Spark Plug Replacement Toyota and Lexus V6

[@russelloppenheimer3970]

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!

[@speedkar99]

I'm glad you enjoyed my video and my video style. No need to present useless information, straight and to the point is all that's needed. Thanks

[@4seeableTV]

Agreed. A well done video and very helpful. I'm going to change out my plugs while I'm in there switching out the knock sensors on my 2000 Avalon. It's funny to watch your gloves go from brand new to totally shredded. = ]

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!!

[@speedkar99]

Glad you found the issue

[@DavidParker-cf2km]

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.

[@speedkar99]

Thanks very much for your kind feedback, torque specs are important 🙄

[@JSo-ff5xs]

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!

[@speedkar99]

Glad it helped

[@speedkar99]

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.

[@jxx1234]

it took me 8 hours including breaks. The 3 bolts behind the intake is a bitch bro... taken them out and putting them back in..

[@charleslao2937]

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.

[@reneanduray7409]

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.

ditto for the fishing line trick!

[@NewShockerGuy]

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!

[@speedkar99]

Thanks I probably have to refer back to this for my Camry too

[@mycatisromeo]

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.

[@jmorazun]

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!

[@bigdavedayday1581]

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

[@mishimposble]

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.

[@CraigNAnderson]

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!

[@andeg8647]

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

[@speedkar99]

Thanks, glad everything worked out for you. Did you have to remove the windshield cowl and wipers to get behind the plenum on the Highlander?

[@PhunkyChikin]

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.

[@speedkar99]

+PhunkyChikin Glad you found it helpful. I bought the ratcheting wrenches just for this job too.

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!

[@speedkar99]

+Tom Ferrin It sure is a life saver!

[@j.santiaguel4337]

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!

[@angelatoler7972]

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!

[@speedkar99]

Awesome!

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.

[@raycrow3718]

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

[@joannacherry5147]

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.

I was thinking about all of the belts, hoses, timing belt kit and the PVC valve, spark plugs and what else should I consider replacing to put the vehicle in optimum condition?

[@speedkar99]

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

[@Healthliving1967]

No,you dont need to remove the plenelum to get to the rear plugs and coils. All i did was remove the actuator on the radiator cap side of the engine and a couple of rubber hoses,and then i removed the throttle body and air intake joiners and you have enough room to change the plugs from both sides by using the right tools-wobble head extension and straight bar extension.

[@speedkar99]

For plastic intake plenum you do. For the older style metal plenum you don't have to remove.

[@NewShockerGuy]

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

[@speedkar99]

I'm glad the video helped you change the plugs! Yes I've heard others have had problems accessing those rear bolts, especially the 14mm one. I didn't seem to have to much of a problem with a ratcheting wrench. I believe loosening the plenum bracket at the bottom of the engine gives you enough play to catch the top bolt in the plenum when putting it back on. The two 12mm behind the throttle body was more easily accessed with a 1/4" ratchet if I recall.

[@CashApp-HelpMeStayAlive]

Lucky for.me the Bolt on the passenger side is Missing LOL . I guess the previous owner left it out so he didnt have to do that again next time he had to remove it. Works rme.

[@paulramxi4415]

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 !!!

[@mindbender7071]

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.

Congrats on the find. Did you get the 3.0 or 3.3L? The 3.3 is harder to change plugs Thanks for the correction.

[@crossphaded]

@@speedkar99 it's a 3.3 AWD. Yeah, not a simple job replacing the plugs! I guess iridiums are the best choice for longevity. You think replacing the coil packs are a good idea on a high mileage Highlander while you're at it?

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 ...

A big thanks for the clear and straight forward instruction on the video!! But, after 150 miles of driving, the check engine, VSC and Trak Off lights appeared on the dash. Car still runs fine.

Those 3 bolts holding the plenum and throttle body are by far the hardest part to remove and reinstall.

Wish you added the torque specs on what you knew of. Certainly for the strut bolts would be helpful. Otherwise, I did get a lot of out this video.

[@petet5213]

Excellent explanation of how to do this job . Plenum nut R & R was the trickiest part no doubt.Highly recommend fishing line or even a colored line attachment, as i blew this off and it necessitated a trip to the hardware store for a replacement bolt. I took the time to write every instruction down ,as told, but got ahead of myself and disconnected one extra brake line that was a puzzle to reconnect, and in order to find it, I left off the MAS causing a christmas tree lighting effect with my idiot lights. A trip to Auto Zone and a code read reminded me all I needed to do was pay closer attention to the game plan and reconnect MAS plug, ( DUH). Iridium spark plugs were expensive enough, but in order to buy the one manifold gasket I needed, I had to purchase a kit with 3 other gaskets I doubt I'll ever use, that cost me close to $ 100. My '04 Highlander with 82Ks gasket actually looked ok, but I just followed directions to replace, but if could have avoided that big extra cost it would have been great.Thanks for excellent video, and thanks to You Tubers I feel I can attempt almost any fix-it job at home , this process is amazing and I am truly grateful for this technology !

[@Ariztid]

That fishing line tip is golden!!!

[@speedkar99]

Yep it saved me

[@whycantijustwatchify]

Holy Cow, this is a pain in the ass. Getting the intake manifold lifted off the studs is also difficult to do. Be careful when removing the coils because I had one of the foam seals fall off and fall down onto the sub-frame which took another 20 minutes to get back. Don't press on the little plastic tabs that hook into the coils either because they break off with the slightest pressure. The 3 bolts holding on the plenum and throttle body on difficult as others have said. The middle one is hardest. Ratchet wrenches are a must and make sure you have a 8mm hex wrench before you start. This video also applies to v6 3.0L toyota camry from 2004. 1mzFE engine Also note that the strut tower on each side is held down by those 2 bolts. I'd recommend torque them ~75ftlbs with blue threadlocker.

[@allenscott1705]

Great job thinking maybe I can do it but you said: It is necessary to remove the plastic intake plenum to reach the rear spark plugs. On the Highlander, Sienna and RX330, the wipers and windshield cowl must be removed to access the rear bolts. Do you have a video for RX330 or wipers and windshield cowl removal? Thanks!

[@speedkar99]

You can try spraying some penetrating oil on it, and limit the extension size on your socket so it doesn't slip. Use a breaker bar or a pipe over the ratchet handle for a bit more leverage. Jerk the bolt loose rather than apply full continuous force, kinda like an impacting action to break the bolt loose. And don't back out the rear plenum bracket bolts all the way so that there isn't any pressure on the 4 Allen bolts.

[@gringowiththelingo1]

Great video. Same process for 2004 RX330?

+Brent Graney yes

You can probably remove the intake and change the plugs in 2-3 hours. A proper throttle body cleaning involves unbolt it from the intake plenum to clean the back side of the throttle plate with TB cleaner and a tooth brush. You'll need a new TB gasket for re-installation.

wooo that was way more involved than changing the plugs on an inline 4, I guess that extra power comes at a price, spotted that nice Snap On wrench, you have arrived bro! lol

[@speedkar99]

+neppy5 Thanks. Yes the V6's are considerably more labor for timing belt valve cover and spark plug changes, but in my opinion worth the power, smoothness and refinement.

[@Mr2pint]

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

[@Konig1985]

fantastic video. Do you advise replacing a perfectly functional water pump during this service?

[@speedkar99]

Thanks. Water pump should be replaced with timing belt service, not spark plugs.

[@unebonnevie]

Always replace the three rear engine/ignition coils as well, even if they are old but still work, since you don't want to go through the crazy process again, if your rear engine coil(s) fail! You can use them as backup for the front ones.

Well done, great job, is it the same process on a 2008 RX350? thank you

[@speedkar99]

+Carmelo Deseta yes

[@oldman3454]

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

[@speedkar99]

Yes! Especially if you are threading in a bolt you can't see!

[@PhattyMcgee]

Hey speedkar99, First off thanks for the video. I'm at the part where you clean the throttle body. Was wondering is it safe to clean throttle body plate with tooth brush while it is on and open like that? and did it move while you were cleaning it?

[@speedkar99]

Yes its safe to clean the TB with it open and on, as long as you have something firm on the gas pedal holding it and it won't accidentally slip and close the plate. Moving the plate manually is not recommended as you could mess up the calibration.

Wow man! What a great video. I have been driving with a cylinder 4 misfire for about a year. The emergency check engine light came on and now I have the parts ready to swap out. Is there anything I can look at to see if the engine has been damaged considerably? I don’t want to get in over my head

[@Livemas-co6kd]

I ended up almost completing the job. I broke three dry rotted hoses

[@marcryptic]

No it is a metal valve very similar to the one in this video. I also picked up the new valve to replace from an auto shop, and it is metal with what looks like red loctite already on the threads. Thank you.

[@NS-hj7km]

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

[@williamlundberg3356]

I like the fishing string idea. Great video!

[@speedkar99]

It helped save time

[@bradpeterson4277]

so excellent ,all videos should be this great

[@charliewrench]

We're you able to clear the check engine light by disconnecting the battery after cleaning the throttlebody? Should I disconnect the battery from the beginning? Awesome video BTW brother!

[@speedkar99]

Yes
