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!
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!
I'm sure you saw it broke when he took the cover off. If not. Was it broken or was it a fuse, crank sensor. Really lucky. They didn't make the engine any different from one to the other.
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.
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.
@@peterl2017Peter, please tell me did the belt that broke was an Aisin belt? I’m getting ready to put on an Aisin belt this week. Please let me know. It’s scheduled for monday
@@JD-ij3wr No it was not, it was a Napa that ai believe is made by Gates. It was just slightly over the interval, but definitely original belts always last way way past. I would hope a really good aftermarket would as well. I have always heard good things about the Aisin parts. I would go that or one right from Toyota.
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-?
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.
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!
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.
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~
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!! 👍
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.
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.
@@95thousandrosesvalves can take a smack there are instances of over tuned engines where you can see the valves imprinted on the piston heads. A bent valve isn’t the end of the world either. But it is a lot more work.
I've heard the same as well, that non-VVTI do not experience damage during timing belt breakage. I have a 2004 GX470, just replaced the timing belt with an AISIN kit.
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.
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.
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.
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 !
My 02 4Runner just did this! It was warming up in the driveway and I came back to the truck stopped, and the smell of burning rubber. I broke down everything to get to the belt and it’s been burned all the way around due to the idler pulley bearings basically blowing out and seizing. I’m just wondering if in your case, did you have any compression on the engine when you tried to re crank it? Or did the belts just spin? I’m hoping the no compression I’m seeing is due to the belt just needing replacing and maybe it jumped time.
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!
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 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 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.
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 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 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
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).
I love your enthusiasm for saving this vehicle. What commitment to taking care of customers. I have a 2004 Sequoia and it has just over 200,000 miles. I have lots of miles to look forward to.
I am NOT a mechanic, but I think that what happened is that the vehicle was idling & the belt broke & instead of snapping immediately, the belt pulled apart slowly enough that the engine was virtually stopped when the separation of the belt was effected & the drag of the internal components stopped the final rotation. I had a belt on an interference engine break & I retimed everything , put on a new belt, & all was well. Had the car been on a highway at speed, it would have had a destroyed engine. Great video!
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 had a belt fail on an '04 Frontier while idling at a red light. Luck was with me - no damage beyond the belt. My mechanic got me fixed up. Since then I traded it for an '07 Tacoma. So happy for this lucky Lexus owner - it's a sweet ride.
Just had the timing belt replaced on my 06 tundra with around 76000 miles on it and the belt looked almost brand new no cracks and I could read all the print on the belt.
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.
I just recently bought a 2004 Lexus Rx330 have complete confidence in this vehicle for long road trips. My 2000 Toyota Tacoma Prerunner is my first and only purchased new vehicle that has always taken me on trails and off road trips And Back being the operative word. All work and upgrades done myself. My 1983 Tercel manual drive with AC 47 mpg! also terrific and still see it from time to time on the road. The miracle is Toyota.
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.
Thanks for Sharing. It just goes to show that just because the Timing Belt "Snapped" on an "Interference" Engine does Not mean that the Engine is Toast. Though the chances are more like the Engine is "Damaged" and possible "Totaled or Dead"; it is "possibly" worth checking into.
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!
The timing belt on my 2002 Sequoia snapped at 280k km; previous owner replaced it and kept on driving until I bought it at 346k. I drove it for a year and then put an OEM belt/water pump/cam and crank seals for peace of mind. Currently sitting at 376k and the 4.7 is still purring like a kitten. I love this engine
I've never owned one of these V-8s, however I had a 1991 Camry from new. I followed the recommended service schedule and periodically inspected the timing belt. At 202.000 miles some wear was apparent and I replace the belt. Fairly simple procedure and the cost was $17 at the time for a new belt. I have seen timing belts from this era that were original and the belt was in good shape at 200,000 miles.
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.
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
Amazing video Petr, great outcome and a demonstration that you are the Toyota master. It's great to see the old engine endure adversity and come back for more. It wants 500,000 I think.
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 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.
Happy ending, good for you for trying another belt to see if the engine would turn over and ultimately run. Makes me think the blown Sequoias with broken timing belts may be worth trying to save. Or at least the pre-vvti models like this from what I've gathered from the comments
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?
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.
I just did the timing belt on my 120k mile v8 2007 4runner. The belt was cracked and looked like it was about to break. I am glad I did it. The truck runs great and has been flawless in my 6 years of ownership.
@@thetruth8095 purchased in Madison, WI. The underside of the truck tells the story of a lifetime of Midwestern winters. No holes or anything like that, but it isn't pristine.
@@cjburn2758 Road salt is the enemy of these vehicles. You should consider treating the frame with rust converter and undercoating if you have not already.
I just changed my timing belt on my '04 GX this Summer. Well over 90k miles. on the old belt. Cracked but still intact. This was interesting. Thanks, Peter! Good luck to your client.
Absolutely love this video, Peter. Great job in getting this beautiful machine back on the road. Toyota/Lexus quality, amazing! Thank you and cheers my friend.👍🇨🇦🇺🇸
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.
AMAZING V8 reliability! I’m on my (2nd) Timing Belt with 200K on my 2UZ-FE on my 2005 Sequoia with AISIN KIT, which is the most reliable! DO NOT use other brands or they will break at only 80K when AISIN will go past 100K. I’m at 205,000 w/ oil changes every 5K with Full Synthetic Mobil 1 oil 5W-30. Only (8) more AISIN timing belts to go for One Million proven miles on 2UZ-FE.
no way that was a new belt installed, either that or the belt was made in Ch***. I replaced mine at over 100k and it was absolutely like new, no hairline cracks in it, nothing. I installed a new Toyota belt, no after market crap. Great to hear that the engine never got damaged, Toyota strong.
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...
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
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 would love to see a cross over with you and Care Care Nut.
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!
😂Could be a cheap parts😢
I agree
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.
Probably a cheap belt.
Or was it even replaced the last time ?
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!
That's good to hear because I have a 2001 Tundra
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.
Saw a video here on YT where a guy's timing belt broke on a LC100. They replaced it and engine was just fine.
@@donovanchilton5817 totally agree, the non-vvti are totally recoverable from timing belt breakage.

I wonder if that "70K" belt service was actually done. That belt doesn't look like it was serviced in the 2020's.
Good point. Shops should have to PROVE the belt was changed with photos.

We were all Hoping that you could Save that 4.7 Engine!!
I love your enthusiasm for saving this vehicle. What commitment to taking care of customers. I have a 2004 Sequoia and it has just over 200,000 miles. I have lots of miles to look forward to.
I am NOT a mechanic, but I think that what happened is that the vehicle was idling & the belt broke & instead of snapping immediately, the belt pulled apart slowly enough that the engine was virtually stopped when the separation of the belt was effected & the drag of the internal components stopped the final rotation. I had a belt on an interference engine break & I retimed everything , put on a new belt, & all was well. Had the car been on a highway at speed, it would have had a destroyed engine.
Great video!
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 had a belt fail on an '04 Frontier while idling at a red light. Luck was with me - no damage beyond the belt. My mechanic got me fixed up. Since then I traded it for an '07 Tacoma. So happy for this lucky Lexus owner - it's a sweet ride.
Just had the timing belt replaced on my 06 tundra with around 76000 miles on it and the belt looked almost brand new no cracks and I could read all the print on the belt.
will you be letting the next one go a bit longer?
Great job, I came across your channel and appreciate how you took the time to check the problem...Thanks for sharing
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?
Great little miracle! Speaks to what a great job Toyota does in design and quality! The owner must be very happy with the results.🎉
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.
I just recently bought a 2004 Lexus Rx330 have complete confidence in this vehicle for long road trips. My 2000 Toyota Tacoma Prerunner is my first and only purchased new vehicle that has always taken me on trails and off road trips And Back being the operative word. All work and upgrades done myself. My 1983 Tercel manual drive with AC 47 mpg! also terrific and still see it from time to time on the road. The miracle is Toyota.
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.
Thanks for Sharing. It just goes to show that just because the Timing Belt "Snapped" on an "Interference" Engine does Not mean that the Engine is Toast. Though the chances are more like the Engine is "Damaged" and possible "Totaled or Dead"; it is "possibly" worth checking into.
Amazing!😮
Wow I was always a believer in these engines. That's incredible.
Happy story!!
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!
The timing belt on my 2002 Sequoia snapped at 280k km; previous owner replaced it and kept on driving until I bought it at 346k. I drove it for a year and then put an OEM belt/water pump/cam and crank seals for peace of mind. Currently sitting at 376k and the 4.7 is still purring like a kitten. I love this engine
I've never owned one of these V-8s, however I had a 1991 Camry from new. I followed the recommended service schedule and periodically inspected the timing belt. At 202.000 miles some wear was apparent and I replace the belt. Fairly simple procedure and the cost was $17 at the time for a new belt. I have seen timing belts from this era that were original and the belt was in good shape at 200,000 miles.
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.
Wait...the 2nd timing belt gave out after less than 100k...but the first/stock belt went for over 300k? Help me understand this...damn...
My guess? 1)Very cheap aftermarket belt 2) If OEM belt, it was replaced with a used worn out OEM belt 3) If OEM belt, they never replaced it
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.
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
Sorry for your loss 😢
Amazing video Petr, great outcome and a demonstration that you are the Toyota master. It's great to see the old engine endure adversity and come back for more. It wants 500,000 I think.
Miracle absolutely
I replaced the timing belt on my 04 4.7 at 16 years , 65k. It looked perfect and seemed able to go a lot further 🎉
A lovely engine the 2Uz!
Peter, OUTSTANDING VIDEO and as USUAL, EXCELLENT, HONEST, WORK and SUCCESS, BY YOU!!! You are a LEGEND in the car mechanic world!!
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 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.
Happy ending, good for you for trying another belt to see if the engine would turn over and ultimately run. Makes me think the blown Sequoias with broken timing belts may be worth trying to save. Or at least the pre-vvti models like this from what I've gathered from the comments
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 wonder if everything related with the timing belt was replaced . Idlers, tentioners, water pump, pulleys, cam seals etc.
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.
I got one just like it, except mine is a 2005 with 185,000. What a miracle. I love mine. It is a real great 4x4.
I just did the timing belt on my 120k mile v8 2007 4runner. The belt was cracked and looked like it was about to break. I am glad I did it. The truck runs great and has been flawless in my 6 years of ownership.
What climate was your vehicle in? Was it hot or cold?
@@thetruth8095 purchased in Madison, WI. The underside of the truck tells the story of a lifetime of Midwestern winters. No holes or anything like that, but it isn't pristine.
@@cjburn2758 Road salt is the enemy of these vehicles. You should consider treating the frame with rust converter and undercoating if you have not already.
@thetruth8095 got cleaned up Blaster Surface Shield applied this summer.
@@cjburn2758 That’s great. PB Blaster Surface Shield is a great product.
Thank you Peter.
I need to borrow a line from Bob Weir on this one "I need a mircle everyday!!"
You da man!
Same thing happened to my wifes camry slapped a new belt on and it was fine.
did you put in a new belt after try with the used one?
I just changed my timing belt on my '04 GX this Summer. Well over 90k miles. on the old belt. Cracked but still intact. This was interesting. Thanks, Peter! Good luck to your client.
What climate was your GX in? Was it a hot or cold climate?
@@thetruth8095 the two extremes here in Western Canada.
@@kenzeller6518 Those frigid winters definitely have an aging effect on the rubber in these vehicles.
Absolutely love this video, Peter. Great job in getting this beautiful machine back on the road. Toyota/Lexus quality, amazing! Thank you and cheers my friend.👍🇨🇦🇺🇸
Topman Peter 👏
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. 👍
Thanks Peter! It's not a miracle it's a T.O.Y.O.T.A. My 2001 Sequoia 320k miles running great!
Wow, that's amazing no damage is done.
Bulletproof motor and reliable as was the 1,000,000 mile engine bulletproof Toyota
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.
Awesome Peter!!! You bring the best from vehicles
God Bless
AMAZING V8 reliability! I’m on my (2nd) Timing Belt with 200K on my 2UZ-FE on my 2005 Sequoia with AISIN KIT, which is the most reliable!
DO NOT use other brands or they will break at only 80K when AISIN will go past 100K.
I’m at 205,000 w/ oil changes every 5K with Full Synthetic Mobil 1 oil 5W-30. Only (8) more AISIN timing belts to go for One Million proven miles on 2UZ-FE.
no way that was a new belt installed, either that or the belt was made in Ch***. I replaced mine at over 100k and it was absolutely like new, no hairline cracks in it, nothing. I installed a new Toyota belt, no after market crap. Great to hear that the engine never got damaged, Toyota strong.
How is the oil ? Is it contaminated ?metal particles or shavings. Compression taken ? Results this is amazing , the engine works.👍
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 work very good outcome for the owner there.
Good one, thanks
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...
Nice work, absolutely love this channel. You are just one of the best guys on youtube.
Fantastic video!!!! Toyota/Lexus needs to see this fight haven’t already!!!! Again, great job brother. Keep it up!!!
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
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!
Graet video; and an extremeky lucky owner. Congratualtions, excellent work and a rewarding outcome. Thanks
