2014 - 2020 Toyota highlander spark plugs replacement. Save money diy

[@majorcarlton137]

Clean the throttle body while u have it off. Don't forget to disconnect negative battery connection. Thanks for posting!

[@AJIMPORTS]

Thanks, good idea!

[@Row_Lift_Hike]

Very informative!! Made taking off the manifold look manageable in a home garage.

[@AJIMPORTS]

I did it in a drive way so you should be fine.

[@mattdoyle9914]

​@AJIMPORTS the Toyota dealership said I should replace the plenum and throttle gaskets. Do you do that?

[@georgebecht6357]

Thank you so much for posting the video, very helpful. It is KZbin's like you that add to the knowledge base that help others. Again Thank You.

[@mrme9517]

NICE BUT ANY TIME U HAVE TO PULL A INTAKE REPLACE THE COILS UNDER THERE LEAVE THE EASY 3 OR U WILL BE BACK SOONER THAN LATER

[@savedbygracesavedbygrace8308]

2024! Thank you for saving us lots of money!

[@hmongflyer]

Thank to this video! Help a lot. Been 5 year , I finally put some time to to replace all the spark plug on my 2016 highlander. Pretty easy, only hard parts is the 3 spark plug on the back because how tight it was behide there. I won't have to do this for another 5 year. Hhaha or I say 50k miles

[@AJIMPORTS]

Happy to hear the video was able to help you. 😀 beside spark plugs and transmission fluid/ fluid changes these cars are great.

[@breiss26]

Thanks for this! Just finished up the job in a few hours, very helpful!!!!

[@AJIMPORTS]

That's good news. Happy the video helped with your tune up

[@kuken1076]

I did my toyota highlander 2019 .it is take 4hours .thank you very much

[@realtalkrealreviews5061]

Great video. Sad thing they probably took it to mchanic and the mechanic didnt want to change the back spark plugs. I qm a firm believer in diy for the most part you will do a better job, not just to save money.

[@AJIMPORTS]

Very true and best part is once you learn. You are able to fix other ppls car and make a few bucks on the side.

[@JettaTDI2005]

Thank you so much. I am about to reach 95k on my 2016 Toyota Highlander

[@AJIMPORTS]

Make sure you get the gaskets for the intake manifold and throttle body.

[@Zeek800]

95k miles? That’s too long. Toyota recommends 60,000 miles but 55,000 to 65,000 works too. The Denso plugs are the proper Toyota Parts but when I search I get two Denso plugs for my 2017 Highlander ( different engine in 2017, still a 3.5 litre but some changes were made ). The first Denso plugs looked like the ones in this video but the second plugs had what looked like a “ triple tip “ over the electrodes. The other differences were the first ones are pregapped to I believe it’s around .40 and the second type of plugs is gapped at around .31. The 1st plugs are a bit cheaper than the 2nd type of plugs. DON’T adjust the gaps they come preset. If you remove the throttle body and its hoses you have better access to that 12mm bolt in the back of the intake behind the throttle body and can get the intake right out of the way. I would say to replace the intake gasket and the throttle body gasket and to get some CRC Throttle body cleaner ( don’t use carb cleanser or anything else ) and clean the throttle body ( Yountube it there’s a few things you need to know about what to do ) it wouldn’t hurt to get a can of MAF sensor cleaner and clean that too.

[@mattdoyle9914]

​@@Zeek800is it easier to remove the wiper blades and the shroud, instead of the throttle body? I saw one guy remove the shroud instead to get to the back plugs.

[@carlosdenully1080]

Hi how are you doing? I have a 2018 Toyota Highlander XLE right. Do I need to take my car to the Service Department at the Toyota Dealer so they can replace my spark plugs or can I buy it myself & do it myself? I ask because they are charging me over $700. Can you help please

[@videostellall]

Check/clean your throttle body usually fixes a hesitation on start. But yeah, those back plugs looked pretty bad

[@tommynanthavongsa415]

Thank you

[@matthewwangel]

This is only for the 2GR-FE. They switch to the 2GR-FKS in 2017. The procedure is different.

[@AJIMPORTS]

Thanks for the correct regarding engine model and year change.

[@ashishpatel1685]

You should never drop spark plug. When installing, always use a magnetic device or use a plastic pipe. You just literally dropped the spark plug in the borehole that will mess up the gap. kzbin.info/www/bejne/jHvCpJaImLCiZ68si=yLcJCHKZXMF14BlB use this instead

[@modakaification]

Wehere is cylinder 6 located? is it near the front of the engine on the far right side?

[@AJIMPORTS]

Front right cylinder.

[@dushaunhale266]

What about cylinder 1? Where is that located

[@saschagames123]

So cylinder 6 is actually one of the easy to reach ones?

[@mybrotherskeeper2428]

Think I’ll pass😂. I’ll give them my money on this one

[@AJIMPORTS]

Haha you might be right.

[@TreMoses]

Same...at least I'll sound like I know what im talkin about.

[@MrTurbo87lx]

No way im giving dealer 700 to replace plugs.

[@athymeforart6193]

was just quoted $1100 to change spark plugs cuz they have to drop manifold to get to plugs. 2014 highlander xle

[@AJIMPORTS]

Wow even replacing all the gaskets it's no more than 200 in parts and maybe 1.5 hours shop labor. A 400 job at most.

[@athymeforart6193]

@@AJIMPORTS thought that was ridiculous. Thx for the input

[@tommynanthavongsa415]

excuse me sir can you tell me code P0302 state that Cylinder 2 misfire Detected.is that the same thing as spark plug? please let me know as soon as possible thanks

[@AJIMPORTS]

Since it's the front left I would just change the spark plug since they cheap. Also put in a Injector Cleaner in the gas tank and fill up with 93. But that code could be spark plug, coil pack or fuel Injector. But start with the spark plugs first

[@brianobegi4882]

Did you change the gasket for the intake manifold?

[@AJIMPORTS]

No I did not. The one on the car was fine. But I would recommend it if the car near 100k miles

[@jakedior9419]

Low mileage on car buy plugs are in such a bad shape?

[@AJIMPORTS]

Once over 50k I feel plugs should be changed. Don't know why the plugs were like this.

[@michael91101]

What size Allen key bolts hold the intake on? I only saw the 12MM bolts.

[@AJIMPORTS]

Not sure.

[@ternuc]

5mm

[@noka55]

Which one is cyl 1

[@AJIMPORTS]

Back left cylinder. Near passenger side

[@richarddaway3818]

Not bad boss. V6 toyotas have the worse set up for.spark plug locations.3 in the from and 3 in the back.worse one i had done was an 04 camry v6. Let me just add to double check that gap of your new spark plugs as some of it are off the recommended gapping out of the box.But otherwise awesome video!

[@AJIMPORTS]

It a pain to do but it's still cheaper than paying someone to do it.

[@jonathandavis132]

That’s v6 transverse engines in general

[@mikemauldin1]

Can anyone help me out? I have 62,000 on the 2017. My car is running fine. Was wondering if I need to put plugs in

[@AJIMPORTS]

If you can do the work your self then do it. Normally recommend for 80 to 100k range. I do mines every 3 to 4 years

[@markg999]

I think they are due at 10 years or 110k miles, you are fine for awhile. Atleast was for my 13 Lexus ES350....did mine this year took a few hours and didnt have to remove the intake just the cowl.

[@roberthelgeson1294]

How long does it take in total would you say??

[@AJIMPORTS]

Give your self 3 hours. You can be done in 1 but we all know stuff happens when you rush.

[@jimregan2769]

What is the recommended interval for spark plug replacement on 2016 Highlander? I've seen a wide range of answers online.

[@AJIMPORTS]

Toyota recommend 100k. Personally I would do them 50k or 4 to 5 years for any car. It's cheap insurance once you know how to do the job your self.

[@TheBagarali]

Original spark plugs on this engine are Denso iridium plugs and Toyota recommends 144 monts or 120k miles. Changing them at 50k is basicaly stupidity. I have currently 126k on them and will thinking about replacing around 135-140k as the car has mainly highway miles.

[@mybrotherskeeper2428]

The article I read from Toyota recommended doing at 60k

[@AJIMPORTS]

@@mybrotherskeeper2428 with normal driving thats around 4 to 6 years. Thats not a bad time frame.

[@SirRommy]

@@mybrotherskeeper2428 My 2015 Highlander service book also says 120K. I have the 2GR-FE engine.

[@Bluecollarguy87]

How many miles were on it?

[@AJIMPORTS]

Around 50k on the Car

[@larrykudrna2953]

Which Denso did you get from Rockauto ? As the two Denso Platinum they show fit have two different gaps. One is .032 and the other is .040.

[@AJIMPORTS]

i went with the .040.

[@richarddaway3818]

Read the recommended gapping in your manual and get a spark plug gapping tool.costs about a dollar as some of the plugs are off the gap coming from box.

[@islandboy3189]

I'm at the dealership right now and they want 975.00 dollars to change the spark plugs I can do this my self lol.

[@AJIMPORTS]

Yep just make sure to buy the gasket for the intake manifold. Don't want more problems when trying to save money.

[@yeulakho6574]

ugggh.. the transverse mount engine, a pain to change spark plugs.

[@Stantheman0627]

Those back plugs are a pain in the.........

[@AJIMPORTS]

Yes they are. But this is the best way I found to do it.

[@iishyxvietxboyii1]

V6 man.

[@chikilin1773]

Im just going to trade my highlander with a different vehicle thats more easy to work on.

[@AJIMPORTS]

its a pain but over all its a good suv with not many issues.

[@J.W.W.]

Yeah, good luck with that
