Lexus GX470 2UZ-FE Engine Broken Timing Belt - is it ruined?

High mileage 2004 Lexus GX470 with broken engine timing belt. Is it the end for this one?

[@Being_Joe]

I would love to see a cross over with you and Care Care Nut.

[@frankponte4031]

I've done a couple of 2UZ-FE timing belts on my previous GX470's. Always at or about 100,000 miles and they weren't close to looking as bad at that timing belt shown in your video. Something smells fishy if it was replaced ~ 70,000 miles. The 2UZ-FE is an engineering marvel. Bullet proof!

[@longnguyen-zu1qe]

😂Could be a cheap parts😢

[@PeterHernandez-lg2eh]

I agree

[@mark-wn5ek]

If it’s an interference type engine it surely isn’t bullet proof! Why they ever design and build such en-jeenz, I’ll never understand.

[@nononsenseBennett]

Probably a cheap belt.

[@jayhockley8841]

Or was it even replaced the last time ?

[@ronaldrussell5481]

So far just seeing the belt makes me question was it really changed 3years/75k miles ago? If so, what quality belt was used? Excellent video!! I have an '03 4Runner with the 2UZ/4.7L and am now more convinced that they are bullet proof! I hope not to put it to this test though!

[@skipdog77]

Previous shop - no way they replaced it! BTW - how old was the belt you installed? Did you put a new one on before buttoning everything back up?

[@scottmcdonald7577]

I'm the original owner of a 2001 Toyota Sequoia. My timing belt broke after just 70,000 miles on the replacement at freeway speed. I called the dealership and they told me the engine was toast! I took it to my mechanic and he said, I've had lots of luck replacing timing belts on the 4.7. He replaced mine and I have another 30,000 miles on that 4.7. Works perfectly. No oil burning, nothing. I know some people say these are interference engines, but mine wasn't and my timing belt broke doing 65 mph!

[@donovanchilton5817]

People will argue up and down but the non VVTI variants of this engine are not true interference. 1998-2004

That's good to hear because I have a 2001 Tundra

[@scottmcdonald7577]

Yep, don't put off doing your maintenance, but don't let a dealership tell you that you need to replace your engine if you break a timing belt.

Good point. Shops should have to PROVE the belt was changed with photos.

If they did the timing belt they probably used a Chinese belt. There are a lot of counterfeits out there. I got 150,000 miles out of my original timing belt on my Lexus.

[@peterl2017]

My father in laws that broke was done by me with a Napa kit and it broke at just slightly past the interval. We had just discussed that we should do it soon, but figured we had a bit of wiggle room, an OEM would go well past I am sure. Last time I used an Aisin kit. I believe some aftermarket belts would fail quite early.

[@o_leksandr]

Dude, this is absolutely amazing! It seems to me either non-OEM belt was installed… or the old belt wasn’t replaced at all-? I mean, come on, only 80k or so miles? PS: People who leave pessimistic comments probably didn’t watch to the end-?

[@lars277]

There are a couple videos in YT that 2UZ-FE engines got one million miles. Toyota bought the people new trucks and took the old ones back to study them. That says a lot about Toyota. Even if they did that for PR, that is some very good PR.

[@flight2k5]

Those rat bastards most likely didn't replace the timing belt. Most mechanics are shitbags! I'd never trust any of those scumbags unless it was the youtube owner of this channel! My hat goes off to an honest mechanic, one in a million! If you have to take your vehicle in to a mechanic install a hidden camera just so you have some recourse!

[@nononsenseBennett]

That's why consumer must INSIST that proof be supplied about repairs. A short video showing the belt OFF the engine while under replacement is all they have to do, while also providing old parts for inspection.

You can see the sadness on the dudes face as he’s explaining he thinks the engine is done. That’s crazy.

[@kusterflattail]

All hail whip cream head!!!!

[@paulapril]

Toyota recommends replacing the timing belt on The 2UZ-FE, (4.7 V8) every 90k miles. I replace mine every 120k miles. Belt comes out looking gently used. I've never seen a timing belt on a Toyota/Lexus fail without going at least twice over the recommend replacement interval.

[@efil4kizum]

This belt failed at less than interval rec? ... Only 76k miles onit

[@paulapril]

@@efil4kizum I saw the belt in the video. That is not a belt that has olny 76k miles on it. More like 376k. Something else is at play. Just like in the aviation world, there are multiple factors that lead up to and contribute to a failure. Never just one.

[@thyslop1737]

Wanna say I read somewhere on KZbin, that a guy had a Toyota with a 4.7 liter do not know if it was a Tundra or a LX or GX, do not remember, but he said that he had 270k miles and had never changed the timing belt.

[@Beauloqs]

Same as, first time with mine was 190k kms and I just did it again @ 405kms. Belt could have done another 50k...... I live in northern Canada, this truck gets used.....

[@jesusfimbres2636]

I heard was that if the engine is VVTI it will damage engine if belt breaks. If it does not have the VVTI it won’t hurt the engine if it breaks. Awesome video brother!! 👍

[@seanwise7464]

I’ve come across this argument as well while researching mine, still no solid answer I can find, but this video hints it may hold some truth as that engine did not have the vvt cams on it and it survived.

[@95thousandroses]

I've heard the same . crazy how hard it is to find out for 100% though. Shouldn't be that hard to find out. Do the pistons of a non vvt 4.7 ever at all reach the length of the valves at any position? Just goes to show how much bad info is on the internet.

They probably used a counterfeit belt from China thinking it was an original. No way that an original belt would snap at 70k miles.

[@marcodarko6941]

Isn't that something. Off the subject of the timing belt, I just bought from the Toyota dealership new wiper blades for my front and rear windows. Took them out of the package and noticed how chintzy and flimsy (noticed they're made in china, go figure) they feel compared to my old pair that feel more substantial, a better quality. I didn't put them on and I am currently considering taking them back to the dealer parts department for a refund and switching brands. I have always used Toyota oem blades and get a full years use out of them, about 10k to 12k miles. And for nearly $100 for three blades.. nope, not anymore.

[@edjaik]

Thanks peter, for showing those engines reliability

[@dongeorge4037]

It is absolutely unbelievable that you can freely rotate the crank. And I also cannot believe that it's running. And I agree that a miracle occurred - the owner purchased a Toyota.

[@johntheaccountant5594]

That belt was not faulty, it was just never changed and worn out and stretched over time. No way had that genuine Toyota Belt only done 70,000 miles. Did the customer tell you when (how many miles) it has driven since the belt was last changed? Customer's tightness with fully servicing properly has cost him now. He was very lucky on this occasion.

[@mazdarx7887]

Replaced broken belt with a used belt? I wonder how many interference motors have been replaced needlessly? This , and I'm sure others have had similar experiences, because the mechanic didn't just throw in the towel because of a broken timing belt on an interference engine. Good job, it pays to be absolutely sure before buying things

[@sheratanarietis8787]

This video was so sad to watch as a fellow 2UZ-FE owner... but such a huge smile and joy came at 21:17 2UZ-FE absolutely the greatest motor built by Toyota. I’m certain the owner will give the clear for further testing but this hints at the theory I read many years ago that the non-VVTi versions have a chance of surviving timing belt failure. The owner gave this motor plot armor when they said they wanted it to reach half a million miles! 500k miles is the goal I gave mine many years ago. Currently at 419k miles and the timing belt system has only been serviced twice (the last time at 359k miles and that service was overdue for 250k+ miles and the belt looked in quality condition I kept it!) Absolute workhorse of an engine doesn’t give up even if you wanted it to!

[@donovanchilton5817]

They were right. The non VVTI variants had a cutout in the cylinder head that prevents it from smacking a valve if the belt breaks at speed. You’ll get arguments here and there; it’s a contentious subject amongst Toyota people.

[@MarzNet256]

Wow. It's like all rotating components slowed down together in a synchronous way and came to a stop, maintaining timing down to 0 rpm. Betcha engine was at or close to idle and not accelerating or decelerating (stable rpm).

Thank you for this video. It is very helpful to anyone who wants to do this job. I am not trying to promote another channel on your channel, but wanted to mention that there is a very detailed two part series about replacing the GX timing belt on the Timmy the Toolman channel. I mentioned your channel on their video and I wanted to reciprocate so that anyone who has watched this very good video can also see another reference about this job. Best to you and thank you for this video. As a 2004 Sequoia owner, this is a very helpful video.

[@marcodarko6941]

That's awesome. Not a bad looking ride for being 20 years old and nearly 400k miles. If the engine was toast and the body and frame was all in good shape, being the owner of it I'd consider a lower mileage engine swap.. glad it worked out for the owner.. next stop 500k and beyond!

[@thxcolm]

That was the biggest rollercoaster of emotions I've ever seen on this channel. I have a long way to go on my 2uzfe, only at 261k.

[@crautoguy8384]

The trick with those engines is also to advance that camshafts one tooth When installing the belts with the crank shaft at 0 all the slack on the tensioner side that way when you pull the pin on the tensioner it will pull the camshafs back into phase and all the marks will lineup I can't tell you how many times I've seen this done improperly and there will be one tooth off

[@ZacCostilla]

The pure joy, and even giddiness that I hear as you describe it as a miracle made me smile to the depths of my soul! I have an ‘05 LX470, with almost as many miles, and my goal is also a half-million miles. And this video gives me hope that I can get there.

[@seanwise7464]

I finally replaced my factory timing belt on my ‘07 VVT-I 4.7 at 170,000 miles. Old belt still looked good on removal but I was definitely taking chances. Water pump was definitely leaving evidence of leaking for awhile.

[@takeshi1242]

A lovely engine the 2Uz!

[@LAactor]

Excellent video and good luck for the owner. Absolute tank. Wonder what brand the bad timing belt was. Shocked it only lasted 75k mi. Gates? Maybe even worse. We all know you know from helping the boxer customer do not cheap out on belts. Happy ending. I live for your videos like these. Repairs with a successful happy ending. Even if it had low compression it starts and runs so I would keep it even without a valve replacement job. Hopefully it did not kiss the piston too much or at all. We don't want heat cycles to make any weakened valves become known later down the line. Tell him to drive gently for some time after just to make sure. If a valve drops into the cylinder make sure he knows to stop the car immediately. It would be like shrapnel in the explosions of war in the detonation area.

[@peterl2017]

My father in laws broke on his 2002 Tundra, he was pulling a trailer and on highway. Towed it here, it wrecked the crank sensor wheel but that was it, replaced the belt and away it went just fine. I have replaced everything once again since then, but likely 5 years since it broke.

[@kineticsurf]

Great video Peter. About to do belt & pump on my 2003 4runner 2uzfe. Is the Aisin belt & pump kit comparable to the Toyota kit? I feel as though they are the same thing made at the same factory. What is your opinion?

[@FantaLaStrada]

I just replaced my 93 toyota pickup timing belt/water pump using the aisin kit. The hydraulic tensioner looks exactly the same and the water pump is exactly the same. The only difference is that where on the old toyota water pump it says toyota on the aisin one the toyota lettering is ground off. I'm thinking it is done just so it can't be sold as an original toyota water pump. Not sure about the other pulleys and the belt being the same. Sorry I don't have experience with the 2uzfe kit, but thought I would at least tell you about my experience with an aisin kit.

I actually prefer timing belts over chains. They are usually simpler as cheaper to replace, no issues with skip timing due to hydraulic tensioners. Although chains are technically stronger, what usually fails are the guides as the tensioners.

It surprises me that youre surprised, i cant count how many interference timing belts ive seen break but no engine damage. on the other hand ive seen plenty bent valves, find out how many valves give them a quote and pull heads. The mechanics need to have hope and be very careful putting the belt back on so they dont bend valves during that process because they are careless.

[@waldofaldo1908]

It wasn’t ruined because the 4.7 is not a true interference engine. Yes it is labeled that way and it is possible to have valve damage but very rarely if ever does that actually happen. If you scour the internet and find stories about broken ones on this engine almost none of them turn out to be any extra damage. My Toyota mechanic believes it is not a true interference engine in that regard either although the maintenance process is the same. Now the 3.3 v6 for example if a timing belt broke on that it’s curtains no matter what.

[@jessethompson354]

It is interference, but it depends on what your VVTi is up to. The non-vvti version of this motor is non interference. If you break your belt just basically idling down the road at 30 mph through town there is a good chance you CAN change the belt and be ok. It's when the vvti starts changing the timing that this engine becomes interference.

[@waldofaldo1908]

I have a brother that had his break on a 2006 sequoia that was vvti when he was going down the Highway. Nothing was damaged and it was the original belt with around 230,000 miles.

As long as your 4.7 is NOT VVT version which I believe came out in 2004, maybe 2003, then it does not have the cam phasers and from what I have read and understand these early non iForce versions actually are not interference. The VVT 4.7 is going to be interference. However, on my 2000 tundra I will change the belt and water pump at 100k miles no matter what and I will only buy the Aisin kit (a Toyota partnership in Japan that produces for Toyota manufacturing several parts including the tundra transmissions). When I receive the kit I will also double check it all says Aisin and “made in Japan.”

I did want to ask if you just left the old used belt in or did you put a brand new one? Did you replace anything else? I would have just put in a new belt and called it good.

Yep, the timing belt should be changed every 60k miles, or exactly what it says in the owner’s manual. Luckily I have the timing chain in most cars I’ve owned. Change the belt, and read your owner’s manual.

Outstanding!! Just don't understand why the belt broke a 70+ thousand miles but worked out great for the owner very lucky man. What a miracle.

[@MrCalifornia1234]

That previous belt was definitely never changed.

[@RandyBsae]

Agree with many that the belt was never replaced but the customer was charged for it. My timing belt on my 2UZ-FE replaced at 125K mi looked in way better shape than that one. @toyotamaintenance -- What brand was that broken belt? Gates?

[@michaelt1349]

Was it confirmed that the snapped belt was a genuine Toyota OEM belt?

[@Donfreddy92]

Toyotas never fail to amaze me. Broke timing belt on my 01 sequoia with 220k on the clock . This video gave me a lot of hope so I took the gamble threw a new belt on and she lives on. No misfires , baby runs like new !

[@andrenj1970]

Not a miracle, as on toyota forums it says: Non VVTI 2UZFE engines survived broken belt no problem. Strange thing is why pretty new timing belt with not too many miles snapped hmm.

[@leehall5447]

No way that belt was new, it looks like it has 200k plus on it, recently just had my timing belt replaced on my 2002 Toyota Land Cruiser and the belt has 100k miles on it and it looked relatively new

Many years ago Ford had an 1800cc CHV Engine. I have had two on which the cambelt snapped. Each had new belts installed and started. Each ran ok emitting a ting ting as a valve had just been tipped after several minutes the noise disappeared, both went onto do large mileages before rust took them. My mk1 MX5/Miata 1800 has a non interference engine whats so hard in the design that it can't be applied to all gas engines ?

[@steveb6371]

I wonder if that belt was an OEM Toyota belt or a cheap aftermarket belt. I agree with other comments made. Was it never changed previously but customer was charged?

[@crautoguy8384]

I think the customer got ripped off Never seen a factory Toyota belt fail Unless it had oil contamination And I've done those 47 timing Bells when they've had over a 150000 on them That was crispy and a time bomb but didn't break And I don't think those are interference engines. Always been a subject of confusion for me because it It's different in different places you look on the internet or in manuals And I put belts on them when they've been broken and they ran fine also

[@crautoguy8384]

Not sure about the 4.7 but in the beginning days of the 3.4 witch is none interface the service interval for the the time about was 60000 then they increased it on later model years to 90000 So I do them at 90 thousand for all of my customers and I always replaced the tenchionr idler bearings and and water pump Customer does not want to do those I do not want to do the job. I have a feeling that someone put just a belt on that thing left the original water pump tensioner and idler pullys probable cousethe problem I thought the 4.7 was non-interference. But in any case I would go ahead and put a belt on it and see what happens I'm had engines EOK if the belt breaks on startup. That's going down the road at high-speed it's usually trash.

2UZFE NON-VVTI IS NON-INTERFERENCE: VVTI IS INTERFERENCE. NEVER EVER EVER USE NON-OEM TIMING BELTS STICK TO OEM OR MITSUBOSHI. ANY GATES, CONTINENTAL ETC., CAN RUN MAX OF 50K MILES. OEM OR MITSUBOSHI CAN DO 150K MILES.
