Thanks for the video my friend. It helped a lot. There are a couple of extra things I did to make it even easier. The first one is to remove the PCV hose (and PCV valve). That will give you more access to remove and replace the left spark plug. Also, another trick to get better access is to put the car in PARK without the handbrake on with the driver's side door open. Stand by the driver's side door, holding the door frame and rock the car back and forth. When the car is rocked forward in PARK, the back of the engine moves up a few inches, but when you rock it backwards the back of the engine moves back down.when you rock it as far forward as you can, quickly put the parking brake on and the back of the engine will stay up, giving you a few extra inches of access to all the rear plugs. Thanks again!
Muchas gracias por este video que enseñó La verdad que sí yo tome en cuenta su consejos y todo lo que enseña en este vídeo y la verdad que es fácil y rápido miré varios videos para poder hacer mi trabajo y la verdad Este es el mejor el mejor el mejor
"Hey, where did you get that tool from...Pearl Harbor?" HAHAHA!! Seriously, great video. I had to do this same approach to do wires, plugs, and coil on a 2004 Ford Freestar.
ILLUMINATI violante jajaaa..Pues que bueno que no lo hiciste y que te sirvió este vídeo. Y gracias también a ti por tu comentario. Saludos cordiales :D
Great video!!! I wasn't able to remove the bolt holding the bracket to the rear of the engine, but was still able to get the last spark plug out. It would have been faster if the bolt had come out, but still got the job done. Thanks for posting this video. Your approach to this job was much simpler than the ways shown in other UA-cam videos.
Excellent work, I was once a dealer mechanic many years ago, for a year, and later completed a degree in electrical engineering at the University of Virginia. As I watched I thought about all the work I would have to do if I wanted to do the same or similar thing for the Hispanic community (and I had spanish in high school). This video makes what appears to be a daunting task a great deal easier- thanks very much for your generous and selfless effort!
Thanks Greg... That is the purpose of this video, to help others. If God has given you a gift, share it with others and He will bless you Thanks for your comment.
Big thank you. I had to change the PCV valve on a 2005 Sienna. Just couldn't get to it and its other connection. Your tear down was very helpful in getting to the valve. Muchas Gracias... Now I also know how to tackle the plugs :)
I have changed the plugs on my 2003 Sienna twice now following these directions. It's not as bad as it might seem. Definitely follow this man's suggestions and remove the wiper cowl. (You don't need to disconnect the wiper motor, btw; the cord is long enough that when you remove the cowl you can just leave it connected and lean the wiper cowl assembly against the driver's side of the van.) Then, also remove the rectangular plastic chute that leads to the blower wheel, on the passenger side; there are three nuts holding it on; removing this will really give you great access to the rear two plugs closest to the passenger side. (Bank 1, cylinders 1 and 3). Then remove the pcv valve. (19 mm wrench). Now, this may be the most important suggestion of all: Get a good flat magnetic light that you can stick to the firewall, to give you light back there. I got one of these at walmart for $10, and it made the job very easy. Once you have done all of this just move patiently and slowly, and be careful not to break the plug clips that connect to the ignition coils. Be gentle with them. The little locking mechanism on the clip sometimes does not want to leg go; I have used a very small flat head screwdriver to slightly lift the mechanism a little higher as I simultaneously pull the connector off the coil. Also, I have used longer needle nose pliers to gently depress the unlocking mechanism on the clip, which works very well, especially on the rear ones which are harder to reach. This works better than simply trying to release the clip with your fingers, since it gets more leverage. Once disconnected, the rear ignition coils can be a little tricky to get out, because of wires and the pcv hose getting in the way; however be patient and maneuver them and they will come out of the spark plug tube without too much trouble. Be careful not to lose the round rubber grommet that is attached to the ignition coil; they have a tendency to fall off; hold on to them as you are removing the coil, so that it doesn't fall off. I always do one plug at a time. Removing and replacing the spark plugs just requires a 3/8" socket with a variety of extensions and swivels, nothing fancy. The combination of these that works on one rear plug may not work on the other rear plugs; the angles are different; you just have to experiment with each one to find the combination of extensions and swivels that works for each one. The plugs can be somewhat seized in there; on my most recent job the plugs had been in there for 220k miles, and a couple of them were not easy to turn. Definitely tape your sparkplug socket and extensions together, so that they don't get separated when you go to pull out the plug. That is important. I put a little anti seize on the threads of the new plugs. To avoid cross threading, I put the new plugs in with just the extension attached (not the wratchet), and turn with my fingers to get the new plug properly threaded in; then once I can't turn any more with just my fingers, I use the wratchet to tighten the plug down, but not too hard. Good luck! St. Joseph pray for us!
This is thinking outside the box at its finest. Good video! I can't understand why Toyota would put out a flawed design like this. Moving the engine forward three or four inches would have been an easy fix as would reversing the engine position to put the intake manifold on the front of the engine. Toyota needs to assemble a few creative mechanics like yourself to give them pointers on how to build a better vehicle.
Thanks for the video. I noticed that there were many techniques in other videos but I found that your video was the easiest. I purchased a similar ratchet which made the job that much easier. Thanks again, your short video saved me tons of time and money.
Not to bad for a bi-lingual video. You missed a few translation in gringo. :-) My 99 sienna has about 4 vacuum hoses on the left that I didn't see on yours. Also watched another video about rocking the vehicle in park back and forth a few times and then locking the emergency brake in the far forward position push which allows the engine to be tilted just an inch or two to give you more forward room. Thanks for including us gringo's. :-)
This was a really helpful video. Thank you. I changed my plugs today for the first time. It went well, took about three hours. Removing the wiper cowl is very helpful -- if you do that, you can definitely reach the three rear plugs without removing the intake manifold, at least on my 2001 Sienna. The most difficult aspect is removing the plugs from the ignition coil/spark plug connectors that go down the tubes - on the rear plugs, you can't get them out without removing the plugs. I had to be very careful pressing down the little plastic thing that locks the plug to the connector, because it could easily break. Just go very slowly and patiently with that and you will get it; it's better to go slow than to break one of those. Also, be sure to have a few different size ratchet extensions on hand. I had a ratchet with a head that pivots forward and back that was extremelyl helpful. On the rear plug closest to passenger side, I took the opportunity to remove the pcv valve while I was at it - removing it will give you more room to work, and then you can put a new pcv valve in (it keeps your engine from getting sludged).
I will attempt this soon. How do I go about disconnecting the connectors that go down the tubes ? You mentioned pressing down the little plastic thing that locks the plug to the connector. Is there a 'button' ? I thought that I could just pull it off I'm glad I read this. Also when I heard him thanks the Lord it brought a smile to my face too.
Thank You for yours comments amigos.. I made this video to help others. Thes vehicle is very complicated to do the sparks job. (I ran out of memory when I made it.)
After removing the plastic cover, you can easily reach the spark plugs 3 and 5 that are in the back with a wrench extension, or through the small opening in the front with a short wrench. :)
Thanks. I replaced Spark plug 5 and its ignition coil. However, Spark plug 4 seems hard to reach. I tried to remove wiper assembly but stuck. I am not sure how to remove wiper out from its base, so that i can remove the whole assembly.
Thank you again Brother. Thank you Jesus... and I don't mean Hay zeuss either. :-) I finally got to change my plugs. Just wish I was able to change my own timing belt, water pump, belt tensioner, idler pulley's, cam seals and crank seal myself. I didn't use a specialized ratchet I just had to use different extension's to get them in and out. Just couldn't torque the rear ones at all. Thanks again for helping us gringo's.
Saw the factory recommended procedure so I was ready to faged-about-it. Then I saw this and went ahead and did the procedure with no issues. FYI I found that there was no need to move the manifold bracket for the passenger side plug as described in the Spanish version at about 3:30. It was tight getting the plug wire and boot out but wiggled it clear and was good to go. Thanks for sharing with the motor-heads of the world.
Lol I am gonna need a few more extensions! Thanks for showing this. I need to do this on my van. Putting in some good Iridium plugs so they will hopefully last a VERY long time!
Just a heads-up for anyone who--like me--still drives one of these faithful old vans (mine is a '99 :~). I watched this video yesterday and changed my plugs last night. NOTE--You do NOT need to remove the manifold or throttle body as shown in other videos! A. As you see, the front three plugs are simply enough--remove the cover, electrical connections, and coils, and replace. (Now would be a good time to point out I am a DIY accountant, not a mechanic. So I don't know what half this stuff is called.) I broke one of the plastic clips on the L-shaped electrical connectors in front of the plugs. It would probably stay in place due to the plug's tension alone, but after I was done and reconnected it, I used two nylon cable ties to ensure it stays in place. B. Plug 4 (back-right). This was actually my hardest. For the back three plugs, if you don't want to remove the manifold, etc., you WILL need a flexible/jointed ratchet or swivel extension. I used various combinations of a regular ratchet, 4-inch extension, 6-inch extension, and a swivel join. My ratchet wrench itself was not jointed, but others recommend one, esp. for this plug. If you don't have (and can't get) a wrench or joint that swivels or flexes, you will need to remove more parts. Anyway, I got my plug out alright, but once I got the new one in, I couldn't tighten it very easily since my ratchet handle kept hitting various parts around the throttle body. A shorter (5- or 6-inch) ratchet would have been ideal. I got it snug, but certainly couldn't torque it like I did the others. C. Plug 5 (back-middle). This was the easiest of the back three to access. I left the cap/coil off #4, then pulled the cap/coil off #5. The angle gave more room for the ratchet on this one. D. Plug 6 (back-left). I basically did what 1uncion1 does here. It takes a fair bit of extra work, but as long as you're careful, it goes fairly quickly and without complication. --Nothing like removing everything AutosNCars removes in their video. Once you have removed the wipers, vents, and the big tray in front of the firewall/windshield, accessing #6 is fairly easy. NOTE: on my model I did NOT have to move or push back the metal bracket to which 1uncion1 referred. What I DID have to do was pull the caps/coils back off plugs #4 and #5, then pull #6 and all three wires out of my way. I also removed one small electrical connector up near the firewall, next to a larger connector that I left alone. Once I did that, I was able to use my extension and swivel to easily remove and replace the sixth plug. This was the first time I have replaced the plugs in my 1999 Sienna. The job--including a few back-tracks--took a total of roughly 3 hours. --Certainly well-worth the $200 - $300 in savings over going to a mechanic. If you read this comment in the next month or so and have a question, feel free to ask. Much past a month, I will have forgotten what I did and be of little help! :~)
kentcan Hi there and thank you for your comment, it is very helpful. I am going to attempt to replace the plugs on my 01 sienna. Could you tell me what specific tools you would reccomend? You mention flexible/jointed ratchet but I just want to make sure I get the right size and have all the correct tools before I make the attempt. Thanks for your time!
Derek Reid Again, mine is a '99 so I can't promise everything is identical, but I guess they're supposed to be the same model. I used basic hand tools plus a ratchet set--metric I believe. Some of the items used include: Flathead screw driver (prying off the windshield wiper caps). Pliers (moving pipe clamps). Allen wrench or hex key for removing the very first plastic cover (sorry, I don't know the size). 3/8 ratchet set Spark plug socket for your wrench--I believe it is 5/8". TIP: you will really want a magnet of some kind, or a rubber-lined socket. The back plugs are nearly impossible to get out. I loosened mine with the socket, but then had to use a telescoping pen magnet to drag the plugs out. A magnetized socket would have been ideal. Finally, there a couple plastic retention clips (?) that have to be removed as part of the windshield wiper housing disassembly. You could probably just use the tip of your screwdriver like I did, but all the plastic on these old vans is getting brittle. Your best tool would be a flat nail punch. If your clips are like mine, you punch the middle pin IN, then pull the clip out, then pull the pin back out before reinserting and reinstalling. Two weeks after the job, my 16-year-old van is purring like a kitten once again. :~)
I did this recently on a 1998 sienna. Your video helped out a lot. I did everything you said to do and replaced all plugs in an hour and half. Thanks for making the video.
Gracias mi Amigo tu Video y tu orientacion Fueron de Mucha Ayuda ya que yo tengo una Toyota Sienna del 2001 y Necesitaba Hacer ese Tipo de Reparacion. Gracias.
Take me two hrs. to do It. But I save $400 Dealer job. Me tomó dos horas para hacer el trabajo pero ahorré 400 dls. si el dealer lo hiciera.... Dale Like si te sirvió. :D LIKE....
Yo se las cambie a la mia y si quitar nada de eso que tu estas mostrando en el video pero bueno si ayuda de mucho tienes mas espacio para trabajar pero en fien solo es de paciencia y un poco de maña para poder sacarlas
Que bonito era cuando le cambiaba los spark plugs a mi 93 honda Accord los carros de ahora son un desmadre me cobran $400 por cambiar unas bujillas que cuestan $6 lol
Muy bueno. Gracias. Me podrías decir cómo es el nombre en inglés de el rache articulado ? A demás es posible probar las bobinas ( las que van sobre las bujías) desconectando sus terminales?
Oye y para cambiar el empaque de la tapa si debería de quitar el Intec de admisión o crees que se podría hacer así también? Yo tengo una del 2001 y necesito cambiar los empaques
It took me two hours to replace my 2000 Sienna too, to me it's a very stupid design by Toyota. Next time just buy a 4 cylinder so it's much easier to maintain, plus modern 4 cylinder engine do have much more horsepower than many years ago.
Thanks for your help. I did manage to change plugs but unable to place bolt back in on that support bracket in back that you suggested to push back. The engine weight shifted down so must I use that bracket? Please let me know, thanks.
Thanks for the video my friend. It helped a lot. There are a couple of extra things I did to make it even easier.
The first one is to remove the PCV hose (and PCV valve). That will give you more access to remove and replace the left spark plug.
Also, another trick to get better access is to put the car in PARK without the handbrake on with the driver's side door open. Stand by the driver's side door, holding the door frame and rock the car back and forth. When the car is rocked forward in PARK, the back of the engine moves up a few inches, but when you rock it backwards the back of the engine moves back down.when you rock it as far forward as you can, quickly put the parking brake on and the back of the engine will stay up, giving you a few extra inches of access to all the rear plugs.

Just a heads-up for anyone who--like me--still drives one of these faithful old vans (mine is a '99 :~). I watched this video yesterday and changed my plugs last night. NOTE--You do NOT need to remove the manifold or throttle body as shown in other videos!
A. As you see, the front three plugs are simply enough--remove the cover, electrical connections, and coils, and replace. (Now would be a good time to point out I am a DIY accountant, not a mechanic. So I don't know what half this stuff is called.) I broke one of the plastic clips on the L-shaped electrical connectors in front of the plugs. It would probably stay in place due to the plug's tension alone, but after I was done and reconnected it, I used two nylon cable ties to ensure it stays in place.
B. Plug 4 (back-right). This was actually my hardest. For the back three plugs, if you don't want to remove the manifold, etc., you WILL need a flexible/jointed ratchet or swivel extension. I used various combinations of a regular ratchet, 4-inch extension, 6-inch extension, and a swivel join. My ratchet wrench itself was not jointed, but others recommend one, esp. for this plug. If you don't have (and can't get) a wrench or joint that swivels or flexes, you will need to remove more parts. Anyway, I got my plug out alright, but once I got the new one in, I couldn't tighten it very easily since my ratchet handle kept hitting various parts around the throttle body. A shorter (5- or 6-inch) ratchet would have been ideal. I got it snug, but certainly couldn't torque it like I did the others.
C. Plug 5 (back-middle). This was the easiest of the back three to access. I left the cap/coil off #4, then pulled the cap/coil off #5. The angle gave more room for the ratchet on this one.
D. Plug 6 (back-left). I basically did what 1uncion1 does here. It takes a fair bit of extra work, but as long as you're careful, it goes fairly quickly and without complication. --Nothing like removing everything AutosNCars removes in their video. Once you have removed the wipers, vents, and the big tray in front of the firewall/windshield, accessing #6 is fairly easy. NOTE: on my model I did NOT have to move or push back the metal bracket to which 1uncion1 referred.

I also removed one small electrical connector up near the firewall, next to a larger connector that I left alone. Once I did that, I was able to use my extension and swivel to easily remove and replace the sixth plug.
This was the first time I have replaced the plugs in my 1999 Sienna. The job--including a few back-tracks--took a total of roughly 3 hours. --Certainly well-worth the $200 - $300 in savings over going to a mechanic. If you read this comment in the next month or so and have a question, feel free to ask. Much past a month, I will have forgotten what I did and be of little help! :~)
kentcan Hi there and thank you for your comment, it is very helpful. I am going to attempt to replace the plugs on my 01 sienna. Could you tell me what specific tools you would reccomend?

3/8 ratchet set
Spark plug socket for your wrench--I believe it is 5/8". TIP: you will really want a magnet of some kind, or a rubber-lined socket. The back plugs are nearly impossible to get out. I loosened mine with the socket, but then had to use a telescoping pen magnet to drag the plugs out. A magnetized socket would have been ideal.
Finally, there a couple plastic retention clips (?) that have to be removed as part of the windshield wiper housing disassembly. You could probably just use the tip of your screwdriver like I did, but all the plastic on these old vans is getting brittle. Your best tool would be a flat nail punch. If your clips are like mine, you punch the middle pin IN, then pull the clip out, then pull the pin back out before reinserting and reinstalling.
Two weeks after the job, my 16-year-old van is purring like a kitten once again. :~)
I did this recently on a 1998 sienna. Your video helped out a lot. I did everything you said to do and replaced all plugs in an hour and half. Thanks for making the video.
Your technique is really easy to replace the spark plugs! And your information on the HF 3/8 in. Drive Dual Flex Ratchet is very helpful! Thank you!

gracias bendiciones
God bless you!!!
Great video, i think i can do mine too.
It took me two hours to replace my 2000 Sienna too, to me it's a very stupid design by Toyota. Next time just buy a 4 cylinder so it's much easier to maintain, plus modern 4 cylinder engine do have much more horsepower than many years ago.
Buenas tardes amigo
It would have helped if you showed the video of you removing the two that you said was easy
I did the same thing yesterday, but I didn't remove anything just using swevel socket and extension s
Como es el tornillo que va tornillo ese barrita se que mover para quitar la bujilla
Thanks for your help. I did manage to change plugs but unable to place bolt back in on that support bracket in back that you suggested to push back. The engine weight shifted down so must I use that bracket? Please let me know, thanks.
My van is the same without the bolt, but nothing wrong has happened with it yet. So I think your car will be fine without the bolt...
+1uncion1 My van has been doing fine, and it's already been 3 years :D
Thank you!
Thank you!
I am having trouble removing the windshield wipers! It doesn’t separate
🙏
thank YOU, grazie,
