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!
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!
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!
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.
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-?
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.
Here are my speculation about this case...the timing belt wasn't changed by the garage, it was over stretch last time it was changed, bad quality part.
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.
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.

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!
Gotta love Toyota!! I don’t think that timing belt job was actually done. Absolutely amazing! Lucky he’s got you to do this as the other shop wanted to just replace the engine. Miracles do happen! God bless~
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 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.

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.
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.
I like to know the service history of this car who changed the belt and what brand, it is crazy if someone replaces the belt with a generic one if the engine is interference
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
I'm so happy the engine is good because that car looked new. That belt should not have snapped with that little mileage. I wonder if somebody pulled a fast on and didn't change it or it wasn't a OEM belt.
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).
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.
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?
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.
@@jeradmiles1956 Exactly. Plenty of newer Toyotas with rattling chains due to tensioners. That's why I'm all team belt. Even a DIYer is able to replace it without multiple special tools or having to reseal the front cover.
I don’t know, I think they are both good. My sisters 09 LC 5.7 had 431k on it at Christmas, when we were visiting. Only thing besides regular maintenance it’s only needed water pump replaced twice. Other than the engine has never been open.
Wow! That broken belt looks too old to have been replaced 70,000 miles ago unless it is a cheap after market belt. Are you able to tell if the broken belt is a genuine Toyota part? It may be the original or second belt. Very interesting!
I picked up a 2001 tundra with 375,00 miles a couple years ago for $2200. Same engine, broken timing belt while running. Replaced belt, did leak down test, cylinder pressure test - all good. Started it up and had a misfire. Replaced coil, ran like a top. Did the full timing service and a week later got a catalytic converter code and replaced the cat.has run perfect ever since and now approaching 400k miles.
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.
Lot of rain in your area now. The trick they call about #atmosphericriver but ypu are still the sunshine in this customer's cloudy day. If this is an absolute miracle and you like miracles. Does that mean you have performed many miracles? Then I must say you have to admit you are a miracle worker!! And that's why I am here for it. As we all are.

I wish you reduced pain on your thumb.
Original belt or a cheap aftermarket belt, I try to alway use toyota parts. The non VVT 2UZ-FE motor may not be an interference motor, or so I have been told. The 2004 GX is a NON-VVT motor so it may not be an interference motor.
I have 2004 Tundra but I changed my timing belt last year. Whew! My friend bought a used engine and is back driving his 04 Tundra. Good job wow!! Thanks to you he lucked out. 🥇
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.
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.
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. The previous owner said he changed it before but it was definitely original. I have heard of the vvti making it a true interference as well but have yet to see it. Maybe just dumb luck lol.
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 !
So, a few things about all this, 1>Peter said the owner was "driving around town" which means a much lower engine speed than if on the freeway...IMHO that is probably what saved the engine. If the owner had been out on the freeway, then goodbye engine. 2>the timing belt Peter pulled out of the engine does not look like a 3 1/2 year-old, 76000 mile belt. Wondering if the belt was actually replaced as claimed the last time the vehicle was serviced? And what was that god-awful knocking at 13:50 when he started the engine?
i just had mine replaced at the dealer on the same engine. 2008 tundra. How can I easily check that it is new? They didn't put a label showing the replacement date.
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.
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!
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.”
Our shop uses the Aisin timing belt kit. The packaged parts are Made in Japan and we’ve never had an issue with their timing belt kits. We use the Toyota or Honda OEM seals and other components not in the timing belt kit.
I just completed the timing belt on my 2002 Sequoia, no record that if was ever done, vehicle has 208k miles. I got concerned when the serpentine belt snapped so decided to do all pulleys and belts. I used only genuine Toyota parts, $1000, but I trust it to last at least another 100k. I don't understand why anyone would use non genuine toyota timing belt for this labor intensive job. PS my 208k timing belt looked better than the one here that snapped...
Great story. What can we conclude? Are there degrees of interference?I just did a fell timing belt kit replacement on a 3.4 V6 in a 4R with the original everything with 257000 miles, 25 yr old 4R!!! The belt had a few fine cracks but all the other components were OK. More than 150000 miles past replacement. I had a full Aisin/Toyota kit so I put it in and removed perfectly serviceable parts.. 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.
This is not possible. If it was truly an interference engine the pistons would hit the valves causing catastrophic damage like bending & smashing valves. It doesn't matter how good the quality of the engine is there is no turning back from a broken timing belt.
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?
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
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.
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?
No you got lucky, it broke with all the valves were down. Rare but it happens. All the Toyota V8 with timing belt are interfering engine, the repair manual never lies. 23 years Toyota Master Technician. If it had just lost some teeth on the belt, engine would have been toast. I done so many before retiring, I couldn't even think how many I done. Not sure why they didn't even look at it before checking it. I never use the starter, socket an pull handle, real slow. If it stops, checked the oil, if coolant in oil pan. It has what we call a cylinder door, where ever we find the two snapped off valve s. But hey what do I know.
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 ?
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.
Why are these OEM belts breaking so early. Original belts hold up at twice the milage and longer. Is there a manufacturing defect with these belts. I know the recommended replacement schedule. I just find it interesting these belts are failing so early. Just a curiosity of mine. It is just something I do not see happening often. Thanks for the video love your channel.
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
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.
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.
Peter does that really look like a timing belt with only 70K on it? No, that timing belt was not changed as I've seen timing belts from Toyota with over 100K that looked much better than that one. Also I thought most of Toyota engines were Non-interference
Thank you for sharing the happy story. I also would like to know what the heck happened to that timing belt at only 70k Were you able to tell what brand belt was used?
There's an old joke my first boss told me 26 years ago Not very funny but the difference between a Doctor and a mechanic is doctors get to Bury their patients mechanics have to bring them back from the dead
Even if they had to put a new engine that’s not too bad considering getting another 600k km’s. This is why this engine has the reputation of making 500k miles I guess. I hope Petr put a new timing belt while he was at it.
The early 2UZ-FE were not interference engines were they? I thought the interference engines came in in 2005. Worth some research. Only a non-interference engine makes any sense for this repair.
I don't know, but that timing belt looked a little to worn out for being just a few years old. I have to question if the shop who claimed they replaced it last time actually did.

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).
Did you put a new timing belt on or leave the used one used for testing on??
Looks like he leave the used one. lol Should have replace the water pump too.
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.
I just bought a 2005 GX470. The belt was replaced by Lexus 20k miles ago but that was 9 years ago. Is age a problem?
Yes ! I would look at it at least to see the condition
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?
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.
Why not just boroscope the engine? Just curious
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.
Totally agree, and several of Toyota's most durable motors happen to be timing belt motors too (2uz, 5vz)
Only on BMWs and Audi lol, on most car chains are lifetime
@@jeradmiles1956 Exactly. Plenty of newer Toyotas with rattling chains due to tensioners. That's why I'm all team belt. Even a DIYer is able to replace it without multiple special tools or having to reseal the front cover.
@@gianfrancoa Completely disagree. Know plenty of cases the chains needed to be replaced even below 150k.
I don’t know, I think they are both good. My sisters 09 LC 5.7 had 431k on it at Christmas, when we were visiting. Only thing besides regular maintenance it’s only needed water pump replaced twice. Other than the engine has never been open.
I thought I heard a loud knocking noise when you first started it,, but in the end sounded nice and quiet.
Wow! That broken belt looks too old to have been replaced 70,000 miles ago unless it is a cheap after market belt. Are you able to tell if the broken belt is a genuine Toyota part? It may be the original or second belt. Very interesting!
I picked up a 2001 tundra with 375,00 miles a couple years ago for $2200. Same engine, broken timing belt while running. Replaced belt, did leak down test, cylinder pressure test - all good. Started it up and had a misfire. Replaced coil, ran like a top. Did the full timing service and a week later got a catalytic converter code and replaced the cat.has run perfect ever since and now approaching 400k miles.
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.
I'm under the understanding that the non 4.7 VVT will usually be fine after timing belt breaks. The 4.7 VVT are usually toast.
I know your the Toyota expert. But my suggestion would be the use of a Articulation Bore Scope through each spark plug prior to cranking it up?
No way that's a 3 year-old belt.
Resurrected from the dead.
Bulletproof motor and reliable as was the 1,000,000 mile engine bulletproof Toyota
That Bell has more than 70000 miles on it. I've changed them all the time. I've seen him with a 100000 that looks better than that.
Lot of rain in your area now. The trick they call about #atmosphericriver but ypu are still the sunshine in this customer's cloudy day.
If this is an absolute miracle and you like miracles. Does that mean you have performed many miracles? Then I must say you have to admit you are a miracle worker!! And that's why I am here for it. As we all are. You show us many things we dont know, I want to help teach in return to make us all better. Geyser sounds like "guy"zer. I like Crystal Geyser more these days. Arrowhead water tastes heavy now. I think the water aquifer is drying up. Have a fantastic day my friend. Stay warm. I am glad ypu bought the Gerry Costco item for yourself. You never buy thibgs for yourself. I wish you reduced pain on your thumb.
Original belt or a cheap aftermarket belt, I try to alway use toyota parts. The non VVT 2UZ-FE motor may not be an interference motor, or so I have been told. The 2004 GX is a NON-VVT motor so it may not be an interference motor.
Correct.
I have 2004 Tundra but I changed my timing belt last year. Whew! My friend bought a used engine and is back driving his 04 Tundra.
Good job wow!! Thanks to you he lucked out. 🥇
I have one of these engines at 220k miles in my ‘03 Tundra. Ready for a new belt this year. I approve of this outcome!
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.
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.
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. The previous owner said he changed it before but it was definitely original. I have heard of the vvti making it a true interference as well but have yet to see it. Maybe just dumb luck lol.
@@waldofaldo1908so did it run after new belt ?
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 !
That truck looks amazing for almost 400k miles. Wonder if they used an OEM belt previously. I suspect no.
Wow! That guy is lucky. I hope he gets his half million miles on it. 👍
So, a few things about all this, 1>Peter said the owner was "driving around town" which means a much lower engine speed than if on the freeway...IMHO that is probably what saved the engine. If the owner had been out on the freeway, then goodbye engine. 2>the timing belt Peter pulled out of the engine does not look like a 3 1/2 year-old, 76000 mile belt. Wondering if the belt was actually replaced as claimed the last time the vehicle was serviced? And what was that god-awful knocking at 13:50 when he started the engine?
The 2004 is not a interferance engine, that is the vvt later motor.....
Was thinking about taking my 04 sequoia to you and having this job done what would it cost?
Petr, I wonder if Columbo is available to get to the bottom of this mystery. 🤔
If Columbo isn't, I think Kojak might be. Who loves ya, baby?
"Miracle just happened....I can't believe it!" LoLoLoL....I love it! Thats why I drive toyotas😍
i just had mine replaced at the dealer on the same engine. 2008 tundra. How can I easily check that it is new? They didn't put a label showing the replacement date.
Hope you asked for the used/replaced belt and parts that were replaced along with the service 😮. Just a thought.
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.
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!
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.”
Our shop uses the Aisin timing belt kit. The packaged parts are Made in Japan and we’ve never had an issue with their timing belt kits. We use the Toyota or Honda OEM seals and other components not in the timing belt kit.
I just completed the timing belt on my 2002 Sequoia, no record that if was ever done, vehicle has 208k miles. I got concerned when the serpentine belt snapped so decided to do all pulleys and belts. I used only genuine Toyota parts, $1000, but I trust it to last at least another 100k. I don't understand why anyone would use non genuine toyota timing belt for this labor intensive job. PS my 208k timing belt looked better than the one here that snapped...
Great story. What can we conclude? Are there degrees of interference?I just did a fell timing belt kit replacement on a 3.4 V6 in a 4R with the original everything with 257000 miles, 25 yr old 4R!!! The belt had a few fine cracks but all the other components were OK. More than 150000 miles past replacement. I had a full Aisin/Toyota kit so I put it in and removed perfectly serviceable parts..
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.
This is not possible. If it was truly an interference engine the pistons would hit the valves causing catastrophic damage like bending & smashing valves. It doesn't matter how good the quality of the engine is there is no turning back from a broken timing belt.
Amazing. Can't get that kind of luck from any German/European/Big 3 cars.
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?
Toyota, just amazing! Even their interference engines are invincible, I wonder how much "Interference" really is there?!
Wow! Non VVTI 2UZFE I think it will survive when timing belt breaks.
I wonder if everything related with the timing belt was replaced . Idlers, tentioners, water pump, pulleys, cam seals etc.
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
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.
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?
No you got lucky, it broke with all the valves were down. Rare but it happens. All the Toyota V8 with timing belt are interfering engine, the repair manual never lies. 23 years Toyota Master Technician. If it had just lost some teeth on the belt, engine would have been toast. I done so many before retiring, I couldn't even think how many I done. Not sure why they didn't even look at it before checking it. I never use the starter, socket an pull handle, real slow. If it stops, checked the oil, if coolant in oil pan. It has what we call a cylinder door, where ever we find the two snapped off valve s. But hey what do I know.
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 ?
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.
Amazing!😮
Why are these OEM belts breaking so early. Original belts hold up at twice the milage and longer. Is there a manufacturing defect with these belts. I know the recommended replacement schedule. I just find it interesting these belts are failing so early. Just a curiosity of mine. It is just something I do not see happening often. Thanks for the video love your channel.
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
How is the oil ? Is it contaminated ?metal particles or shavings. Compression taken ? Results this is amazing , the engine works.👍
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.
That belt has way more than 75,000 miles on it
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.
This is not 75k thousand miles belt .I replaced it in my sequoia when it hit 136k and it looked 10 times better .That poor owner was scammed 😢
Peter does that really look like a timing belt with only 70K on it? No, that timing belt was not changed as I've seen timing belts from Toyota with over 100K that looked much better than that one. Also I thought most of Toyota engines were Non-interference
“Guys, I don’t know what is happening.”
😂😂😂
Thank you for sharing the happy story.
I also would like to know what the heck happened to that timing belt at only 70k
Were you able to tell what brand belt was used?
There's an old joke my first boss told me 26 years ago Not very funny but the difference between a Doctor and a mechanic is doctors get to Bury their patients mechanics have to bring them back from the dead
Even if they had to put a new engine that’s not too bad considering getting another 600k km’s.
This is why this engine has the reputation of making 500k miles I guess.
I hope Petr put a new timing belt while he was at it.
The early 2UZ-FE were not interference engines were they? I thought the interference engines came
in in 2005. Worth some research. Only a non-interference engine makes any sense for this repair.
I don't know, but that timing belt looked a little to worn out for being just a few years old. I have to question if the shop who claimed they replaced it last time actually did.
If I was the vehicle owner, I would go back to the shop that allegedly did the last timing belt job with this video and demand my money be refunded. 🤬
What a Very Entertaining Video Peter
We were all Hoping that you could Save that 4.7 Engine!!
Interference engines do not belong in machines sold to the public. I can see race cars where every 1/2hp is important. It's engineered failure
I have 202,000 on my 01 tundra with 2uzfe. I hope to make 384,000 like this one.
That does not look like a belt with 76K miles. It may also be a cheap non-toyota belt. Always go with OEM with the belt
This is great news!!! Simply amazing
2UZ-FE-keeps running perfectly out of mere habit.
