- Did our video help you? If so, consider buying us a beer: bit.ly/3feE6tJ
In this video series, we show you how to replace the starter on the Toyota/Lexus 4.7L V8 2UZ-FE Engine. The vehicle we were working on is a 2008 Lexus GX470. In 2005, VVT (Variable Valve Timing) was added to the engine, and along with it, the secondary air injection system. The secondary air injection complicates the removal of the starter, mainly due to the #2 switching valves that bolt to the water bypass joint at the back of the engine. For 2UZ engines 2004 and earlier, you won't have the secondary air injection system and you'll have an easier time replacing the starter.
The size of the engine compartment you are working in can make a difference. I've seen a video of a guy doing this job on a Tundra, and he could actually get his hand with tools behind the engine to loosen the starter bolts without having to deal with the water bypass joint with the #2 air switching valves attached to it. You would be working totally blind to get onto the starter bolts with an extension and socket, but it looks like it can be done. We didn't have this option, because there was literally a 1/2" of space between the #2 switching valves and the firewall on the GX470.

Hang in there! You guys are the best for continuing to film even when frustrated. Can’t wait for part 2.
Thanks Richard. This job was a serious test of patience.
@@TimmyTheToolman I know this job was difficult but this is most likely the worst case scenario for all the people with the 2UZ engine. This video will help everyone.
@@richardsauer599 Yep, it will definitely help people on several levels. Just knowing what parts to buy in advance is a huge thing.
Apparently, from watching a carcarenut video recently, these engines had the starter placed in the middle of the engine under the intake for balance. These engines were certified for airplanes so balance was more important than anything else like ease of installation of the starter as it would be hanging off the end of the motor and a couple pounds on the edge of the motor makes it unbalanced. That’s also why these engines run so smooth. Pretty cool to learn that as a lot of people probably think Toyota just screwed up on the design. The carcarenut doesn’t know of this engine making it into any planes, but they were certified and capable of. Good stuff Tim, appreciate all the videos!!
Take care~
That's interesting about why Toyota put the starter there under the intake on the 2UZ-FE engine. Thanks for sharing that.
I have to admit I'm jealous of how successful the Car Care Nut's TH-cam channel is. But, even though the Car Care Nut guy's channel has way more subscribers and views of his videos, I would put our channel up against his any day when it comes to providing practical and detailed tutorials people can follow to repair, maintain and modify their Toyota and Lexus SUVs and Trucks. We also thoroughly document BIG jobs that no other TH-camrs will, like engine and transmission swaps. When other TH-camrs document these types of jobs, they skim over things or they make it a time lapse and provide very little detail.
I guess what I'm trying to say is I'm proud of the content we create on our channel. It's too bad what we do doesn't translate to more subscribers and more views. The channels that do much better tend to have more "For Entertainment Value" or "Basic Knowledge" built into their content, rather than practical tutorials like we create.
Anyways, thanks for the comment. I appreciate it.
@@TimmyTheToolman oh yessir!! 100%!!! I absolutely love your channel specifically for what yall document and show! It takes a lot of work to film the jobs yall do and then edit them out. Your channel will most certainly grow to his levels. Especially as the fifth gen gets older and more people find your channel.
@@TimmyTheToolmanPS you’re correct, NOBODY shares the detail that yall do and it’s helped countless people I’m sure. No need to be jealous of his channel size, yall are doin great things and are great people so yall will grow just as big.
@@KendrasEdge757 I appreciate what you said. Thanks!
@@TimmyTheToolman 🤙
Been there done that. I got rid of the entire SAIS system and installed a Hewitt SAIS bypass emulator kit.
Yeah, the Hewitt kit is a good way to go. I just can't advertise a cheat method on our channel.
this is the video i have been waiting for...
We're glad you wait is over.
Thank you for this video. I have an '03 4Runner with the 2UZ and as you stated, if you don't have that SAIP air system it is a lot cleaner. As I watched this video I went out and looked at my setup compared to yours and mine is a LOT more accessible. Although I do have the aluminum intake manifold and I think if I ever have to do the starter I will separate it and take it off in halves as it looks pretty heavy. Other than that I won't have to fool with any of that emission stuff. Thanks again, I love your videos!
Thanks for the comment Russell. That's good you don't have the secondary air injection. What an expensive and labor intensive pain in the butt it is.
when pulling the rock hard hose use a heat gun to soften it up and it slides right off without damage.
Great tip! That hose was crazy hard though… like a ROCK! Anyhow, thanks for the comment.

Killing it with sharing the 2UZ knowledge Tim. 🙏🙌. Thank you so much for this brother!
Thanks David and you're very welcome. Part 2 will be coming out soon.
It's a good video. But I removed the starter by unscrewing the starter bolts from below, without touching the antifreeze housing of the thermostat. And thus bypassed the fuss with the EGR system.
You must be working on a model with more room, like a Tundra. We did take a look at the possibility of reaching above the transmission to get at the starter bolts, and with the GX470, there wasn't enough room. If you did do this on a GX470 model, you must be a magician because we saw no access to get in there with our hands and tools.
@@TimmyTheToolman Yes, I unscrewed them from the bottom on the GX470, connecting all the extension cords that I have. But I did it all by touch, because the bolts are not visible. So I agree here, it's a miracle if you can unscrew the bolts right away. But after doing this kind of work several times, it already becomes easier, and now, on average, it takes about 15 minutes to unscrew these bolts
@@starter15ru21 Gotcha, you went over the top of the trans with a bunch of extensions. I'm familiar with that technique for removing bell housing bolts for the many transmissions I've pulled, but after analyzing how tight it looked, I didn't even think I could get my hand up there to direct a socket over the bolt heads. You're better than me, because the access looked impossible and that's why I removed the coolant neck/secondary air injection valve. Also, how you were able to get the bolts back in blindly is a small miracle. I believe you when you said you did it, but Thanh and I both agreed getting our arm and hand up there with the limited access was next to impossible. When I see Thanh's GX470 again, I'm going to take another look how I could have reached up there to access the bolts.
@@TimmyTheToolman If there was a video specifically with this car, I would be happy to help and show how we unscrewed them. But as for the blind bolts, we left the extension cords on the box after we unscrewed the bolts, otherwise if the bolt falls, it's very bad. Dancing with a tambourine will begin. I hope I was able to be helpful. But your version was also interesting. The very first time I took the starter off through the top, unscrewing the EGR bolts, and it was agony.
@starter15ru21 I agree the secondary air injection valve is a nightmare to deal with. That is a job I have zero desire to repeat, but it would definitely be easier the second time around now that I know the proper tool combos and access points to use.
35:47 that's what she said
Hey, you caught the joke. Good job!
Oh wow. Just for reference I have the same engine with my 2000 tundra, original starter and no issues.
Yeah, those starters can last a very long time. Eventually, it will have an issue. As a job you do at home, it's involved, but tolerable. Doing this job on a 4wheeling trip would not be ideal, and maybe impossible, depending on the tools you brought along with you.
Thanks for this video, very helpful.
You're very welcome!
So glad I have an 03. That looks like a nightmare to deal with the air pump.
It is a nightmare. If I got a Toyota or Lexus model with the 2UZ-FE engine, I'd get an earlier year without the stupid secondary air injection system and variable valve timing.
Awesome video
Thanks Jay. Part 2 will be coming out soon.
Hey Tim, thanks for all the great videos. I just cleaned my IAC and wow was it gunked up. I’ve seen your video on replacing the door lock actuator motors and was wondering if I had a weak one, would it prohibit me from unlocking/locking my doors with a key fob? My window switch for locks works fine beside the front right door making a squealing noise when locking. I appreciate your time and once again thanks for all the helpful info!
A weak door lock actuator would make it hard to unlock the door. When locking, gravity is helping the actuator so it's usually not an issue.
Hi Tim, I watched both of your videos on this topic and understand how much labor is involved in changing out the starter and the SAIS system. I have a 2004 GX470. Does this model year have the SAIS system under the manifold unit? You only mentioned that SAIS was introduced in 2005 and newer. Please advise or let me know where I should research to confirm. Thanks so much!
@hccvad591 Your 2004 shouldn't have the SAIS based on my research.
@@TimmyTheToolman Oh thank goodness! It looks like it is a nightmare to replace any of the SAIS components and the starter unit. Thanks for confirming!
The non VVTI 2UZ starter replacement is way easier right?
Yes, it's way easier. The secondary air injection switching valves makes the job much harder. Plus, there are more electrical connectors that can break.
Why did you replace the starter? Seemed like it started fine at the beginning of the video.
Thanh wanted to do it as preventative maintenance to avoid a failure on a trip. Because this starter replacement is so involved, it's not an ideal trail side repair.
How much time was this job total ?
Hard to say because we had to delay it a couple times for needed parts and we were filming. If you have all the necessary parts, you could easily do this job in one day.
36:50 What is that hose called ?
Open the video description by clicking on "more" to expand it. We provide the part number and link to all the parts used for this job. I don't know the specific name for the hose, but it's one of the air assist pump hoses. It's listed as the longer of the two hoses.
Timmy the Toolman. Could you please help me? I have a 2006 Sequoia Limited with 2UZ-FE. Can’t seem to locate the MAP sensor. Call Toyota parts department they told me to watch TH-cam and no one shows where it’s at. They just show MAF. Please help .
I don't think there is a MAP (Manifold Absolute Pressure) sensor on the 2UZ engine. You have a MAF (Mass Air Flow) sensor to communicate with the ECU how much air is entering the intake to then figure out the injector pulse to create the proper air/fuel mixture.
Wow thank you so much. It’s crazy because I contacted Toyota parts was informed that the part number 89421 and sitting on the manifold. Lol
@michaelconteh4947 Well, who knows, maybe the 2UZ engine uses both. I'm not 100% sure. It's just that they both do the same thing but in a different way.
Ok thank you so much
LOL. This replacement, must be whith remove vehicle body!
@@serhiymelnyk1766 It's a pain in the ass job, no doubt.
The SAIS system is ridiculous and Toyota should feel bad
I think it was done in response to the ridiculous smog laws. I don't think Toyota came up with it to torture us. I blame the idiot environmentalists more than Toyota for this ridiculous system that does next to nothing.
