Spark Plug Replacement Toyota and Lexus V6 

Now that is how you do a DIY video. No endless jabbering on about useless info. No skipping over vital details. Showing each step, but fast forwarding or skipping to next step to keep things short. This is real quality professional stuff. Excellent work!

This is the best 3mz-fz 3.3 liter engine spark plugs replacement video on RU-vid.

Best mechanic's video I have seen yet. He didn't stick his face in the video like some wannabe Hollywood actor, he didn't skip any steps (well he didn't show blowing out the front plug hole but he did say to do it earlier), he spoke clearly, he called out the wrench sizes, he anticipated what to expect next, etc. I can only fault him for not putting in the 18 ft/lb torque to the plugs and the torque on the intake plenum bolts and cautioning to go easy on the coil pack bolts. The torques could go into his video information as one other guy did. Otherwise he did it right. I'll subscribe and hope he makes some money and a lot more videos. Why would anyone downvote this video? 32 idiots.

You're a legend now. This Toyota 3MZ-FE owner thanks you for the insanely great efforts to help us all.

Had a guy do this job last year he didnt Tighten the bolts on the intake.Now I can Finally stop the rattling that's coming from my car thanks to this Video!!

The best DIY video I’ve ever watched, some people make a lot of cuts in which you get EASILY confused but this video is really good! Now let’s change some spark plugs! 👍🏽

Thanks, I'm glad I can help! It took about 5 hours, including breaks, taking photos and shooting the video. I could do it again in 1-1.5 hours. Its not hard, I encourage you to try it.

That fishing line tho tied to the bolt, very smart. Ive spent countless hours trying to find bolts when you drop it

Gentle voice, clear video, shows brackets and placement of bolts, step by step break down and rebuild. I would watch an add for few. Or send you beer money. Thank you for the quality videos.

I finished the job today and couldn't/wouldn't have done it without this video! I watched the video 3-4x before starting, set up the laptop next to the car, and followed it step-by-step. It took a little over 4 hours, but i was proceeding carefully and doing some clean-up along the way. No problems. The only thing I'll add is that, when dealing with those pesky bolts in the back, make sure to jiggle the plenum as needed to avoid binding - it took forever to get the 14mm bolt out since the weight of the plenum was forcing the bolt against side of the hole. Also, a 1/4" drive rachet is small enough to use on the outer 12mm bolt. Thanks again for a great DIY video!

Came back to this video 5 years later to replace spark plugs and other maintenance... I can't get over how much of a MAJOR PITA those 3 bolts are behind the plenum... WOW, it took me almost an hour. They are in such a horrible position... :-( Awesome video again!

Thanks for the instructions. It took me about 4 hours to replace the valve cover gaskets and spark plugs. Couldn't have done it without this video!

You sir are a officer and a gentleman. Great presentation. Showed the brackets to give us a better visual of where they are, size of the bolts, etc. Perfect mechanic video. Step by step. Clear. Concise. Way better than the other plug vids I saw. My 2002 es300 just hit 240,000 miles.

Great tips on tapping the intakes to avoid falling debris and tying the fishing line to the rear bolts is simply inspired. Can’t tell you how much time has been added to my DIY jobs by looking for fallen bots that have dropped and have not reached the floor. Simply amazing, great success on an extraordinary how-to-video. Thanks for uploading this video.

Thank you for producing this great video. I bought a new to me 2004 Lexus ES330. 160K miles, great condition. They did regular oil changes, but did not do the plugs at 120K or the timing belt. I have to work to do now, thanks to your video. You have a heart of a teacher!

The tip about using mono-filament fishing line to keep from loosing the rear plenum bolts gets five stars from me. Really a great idea!

Thank you so much, you just save me hundreds of dollars and now I know just that much more about taking care of my Highlander. Please keep posting more videos.

Your videos are going to be a great help for all the maintenance I have planned for my Gen 2 Solara V6. One small tip. I would recommend cleaning your throttle body before changing your plugs since I've found that they can get dirty from the cleaning process.

Excellent instructional. No useless chatter or commenting. Saved me a lot of time. Five stars.

You did a fantastic job. You didnt go to fast. I was able to understand every move you made. Thank you.

Awesome!!! Great instruction, clear and concise, even us novices got it done! Myself, my husband and my daughter (her car). Your video was so good, that my husband who would rather pay for everything felt confident that we could do it and we did it! My only concern was we couldn't find a third support bar behind the throttle body and low and behold when we removed the plenum and throttle body there wasn't one there. No problem, we got it done. Thank you ! Saved me dollars and I know what parts went in the car. Awesome!

I want to thank and congratulate you on a well done done video and excellent editing along with some nice tips. I am trained in automotive engineering (from way back in the 60's and 70's) and I really appreciate somebody who does things properly and well. Thanks again for a fantastic video.

Thank you so much for this video. I bought the ratcheting flex wrenches and they made the 3 back bolts so much easier. I tightened up the manifold to the engine first and the three back bracket bolts went right back in. Took me 4 hours including cleaning throttle body and replacing intake gasket, pcv valve, ignition coils, and air filter.

Well done. I used your instructions on my 2004 Highlander. Work took ~ 4hrs. Time was extended because I did not have the 12mm ratcheting wrench. I had the 14mm. What ever you do add the ratcheting wrench to your supply list. My supply list was Plugs, PCV, intake gasket. Thanks for the great instructions. - Andy

This guy is so amazing. My favorite part is he tells you what other work you can do while you’re in your car. I’m a total noob so that stuff is cool.

Nicely done video. Patiently done and included a couple of nice tips and tricks too. Cheers

Great instructional video. Yes replacing spark plugs on a V6 Toyota is cumbersome compared to 4 cylinders. Thank you for creating this video which is really helpful.

Thanks alot! I watched a few other videos where they pretty much disassembled half of the car to reach the spark plugs, and I was so frustrated, but after watching your video, I feel much better about the job.

I started the process of removing the air intake and plenum and got stuck on removing the rear bolts on my RX400H. I was messing wit it for hours trying to get my wrench in but had no space for any leverage, Not even one or two clicks. Other videos I've looked at on replacing the rear spark plugs skip the detailed part of removing the rear bolts. I appreciate your video! Gonna grab myself some flex head wratchet wrenches!

Thanks for the feedback! Anti-seize and Di-electric grease are two controversial subjects when changing spark plugs.

Very good terminology, detailed but concise, not forcing things, and lastly, the fishing line!! Outstanding! Keep up posting these excellent diy videos and explaining how things work in other vids. Subscribed!

Thank you for showing that this job can be done without taking off the windshied wipers, wiper motor and cowl tray!

Nice tutorial. The brackets on the passenger side was a beast. Also, I forgot to lose the PVC valve and tubing prior to lifting the air plenum up and out (don't forget) The hose was stuck on the PVC valve. (TIP) use a heat air gun around the hose and the PCV valve will slide off more easier) where the hose meets the PVC valve. The gasket you replaced in the video is not the same for a Toyota Camry 2004, its different. Good think I had the correct gasket with me Everything else looked and is identical. Overall this is a great video. Its the best one I found on youtube.

Wow I've been looking for a how to videos for my son's car. I was looking to have the spark plugs change, but the price range was 200-350. I'm not sure if I could do this but you're video was done step by step and I think I'll give it a try. Thank you.

You sir need to do DIY on every procedure for this car. This was excellent. I am going to have to agree with those who said ....THIS is how you do a DIY video.

thank you of all the videos this is the only one that helped me! Thank You got the tune up done and saved $450

You’re a great wrench! Who would have thought of fishing line? It’s brilliant! Great video!!!

I've purchased the Haynes repair manual. Now that I've found this channel, I'm thinking about using it for kindling

Thank you very much for taking time create this nice help full video...

I have seen many many DIY videos and I am a DIY guy, you have done a fantastic job, I was looking into the details when you were doing things, fabulous mate. great work

Man, now i know why mechanic charge $100 an hour. I had no idea changing plugs was that complicated/hard. Amazing how this dude makes it seem easy. There is no way that I would try to do this type of mechanic work myself.

This guy is better than the rest I've watched. Big thanks men for explaining it in details. Now I feel confident to do it on my Sienna 05.

Crisfix and you are the best mechanic in the world.

I need to replace the pcv valve, clean out the throttle body and the maf sensor. This is the first video I found that actually showed how to do all the things I've needed to be done. Thank you very much. We have the same car, and mine has 345 000 km on it. I want to see how far I can take this car, never had a vehicle go past 500 000 before but I am going to try.

great job explaining everything. the best i have seen

This video helped me out in so many ways You have no idea! This is the best video as the person above was saying on 3.3 MzfZ Toyota engines.

Thank you for this video. I don't have the tools but by watching this video I will purchase the spark plugs, PVC valve and an air filter and have a local mechanic do the work for me. One day I will take a auto repair class so I can start doing basic maintenance on my car.

Thanks for sharing your knowledge. It helped me to replace the spark plugs on a Lexus es300 2003. Gracias !

Thanks for the post. It was really helpful to see what I needed to remove before I could reach the read plugs. Excellent step by step and video quality.

speedkar99, thank you for posting an excellent video. I just replaced my 06 Sienna plugs following your procedure. After seeing that you had removed the strut brace, I knew I had to remove the wiper assembly. It was fairly straight forward. Thanks again. Cheers!

Thank you very much for this video! I just did this whole service on my 2004 Toyota Kluger (Australian Model) of the Highlander. Very informative couple of differences as our cars are right hand drive but for the most part bang on. The most time consuming part for me was the 3 risers on the back of the plenum. Thanks again!

This works perfectly on my 2004 Sienna which have same engine 3MZ-FE. Before finding this video, I tried to change it without removing the manifold but it is impossible, was able to change the front because it was easy. I will try this next weekend. Thanks for this great video.

Thanks! I'm glad that I found your video. Well done and well explained. Ordering the parts right now!

Excellent Video . One of the Best DIY video I have EVER seen . Thank you Please do continue to make more Videos . Just like this one. I LOVE CARS !!! I LOVE CARS MAN !!!

Fantastic video! Thank you for putting in the time to make this video!

Hello Speedkar99, I just want to say thank you for this video. I just did all this to my 05 ES330 and everything is well. Apart from me snapping the evap hose on the bend right at 1:54 (heavy handed) . Mended it a little with a barb and clamps from Home Depot but will be going to the parts store for a replacement tomorrow. Thanks again!

you are excellent ! great video, and technique !!

you are awesome man. Thanks for the detailed description.

That was very detailed! The best video I have seen for Lexus spark plug change. New subscriber

Thank you so much for this vid. I have to do this for my mom's 03 Highlander but didn't know the correct steps to take off the plenum.

Thanks for the idea of masking tape over the intake and fishing line on the bolts!

so excellent ,all videos should be this great

Finally did my spark plugs... thank you for this video, I would love to see you do the injector replacement video as well.. 😊😊😊

Best instructional video for any car I've seen step by step great video

Thanks for the great video and for the fishing line tip, I can use this in a lot of spots!

This aces sir. I may be buying 2005 highlander tomorrow and I was doing some research on what I am sure will be some routine tuneup stuff. This is hardly routine and is a pain in the ass, but I get it. Thank you for the post

Great Video, Great directions , Looking forward to the job now. Saving me a ton . thank you

Very helpful, and demonstrates obvious knowledge and skills. Thank you.

Excellent video, thanks for posting

That fishing line tip is golden!!!

Great video ... Kept me from doing things I shouldn't ... Working on a 2006 Camry 3.3L V6 ... At 5:18, I couldn't get the plenum to clear the two studs because the rear of the plenum was caught under the windshield cowling ... Removed the studs with an E8 Torx socket ... Posting the torques for all plugs, bolts and nuts would be helpful, either in the video or in the overview above ...Thanks again!

Used this video to change the spark plugs and plenum gasket... Used your other video for the timing belt! Want to hear something funny, the hardest part of this entire thing was removing the stupid rear (3) bolts from the intake manifold... WOW!!!! That 14mm on the passenger side was HORRIBLE. It took me a solid hour to get it loose and that is with using the same tools, there was like no room to work! Then it took me another hour to get the bolts back in... Overall I'd say this was more hellish than the timing belt because of those screws, ahhaa. At first I wasn't sure if I should change the spark plugs because they looked ok, but then I thought, everything is already apart just do it. Overall your videos are great!! Thank you again, -Nigel

I like the fishing string idea. Great video!

Thank you SO much for this video! Saved me several hundred in labor charges, and who knows HOW much aggravation! I will say that like an idiot, I failed to follow your advice for tying fishing line to those stupid rear plenum bolts. Here's to hoping 2 out of 3 is enough until I can replace that never-to-be sufficiently-cursed middle bolt!

Again ,thank you so much for your video ,very nice job done.

learn a lot on this video,i like that trick tying up a fishing line on those three stud on the phlenum by the fire wall

All this for 3 Coils and plugs Wow Great Video I'm gonna try this Tom

Thanks for sharing, good video! Toyota jacked up the Camry platform into several other vehicles; including the Highlander. Mine is @183,000 miles, so I replaced the intake gasket too. All parts @1A Auto came to $250 (vs $700 local retail). Plan ahead, order online if you can, it's worth the savings.

Thank you. I am going to change my spark plugs for my Aurion!

Took me 20+ hrs , you need the help of God to accomplish this challenge and the small wrenches size you can find at your local store for the three bolts. They will defiantly help you out. Thanks a lot for this video. I really appreciated !!!

Great Job!!!! I will be studying this video b4 I attempt the job!

For future reference, it is Plenum, not Plenium. Still the best remove and replace video on this site

excellent video, I learn a lot from your teaching. thanks brother.

Nice work transverse engines are a pain in the ass to work on especially V6

Good video - no nonsense, show how it's done. Good job.

thank you so much. your videos help me learn so much about my lexus.

ah well I imagine things get stained from normal wear and tear.anyway great video, it was super relaxing actually. keep up the great work!

Fishing line! never thought of that one. Brilliant

Excellent video, easy to follow instructions Thank You

WONDERFUL video!

Just picked up a 1st gen Highlander V6 and was curious to see the level of difficulty to replace the spark plugs. Excellent video. Very descriptive and helpful. Although plenum is pronounced PLEH-NUM not PLEH-NIUM. Just the grammar ranger in me! haha

Thanks again..another great vid

Great video 👍 , you just got your self a new subscriber .

Thank you for the great video. Extremely helpful.

Just one little comment. The intake plenum is pronounced as "PLE-NUM", not "PLE-NIUM". Otherwise, this is a very helpful DIY guide.

Thank you sir! The 10:13 tip is a lifesaver!

I used to drive a KLDE engined Mazda MX6 and I was able to change the back (right bank) spark plugs by using a long extension and a lot of patience. Is it at all possible to do that here?

Super helpful! thanks for the walkthrough.

Loved it! I was spellbound. Good work. Keep it on...

works for my 2003 lexus es300. everything was exactly the same as in the video.
