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

[@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

[@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

[@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

[@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.

[@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.

[@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👍🏻

[@miscellaneous037]

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

[@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

[@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

[@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

[@shawnhodges4]

1st time ever changing spark plugs on a Silverado. I started by attacking them from the engine bay like I've always done for my muscle cars; wow, what a pain! Discovering this video made a world of difference on how to properly access the spark plugs through the wheel well. They are a straight shot in for easy access and proper torquing.

[@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!

[@farmingfishingfamilyontari2814]

I’ve got 95000 kms. I drive it easy but we live on gravel. Any of you guys that can avoid it count your blessings. This truck in video is so clean bravo.

[@americanpatriot2999]

That was outstanding. Auto mechanics is getting to be a lost art. The younger generation doesnt seem to be interested in doing that hard work. I studied auto mechanics in high school for all four years. Ben Beam and Tom Stoddart, may you rest in peace.

[@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

[@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

[@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!

[@clodhopper1876]

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

[@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!

[@paulpierce5921]

He did a great job explaining how to change the plugs. I only have one criticism and that is, he didn't put antisieze on the plug threads. My experience has always been use antisieze with plugs in an aluminum cylinder head.

[@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

[@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!

[@luisagron5754]

I normally don’t write comments, but I have to say if you are a Silverado owner you should subscribe to this KZbin channel. I just replaced the spark plugs in my Silverado and it was so easy after watching this video, even my friend that’s a mechanic was surprised of how easy I replaced the spark #8. Thanks for the great video!!

[@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.

[@TheSundaeDrive]

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

[@arthurgarza447]

Thanks for the video. Started to take on replacing the plugs from the top, before finding your video. I removed 7 spark plugs from the top, without removing the wheels. It's mostly by feel, and doing it blind without being able to see most plugs. Had to remove the wheel and wheel well on the difficult 8th one.

[@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.

[@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!!!

[@nelson587]

Great video on making it easy changing my plugs on my 2015 Sierra with 104,000 mile.. Only thing was would have liked for you to show your older plugs compared to the newer ones ...

[@TheSundaeDrive]

Good call!

[@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!

[@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

[@dantadysak5485]

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.

[@TheSundaeDrive]

I have found that from the top on the driver side is easier but definitely prefer the bottom for the passenger side

[@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.

[@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

[@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

[@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

This video helped me out a ton on changing mine. Thank you for posting it and giving me the confidence to give it a shot myself.

[@randykuik2070]

Thanks, worked out just like you said. Including how to do #8 with a 1" extension. Took me about 2 1/2 hours. It took longer to take tires and fender liners out than the plugs, but believe a lot easier job through the tire wells.

[@trifcake]

Cylinder 8 is actually quick if you have the right tools. I just got finished changing it with a deep socket 5/8, universal joint on a flex head ratchet. Slid right in, broke free and replaced in under a minute.

[@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.

[@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 🤷🏼‍♂️🙏

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.

[@barrypowell829]

Good video for removing the spark plugs. I’d never would have thought of removing the inner fender well cover. Thanks

I really don't understand why anyone says this is that hard of a job. I just did them all without taking anything off from the top took me an hour. Even the "8th" one. Anyways good video very informative!

[@kackendall]

Great video. There couldn't be a more perfect example on how change these plugs. Thank you!

[@TheSundaeDrive]

Glad it helped!

[@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

[@SaSiSamurai]

Worked perfectly for me thank you very much! I ended up doing #5 from above because the steering wheel column was in the way. This was a bit easier for me. And for #8 I didn’t have a 1” extension but it worked quite well with the spark Plug ratchet I had. I would recommend getting a flex ratchet.

After having done it several times, Ive found that the passenger side is easier from below and the driver side is easier from the top. Checking the gap is very important and I should have mentioned that in the video.

[@BlueZ06Kevin]

thank you for this video. I started without removing the wheel but quickly changed direction and it was do easy. one BIG lesson though is to make sure wire #5 is not installed around the steering column. sounds simple but from the underside it's easy to get wrong. I broke the wire and had to replace it.

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

[@kimberlymiller7316]

Excellent video, thanks. I used long extensions and swivel for #8. Went right along the rear of the wheel wheel (behind fuel line?) and just under the horizontal section of a/c condensate drain. Still, it's a challenge to see that plug or get a hand in to guide the floppy swivel. I spent more time cleaning out the body panel than I did changing the plugs-seriously! (you can't do that from the top). The debris that you show at the beginning of the video becomes a moisture trap and acidic over time (especially pine needles). And don't forget road salt if you've made a trip through the rust belt. Left uncleaned, body rust will start from the inside and make an appearance just behind the mud flaps-too late to clean anything then. The problem is that leaves, nuts, needles etc. fall in from the ends of the windshield trim and have nowhere to exit. I used a wire with a slight barb to work leaves, sticks etc. out though the thin opening on the inside-bottom of the panel while I was spraying water full-force into the top and side. We'll see what it looks like 100k miles from now.

[@stevevalencia2450]

Very informative, I would have never thought you have to take the inner fender wells out! But now I can save some bucks! Thanks

[@TheSundaeDrive]

Awesome! Glad it helped!

[@scotthotz8844]

Great video. The Gear Wrench spark plug socket-swivel-extension worked nicely. Used a few other 3/8" extensions depending on the position. Driver's side from top was no problem. Passenger side definitely need to pull the wheel and liner. Michigan dirt roads hiding the #15 Torx was the biggest challenge. Was able to torque #8 using the GearWrench socket and extension.

[@mikec3454]

Great video, this is going to come in handy next year when I change them on my 2018 Silverado. Only thing I would add is putting some anti-seize on your plugs to make it a bit easier to get out next time.

[@TheSundaeDrive]

Thanks! You need to be very careful doing that as it can mess with the torque values and cause you to snap off the plugs.

[@vtexcrsn]

You were right, much easier just to take the tires off! And, I cleaned out the debris caught up in the front fender seams like you found!

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

[@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

[@tdrums9]

Loved the video man, doing plugs wires and coils tomorrow. Just a heads up, using extensions on a torque changes the torque accuracy significantly.

[@TheSundaeDrive]

glad the video helped! very important to keep extensions to a minimum for sure!

[@sodomyishthenewblack]

This video slaps. thank you, for the tips for number 8. so much better than laying over top of engine.

[@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!

[@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

[@stevenstair1068]

I just done my 2015 done mine threw the top with out removing tires and fender liner,, 2.5 hours and it was done, now that's plugs, wires, and coils ,and all belts and tentioner, 8th was alittle tough but if your mechanical inclined you will be fine..

[@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 Yes,it can be done over the top,but you have to be young and have the special tools.Its easier to take the wheel off and splash guard if your old like me at 70.I like to see what I'm working on

Thanks for video. Is this same exact process for 2017 suburban?

[@kevinkulikosky2119]

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

[@curtisfranklin5242]

Good video, thanks for that. Why pull all 4 plugs at a time? To keep the system clean, pull and replace individually. Not likely to happen given the orientation of the plugs, but why take the chance of something getting in?

[@TheSundaeDrive]

That's definitely the safest way to do it

[@cehuddl]

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

[@TheSundaeDrive]

Glad it helped!

This guy needs more subs.. Always great vids keep it up man.

[@TheSundaeDrive]

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

I once replaced the plugs on a transverse mounted V6 engine. The ones on the back side were incredibly difficult to get to. If it had been anymore difficult that it was, I couldn't have done it.

[@brandoncantrell3317]

Never thought to remove the inner fender. Great video

[@TheSundaeDrive]

Thanks!

Great videos Cliff! You have helped me a ton with my 2014 Silverado maintenance!

Awesome! Glad it helped!!

[@dantheisen1227]

I have to do this soon and will be using this video as a reference nicely done!

[@TheSundaeDrive]

Glad to help! I do recommend driver side from top tho having done it more now

[@garfylunds7301]

Excellent vid and thanks for the effort and for having the camera on a tripod and such. It is so much easier to follow along. #8..what a pain and you nailed it! ... But taking the fender well covers off is the trick. I have no issue with doing that if it makes for me not having to contort over the fender into the engine compartment!

[@TheSundaeDrive]

Hope it helps you! I've found the driver side is actually easier from the top but the passenger side through the fenderwell for sure.

[@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.

[@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.

[@danielgomez8187]

I changed the spark plugs on my 2015 without removing all this extra stuff, 7 out 8 are easy pretty simple job

Can be done from the top for sure. I prefer not laying out in the engine bay for us average height people lol

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 ?

[@DCM1234epic]

My 2014 calls for iridium. They came from the factory with iridium plugs Mine is the 6.0 engine.

[@mtk2fitness208]

Just changed mines. Driver side from the top took about an hour. Passenger took less but I didn't even change the 8. I was done after the seven.

[@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.

[@crbrepairmotorcycles6608]

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

[@TheMrmmkkpro]

Cool , than K s for the detailed info. My 15 6.2 is ready for plugs. After doing my 1990 ZR-1 , this looks easier. 👍👍🏁🏁

[@TheSundaeDrive]

Best of luck! Driver side is easier from the top I have found tho

[@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

Got it done on my 2015 GMC Yukon Denali. Thanks for the good video!

[@TheSundaeDrive]

Glad it helped!

[@raygaither9369]

I wish I had watched this video before I started on mine (2015 Yukon XL Denali). If I had taken the fender well off on the passenger side to begin with I would have saved a lot of time and aggravation.

[@TheSundaeDrive]

Atleast you know for next time!

[@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.

[@TheCaleb0209]

Do you have a video on changing the ignition coil?

[@TheSundaeDrive]

We do not at this time. Ignition coils generally last a pretty long time so haven't needed to replace them yet.

[@nathanmedema5458]

Surprised you did not mention to put anti-sieze on the plug threads before installing.... will help in the future in getting them off next time!

[@TheSundaeDrive]

This is a hotly debated issue and there have been a lot of comments on this ngk recommends against it. If you choose to use some, use very very little as it messes with the torque. Most newer plugs have a coating to protect them from fusing.

[@ND-jv4hg]

Great video. I just checked and it doesn't look like changing them from the top through the hood would be that difficult, rather than through the wheel well. Is there something I'm not seeing where it's just not practical to attempt this? That 8th. one still looks like the toughest.

[@TheSundaeDrive]

After having done this a few times I think the driver side is easier from the top and passenger side is easier from the bottom. I always do the passenger side from the bottom because it makes it so easy to do

[@ND-jv4hg]

@@TheSundaeDrive I mostly agree. I actually went ahead and changed them all from the top. I found the passenger side slightly more difficult, and I wonder if it had to do with being right handed. The most difficulty in doing it this way was reaching over, I had to stand on a stool to reach them, and I'm almost 6'. Anyway, the 8th was still a bear but I got it. Your video gave me the encouragement.

[@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

[@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?
