- I had a vehicle in the shop it was a 2016 Chevy Impala but this information is the same for the 2014 to 2019 Chevy impala with the 3.6 v6 . we’re gonna show you how to change the spark plugs. More importantly we’re gonna show you how to remove the intake successfully without breaking anything and give you some tips and tricks on the installation I’m not gonna show you the installation because the engine that I’m working on is actually Hydro locked and I’m taking the spark plugs out to get the water out of the inside of the engine. but I do put up pictures of what spark plugs look like and what it means when they look different. Hopefully the video was helpful and if it was please turn on one of my Sweet playlist turn the volume down and let my mouth run!!!

Just did my 2019! Easy as 1, 2, 3! Thanks!
Thanks for sharing! I'll be damned to unscrew, unclip, push and pull, plug , snap, unsnap. nothing!! That is hella work!😮
Great walked through, helped me with my 2015 Impala
VERY HELPFUL VIDEO, THE WAY THEY SHOULD BE.
I'll pay my mechanic, change oil and air filter too......I work 70 hrs a week...I'll go to Applebee's and car will be fixed when I get back
Great video....
Thats what I went to dealer for today oil change, spark plugs replacement and air plus cabin filter replacement.
V6 pain to work on . Disaster
More informative than other videos. 2008 is definitely different.
Ya'll are just lazy
Great video thank you. Going to change my plugs next week.
This video help me out a lot thanks
Thank you very much now I’m not ask scared taking things apart I can’t see. Bless you 🙏
first video i saw that was very educational
At least 5 different connectors that I had no idea how to pry open without breaking TY!
😂😂😂
Thank you for showing the 3:56 part. That little tab had me about ready to go lose my mind.
You help me out a lot. I love to do things by myself.
Thanks broham i just needed to see it
A ducks quack doesn’t echo........... and no one knows why ☝🏽 great video and great facts. You are worthy my friend
Omg you are funny .. thank you for a great video of information.. I’m still laughing about smells like grandma’s house SHE WAS NASTY 🤣😂😂😂
Very Helpful, Thanks.
Anytime 😎
One note, have an 8inch socket extension for the back plugs. Just completed this an hour ago and the 10in was a little tricky to use on the back 3
Explain am not trying waste all that time lol
That last tube you took off of the intake at around 8:00 minutes. Does anyone know what that is called? Hard plastic snapped on mine, and I can't find it in the GM parts breakdown
You’re the man!
I had to look quickly when somebody says something nice lol I’m just kidding people do it all the time but they also say terrible things to it I’m glad you had a good experience and welcome to the channel thank you so much for the kind words
Went to take my engine cover off and noticed that it was a security bit that was needed for that 10mm screw. If you want to replace it, the measurements are M6-1.00 x 35mm for a suitable substitute.
Yes of course they are you can replace any fastener that you want and because it’s not around a moving component it won’t hurt to change it to a different type of head
Lmao a “security” bit 😂. It’s called a torx screw smh
@@scott4172 idk why you are saying smh on a comment I made over a year ago. It wasn't mentioned in this video and I left my comment for anyone who did not know. I had to go and get the bit from a mechanic that I knew and that's what he called it. My maintenance background comes from planes and not cars so don't shoot the messenger.
@@SleepyTucker it doesn’t matter dude.
Thank you I was getting so irritated your video saved the day.
while you are doing the plugs it's a good time to clean the mass air flow sensor and the throttle body. Just be very careful not to touch the mass air flow sensor, just spray it. The easiest way to clean the throttle body is to remove it, which is also easy, and you can get to the back of the butterfly which will be fairly dirty. When cleaning the throttle body, use throttle body cleaner, and don't move the butterfly around. These simple things will keep your car running and idling without codes showing up. Maybe The Clay Way has a video on one or both of those!
So I broke that last connector do you know name of that part?
Thanks for this . do u happen to know the torque specs for the manifold?
I don’t know them off the top of my head Brianna but they’re probably not any more than 25 foot pounds if that so just palm your quarter inch ratchet and snuck the bolts down you will be just fine
I broke one of the small tabs securing the brake booster line connector on the intake cover, do I have to get a whole new intake cover to fix this or is there a part I can order?
You could drill it and screw a nipple in it .
Yeah.... I’ll be having a mechanic do this lol
😉 well at least you will know what they go through. I don’t know if this is true or not but I would assume in your position it actually makes you feel better to know what they’re going to do then just have them tell you “yeah bud that’s two or $300” and then you’re like for some spark plugs WTF!! But now you know
just came in from doing this. I have the tools,, the garage, and a compressor. All toll it took me an hr to do the whole job. Piece of cake, But thanks to this Video, I knew what to expect, and that made it easier. Thanks
Haha foreal I don’t have the tools for this
I did this last night it was so easy anyone can do it
My exact thought
Very helpful! What is the name of the last vacuum hose you pulled off @8:14?
I can't remember exactly but it's either the evap hose or the brake booster hose. Hope fhat helps!
Hey do you recommend changing out the coil packs with changing the spark plugs? TRQ has a coil pack and spark plug tune up kit. Idk thought about changing just the plugs.
It’s not necessary coils generally have a long life if you can afford it , it doesn’t hurt, just keep in mind that nickels and dimes add up to dollars. It’s always best not to waste unnecessary money. That’s just my opinion obviously
By the way you’re absolutely right united we stand divided we fall!!!!! Divide and conquer seems to be the way of things nowadays. It’s really sad.
I remember growing up and my parents going “this is the end of the world as we know it”
I truly believe that now.
God bless welcome to the channel we’re happy to have a brother hopefully that advice as helpful
@@sharpcarco thank you Clay your awesome stay safe and god bless you too.
Clay, have you ever pulled the injectors on a 3.6 LFX? If so, how difficult are they to remove? I understand you have to remove the fuel rail first, but may possibly need a puller to get each injector out of its bore.
Reason I'm asking is I have a '12 Impala with the LFX and every time it snows out (and ONLY then) the car starts misfiring and spits out a P0276 code. Apparently there's a TSB for this engine stating the injector harness rubs up against the transmission and can cause a short to ground, triggering the P0276 (amongst other codes pertaining to the different injectors.) The injector harness is run beneath the bodies of the fuel injectors, so in order to get the harness out, you need to remove the whole bank of injectors. Also some of the fuel rail tubing is not reusable and must be replaced when you remove the rail.
www.boschautoparts.com/en/bosch-for-gdi/gm-3.6l-buick
I went ahead and purchased a new set of injectors instead of purchasing the seals and the seal installation kit (replacing those seals sounds like a complete pain in the ass!!) Also the required non-reusable fuel lines, fuel pressure sensor, and a used front bank harness. I'm going to pull the intake and clean the carbon off the backs of the intake valves, then swap out all 6 injectors and front harness (and inspect the rest of the harness which hopefully is exposed when the intake is off.)
After that long-winded tirade, I thought I'd mention that on the W-Body Impala/Limited LFX's, you can access the rear coils and spark plugs without removing the upper intake...
Thanks for your time!!
Hey wagons sorry for not getting back to you sooner it’s been super busy the last two days no I’ve never remove the injectors out of these but I can’t imagine that they’re much different. Different than the other ones and yes they are a pain in the ass to get out they do pull straight out once you remove the keeper. I’ll take a look at this one tomorrow that I have in the shop and see what I can see
I just looked down at the injectors on this engine that I’m working on and I think you’re correct you pretty much have to pull them out I remember the last time I had to pull these injectors out of the cylinder head it was a real pain in the ass. I did however reuse all the fuel lines etc. etc. they are metal fuel lines I don’t know why they would have to be replaced. The injectors look like they’re extremely easy to Once you take the intake off
@@sharpcarco Thanks for taking the time to look at that 3.6, I appreciate the insight. I'm taking a week off of work to tinker with those injectors so I'm not in a mad rush to get everything done right!!
@@sharpcarco by any chance can u do a video on how to remove and clean the throttle body on 2019 impala lt please
You the best
You are too !!
Great video man ... but my question is should re-use the intake manifold gasket after change the spark plug?
Well when considering if I’m going to reuse a gasket or not I take a look at it if it’s flat I don’t reuse it if I do reuse it I put dielectric grease on it (Both sides) I reuse them all the time personally but I can’t see yours so I can’t tell you I mostly reuse them because I’m extremely cheap
@@sharpcarco good evening
I replaced spark plugs for a 2017 Impala
And now I increased the noise from the purge valve...
What is this due to?
The mechanic did not put silicone in the gasket, he said the gasket remained intact
Is the noise in the purge valve an air leak?
Thank you
what is the right gap for spark plugs for 2016 chevy impala v6?
I don’t know that off the top of my head but there’s a white sticker underneath the hood that will give you the gap but you are supposed to be using platinum plugs original to the vehicle and they should not need to be gapped ....
AC Delco plugs are already set to the correct gap - .040”.
Hey I know this is a shot in the dark. But I accidentally broke the only hose you didn't disconnect. The one on 6:46. Do you happen to know how to fix that? I got the spark plugs put in but now dealing with this. :(
Should I also replace the plug wires and coil packs? 92K miles and first tune up. What other things do I need to do for a tune up?
Well, there’s no wires to replace
And I don’t recommend replacing the coils because once you get this job done or you start doing it, you’re gonna realize how simple it is it’s not complicated nor is it difficult to replace coils even though you do have to take up the intake to do the back ones you’re gonna find that really removing the Intakes like a 30 minute job at most So I would just recommend replacing the spark plugs with OEM other than that, leave everything else alone
This foo said the spark plugs smell like nasty booty & his granny house😂😂😂 Thanks 4 the help tho.
Thank you sir
Hey which one is cylinder 3?
video for 2013? is it this hard as well?
do you have to torque the spark plugs when installing them back?
thank you
There is a torque rating for everything but tightening up spark plugs I’ve never torqued them down. You just snuck them up you do not over tighten them. I’ve never looked up the torque rating but I would have to guess it’s like 20 inch pounds not foot pounds when they get tight just turn them an eighth of a turn more than you should be good I hope that helps
Yes it helped Thank you man your videos was very helpful gonna try changing mine
I put just a small touch of Anti-sieze on ea plug as they went back in, and did an 1/8 after contact. Snug,, Not cranked down, unless you don't want to take them out next time.
What was the problem with this impala
Mine is shaking while idling and sometimes
Shudders while driving
That is the same reason that I replaced this one you could possibly have a bad coil as well so check into that before you replace the spark plugs by using the scanner and seeing which cylinder is misfiring then switching the coil from one cylinder to another cylinder and if the misfire changes from one cylinder to another cylinder the coil is defective if not you need new spark plugs
Thank you:)
Can you add a cold air intake to replace the original one by any chance?
Go to my10thgenimpala on facebook. Theres a guy named jess connors who sells custom cold air intakes. He also does tunes.
@R Skip yea I agree I have a drop in filter and it works pretty well. I really don't see how a intake would change much especially bc the stock intake is already in a good spot and getting cold air anyway.
@R Skip Yea i've heard e-85 sucks with the LFX. I'm defiently getting a tune but thats probably it. I don't think many other mods will do much.
I got a p0107 code after doing this and my car has a ruff idle how can I fix it ?
You have a vacuum line off
Is there a way to do this without removing the intake? Like using flexible extensions etc?
There’s many people that says that you can but to be honest with you I just did one of these and It only took me about seven minutes to takeoff so I would imagine even if you’re kind of inexperienced it might take you 10 or 15 it is extremely simple to take off and I’m certain you can do it I know it seems like a huge obstacle when you look at it but once you actually take it off you’ll be pleasantly surprised and very happy with the outcome
And I totally agree with you on the divided we fail part.
Julius Caesar in Napoleon Bonaparte. Greatest battle plan surrounded divide and conquer
@@sharpcarco yea it’s intimidating with all the wires, hardware , clips lol thank you
@@sharpcarco also dhow do you know if I need to replace the intake manifold gasket. Chevy said during the quote that they may just replace the gasket while they’re there. Extra $$ money of course.
Have a 2018 Chevrolet impala premier with the Original spark plugs 70,000 miles, when should I change them?
80,000 to 100,000 miles you could do they now it won’t hurt, they are designed to go a 100,000 mile im assuming the owner’s manual will tell you for sure , I recommend using OEM plugs , I don’t often recommend OEM anything (most of the time won’t last any longer for the extra money ) because must everthing is only made in a few factories around the world , but OEM plugs already last 100,000 miles, quite a few times I tried others and they don’t last as long as OEM
@@sharpcarco Thank you so much for your input, I think I'm a do it around 85,000 miles, my owner manual say do it at 97,000 miles. Just trying stay on top of Maintaince Thanks again
@@sharpcarco does dealer add the spark plugs as they were or add iridium
good evening
I replaced spark plugs for a 2017 Impala
And now I have increased noise from the purge valve...
What is this due to?
The mechanic did not put silicone in the gasket, he said that the gasket remains intact
Is the noise in the purge valve an air leak?
Spray the intake with carb cleaner or brake cleaner while the engine is running, and if the engine idle increases, then you have a leak if it doesn’t, it’s OK I’ve had them purge solenoid’s make that TikTok tick-tock tick-tock tick noise in the past
@@sharpcarco first of all thank you very much
for the answer.
I did not understand about the noise of the purge valve
Why did he start doing tik tok at high volume?
And where to spray material? The manifold is closed from the bottom
Basically, you spray the stuff anywhere that something meets together like your intake around hoses and stuff…. All over the top of the engine. It will evaporate the only reason it would ignite is, if there is a spark, jumping somewhere other than that in a couple of hours it’s going to evaporate or suck it into the engine keep a fire extinguisher handy put it out immediately. it shouldn’t hurt anything even if it did catch on fire but that’s only happened to me one time out of a couple 1000 the thousand times I’ve done this and that’s because the guy thought he had a vacuum leak and he actually had a broken spark plug wire you do not have spark plug wires, so there should not be an issue.
@@sharpcarco Could the ticking noise of the purge valve be caused by a leak?
I think this video will show you how to perform that procedure
I was going to change the plugs in the wife’s Acadia, but after seeing this I’m just going to buy her a new car, and it won’t be a sideways v6 next time.
Were you able to get this engine back running?
No
You don't have to take all that apart to get to rear plugs, all you need to do is remove cover, then air filter box and line that goes over intake, then 6 bolts that hold intake in and just lift it just enough to the side so you can get to plugs.
I changed plugs on my 2017 Impala 3.6...
4 of the plugs are accessible without removing the plenum.
The front 3 and the driver's side rear plug can be done that way.
The center and left rear plugs cannot be accessed without loosening the plenum.
I did not need to unplug the coil wire connections....I took out the 10mm coil bolt and simply pulled each coil out with wire attached and moved them out of the way ....I did one at a time, replaced plugs one at a time, reinstalling the coil before moving on to the next coil and plug.
I went to AutoZone and bought a 5/8" magnetic 3/8 drive socket which was connected to a 10" 3/8 drive swivel socket.
This made it simple to remove and install the plugs as the magnet held the plug in the socket during removal and install.
I also only removed only enough connections to be able to unbolt the plenum and swing it just far enough to get to the last two plugs.
I did not need to remove the plenum entirely from the car.
I had the whole job done in about an hour to hour and a half.
Torque for lower gasquet bolts pls
There’s a long reason why I don’t put that in there Gilbert.
Mostly because I got tired of arguing with people about what I said in my video and what Google says. Hopefully it doesn’t make you hate me . Bolt torque goes from the thread pitch and thread size. It’s a standard equation. If I was the gas it’s probably about 18 foot pounds
Glad I have a 4 banger.
Got a 14 impala v6. Getting ready for that 97k plug change. Is $700 a good charge to get this done?
No Way too much money…… do it yourself think about it this way…… if you do it yourself you just made $700 Unless you make more than $700 for four hours worth of your time than I would say there’s value
@@sharpcarco 4 HOURS?Just did the whole job in 35 minutes without pulling the intake
@The Clay Way how u do it without taking out the intake? Imma do mine this weekend and I'll def try it without taking it out 1st
No way to do that and really not worth it even if there was it will constantly be in the way. I know it seems like a difficult task to take the intake off but it’s no different than changing a set of brake pads..
Maybe on a four-cylinder..
Damn that's a lot
Not really it only seems like it once you actually start doing it it becomes very simple
Isn't that the same engine as the v6 camaro
To my understanding it is
Lfx on the camaro is much easier to change the plugs
👍🏼👍🏼😊🖖🏽
Don't use " Scotch bright" anywhere near your engine
After watching this.... I'm just going to a mechanic or changing the 5 I can get to without removing the intake
Dealer wants $495 for this job!
Well if you end up doing it yourself consider yourself getting paid about $400 to do it!!!!
Welcome to the channel we’re happy to have you
@@sharpcarco What torque do you use for the intake manifold if I can ask?
It’s physically impossible for a pig to look up lol
Folks if you do all that PLEASE replace the spark plugs while you got everything off... espn if there is water damage. This guy is tripping
How much horsepower does this add if any?
This car uses platinum spark plugs, if u change them to iridium there will be a slight almost unnoticeable difference unless the car is tuned
Moustafa Dawi thanks for the reply. What can i do to give this car more power? I jus got mine a week ago 😂
Chevy dealer 300$ is that reasonable
Well if you don’t want to get paid $300 to do it yourself it sounds fair enough I guess
You really don’t have to take the cover off
Explain
He’s probably explaining that you can get to the back spark plugs without taking the intake off. But I don’t know how I would’ve possibly showed anything without taking the intake off.
And it was a long time ago that I did this procedure so I can’t tell you if you can change them without taking the intake off but I can tell you taking the intake off is very simple. But to each their own I’m sure there’s ways of doing things around other things that are in your way.
Personally I found with my Small amount of time repairing automobiles that it’s generally much easier just to take whatever is affecting your line of visibility, and accessibility that makes it much simpler to perform a procedure just get it out of your way. you will spend more time trying to work around it then what it would to just get it out of your way. With my little bit of experience on the subject. ……. I mean I only have about 30 years of experience I guess I need to wait another 20 before I start telling people how to do things
My ac quit
I sure hope my plugs don't smell like nasty booty. 😂 It's important to use the correct plugs. Use what Chevy recommends. Dont go cheap, and get them from a reputable source. There's some fake plugs out there, so only go to a reputable parts store, or GM parts
Yeah, I said this in the video. I’m sure you had turned it off by then….
Seemed to be an OK video, but lost me with the useless tid bits at the bottom of the screen.
VERY distracting.
JMHO.
Oh that’s a problem with you tube have to be creative.... Most people go to watch video. They
Skip through to the part of the video that you’re looking for never thinking about the person that produced it or made it and a 30 minute job turns into two days worth of work and when people skip videos it hurts the channel that made the video that is trying to help them they don’t understand that viewer retention is a big part of the algorithm. If the guy didn’t help you it probably doesn’t matter but if the guy did help you then it makes a humongous impact on the channel. Then the channel literally make nothing so I differentiated my channel not only with positive speech , And empowerment ,with distractions with the hopes that I will gather more view time,
From what I can tell some people love it some people hate it. And I enjoy being able to tell people the useless facts In Otherwise possibly awkward social situations ........
Some of them are very interesting and quite a few people actually look them up to double check me
it’s not on every video but it’s on some of them.
I Appreciate your input thank you very much have a great day and God bless
Take it to the dealer its only $9,000.00 what a dam joke remove half the motor to replace the plugs.
This looks like a lot of work. 😒
No not really, just give it a try take your time you’ll be done within an hour or two even if you’ve never done it before.
Keep in mind that if anybody else can do it you can do it to
Quick question. I have a 2016 Impala ltz. Lately I will be at stop light and it just shuts off. I put it into park and push start and it starts back up. Any idea what that might be? And have you heard of any other Impalas doing that?
Well that’s probably not just a symptom of an impala. They put this particular engine in several makes and models and they are notoriously not good engines.
Unfortunately I wouldn’t be able to help you with that because there’s a lot of different things that could possibly be.
But I think if you take it over to a shop and you pay them the hundred dollars it will cost to have them look at it it’s probably well worth it I would recommend starting with a tuneup if you’re over 90,000 miles it certainly will help and won’t be something un necessary to do.
You had us take apart half of the engine bay, just to not help us put it back together? Woooow
Forget the part where it’s a free video on the Internet helping you save hundreds of dollars from paying somebody else to do it for you I guess……. Couldn’t you just follow the steps backwards……..
@@sharpcarco Lol im sorry. I would just think that since you had to put it back together as well, you would complete the process. Youre right though, thank you
You’re kidding right?…….. have you ever made a TH-cam video? I don’t know how long it would take you but even making this video puts an extra 5 to 6 hours of just labor into doing the job then if you consider another 2 to 3 hours in editing that would make it a two day job.
For changing spark plugs that’s why you don’t often see people making videos about reinstalling something after they made a video of taking something apart.
No I don’t make perfect videos but I certainly try to make them the best I can and the amount of time that goes into even a short video like this one generally is a day or two.
I understand you don’t know that but if you ever wondered why that’s the reason why.
You must be joking,just follow the steps in reverse
You probably shouldn't work on your own car if you need your hands held like that
