2005 toyota sienna 3mzfe bad leaking from inner water outlet
HTML-код
- Опубликовано: 25 авг 2024
- If you have a leak between the engine and transmission it means that you may have a leak from the inner outlet or the inner water hose. This engine is from 2004 and 2005 Lexus or Toyota v6 with the 3mzfe also similar to the 1mzfe.

This was one of the best videos for a pretty major repair that I have ever seen. I really had trouble with the 14mm bracket bolt at the back of the upper intake manifold. I eventually had to loosen up the bracket from below which allowed enough room to take off the power steering clamp and then pivot the manifold towards the front of the car and then take out the bolt (8 hours total). Before I put it back together I got out the grinder and made some improvements to the bracket...I removed the "hook" at the top and ground off the sides so that now I can get a wrench on it from the top or either side. Also, I want to emphasize your point about not over-torquing the 10mm bolts. I broke one off on the water channel cover and had to drill it out and tap it (another 8 hours). After that I replaced all of the bolts when I put it back together (the second time). While I had it all apart, I also replaced the manifold gaskets, plugs and coils. Also had to replace all of the coil connectors since the plastic had become so brittle (there are good u-tube videos on this also). This is our work van and has 261,000 on it and still going strong.
I have no experience but it looks like just removing bolts n clamps! 8 hours!? Then it gonna take me 20 hours. I have this exact leak n im sure its the same reason same spot exactly.
Suggestion on this job (removing upper intake manifold): remove the windshield wipers / wiper assembly and the pan it sits in. SOOOO much more room (you can see in the video that it is removed); still not necessarily easy, but huge time savings due to more space in reaching the bolt on the backside of the air intake manifold. I was replacing the valve cover gaskets this weekend - fought it for a while then it came together quickly. I also took apart the air intake (two pieces) between the filter box and the upper air intake; it was much easier to get to the two vertical support bracket bolts on the backside.
Thanks for the video. Finished putting my '05 all back together last weekend. No more leaks. It took FOREVER to clean up the coolant valley. Lots of scraping, scrubbing, standing on my head, cussing, etc. Decided to replace intake gaskets, and rear spark plugs while I was in there. I live in a very dusty area in Arizona, and would advise stuffing the intakes with towels to avoid getting debris (or dropped bolts/nuts) down the intake.
Oops
Hey I got to do the same thing, how long did it take you approximately? Greetings from azy
My 2005 Toyota Sienna leaking from this exact spot too. Very helpful video. Thank you.
ASE Certified Tech here, so for the bottom plate no gasket is available, however for BOTH lower intake AND upper plenum, gaskets ARE available! Do yourselves a BIG favor and put new ones on! Also super easy to replace spark plugs with upper plenum off so that would be the time to replace them too. Iridium ones (should) be used since they are hard to replace, sound advice :)
@Bryan V. I'm trying to familiarize myself with this strange looking engine as I have to change the spark plugs and plan on replacing all the gaskets, pcv valves & possibly the wiring Harness for both knock sensors to kill all birds with the same stones. What exactly are you calling the "bottom plate"? And what should I do if someone put rtv silicone sealant on that plate, assuming it's a metallic gasket, hence bending it upon upper manifold (if I said the correct name) removal ? This question is out of foresight as I ran into this problem before while changing the spark plugs on a Kia sorento years ago.
You got part numbers for the gaskets your talking about?
Sorry no
Very informative, good step-by-step explanations. I’m pretty sure this is the cause of my leak. Everything seems to be accessible. Can’t complain, my Sienna has almost 20 years on it, 165,400 miles. Kind of an odd place to start leaking, though. 😮
I saved this video 2 years ago thinking it could benefit my wife's 2004 Toyota Sienna LE 8 seater. It was leaking coolant and was overheating unnoticed by her and own son, until it got towed for unknown coolant loss 2 days ago. The following day I refilled it with coolant and decided to test drive it. I saw the spike of the temp gauge on my way back to our place but noticed no coolant spills on the pavement, so I pulled over and decided to tow it back to prevent further damage. Yesterday afternoon I decided to find the source of the leak and found that the T connectors of the heater cores of the front and rear broke. I replaced it with a 5/8 inch heater hose T-connectors and refilled with distilled water this morning. Fired the engine and it looked fine, no overheating and decided to drive the vehicle to my friend's house for a recheck. When my friend, who's a driver mechanic, came back he said there were pools of wet leaks still in the front and passenger side and possibly a massive leak. That was what made me watch this again. Over the years I have replaced parts and maintained this vehicle religiously, since this was what the family uses for any occasion, e.g. school, work, errands, road trip coast to coast, etc and no matter what haters write I still consider a reliable vehicle.Guess I have to check the water outlet now for the first time in 16 years. This video will be helpful. Thanks for sharing. You make it appear so easy. Well done.
Thank you and glad that you save it.
You are a VERY VERY GOOD MECHANIC 👨🔧
Thank you
cool detailed video thank you, my 2004 Sienna AWD has the same coolant slow drip that I've been tracking down to the same area, very helpful video, (I changed the spark plugs and coils like a year ago, I wish I did this gasket change them)
Great video! thank you so much for posting it helps a lot of people including me.
Thanks for the video ! have to change my knock sensors you helped me out.
Just discovered this exact same issue. Same drip-same place. Saw the leaking area while I was doing valve cover gaskets/spark plugs. 154,000 mi on a 2005 Sienna. I am in state of denial since I have seen plenty of this engine already. The good news is I have learned the "tricks" to removal and installation of the Plennum which you demonstrated. It's a slow leak granted, but te repair has to be done. The back valve cover gasket oil leak HAD to be done ASAP since it was leaking oil on friends driveways and such. Great video! Terrible music. :) I'm subscribing though.
uaart1 thank you
Thanks for this very valuable information.
thanks, we have the same problem
Thank you. Exceptional video.
You welcome
Thank you for the Video, this will save me a lot of time!!
TT Innovations you welcome
Great video. Thanks for sharing.
Very informative video thanks for posting!!
Thank you
Quick question. When you remove all the top parts to get to the thermostat housing. Did you have to pull the injectors out or can you get away by just unclipping the wiring harness so that you don’t have to pull the actual injectors out?
Thanks man. Very helpful 👌
Oh, the shop wanted $1300 to fix this , fyi , so its worth doing it at home
Take your weekend to do it to save that 1300$ for your vacation 😆 🤣 😂
Gracias,Dios te bendiga muy didactico, saludos
thanks for this video, will be doing this job, question. are you sure there is no gasket for this housing cover. im not confident on using silicone.
There is no gasket for this part, which Toyota also confirmed. This job was done correctly using the high heat and oil resistant silicone sealant.
Please do more mzfe engine. I just bought 06 Sienna I could use your help.
OK buddy don't forget to subscribe 👍
Great video, very very helpful, thanks for taking the time to show us the process, God bless in Jesus name
Thank you my friend subscribe so I can count on you as 1 ok thanks
Really appreciate your video. You saved me a lot of time and 💰. 👍
Won’t the silicone gasket maker specifically made for the water pump better then the black one you use?
I'm not sure
My man said the hell with torque values and just used the impact to reinstall the coolant cover plate and the manifold...lol. I mean I'll use the impact for alot of stuff too but for a critical engine part that has a specific torque value and tightening sequence use the freakin torque wrench bro.
Me too thanks
Great video. Thanks for sharing! One question: what size wrench did you use at the 5:28 mark?
Kaleb Bennett that is 12mm socket
Great video except one important, very critical part of the whole job; showing the part when you took out that challenging nut from the back of the upper intake manifold. You spent unnecessary time in the easy part and left the most challenging job out of the whole video.
Yeah that was hard. Do it from the right side not the left
Sounds Great!!
Gracias de mucha ayuda
Great video. I found that its much easier to work on the back of this engine if you drop the engine frame down. as much as the big bolts allow it.
That's great Idea 💡 👍
Lol.
Loved the hmong song.
Thanks for video 👍🏽👍🏽👍🏽
You welcome
So glad to find this video. I have the exact same issue and the Toyota dealer diagnose the leak as the thermostat problem so they replaced it with a new one twice due to the leaking continued and two weeks ago they put silicon over the thermostat and told me if it leaks again they will need send the van to a motor shop to take it apart as it may be some kind of warping on the engine and it will coast me $5,000~$6,000!!! How long did it take you to do the job?
Don't go to that dealership they don't know how to fix or diagnose nothing. The only thing they know is take your money.
Great video... I'd love to bring my car to you. Where are you located?
How long did this job take to complete? Do you have to wait for the gasket maker to heal for any amount of time before you put it back together?
Ivan Perez 4 hours
Leaking coolant valley pays big money for techs
I'm a total amateur. Took me about 16 hours, being very thorough, I don't own a power ratchet. Also replaced intake gaskets, and rear spark plugs.
I've been driving my van for years with this leak, and not its getting smelly, but doesn't loose more than 1/4 cup every 2 months, probably time to fix it
Fix it before engine overheating
Should i replace the intake manifold gasket set?
If still good you can reuse it if you got the money replace it will be better.
@@alltsab thank you. the repair would be almost free if it weren't for the $100 dollar fel pro intake gasket kit
@@deriklfixit bro you buy fel-pro is junk. You should buy beck/arnley brand or mahle brand they are not that expensive but OEM quality. Next time if you want a good gasket this two brand is the best for the money. O'reilly's carry both brand. Autozone carry only mahle brand.
What size is the rubber hose that you replaced?
Not sure what Size but at the dealer they have it
@@alltsab Thank you for the great content! Love your videos
@elibalsam522 thanks for watching very appreciated
Hello Mr. Tsab, I just noticed the exact same leak under my 2004 sienna, some coolant between the engine and transmission. I only see one drop on the concrete every month so I think the leak is minor for now. If I leave it would it bring further consequences. Thank you!!
Jorge Guerrero any coolant leak can cost head gasket bad. If you see leak check your coolant often. This type aluminum head and block it doesn't show temperature go up. I do recommend get it repair if you see drip.
I had the same problem on 2004 sienna with 80,000 miles, on my sienna it was the plastic thermostat housing body leaking (replace the plastic housing body and thermostat and round thermostat gasket with Toyota OEM part) what was also leaking was a small hose off the same area that was 6 months ago and it fixed the problem; now it has a small leak again very very slow and now I'm thinking its this gasket on Tsab video =( , I also replace my radiator with a quality aftermarket on I got from Amazon (so far so good)
TT Innovations make sure check for your fan. My reservoir is over flow. My temperature gauge doesn't show high but my reservoir is over because my fan control module doesn't work. Also that cause over pressure sure it have this problem for my van.
Hi Mr Tsab I have Sienna 06 coolant leak on left side, under engine.I thought oil pan gasket,replace new gasket still leaking. After investgate the coolant leak come from engine above engine oil pan. How to fix it, thanks
Jorge Guerrero yes water is very important to the enginge. It can cause your car go over heat and it can blow your head gasket. In your temperature gauge may not show go high but it will over it. I believe your case it's water pump leak. Replace it sooner is better when you do replace your water pump replace the timing belt and other parts that necessary also. Thanks for watching please help subscribe.
Great video ! I’m planning to do the same my question how much time would it take the replace the all thing you did it please.
Minimum 3 hours with power tools
@@alltsab , after doing I will post it thanks again.
@@Maxson631 great
Can you tell me what tools you used to clean the gasket mating surfaces ? Thank you for the video
You can use Razor blade to clean it. I used wires brush and air sand.
Lookup 3M roloc discs. The white roloc bristle on a right angle die grinder is perfect for cleaning gasket off aluminum parts without scoring or damaging the part.
@@bavarianblessed thanks bro
Just replaced the water inlet tube, it broke and the wife drove it and started smoking. Got it all put back together now add, coolant, and its leaking out as fast as I put it in. Any ideas?
You need to tracking down to see where it leak from if coolant leak that much shouldn't be hard to spot where it leaking bro.
Thank you for the video! I'm working on my 05 Sienna right now. Would you happen to have the torque specs for the water outlet assembly? Thank you...
Sorry I don't...
11ft-lbf
Torque specs?
Do u get a coolant smell when car warms up mine did and resivor dryed up and the coolant was on the floor before this acord i changed my nock sensors and harnes after putting all partd back on this happened took to the shop to see if they can fix i hope this is the prblem thank u
Yes happen to a lot of the 3.3l Toyota engine
I took it to the shop and they said it was head gasket but it is not so im going to do the job myself i notice that after the enjien warms up that the coolant also runs down the back end of the car near the gas tank it is a 2000 avalon
What tools do I exactly need to perform the job was thinking about starting tomorrow can you help , great video by the way 👌
No special too need it as you see it in my RUclips
I just did the whole process but it seems to still be leaking from the same spot under the transmission any suggestions?
My car same problem leaking but I need the seal I know you used the silicone but I need help for seal gasket…you know where buy ? Thank you
You can buy from toyota
@@alltsab so you know what they call for the name seal gasket thank you for answer for help
I'm not sure what type of seal gasket you talk about. There is no seal gasket. I only used silicone
Im hoping my camry has this problem and not a HG leak... The coolant collects on the transmission just like this one
If 3 3l then very much it
@@alltsabthanks! I will find out soon. Your video is very well done. Just curious How much would you charge for a job like this?
@dannyduds1058 depends who do it. Dealer can cost in the thousand
White big smoke of coolant where could be the problem, the car was overheating recently bad radiator.
Could be blown head gasket
How much can it leek my Avalon has a small leek how long can i drive checking the fluid levels every day
Zachary Leonard any coolant Leek is not good for your engine. you should fix it right away.
All Tsab how much would a shop charge for this
Great video, man. I got a coolant leak near the upper water bypass hose on my 1MZ-FE. Could it be the intake manifold gasket instead of the inner water outlet?
Highly doubtful it's most likely to be the same issue as in the video. It was the case for mine as well. Pain in the ass to do but while I was in there did valve cover gaskets plugs and knock sensors.
@@nb6584 , thanks for replying. You're right. Luckily the leak has been minimal so far--I check the tank level frequently. I've also used an infrared thermometer to check the temps in different areas of the engine--so far, so good. But when I do get the inlet valley fixed, I'm taking it to a pro who's done it a couple times. It's way out of my league. Thanks again.
Same problem that was with me
Wow common problem with sienna and other Toyota
@@alltsab Yes sir, but it is an old model 2004
omg, I am in California. Can I simply fill the radiator with water to avoid a fix? LOL
That way doesn't fix it but create more issues that all.
I have a parts car 05 sienna fwd 3.3, leave a comment for more info. Im in Michigan
Looks like it is a common fucking problems with these junks.
WRONG SEALER….thanks a lot now 2.5 years later I’m dissembling again.
What sealer did you used my still perfectly fine
What sealer did you use? Just curiours, because i used ultra black gasket maker, and i thought i should have used ultra grey gasket maker???
@alltsab Your video is still helping people years later.. thank you.. I have a couple question though.. What brand sealer did you use? Permatex? And how's it holding now? Thank you in advance
I have an 06. N its leKing exactly like this! Omg i feel like i cant do all that work. But its just fucking bolts i will have to recording myself or something bcuz i think i qill forget. I have a bachelors but i have no confidence on remembering where all those parts go shit! I know i have the same issue n just need to get all those tools. How long did it take u!?
5 hours
took me 7 hours, just finished this yesterday. if you don't works on cars, this is gonna be hard.
