How to Change Spark Plugs in a 2019 Toyota Highlander - D4S V-6 Engine

[@thomasroberts8024]

Lexus dealer Service Advisor gave me a quote of $1110 for a 60k service the day we bought our L/Certified RX350 back in 2020. I've thought long and hard about that figure but was put off by the fear of that job you did 2 months ago. After all, I'll be 79 in 12 days! But, last Saturday I changed the coolant and, armed with videos from The Car Care Nut and Victor G Automotive I was slowly working up my courage. Now, seeing you tackle this toughie and come out for the price of plugs and gaskets, I've made up my mind! Thanks for your example!

[@seanoneil277]

Thank you for this, Mr GB. I have a '98 Tacoma that I once went to change the plugs on, only to find that of the 4 plugs one was beneath the intake manifold just as is the case with the V6 engine here. When I was in my 20s I did such work routinely, but these days I'm lazy. I paid a garage to do the tuneup at 75k for this reason. I've said it before, but you're one of the most mechanically handy people I've ever watched. I can imagine you taking apart a clock when you were a kid. God bless you & your family, and give Benny a scratch behind the ears for me.

I grew up in a farm/transport/combine/shelling family company.... To say we had tools, is an understatement.... I went to replace the worn serpentine belt on my 93 Chevy cavalier.... All I needed was a long handled box-end wrench to pull the spring-loaded pulley tensioner... I must have spent 3hrs looking for the tool or combination of tools to do the job.... I finally gave up, drove to Sears, bought the wrench. When I got home it took like 2 min. Damn, what a fiasco... Sometimes it's all about having the correct tools....

[@G1951-w1y]

I just did my 2017 Tacoma V6. 1st time, took it slow, took photos, about 4 hours. Not too bad for a 72 year old retiree.

[@kuken1076]

I did my toyota highlander 2019 .it take me 4:30 hours do the job.thank you very much sir

[@correr96]

Thanks for the video. My dealer wanted $800 to change the plugs in my 2019 Highlander. I have fairly decent mechanical skills, and with some patience, i think that i can do this.

[@tgriebe]

That's only $800 an hour for labor.

[@k_kelsey]

We have a ‘19 highlander. Such a great vehicle. Roomy, smooth on the Highway, and capable on the off-roads. Pretty Decent gas mileage.

[@GunBlue490]

It's the best vehicle we've ever owned, hands down.

[@shadythereok]

We have a 07' Kia Sorento, the last 3.8L. Having to remove the intake really makes a tune-up expensive

[@henrybobswillikers]

Hi GunBlue,Great to see you !

[@Rheasound]

excellent tutorial! I think is a good opportunity to clean the body throttle too. Thanks for sharing. Cheers from Fla.

[@krazyrican2009]

I too own a 2019 Highlander. Thanks for the video!!

[@justinturdeau2383]

Gunblue, any chance you’re going to do a series on fine-tuning your already accurate loads out of your 270? Can you take it one step further now to really dial it in? Thanks.

[@michaelpoulin3445]

I was curious if you have ever seen a Ruger model 77, blued, that came in a Zytel/paddle stock from the factory? Or has that rifle been restocked at some point? I would appreciate the input.

[@gwcracker]

Is there a reason for the early plug change? Should be good for 120,000 miles or more according to my research.

[@GunBlue490]

120,00 miles has never been given for factory original equipment platinum plugs. They are stated to last for 60,000 miles, which was exactly when this car began to demonstrate a loss of acceleration and mileage. No, it was certainly not an early plug change; it was perfectly in time with the afore stated life. I replaced the platinum with iridium plugs, from which I do expect considerably greater mileage.

[@ashishpatel1685]

What brand of Torque wrench you use ? the click is very audible ?

[@HypocriticYT]

My vehicles have spark plug intervals of 90,000 miles 😊but changing them earlier when you see any black soot in the tailpipe is a good idea 👍

[@ross1342]

Great video just one thing I didn't see you tighten throttle body hose clamp , always enjoy your videos . cheers

[@GunBlue490]

My primary objective was to illustrate the essential process, not to grind through the basic and mundane details.

[@tman900]

Great video, can you do more Highlander maintenance videos please.

[@HypocriticYT]

Let’s hope that the plugs solved the hesitation. I find once an engine is hot the modern gas can vaporize in the line and create similar conditions. Also the beginning of a failing fuel pump or dirty throttle body

[@GunBlue490]

It's running great. Thank you.

[@HypocriticYT]

@@GunBlue490 that’s great because no one likes the parts cannon

[@BMBangladesh]

Awesome ! Thank you for giving us hope and courage.

[@davidwitkowicz5024]

I noticed that you live here in New England and wondered if you could help me with a gunsmith in my area that does trigger work in the South Coast area it’s for my S&W model 66-8

[@ashishpatel1685]

I can't wait to replace plugs in my highlander currently i am at 108k factory plugs.

[@mikem-wk7lu]

Oh man i wanted to hear it run. Enjoyed the video though.

[@disturbedmaynard3873]

I sure miss the days when you could open the hood and change the plugs on a V8 in just a few minutes. I have a Honda Ridgeline that I had to change plugs on recently and those back 3 plugs requires you to be a magician to get them out and back in properly. I won't talk about the valve cover gasket replacement on it. Give me a late 60's early 70's engine to work on any day.

[@GunBlue490]

I remember those days, too. You have a very selective memory! Being under the hood was a constant routine. Frequent plug, point, distributor cap changes, timing wandered, tires with no life, rusted, perforated bodies in two years, cars were celebrated if they went "around the world", bad chokes, cars wouldn't start on cold days without half a can of ether, batteries that constantly required refills, no A/C, electrical systems that didn't work. Getting to work late because a car refused to start. The industry produced junk and expected folks back for a new one every two years. Those were the days, for sure.

[@HypocriticYT]

Putting it back together without having parts left over 😊

[@Bill-jv5eg]

Nice job,,,,,I’ll bring my car up next😄😄😄😄

[@mikemyers8538]

Not so bad a job in comparison to changing out the starter motor on something like a 2014 Mercedes Benz ML 450 where it's required to remove the engine, transmission and front suspension subframe only to gain access to the starter. 10 hour job under warranty. You need a hoist and a table to perform the repair.

[@GunBlue490]

Horrendous service costs are quite typical of German cars, even with VWs. The person who owns one either regrets such costs, or doesn't need to consider them.

[@chrischiampo7647]

Next Video Timing Belt and Water Pump Replacement 😊😎 Mr Gunblue

[@GunBlue490]

I hopefully won't require that.

[@lucaszibell1562]

There is no timing belt on this vehicle. Toyota started using chains in all their motors a long time ago. As for the water pump, its 5 hours of labor at my dealership and have seen other shops quote even higher.

[@johnkale6302]

You are awesome.

I dread when my Dodge hemi truck needs 16 spark plugs 😮and they are all iridium 😢

[@frankwong294]

Just finished the job last night on my 2011 Hemi with 100,000 miles. Day 1 - did 10 plugs ~1.25 hrs, Day 2 did the last 6 (back two and the one under the master cylinder) 2 hours. To get to the back 2 cylinders I had to lay a 2x8 across the engine compartment to lay on so I could reach. It wasn't too hard to do but it was a tight space that created the challenges. 6" long 5/8" magnetic plug socket with flex head was the ticket. You won't be able to do the job without it.

[@mark-wn5ek]

My 2019 Tundra will get fresh iridium’s at around 100,000 miles. Changing iridium spark plugs at 50,000 is like changing synthetic oil at 6,000….total waste. I’m a bit younger than you but not a lot and having been driving over 50 years, I’ve paid my money and bought my experience. Never ever experienced an engine failure from any make of automobile. My 53 Chevrolet did develop a rod knock but never let go. The last three new automobiles have gotten synthetic oil changes at 15,000 miles and none have used oil! 2012 KIA Sorento currently has 245,000 showing. Good engineering and quality fluids and parts give excellent service compared to 1970!

[@sjc3081]

15,000 mile changes on three separate cars with no issues. I call 100% bull crap.

[@mrsmith8436]

@@sjc3081 Yep - Just ask care care nut guy. ASE Certified Toyota Master Mechanic for over 20 years and he has a dedicated video BEGGING people to change their oil 5-7k miles if they want to not have oil burning issue despite what the dealers tell you and the manual says. In fact if you actually read the manual almost nobody meets the driving standard for 10k mile oil changes.

[@HypocriticYT]

Extended oil changes can effect the oil control rings on the pistons, gum them up and then oil bypasses into the combustion chamber 😮

[@WookieLove1]

God Bless Mr High mileage oil change. Thank you for enlightening us all.

[@roshanweerasinghable]

NEED SOME LIGHT ON THE VIDEO. MOSTLY SHOWING THE MECHANICS ARM.GOOD CONTENT.

[@GunBlue490]

I had two strong video lights on the subject. The engine compartment is black, which absorbs light, beyond my control. Though I am sure that you did not intend to yell, please refrain from the use of all capital letters, which is considered angry "yelling".

[@davidgoldberg]

Boss, you're good but I've heard that those Toyota spark plugs are good for 100,000 miles.

[@GunBlue490]

The original platinum plugs began to cause hesitation at 60,000. Iridium plugs that I installed do last upwards of 130K.

[@gwcracker]

@@GunBlue490 The plugs you replaced were good for 12 years or 120,000 miles. You are living in the past when cars had to be maintained every couple thousand miles. I was there too and I'm damned glad it's not that way now. Remember when you could change 8 plugs in half an hour? It was because you had to do it...not doing it just to make a video.

[@majorpayne5289]

👍Thx GB

[@aaronwilcox6417]

That looks like a pain. I'd rather be shooting a 22-250 out in central Idaho. To bad don't have one, so I'll suffer a 243win.

[@k-9thecat765]

Yip,...they make it so hard to DIY... At least you don't have to remove the hood and lift the engine out...

[@GunBlue490]

You either aren't old enough to know about the "good ol" DIY days, or you forgot them! Let me take you back to those halcyon days! Cars were easy to work on because they just had an engine that got 8 MPG connected to a drive train with 3 speeds. Engine compartments were big enough for half a sheet of plywood to fit comfortably under the hood. There was no A/C. We paid extra for a radio and heater, and that was AM, not FM. We changed oil every 2,000 miles. We got 5,000 to miles from plugs if we were fortunate, replaced plug wires every other plug change, and we were constantly adjusting and replacing burned out points. Rotors burned out and distributor caps cracked before they burned out. You had to understand how to set the point gap, which constantly changed as the points burned smaller. DIY meant owning a timing light and knowing what dwell worked to keep your engine running. It took two people to time an engine; your wife to hold the timing light and you to turn the distributor until she hollered "That's it!". "Nope, it moved!" "Go back!" "Too much, the other way!" "I'm going in to make supper, call Jack". Car problems caused divorces, and the wife got the car. People didn't own two cars. One was frustrating and costly enough. Vehicles needed a complete grease job with countless Zerk fittings on a lift with every oil change. Carter chokes stuck and engine timing wandered. Carburetors were always getting out of adjustment. Engines, constantly out of tune backfired, hesitated, got poor(er) mileage. On a cold frosty morning, every hood on the block was up, with guys in their best work suits cussing and spraying ether into their carbs, with a dirty air filter can on the snowy sidewalk. Oh, the sound of ruruhruh ruruhruh filling the air! The sound quickly diminished as the batteries died, and were replaced by clicking ignitions and hoods slamming just before taxi cars arrived. Parts we expect to get 60,000 miles from lasted a few months, maybe, if you didn't drive more than 10,000 miles a year. Flat tires were an expected part of a summer 300 mile road trip on a hot road, and everyone became expert at getting from the left lane to the break-down lane. You considered yourself very lucky to get a season from a set of tires before having a flat repaired. A season meant two per year; summer and winter, not a year. We got a year from our unsealed batteries that needed constant refilling and checking! Front end misalignment was par for the course and kept countless shops busy. Mufflers? We replaced rusted out mufflers as often as our Gillette blue blades. New vehicles came out of the factory with more defects than a new owner could keep track of on a steno pad before the first service call. Squeaks, rattles, missing bolts, stuck window cranks, and leaking engines. A car or truck that managed to "go around the world" (that was the saying) with 99,999 miles was written up in the local paper before it went to the junk yard. Odometers didn't have six places because manufacturers didn't expect more from their junk. People bought a new car every two years because their old one was shot, not because they were rich. Oh, the good old days! Funny how romance has blurred some people's memories. I'll never forget. We want a monster 280 HP engine, A/C, power steering, power brakes, overhead cam, front wheel drive, fuel injection, electronic ignition, computerized everything, quiet acceleration, miles of wire for the the 13-speaker sound system and Blue Tooth, all stuffed under a high mileage compact hood, seating for 6, and a car that obediently responds whenever the keyless ignition button is pushed, and all that to last an expected 300,000 miles with tire and plug changes every 60,000. It's the over stuffed stuffed toy box that everyone wants. It's not intentional. I'll take the difficult to DIY cars.

​@@GunBlue490 Weren't they great old days. Up hill both ways to school walking in 3' of snow!

[@jayjason423]

GDI engines require shorter plug intervals than the older NA engines. It was nothing fancy, but my 1998 olds cutlass, while it leaked oil and had other accessories changed, went 400K miles with only 2 plug changes and had original ignition modules and wires. The original trans failing is what finally did her in. Car never left me stranded. But hey, the inconvenience of shorter maintenance intervals is for the environment. While we do that the rest of the planet did not get the message. Other “groups” are encouraged to breed, go west, and then breed some more with generous reproductive subsidies for a net increase in CO2. It is all a chimera to make things more expensive for the fair hued. Best stop trying to interpret the bible by guesswork, and instead pay attention to the genocide to which your own kind is being subjected. No interpretation of the bible is valid which would result in fair hued genocide. If folks don't have the will, the juice, or the balls to stop it, at least stop arguing for it. God Bless.

[@GunBlue490]

You are a fabricator of tall tales. I'll be plain, because I was there in those days. You NEVER, EVER got 400,000 miles on three sets of plugs in any Olds Cutlass, or in any car, and I'd like to see documents about your miraculous 400K GM car.

[@jayjason423]

@@GunBlue490 The car was born around 1998, whereupon it was driven by my parents for a few years and had its lower intake gasket replaced, which they are notorious for. I then proceeded to gently drive 120 miles a day -90% highway- for around 10 years to and fro work as an Actuary, until my newer model Chevy Malibu. I have a coworker who will vouch for the longevity and mileage of the vehicle, and my frugal nature, which is all the proof I have. I did all oil changes myself, and since the rear plugs were a PITA to change I only did it twice. I have nothing to prove to anyone. A fat wallet is all the satisfaction I need, and If folks think GM is junk, that just keeps their cars cheaper for me. If I start talking about that fat wallet that will be decried as more tales so why bother. As for the “other tales”, one would have to be math challenged not to see it. Of course one cannot use “hue” or even proxies of hue in determining insurance rates (the powers that be say that is “unfair”), so expect to pay higher rates to supplement other irresponsible “groups”. After all, that's only fair right? Give them our territory, jobs, commit to “mixing”, cultural debasement, and reward overpopulation all while pastors say it is “moral”. Talk about a big lie. Homo sapiens, meet homo idioticus! But what else should I expect out of someone who protects political animals from their just desserts by working with the FBI. I see right through the Mr. Rogers act. Somehow I don't see God blessing this.

How to change the plugs? Sell it to me cheap and I’ll take care of it 😊
