What exact year is this gx470. The 4.7l v8 from toyota/lexus has gone through slight, generational changes in the construction in the motor and transmission. I went through this w/ my 06 tundra
What is the make and part number of the wrench you use at the 6:57 mark; the little offset of the ratchet looks like it would be real useful!
Most of the links no longer work.
Where can you find that sensor that you put by the timing belt I caint find one like that?
just bought a GX470. 3yrs later and this video is still helping people out. Thanks a ton!
Glad the video is helpful. Thank you for watching!
Thank you for this! I just followed this exactly and the job went great. Only think that might be important for someone to know is the VVTI versions of this motor you want to rotate passed TDC so the cams don’t roll back. Mine is an 06 and that was what I did. Lined up at TDC and then rolled passed to the “T” mark. Cams stayed right where I needed and everything went smoothly. Thank you so much for taking the time to do this!
Mine rolled back. Scared the crap out of me. No damage or anything. I just placed it back to the right position.
Thanks for this video! I wouldn't have been able to ever do my own timing belt without your help. While I was in there I also replaced the power steering pump, alternator, belt, idler pully, new radiator, and all the other stuff. Still ended up being way cheaper than just having a dealership change only my timing belt
Glad the video was helpful. I’m sure you saved a ton of money. Thank you for watching!
How much they quote you ??
Me three!😅😂😅
That was a heck of a job to make a video on. I can appreciate the work that you put into this video.
Thank you for the excellent thorough detailed video and for providing CONFIRMATION that I do not want take on this project! 😂
I don't even own a Lexus gx and I watched this. 💪
Jorge Meza thank you for watching. If you ever get a chance to work on Lexus you know what to do😎
Jorge Meza me too 😂😂😂😂
Yesterday, I went through this video as I replaced my timing belt and water pump. Great video and very helpful! I am the third owner of a 2009 GX470 which now has 192,000 miles on it. I bought it with 143,000 miles and there was a timing belt sticker stating a Gates timing belt was replaced at 140k. Not so sure the second owner actually changed the timing belt or maybe they did and the Arizona heat over the last 50,000 miles really aged it. The Evergreen belt (not Gates) has cracks all over it on the outside. When passenger side cam was lined up, the driver's side was about half a tooth off the mark and the crank was about the same. Since a belt can't jump half a tooth, I assume the difference was due to the belt stretching as it aged and cracked.
As I went through the process, I had a few differences and want to let everyone know:
1. My crank pulley would not come off by just wiggling it or tapping it or using a pry bar. I had to rent a pulley removal tool from Autozone. Luckily they were open on the 4th of July! You have to use the crank bolt and turn it in maybe 5 or 6 full turns so that it is stable. Then you use the pulley removal tool seat it in the depression of the crank bolt head. This particular kit (the orange box kit) has a central bolt that when seated on top of the crank bolt, the head of the central bolt almost touches the radiator. I used two wrenches, one to hold the crank bolt still and the other to twist the central bolt in. Eventually I ran out of room using the crank bolt, so I fashioned a 1/4" thick piece of square steel that would sit inside the pulley and be supported by the crankshaft. That gave me more room to work the central bolt on the removal tool and I probably could have used that square steel piece from the beginning without messing with the crank bolt.
2. There are slight modifications to certain years. My a/c compressor did not have the lower L-bracket with the two bolts in it. I only had to remove one bolt from the top and one bolt from the bottom of the a/c compressor to free the fan clutch housing. No L-bracket to worry about.
3. Inevitably I usually end up dropping and losing a nut or some other small but critical part. This happened with a 14mm nut that goes to the stud on the right side of the fan clutch housing. Today I'm going to the Lexus or Toyota dealer to get a replacement nut, but from now on, I want to have some spares on hand. Maybe a couple 14mm and 12mm nuts for this particular job.
4. Lastly, check your new replacement parts with the old part getting replaced, if possible. Radiator hose shapes, for example. In my case, I ordered a thermostat seal that Amazon stated would fit my GX470. Nope! It's about half the size. I had to use the old one for now until I get a replacement. It was not OEM but was from a reputable manufacturer. Didn't realize it until I removed the old thermostat.
5. Oh, one more thing. I realized my coolant system needs a serious cleaning, not just a flush. I did soak a few parts in vinegar like the crank reluctor wheel that works with the crank position sensor and the part behind the thermostat that connects to the top of the water pump. A good coolant system cleaning and flush is now added to my To-Do list. This will be a winter task. Why? Yesterday it was around 110 degrees outside. I did all my work inside my air conditioned garage. But when I added coolant at the end, I rolled the vehicle out halfway. The heat outside was so high, the vehicle wouldn't engage the heater, or at least I couldn't tell if the heater was engaged. So I'm not sure the heater core could have been drained. Maybe this will all work better in the winter.
Great video, thank you for being so detailed! The torque numbers are extremely helpful! One thing that might help folks out there is once you line the crank and cams up, move them just a bit more to the T marks on the cams. This will stop them from walking once you pull the belt off. The tip on putting silicone lube on the O rings is crucial, excellent work my friend!
Very well done. All steps and no nonsense.. ✅. If you watch this 4-5 times it will give you confidence in this job.
Glad the video was helpful. Thank you for watching!
Well Done Brian! Feels better knowing what I'm paying the dealership for.
It’s a lot of work for sure.. thank you for watching!
Great informative video, Thank You!
Just confirmed that this job is a bit outside my current skill set.
Thank you X 100! I used this video to perform the repair myself. The only thing is i wished you mentioned the opportunity to replace camshaft and crankcase seals while in there. I wish I knew that as they are cheap and easy to replace. Also, Once I replaced the timing belt and everything else from the kit, on my way out I ended up also replacing the alternator, the drive belt idler pulley, the drive belt tensioner pully, the fan bracket, and the fan cluch, as well as the drive belt itself (used OEM part). I got OEM Japanese made replacement parts (Aisin, Denso, NSK) online cheap enough so I did not mind spending couple hundred more to avoid doing these separately in the future. My vehicle has 152k miles on it and it had the original belt and original pump. I am on a mission to see how many miles i can get out of this if I maintain it right with Japanese parts. These are all items that wear out and all the bearings were noisy on those items and possibly failing. I did not change the bearing on the AC compressor (yet), but that is easy to get to any time. I also replaced the radiator, which was leaking just like the water pump is always leaking like you showed in the video. I was quoted by Toyota dealer $1200 for the timing belt and water pump, $1300 for the radiator. And that did not include alternator ($600?) or any of the other parts i replaced in the process. I spent $600 or $700 on Japanese made parts and did it ALL myself, saving at least $3000, if not $4000! Yes, it took me many hours but I am a novice. Without this video, it would not have happened.
ahhh i wish theres a video on the crank and cam seals. Nothing showing the replacement with the engine in the car.
Top quality how to. Straight to the point and very effective. This will come in very helpful! You were able to show everything so clearly leaving nothing to the imagination. Awesome job on both the repair and documenting it!
thank you so much for this tutorial. I finally did mine and this is the absolute best video on this subject. I only had to buy that crank pulley too and managed to take off the fan and steering pump wheel without the mentioned tools.
dntninja Glad the videos helpful. Thank you for watching!
If you use the “T” marks on the cam covers instead of top dead center, the cams have a much less tendency to move. The “T” mark is for timing belt service anyway
Not so fast. It varies by year and model of these Toyo 4.7s. Some years say do it at TDC, some say to use the 'T' ATDC mark you are referring to, and others (mostly the VVTs like this one) have you rotate counterclockwise to 50° BTDC (there may be more, check your service manual or the directions in your AISIN kit to be sure) to get to the safest point where the cams won't be under pressure and spin on you when you remove the belt to eliminate the risk of damaging valves. I will say that this should only really ever be done when you are going to replace it with a new OEM timing belt with the crank and cam marks on it like the one used in this video.
Specifically for the Lexus GX470 (2003-2009) both the factory service manual and the directions that come with the AISIN timing belt/water pump kit say that after setting the belt to TDC prior to removing it you should turn the crankshaft counterclockwise to 50° BTDC:
Factory Service Manual:
"(2) Check that the timing marks of the camshaft timing pulleys and timing belt plates are aligned (at TDC).
If not turn the crankshaft 1 complete revolution (360°)
(3) Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approximately 50°
NOTICE: If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to come into contact with each other. So always set the crankshaft pulley at the correct angle."
Aisin kit:
"11. Using the crankshaft pulley bolt, turn the crankshaft counterclockwise by 50° until the notch on the sprocket guide is at approximately the 12 o'clock position. NOTE: The camshaft sprocket sprocket timing marks will move approximately 25° counterclockwise and will no longer be aligned."
According to the AISIN kit instructions, the above also applies to 4runner 4.7L V8 (2005-2009), LX470 4.7L V8 2007,
GS430 4.3L V8 2007, SC430 4.3L V8 2005-2010, GX470 4.7L V8 2005-2009, Sequoia 4.7L V8 2009, Land Cruiser 4.7L V8 2007, and Tundra 4.7L V8 2009.
Then you can remove the belt without the cams moving and put the new one back on making sure to align the marks on the belt with the marks on your cam and cam sprockets.
As long as you get the new belt on and verify it's in time by turning it over once or twice your golden. And yes theres a tendency for the cams to slip in certain positions
Thank you for a well done video and instructions, I am 67 and this is the first time I have ever done a timing belt. Debbie Hammer, Conifer, Colorado.
I’ve probably watched this video four or five times now. Preparing myself for the first time ever. :D. Thanks for this resource, Brian, I appreciate you narration.
Glad the video here for you. Thank you for watching and good luck with the timing belt.
How to Automotive having a difficult time with the black clip on the cam sensor wiring that needs to thread through the driver side timing cover. Extremely frustrating piece.
Garrett Orpin How did it go. We’re you able to complete the job
I needed this refresher. Haven’t done this in 10 years. I usually put a large piece of cardboard to cover the inside face of the radiator to decrease chances of damage. I’ve made that mistake before at a shop and had to replace the radiator. Great and easy video to follow. Keep up the great work.
the ultimate how to video.
very well done sir.
I will watch this 5 times for training purposes then I'm jumping on mine.
Thank you so much!
Glad you like the video. Good luck and thank you for watching!
Brian I don't even own a Lexus, but I sat through everything. Everything was clear and to the point thank you.
MrGert150 it a lot of work to do this belt. Glad you like the videos. Thank you for watching!
I watched so many videos related to doing this job and by far yours was the most detailed. I was able to complete the job and save myself major bucks in the process. Thank you!
I’m glad the video was able to help you get your car back on the road and help you save some money that’s awesome. Thank you for watching!
Hello, how much is this job? I'm looking into a gx470 and it needs it.... thanks!
I was scared of this job but this is a very detailed video I feel like I can do this. just need to get a few tools.
how's it going? have you made it?
@@zhonghaozhao919 no I don't have the truck anymore Inhave it to my kids mom to use.
Thank you sir, just did my 2006 lexus gx470 (timing belt/water pump) and your video was huge help thank you so much
Truly one of the best instructional videos I've ever seen and followed along with; thank you so much.
You have and will, save people tens of thousands of dollars
Completed the job on my 2006 Gx470. I placed the phone on top of the throttle body and followed your video. Worked about 1 hour or more every day, took my time and four days later it was done. I’m not a mechanic and mostly have basic tools I also replaced the camshaft seal on the passenger side, it had a leak. Thanks for the vid. Car runs good and strong. Cheers.
That’s awesome I’m glad video was helpful. Thank you for watching!
Great video Brian, I always take a picture of the serpentine belt (instead of drawing a picture) before i take it off to help with the routing when its time to put it back on.
Michael Salice I was going to print it out but my printer ran out of ink. But the picture is a good idea 👍🏻
this is an awesome video. i’m a total newbie planning to do a diy timing belt/coolant pump change with the aisin kit and this is giving me the motivation i need for such a risky/time-oriented job. thanks a lot!
THANK YOU for moving so efficiently and quickly! Some goobs would have turned this into a 9 part Mini Series.
Hi Brian. Awesome video. Just changed the timing belt etc on my 2005 Toyota Tundra. This video saved me a million times. Calling our the torques was extremely helpful. I can't thank you enough.
Lexus service department definitely earned my $1300 🔥
Haha.. I found that to be the case too. Especially since it's 94f in the garage.
Thanks for taking the time to explain this tricky job, and making it a lot easier. You have done an awesome job, not missing anything. This is so much easier to follow than reading the manual.
Awesome video! I appreciate the time you put in to making it while doing the job. As an auto tech for about 8+ years I was looking to get a basic overview of this job (since I've never worked on one of these specific Lexus's before). I like how everything you said and did was right to the point. My buddy has an 06 gx470 that I'm gonna be putting a Timing belt and water pump on and thanks to your video, I'm way more confident about doing it.
Seriously,, The best how to video I've seen
Dang I better just go to work and save my money so I can pay Brian do this type of work for me. Nice work Brian!
Nathaniel D.LOL It is a lot of work. Thank for watching!
Nice video. Well done Brian. I will pay every penny for a work like you did.
This is one of the best videos I have seen in a very long time. Great work!
This video is a top ten video in my book. Very detailed
Thank you! Glad you like the video.
Thank you so much for this video. Total lifesaver! Best step by step video on this subject on CZcams by far!
Excellent video! I’m not looking forward to doing this on mine but it seems more manageable than the 1999 Toyota Camry one.
Awesome video i just picked up a 09 with 114k and need to do this ASAP. Such a great help and detailed video. I see that you filled the coolant system and let it bleed itself. Has anyone ever sucked vacuum out of the system and bleed it that way ?
Wonderful video, thank you for posting this! Lots of steps, but looks pretty straight forward. I really like that Toyota has a simple tightening operation for the Crank bolt, unlike Honda with the funky additional angle after torque spec.
Wow, this is how a CZcams video should be made! Straight to the facts. Full of non-stop rapid fire information. If I need more time, I can pause it or rewatch it. At first, I was looking for a 10 minute video explaining the job, saw that you had an older one that was longer, so figured this was an edited one. Now I see that it really does take 40 minutes to explain the job. I guess I'll schedule an entire weekend to get it done. I think I'll buy the crankshaft pulley tool, but was wondering if people have experience skipping the tools for holding the fan clutch or power steering pulley? Can you squeeze an impact ratchet in there and do it? Or use screwdrivers or some other makeshift setup?
Well, Identifix tells me it's only about a 4 hour job. Maybe I'll get lucky and do it in a day. Identifix also tells me a rear differential swap on my IS250 is nearly 10 hours and people seem to do it in an hour. I guess it comes down to whether you do it the approved factory way or if you take some shortcuts. Maybe your timing belt swap is more thorough, with some parts getting swapped out instead of just quickly tearing into there, changing the belt, and bolting everything back together. Anyone who has done this have comments on how long it really takes?
Thank you for such a nice job on the timing belt replacement and the video itself.
Best explained timing video on CZcams. Thanks so much. Just subscribed
Awesome. Thanks Brian. BTW, you are blowing up. Just a few months ago you only had about 10K subs now you got over 35k. The word is getting out friend.
When you remove the T.belt,do the camshafts jump,because on the pilot,it jumped on me. All in all,great step by step procedures...
mckoy lach mine jumped! Did you have any issues afterward?
I set mine to the T and they didnt jump at all.
Thank you so much your video was fantastic very well edited and so much information. Wish I would’ve seen it before I started and had so many problems that I had to find it later to solve them. I subscribe to your channel as well and referred it to a mechanic friend of mine, who works on Lexus Toyota. Blessings for you my friend for helping all those in need Larry D.😊
Thank you.. I'm considering an 07 GX. This will be useful if I find one that hasn't been done.
Hands down best video ever, I really think was difficult to get all that on video all te information and instructions. It's Just awesome, thanks for it!
Great video, I need all that work done on my 2008 GX 470 lots of work
Gods plan sir thank you
Great video! I'm thinking about buying a GX 470 and wanted to know if there was a good video on replacing the timing belt. Yes, there is! Thanks!
The GX470 is a good one👍
So, I could not find a Lexus harmonic balancer wrench, so what I did was invert my serpentine belt and thread it onto the starter per the usual and then doubled up the belt, ran it counter clockwise and fed the length under the ribs and was able to create enough counter torque to pop the bolt. And just reverse the direction of the belt to torque back down to spec. Hope this helps someone cause I feel smart haha
great video , so helpful. got it done engine fired right up with out any issues.. after the truck sat for a week on cold start i heard a loud rattle shut it right off restarted and it went away. I reading it might be piston slap? It sounds like it was lifter tick?
Thanks for doing this. I think it's something I can tackle. Any ida what Lexus/Toyota charges for this service? Saving money is always good.
I noticed you didn't put it at 50 degrees. I read in the manual on a 2001 Lexus Ls 430 and it says to put it at 50 degrees forward then you remove the timing belt. My question is when putting on the new belt . How do you put it back on since the timing marks will be off at 50 degrees?
Great video! Appreciate all the details, very well done!
Be sure not to skip a skep. Lol. Great vid!
Thank you!
Excellent video - extremely efficient presentation.
Also, I just unbolt the power steering pump. Then you don’t need a special tool to take off the pulley
Nice and very very knowledgeable person👍👍👍👍👍👍
Awesome Tutorial Video!! Thanks for sharing your knowledge..
Nice work
I read and watched a bunch of tutorials for the GX and 2UZ-FE. A few people said the | | mark on the cam pulleys are for TDC and NOT for timing belt work. The "*T*" mark is for timing as well as a dot on the crank pulley that would be aligned at the very bottom of the crank pulley rather than the 2 o'clock position. The difference between the | | and *T* being that the T has no tension on the valve springs nor compressed air in the cylinders.
I read what I think was an FSM that described the T over the | | system. What do you think about that? I'm about to pull my belt off and wondering... I know it really doesn't matter as long as its aligned when done, but still.
any suggests on the getting the power steering pulley off without the spanner wrench? use a large screwdriver through the hole to keep it from moving?
Thank you this was extremely helpful
Cách thay bơm nươc và dây curoa cam rất chi tiết ,cảm ơn bạn đã chia sẻ hướng dẫn thay thế
Did the cams jump after tensioner removal? Thanks! Great video!
Great video
Thanks for the speedy reply. I was looking at a 2003 low milage verses a 2009 with high miles. I seem to remember that they have different engine designs? I cant find the info anymore??
I felt good watching this.
You are a Ninja!!!!
Excellent!!! This video helped me decide to purchase a GX and sell my 09 Lincoln MKS. I need a SUV that I can repair myself. Timing chain replacement for the Lincoln....😥😥👎👎👎
God send!
Outstanding tutorial. Thanks
Thank you for watching!
Not too bad a job. Nicely done sir!
YOU ARE THE MAN!!! Brilliant job! Planning on mine '08 GX470. Question? Get the parts from Dealer or get them online: AISIN/Mitsuboshi? Thanks a lot in advance!!!
Replacement link or replacement model number for the big tool with the red handle? Link is down and the tool seems to be generally unavailable.
Thanks for the excellent video!
Now I know why Toyota trucks run forever. Because they use those rubber bands that need periodic replacement instead of timing chains. They take so much work to do, you might as well replace everything on the front of the engine. It’s hard to be unreliable when everything is always new.
Don't understand why you need to unbolt the two AC compressor bolts next to the oil filter when it is only the bolt accessible from up top in the engine bay that screws into the fan bracket...?
very well executed video. as good as at gets
Thank you sir. Great video.
You're the man! Thanks for sharing!!!
Thank you for watching!
Thanks for the video it amazing it helps me a lot thanks
Does rotating the fan clutch counterclockwise cause any issues? Thanks
Outstanding - thank you Sir!
Thank you
Thank you for watching!
I like the way you explain your work thanks.
Carlo Grajalez thank you!
Thanks for this great video
Thank you for watching!
Very informative vidoe! Thank you for this!
Great presentation! 🚠
Hey How to Automotive. I have a p1340 code and I don’t know where to start! I have the manuals a multimeter and a new sensor coming in a couple days. The car starts fine cold but if it’s warm it will have trouble starting. Someone told me to make sure the wiring isn’t bad, but I’m just lost. Any help or existing videos that are similar would be appreciated. Thanks !
Such a good video. Thank you!
Thank you for watching!
Awesome video. Thanks for sharing
Question. The drivers side cam moved after removing the belt. It “snapped” under tension counterclockwise, about 20-25*, looking at the engine standing in front of the car. I just moved it back to its rightful place with the marks back in alignment. I am pretty sure it’s fine but would like some reassurance for peace of mind. Thanks.
Is this the same timing mark procedure for the Lexus GS430 4.3 V8 3UZ VVT-i ? Thanks! Looks easy enough.
I want to do this job but my timing belt snapped so I don’t have a reference when it comes to rotating the existing belt. What do you recommend? Should I just take it to a mechanic or can I accomplish lining up the marks?
Dont we usually replace the water pump and the timing belt at the same time? I just purchased a used 08 GX 470. The carfax says timing belt was done at 96k miles but did not mentions water pump at all/ Any thoughts anyone? Thank you
Sauer Sig from what I’ve learned in shopping for a GX470, typically the water pump AND timing belt are done together. Go to the Lexus website and check the VIN there, service history from dealer will be logged and fairly detailed
What do you do if the cams have jump? What’s the best way to reset them?
