How To Change 2014-2018 Silverado Sierra 5.3 6.0 6.2 Spark Plugs (3rd Gen)

The long requested spark plug change video is here! In this video we change the spark plugs on Cliff's 2014 Silverado with the 5.3L EcoTec3 L83 V8 motor. The process used in this video should be identical to the 6.0L V8 and the V6 Silverado and Sierra Models as well.
This process should be identical for the following vehicles:
2014 - 2018 Chevy Silverado
2014 - 2018 GMC Sierra
And very similar to many other GM trucks like the Tahoe, Suburban, Escalade, and Yukon.

[@TheSundaeDrive]

Gap between 0.037-0.043 in. Even with factory plugs, it is a good idea to always verify you have the correct gap

[@19Photographer76]

The #8 insulator seemed to have some carbon staining that the others didn't have, any thoughts on the issue?

[@drdizzy888]

Absolutely, with my race car the gap seems to be spreading periodically just from driving itself after certain amount of miles. Always good idea to check those suckers as they will put a strain on your performance.

[@DrDennis]

Never touch these plugs concerning the gap. You can ruin them easily.

[@TheSundaeDrive]

If you know how to gap them properly you won't damage them. We've installed thousands of colder spark plugs on boosted applications and have maybe damaged one. You have to know how to do it and have the proper tool tho

[@williepelzer384]

Replace the wires too

[@NorthernChev]

You are the ONLY video on KZbin that had the bawls to actually SHOW the #8 removal and replacement. Props.

[@stevestringer7351]

No! There is another guy that recorded that as well..... it was enough to convince me to get a professional to do this for me. In my younger days I would have at least attempted it..... but now.... I would just rather have someone more mechanically inclined than me do it.

[@TheSundaeDrive]

Happy to help guys!

[@PaffordHomestead]

I'm going try this myself because they want 450.00 here to change them

[@newfinishautospa]

I don’t understand why it would be an issue…

[@juelzreyes4638]

WRONG, I’ve uploaded a video easily removing the #8 spark plug without taking off the passenger tire

[@charlesmaroon8819]

I always start with the most difficult plug. This way you are not tired, frustrated or suffering from bleeding knuckles by the time you get to the hard part. When this fellow finally does change the plug wires they will have near 200k miles on them. Might as well do the job right the first time. Take your time, work carefully - and safely.

[@michaelchilds1115]

Whatever happend to just working on trucks not having to take 6 parts off to get to one. Keep it oem. Good video.

[@TheSundaeDrive]

Thanks! I'm just happy it was easy to get to with the fender liners off lol

[@TheSundaeDrive]

Same on my truck. Annoying

[@bikekid11]

I just changed all my spark plugs from the top didn’t remove the fender line. Though I had my knees on the radiator cover

[@linc2356]

Exactly I remeber climbing into the engine bay of my c10

[@deanclippard2963]

When I saw him remove the splash guards I said to myself... OH No!!! But from there on out it was Easy-Peezy! Great Video!

[@TheSundaeDrive]

Haha thanks! Glad it helped :)

[@Freedom.z.z]

same!

[@stephencannon3140]

This sounds like one of those things that you should resign to the fact that removing the tires and fender well liner is the quickest way and move on. Spend two hours trying to be a hero or spend 20 minutes raising the vehicle, removing the wheels and another 1+40 actually removing and replacing the plugs and wires

[@stephencannon3140]

No Air/Impact or electrical tools were used or harmed in the Fi lining of this video. Good call. Even if you use cordless DO NOT use them to break or apply torque. In my case I can have it already threaded out by hand in the time that it takes me to find the cordless drill. Even longer when I realize that the drill I found has a dead battery. A tip from another video recommends doing something like this during the day while stores are open, especially if you accidentally cut or tear a wire. I personally would have new plugs and wires on immediate hand just in case...if not used they should be able to be returned.

[@TheSundaeDrive]

That's always a good tip when working on your primary vehicle. That has saved my butt countless times lol

[@Stephens215]

I replaced the spark plugs in my 2014 GMC Sierra using this video as a reference. It worked GREAT ! ! ! Removing the tire and mud guard was simple and definitely made replacing the spark plugs easier -- especially that last one on the passenger's side of the truck. Thank you for the video.

[@TheSundaeDrive]

Excellent! glad it helped

[@scottamy6496]

Pregapped plugs or not, I highly recommend verification of the gap regardless...

[@TheSundaeDrive]

Agreed 👍👍 regretted not doing that almost immediately. It's been running good at least 🤷🏼‍♂️🙏

[@misterblack6521]

Fuck yeah and check for cracks.

[@sarahpoisel6734]

Always. A$$hats are moving them all over the world.

[@cameronjones3155]

Definitely following this tip from now on. I believe im having some crankshaft &/or cam shaft sensor issues with mine but decided to do the tune up to make sure since the plugs & coils hadnt been changed in ages anyway.. welp, i bought pre gapped and never verified gap, still running the same issues, now i gotta take em out and verify gap and put em back in... if only i woulda you know, done that to begin with... gotta stay busy out there.

[@alexengstrom4503]

Thanks man! Getting ready to do mine in my ‘14 5.3. My dad turned wrenches for 35 years. A trick he showed me for getting plugs started if you don’t have room was use a piece of fuel line that will slip over top of plug and use it to get threads started.

[@WhiteRhino0589]

Best old school trick and nobody uses it

[@matthewspence9969]

When I saw he had the wheel and fender guard off, I said to myself, “NOPE” due in no small part the fact that I’m a dumbass. And started taking them out from the top. The first 2 went in great, then the third back on the drivers side nearly had me in tears thinking I’d cross threaded and damaged the head, because I couldn’t get the new or started. So... then I decided to go back and start watching the video again. Took his advice and finished in about an hour. Thanks!!!

[@TheSundaeDrive]

You got it! Sometimes a little extra prep makes it a lot easier.

[@DIYAmateurHour]

For anyone thinking that you can just change the spark plugs from the top, it took me an hour and a half to do the driver side from the top. It only took me 35 minutes to do the passenger side through the wheel well. Many thanks to this guy

[@TheSundaeDrive]

Glad to help! Passenger side is way easier from the side for sure

[@ericpigg2689]

Why did it take so long to do the driver's side? Those are cake.

[@paulradice3534]

Did mine from the top, wasn’t that difficult. Amateurs are funny people

[@eyewelderboat7872]

Hour and a half because you are a beta male😂 should not have taking that long for (1) side Smh

[@travisgrime6834]

Many props for showing how much easier and faster it is with the front tires and wheel well covers removed. That is the ONLY ONLY ONLY way to get to #8 unless your arms are actually made of rubber and it simplifies the other 3 on the passenger side exponentially. Great job👍🏻

[@markmcleod5079]

Definitely looks easier for this old man than climbing on top of the engine. 😃. Thank you for the video!

[@chrisshealy87]

Man this video is super helpful. I spent today doing a tuneup to my 2016 Silverado and I’ve never felt more confident going into a project. I’ve only changed the spark plugs in 1 other vehicle and that was a ‘97 4Runner. Love this video, just subscribed to the channel.

[@TheSundaeDrive]

Appreciate that! Glad to help out the community!

[@RaptorSucc]

This video helped a lot, I'm 17 and for this being my first job, the process went smoothly. No check engine lights and now I want to be a mechanic.

[@TheSundaeDrive]

Awesome! Glad it went well!!

[@J24777]

@@TheSundaeDrive So, when do you change the Coil packs?

[@jcortes3930]

Don't, choose another profession

[@TheSundaeDrive]

I'm not sure when the recommend change interval is offhand for the coil packs but mine are still good at 120K

[@dannyt1705]

Always use compressed air to blow dirt and grime out of spark plug well before taking out the spark plugs . You dont want any of that falling into cylinder when you get plugs out

[@TheSundaeDrive]

Very good point! Should have done that for sure.

[@steveobrien8792]

I would have never thought to remove the splash guards and go in from the wheel well. I'm a long way off from 100k on my 2016 but when the time comes I feel very confident

[@TheSundaeDrive]

Glad it helped you out! It definetely makes the job significantly less of a headache.

[@camshaflober3691]

Tip: i use a piece of fuel line about 10 inches long to put on spark plug end. It Is a lot faster than turning the ratchet 10,000 times

[@TheSundaeDrive]

Yup! I've used that method before. Definitely a good way to get them out after breaking it free

[@carlosfunchess5462]

Change my plugs and wires a couple of days ago using this video with no problem in less than two hours! Thanks!

[@TheSundaeDrive]

Awesome! Glad it helped!

[@carlosfunchess5462]

The plug wires that I took off had the GM part# 12660508 but the replacement GM part # 12633447. It is a 2015 Chevy Silverado 1500 that I bought used from the dealership with 102,000 miles. I assume the wires were the original ones from the factory so should I go back with the old ones? Thanks.

[@vikkleo]

Yup I use his video for helpful hits also great hands on vid

[@TheSundaeDrive]

Glad it helped!

[@TheSundaeDrive]

I would inspect the wires, if the rubber still looks good and not dry rot you should be ok. My wires appeared to be in good shape on my 24 still

[@johnnyvonwahlde463]

Outstanding! Really appreciate you taking the time and showing the proper way to change the plugs.

[@TheSundaeDrive]

Glad to help!

[@johnhoffman8421]

Great video! Consider old hot rod trick of using 3/8” rubber tubing (8-10” long) over plug insulator as a leader to start / remove plug. Gripping is tight, and can’t cross thread in hole. Helpful on deep hole plugs (hemi heads) and trim to fit ugly tight spaces...

[@TheSundaeDrive]

Thanks! That is a good suggestion. I have used that method on some other vehicles and it works well

[@AcmeRacing]

I was going to make the same comment, but you beat me to it.

[@rtkmorris]

I use an old spark plug boot. It's a trick that i learned from an old timer when i worked at the Chevrolet house years ago

[@JimThomas-o4x]

Mac Tools makes a small rubber tool for the same thing- probably no better than the boot or a length of fuel line hose, but something cool to have in the box. @@rtkmorris

[@williammcintyre6501]

Yeah I just changed mine from the top like people have been doing for the past like 100 years. Don't have time to do all that extra shit. You do you though.

[@JohnDoe-ys3ed]

The owner’s manual says to change them at 94k miles though…🤷🏻‍♂️

[@jakmarlin8233]

Great idea removing the fender wells. I never thought of that. Passenger side rear plug is a bear! I'm still not sure how I did it. One caveat: User anti seize on spark plug threads always. It is a very important step.

[@TheSundaeDrive]

Thanks! Glad it helped! Actually ngk says never to use antisieze. It's fairly controversial lol. A few other comments get into it.

[@jarrrr69]

I have learned to just put anti seize around top of the treads because that is the only place the rust or corrosion is going to start.

[@SilverDollarSaloon]

I always use antisieze on bolts and spark plugs that have to be removed later to do maintenance.

[@cw6656]

Man great job! You are brave sir. To lay those plugs on top of the rotor like you did. I treat plugs like eggs. Do not want to crack one!

[@TheSundaeDrive]

glad the video helped ! lol you definitely want to be careful with them

[@SilverDollarSaloon]

The driver side can be done with removing the spark plugs from over the top the engine.The passenger side is easier as shown through the wheel well because of the difficulty of the number 8 spark plug.

[@TheSundaeDrive]

Yeah, I've done it a few more times and from the top on the driver side is easier.

[@charlesnavarrette1835]

I did all mine from top used a piece of foam rubber to lay on broke loose with swivel lock head ratchet and 3/8 cordless ratchet reinstall with finger and socket then cordless and tighten final with ratchet #8 1 inch extension on socket and 3/8 stubby ratchet took about 1 hr and 20 min with out pulling tire s and wheel well liners

[@TheSundaeDrive]

Haha thanks!! We are trying :) share to your friends 😉😋

[@alexmiller657]

Or you can do what I did and struggle on the last spark plug without removing anything. Takes just as much time as taking my wheel off that is most likely glued onto my hub and stripping out wheel well liner screws

[@TheSundaeDrive]

Lol yes that's true too

[@cannon2695]

Dealership told me my truck used AC Delco 41-168 not 41-114 ( 2017 GMC Sierra SLT 5.3 ) Very confusing trying to find info on this.

[@TheSundaeDrive]

Not sure, all I can say is I've had no issues with the plugs we used.

[@monctonstrong8423]

go with what the truck VIN calls for, your dealership should have ask to make sure its the right ones

[@armanhaan2296]

You don't really need to take off the tires; just remove the passenger side inner fender since the passenger side plugs are harder to reach; the driver side plugs could be easily accessed from the top.

[@TheSundaeDrive]

Correct, no need to remove wheels and reaching the driver side ones from the top aren't bad.

[@viixiconik]

Any recommendation on 5.3 2014 spark plugs? High performance type maybe?.

[@TheSundaeDrive]

NGKs or ACdelco are good. That's what we normally go with

[@waynegarrison2481]

I changed mine like you did. The only thing I did was put never seize on each plug. Check the gap. Shipping can effect it sometimes. If the new plug is a little offset use a piece of gas line hose on the plug to turn it in

[@TheSundaeDrive]

Agreed on checking the gap save regretted not showing that in this video. Be very carefully with anti seize to bit overtighten

[@waynegarrison2481]

I've been a Ford guy since 1972. I will NEVER buy another one. Out of 2 v8s 14 plugs broke off

Always a good idea to put a dab of anti sieze on spark plug treads

[@darianthompson5975]

Do you not like electric ratchets? I have a bad shoulder and they make everything easier

[@TheSundaeDrive]

Yes they do! And we have them but since most people don't we like to show it with hand tools.

[@josephasantucci8154]

just what I was thing, take the time and remove the inner wheel covers saves a lot of time and aggravation thanks

[@MrZipperhead16]

NOBODY uses a torque wrench but you do you. NEVER trust the gap is correct. Check them anyway and, a little dab of anti-seiz or silicone grease on the plug threads will help keep the plug from corroding to the head.

[@TheSundaeDrive]

Agree you should always check the gap and I regretted not showing that in this video. Spark Plugs are on thing I always use a torque wrench on especially when running a shop. It is not worth the risk of someone overtightened and breaking one off.

[@BadAssEngineering]

Researching before changing mine, I discovered that the stock 12633441 spark plugs have a reach of 17.9mm But the NGK and Denso "equivalents" have a reach of 25mm. This bothers my OCD and now I wonder if putting NGKs or Densos would be problematic because of Piston Interference

[@TheSundaeDrive]

I haven't had any issues with the plugs I installed. They've been in for over 10K miles now

[@solarmantint1965]

I didn't take any wheels off I didn't remove any fender wells, I just did it the old-fashioned way just got up in there and did it and it took me about 30 to 35 minutes and I was done.. it helps to have different extensions,,, but overall, I guarantee you I would have had my plugs changed before you guys got the tire off and the fender well cover.. I'm not trying to be rude or anything like that, but, it's just a lot of added work that doesn't really need to be done. It might be okay as far as doing that with the number eight, but, you still don't need to do that much work, and, just go ahead and replace the wires while you're at it don't wait 200,000 mi or 8 years

[@TheSundaeDrive]

Thanks for the input! Defintely don't need to remove the wheel. we only did that for better filming angles. I have found that the driver side is easier fromt he top because of the steering shaft and passenger side is easier from below. and wow - 200K is def a long time lol

[@mikerobbins5049]

Years ago I would have done this but as I get older, I tend to let my mechanic do almost every thing. I still change oil and do brakes. I will also rotate tires some times.

[@jaredthacker3937]

I thought the plug behind the steering linkage was a lot harder than the #8 plug on the passenger side. I did get to torque #8 using 3/8 drive tools at least.

[@TheSundaeDrive]

Going from the top on the driver side is a bit easier

[@ericpigg2689]

I put a spark plug socket on number 8, then I use a 3/4" socket on the hex of the spark plug socket. I just use a regular ratchet on it and go from the top. I don't bother with removing the wheel and the inner fender. The driver's side is super easy. The passenger side is a little tighter. If you do want to remove your inner fender, buy some of the plastic pop clips ahead of time. Several of them will break, especially if your vehicle is several years old.

[@TheSundaeDrive]

Agreed, driver side is easier from the top. Removing the wheel is definitely not necessary either way

[@officialnotonlyjames]

im confused why you can't reach from the top of the engine, I mean it is easier with the wheel off but like, just put a chair to reach them.

[@chrisshealy87]

You can reach them from the top but that side angle makes the job easier.

[@TheSundaeDrive]

Driver side I have found is easier from top and passenger side from fender well

Great video, very nice quality on how well you can see everything going on

[@RWet-cr3mw]

I'm surprised you didn't mention blowing out dirt around plug before removal, ( to keep dirt from falling into cylinder, I admit, with these mounted horizontal, it's not the biggest concern), and using 1/4" rubber hose on top of sparkplug to start it into threads.

[@TheSundaeDrive]

That isn't a bad idea for sure - I've never had an issue on this motor with that due to the angle but always better to be safe!

[@MatthewSenneke]

The fact you have to take all this off just for the spark plugs is ridiculous, these new engineers are garbage

[@theonly9]

Thanks for the video, I just swapped all 8 of my plugs and I have to say the 8th one is not nearly as bad as people make it out to be. Try changing the plugs on a WRX then you'll know what hard is.

Yeah, WRX is a pain in the butt. We have a video doing it on my brother's lol

[@joseocabrera4313]

Excellent video and very well explained. I have a 2014 GMC Sierra SLT 1500 5.3 I'm about to change my spark plugs and wires, ¿do you think platinum spark plugs are better than AC Delco and in your video did you be able to torque the spark plug number 8 ?

My truck has 7 of the 8 removed and obviously it’s #8 that I didn’t do. I just felt wiped out going from the top w/o removing the lower mud guards to even want to try until now. So I am just going to do it the way you showed today and hope it works out. Changing my plugs at 77,000 made a huge difference in the engine running smoothly now I just need to finish.

[@levihale3915]

Ever figure out what the purpose of that "heat shield" around the sparkplug boot? Grabbed some MSD plugwires and high temp protector sleeves instead of reusing stock 🤷‍♂️😂 Day 4 no problem yet

[@TheSundaeDrive]

I think it is too keep them from cracking due to the heat probably

[@MrJLewis59]

Thanks for sharing your knowledge with this video. I used it for reference with my 2016 GMC Sierra Denali 6.2 with some slight tweaks. 1. In addition to removing the inner fender and the bazillion 10T torkx screws, I also had to remove the exhaust manifold heat shield to get to the back 2 drivers side cylinders plug wire heat shield. 2. I cut to the chase and did the same thing to get to the passenger side cylinders and it makes the overall process easier IMO as it provides more room for the tongs to get the spark plug heat shields off which honestly was the hardest part of this job. 3. Be sure to check the gap on your spark plugs. I bought TRQs and every one of them had too small of a gap per factory spec.

[@TheSundaeDrive]

Appreciate the tips and glad it was helpful!

[@talofath]

change the spark plugs, 2015 chevrolet silverado 5.3L V8 started fine... when leaving the shop the check engine turned on... and the engine lost power... it generated a P0300 code, the engine still has not stabilized... which could be failing?

One advice, don't "necessarily" trust buying your AC Delco's from eBay at a discount, I played cheap and did that, and I'm 99% sure they were counterfeits....now in the garbage :-(

I don't know why, but I watched this video this morning after changing the plugs last night. If you prefer to wake up with the backs of your hands scraped and raw, and your entire torso sore as hell, you can do it from the top. Just make sure you have a couple full length albums to listen to, and tell your spouse you will be a couple hours late to dinner. Hope I didn't tear anything up on top of the engine. I did get #8 from the bottom, but without jacking the truck up or taking the wheel off, just laid under there and fought it. Took about an hour just for #8. Wish I had seen the video first!!!!!!!

[@TheSundaeDrive]

now you know for next time! I will say, the drivers sider is easy from the top but the passenger side is definitely easier from the wheel well

[@ClaytonBigsby01]

Yeah I'm going to watch a how-to video from a guy who's never even done the job before😂 and holy shit before I get done typing that sentence you're taking the fucking wheel off on for a spark plug job😂 now you're taking the whole fucking truck apart

[@stevestringer7351]

Great video. I really appreciate the patience that you use to describe the process. Though I will probably have someone with more skills than me change my plugs and wires, it never hurts to understand the proceedure. I am n new subscriber. When you do a tune on your truck, i would like to know how that goes. Have you already done a video on that or is it still to come?

[@TheSundaeDrive]

Happy to help and welcome! Video isn't up yet but it will be this summer

[@D2O2]

Just did my '17 all from the top, about 1 hour total. No other parts needed to be removed. Wheel well approach provides better body positioning, but more parts removed.

[@TheSundaeDrive]

Agreed 👍 less reaching for stuff from the bottom but can be done from the top

[@Nathan-wn5mc]

You were able to reach your #8 from the top? Is the 17 designed different from the 14?

[@TheSundaeDrive]

That part is the same on the 14-18 model years. It can be done from the top but a lot easier to reach from the side.

[@Nathan-wn5mc]

@@TheSundaeDrive Thanks for the advice, I just bought the truck a month ago. It has high mileage and want to change the plugs. I would try your method as it definitely looks easier but unfortunately my truck is lifted and is going to be hard to Jack it up. I'm assuming climbing in and out of my engine bay is going to be a challenge as well.

[@TheSundaeDrive]

If you are lifted you won't need to jack it up :) just remove the fender liner and you should have full access. A lift will make it far easier 😉 just turn the wheel if needed

[@scottgorski7931]

I'll once again have a use for my 36"- 3/8" drive extension. Plus the 5/8" deep swivel socket.

[@TheSundaeDrive]

It isn't a terrible job. I have found that the driver side is easier from the top while the passenger side is easier from the wheel well.

[@williepelzer384]

What if the box got dropped , so much for the correct gap

[@TheSundaeDrive]

Agreed. I regret not showing how to gap in the video

[@sodbuster518able]

Not necessary to remove drivers side fender liner easy access from up top,yes for passenger side especially #8 cyl is the worst

[@TheSundaeDrive]

Agreed. Having done this a few more times, I would say the driver's side is easier from the top and passenger side from the wheel well

[@jnavarro3059]

I thought u always had to buy new spark plugs wires everytime u changed out the plugs?

[@TheSundaeDrive]

Spark plug wires don't wear out due to mileage like the plugs but age. It doesn't hurt to replace them but they should last more than 5 years or so which is around when I replaced my plugs. I'll probably replace them on the next plug change.

[@misterblack6521]

I use rubber tubing on end of spark plug, so not to cross thread it while inserting. Also use a dab of anti seize not a fucking glob.

[@TheSundaeDrive]

tube is a good trick I've seen used often. A dab shouldn't hurt anything but given how controversial the use of antisieze is we decided to play it safe and leave it out as the newer coatings on spark plugs are not supposed to require antisieze

[@lachomedina9048]

Very very helpful video I like this video because you are showing step by step to remove all 8 sparks plugs and how to get them in the easiest way and one more is more easy to do the job when you have the right tools. Thank you so much for you video.

[@TheSundaeDrive]

Glad it helped! I will say after change the plugs again, the driver side is easier from the top but passenger side from below is way better

[@miguelrivera8436]

Good video.... I work at Chevrolet Mazatlan and Tomorrow morning i got a Silverado waiting for me to replace the spark plugs.... but this video just Made it easier for me.! Thanks

[@TheSundaeDrive]

Awesome! Hope it helps you out!

[@davidcampbell1899]

Well, at least you wont need to do that for another 4 or 5 years. WAPITA!

[@TheSundaeDrive]

Annoying for sure. A tiny bit more clearance around the engine in general by the firewall would be nice

[@brandonnguyen1486]

Is it worth spending more money for higher end spark plugs, and if we don't have a torque wrench, just snug it pretty good is ok?

[@reachingoutministries1134]

less work if u just do it from the top with a small 3 step ladder. no need for tire and fender liner removal.

[@tyleralexander7842]

What just helped me a lot for that #8 is I used a socket adapter for a drill & a quarter inch socket. If anyone is trying to figure out how to get in there

[@cjroberts7022]

what is the gap supposed to be? I can understand that its pre gapped, but maybe at least mention what the gap is and encourage us to dbl check

[@TheSundaeDrive]

0.037-0.043 in and yes I should have encouraged that for sure. Thought I had mentioned the gap in the video but went back and watched and realized I did not. Always a good idea to double check.

[@monctonstrong8423]

Well changed my plug in my 2018 Sierra by taking both front wheels and liner out, I wanted to clean and rust proof the fenders and it made changing the plug very easy, 3 hours and I wiped out everything, found 3 plugs out of wack with one half missing tip so don’t wait too long to change yours, I had 103,000 miles on mine, the best part it took the ticking noise away and idles much better

[@monctonstrong8423]

I checked the gap on the new AC Delco 41-114 ones and surprisingly they were all within specs, and don't you guys dare use any type of lubricant or anti-seize on the spark plug threads, that will make you over torque them and stretch out the block threaded holes

[@TheSundaeDrive]

Agreed! Glad it helped!

[@fredjanssen4281]

just saw the video again seems very thorough easy to see with the stay at home order this is a good time to do this I do most of my own work on my vehicles this looks fairly easy I have all the right toolls so here goes will post follow up

[@TheSundaeDrive]

Awesome! Best of luck :) plenty of time to do maintenance right now with the lockdown for sure!

[@joecz3918]

Is this your first plug change on this motor at 90k miles or do you recommend and lower mileage plug change?

[@TheSundaeDrive]

It's not boosted so you can go a fairly long time between changes. GM recommend 100K I think if I'm remembering correctly

[@bikekid11]

Great video. Though I did it all from the top I didn’t remove the fender liners. On another note you should use inhibitor not dielectric Grease. Dielectric grease is an insulator not a conductor. Inhibitor is conductive just don’t get it all over then it may track

[@TheSundaeDrive]

Having done it a few more times I've found that the passenger side is easier below and the driver side is easier from above. Thanks for the tip!

[@monctonstrong8423]

the difference between dielectric grease and conductive grease is conductive grease is more of an anti-seize grease with metal in it and dielectric has no metal in it@@TheSundaeDrive

[@cehuddl]

Fantastic way to remove and install plug #8. Thanks for the video. Really helpful.

[@TheSundaeDrive]

Glad it helped!

[@MyUserTubeAccount]

this is f**king ridiculous... these manufacturers are pricks making this routine maintenance this difficult. sigh

[@jonienglish3231]

You would Think the IDIOT ENGINEERS at GM would have Sacrificed Passenger Foot Space 2 -3" and Give More Room in the Engine Compartment for #8 Spark Plug Removal

[@TheSundaeDrive]

Even one inch would be nice. Lol

[@jonienglish3231]

@@TheSundaeDrive i removed the Transmission out of 1st GEN GM Hybrid Truck , NO ROOM there was No Starter Motor - the STATOR BURNT OUT !!!!! on Normal Trans only Needed 1/2 INCH for Trans to Slide out the HYBRID NEEDED at Least 3-5" to CLEAR the Stator - but the Firewall PINCH Seam was in the way .

[@mariorodriguez560]

Will be doing this to ‘16 crew cab I’ve had it for 4 years but I’m picky at 54k miles, just wanted to see what was the easiest less stressful way to do this also doing my oil and filter just did my air filter last oil change got keep em running smooth I’m picky when I start hearing or feeling non normal noises great video 👍🏻

[@TheSundaeDrive]

Thanks man! Hope the video helps you out with yours!

[@muhanadshaaya4625]

Soooo helpful. Im a second year at GM and gotta do that tomorrow. Was already struggling with it this afternoon.👍🤝

[@TheSundaeDrive]

Best of luck with it! glad to help!

[@BULLET2246]

My suburban has ac lines going along the #8 spark plug. Yours doesn’t.

[@tier1detailcompany]

Great video, thanks for taking the time to make it. Gotta throw new plugs in after supercharging so this is extremely helpful!

[@TheSundaeDrive]

No problem! Glad it helped.

[@tomcunningham2063]

Thanks for doing the video on how to change the plugs. Just got done with my 14 Sierra today. One trick I found on number 8 was to put a u-joint on the spark plug socket, then use a 4" extension. I was able to hold it straight enough against the firewall that it came out pretty easy. Most of them were easy to break loose (even though this was the first change at 147,xxx miles) and then unscrew by hand using an assortment of extensions. The hardest one for me was actual #5 on the drivers side because of the steering column being in the way. Might have had something to do with only having a 2" and 4" extension. I think an 8" wobble extension would have made that one easier to break loose and unscrew..

[@TheSundaeDrive]

Glad the video was helpful! The right size extensions definitely make the job a lot easier

[@wittelarry1]

I would use anti seize on the threads

[@TheSundaeDrive]

It's pretty controversial but ngk says never to use antisieze. They have a write up about it.

[@ahill7099]

I've twice removed them normally not throught the wheel well at all...not that difficult and all that trim is a huge waste of time

[@HTX-713_]

Do you know the part number for the AC delco spark plug wire number

[@warrenwallace2]

I've been noticing several companies selling a ac Delco tune up kit that has the plugs wires and coils all together so should we be changing all together coils wires and plugs. The kit runs 290 dollars for everything. For 2018 gmc Sierra 1500 5.3 ecotec3

[@excatholicatheist]

F'ing engineers. How ridiculous to have to remove the wheel to change the plugs

[@camarokurt]

When I pulled the boot and that whole heat shield with spring came out, I was like OH, S#!T!!

[@anthonycostill8654]

Do you think its ok to change the plugs at 75k miles? I got a 2018 and it has a little shakiness to it

[@KG-kt4sr]

Excellent video. Removing the heat shield for the number 8 gives you better clearance. To me there was more of a issue on the number 5 plug which is behind the steering linkage. Take your time and it’s a really straight forward job!!!
