How To Replace Spark Plugs on 3.6L V6 Impala Malibu LaCrosse 

Best mechanic tutorial ive seen. straight forward, not alot of bs. Well done!

I'll be dammed... I was ready to unbolt that manifold on my 2012 Impala and move it out of the way. Thanks a bunch!

You're the only person I've ever seen make videos for this motor in an impala and I love you for it.

Just did this last night, no need to remove the intake. I used a spark plug socket with a swivel, made the install go much better. By the way did not drop the plugs down the hole. Load each one in the socket and slowly lower them down and screw them in hand tight to start. Outside of that this video is pretty good.

I appreciate the video and information on the rear spark plugs. I was searching for a while on the internet but couldn't really find no good video at all you are the best thank you, man

I watched this video several times just to be sure I had everything I needed before I started the job. Somehow I missed the detail of a 6" extension, so I did need to run to the store for that in order to get the back 3 plugs out. I had a 10" and a 3" on hand, but the 6" was necessary for the back. Great video and you saved me a lot of time and cash.

Thanks for taking the time to help others by creating and posting this video, I can't see why others are criticizing carefully dropping the plugs in place, I really don't think that will change the gap that easily. I myself would probably use a spark plug socket with the rubber boot inside but that's me working on my own car and taking my time while not doing a video. Thanks again.

Awesome explanation. I remember on previous years vehicles with a v-6 engine you had to loosen the motor mount and tilt the engine forward to get access to the back spar plugs

I was thinking I was ready to do this after work but after watching your video I'm in so much need of a magnetic tool grabber. thank you so much you saved me hours of what to do's if i couldn't get the plugs out.

Great video. I don't think I would have tried those rear plugs if it wasn't for your helpful tutorial

Great video! Very well explained and demonstrated! Just did plugs and coils on my 2012 Impala 9c1. No problem. Thanks for the help!

Thanks man. I couldn’t find any help for this model at all. This is the only video that helped, I appreciate it. Straight to the point, step by step thanks man

This vid is great. It helped me get the job done right and it saved me tons of money. Thnx for posting these videos.

Y're the man, thanks buddy. U R so professional! I did the same for my honda pilot [no intake removal]. When I took it to the shop, tech. insisted that no way except to remove the intake and will cost $350 cuz "alot of works"... LOL!! It costed me $33 plugs and tools within 1.5hr to finish (first time)...

so I changed the spark plugs already!!! the most challenging one was the one from back that is in the driver's side, but got to it, and In barely posting cause I also changed the oil, once again thank you for the video, and keep coming with those videos of the impala please

Thanks for this vid, for the first time ever I did my own spark plugs, this POV style camerawork was a big help to visualize how to get the back 3 plugs out.

Thanks for sharing this video! Now I'm confident to handle this job myself 👍

Thank you so much just did my 2012 Malibu I appreciate all your help. check engine light came on went to AutoZone misfire on number four.six new plugs and the car hasn’t run this smooth in a long time was lucky enough to have the old spark plug socket with the rubber boot inside held the plugs fine

Great video man! Just what I needed. Thanks!

Thanks for the clear right to the point step-by-step on changing the plugs without a bunch of BS great job

Thanks man, ppl were saying you had to do a valve cover gadget job to access the rears. Also nother guy said you have to loosen the motor mount to tilt the engine forward then ratchet strap it in place. BS. Thanks for the video man. Hate trolls.

Super easy luckily I work in a body shop so I was able to borrow everything you used the back left one under that wire was tight but I got it. Thanks a lot saved me $300 bucks

Excellent video and clear understanding of what you were doing in changing the spark plugs....I have an old body style 2014 Impala limited LTZ 3.6 and I looked at the back side of the engine near the firewall and it looks like enough clearance to remove the coil packs and plugs just as you did without removing the intake manifold, I have not done this yet but have 94,000 miles on it and may even wait until 99-100,000 miles before I change them....Thanks for the video.

thanks for the video buddy!!! I've been searching a video for my 2013 impala never found one, great video man and any fixes you do to the impala, try to put the video, maybe it'll help me down the road, great video and subscribed!!

Gotta say I'm very impressed with how you did this. I just purchased a 2007 G6 GTP with the 3.6 engine. Although I'm not gone be doing plugs myself. Paying someone $50 dollars to do them. But I do know if ever want to save that $50 now I can do it myself.

Fantastic Video! Really appreciate your tutorial and efforts!! Was quoted approximately the same $500 and was reluctant to try this repair due to having to remove the intake. Believe i will now give it a shot wven with my limited mechanical skills🤙

Awesome video bruh, keep them coming, this was the best and straight how video I've seen in a while!

Great job man. I have a 14 with the 3.6 vvt. Wasnt lookin forward to this job. Now.. im not dreading it. Thanks

Very nice video, no bs, straight forward with no fluff. The trolls with dropping your plug in, I didn't see you do it. Putting the plugs in with rubber tubing is the best way though.

Awesome Video. Thank you for posting!

Thanks so much for this. Was thinking the intake was going to have to be removed in my Buick LaCrosse. Awesome to learn that's not necessary!

Great video really straight forward simple and informative.

I'd say this is the BEST video I've seen on removing the coil packs and the plugs - great job. You think the gap is going to change when the plug is dropped into the recess? NEVER in hell! "Auto Rex," best damn video I've seen - keep it up! Thanks.

Thanks so much, changed them today. I did get a magnetic spark plug socket.

Just saved me a ton of 💰!!! Thank you so much!

Excellent video. Thank you for making this and sharing it.

I'm on my 3rd impala, more that 230K miles on the first, 80K on the second before it was totaled. It was really easy to change plugs on the pre 2016's 3.5L by pulling the engine forward, only had to remove one bolt. These are really really reliable cars, Good video as I'm changing the plugs at 125K miles on the 3.6L.

Going to tackle this job tomarrow, Looks easy enough, Thanks

Thank you...you do great work! Good work ethics

Great video!!.step by step awsome.I've seen other videos where they loosen the motor mount and tilt the engine to get better access to the rear spark plugs.Its good to know that wont be necessary.Thank's

Thanks alot, you saved our time and money

Helpful video!!! Keep up the good work!!!!

Very helpful video, just add a magnetic 5/8 spark plug socket (autozone $6.99) for the old plugs out and new in, and pull the red clip and push the white part and remove the brake booster line which snaps right back on after

Nice dexterity on the back three. Looks like it’s doable. Thank you

repair shop just told me " the intake plenum needs to be removed to do rear plugs" $500. nope nope.

Excellent video!

Thanks for the video. Saved me some time & extra work. I put my anti seize on mine cause when I had my 2003 chevy malibu. I couldn't get them out but I guess your only suppose to put anti seize on when you got aluminum heads. Oh well,it's done & has more power. Hopefully she last another year or so

Thank you! Great video!

This is great! I was thinking I would have to remove my intake.

Hey that was pretty good and straight to the point!😂 Thank you!

Wonderful video, it saved me a lot of time. Would you happen to have a video or know how to test the coils? I noticed that there are 4 pins and I have only ever seen 2. Any advice would be appreciated.

Its very easy just like he shows.had it done in about 30 minutes pick up a magnetic 5/8ths spark plug socket worth the $6

Thank you so much for this for this video ! For the very last spark plug you did (back plugs) did you disconnect the cable that was sort of blocking it?

Hey I need to change my fuel injectors but don’t know how to take the intake cover off to get to them. Do you have a video on that?

Great explanation, thanks!

Great detailed video

Well done video.

great video dude, thank you!

Awesome Video. Thank you. Do you have to change the oil as well??

great job, thank you

Thank You, my 232K miles 2014 Impala Limited LT on original plugs will appreciate it!

Thank you your video was really helpful

awesome video 👍

Great video. Would you recommend doing this without a torque wrench?

Very well done video! Could you do a video on how to change ignition wires, O2 sensors, and air and cabin filters?

Great video. Ignore the "don't drop a plug" critics, while they may be right, I think you just kind of settled it gently in there, lol. The main thing is - you showed the method, and that saved a ton of time and money. Nice job!

HUGE Thank you...

Good video editing

Excellent video. Blessings.

Great Video. Currently have the car (2011 Lacrosse CXS) at the mechanic and it's going to cost $636 to change all 6 plugs. I hope they are are replacing the air filter too??? I'm 72 and not mechanically inclined and don't have any of the tools.

nice work thanks!!!!

Great video thank you very much .

What tools will be needed

I have 09 Saturn Aura XR with the same engine. I paid a local shop $600 to replace the plugs and coil packs at 120K miles because I was told that the intake had to come off. Fast forward a few years and another 100K miles. Car started misfiring under load. Watched your video and even though the Aura is a bit more cramped and I had to pull a couple evap lines had them all changed (plugs and coils) in about an hour. Looks like the shop that did it last time didn't change the packs (it still had the originals even though they charged me for new) and screwed up the plug gaps as well. No two were alike, with a variance of over .015 from the least to most. Never going back there again.

Just changed the plugs, and thanks for the tips. Went easily, but i used a 3/8 dia rubber hose to drop the plugs in 3, 5 cyclinder. My 6" extension and 5/8 sparkplug socket with spark plug didnt have enough room with the firewall and vacuum lines. But thanks again for sharing this technique.

What if you got oil Coming from the middle front coil is it the valve cover gasket or the Coil gasket

I have a 2015 Impala 2LTZ V6. I'm going to change the plugs on it. Is replacing the coils and wires necessary?

I have a 2007 Saturn Aura 3.6 LY7 motor. Would this be the same?

Very helpful

Would this be the same for the 3.6L V6 in the Saturn aura XR? I read somewhere else that the engine had to be rotated forward to get to the back.

Thank you!

Nice video!! Also I have a 2016 impala ltz and on the Chevy app it says “Antilock breaking system” is that because my battery is low?

i did mine saved me some money on my 2010 Hyundai tucson

Would this be the same on a 07 Saturn aura xr since it’s the same V6 and layout because i don’t want to pay $700 to a shop to do it

Will this work on a 2013 Buick Lacrosse with the same engine?

I had my spark plugs changed for my 2013 impala by a local mechanic and he loosened the intake to get to the back spark plugs. After changing them and torqueing the intake bolts in, the car started fine but the next day when i started driving again everytime i give it light class when accelerating from a complete stop it makes a mild ticking noise. Could this be a sign of poor spark plug installation? The ticking sound only comes when I accelerate on local roads, not when i’m idling or driving on the freeway

Will this work for the newer generation? I have a 2016. The intake assembly is on the other side.

liked n subbed. thx!

Ty,,im about to do mine

How about 2015 chevy impala 3.6 lt new body style one rear plugs

Good video. But a few things to remember. Never drop a plug in. Changes the gap by hitting the head. Also, if someone were to buy iridium plugs -these types of plugs are pregapped (Common choice).So by dropping the plugs in like that ruins them and they will need replaced.

Have you replaced a variable valve camshaft solenoid on this motor if you have please let me know thank you

Mine has a loud rattling noise only on cold starts, so many say that’s normal on these engines, is that true??

I’m trying to reach my rear spark plugs. I have a 2016 Impala LT, V6, 3.6L. One is under some stuff and can’t be reached unless something is removed

Will this procedure also work for a 2007 Saturn Aura with the same 3.6 V6? Will there be different or additional interference for the back plugs on Aura? I appreciate any feedback!

Intake alot bigger on lacrosse cxl. Not sure how this would work on that application?

Thank you for the tips. Do not forget to put dielectric grease on the boots and I use anti seize,always on the plugs threads.Just old school here.Done in less then an hour.

Is it the same for a gmc terrain?

I had to remove intake because of the coil on #2 cyl wouldnt come out ( 2014 impala new body style) because the throttle was in the way. Still.. i went into this with alot more confidence. Thanks

Trying to help out my gf's grandma and change the plugs on her 14 impala with a 3.6. Has a different intake and can't even see the far passenger side coilpack. Hoping i don't have to take off the intake but currently not sure yet.
