAuto.com's channel, I feel more confident in tackling maintenance projects around my vehicle. I have tackled brakes, replacing a driver side window motor, and a few other things. Thank you for your posts. My next project on the Envoy is to get the back glass open/fix the button.

[@KevinNadeau]

Thank you! I'm flattered to be compared to 1A Auto's channel. The back glass button isn't that difficult. Let me know if you have any questions 👍

[@IsshmanGarcia]

Did this job last summer. Same year but a Trailblazer EXT. Job is pretty straight forward. Thanks for the video.

[@davidking8968]

I think its neat to be able to tool around on this vehicle to make improvements and when you do seems to improve fuel mileage and performance.

Best video I have seen on this procedure.

[@pontiacsrule8761]

I just bought a 2004 GMC Envoy. Thanks for this video. I was wondering where those spark plugs were. BTW you had low volume during the actual spark plug replacement. Very nice explanation of everything. I wish my engine bay was as clean as yours.

[@KevinNadeau]

Congrats on your new Envoy. I have a lot of other How-To videos on my channel related to this truck that you may find useful. And thanks for the info on my audio. I have since bought a new microphone for filming.

[@pontiacsrule8761]

@@KevinNadeau You can count on me to check them out. Hopefully you have one on the back hatch, GMC Envoy XUV. When you open the hatch from left to right it won't stay in the open position. I will check out your over videos, thanks again.

[@crystalprice4819]

@KevinNadeau I've got the coils off and none of the spark plugs will budge, and I'm afraid if I push to hard I'll break it in there.

[@crystalprice4819]

How do I get the spark plugs out without breaking if they are stuck in there

[@KevinNadeau]

@@crystalprice4819 Sorry, I haven't run into that issue yet. Do a search on YT and see if anyone can offer some ideas. I'd be interested to know how it works out for you. P.S. I might would try spraying a little penetrating oil in the plugs wells and let it soak for a while.

[@Wendy-il3lu]

Should you wait for a thrown code to change them? Mine is having poor acceleration but I also dont want try to fix something that isnt broken yet.

[@KevinNadeau]

You should change them according to the manufacturer’s recommended intervals

[@jimlodwig]

Kevin great video. Appreciate the tool list, keeping the cam steady using a tripod and like the green book.. excellent idea! I've a 2006 chevy trailblazer I bought from a friend 7 months ago that now has just over 175k. He had regular service and work done since I've known him and was the original owner. Unfortunately since I picked it up I'm having check engine lights for multiple reasons since I've had it. I'm starting to wonder if the place he's used for 5 years did much actual fixing. Maybe it's just luck of the draw. Fortunately because of videos like yours and a few others I've been able to do what luckily are somewhat easy fixes. I'm far from a mechanic but at least I can still do some basic work on the trailblazer. Glad I found your videos.. so many the guys are shaky and don't give good details. I'll subscribe.

[@KevinNadeau]

Thanks for the support Jim! I'm sure you'll have many good years ahead with your Trailblazer. Let me know if there is anything I can answer for you. As far as the check engine light, I'd suggest investing in an inexpensive OBD2 scan tool like this one amzn.to/37rtmiz (and go ahead and pay for the premium version of the Torq Pro app, well worth it IMO).

[@jimlodwig]

@@KevinNadeau Already have an obd. it helped me diagnose the code for the work I needed to do. was getting p0014. I changed the camshaft sensor first. Check engine still came on so moved to the vvt solenoid which corrected the issue. Saved enough on repairs it justifies upgrading to the pro version of torque :-)

[@KevinNadeau]

You're welcome! You might need to replace the valve cover gaskets. There are gaskets around each of the plug wells. Good luck with your truck.

Question, Why didn't you change the coils when you changed the plugs?

[@KevinNadeau]

Because they worked just fine. No misfires were detected.

[@rickcoloh9083]

@@KevinNadeau I have a 2008, mine seems to be missing so not sure if just plugs will solve it but its the first thing to try. I have the coils as well but figure if I put them both in I won't know which was needed. The coils are kind of odd as well price wise. I bought mine off Amazon and some that were listed would cost as much as much as a whole set. Any thoughts?

[@Thesaurcery4U2C]

No issue on #6 plug? I may have missed it in video. 🧐

[@KevinNadeau]

It’s a little tight, but I had no problem with no. 6

[@Thesaurcery4U2C]

@@KevinNadeau HEY.... Thanks for the reply. I'm having a known misfire issue on #6 and have heard it could be tough getting it out. On the TB's and envoys the gasket that seals the hood against rain, gets pinched, or maybe cut?, but it fails, and a little water over time will puddle around coil area, or into plug cavity. Just an FYI in case you hadn't head about that. When I seen #6 wasn't filmed on your vid, I thought maybe the people crying wolf were correct about this one. I had even read about, rigging up (ruining. lol) a tool to get in there? Now I'm wondering if anything about the envoy or TB-(mine) are different in the firewall form, or I have just previously stumbled across several "vice grip mechanics" Never the less Good video, with clear instructions. I've only used a shop a couple times in my life (54) and that was on things I would just rather pay, because of the hassle of doing them, so this really isn't anything, as I have owned some junk when I was younger, and also built Bottom up, top down and dropped a 427 in a 87 Buick regal that never lost in a town of 40k. (senior year HS) For a few years now, I take some time and look through videos, before I do anything really, and see what issues may arise, grab a fist full of exact socket sizes, etc. But the little techniques you find people do is where the GOLD Is (IMO). Last month I swapped transmissions on my daughters car. After watching a video, you can see that the tail end has to go up quite a bit, once it is separated, and low enough to allow that torque converter to possibly slide off. 9/16 angled box end wrench held to bell housing, along with original bolt + washer, with angle leaning wrench towards converter tight. These little; !OF COURSE! findings are great. I'll come back and give you a sub, and check out some more of your videos. Thanks again for your reply. Man I get text chatty when talking about anything with engines or legs. Lol. Not knowing your audience, throw me a peace sigh if you would like me to edit that last analogy. He.. he. np.

That is a good point. My service manual calls for a plug gap of 0.05 inches with AC 41-965 plugs. However, the new plugs (AC 41-103) come gapped from the factory at 0.04 or 0.043 and you shouldn't need to regap them.
