- In this video I show you how I removed the intake manifold on a 2004 Toyota Rav4 2.4 4cyl so we could get a better look at a coolant leak. As always please refer to your shop manual for the proper instructions and repair procedure.
I'm watching them out of order but still enjoying the way you explain everything without being condescending and it feels like you are talking to the person watching. I know these are older videos but I'm thoroughly enjoying them. Thank you Mr O.
Sir, you do a really good job of giving detail instructions on disassembly for the task at hand. I especially like your patience and seeking info when coming to a problem. I do a little wrenching myself and I like working with guys like you.
Really a wonderful video, thanks! I thought I'd mention the Intake Manifolds on 2004 RAV4's (and maybe other years) are known to go bad internally with the result being a louder than usual engine at various RPM's. No squealing or anything like that, no check engine lights, no loss of performance. Over time, the engine starts sounding more like an old lawn mower than an automobile engine. It happens so gradually that you don't notice until it gets particularly bad at lower RPM's. A good way to diagnose is with a mechanic's stethoscope from the bottom. Another characteristic is the louder "rattle" will peak at about 1600 or 1700 RPM's then fade away again, but even that doesn't happen every start.
As for that awful bolt nearest the battery, that will take the longest to remove and reinstall. I had to disconnect the hot lead from the battery and move the cabling back to have enough clearance for a socket wrench. This is something to be careful about because you don't want to short the positive lead to ground, otherwise you'll be making a special trip to the Toyota dealer for a new fuse block. To prevent this, disconnect both battery terminals temporarily. When reinstalling the intake bolt, I recommend duct taping it into position (small piece of tape) so when you go to tighten, all you have to do is push straight back with the socket. I failed to do this the first time and lost the bolt down in the engine compartment. That ended up being 30 minutes wasted trying to locate the bolt.
Oh, by the way, I purchased an aftermarket Dorman intake manifold from Amazon for about $165 as I recall. No problems and the car is nice and quiet like new.
Your biggest asset is your patience. Truly amazing!
His biggest asset is his ladies patients 😘
Had the same problem with a customer's 05 RAV a couple of years ago. The car had about 70,000 miles. For them it was time to buy a new car(a Subaru Outback). They offered me the RAV for what the dealer was giving them. The dealer didn't know about the leak. I declined and now after watching you I know I made the right decision!
Lol smart man :)
My Biggest Respect for all Mechanics outthere , because they have to remember where everything and every single bolt goes back where is supposed to go, and doing it right. 👏
Any video that rips apart an engine (or intake in this case) is great! Combine that with it being a SMA video.. then well, you have hit the top of the mountain boys and girls.
1999 toyota ranv coolant leak rear of engine hope it ain't head gasket. Already working on 1995 honda odyssey with timing belt failure. Doing all . Valves, gasket kit and timing belt kit.head at shop. You and others taught me well. Greatly appreciated especially now that I'm retired on fixed income
This has changed my mind on ever owning a Toyota
I've seen a lot of your videos but this is the first Toyota I've seen with problems. My wife's 2009 Corolla has never gone under the knife. Interior looks like new.
If you ever do anymore. Pull the intake, exhaust with the head. As an assembly. It so much easier other then getting the knock sensor and harness bolts back in there from the rear.
Here's a quick trick to help get the intake out without removing the fuel rail. Disconnect the motor mount bolt and use a strap from back of motor to front of frame and roll the engine forward an inch or so. Then pull out the intake.
The look of disappointment as you describe a diaper is gold.
I was considering buying a 2005 Rav 4. Now I can make a more informed decision. You are very patient.
always wanted a rav 4. this video cured that want
Have to do the intake manifold and this actually helps a lot
I work on the service side of toyota. And those 2AZ-FE motors are notorious for oil consumption. I would recommend a rebuild if your gonna do that with the timing chain cover reseal. And yes the water pump sucks in those. After 60k you'll start to see coolant residue under the shaft... And after 90k oil leak on the timing chain cover, where the head meets the block. And about 120k is when the oil consumption starts. Sometimes 60k.... Good luck on the vehicle.
Veritas Aequitas Good to know. Thanks for sharing.
Veritas Aequitas i got my pistons and rings replaced for recall on matrix 2009 . Now car vibrates in drive or reverse at stop light. Any idea?
My scion tc 2005 has over 200k with the stock water pump still running strong and timing belt cover not leaking
*timing chain
Alex Vega I hope you're saving up for a rebuild. I would.
Im a certified youtube journeyman now. Tnx Eric O
Pressure test and patience would have revealed that leak. The coolant has to go somewhere and even with other small external leaks the "diaper" would eventually reach saturation and become obvious. Under pressure in a cold engine a good thermal imager would catch it also. Not many places coolant could have been escaping in that scenario. Cooling system leak dye also. Just some thoughts... love your vids btw 😎
The wife just bought a new Rav4 with 1.8L . She got the 7yr. 100k mile warranty. Probably trade it in before the warranty expires.
Wow! I have never done any of these,but they seem a pain for a 4 cylinder.
You really got me hooked on your channel Dr O. My wife was like : " What the heck are you doing on YT all evening ? " I'm like : " I'm watching Dr O! " She's like : " I never knew Dr OZ is on YT! " LOOOL! Then she's like : " Well,at least you're home watching YT and not out cheating on me! " LOOOL! What can I say...
Haha don't let your wife see me and fall in love haha no jk man. Well I am glad I can bring you some form of entertainment :) and stop you from having an affair lol
The foam looks like it serves as a support for the intake aswell, it is plastic so I think it can flex a lot more than other materials and possibly crack easily without support
+1 on the stripped threads for the head bolts and timesert repair of the block. My Scion w same motor did same thing, tremendous PITA
Yep been checking out timesert all ready... hope not but we will see...
I'll sell you the kit, half price!
hmmmm may be interested. We will see what happens in the next couple days :)
You ain't kidding they're tight! I just did an intake gasket on a corolla and like you, I, started with a 1/4" drive...Managed to break them loose but WOW they were tight!
Sure were tight. Thought for sure I'd be bleeding lol.
Is this the first, Welcome back to the south main auto channel intro? Lol
ill put this on my to-never do list
Nizzy10 right?!
Is the rest of the car rust free? Is interior in good shape? Bite the bullet, get a used Japanese 2.4 engine from J&J. Install. Done!
Did one that was locked up .. replaced the motor with a recycled motor took three days because had to disassemble the lower half to turn crank which was a pisser. . To get the flywheel to turn .. some cussing happened. .lol good job Eric even if I'm 4 yrs late .
I know this video is old but i was reading the comments amd by god why do some people try and sit there and be a keyboard warrior and go back amd forth with Mr. O when he clearly knows what he is doing . whew
I'll be interested to see what I see when I tear into it. Evidently these have a problem stripping out the 3 rear head bolt holes in the block. Sounds like a party to me!
Sounds good Eric and I'll bring the beer! That intake manifold was a monstrosity. They could have made an oil pan out of that thing as big as it was. Nice work!!!
Lol... well if head bolts strip out we'll need some beer haha.
If those head bolts strip or break, we'll probably have to switch to hard liquor LOL....Have a good night Eric...
Lol haha Nite Terry
I guess this giant foam piece is to insulate block heat from the intake, providing cooler air to the engine. And we all know: cooler air=more O2=more power
And here I thought I had it rough with the intake manifold on my 1996 toyota tacoma which has the engine essentially rotated 90 degrees. Much easier to access. After I watched the whole video I saw it's not exactly the same. My manifold has an upper, and lower section
May not have applied here but I often find raising the engine slightly helps with removing the intake or whatever when I get in that situation where clearance is a problem
Oh yeah for sure but this being AWD it's locked in there pretty good...
"Sweet victory baby"!!! Absolutely
The insulator insulates! It keeps the cheapo plastic intake from melting and buffers the viberation so the cheapo plastic intake won't crack and break off.
I remember seeing a trick where in this case where you just need that HAIR of clearance on FWD cars, you can rock the car front and back in park to rock the engine and trans front and back as the parking pawl hits the stop and tries to rotate the drivetrain as it's dragged or pushed by the rolling car. Put your hand or foot on the parking brake, rock the car back and forth really violently, and then when the engine had jerked and leaned far away from the area you need clearance in, slam that parking brake on to hold the chassis in place and therefore hold the drivetrain in place torqued away from your parts. 👍 It'll give ya that 1/2" you need, works even better on total piles that have torn every motor mount asunder and there's nothing but hope and dreams keeping the lump connected to the chassis. 😸😸😸
It's a heat insulator supposed to go to store some of the heat off the block
super vid my brother. keep up the good work. real appreciation here :)
That Rav4 rack and pinion looks like a real PITA to get to when it needs replaced !!
Don't you love the manufactures you have to drop engine cradle to do rack and pinion
difficult car to work on, but you did it, well done...
Found these, gonna run thru the set!! Nice ob finding the leak!!
It's hard to assume if head gasket is leaking especially on tight space could be small crack on the engine block i encountered once
Great video
This is why I don't mind paying my mechanic .
it's a lot of difficult talented work . To work on any car . I'm an electrician for 40 yrs
My favorite and super easy Toyota engines were 18 20, and the 22re
I keep expecting him to lay the old uggs Duggan on the. Bat and watch sparks fly....mr universe said "YOU ALWAYS BRING ME THE BEST VIOLENCE"
I have to say i enjoy your vids. This one made my chuckle.
I got frustrated just watching you trying to get that manifold out.
Lol wait till you watch me do the head bolts on it too...Part 2 I get real frustrated :/
South Main Auto Repair
Oh dear...
I find working on cars keeps my curse word vocabulary up to date!
Hey back in the day I use to make them up if I ran out haha
I seen that before removing the fuel rail and injectors you actually pulled the intake back far enough to see the gasket, so I'm wondering if I can get away with not removing the fuel rail and pulling it back far enough to replace the gasket?
I think you can do that
No, Doctor O, the wire mesh is to keep the squirrels and mice inside. The rodents are what makes the vehicle go. And I hope these head gasket jobs pay at least eight hours. I needed to remove the intake manifold on my 2009 CR-V and I discovered it had to come apart in two pieces to clear the radiator. Well, there are five bolts holding the inner plastic/nylon piece to the back of the metal intake. Once I figured that out by blindly feeling around in the back it came out easily. Assembly was a piece of cake even though I had to put it back together blindly. Once you know how it comes apart, putting it back together goes pretty darn quick.
would you consider doing a video demonstrating how to bench bleed a 4 port master cylinder and how to install it?
"Giving her the beans, giving her the beans,
We will come rejoicing, giving her the beans..."
🤣🤣🤣🤣🤣
Its amazing how people dont take care of their cars and let cra just sit in the engine bay, the channels for water run off, and then wonder why things happen. id be interested in seeing what the inside of this poor rav4 looks like. GROSS by my standards. hahahaha. my 2013 s60 is pristine and when it goes to dealer for anything, they cant believe how new it looks and still smells. Excellent video Mr Mechanic!! details and very nice disassembly process. you should have been a surgeon. you need work gloves by the way?? 😊
Nice video. Definitely helped me some
Wow, huge job but very cool! I have 01 rav 2 rad changes (rad gasket) but I see tiny lowering of overflow bottle ...engine starts but a little long crank time also on start races to 2k idle but slows right down ...maybe gasket gremlins? Thanx for max video!
Is there any issue with removing the foam "diaper" and not using it anymore? I had always thought it was bad to have that there as it seems it may be the cause of the bolts stripping. The foam insulates the aluminum block thus keeping the heat retained in it. Since the opposing side doesn't even have one, the heat dispersion is uneven. This perhaps causes the aluminum to fatigue thus making the bolts strip. I have a 2009 camry with this motor, and from what I've read, they "fixed" this problem by making the headbolts 10mm longer. Not really a fix in my opinion....
I had the exact same issue at 384,000 km. I tried various head gasket/stop leak products . Nooo success. The gasket must be replaced & found a mild warping in the head. Ended up scraping the car
In my Haynes manual in the first paragraph it says to remove the fuel rake.
Nice job dude...man, those snap on flex head ratchets are the cat's meow, got like 20 of them. I didn't like the comfort grips at first but they have certainly grown on me. I have a hammer head 3/8dr on the way, we will see how it goes.
They are the bees knees that's for sure. I got myself a pile of snappy ratchets my self. Felt the same way about the comfort grips too, but they do seem to work ok. The earlier ones with the fat handles use to snap in half but now they switched to these skinny ones and they hold up good. Congrats on the hammer head, you'll love it!
Fantastic- ⭐️⭐️⭐️⭐️⭐️
Thanks Steve!
the "wire mesh" is probably a flow straightner...
Always remember to run after pulling pin and throwing the grenade.
+Jeffrey dontyouwish Yes you must take cover.
@@SouthMainAuto ends badly if you don't lol
You will need that insulator diaper thing. Well not right away but it keeps the heat off that plastic intake. After a while if it doesn't get put back on the intake will get heat soaked, bc brittle & crack. But it wouldn't happen for a while depending how often you drive it. Might last for ever or might end up cracking the intake in a few months.
Hopefully the newer "2018" Rav4 is a little cleaner to take apart. While I'm hoping maybe I'll never have a problem with the intake or the head gasket.
Thank you for the info,,,n great job!
I just subscribed to your chanel 👍
Looking forward to more good content.
I am going to half to do this to a 2002 Camry 2.4 liter, can you give me the part number for the TAP Set and did it come with enough inserts or did you purchase separate, then that metal guide plate, did it come with the tap-set or did you make it? Most Appreciative!!!
Camry 2.2L has a thing behind the ac pump that too that don't need to go back on. 😎
I think the sponge is just insurance to help support the intake, maybe from vibrating and cracking
2:00 - I could have really done with those hose pliers last weekend.
Do you have a video on diagnosing a coolant leak on a v6 rav4. Mine is a 2007 and I noticed the smell today coming from the engine bay. The resevoir was empty and I could see an area of moisture as well as more liquid than normal coming from unusual areas on the skid plate.
Taking it apart wouldn’t take long,getting it all back together right might take me a couple weeks
Great Video, thanks for sharing!
The corollas eat intake manifold gaskets but the repair is quite easy. Wouldn't be pretty if these had the same problem.
Oh yeah true story. The 1.8 in the cars is much easier!
How many miles were on this car? My sister had an '02 that had some major antifreeze leaks.
This happened on my old 04 camry too.
.... just wondering Eric if once that manifold was off, plug all the disconnected coolant lines and openings then pressurize the cooling system to 5 or 8 lbs with your handpump thingy in the rad fill hole .... make a leak or seep easier to see ?
I am trying to make some room to remove the timing chain tensioner without removing the intake manifold but the wiring harness is on the way. On 21:00, that plastic part attached to a metal bracket on the right side that's holding the wiring harness, is that on their with a fastener or does is just slide on and off of that bracket? Trying to determine if I can simply pry it off of the bracket or not. Thanks!
Handy Daddy It should slide off the bracket if I remember right
Eric O I'm struggling to watch your videos. I'm a big fan of yours and love watching them. The problem is, I watch them on my TV. The advert starts part way through, then when the video commences, it automatically jumps to the next video. I've contacted RUclips many times with no reply. I was wondering if you had the same complain from other subscriber's?
Do you have to take out the intake to get to the head gasket?
I'm late but that diaper is a sound damper.

Adds rigidity to the “plastic” intake manifold by absorbing vibration from the engine. And it also is a sound damper
@@wagonkit bit late with a comment but it also keeps heat from the plastic intake, that it causes the head to fatigue speaks to a design flaw in the block
@@charleswp71 I actually was thinking that. I think they fixed this issue by simply making the headbolts longer. Not exactly a fix, but I think (hope) they did it with the 2007 and later 2AZ's. I have a 2009...lol.
I see that you got the intake manifold out without having to remove the cowl and what the cowl bolts to.
Might save me a little work, thnx.
Would this be the same for the 2007 Rav?
You asked for it you got it, Toyota!!!!!!!!!!!!!!!!!!!!
rav4 are my faverat
Thanks for the video!! Looks like February is head gasket's month. lol
How many miles that car has?
I'll look when I get back to work... 150's I think? Head gasket special in Feb for sure.
I'm late too, that screen in the intake is most likely a heater.
Thanks for the video.
Dang man. You must be putting in crazy hours to have time to run a shop, record, and video edit. Great vids though!
Dedication haha
Stripped head bolts time sert make a kit for that
When i was watching you take that intake off in my head i was like remove the torque mount and push that car back a little in park will make the motor move forword
I have the 2004 Rav4 shop manual, and it is terrible; very user-unfriendly. My Rav4 did great until 140k miles. Now it's falling apart left and right.
My toyota hilux was worked on to replace the coolant bypass hose. The intake manifold was removed and since then the truck performance reduced. What might be the problem here? Is it a must to replace the manifold gasket after opening it? How do I tell if there's a leak?
Hey eric I have been watching ur shows here on RUclips and I like it good job I wold like to make a suggestion if I may it's called a butterfly air gun
ryan wirling Yep actually I own one. It is about 15 years old. Still works great :)
who said Toyota's never need major repair ????
@Captain Caveman He said the time is 4:24 not the mileage!
Who’s to say the owner didn’t overheat it?
The 2AZ-FE engine, was Toyota's Windows Vista. A motor built in Kentucky, but having the similar planned obsolescence of Detroit built Sedans. Non mechanics should stay away from 02-06 , 2az-fe !?! Peace.
2azfe is 'junk' compared to Toyota's prior 5sfe 4 cylinder.
ferndog1461 my 02 Camry with 200k miles 2azfe no major repairs
good vid
Holly crap! You're only starting to grey in this vid lol
Hello...i would like to know if the head gasket toyota engine rav4 1AZ FE will fit the 1 AZFSE?
Oh what fun, I cringe watching you do it. I'm glad I don't dig that deep any more or try not to. People and especially customers do not realize the amount of work that it takes. Boy that one sure is tight. My hat is off to you.
Totally agree with you..Many times I've heard customers say "I was told by the person I bought the car from that the car only needs a 20 gasket ." Then you give them an estimate for a HEADGASKET and they almost have a heart attack!
Thanks George Heri. Some times you gotta bust out the shovel and start digging. Heck this part was only to see where the leak was lol.
Mobile AutoMD well some times it is only a $20 gasket.... ohhhh and 12 hours labor haha
Exactly!
I’ve seen every major car trashed, bar none, depends on the owner taking proper care and maintenance, and not dogging it.
Why not use dye & uv light?
Hey Eric, do you ever pressurize coolant systems to pinpoint leaks? I like to stick a bike pump on the small hose fitting coming off the rad cap to the overflow tank and pump up the system. Generally the leak will be show itself even on a cold engine. The only time this trick didn't work was on a Subaru head gasket that only spit coolant out when really hot and under load!
Yeah I actually pressurized this first and when I couldn't see behind the intake that's when it was time to pull it. Could see the "t" fitting leaking and the water pump but that was it. I agree, they usually leak best cold.
That would have been cool to show in the video! Maybe pressurize it again with the intake off to catch the leak on camera too...
Yeah if I get a chance I will
The giant diaper is a heat shield to keep the plastic intake from melting
If this was my dad doing this he would have dropped a thousand F bombs, S bombs, MFer bombs and crap bombs! He was your average Navy mechanic!
what is the green knob next to the intake for??
I think you are a Raw4 expert.
My raw4 has a very low mileage. Very high fuel consumption . How to fix it. PLEASE help me.
