You are such a good man. You are honestly trying to help people save their money.

Dang it, I wish I live in the same area as you are :)... but luckily, you are here with all of us to give honest advices and options on what and what not to fix which helps out a lot. Thanks for posting all these informative videos!

I really appreciate this video -- very useful for our new-to-us family van! Thanks x1,000!!!

Bless you brother! Your expert rundown is awesome and oh so valuable to those able to receive it. Wish that there was such a report for every car I have owned - even better is text report one could stick in their glove box for review. BTW, as to the alternator issue, serpentine belts are SO much better than the old v belts but one change that had to be made to go to them was to the alternator. Engine rotation speed goes up and down each cylinder firing. The alternator is a flywheel and "fights" that. Many older mechanics remember the vibration of V belts due to this. Newer alternators have a rubber shock absorber coupler that solves that. Apparently that coupler can go bad and you get belt chirping (and faster wear on the belt).

I'm in the process of buying a used Toyota van. I'm glad I found your video and possibly saving me thousands of hard earned dollars. 👍🏻

Great info, thanks for really important info on older vehicles. Use to be, 9 years is an ancient car. Now we keep cars 10, 20 years.

Really like the way you explain common issues! Waiting on 2021 sennia you tubes from you!

Thank You for all the outstanding tips before I heads up to the dealership!

Hi AMD! My family got bigger and I bought a Sienna after watching your videos. Nothing scared me because i watch your channel. i always have questions but i scroll through the comments to see the same questions with your replies. I want to say Your community and dealership are very lucky to have you, an honest down to earth man and now your sharing with the world on youtube. Thank you very much God bless you Sir.

I've got an '08 Sienna with almost 200,000 miles and had it since brand new. These vans are unbelievable. I had had very few repairs, ignition coil, rack and pinion, and that is about it.

Hi AMD. I watch you channel very often. We own a 2008 Sienna CE FWD. 160,000 kms. I try to perform all regular maintenance myself. Oil changes, filters, brake pads, light etc myself. Basically all the DYI stuff. Recently I found a coolant leak yikes. Water pump let go. My bother agreed to do the job after watching your video. I also asked him to the radiator because of the age. He was a bit reluctant to change it but I already bought the unit. Well there was a leak in the corner. He also installed all new pulleys and belt. He really appreciated the thoroughness of you videos. Keep up the great work

I am looking at buying a used sienna. These videos are a huge help. Thank you

I'm over the moon with my very clean '05 Sienna Limited Pearl white😍 This is a very quick minivan.. V6 VVT-i with 230hp 6,000 redline. Remove second row seat so now it's a 4 seater✔️. Such a fun vehicle!!

Just looking for used sienna....thanks so much for the information. I know my way around the cars I've owned - but not this one. So valuable to have your expertise! Thank you.

215k on mine. Had to put a radiator on it for your described problem. I got it shut down fast and saved the trans. When I got it at 74k the cams phasers rattled when really cold like below 20F. I switched to synthetic oil and over time they have quieted down. Otherwise very reliable.

Buying a 2008 AWD Sienna, excited! Very good video, thank you! Thumbs up!

My 2004 sienna has 220k miles now , engine is strong and smooth. Runs like a champ.

Our 2005 Sienna is still going strong. Thanks for all of the great information!

I'm at 172,500 2014 Sienna towing pkg with a coolant leak. Good thing I watched this before I had my mechanic look at this. 1) water pump original but leaking 2) coolant plate leaking as shown 3) Coolant cover next to oil filter leaking not on this video 4) plastic thermostat tube cracked 5) leaking radiator. replaced radiator and condenser 6. timing belt looked good after 80k. Mechanic did not want to replace oil seals on crank / cam. Did get new coil packs and spark plugs. New pcv. I had to talk to him for awhile to get him tuned in on issues with this motor. Thanks so much for this video. I'm so happy you took the time to make this.

Thankyou so much for your advice on the 2004 Sienna AWD. I just bought one w/ 200,000 miles and am having the timing belt and water pump changed AND I am going to ask them to add on the other items that you recommended. My friends use their 2004 Siennas as taxis and have already gotten 500,000 miles with it. It's a great van.

Excellent commentary, thank you. I have a 2005 XLE 2WD with about 160k miles and I love it. I stay up to date on all the maintenance and I have never had any trouble. It's a pleasure to drive it long distances. Thank you, keep up the good work. 👍

I'm on my 2nd 04 Sienna. First one got totaled two months after I got it. The replacement is a limited with 152k on it and going strong. Drives nice, rides great, reasonable milage, this thing is loaded, and I dread the day I have to replace it. Hopefully many miles from now. Thanks for the videos!

I'm avoiding ALL THESE PROBLEMS! I still drive my perfect 2002 Sienna XLE. Simplicity and engineering perfection! Cheap repairs and simple electronics. Not a problem in its 170,400 miles. Only two items on the whole car not working: one dashboard light on the left side and the power driver's side mirror. That's it! Paint is perfect. Leather is great. Power doors work like new. The timing belt changed at 85k miles. This model was from 1998 to 2003.

Thank you so much for this video and the information you share! You saved me almost $8000. The 2009 Toyota Sienna I bought had a bad transmission. The day after I bought it, I noticed it made a scratching/scraping noise while idling down from less than 40 mph with no foot on the brake or gas. I searched Google to figure out what was wrong and came across your video. It got my Spidey senses up when you talked about the transmission noise. I called the dealer (Prime Auto, Wichita, KS - Sanjay) and he said it was probably a noise from a minor rub in the brakes and to bring it back and they would fix it. It seemed feasible until I had two reputable local mechanics drive it and they said it was a bad transmission. They said there was no way to know how long it would last before it needed a new one, but the sound was the gears grinding each other. I called the dealer and took the van back and had to politely argue with the dealer that the transmission was bad. He said I took the van to "back alley small town mechanics" who wanted to make money off of me. He also said I was paranoid repeatedly. I told him the other mechanics knew they weren't fixing but only diagnosing the car and that I had researched the issue and found the same information. After much back and forth and gaslighting, I kept pushing about returning the van. He said he could give me $4000 for the van I paid $8000 for a few days prior, since it was now a "trade-in." I was getting very frustrated and told him it either needed a new transmission now or he could take it back and give us our trade-in back. He finally said I could take it to Toyota in Wichita and have them diagnose it and go by what they said. The service advisor at Toyota started describing what the van did and I thought it was from my message. He said it came up when he put in the VIN (this info didn't come up on an AutoCheck :( ) and that the former owner had been advised it needed a new transmission. It took a few more days to get our trade back and get the title and payment through, but I am so thankful for this video. I listened to my gut and checked it out after finding this information and stood my ground! Thank you for the information and for giving me confidence in the facts!

Fantastic video! This series will serve a lot of people. BRAVO BRO!!

Thanks for all this information, I'm currently looking for a good used Sienna and your videos so helpful!

Excellent video, very useful, I have to watch this a couple of times more to learn about the newly purchased 2005 Sienna, thanks.

Had a 2005 Sienna. It had 230K miles December 2020 and engine was pristine. Did synthetic Mobil One Oil changes every 5K. By then I had to replace a cracked thermostat cover (black plastic), the shifter cable, alternator, ac compressor (my mechanic friend, I do not do AC) and starter motor. My mechanic friend did 2 timing belts and I did spark plugs twice. But it ran like new. The transmission another conversation. Sadly I never heard of transmission flushes and by the time had the dealer do the 1st one at 126k miles damage had already occurred. If my son had not totaled it in a crash I was looking at a new transmission. Great vehicle and yes I would have put a brand new transmission in it if it had not been totaled.

Thanks for the Info about the Engine & Tranny . I'm actually glad I found this video today. I bought a 2008 Sienna XLE with 139k miles earlier today this Sunday. Now I'm gonna keep an eye on all the issues you're talking about :) Keep up the good work & just letting you know that you gained one more subscriber :) Thanks Again :)

Man I wish you were my mechanic

Another great video thanks. Although you explained things perfectly, all I kept hearing is 'don't own an automatic' 'manual (standard transmission) for the win'

I wish everyone made videos like yours! So much good information, and you are very knowledgeable. Much appreciated. And, the oil lines, yeah, replace both of those, and the ticking on start up, yeah, replaced the engine ... after the variable valve actuator threw a few bolts into the motor 6k for a used one, but running good at 250k 10 years later (2008 highlander)

Thank You, for all your wisdom and knowledge!

I totally agreed with you about the oil cooler lines for the G2-FE V6 engine for the Sienna. My 2007 V6 Sienna and my 2010 V6 Venza both oil cooler lines broke at exactly 100K. My Sienna oil cooler line was replaced by the Toyota Dealership and cost me $1200 while my 2010 Venza cooler line was replaced by a local gas station three years later for $375.

Thanks for this, very informative and useful for me. I'm looking at an '05 right now. I just subscribed, keep it up king. Glad I found this

07 owner. Only had to replace the water pump so far. Looked too difficult for me. Wish the dealer would have mentioned the timing belt while it was being done. It still runs great. New subscriber love your videos God bless

Wished this video came out a couples months earlier. Very informative. Thanks!

Great and very informative, even for the owners. My wife calls ours a “Tank”. Because the beast is unstoppable in the winter on proper winter tires. As a ten year owner myself of 2008 AWD I can tell you the following: the 3.5 is pretty awesome and super powerful-ours tows 14” enclosed trailer with ease. Pop up behind it doesn’t even gets noticed. I changed a water pump myself one afternoon at 145,000km and it’s not hard at all. I changed all spark plugs preventatively with recommended platinum tipped and won’t have to worry about them for the rest of its life. I changed to an updated trans oil cooler lines that are all metal because our van tows a lot. I replaced the rubber elbow on the upper oil line to an updated part but sadly I didn’t go for an all solid metal tube at a time. Our van doesn’t leak a drop of oil from anywhere, period. Not even from trans or the tiniest transfer box ever, that it has for the rear prop shaft. I fixed/rebuild a squeaking alternator and let me tell you, those suckers are NOT easy to remove from engine-you will be draining the coolant and dropping the radiator slightly. It’s that bad. And that’s about it really. One other thing is a steering rack-not sure if mine was replaced before but the current one has been leaking from pass side outer seal into the rubber boot. I treated the oil with rubber rejuvenation fluid and it’s been unchanged for the last 7 years now. I am of the same opinion that’s if it’s too much work and the part is expensive, let it work for now and let it develop. Oh yes and last but not least, are those stupid tensioner rollers. They absolutely WILL drive you insane with noise and even OEM Toyota part will star squeaking eventually but usually only when it’s cold out. You can only change two of them because the actual tensioner roller is slightly different and isn’t sold separately like the other position #2 rollers.

Great channel and information - looking forward to Part 2!

As an owner of a 2007 Sienna with 190,000 miles you were right on with the issues affecting the Sienna. My biggest one is the alternator. I wished you made this video before I had this issue. I replaced the water pump, belt tensioner, two pulleys, crankshaft pulley, and power steering pump and it ended up being a bad alternator!!! It was a big headache but I can't be mad because this van will last a long time and I should be good for another 100,000 miles as I try to hit my goal of 300,000 miles. I will replace my radiator this spring to avoid any transmission problems.

Oh man, I’m about to buy a sienna so this video is a blessing. I wish it was a PDF list I can take to a test drive. 😂 Thank you so much!!!

This video was incredibly informative and easy to understand, thank you very much!

I have an 06 Sienna I bought with 110,000 miles on it. Now has 240,000 and still going strong. Would be another in a heartbeat. Great van!

Your videos help me bought 06 Sienna LE w/ 220kmi for $3k today. It has god awful oil leaks everywhere but it drive and looks fairly new. Thank you.

Suck a super helpful, clear and through information download. This vid was crucial for choosing make/model/year for us and having a list of what to look for and bargain with for buying our used minivan. Thanks!

After watching all your videos, I gather the best years are 2007-2010.

I have a 04 Sienna, 187000 miles, runs great, no leaks.

Thank you for this valuable information ! Preventive maintence can go a long way I have a 06 Sienna now with just over 300k which I am happy with

Thanks as always for sharing your incredible knowledge with us all. I would be most grateful if you ever did a rack and pinion swap on a 2008 Sienna. I’ve been avoiding it for a while but know it’s in my future. I knocked out the plugs with your other video so thanks for that one too! God bless.

Dam one of the best informative videos ive seen, Thank you for spending the time !!

May god bless you too. Thank you for doing these videos. Very informative.

Outstanding video, thank you! We purchased a new 2005 Sienna back in the day and it served us well for 10 years and nearly 200k miles. Only issues we ever had were the radiator at ~150k (easy diy fix) and what turned out to be a bad computer that was draining the battery (relatively $$ troubleshooting by a trusted mechanic and not diy). Overall a great purchase though. Considering similar circa Siennas for some of the kids now that they are starting to drive and really appreciate all the information, although after watching some of the 4-Runner videos am thing that might be a better option.

wow, suuuuper helpful video. I'm looking for this car, and now I know to spend the extra month on a '08, '09 or '10, THANK YOU!!!!

very nice, thank you. I am considering a 2005 AWD with 198K, very helpful...

Hello AMD !!! first of all I want to thank you for responding to my corolla and es330 questions. I recently purchased a 2007 Toyota Sienna LE 2wd with 130,000 miles. The issue is that it vibrates upon acceleration especially at heavy acceleration. Like always thank you and God Bless You!!!

Was looking for other info but decided to slow down and watch the video. Glad I did! Had found some leakage at the transaxle split line. Just tightened the bolts and keep my fingers crossed. Unfortunately found some leakage on the power steering pump, and as you say, it's really the timing cover. Engine out to fix...Oh well, that's life. Anyway, thanks for the vid!

Been waiting for this!

Thank you, I get lots of experience. Because I didn't know that about this car anything I am now running

Great advice as usual!! Thx

Mercy, this video reminded me of a joke a friend, who was a classic MG sports car enthusiast & restorer told me, "Do you know why the British never made a watch?, they never figured out how to make it leak oil."

Your video was very educational and useful,tnku

Hi, thanks for the video. It would have been nice to see the parts you are discussing in your presentation. Helpful for us cook book types. . .

Thanks for your expertise!

Thank you so much for sharing your expertise, Bro....

I have 2004 with 3 3 engine had vale covers gasket s. Replace had readator replace in 2014 has 337000 miles still dependable runs and drives good best driving and riding vehicle that i own i love it

Many thanks for your video AMD. I have an 05 with 79k miles and aside from fluid/filter changes, I have replaced (DIY) some very common issues with these vans simply due to age, not mileage, including (1) Sliding door hinges on both sides. When the door starts to sag due to worn hinges, the motor has to work extra hard and eventually the cables snap. Change the hinges once the sliding problem begins and the motors/cables are saved. (2) Sliding door lock motor actuators on both sides. Use OEM only. The aftermarket ones will not last. (3) Spark plugs on cylinders 2, 4, and 6. Got a misfire on 4 and replaced the 3 easy plugs. I'll tackle cylinders 1, 3, and 5 soon and per your advice, will replace those ignition coils at the same time. (4) Replaced the radiator/transmission cooler and hoses per your advice. I had no leaks, but combined the job with a full transmission fluid flush. (5) Front brake rotors and pads. These vans are heavy and the brakes barely adequate. Some people swap in the front calipers and rotors from 2011+ models (direct drop in if you have 17" wheels) for more bite. The 2011+ calipers are dual piston, the pads larger, and the rotors are 1" larger too. (6) AC compressor and condenser due to age. Compressor seized. (7) Timing belt, drive belts, and water pump due to age. Paid the dealer to do this. (8) Inner/outer tie rods on both sides. Boot broke and grease spilled out. No problems with the steering rack (yet). For any prospective buyers, know that these are older vehicles and work needs to be done. You have to expect this with any older vehicle. But if you take care of the van, it'll treat you right in return.

Have a 09 with 150 K. Minimal issues going strong!

Very helpful. Thanks!

Thanks very much for the informations!!!!!

Good job Sir. Good content!

Absolutely God send thank you for your wisdom

Love ur videos from New York

thanks so much for the vids , i really appreciate you ! btw ive had 8 toyota vans from 84-2010...

Thank you for doing god's work here

Great Video. Very thorough. You nailed it. I have an 06 that when you start squeals unless you turn the key to Accessory position for few seconds and then start, it does not squeal. I am thinking it's the the alternator...

2004 with 205,000 miles. Uses zero oil. None! Looks like honey after 5,000 miles. Hated the idea of getting a mini-van when the kids were small. I'm driving this until the wheels fall off! Still looks great and is nice on the road. Best vehicle I have ever had. Replaced a flex pipe and struts. That's it.

May the Lord bless you and keep you as well

one of my radiator cooler lines blew off on the road, i JBwelded back on and it has worked great since

This guy would be a good ass service advisor

Good video but I think it will take it to another level I think when you talk about some of the parts or ideas it be very helpful if you would just show pictures of them while talking but I do know its hard it time consuming when putting the video together but this video is pretty good 👍

Hi! Great vid! Do you plan on doing a video on the 98-03 Sienna? Is there the same transmission cooling line into the radiator concern on these years? I'm buying a 1998 one with 215k miles from a family member who took care of it. Everything runs fine but I'd like it to continue like that! 😄

Thank you sir! I was thinking of buying a sienna but I think I'll just keep my OG Nissan Quest.

Thank you good sir

Thank you for the video. I am planning on buying one tomorrow from a local 3rd party dealer-2006 Sienna LE. It has some 200,00 miles. I asked the dealer if the water pump was already replaced. Am told yes. But I am skeptical on it-no record on carfax. But hopefully the service records will show if I add it on Toyota Owners (if the services were done by Toyota dealers). I am planning in replacing everything mentioned (if not reflected on service and history reports) plus oil change, transmission/brake fluid flush and refill, except for the transmission components. Those would probably be around $2,000 of major service. 😅

This is such great content! Wish you were based in the San Francisco, CA area!

So happy to have some one like you helping out the majority of us who lack the knowledge but want to keep our vehicles reliable and affordable. I have a 2007 sienna 147,XXX with slight cold start rattle and possible slight tick heard when the engine cover off but NO codes (P0014, P0015, P0024, P0025, P0017, or P0018). 2007 is the worst year for sienna so I guess its unlikely to get to 500,000 miles without taking the engine out for repairs? How many miles should I expect before it needs the engine out or replaced? I am guessing I should not have the engine taken out for T-SB-0094-09 until the sounds get worse AND I get some code for it...? If I do full synthetic Mobil 1 high mileage oil changes at 2,500 miles instead of 5,000 miles will that be enough to stop the progression of the lack of oil pressure to vvti gear or not matter? So glad I to have a honest master toyota mechanic to watch like you. May the Lord bless you and keep you!

I have an 07 torago utilma v6 3.5 (3rd gen toyota previa) only issue been waterpump 225000km 7 leather seats captain chairs electric doors electric rear seats 2 sunroofs has the same running gear as the 3.5 sienna been a very reliable van

Toyota Sienna is the most reliable vehicle, I trade mine every year or 8000 mi and never had issues but the regular recalls.

I've had a 2004 Sienna since 2012 (now 2022) and driven it 200k KM's to 360K KM's. We've also had the coolant plate leak, and have recently noticed pink coolant from rear bank of engine. It has stopped in the last 6 months but not sure how long it will last without having to replace head gasket (which I won't do because of age). Thanks for the informative videos.

Father in law 2008 that we always borrowed for our Disney trips had the plastic transmission link break just after we got to Disney World and the transmission would only go into Reverse or Park, good thing there is a full service garage and rentals at WDW!

I had a 2008 sienna over 365k with same engine and transmission hit a curb with right rear wheel screwed up alignment and it was eating tires hated to see it go it was part of the family

Good information

Thanks for the video, it was very informative. When is the next part coming out?

The 3.3 l also has a an interesting coolant leak coming from a plate next to the oil filter stem. Easy fix, just take of and apply new sealant, but be warned, you will be changing your coolant.

Thank you! Very educational. What if that you take camera and show on real car. I mean as master and students on operation. I have a question. Among the years which you have covered on this video, which year do you recommend to buy?

Good vid !

Untrained ear can't tell the noise I'm listening for in that really short clip or that background noise you've added to the video. Drat. Good info.

Thx very much!

شكرا جزيلا على الترجمه Thank alot for transtoin Ples part 2 make translation in Arabic plessss
