How To Replace Spark Plugs Like A Professional

[@vickenkaragozian2041]

Great video guys. I worked for LAPD for 21 years and i torqued all suspension bolts, nuts, spark plugs and of course all brake caliper bolts and even bleeder screws. You'd be surprised how many people didn't even torque the lug nuts or the intake manifold bolts. I have all the torque wrenches, quarter drive, 3/8 drive and half inch. Plus i marked every bolts to make sure that i torqued them. Thanks for reminding all technicians to be professional at their job.

[@johnweiland9389]

Every time I get brake pads replaced. I have to get new rotors, (because nobody uses a torque wrench on lug nuts).

[@bbstacker70]

I've been a shade tree for 60 years or so. Before I do anything, I always blow compressed air into the depression where the plug resides. Then I loosen the plugs and blow them again. If, like most, the car has a COP, I blow off all around the COP, then remove it. Only takes a minute or so, and keeps sand, small pebbles and the like out of the combustion chamber. Please take this as I wrote it...a hint, not a knock on you. You have forgotten more than I ever knew. Great videos and kindness to spare.

[@clampingdiode]

I've been in the grind professionally about 40 years. Love your videos. The most impressive thing about this video is the fender covers. ...and that dog. :)

[@Mr2004MCSS]

I have been changing sparkplugs for over 40 years and have never used anti-seize on the threads. I was told years ago that the addition of anti-seize to the threads will mess with the torque specs if you use a torque wrench to torque them down. I have read that some manufacturers do not recommend using it, but I can't remember which ones off the top of my head. I have always used dielectric grease in the boots though. Great video as usual.

[@fascistpedant758]

I agree, but a drop of light silicone spray lube doesn't hurt. With dry threads, the specified torque doesn't always even crush the seal.

[@DieselDog358]

I've heard that same thing when I was at the factories main engine training center.

[@abovetherimrob891]

Cast iron heads and aluminum heads are vastly different. Always use anti-seize on aluminum heads.

[@Mr2004MCSS]

@@abovetherimrob891 I have owned a car with aluminum heads since 2006 and have never used anti-seize on the plugs and never had issues removing them when replacing plugs.

[@nickr5658]

Always use antiseaze unless the mfg says not too. It helps heat transfer and will extend the life of the plug aswell as helps ensure proper torque.

[@steveb319]

Great video. Thanks. I’ve seen the debate over use of anti-seize. I’m a DIY person who uses it with no issues. I’m sure they’ll be comments about what can go wrong but those people never seem to show any videos about the “wrongs” happening but just prefer to comment and troll on other people’s videos.

[@carlosphlegm7001]

I use a spare tire to stand on all the time, so I really liked seeing you do that the same. Particularly in your spotless, extremely well equipped shop that I've admired through so many videos. For the record, I'm 5'8" and work on a lot of 4X4 pickups.

[@IUnknownIDispatch]

Great advice! In addition to your process, I will take a shop vac or compressed air and clean out any debris in the plug recess prior to removing the spark plug. Yes, it's overkill, but you may be surprised what can get in that recess.

[@bandett4]

This would be a great video in an apprentice guide play list for young people just getting started. It's been my experience that a lot of older techs will tell an up and comer to do somethingbut they skimp out on the why it it needs to be done a certain way. Great videos

[@JJJobson]

I always spray brake clean followed by air after removing boots. Then remove the spark plugs. Thanks for the videos as I do not work on vehicles for a living. I just thirst for knowledge. Love the diag videos as well. ❤

[@anthonyiannone7618]

A few additional things to consider , #1 Make sure the springs are still inside the boots when your putting the coils back on , sometimes they fall out without you even realizing it. #2 Look inside and clean out the wells before removing the plugs. Many times the wells are filled with oil / debris. #3 inspect the boots for any signs of arcing. Even a pinhole is going to be a problem.

[@map7463]

Why not replace the rubber boots so you don't have an issue before the spark plugs require changing again. With some V6s the intake manifold has to be removed to change the spark plugs. It would suck to have to do that work again.

[@joecool169]

I would have never pulled those plugs out without blowing out the well, cracking the plug lose and then blowing the well out a second time.

[@fascistpedant758]

The electrical connectors unlock more easily if you push the connector in further to relieve pressure on the lock tab before attempting to release it. I recommend blowing the area around the plug out with compressed air after loosening the plug a couple of turns to prevent any debris from falling into the cylinder. I used to use anti-seize on aluminum heads when they first became more common ~40 years ago and it was common for plugs to seize in the heads. Probably different aluminum alloys and/or coatings on plugs seem to have solved the seizing problem a long time ago. I can't remember the last time I wasn't able to remove a plug without some sort of damage.

[@gjm3525]

With the air filter open like that, anything falling off the spark plugs or working area will sit on top of the air filter on the 'filtered side'. You then put the cover back on and it' straight into the engine. I'd have covered that. Really like your videos and learn a lot. Glad I found your channel, thanks.

[@DieselDog358]

As you can see, the lowly spark can generate alot of conversational opinion. We are all still apprentices after 45 years. Keep producing the videos. 👍

[@jptrainor]

If you want an active comment section, just make a spark plug video and take a side on the antiseize vs. no antiseize question. Guaranteed flack in coming. It doesn't matter what side you take. Just take one.

[@juancabral342]

Wow! The measuring. Never would have thought that pre gapped plugs could be wrong. Makes me want to check mine!

[@davewhite9794]

Nice video. I was taught 55 years ago to break all the plugs loose, replace plug wires, start the engine, and rev it a couple of times. This breaks the carbon built up at the end of the plug and combustion chamber. If you don't, there is a chance a piece of carbon that breaks loose can strike the spark plug electrode on start up. The carbon could close the gap, messing with proper spark. Before fully removing the plugs, use air pressure or vacuum to clean the area around the outside of the plug. Hope this helps.

You guys give such great instructions!! VERY helpful to us home mechanics trying to help friends as well as our own family save a bit of money at the shop. Please do a 5th gen Explorer (like 2013) with all wheel drive. When I had the dealer change my plugs they said "Well it's a transverse mounted engine so we have to take a LOT of stuff apart in order to reach the back 3 cylinders" and they charged me A LOT of money to do that. I paid up cuz I didn't have the tools nor the time to do it. BUT that's since changed and I would LOVE to do this myself some day. I would also love to see how y'all do it. Thanks for all you do to empower us DIYers!! Really appreciate your channel.

[@DieselDog358]

Perhaps it would be a good idea to wipe the porcelain portion of the spark plug with isopropyl to clean off the oils from your fingertips. Some manufacturers of spark ignited engines do recommend doing it. Great Video. 👍

[@bryans5339]

Great Comment!

[@fascistpedant758]

I just avoid touching the porcelain.

[@DieselDog358]

@fascistpedant758 How can you possibly know that you or others haven't touched the plugs along the way? The factory doesn't give the option of " if you or others haven't touched the porcelain, then you can skip ....". You need to wipe it down if you're going "to replace plugs the professional way." It is professional to wipe the plug as any beads of finger oil can cause flash over. I can send you pictures of what we have experienced in the lab.

[@garysgarage3669]

I'm really glad you talked about some (Ford) spark plugs that should be remove on a hot engine. Of course on a Ford truck, it will be the one in the back. That is the hardest to get to, that will break.

[@JOMaMa..]

[@abdul-kabiralegbe5660]

I think the reason the rear plugs are difficult to remove is that they're often skipped because of limited access.

[@john_dee1431]

Appreciate the content. Re: anti-seize, modern NGK and others are coming coated out of the box and warn that any form of anti-seize will change torque values. Not always the case but something to watch for.

[@JeredtheShy]

All I have to say down here is that yeah, plugs seem like one of the easiest jobs, and in many cases they are, but they're spooky, and mission-critical. I know a lot of the trucks have absolute nightmare plugs, many of the cars do, and even on "easy" inline 4 cylinders it's always a relief when they come out clean and don't bring the threads with them, and another relief when they snug down firm and don't keep spinning with the wrench.

Man, i love you guys. I've been seeing and watching your videos on fb, fb reels, and now YT for probably over a year now, and i love how honest and in-depth you are with your work. Im really glad i watched this particular video bc i have a 2016 Ram 1500 with the 5.7 hemi and i have never changed or replaced a single spark plug on the truck since i got it in 2018. It has 158k miles, and it's never had a misfire code appear in the system. I was really surprised to see yall doing this on a truck with 30k miles. I have one question about using the copper anti seize. What's the issue with the aluminum anti seize? I've always used the aluminum or grey antiseize for the plug threads. I didn't know there was an issue with using the aluminum kind.

[@midiman5045]

Good Tips Sherwood. i have always check the gap before installing the plugs.

A sprits of interior detailing spray on those connector clips helps a lot, lubricates them so they slide apart.

[@michaelsimon7414]

Thanks again for another great video, I learn from them all. I would like to add something to this video. In all cases before removing any spark plug blow into the cavity with an air nozzle to remove any oil or road debris that may be present. I have seen spark plug boots submerged in oil from a leaky valve cover gasket. This means more work is needed before finishing the job.

[@pgreenx]

1:15. Guy just wants to replace them and get paid….. 1:57 Guy jams whatever is available in 12:46 the can't be good.... 15:10 NGK SAYS NO ANTI SIEZE FOR THEIR PLUGS DIRECTLY ON THEIR WEBSITE 5 THINGS YOU SHOULD KNOW ABOUT SPARK PLUGS 1. Anti-seize NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Thread breakage can sometimes involve removing the cylinder head for repair. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.

[@483SGT]

But these aren't ngk

[@pgreenx]

@@483SGT they said they use ngk and they said always use anti seize and surely all premium plugs work the same way. this is old school tech stuff that never kept up with the times. Just like he taps the plug to gap it

[@andrewdobbs7000]

The brand doesn't matter. What's important is whether they are plated. Some brands are nickel plated. It they are plated, you don't use any anti-seize. If they are bare steel or black oxide, then you use anti-seize.@@483SGT

[@maxrx7]

Don’t drink milk because it’ll make you fart

[@OrificeJohnson]

Might be an edge case, but I drive a Honda Fit that uses NGK plugs and they recommend using anti seize on the threads in their service manual. The manual did update to call for 20ftlb instead of 13ftlb on the plugs though so I would wonder if calling for anti seize was the reason for them to increase the torque spec.

[@alexross8722]

Thanks for the tip about the combustion chamber cleaning and hot engine plug removal for stuck plugs. I tried to remove and inspect the plugs on my wife's 2019 Civic with now almost 200k miles on it, and they were (are) stuck so badly I gave up as I don't have the ability to install threaded inserts if I stripped out the aluminum head! I guess this job is going to be for the dealership. :(

[@scottykilmer3920]

Let me tell you sir, the best brand spark plug i have used is the brand Beru. This brand is known to have a very reliable spark for a long time! Second brand for me is the Ngk. Outside of these 2 brands, I've noticed power loss to my experiences. but I have also noticed that some cars only run well on the Oem spark plugs, and other than that sluggish.

[@israel9294]

I always use spark plugs from the dealer original only. Some want a different better long lasting brand but there is a downside to using these other brands that last longer. The longer your spark plugs stay in your engine the more likely they are to seize with the heat and corrosion over time.

[@spelunkerd]

Do manufacturers make the gap small so that as the plug ages the gap increases into the oem spec? I replaced plugs on a VW last year, and the OEM recommended new plugs had gaps that were all 0.2 mm too small out the box. I double checked it with two plug checkers, being sure not to damage the platinum coating. I used the exact brand specified by the dealer repair manual. After a little head scratching I decided to grab the neutral pole in a vice (on the sides so the platinum coating was not affected) and gently increase the gap, but I wondered if I might have been better to simply install them with a small gap....

[@jrock-xs9vp]

Thanks for your video. I've never used ant seize on spark plugs, but I see it because of the complexity of these new cars . Great advice about not using gun on them, coil bolts people have gone crazy using gun on everything on these cars .That makes sense about calibrating your elbows once in a while using torque wrench .

[@brucemadden1626]

Glad to see you using a dab of antiseize, a touch of silicone, and hand starting as well. On top of that, I always clean and blow out the spark plug well before removing the old plug. Always have the new plug ready BEFORE hand so the time for the exposed hole is minimal. Also, I use a thread ROLLER (TIME-SERT; 👍 this is NOT a thread chaser) and finally install the new plug

[@DanielDroegeShow]

Great video. I never use a socket to start the threads. It is too easy to crossthread them. I always use a small piece of rubber tubing on the porcelain end to feed it into the hole and now you will not have enough torque to damage the threads if it isn't perpendicular to the hole because it will spin around the end before getting stuck. I turn the plug left to loosen it until I feel/hear it drop and change direction because I know the threads are lined up. You can't feel that through a socket either. Many cars such as Mercedes and Infiniti require properly torqued plugs because they are indexed, meaning the spark has to be at the correct angle and direction to ensure proper combustion.

[@charlesmecum5009]

It's called reading your spark plugs to understand how ur engine is running, nice job Sherwood.

[@eric-tr7gf]

i gotta admit im surprised by this video from you guys. longtime subscriber to your channel and a ASE Master with L1, L3 and L4 here myself. 1st never use a gap gauge on most modern spark plugs. Feeler gauges or those set wire gauge. 2nd a big no no is to add anti seize to the threads. Most every spark plug manufacturer will tell you that. a neat trick to start the spark plus is to use a piece of rubber fuel line to start them. I have the plug starters made by a few people but also have rubber fuel line in different lengths 6in, 12in and 18in in my plug tool drawer

[@theroyaltyautoservice]

The rubber hose trick is a good one for sure! I'll do some research on the anti-seize. I know the use off aluminum anti-seize is a big no but I haven't seen anything on the copper. I'll definitely post an update.

[@marksd5650]

Great stuff gentlemen.

[@jameszeiger8533]

Great video. I believe the general guidance with regard to anti-seize that the torque needs to be reduced by 20% from the spec torque. The reason for this is your introducing a hydraulic compound on the threads and the plug shouldn’t be torque to full value because in fact with the compound you’d be overtorquing them as well. As well, there is some debate about reducing torque when using anti-seize, but the general consensus said it should be reduced. That said I appreciate your video and your expertise and how you do this.

@TStheDeplorable The opposite. Use aluminum antiseize for aluminum. I would not use copper antiseize with aluminum as I would think they are dissimilar and could react. Locktite makes a non-metallic antiseize paste that Bosch specifies to use on spark plugs used in industrial machine applications.
