Thank you for this video. It was going to cost me $600 to get my plugs and one coil replaced. After finally getting to the rear plugs I went ahead and changed all three rear coils just so I don’t have to do this again anytime soon. Couldn’t have done it without your video. I also now understand why the cost was so high. Very labor intensive.
Very good video, u must have long and small arms. I had to change # 5 plug was bad replace it and coil. It went back together faster then it took to it apart. I tryed to get in the way u said weir no avail. If Toyota had moved the engine 3 or 4” to the front a person could do it very fast, too. Thanks
This video is very good for changing rear spark plugs and chance to clean the manifold at the same time. However, if you have small hands and arms and don't want to spend a lot of time to remove the manifold, throttle body housing, and its extension then you can try change the rear spark plugs using your right arm. Use your right hand, from the right side of the manifold (below throttle body housing) going left just below the manifold. Before removing the rear spark plugs you need to remove a few things around that area like cruise control cable and its bracket which is in front the manifold and throttle body housing. This step helps create more room for your small right arm. The hardest part to remove is the middle rear spark plug electrical connector. Once you remove it then it is not too hard to remove that middle rear spark plug. I was able to change my 2002 highland this way because my hands and arms are small. I suggest that anyone having small hands and want to change the rear spark plugs then first try to see if you right hand is small enough so that you can feel there is some room for you to remove the top screw of the middle rear spark plug and if so then you can proceed. As for the left rear spark plug I removed a few things to the left of it to create room before removing it.
Hi Ryan, I just used your video to change the spark plugs on my 2006 V6 Highlander. This was a great video, although there were some differences with the vehicle in your video, I would not have been able to do this without your video because of the great level of detail and step by step descriptions. So you can get an idea of my level of experience, the extent of my experience was changing the brakes on my Highlander. I will say that I tried tried cleaning the throttle body based on your secondary video but wasn't able to get the throttle body off of of the intake manifold. All in all, the project was a success...thanks for the video!
Thanks for taking the time and effort to make this educational video! Im not a mechanic but your video gives me the confidence to get it done. Keep it up and AWESOME JOB!
Man I am not excited to jump into doing this tomorrow. Gonna be a all Saturday project it looks like ,2 days if I lose my patience. Thank you for the detailed video and listing all the sizes needed before tackling this ,extremely helpful. All though I’m teetering on paying someone else to this for me for the first time in my life. Getting too old for this.
I just took a part in 04 that had all six of the original plugs at 270,000 miles iridium plugs were probably in the worst condition I've ever seen sparkly but they were still working pretty good actually
I just recently work on one replacing the knock sensors and that 14mm bolt in the back gave me such a headache. I found it so much easier to go under the vehicle and get the volt from the bottom. Took me like a minute to take off once I got it from down there. Just FYI for next time or for someone in the future!
Such an underrated video. I'm super impressed and grateful for you uploading this. This makes my car buying experience much more informative when looking at the maintence I'll have to do. 👌🏼
This looks like too much work, lol. I may just pay someone to do it. But thanks for showing me how much of a pain it is. That bold in the very back that you couldn't get a wrench to, I think that was the deal-breaker for me.
Thank you so much for making this video. I picked up an 08 hybrid Highlander and aside from having 2 of those hidden manifold screws, it was spot on. You are a lifesaver.
Thank you! Very easy to follow (I was lucky, I only need to change the #4 coil/plug). Saved me a bunch of money. Your explanation was clear and concise - well done!
Thanks for your effort of a good video. And an opinion on the Antiseize debate...None of the plug manufacturers recommend antiseize on plug threads. Modern plugs have a coating to ease removal. Also, lubricants affect torque values. And...lubricants are detrimental to heat dissipation. See NGK, Bosch and Denso.
I did this yesterday and learned some things. If you don't have a plug you can use a tire valve cap. For removing the bottom bolt connecting the throttlebody from the intake manifold you can use a long extension instead of a ratcheting wrench to not risk rounding out the bolts.
Thank you for saving me tons of money! I desperately needed this done and I’d rather do it myself since I have the time but now the money 😅 🙏🏼 thank you!
The best video about hillander and sienna to reach rear coil i thought i was gonna telm my friend to take it some where if anything happen but after this video i can do it easy you make it look so simple thank you so much

Changed the back 3 plugs and coils. A little tight I have biggish hands. Used a flexible extender for plug removal. Just need a lot of patience. This thing was made in japan. Great vehicle for being over 20.
The step-by-step tutorial will help me replace the spark plugs where the intake manifold is. I suggest that since 1, 3, and 5 positions are complicated to work on, I will also install new ignition coils, so I don't have to worry about them in future. Just a thought. I really appreciate the video. Thank you.
Great video!! Thank you for sharing the goods with us. I just bought a 2002 Toyota Kruger(Highlander) v6 3L imported from Japan. I love it! It only has about 76,500 kms on it, and is in excellent condition, so I feel really really fortunate to have found her. Watching everything I can about this vehicle. How many "shop hours" should I expect a non-toyota shop to charge for the labour on the sparkplugs replacement? Thanks alot!!
Thanks for the tutorial. This part actually doesn't look very bad. The throttle assy with it's vac lines, coolant lines, linkages, and electrical connections seem like more of a headache
Well you don't put dielectric grease on the threads. I put anti seize. I disagree with Toyota and I'm not trying to sell you a new Highlander if a plug locks up in the head. Thanks for watching!
Just changed the plugs on my daughters 2002 Highlander.,220,000 miles and the plugs came out with no problem. There must be a reason the manuf. and other experts say not to put anti siege on the threads. Possibly debri entering the engine. Instead of giving a sarcastic reply maybe you might want to look into it. Oh, only had to remove half of what you did.
Thanks for this, I have been dreading to do this dor a while now. I was able to take out the far right one without removing it but the other 2 are still there.
On my 07 3.3L, there is another mounting bracket that holds the intake manifold on the right side and sits at a 5 or 10 degree angle downwards, just to the left of the throttle body. It is in a tighter and worse position than the left mounting bolts that was shown in this vehicle, which I was able to get with a 14 ratchet wrench. It is also worse than the throttle body mounting bracket bolt. Unfortunately, the other bolt seemed to be stripped prior to trying to get it off, hopefully the shop can cut it with a torch. Literally one of the most grueling ordeal Ive dealt with haha. What an awful design just to change spark plugs. All because of a bolt you cant see, who hires these idiots? Thank you for the video, it is well done.
You can do this without taking anything of besides the coils,but it will take you just as long and be just a frustrating,it’s just a different flavor of a annoying.I have done it both ways
Just did my knock sensors…. Now when I start it, it dies, or rough idles, until it settles out. If revved up it bogs until it overcomes enough to raise rpm’s. Any ideas what it could be?
GREAT VIDEO !!! I have to say, I am unsure of your accent, but your voice is extremely similar to Max Headroom (that is meant as a compliment!)… probably not the first person to point that out I’m sure… Anyway, really really awesome job on the video!
Wow, thanks! I guess just generic southern California is my accent. Never head it before but I looked it up and I hear what you are saying. Thanks for watching!
Hey Ryan, great video! The bracket that the F.U. bolt went through was probably used at the factory to support the engine when it was lowered in from overhead during installation. If I were going to leave it on and reattach the bolt, I would take my grinder and cut off that pesky curved part that is in the way. Me, I wouldn't bother with reattaching it thus making the job a little easier next time. Keep up the good work.
Unbolt the 2 support brackets underneath instead of fighting the bolt from the top just make sure you unbolt the P/S hose brackets and take manifold out with support brackets ezy peezy.
Thanks for your help! I just changed my 2007 Highlander's spark plugs. My intake manifold is plastic and I couldn't get the rear bolt back in. I hope it's fine!
I would recommend buying a magnetic spark plug socket. It ensures that you don't loose your spark plug and have to retrieve it. It's cheap insurance and makes the job so much easier.
How bad is it really to get that one supporting nut off the back? I did valve cover gaskets + Spark plugs on a Mazda 6 (v6) and this looks easy compared to it. I need to do my Highlander and this gives me anxiety because you’re making it seem hard, but it doesn’t look hard at all.
I kid you not all but 1 bolt came out . The left intake hex bolt was not having it watsoever... I literally could not get it to budge sprayed some penetrating Oil and used a Allen socket tried all methods nope didn't come out lol. It's really in there. I had to put everything back together going to try it a another day. Back to the drawing board I guess. Toyota may have won round 1 but ill win round 2. Any advice?
@@2carpros I would consult the manufacturer on this...NGK recommends installing their spark plugs without lubrication or anti-seize. Anti-seize can be harmful to NGK spark plugs and may cause engine damage. NGK spark plugs have a trivalent plating on the threads that acts as a release agent when removing the spark plug and provides corrosion resistance.
@10:28 you didn't show us how to take the intake off.. video was great but missing that part for me since I need to change a coil that's misfiring from the 5th coil.. thanks..
I really liked your video. Apparently, some people had some luck going after that back manifold bolt from under the vehicle. Also, isn't it a general principle to tighten inside and work your way out? IOW, when securing the manifold, wouldn't it be better to lightly tighten the two inner Allen bolts, lightly tighten the outer bolts, tighten up the Allen bolts and then the outer bolts, and then then torque the Allen bolts and outer bolts (for those doing this manually like myself)? Again, thanks for the methodical and clear video -- my notes from this video will follow me out as I do this job myself! :-)
@@2carpros I did this job two days ago on the 3.3 engine in a 2004 Highlander. It has two of those back bolts. The one closer to the center of the engine bay was very difficult. Manifold protrusions prevented the wrench from sitting correctly, and the difficult bolt was in waaaaày too tight. The open side of a 14mm wrench can do both, but if they are very tight it can be very hard. On the 3.3's bolt near the center of the engine bay, the wrench has to come off at an angle due to two manifold protrusions. You only have about 30-40 degrees to move the wrench, and this must all be done by feel. I ran a 2x4 from the strut mount across the body to a structurally sound part of the body and then a second 2x4 across the first one resting on the top of the front quarter panel so I could get on my knees on top of the engine to do the work. Cover the body contact areas if you want to protect the paint. It takes time -- so buckle up and be patient. And don't strip it. Mine was damaged already, but still useable. If yours is damaged, it is best to replace it before reinstalling it. When putting those two bolts on, installed them first after you seat the manifold, otherwise, you may not be able to seat them in their home to secure them. Also, don't over tighten them. On the 3.3, it is not necessary to remove the coolant hoses. You can "roll" the throttle body off to the right. There is a video related to the 3.3 Highlander engine break down to remove the valve cover gasket. Many of the steps are the same, and if you do all these steps, it makes sense to replace the valve cover gaskets, too.
Awesome job! Haven't worked on that motor yet. Lots of work to change plugs. I understand the oil filter on this car is a hassle also. Not what I expect from a Toyota. What plugs do you recommend?
Could you just take out the intake bolts and grounds and move the entire assembly back a little without taking off the throttle body to get to the rear spark plugs?
Not really. You would be bending the mount strap and it might break a piece of the intake plenum. I would just do it the hard way and not worry about it. Thanks for watching!
Thanks for making the video. Had to replace cop on #3. It would have been a bear without this video. Now I need to replace front head gasket. Did you make any videos on that. Doesn't look to complicated but any help would be good.

NGK spark plugs have a trivalent plating on the threads that acts as a release agent when removing the spark plug and provides corrosion resistance.
😆 yeah. Automotive engineers of this car answer to Darth Vader.
- Thank you.
Great video. Great work.
How did you get the stubborn nut out?
True.
A lot of effort. Rocking the engine forward a quarter of an inch helped. But it was very challenging. Thanks for watching!
Doing this currently I hate that rear manifold bolt
@10:28 you didn't show us how to take the intake off.. video was great but missing that part for me since I need to change a coil that's misfiring from the 5th coil.. thanks..
Maybe check this video out if you are confused. th-cam.com/video/bXyF3aP4GyY/w-d-xo.html Thanks for watching!
I really liked your video. Apparently, some people had some luck going after that back manifold bolt from under the vehicle.
Also, isn't it a general principle to tighten inside and work your way out? IOW, when securing the manifold, wouldn't it be better to lightly tighten the two inner Allen bolts, lightly tighten the outer bolts, tighten up the Allen bolts and then the outer bolts, and then then torque the Allen bolts and outer bolts (for those doing this manually like myself)?
Again, thanks for the methodical and clear video -- my notes from this video will follow me out as I do this job myself! :-)
Thanks for watching! I tried going under the car but my darn hands wouldn't fit. Yes that is a good way to go about it. Thanks for watching!
@@2carpros I did this job two days ago on the 3.3 engine in a 2004 Highlander. It has two of those back bolts. The one closer to the center of the engine bay was very difficult. Manifold protrusions prevented the wrench from sitting correctly, and the difficult bolt was in waaaaày too tight. The open side of a 14mm wrench can do both, but if they are very tight it can be very hard. On the 3.3's bolt near the center of the engine bay, the wrench has to come off at an angle due to two manifold protrusions. You only have about 30-40 degrees to move the wrench, and this must all be done by feel. I ran a 2x4 from the strut mount across the body to a structurally sound part of the body and then a second 2x4 across the first one resting on the top of the front quarter panel so I could get on my knees on top of the engine to do the work. Cover the body contact areas if you want to protect the paint. It takes time -- so buckle up and be patient. And don't strip it. Mine was damaged already, but still useable. If yours is damaged, it is best to replace it before reinstalling it.
When putting those two bolts on, installed them first after you seat the manifold, otherwise, you may not be able to seat them in their home to secure them. Also, don't over tighten them.
On the 3.3, it is not necessary to remove the coolant hoses. You can "roll" the throttle body off to the right.
There is a video related to the 3.3 Highlander engine break down to remove the valve cover gasket. Many of the steps are the same, and if you do all these steps, it makes sense to replace the valve cover gaskets, too.
I used a 1/2 inch socket 14mm and socket wrench it fit but the 14 mm bolt from hell was still a job.
Thank you for the amazing guidance. I will subscribe
Awesome, thank you!
Awesome job! Haven't worked on that motor yet. Lots of work to change plugs. I understand the oil filter on this car is a hassle also. Not what I expect from a Toyota.
What plugs do you recommend?
Thanks for watching! Those NGK plugs I used in the video are the ones I would recommend. Thanks for watching!
Oil filter is right under exaust manifold. Super easy to reach it from the top.
Hello where can I find the tool to open behind 14 mm bolt and what that call please let us know I appreciate
Good job, thanks for sharing.
That bolt is there for (as far as I know) all 2008 and older Toyota v6’s
That's an annoying one for sure! Thanks for watching Jacob!
Could you just take out the intake bolts and grounds and move the entire assembly back a little without taking off the throttle body to get to the rear spark plugs?
Not really. You would be bending the mount strap and it might break a piece of the intake plenum. I would just do it the hard way and not worry about it. Thanks for watching!
Can the intake be taken off without removing the entire throttle body?
Yeah probably. Thanks for watching!
What is the product you applied to the plug at 7:07?
That's anti seize and the link is in the description. Thanks for watching!
Thanks for making the video. Had to replace cop on #3. It would have been a bear without this video. Now I need to replace front head gasket. Did you make any videos on that. Doesn't look to complicated but any help would be good.
Thanks for watching! I don't have have a video on that at this time.
Have you don this on a 2000 Lexus RX 300?
