Why you MUST replace timing belt frequently

[@thechuckster6838]

I changed the original timing belt at 144K, 6 years ago. I had bought the truck used with 121K. When I removed the original belt, I could have re-installed it and driven it another 100K miles. The original belt was in very good condition, even at 144K! I bought the aisin kit that includes belt, water pump, pulley's, hydraulic tensioner, cam seals and sticker. So far, it has 62K since I last changed the belt and that Mitsoboshi belt still looks like new. I will drive it another 20k and if the engine is still in good shape, I will do the job again. The truck has 206k miles and it still runs like butter with no oil usage and no coolant loss. That 3.4 engine could be the best engine that Toyota has ever made.

[@tylermartelle7041]

I did my 2000 4Runner August of 2023, it had the original belt and waterpump, pump had 07/99 cast into it and wasn't leaking. Belt was severely cracked, 205k and 24 years old I couldn't believe it.

[@perpetualgrin5804]

I changed the belt at 110km, belt was fine tensioner gone.😅

[@efil4kizum]

@@tylermartelle7041 Bizarre!

[@squidwardtentacles578]

Nice! Hey does yours tick at all at a warm idle? Mine does, idk if it's just how the engine sounds or if I need to adjust the valve shims

[@niacal4nia]

The newer EPDM rubber Timing belts introduced around year 2000 last twice as long but mechanics don't mention it for profit. My EPDM timing belt is over 20 years old and still looks like new. EPDM belts don't crack but shed rubber. Gates and Contitech sell them.

Thank you for another excellent video The number one takeaway I get is Stick to OEM parts For anything important Like a timing belt

[@jonathanratliff4780]

REAL!!

[@aliendroneservices6621]

Stick with OEM parts, period.

[@czechmate6916]

I inherited my mothers 2003 Camry she bought brand new it had 34k miles in 2019 it has the V6. I had my mechanic replace the timing belt and water pump kit from Toyota it now has 40k miles on it. I’m on a fixed income and have to make it last because I can’t afford a new car and this car is just like brand new still. I love watching your videos it’s nice to see someone that dedicates their time to one particular brand besides the dealer. I get a lot of important information from you.

[@z06rcr]

I used the Mitsoboshi ( not Mitsubishi) belt on my 4Runner .. changed at 105,000 miles and looked new when I replaced it at 210,000 miles.

[@Jimmyky77]

Don't Cheap Out on your Timing Belt Kit, get the OEM (Asin) if you plan on keeping Toyota for the Long Term.

[@flir67man84]

Did my wifes 1994 v6 3.0 timing belt at 210.343. It had 100k on it. Looked fine but did it anyways. aisin waterpump and tensioner. Eastcoast usa

[@johnberry2877]

As a former skilled trade’s contractor who worked in many GM factories throughout Michigan. I strictly forbid my family from driving any GM products. Great Video and advice on Toyotas 👍. You cannot beat the attention to detail, quality and precision these 🇯🇵manufacturers put into their products. I will never trust my families safety to any GM 💩.

[@keepingup2952]

Change the idler pulley too. I'll bet it is binding from bearing wear when it heats up and it's melting and wearing the top side of that belt, or it even could be the last guy over-tightened the idler pulley bolt, causing it to bind.

[@bigdaddymak1439]

Yes he'll change the idler but the bolt doesn't hold tension on the bearing.

[@vaughnc1786]

I would like to see you do a full video on how to do this job on the 2001 - 2005 Camry/Avalon.

He got every penny worth out of that belt. That is a testament to the LUCK of that owner.

Petr, It brings a tear to my eye when it see a Tacoma made in California, USA like this one. 😢

[@williameddy7217]

Great Video Peter.. I am a Tacoma owner and find this videos extremely helpful!!! Thanks

[@paultruesdale7680]

Great video, lots of great advice. Thank you Toyota for going with no interference while using belt driven cams. Any engine design with interference should be using chain driven cams.

[@annettesurfer]

I'm lucky my old econobox 2000 Toyota Echo has a timing chain rather than a belt. I guess that's something I'll look for in my next Toyota.

[@ckerce]

Thank you, Peter! It will be time to change the belt on my 05 Tundra soon (less than 35K miles!)!

[@adrianw3985]

The belt is dry rot. I'm surprised it didn't snap.

[@davidwashburn6388]

I have an 03 tacoma with the V6 just like this and have nearly 400k miles and I believe it's the factory timing belt on it. Got the truck when it has 113k on it. I'm just going to wait for it to either break or I come into a lot of money. This is one job I don't want to try myself

[@GraemeRobinson]

I have a 2NZ-FE so no timing belt but I find this informative nonetheless, thankyou.

[@thekerm8470]

I watched the whole video and the Tundra wheels comment at the end made me laugh. You are such a tease. I so want to see that Tundra be done even though I don't own one, but seeing it completed it will be like admiring a work of art.

[@tikitavi7120]

Got mine coming up this summer. Already done it once so I know what to expect. Check those fan clutches and the fan bracket bearing as well. I had the bracket bearing failing on the first belt change at 90 thousand miles. Supposedly that is a rarity but it does happen.

[@efil4kizum]

i have heard and seen pics of that failed fan bracket bearing and the damage that it can do... but i would have NO clue what sound that might make to warn you beforehand to get it taken care of ASAP

[@zombiewarengineering]

I just did this job on my 2003 Tacoma and my belt looked in similar condition. I highly doubt the previous timing belt job from previous owner used OEM belts and parts.

[@fatbastardwithabeard]

I came here to ask if the belt was identified by brand when the repair was done.

[@jonathanratliff4780]

Perfect!!

[@williammcmurdy5359]

Thanks Peter great information as always.

[@Juan67_Az]

I just replaced the belt on my 95 tacoma at 210k miles it might have been the original one, but I'm not sure. Truck runs great tho.

[@juanjmolina]

I have a 2002 Tacoma ext cab with the 5VZ 4WD 106k miles, original belt still and will definitely consider doing this service VERY VERY soon! aside water pump and belts what else can be updated or refreshed.. I will also be throwing in the fan clutch and belts. Peter thanks for sharing this knowledge with the YT audience.

[@tikitavi7120]

Check the bearing on the fan bracket. They usually are reusable but mine was bad at the first timing belt change at 90 thousand and needed to be replaced.

[@efil4kizum]

@@tikitavi7120 what fan bracket replacement did you go with? i checked with the Yota dealer but that is not a separate item it appears, you must also get the viscous fan fluid coupler iirc

[@tikitavi7120]

@@efil4kizum I got mine on Amazon I think, without that whole assembly dealer crap.It's genuine Aisin, and don't cheap out on anything with a bearing or belt involved, get the best you can find.

[@Macerat0r]

This is why i prefer to buy engines with timing chains.. My 2004 2.4 should be good till 150k.. at 40k now.. Love your videos!

[@tylermartelle7041]

Change your oil every 3500 miles and you will never need to replace that chain.

[@jeradmiles1956]

Fair enough, but many timing chain engines tend to develop timing cover leaks, and those can take 2-3x as much labor to fix when compared to the labor to replace a timing belt.

[@tylermartelle7041]

@@jeradmiles1956 I think that relies more on the brand then anything. 7 timing chain engines in my family 4 over 350k and no leaks, no rattle, no issues.

[@jeradmiles1956]

@@tylermartelle7041 I think you've gotten very lucky then. The 5th Gen 4runner with the 1GR is notorious for this leak. My mom's 4runner has it and the Toyota book time is 21 hours of labor ($4k) to fix. I can buy 8 OEM timing belt kits for my '03 Tacoma for that price

[@neilfrasersmith]

Great video.

[@The_Madd_Golfer]

Good "timing" (no pun intended 😆) that you saw the timing belt in that condition. I had a Lexus LS400 years ago and the timing belt broke as I was driving down the freeway, literally taking it to the dealership for service just as the odometer turned 76,000 miles. Good thing that Toyota uses a non-interference engine (unlike Honda), so the engine just died (rather than breaking). I had it towed to the dealership and had it serviced under warranty!

[@McCoyMcMillan]

Excellent video!

[@sonofliberty92]

Just did the belt on my 95 T100 3.4 at 174k Idk if it was done before.

[@RockyMtnguy01]

I agree Peter that belt is NOT a mitsuboshi (OEM) belt. That belt is awful for 8 years and 100k. I have seen many 150-175k OEM belts that look way better than that belt. Crazy it didnt snap already.

[@hokie9910]

Totally agreed! Exactly what I was thinking, or it was never changed when it was said it was…

[@DaBinChe]

If original 10years is fine, but aftermarket 5years.

[@aliendroneservices6621]

Aftermarket: *_zero years,_* for me. Any aftermarket parts on any vehicle should be changed immediately for oem.

[@neverstoplearning382]

That is a non interference engine. If belt breaks nothing happens. Great engine design.

[@JesusChrist-vi2jw]

@@retired75th52I’m pretty sure this is the v6 which is the 5VZ-FE. This engine is a non interference engine, and uses a rubber belt. I believe the interference engine you are referring to is the I4 model for that same year, which uses a chain instead.

[@JesusChrist-vi2jw]

@@retired75th52oops I made a mistake, the i4 is not an interference engine either. Toyota hasn’t manufactured an interference engine in quite some time. So both v6 and i4 engines for the 2000 Tacoma are non interference.

the belt may not develop cracks for a very long period (unless you are in the desert climate) but i have read about it possibly stretching and jumping tooth? is there any truth to this?

[@janpur1417]

OEM IS MITSUBOSHI BELT WITH TOYOTA PRINTED ON IT. OEM LASTS 15 YEARS OR 150K MILES BUT BETTER TO REPLACE AT 100K MILES. I USUALLY DO 15 YEARS OR 150 K MILES IN ALL MY TOY'S. AVOID GATES AND ALL OTHER AFTERMARKET BELTS. I INSTALLED A GATES BELT AND AT 50K I NOTICED CRACKS AND HAD TO REPLACE IT.

[@sergiodjf]

Timing belt maintenace is not very forvinging! In the best case scenario your car would just stall but it could damage the engine in some cases. Pay it now or pay it later at a much higher price.

A water pump driven by the timing belt is not a good idea.

Any belts at all on an engine are a bad idea, which is why I bought a Prius c. No belts. Power brakes are electric. Power steering is electric. Water pumps (both of them) are electric. Fuel pump is electric. AC compressor is electric. I believe the oil pump is driven by a chain.
