2009 GMC Acadia spark plug replacement

WARNING: I incorrectly state cylinder order in the video. It is actually:
1 3 5 (against firewall)
2 4 6 (front)
2009 GMC Acadia SLT spark plug replacement including intake manifold removal. Accomplished due to intermittent stumbling RPM at idle which dealer troubleshot to a faulty spark plug.

[@brentchambers3820]

Thank you very much for this video. Just finished the job, replaced all 6 plugs and ignition coil packs. Saved a ton of money over what dealership wanted. Plugs came out looking horrible after 86,000 miles, and each plug was gapped at about .053. She runs smooth now!

[@douglasgriffin1385]

Thank you for your video. Watching your video helped me complete the same task. I have a code P0304 which was cylinder 4 misfire. My only improve is that after searching for how the cylinders are numbered, the correct numbering is from left to right 1, 3, 5 in the back (closest to firewall) and 2, 4, and 6 closest to bumper. Again, great video. Thanks, Doug

[@davidjsouth231]

I did my daughter’s went pretty well. Took about 2 hours from set up to clean up.

[@andrewyanoschak9948]

Great video! It gave me confidence that I can tackle the job. I have a 2009 Enclave with 103k miles. I was planning to change the plugs out since the car has over 100k mi. A couple days before I planned to do the work, I got code P0301 - Misfire cyl 1. I could definitely feel a problem, especially while accelerating. I wasn't sure if it was a spark plug or coil issue. I changed out the plugs and while I had it apart, swapped coil packs 1 and 2. After start up, I got code P0302 - Misfire cyl 2. Sounds like a bad coil. I ordered 6 OEM coil packs from RockAuto and that solved the misfire problem. I went ahead and changed all the coils out so I don't have to deal with this problem on the other cylinders in the near future. The job was very simple the second time around. Side note: I originally ordered the plugs specified in the owners manual: AC 41-107 Iridium Plugs. The plugs actually in the car were AC 41-990 Platinum Plugs. I purchased a new set of the original AC Platinum Plugs since they performed well and still looked good after so many miles.

[@Nicevideos4u]

Thanks a million for this video. I'll will tackle this project this coming weekend. I have an 09 saturn outlook. Same engine. It started to misfire and diagnostics said it was 2 and 4. I have purchased all 6 coils to replace and also the spark plugs along with a new gasket. Several mechanics prices ranged from 300 to 375 just to replace coils and plugs (just for labor) I bought the above parts for 200. My local auto parts store wanted 70 for each coil. I purchased them all for 100 online. I guess a tune up gets expensive these days. Anyhow, I will attempt this project tomorrow following your video. Thank you so much again for taking the time.

[@TexTornado522]

Thank you for this detailed informative video. I had the same problem with my 2010 traverse 78k miles. At first The task looks too big for a non mechanic But after watching your video it didn't seem hard at all. I changed the plugs with no problem. And the problem is fixed. My bank account thanks you for saving me several hundred.

[@overthehandlebars]

I have a 2013 Traverse. I wont need to do this for a while but after watching this great video I am confident I can handle the job myself

[@warrengee8518]

Just performed this on my 09 Acadia as well. I also changed the lower intake gasket as in the video. Plugs looked really bad as I was at 106k miles on them.Wasn't as hard as I thought it would be & everything is running smoother now. I might add that I went with NGK spark plugs as i've had really good luck with them in other vehicles.Thank you so much sir!

[@tntvacationtravel]

I have a 2012 and it has started to do the same thing at idle and even during driving now. It has 155k miles. Thanks for the great step by step instructions. I'll be taking this job on very soon.

[@dewaynegraves2374]

Spot on with the video!! And excellent breakdown on the intake! Seemed impossible until I watched your video!! THANK YOU !!!

[@cullensmith8613]

Great video. Here is a note for people in my situation. With regards to my issue of just having a misfire code on cylinders 3 and 6. On my 2009 Acadia I was able to remove the #6 coil pack without having to remove the intake manifold; I did have to unbolt the throttle body. The same is true for the rear (firewall side) coil packs 1,3,5. It looks like coil packs 2 and 4 are the reason the manifold needs to come off, to change those plugs.

[@FearlessMods]

Thanks for the additional info. Between you and +Jason Keeley straightening me out on the correct cylinder numbering scheme, I think anyone watching this and reviewing the comments has all the info they need to determine how deep they need to go and how to do the full job if they're replacing the plugs or any of the stubborn coils.

[@jaywebb0113]

i am drive ability tech for gm... gmc/buick dealership. the gm plugs come pregapped . you are using aftermarket plugs in your acadia . in my experience that motor does not like after market plugs or coils. just had to change coils and plugs on a 10 acadia thursday due to a misfire underload at highway speed and the owner claimed they did the plugs. found after market plugs n coils . replaced them with GM parts... problem went away...

[@ryanbrunson777]

Thanks a million for this video. You're the only person on the net that I could find with helpful info on doing this. I'm a small block chevy guy so when I saw the engine on my mom's car I was baffled when I couldn't find the plugs. I also would have never thought to pull the entire intake off to change them. It was way easier than it looked but I couldn't have done it without this vid.

[@FearlessMods]

Ryan, I can totally relate! Glad it helped...I was also shocked that there was nothing else out there on how to DIY!

[@kirbypatrick8779]

Thanks for the advice. I have 165k on my 2013 traverse and still runs smooth. I know I’m way overdue though!!

[@TheOnePav]

Alright, I tried this before watching the video. Pretty much the same except you don't need to disconnect the side tube to the air inlet, not remove the heat fiberglass shield on top of intake manifold, and the plug connectors are more easily ans safely removed by pressing on the lock tabs while sliding a flat screwdriver on the other. Additionally, I would not recommend removing all 6 plugs first, but exchange one at a time. It was indeed hard work!

[@sierra6760]

Great job on video, I worked on my 09 Acadia yesterday, changed coil packs & spark plugs very easy job.

[@AnthonyJames1983]

+Dave SiErRa I hope you didn't change your ignition coils as a maintenance precaution. LoL!! Only replace them if they are faulty. Plus, they are expensive ;-)

[@JamesChavez-tc2gh]

The video is so clear and step by step that even encourage me to do the work myself. thanks again

[@brianlopez2045]

I have a 2009 Saturn Outlook, same exact engine though, and I too have had a stumbling problem with the engine. The check engine light did come on for me and when I had it check it stated that had a misfire in one of the cylinders, can't remember which one exactly, but found your video and it is exactly what my car is doing. It was very helpful in figuring out how to get to the plugs, I wasn't sure I'd be able to do it because no where else out there shows how the home mechanic can do this. They want you to have everything serviced by a dealer and spend tons of money. So this was very helpful and thanks for posting it. I just figured that I would go ahead and replace all the plugs and see if that would correct the problem.

[@FearlessMods]

Hope it takes care of your stumbling problem!

[@Nicevideos4u]

Did it take care of the misfire? I have an 09 saturn outlook and my check engine light came on as well and a misfire was diagnosed and you can hear the misfire quite strong. Fixing to the same project and wondering if it took care of your problem.

[@jonathanthomason1692]

Didn't mean to hijack your video. Actually I found your video so I could see how to remove and replace the manifold myself. I decided to make the attempt without removing the manifold after watching your vid. I'll post a follow up video when I get the car back from the mechanic. It's in the shop for a continuing check engine light problem, possibly a bad timing chain, cam issue!! I will update soon. Jon

[@MrIndyMike]

Thanks for the Video, it helped me save about $300 in labor, it took a while (Saturday afternoon nap midway through the tear down) but I got it all back together by watching your video-Cheers!

[@dennislis4207]

I have a 2012 GMC Acadia with 114,000 miles on it and I did not have to remove the intake at all to change the spark plugs. I had no issues removing the coil packs and the spark plugs. The whole job took about 1 hour. The only thing I had to remove was the purge valve solenoid above the number 6 cylinder (far right front of engine) to get to the coil pack and spark plug. I used the spark plug lubricant and AC Delco iridium plugs. I hope this information helps anyone with a 2012 Acadia, Traverse, or Enclave, it was not much trouble at all to change the spark plugs.

[@FearlessMods]

+Dennis Lis Thanks...I wonder if there was a slight redesign between the 2009 and 2012 engines?

[@dennislis4207]

+ctcrhenderson I believe there was, because after watching the above video I was not sure I would attempt to go through all that just to change the spark plugs. I took the cover off the engine and realized that my engine intake was not in the way at all. Since this is about the only video on this vehicle, I wanted others like myself who wanted to do the work know that it was a lot easier on a 2012 model. Dennis

[@ZGDX_Smiling_]

@@FearlessMods Yes the 2009 to 2011 has an Aluminum Intake Manifold without MAP Sensor. Mid 2012 to 2022 they all have Plastic Intake Manifold with MAP sensor on top of them now.

[@ZGDX_Smiling_]

@@dennislis4207 Now there are a lot of videos when I looked back on it. The aluminum intake manifold would be covering the front rear engine ignition coils. The back front of engine ignition coils would be easy to get to from on top of the engine doing the reach around.

[@brianlamendola6580]

According to the 100 dollar diagnostic... I was having misfires also.. my rpms were bouncing with motor hesitation similar to this video.. also was getting an engine light and a low oil pressure alert that WASN'T showing up in the diagnostic. Oil levels were fine. My rpm range was at 4000.... after replacement of the plugs the rpm range went up two tics...also similar to this video the gap ranges on the plugs I pulled out were all over the place. No apparent bouncing or motor hesitation any more. Will update this post if the engine light comes back on or other warnings. P.S. they wanted 300 dollars to do this maintenance level of engine work. Thanks to this video , with the rebate I got on the plugs, cleaned and reused the manifold gasket it cost me 30 dollars and my time.... God I love google mechanics!!!! LOL

[@Gawenit]

Did you have anymore problems?

[@rhouseautomotive]

Awesome video. Thank you. We are experiencing this problem right now, so I'll be doing this job this afternoon.

[@senorialequizio7688]

Note to self search you tube before buying car. Just got a Chevy Traverse, having bad case of buyers remorse. Great video!

[@michael6165]

I own 2009 Saturn Outlook XR approaching 100K plug tune up. Thank you for providing wonderful how to video. Now I will tackle that weekend project with enough confidence. Thank You.

[@frankbama3684]

Good video but as explained elsewhere 2, 4, and 6 are at the front. 1, 3 ,and 5 are against the firewall. I was about to make a big mistake until someone straightened me out as I had misfires on 4 and 6. I actually thought I had transmission issues since I didn't have any codes. Stuttering on upgrades will give similar symptoms. The good thing is I didn't have to remove the intake to change the number 4 and 6 coils. I did remove a connector bracket that helped me wiggle out number 6 and I removed the vacuum hose nipple right above number 4. You can see this nipple in the video. The only issue I had was that the coil boot separated from the coil when I pulled number 4 out. It was stuck on the spark plug and I had to dig it out with a 90 degree scribe.

[@AnthonyJames1983]

Thanks for this vid. I own an '08 and it's about time for my plugs to be changed. I too have been experiencing the idle time dipping. I cleaned my MAF sensor, adjusted it, and replaced filter thinking it was an air/fuel ratio issue as idle is high at times. I have no codes either, so spark has GOT to be what the next step is. Cheers!! Thanks again for the share ;-)

[@kevinyarbrough3858]

One of the best how to videos I have ever seen... Thanks for posting

[@johnferrara5249]

Did this last night, great instructions. It was a little tricky getting the intake manifold back on straight, other than that, easy job. Thanks!

[@lawerncebliss7820]

You do not need to pull the intake. You can get to the plugs from the back, just gotta be careful.

[@kristopherhasenbuhler5393]

Im about to try it without pulling the intake

[@chrisdinges5515]

The early models you need to pull the intake, they changed the design. At 4:55 he shows how the coil pack is locked in by the overhanging intake manifold

[@jonathanthomason1692]

You can take the engine cover off the top and access a small area to the left where you can reach in behind the intake. I have small arms and could reach all the way to the back plug. Remove the coil with a 1/4" ratchet to get to the plug. I then used a plug socket and several short extensions and added them to the socket under the cowling. Harbor freight has locking extensions that make it much easier. Hope this helps.

[@FearlessMods]

Mr. Thomason, thanks for sharing. When I did mine, I recall that I couldn't get the coil and plug boot to come out of the tube (it would hit the intake manifold before it cleared the hole). If the coil and boot come apart, then it may be possible the way you described. However, given how easy it is to remove the intake and give yourself total access to do the job looking straight on regardless how big your arms are, I would still do it the way I did. Thanks for the good information.

[@crustnq]

Thanks for the video. I was having an engine stutter at low RPM freeway speeds. 2009 Outlook. Engine code stated a misfire on Cly.2. I replaced all the plugs and the coil pack on cyl 2 today and everything seems to be ok after first test drive. Had a small scare...when I first started the car after the repair, it was idling really rough. Turned it off and started again, and it was fine. Not sure I would have attempted it without watching this. Thank you

[@jonnycattt]

Thanks a lot for this! It was just what I needed. The job did seem daunting, but with much help from your video ended up being fairly straightforward.

[@ralphpanarello8054]

This video was GREAT!!! One of the best on KZbin... You helped me so much - thank you. Just finished my car - 2 hours...

[@JosephVincentandsons]

Great video. I'm experiencing this hesitation in our 2012 Acadia and was hoping new plugs would be the answer.

[@timparrott2552]

Think a good added thing would be to give the amount of time it takes to do any job . That's so person doing repairs can set a time line and know how much time is needed for the job.

[@jessicatabor341]

Approximately 4 hours minimum

[@falahkhachan9409]

Thank you for posting this video because you are helping a lot of people that have the same car like me.

[@patsfan1150]

Good video, just a few comments. 1. i would replace the intake manifold gasket, never reuse a gasket. 2. always use OEM spark plugs, never cheap out on ignition parts. 3. you said tighten the manifold bolts in a circular pattern, should be criss cross. Also you should just do one plug at a time.

[@ralphl5441]

With a distributor I do agree with your comment to change only one plug at a time. This does not apply to a COP.

[@PsychoFisho]

criss cross starting at the center, then work your way to the corners

[@wadephillips5575]

Thanks for posting. Great walk through. Made changing the coils and plugs on my wife's Buick Enclave easy. Autozone sells a nice magnetic spark plug combination swivel and extension that worked very well for the deep wells.

[@eddyvasquez7215]

Thank you very much, I have the same vehicle as you and have that same problem with the hesitation and I can see it on my rpm Gage, so I'm going to fix it my self after watching the video man it's no sweat, easier than changing a head light on this damn gmc Acadia lol

[@cessarflom8664]

EmilyTV - ill doit for you baby!

[@krisanderson1031]

Actually it's not that hard at all. I had a 305 code for misfire on cylinder 5. As I started to pull hoses I saw that I could actually see the coil pack I needed to remove. Left all hoses attached and removed the pack. Swapped it to a different cylinder and the code 305 changed to a 303, yay! The code moved, bad coil pack. Did this at 1:30 AM! Had to baby my way home and it took me an extra hour to get home. Anyway, once the code moved, put it all back together then went to the parts store this morning and got a replacement pack. Replaced it in about 5 minutes. I didn't need to pull the cover off like the video shows. I'm sure that the front ones might need the cover removed.

[@TheMDBandit]

I'm so glad I found this video . I have an idea of what what kind of monster I'm going to face pretty soon

[@davesherman74]

Good video! I have a Traverse which is due for a spark plug change. Got a little spooked by the notion of removing the intake manifold, but that looks much easier than I thought.

[@carloseta9049]

If I attempt this do you think I will be able to access the O2 sensor on the manifold to replace it? Mine is bad. Thanks for the great video!

[@FearlessMods]

Carlo Seta I haven't had the Acadia for a few years now so unfortunately I can't check it out for you. Good luck.

[@kartboarder22g17]

I'm guessing when they put some coolant in the motor they spilt some and it landed by your intake manifold and burnt up and evaporated, other than that I'm at a loss for what it could be.

[@robertlarkin4420]

I have a 09 SLT with almost identical miles. My miss or stumble is at around 65 mph though. I've had three coils replaced and it always comes back. I wonder if spark plugs are the problem. I will replace them and see if it helps. Thanks for the video.

[@LurkenLarkin]

ctcrhenderson Thanks for the reply, I changed the plugs yesterday. Only hiccup I had was that I did not have an extension long enough to reach spark plugs. After I acquired the extension it went great. Time will tell if it goes away, we haven't driven it a decent distance yet. It usually happens while in cruise control uphill around 65. Also noticed a small stumble at idle. Im thinking the plugs not being gapped correctly from the factory could be the main cause of everyones problems. If true, GMC really dropped the ball on such a minor detail. All the plugs I removed were gaped at around 51. The video helped ALOT, thanks again!!!

[@davemahoney6725]

Bobby Larkin did That work? mine is doing the same thing (09 SLT) and the dealership said it was the 6th cylinder and it is the ignition coil. and of course they want to charge me 720.00 to replace it.

[@LurkenLarkin]

[@portmasterip]

We have a 2012 GMC Acadia SLT with 58k miles and it does the same exact thing. It has started doing it bad enough that it tries to surge forward at stops. The RPMs drop then it recovers. Dealer does not know what is causing it. I am going to replace the plugs. Thanks for the video! :)

[@FearlessMods]

Hope it takes care of your problem...yours sounds dangerous!

[@evanstanek5838]

Changed plugs on my Toyota in 15 minutes, and I'm not a car guy. Now having a larger family and an Outlook (same thing as this) everything on this vehicle is just badly laid out, is anything easy to replace?

[@DestinyPlayerTitanClass]

After figuring out that my 08 Acadia had starting issues at the gas station, I researched and found that a new purge valve would fix it. Well...my last trip to gas station I heard a pop (haven't received the part yet) and now...I have idle issues. Figured it'd be the spark plugs since it's intermittent and only at slower speeds but still feel the shake at regular speeds. I took a look to see where my time will be spent and those plugs were alien to me; thanks for the video...it will be my guide when I change both parts out. Not exactly certain where the purge valve is but it appears its behind the air housing assembly; do you have to remove the manifold to change out the spark plugs?

[@jhitt79]

The reason you had different gaps on the old plugs is because they are worn. The way I start new plugs in the threads is using a 8"-10" piece of 5/16 hose. Slip hose on plug, insert plug into well via hose, hand thread by spinning hose, pull hose off plug and finish with (torque) wrench. This is an old mechanic trick that I think works better than anything for starting "coil on plug" spark plugs.

[@sanjose5090]

Thanks to KZbin, I changed all 6 plugs on a TL today. Which was very easy. Maybe an 1 1/2 taking my time and wiping lots of things down. I also have a 07 Saturn Outlook which is a sister SUV to the Acadia. After reviewing your video I decide to take on the Saturn project here in the next week or so. Mine has a 176,xxx miles and I don't know if the plugs have ever been changed? Thanks again for a great, great video!

[@jpadillap1]

This is a very good video. I own a 2008 acadia and have gottoen a P0204 code. I want to replace the fuel injector and wanted to know who can tell me if the firing order for this vehicle. Is sylinder #4 the middle to the front of the enginer or to the back to the firewall? Thanks in advance.

[@raymondrandall2970]

Had my mechanic change my # 6 coil 2 times took it to the Buick dealership to find out it was the right back coverter that was bad . Just a fyi if they keep going bad it might be the converter just thought id sheir this

[@alicelang9757]

Raymond Randall Hey, curious what is the right back converter and how much did that cost you?

[@richierich8077]

Raymond Randall, curious on what you are referring to when you say it’s a “ converter”.

[@richierich8077]

Raymond Randall,My assumption is that you are referring to the the right side “catalytic converter”. Did you end up replacing your vehicles catalytic converter ? If so, how did it respond on fouling out plugs permanently?

[@rubberman2006]

My 2012 traverse has a different intake and doesn’t need to be removed when changing plugs

[@frankgryzik6162]

I would replace the manifold gasket. What your probably seeing is moisture (rust) due to a air leak....my 2 cents

[@tonystout1545]

Nice video. Just a sidenote: The plastic housing that fits under the oil filer cap is the worst design I have ever seen. Every time I needed to add oil, the cap would be jammed and could not get it off without channel locks or vice grips. I took that top plastic engine cover and threw it in the garage where it sits.

[@Canvideo]

One other check of the spark plugs is to check the resistance of the center electrode. If it is a resister type, the resister can fail, and cause a misfire.

[@ffifer52]

Great video. I have an 08 Saturn Outlook, so this is very helpful. How long did this take you in real time?

[@FearlessMods]

so long ago it's hard to recall...maybe 3 or 4 hours??

[@randalldalton5475]

How did they do all this "diagnostic swapping" for so cheap without removing the intake? and why then would they charge $400 for the plug replacement?

[@damionlimdsay9886]

from 3:25 to 3:34 I discovered the little black tube broke clean off my intake and I don't know how long ago it happened. How do i fix or replace it, what is it called and how much is it? any help is appreciated thank you.

[@jerrymack9196]

Hi, I just watched your video on changing spark plugs...great help, as I am in the process of replacing a coil ( #5 to be exact) in my 2009 Saturn Outlook with the 3.6 VVT engine. I am wondering if you could possibly tell me...which cylinder that is? Nowhere in my Chilton's does it call out the cylinders or how to count them or from what direction when facing the engine from the front of the vehicle.

[@j.keeley]

+Jerry Mack 1 3 5 2 4 6 You don't need to remove the manifold for that one. Much easier. I just replaced two coil packs on my 2009 Outlook as well. Good luck!

[@FearlessMods]

+Jason Keeley thanks for the diagram. I believe you are right, despite what I say in the video. I would still recommend changing all plugs which requires the manifold to be removed. However it now makes sense that the dealer would have been able to swap my #3 and #5 plugs/coils without removing the intake.

[@timwilliams3496]

That makes sense. I was wondering if GM was changing the gasket for each time they swap the plugs. I am going to do this work this weekend on my 2009 Acadia. I have been putting it off for a while because I keep worrying it won't start after I'm done LOL!! Thanks for the video!

[@lukecantrell7742]

Just did my 2012, did NOT have to remove the intake manifold. Used a 10 inch extension front plugs ans 6 inch extension on back plugs. GREAT video tho, Thanks!

[@FearlessMods]

Wonder if they made a mod from '09 to '12? Thanks for sharing Luke!

[@Adamlee78]

Great Video, but question... Do you have to drain any coolant before removing the plenum?

[@FearlessMods]

Thanks Adam. As for draining coolant before commencing the repair--I didn't have to. I don't recall the intake plenum being water-cooled.

[@Adamlee78]

FearlessMods no coolant needed removal. Only removing the plenum so I didn't get into the intake itself. Thanks for your video. It gave me the confidence to tackle this pretty easily. And saving $350 in labor from local GM stealership.

[@maxmcallister3521]

can you get too coil #1 without having to take intake off on the 09 Acadia?? Having a cylinder 1 misfire at the moment.

[@ramocol44]

I've been having the same issue with MINE! Just found this video while doing research. My #6 cylinder keeps filling with oil. I get a drop in RPM's and eventually have a severe loss of power to the vehicle (it becomes sluggish when I apply the throttle). Could this be a manufacter defect since it apparently keeps happening to many of our vehicles in the same spot??

[@mariahvelazquez3399]

CTCRHenderson- Hey have you had anymore issues with your Acadia. For example have you had an issue with water leak inside the vehicle? Let me know. Thanks!!

[@FearlessMods]

Sorry, moved out of the country so I didn't see you had asked a question. Answer is No, no water leaks in the car. It continued running great until I sold it right before we moved (end of June).

[@FearlessMods]

Often, a water leak in the car can be attributed to the heater core (small radiator-like component that creates your heat when the blower blows thru it). Not having the vehicle anymore, I can't check on it, but usually they're near the passenger footwell. If that's where your leak is, get some on your finger and smell to see if it's antifreeze. If it is, you've got a different job to search for! Good luck!

[@ozoctuna9787]

Is the gasket need to be replaced?

[@fathernsoncarsngunsfscg9747]

Any chance I can get the number six coil pack out without taking off the manifold? And or do you think I could just loosen the bolts on the manifold and squeeze the coil pack out? This is the 2nd coil pack that has died in 6 months. Ah GM quality

I would never loosen the manifold without removing it and replacing the gasket. It's just too easy to do it right and avoid introducing further problems.

[@fathernsoncarsngunsfscg9747]

Thanks. I managed to get the #6 coil pack out with just taking off the throttle body. Did the swap in about 20 minutes or less. Cant believe GM charges near $500 to do this!

[@srkidd12]

You should do them all and the ignition coil packs. You should also go ahead and clean the throttle body and upper intake manifold while you are doing all of this with carbon cleaner. Power steering system flush too would be good. I know, armchair quarterbacking after the fact, but just passing on info from experience. I have the 2009 saturn outlook xe.

this engine looks identical to my 2011 Enclave threw a code on cylinder 4 misfire to its either the coil of plug i will take a closer look to compare and might change all plugs and 1 coil. thanks for the video.

[@jonathanthomason1692]

Plugs can be changed without removing the intake manifold. I have a 2008 and just did it last week.

[@mario99745]

How my friend because if you do that you have not enought space to work i have to replace mine i want the easy way

[@steedums2]

08 is different. In 09 they went to direct injection.

[@rayburn6700]

seems you have the cylinder placement wrong?... number 1 is in the back left and 2 left front

[@FearlessMods]

Jason Keeley highlighted that a year ago and you are correct: 1 3 5 2 4 6

[@Mebob2001]

that liquid around the intake was prob an induction service, if it isnt done right on thes engines it will pool up in the 5 & 6 cylinder, i work in a GM dealership and thes engines are quite the piece of work, they work great! but when they break look da faq out! but a stumble can be a huge range of thing for easy stuff make sure you have proper oil level in this engine!

[@Mebob2001]

ye well dont follow that oil life system! i hope the other owner didnt but trust me change the oil at like 40%

[@brothercheerio]

@FeatlessMods do you have to replace the gasket?

[@FearlessMods]

Abel Chirino-Gomez I wouldn’t do a job like that without replacing the gasket. I don’t recall it being that expensive.

[@alialqayyim2227]

I am just wandering if I take my 2007 GMC Acadia to a mechanic to replace the spark plugs,,,, any one has an idea how much approximately it will cost for labor ???

[@Ammonepr]

[@isaulhernandez5773]

[@denniscostonsr.6790]

Great video, very helpful !!!

[@srkidd12]

Any valve covers replaced?

[@cdsbas5771]

Thanks very much for posting this!

[@soniccash1up]

so cylinder #1 is to the front of the engine?

[@FearlessMods]

soniccash1up look at + Jason Keeley's comment below. #1 is back left when you're standing in front of the vehicle looking at the engine.

[@ozoctuna9787]

Does anyone one know if I wanted to replace the Camshaft position sensor, the intake manifold has to be removed?

[@SlingsAxes]

Thank you for making this video.

[@ericernsting284]

Also found a bit of oil in hose between air box and intake wich is connected to the crank case vent a bit of blow by Im thinking .Took it for a ride runs good but it is a GM Acadia so Im use to having problems sure rides mice though.

[@luiscorrales2012]
