I think this shows that it IS possible to design an engine with all the modern geegaws (cooled EGR, DI, electric WP, etc.) and not be overly complicated and hard to service like so many engines we see here.
Hate to burst your bubble, but everything you mentioned as “modern” has been around for the last 30 years and common for at least the past 20. But I get your point. Certain manufacturers, especially one that Eric is a huge fan of, intentionally complicate their designs to dissuade their owners and 3rd party auto repair shops from fixing them. There is zero reason from a financial perspective for an auto maker to build their cars to be easy to service, especially auto makers who have incredibly gullible customers who don’t care how expensive or unreliable they are, they just want the badge so they can brag to their neighbors and the other members at the country club.
I bought a NEW water pump for my old Saab, years ago now, as a prophylactic measure, because when they failed, they put the fan straight through the radiator. But it didn’t work out as planned. The NEW water pump failed, immediately, destroying the fan and the radiator! Was I pleased? You bet…
@@marc-oliviercabot3380with labor, an A25A water pump replacement is under $800. They are prone to failure. Eric throwing it in the garbage would have been the right thing to do.
@@jeremysmith1777Is that for the Toyota part, in a Toyota dealer? And why do they use an electric water pump? Sounds like one of those stupid things Audi does.
I just did an oil change on one of these for a long time costumer. 198k miles. 5k mile oil changes. Drained oil and looked like it had 1k miles on it. Ow16 oil. Clean and clear. His on board mpg said 42.5 mpg. He has without fail changed his oil every 5k miles with 0w16 oil. No timing cover leaks. No other issues with the engine. Both rear wheel bearings have been replaced.
That’s 40 oil changes at $100 (typical dealer cost) for $4000 total. That could be a lot to pay to say your engine is like new when the rest of the car is losing value - which is mostly out of your control. You didn’t say the year or usage. Might be the appropriate thing for this owner, might not.
@@donniev8181yes, it’s that cheap for some people, myself included. Not everyone is in that situation, including the owner in the post who pays for someone else to do it.
loose the toyta "oil". 5 qts of whatever brand on sale (usually Walmart supertech that is around 19.00 oem filter FROM the dealer for $3-$5 and you got sub $30 oil change. Biggest factor is knowing it's done right. I do my Tacoma every 5-6k this way. Don't let the brand trick you, yea some have minor additive packages benefits but all oil must meet API standards and Walmart/costco etc all neet the best API rating for a DI car (ILSAC-GF6B or A.) if whatever brand has that rating your good to go. Dump at 5k and put fresh whatever in it (do use OEM or a high end aftermarket filter like wix XP., fram ultra synthetic etc. Tech tip, shop around at dealers to find really cheap oem filters. I ordered 10 filters for my Tacoma (the annoying media and oring nonsense) for $3.25 a piece. No box store or even online can match that price
I am a Toyota tech in Canada. I have been with Toyota since 2018 when these A25A series engines were first being rolled out. In 6 years I have only seen one of these engines being torn down for warranty repairs, and I was that tech who repaired that engine. I had a worn out rod bearing on cylinder 4 if my memory is correct. That is really the ONLY major engine fault I have seen on the A25A engine at the dealership I work at. I have yet to see any cooling system related failures on these engines.
I worked for Toyota Australia. We replaced a couple of these under warranty. Sent them back to base or factory for inspection. Initally it was ring issue. The part numbers changed.
@@TeezerDriz Top Compression ring. Also, the gapping in the manual was also in a bulletin. We only had around 2 rebuilds per year. The engine shop was pretty much empty because we had access to long blocks.
We changed one of those on warranty not long ago. Broken top ring (cylinder 2 or 3, don't remember) but apart from that.. it seems like a pretty solid engine and so is it's 2.0l cousin, the M20A-FKS (FXS).
Those bearings end the "0w16 oil is too thin" argument. I've heard engine builders say these motors have low tension piston rings that can lead to scuffing the cylinders and oil burning issues. With Toyota building millions of these A25A engines every year, it's not unusual to see a few "bad" ones. Cheers Eric! Great channel!!
Absolutely. However, I would never use it on an engine that wasn’t designed for it! In most cases, manufacturers spec is correct, but the exceptions can save the engine!
@@I_Do_CarsI looked in other comments, but is there any way to test Toyota electric water pumps? I remember you also held onto the Prius electric water pump in a previous video.
@@duffman247in theory you could provide the pump power, ground and the PWM signal it is looking for to operate. I don't know if that's worth it. Might be interesting.
0w16 is too thin…for an engine that calls for 5w30. In the same way, 5w30 is way too thick for an engine that calls for 0w16 and would probably kill it quickly. Engines that call for thin oil typically use much tighter bearing and other clearances, along with wider bearing surfaces and different oil pumps designed for the thinner oil. TLDR, use the oil that is specified for your engine and it will be just fine. The engineers who built the engine are way more qualified to make that decision than you.
The twin turbo 6s are under warranty, and Toyota will never let a bad engine replaced under warranty loose for people to analyze. Neither will any other manufacturer.
@@bigdaddymak1439 except its not caused by debris. Oil starvation causes bearing failures that creates the debris. Any engine builder will tell you if debris is in the eng it will blow up within the first or second oil change. Not 40,000 miles later.
@@fl_atv_riders4455 you're wrong it's only one bearing that gets starved. It just takes a while for it to get dislodged and clog the gallery to the bearing. Hyundai Kia has had the same issue.
@@bigdaddymak1439 In fact. My SiL's KIA goes in soon to have the engine assessed under the extended warranty. The oil cap floats when you loosen it well running.

Please don't stop releasing the videos on a Saturday night. It's morning in the UK and I don't get out bed until I've watched the latest tear down. Thanks for the great videos Eric, always fascinating and entertaining.
I asked for an A25A video so thanks for doing one finally! They seem like a really well designed engine. A guy did 470k miles on his Rav4 hybrid so I don't doubt the longevity of the engine if taken care of.
Thank you Eric for tearing one of these down, ive not seen a single video about these engines! I just purchased a 2024 Camry SE and the car is a dream to drive. These engines have great heat efficiency, I can turn the car off and come back 4 hours later and the engine will still be warm. Change your antifreeze every 2 years people, it starts to get acidic after 30k miles.
@@donniev8181 The car care nut channel has a rebuild video for the A25A from when he worked at Toyota. A piston exploded causing a short block replacement.
@FrankySilverFace I don't think that was that was the A25A-FXS 0 engine, I believe that was the older 4cyl out of a 09' Camry, but I could be mistaken. What is the specific title of the video.
As always Eric, thanks for the Saturday night entertainment. Nice to see Mrs. IDoCars make a cameo in the video as well. I only wonder what's she going to do with 2 used timing chain guides? :D
Toyota quietly replaced tens of thousand of those engines because of bad castings. Water and/or oil was seeping through the blocks. If it was oil, the engine was replaced. If it was water they snuck in block sealer. My 2020 Camry smelled like hot antifreeze during the summer. It was by accident I noticed block sealer was added to mine when I picked it up from the dealer for the third time because of continuous problems Toyota said were normal. Toyota didn't do a recall, they left it up to the customer to find the problem. More are getting out of warranty now, it might get interesting.
I have a 2016 Camry. I change the oil every 3k miles. I use mobile one ep oil and not the cheap stuff. I use a new Toyota oil filter each time too. I change the coolant and trans fluid every 30k. It may be overkill, but I don’t care. It has 100k and drives like it has 100 miles.
Ok so I work on a fleet of taxi cabs we have all hybrid Camrys. Years range from 2014-2019. Our 2019’s are the most problematic at around 250 k I put a new cylinder head on them with all new gaskets and kick them out the door. Our 2014-2016 we on average get 500-750k on these cars pretty amazing. Definitely not a fan of the newer A25A engine. Lots of issues. Great video
I have a Corolla with the 2ZR-FE engine (2019, the last year before Dynamic force engine switchover) I get less MPG (like 30 instead of 38 to 40) but no EGR... seems like my engine will last longer than the new ones.
Agreed, the intake side head bolts seemed to be, by all assumptions, correct torque, but the exhaust side all seems, a little... "less tight" based off the sound. Plus, when he flipped the headgasket, you could see how clean the steel was on the waterport lines, vs cylinder 4, that wasn't as clean. I think someone over heated it, and it lifted that side very badly, then became a slight coolant burner... which eventually got into a milkshake maker. And maybe the engines are so cheap from wrecked cars that, "cheaper to change it, than do a head gasket." happened.
Speculations aside on how these fail, as someone with a RX350 with a 237k mile 2GR-FE, I’m just happy to see a tear down of any Toyota engine to see what’s behind the scenes
Used to be a toyota tech. I replaced one of these short blocks due to the electric water pump failure and customers continue to drive. The electric water pump is suspect for me here.
If electric water pump fail it will trigger immediately a dashboard warning lights so if that’s the case then it’s a drivers error for continuing driving with fault
I bought a '20 Camary used and the service records were good. I will do my best to keep up with the maintenance. Oil change every 5k or sooner. After reading the comments i now know i need to watch out for water pump failure. Dig this channel!
I am currently a Toyota tech. Seen the water pumps go out and cause the coolant and engine oil to overheat. They will damage the engine and coolant system if not fixed.
I work for the Toyota supplier that makes the exhaust manifold for that engine... this engine is used on all sorts of vehicles (very high volume)... like Frank's Red Hot, they put that "stuff" on everything! Said manifold is a complicated one... 4 runners and an EGR pipe with a cat on the end. Hence why you didn't get one with it. One of the trickier ones to produce due to all the pipes and welds needed to make it.
My wife's 2020 Rav4 has this engine, and I am *ruthless* on the 6mo/5,000 mile oil change interval. I saw this video come up and kinda gasped, then felt good to see this didn't look like some chronic issue. Great as always.

The (darkly) funny thing about Scotty is thag when he eventually does die there won't be a video with him telling us that. Thanks as always Eric, compulsory viewing - in tribute to you I now carefully remove clamps before cutting hoses off, and send water pumps to the moon when I change them. +1 for the idea of merch too, I'd wear it!
These are my favourite videos. I've seen endless components that have exploded, it's not very common to see ones that have failed, but not catastrophically. It gives us a chance to see the subtle wear and tear.
Would you consider making a video showing how to remove difficult connectors, i.e. electrical, HVAC lines, transmission lines, etc with close-ups and the special tools needed?
That engine shows signs of burning oil. The ring lands for one of those look terrible. Engines with low-tention piston rings will gum up the ring lands, score the cylinder walls and start to comsuem oil if you don't change the oil regularly. At 5000 mi not 7500 to 10,000. Oil is the key!! Keep it clean and use good oil and these engines will go 300K. This one was not well maintained. Love your videos! Thanks for sharing all the information too.
Eric, thank you for including chapters on this video. I do well with 15-20 minute video, but with longer ones like this I lose interest. Following along with the chapters makes it so much better. For me at least.
The rumblings I’ve heard are these engines are vulnerable to “cylinder wash down” when the engine isn’t aloud to reach operating temperature. ie just moving the vehicle out of the driveway then shutting it off after only a minute or two. A few years of this procedure and this is what happens.
I must be doing something right . . . I have two different log ins and I think I've only gotten a few at work where I'm not signed into YT. That said, what is recommended there is garbage.
These are great engines. I bought a 2020 rav4 hybrid new and had it for 2.5 years and 46k kms. Stick to 8k km oil changes, no matter what the manufacturer says. They’ll last forever if you stick to that and use good oil.
There are few hard truth's in life but one of them is (speaking cars here, not trucks) get yourself a Honda or Toyota vehicle with a 2.0-2.5l naturally aspirated 4 cylinder, keep it maintained and don't drive it like an idiot and you won't wear it out.
According to AMD on The Car Care Nut, those cylinders have what is essentially a spray-on coating that makes those blocks non-serviceable and pretty much a one time use.
I was thinking the same thing. Every cylinder had multiple dark vertical streaks. According to the car the car care nut, that block is done. I believe it was a 2AR 4 cylinder oil burning engine the car car nut was looking at in that episode. But he was adamant that when you see the dark, verticle streaking, even in just 1 cylinder, it's time for a new engine.
Early Dynamic Force engines had head gasket issues. Higher compression (more heat/pressure for efficiency) + new engine = some issues. Dynamic Force engines are greats engines and this was probably an issues from day one. Defective engine and only showed its face around 100K miles unfortunately Don’t think it’s worth worrying about it just yet. I had seen a couple fail this way already though 2.0L and 2.5L Dynamic Force engines. Toyota is using a very similar technology to Mazda and they also faced some head gasket issues but also a non issues tbh. Super rare but very unfortunate if you do have it. This is just the issue with modern engines. Thinner everything and smaller with more pressure and temperature than ever. Plus making a lot more power than before.
I don't know but on this Toyota Engines you only see quality and perfection all very well engineered and NO built in planned obsolescence like other manufacturers, that is why Toyota is the best!
I’ve made this comment throughout the channel already but please do a 2.4 2AZ. They’re blown up everywhere from bad piston rings and oil starvation, some are also known for head gasket issues. Wanna see you tear one down.
I have a 2019 camry with this engine my guess would be the water pump gave up which lead to an over heat. I am thinking if you check those heads they will be slightly warped. I am apart of the 8th gen camry FB group and water pump failure is pretty common. The consensus seems to be to just buy a water pump and have it on hand and replace every 80-90k as preventative maintenance. There are ride share members who have 200k+ in the group so they can for sure go the distance.
I tore down one of these too. It got so hot the pistons melted to the cylinder wall. It was pretty unbelievable to see the damage inside of it. The bearings were perfect on the inside. If you want I have a lot of the engine still I would gladly donate if you cover the shipping lol
A lot of people mentioned that the water pump is usually a common failure for these engines around that mileage. The one I tore down died because of that sadly
Based on the evidence it ran low on coolant and got hot, overheating the engine. There was the corrosion internally where coolant should have been, the steam cleaned piston, and the brittle conduit pieces all over the engine which only happens from heat.
Thank you for what you do and sharing it with the rest of us. I enjoy both the engine tear downs and the car rescues. I am hoping one day you to tear down a BMW M54 engine. I have a 2002 E46 330i with 278K miles that keeps on running. Thank you again.
Here's a suggestion for a future water pump removal scene...Eric removes all the bolts except for one. His female "assistant" pushes Eric out of way, removes the last bolt and runs the pump to the discard box with a slam dunk, saying, "gotcha!"
those water pumps are pretty expensive. one of my friends has a 2019 and the water pump went bad at 75,XXX miles. the electric water pump was around $290..
Glad to see this teardown . My 2022 Venza Hybrid has the A25A-FXS . Think pretty much the same . I live in Phoenix, always hot here and did worry about the use of 0-16 oil. Had the car 3 years now with 34,000 miles . No issues yet 🤞🏼
0W-16 is a USA EPA compliance matter. No EPA in Mexico so Camry manuals in Mexico tell owners they can use 0W-16, 0W-20, 5W-20, and 5W-30 in the A25A engine. 10W-30 if winter temps do not get below zero degrees F.`
Engine overheated and caused a leaking head gasket and thats why it has one clean piston and one sparkplug the electrode was clean and wet looking ! You can bake new coatings on the piston skirts in your home oven and reuse them or buy new pistons if you end up boring the sleeves and put this engine back together.
@@theredscourge - Its not powder coating paint, it is liquid ceramics and it depends on the brand, some say not to use it in an oven you cook food in due to the chemicals in the ceramic liquid, other brands say theirs is ok.
As someone else said (and maybe more than one someone's) I would love to see a straightedge on the head and the block deck. I suspect the coolant went low (yes, I am looking at you, EGR cooler) and the engine got a bit toasty, leading to warpage. But, yes, it was caught early before anything catastrophic. I might dingle-ball those cylinders, surface what needs to be surfaced, replace the rings, and send it! Oh, and re-use those fantastic rod and main bearings as well. What the F is that coating? I need that in ALL my engines! Thanks, Eric, for the infotainment.
You've gotta be careful wearing basket ball shorts and swinging around those cheater bars. One of these times your going to judge the bar wrong and RING THAT BELL!
When I bought my most recent Toyota,a 2020 Corolla LE,I chose it because it was the last year you could get the tried and proven,for over thirty years 1.8 litre engine.I feel I made the right choice.I felt the new Dynamic Force engines were too new and had too many potential failure points.I also don't like that Toyota went back to an EGR valve on these motors,a potential headache of clogging up and needing cleaned.
We have a 2023 Corolla with the old 1.8, the 2024 we just got has the new 2.0. I personally can't feel much difference in power and I can't imagine the fuel economy is much better either. Only time will tell the reliability. All I do know is properly maintained that old 1.8 will go forever.
Im assuming you know but those 1.8s over those 30 years were multiple completely different engines, Toyota just has a formula that they follow and it works
Same, I have a 2019 corolla... it was mostly 2020 when they switched from the 1.8 2zr-fe to the m20a dynamic force.. mile per gallon went way up... about 20% higher... but i dont care. I still get 30mpg and I know its much more reliable. Taken care of these are 500k miles engines instead of 250k mile engines like the new ones (loosely speaking, there are exceptions)
Hey Eric, I have replaced two intakes on a 23 and a 24 corolla with the M20A-FKS which is the same basic engine in 2.0 displacement. These intakes were replaced because of crashes - not mech failure; however I did notice there was white powder in the plastic egr feed pipe on the front, and I though it odd. Not a lot of powder, but some. These cars only had 12k and 8k miles respectively, but I think it's something to put in the back of your mind if you have one of these cars - to check the coolant levels periodically.
Q: 2001 Subaru Outback LL Bean. It has always over the 13 years I've owned it had an issue where slowly uses coolant, a few pints per year. Normally this car sees about 2000 miles per year driving to and from the airport in Fort Lauderdale, since it is an "airport car", I fly for a tiny cargo airline in Memphis that paints the tails of the planes purple. Anyway, there are no leaks. This is a six cylinder engine, these don't have head gasket issues at all. Nothing in the oil, but the coolant overflow reservoir rises on long drives. I recently drove it 1050 miles from Fort Lauderdale to Memphis, and it pushed about 1/2 gallon of coolant into the coolant reservoir at a constant 70 mph with the AC cranking in 97 degree heat, I knew this because there was coolant spray on top of the engine from the overflow reservoir. The radiator cap is new, straight from Subaru and was made in Japan. The temperature gauge stayed right in the middle, where it always sits. Hmm.... Thoughts?
Speaking of never able to find engine teardowns of engines, the K20C2 from the new civics is a wasteland in terms of teardowns, would love to see one on your channel!
-The engine in this video? I bet the owner lived next to the interstate highway. He went to work and got into the powerband when the engine was COLD. And while he may not have floored it, he did it day after day after day after day.....And it caught up to him. You cannot do this to an ICE engine! For the first two minutes/two miles you have to drive the car gently. You know, the way you normally drive it, no more than half throttle, no more than 3000 rpm. I drive a Porsche Cayman S and I have the screen set up to show me oil temperature, water temperature, oil pressure and voltage and BOTH the oil temperature and coolant temperature gauges have a blue line, and that blue line means what I have said....No more than half throttle and no more than 3000 RPM. I think the C8 Corvette has this as well, but this is true of EVERY car! For two miles or two minutes DO NOT got to full throttle or rev the engine out! Yes, you can do this in an emergency, but if you do it regularly you are going to be replacing the engine.
My idiot friend used to floor his 335i cold. I kept yelling at him not to do that. "F it, it's leased." Another reason to avoid lease returns... and used rentals. The above is basic, sound advice that I have followed since Mr Auto Shop's class in high school. Once he explained why it made total sense.
Today, I don’t view Toyota as any more reliable than any other reputable brand. Cost engineering is omnipresent everywhere, it is simply a reality of how business develops-an inevitability. We know exactly how to make simple, efficient, resilient engines that last a million miles with exceptions for severely poor maintenance, but that simply isn’t profitable, and ultimately, buyers seem to be fine with this… At least, fine and/or un/misinformed enough to provide the capitol to incentivize these business practices. So, delicate, complex, poorly serviceable/repairable engines with an inherently finite component lifespan (plastics everywhere) will not be looked back upon fondly, but it’s what we get. And sooner rather than later, we WON’T get replacement parts, even via aftermarket. There’s just too much, and moving customers to a new (increasingly disposable/predatory) product is where it’s at… Ever hear the “boiling frog” analogy?
@@Alltakenbla The concept of minimum viable product applied in its truest form. What are we going to do, produce cars in our garages? In all fields, we are slowly becoming a captive market, even with all the “competition”… After all, companies within the same field abide by the same market forces and are subject to the same financial incentives, so they will naturally implement many of the same techniques to bump profits. Because remember, it isn’t just about being profitable, it’s about being INCREASINGLY profitable each quarter.
Yes, BUT. Don't forget that external factors play a huge role in this as well. Unrealistic fuel economy mandates have caused manufacturers to undertake brutal weight-reduction programs, and things that should be metal are now plastic - or worse, missing altogether (like spare tires). Not to mention forcing the use of unproven and unreliable technologies which drive the cost of new cars through the roof while only providing minuscule increases in mileage. All this to supposedly 'reverse' a meteorological phenomenon whose effects have clearly been exaggerated. The people you vote for are responsible for this mess as well.
I was thinking when you were struggling with the head bolts that I suspected the engine had been hot at some point, especially on the "lower" side which you really had to force on. The proof is cylinder 2, clearly (pun intended) washed by coolant. The amount of wear in the cylinders was pretty odd too, makes me think that it was run kind of hot for a while, perhaps without the owner realizing it was slowly chewing through the cooling juice. I would guess that it was a smoker so it was an easy and obvious replacement case.
My grandmother had a 97 Toyota camry. It never failed, it was forced off the road when my drunk uncle ran it into a ditch. 300k + miles and still started up first try.
Topical video is topical; I've got a 2024 Camry as a rental while my car is at the body shop (beware Subarus driven by kids). Thing makes okay power for what it is and is surprisingly eager to wind out when floored. Only getting 28-30 mpg though but that might be because I sometimes drive like Ayrton Senna.
Had a 2025 (!!!) Camry Hybrid rental last week and damn that thing would (briefly) light up the fronts when pressured. Which was often. I would never buy a used rental car based on the way I drive them. 90mph in reverse running late to the airport, every warning light blazing, "Yeah it's fine sure I filled it up no prob gotta jet."
I built the top end of that thing. 😂 well, at least the camshaft housing. (Not tower)Those cam cap bolts are pre threaded by hand before being torqued by a machine. It hurt just watching you unbolt them. 😢
Wow, wasn’t sure if I’d see a late Camry engine on your channel any time soon lol. I haven’t seen, or maybe you have tore down but I would have to look, 2.2 twin cam out of old GM compact sedans, late 90’s ford rangers engines, the GM 3.4 v6, I’m sure there are more, immortal engines out there, but I love watching your tear downs and especially the reliable engines.
One medical transport driver last checked in with 501,950 miles on his A25A Camry. He changes oil every 4,000 miles and uses 0W-20 Mobil 1. I use 5W-30 in mine because outside of the USA, Camry manuals say 5W-30 can be used full time, even 10W-30 in the summer.
116k miles is barely broken in for Toyota engines. Such a shame that this one suffered a premature death. That's how much mileage my 2013 Camry 2.5L had when I traded it in for a new ride 4 years ago...the engine still ran like new with nothing done to it except oil changes

I am a Toyota tech in Canada. I have been with Toyota since 2018 when these A25A series engines were first being rolled out. In 6 years I have only seen one of these engines being torn down for warranty repairs, and I was that tech who repaired that engine. I had a worn out rod bearing on cylinder 4 if my memory is correct. That is really the ONLY major engine fault I have seen on the A25A engine at the dealership I work at. I have yet to see any cooling system related failures on these engines.
I worked for Toyota Australia. We replaced a couple of these under warranty. Sent them back to base or factory for inspection. Initally it was ring issue. The part numbers changed.
@@royferntorp low tension rings? New part number a higher tension ring?
What do you think caused this one to fail - overheating?
@@TeezerDriz Top Compression ring. Also, the gapping in the manual was also in a bulletin. We only had around 2 rebuilds per year. The engine shop was pretty much empty because we had access to long blocks.
We changed one of those on warranty not long ago. Broken top ring (cylinder 2 or 3, don't remember) but apart from that.. it seems like a pretty solid engine and so is it's 2.0l cousin, the M20A-FKS (FXS).
Those bearings end the "0w16 oil is too thin" argument. I've heard engine builders say these motors have low tension piston rings that can lead to scuffing the cylinders and oil burning issues. With Toyota building millions of these A25A engines every year, it's not unusual to see a few "bad" ones. Cheers Eric! Great channel!!
Absolutely.
However, I would never use it on an engine that wasn’t designed for it!
In most cases, manufacturers spec is correct, but the exceptions can save the engine!
Toyotas are well engineered for thin oil. Hyundai/Kia not so much 😂
@@I_Do_CarsI looked in other comments, but is there any way to test Toyota electric water pumps? I remember you also held onto the Prius electric water pump in a previous video.
@@duffman247in theory you could provide the pump power, ground and the PWM signal it is looking for to operate. I don't know if that's worth it. Might be interesting.
0w16 is too thin…for an engine that calls for 5w30. In the same way, 5w30 is way too thick for an engine that calls for 0w16 and would probably kill it quickly. Engines that call for thin oil typically use much tighter bearing and other clearances, along with wider bearing surfaces and different oil pumps designed for the thinner oil. TLDR, use the oil that is specified for your engine and it will be just fine. The engineers who built the engine are way more qualified to make that decision than you.
The twin turbo 6s are under warranty, and Toyota will never let a bad engine replaced under warranty loose for people to analyze. Neither will any other manufacturer.
Multiple videos on UA-cam of that engine tore down. Toyota already said it's from debris in the oil gallery
there's a lot of crashed vehicles he could recover from.
@@bigdaddymak1439 except its not caused by debris. Oil starvation causes bearing failures that creates the debris. Any engine builder will tell you if debris is in the eng it will blow up within the first or second oil change. Not 40,000 miles later.
@@fl_atv_riders4455 you're wrong it's only one bearing that gets starved. It just takes a while for it to get dislodged and clog the gallery to the bearing. Hyundai Kia has had the same issue.
@@bigdaddymak1439 In fact. My SiL's KIA goes in soon to have the engine assessed under the extended warranty. The oil cap floats when you loosen it well running.

@@sammyjammy6647 Yes it was running fine, the dealer had it for sale for like $17k lol. 46 oil changes

These engines have great heat efficiency, I can turn the car off and come back 4 hours later and the engine will still be warm.

Toyota quietly replaced tens of thousand of those engines because of bad castings. Water and/or oil was seeping through the blocks. If it was oil, the engine was replaced. If it was water they snuck in block sealer. My 2020 Camry smelled like hot antifreeze during the summer. It was by accident I noticed block sealer was added to mine when I picked it up from the dealer for the third time because of continuous problems Toyota said were normal. Toyota didn't do a recall, they left it up to the customer to find the problem. More are getting out of warranty now, it might get interesting.
I have a 2016 Camry. I change the oil every 3k miles. I use mobile one ep oil and not the cheap stuff. I use a new Toyota oil filter each time too. I change the coolant and trans fluid every 30k. It may be overkill, but I don’t care. It has 100k and drives like it has 100 miles.
Every single vehicle that has really high miles didn’t get there with neglected maintenance. Don’t ever apologize for that! 👍
Ok so I work on a fleet of taxi cabs we have all hybrid Camrys. Years range from 2014-2019. Our 2019’s are the most problematic at around 250 k I put a new cylinder head on them with all new gaskets and kick them out the door. Our 2014-2016 we on average get 500-750k on these cars pretty amazing. Definitely not a fan of the newer A25A engine. Lots of issues. Great video
What kind of issue do you see with them when they get high in the miles?
Please tell us what wears out at around 250K that requires cylinder head replacement?
I have a Corolla with the 2ZR-FE engine (2019, the last year before Dynamic force engine switchover) I get less MPG (like 30 instead of 38 to 40) but no EGR... seems like my engine will last longer than the new ones.
I never miss a teardown, my Saturday night ritual.
No uncle Rodney today though 😂😂😂
Glad to see Toyota still making engines that are somewhat straightforward to take apart.
It would been interesting to see if the head had gotten warped, by putting a straight edge against the surface of the head.
Agreed, the intake side head bolts seemed to be, by all assumptions, correct torque, but the exhaust side all seems, a little... "less tight" based off the sound.
Plus, when he flipped the headgasket, you could see how clean the steel was on the waterport lines, vs cylinder 4, that wasn't as clean.
I think someone over heated it, and it lifted that side very badly, then became a slight coolant burner... which eventually got into a milkshake maker. And maybe the engines are so cheap from wrecked cars that, "cheaper to change it, than do a head gasket." happened.
@@th3R0b0t - I just was surprised that someone would come to that conclusion with a Toyota engine! Hyundai maybe, but not a Toyota...

Ive noticed they sure like layers in modern engines. Upper cam thingy, lower cam thingy, inner and out tim8ng covers. upper and lower oil pans.
I bought a '20 Camary used and the service records were good. I will do my best to keep up with the maintenance. Oil change every 5k or sooner. After reading the comments i now know i need to watch out for water pump failure. Dig this channel!
My 2021 RAV4 is sitting at 73k miles. I will consider having the water pump replaced soon just so it doesn’t fail in the future.
I am currently a Toyota tech. Seen the water pumps go out and cause the coolant and engine oil to overheat. They will damage the engine and coolant system if not fixed.
I work for the Toyota supplier that makes the exhaust manifold for that engine... this engine is used on all sorts of vehicles (very high volume)... like Frank's Red Hot, they put that "stuff" on everything!
Said manifold is a complicated one... 4 runners and an EGR pipe with a cat on the end. Hence why you didn't get one with it. One of the trickier ones to produce due to all the pipes and welds needed to make it.

These are my favourite videos. I've seen endless components that have exploded, it's not very common to see ones that have failed, but not catastrophically. It gives us a chance to see the subtle wear and tear.
"None of the plugs wre regapped by the pistons" awesome quote!!
On these engines, Toyota recommends that LOF change is 10k, I change my oil at 5k, and filter at 10k.
Would you consider making a video showing how to remove difficult connectors, i.e. electrical, HVAC lines, transmission lines, etc with close-ups and the special tools needed?
That engine shows signs of burning oil. The ring lands for one of those look terrible. Engines with low-tention piston rings will gum up the ring lands, score the cylinder walls and start to comsuem oil if you don't change the oil regularly. At 5000 mi not 7500 to 10,000. Oil is the key!! Keep it clean and use good oil and these engines will go 300K.
This one was not well maintained.
Love your videos! Thanks for sharing all the information too.
Eric, thank you for including chapters on this video. I do well with 15-20 minute video, but with longer ones like this I lose interest. Following along with the chapters makes it so much better. For me at least.
The rumblings I’ve heard are these engines are vulnerable to “cylinder wash down” when the engine isn’t aloud to reach operating temperature. ie just moving the vehicle out of the driveway then shutting it off after only a minute or two. A few years of this procedure and this is what happens.
I caught the click bait reference too. I checked the "not interested " in his channel and now I don't even get him as a suggestion!

Great channel thank you for taking the time to record and share
There are few hard truth's in life but one of them is (speaking cars here, not trucks) get yourself a Honda or Toyota vehicle with a 2.0-2.5l naturally aspirated 4 cylinder, keep it maintained and don't drive it like an idiot and you won't wear it out.
I Do Cars, your dedication is paying off, keep it up
As someone with 60k on my 19 Camry 2.5, this teardown makes me incredibly happy with how well built this motor is.
According to AMD on The Car Care Nut, those cylinders have what is essentially a spray-on coating that makes those blocks non-serviceable and pretty much a one time use.
I was thinking the same thing. Every cylinder had multiple dark vertical streaks. According to the car the car care nut, that block is done. I believe it was a 2AR 4 cylinder oil burning engine the car car nut was looking at in that episode. But he was adamant that when you see the dark, verticle streaking, even in just 1 cylinder, it's time for a new engine.
Please get your hands on a 2016-2018 6.4 Hemi 392. Would love to see that one time
“Clickbait champion that dies 15 times a year.”
That had me dead.
Early Dynamic Force engines had head gasket issues. Higher compression (more heat/pressure for efficiency) + new engine = some issues.
Dynamic Force engines are greats engines and this was probably an issues from day one.
Defective engine and only showed its face around 100K miles unfortunately
Don’t think it’s worth worrying about it just yet. I had seen a couple fail this way already though
2.0L and 2.5L Dynamic Force engines.
Toyota is using a very similar technology to Mazda and they also faced some head gasket issues but also a non issues tbh. Super rare but very unfortunate if you do have it.
This is just the issue with modern engines. Thinner everything and smaller with more pressure and temperature than ever. Plus making a lot more power than before.
You forgot Sea Foam! I'm always cleaning with Sea Foam! 😂
I don't know but on this Toyota Engines you only see quality and perfection all very well engineered and NO built in planned obsolescence like other manufacturers, that is why Toyota is the best!
The Car Care Nut enters the chat....
I busted a car care nut once
…and that’s okay.
I would like to see the day that a current-day engine (with care) will routinely go "forever." Very few, for sure.
I’ve made this comment throughout the channel already but please do a 2.4 2AZ. They’re blown up everywhere from bad piston rings and oil starvation, some are also known for head gasket issues. Wanna see you tear one down.
I have a 2019 camry with this engine my guess would be the water pump gave up which lead to an over heat. I am thinking if you check those heads they will be slightly warped. I am apart of the 8th gen camry FB group and water pump failure is pretty common. The consensus seems to be to just buy a water pump and have it on hand and replace every 80-90k as preventative maintenance. There are ride share members who have 200k+ in the group so they can for sure go the distance.
I tore down one of these too. It got so hot the pistons melted to the cylinder wall. It was pretty unbelievable to see the damage inside of it. The bearings were perfect on the inside. If you want I have a lot of the engine still I would gladly donate if you cover the shipping lol
A lot of people mentioned that the water pump is usually a common failure for these engines around that mileage. The one I tore down died because of that sadly
Based on the evidence it ran low on coolant and got hot, overheating the engine. There was the corrosion internally where coolant should have been, the steam cleaned piston, and the brittle conduit pieces all over the engine which only happens from heat.
Appreciate the tear down but can't help noticing how this is absolutely ancient technology.
That's how Toyota rolls. A25A is actually Atkinson-cycle though.
I really like your videos and your humor. been wanting to ask for a long time. Are the snack packs on the shelf for sale?
Thank you for what you do and sharing it with the rest of us. I enjoy both the engine tear downs and the car rescues. I am hoping one day you to tear down a BMW M54 engine. I have a 2002 E46 330i with 278K miles that keeps on running. Thank you again.
Here's a suggestion for a future water pump removal scene...Eric removes all the bolts except for one. His female "assistant" pushes Eric out of way, removes the last bolt and runs the pump to the discard box with a slam dunk, saying, "gotcha!"
Next time you throw a timing chain guide. You should do the swoosh sound from happy Gilmore when he hit the ball.
those water pumps are pretty expensive. one of my friends has a 2019 and the water pump went bad at 75,XXX miles. the electric water pump was around $290..
Glad to see this teardown . My 2022 Venza Hybrid has the A25A-FXS . Think pretty much the same . I live in Phoenix, always hot here and did worry about the use of 0-16 oil. Had the car 3 years now with 34,000 miles . No issues yet 🤞🏼
0W-16 is a USA EPA compliance matter. No EPA in Mexico so Camry manuals in Mexico tell owners they can use 0W-16, 0W-20, 5W-20, and 5W-30 in the A25A engine. 10W-30 if winter temps do not get below zero degrees F.`
@@4af That is very interesting information . Thank you for that . I wonder what some other countries call for ?
Engine overheated and caused a leaking head gasket and thats why it has one clean piston and one sparkplug the electrode was clean and wet looking ! You can bake new coatings on the piston skirts in your home oven and reuse them or buy new pistons if you end up boring the sleeves and put this engine back together.
I sure wouldn't recommend using the same oven for food and for powder coating, sounds like a good way to bake cancer cakes
@@theredscourge - Its not powder coating paint, it is liquid ceramics and it depends on the brand, some say not to use it in an oven you cook food in due to the chemicals in the ceramic liquid, other brands say theirs is ok.
As someone else said (and maybe more than one someone's) I would love to see a straightedge on the head and the block deck. I suspect the coolant went low (yes, I am looking at you, EGR cooler) and the engine got a bit toasty, leading to warpage. But, yes, it was caught early before anything catastrophic. I might dingle-ball those cylinders, surface what needs to be surfaced, replace the rings, and send it! Oh, and re-use those fantastic rod and main bearings as well. What the F is that coating? I need that in ALL my engines! Thanks, Eric, for the infotainment.

When I bought my most recent Toyota,a 2020 Corolla LE,I chose it because it was the last year you could get the tried and proven,for over thirty years 1.8 litre engine.I feel I made the right choice.I felt the new Dynamic Force engines were too new and had too many potential failure points.I also don't like that Toyota went back to an EGR valve on these motors,a potential headache of clogging up and needing cleaned.
We have a 2023 Corolla with the old 1.8, the 2024 we just got has the new 2.0. I personally can't feel much difference in power and I can't imagine the fuel economy is much better either. Only time will tell the reliability. All I do know is properly maintained that old 1.8 will go forever.
Im assuming you know but those 1.8s over those 30 years were multiple completely different engines, Toyota just has a formula that they follow and it works
Same, I have a 2019 corolla... it was mostly 2020 when they switched from the 1.8 2zr-fe to the m20a dynamic force.. mile per gallon went way up... about 20% higher... but i dont care. I still get 30mpg and I know its much more reliable. Taken care of these are 500k miles engines instead of 250k mile engines like the new ones (loosely speaking, there are exceptions)
Hey Eric, I have replaced two intakes on a 23 and a 24 corolla with the M20A-FKS which is the same basic engine in 2.0 displacement. These intakes were replaced because of crashes - not mech failure; however I did notice there was white powder in the plastic egr feed pipe on the front, and I though it odd. Not a lot of powder, but some. These cars only had 12k and 8k miles respectively, but I think it's something to put in the back of your mind if you have one of these cars - to check the coolant levels periodically.
To the "Wait! There's more!" Reference...
Now if I hear Car Wizard start using.... "There was Malice in the combustion palace"

With his Teslong he can actually see the malice without even tearing the engine down.
Q: 2001 Subaru Outback LL Bean. It has always over the 13 years I've owned it had an issue where slowly uses coolant, a few pints per year. Normally this car sees about 2000 miles per year driving to and from the airport in Fort Lauderdale, since it is an "airport car", I fly for a tiny cargo airline in Memphis that paints the tails of the planes purple. Anyway, there are no leaks. This is a six cylinder engine, these don't have head gasket issues at all. Nothing in the oil, but the coolant overflow reservoir rises on long drives. I recently drove it 1050 miles from Fort Lauderdale to Memphis, and it pushed about 1/2 gallon of coolant into the coolant reservoir at a constant 70 mph with the AC cranking in 97 degree heat, I knew this because there was coolant spray on top of the engine from the overflow reservoir. The radiator cap is new, straight from Subaru and was made in Japan. The temperature gauge stayed right in the middle, where it always sits. Hmm....
Thoughts?
Combustion pressure in the coolant. Do the head gasket test kit.. Sorry to hear that..

Speaking of never able to find engine teardowns of engines, the K20C2 from the new civics is a wasteland in terms of teardowns, would love to see one on your channel!
-The engine in this video? I bet the owner lived next to the interstate highway. He went to work and got into the powerband when the engine was COLD. And while he may not have floored it, he did it day after day after day after day.....And it caught up to him. You cannot do this to an ICE engine! For the first two minutes/two miles you have to drive the car gently. You know, the way you normally drive it, no more than half throttle, no more than 3000 rpm. I drive a Porsche Cayman S and I have the screen set up to show me oil temperature, water temperature, oil pressure and voltage and BOTH the oil temperature and coolant temperature gauges have a blue line, and that blue line means what I have said....No more than half throttle and no more than 3000 RPM. I think the C8 Corvette has this as well, but this is true of EVERY car! For two miles or two minutes DO NOT got to full throttle or rev the engine out! Yes, you can do this in an emergency, but if you do it regularly you are going to be replacing the engine.
I agree with you! Unfortunately 9/10 drivers will hear this, nod at you, and then drive however they want anyway.
I do this and my back seat drivers tell me to quit being a slowpoke!

We know exactly how to make simple, efficient, resilient engines that last a million miles with exceptions for severely poor maintenance, but that simply isn’t profitable, and ultimately, buyers seem to be fine with this… At least, fine and/or un/misinformed enough to provide the capitol to incentivize these business practices.
So, delicate, complex, poorly serviceable/repairable engines with an inherently finite component lifespan (plastics everywhere) will not be looked back upon fondly, but it’s what we get.
And sooner rather than later, we WON’T get replacement parts, even via aftermarket. There’s just too much, and moving customers to a new (increasingly disposable/predatory) product is where it’s at… Ever hear the “boiling frog” analogy?
Everything is moving towards "single use".
@@Alltakenbla The concept of minimum viable product applied in its truest form. What are we going to do, produce cars in our garages? In all fields, we are slowly becoming a captive market, even with all the “competition”… After all, companies within the same field abide by the same market forces and are subject to the same financial incentives, so they will naturally implement many of the same techniques to bump profits. Because remember, it isn’t just about being profitable, it’s about being INCREASINGLY profitable each quarter.
Toyotas don't last like years ago I have a 1993 Corolla with 408,000 miles you won't see a New one do that.
@@mittiejackson3427 you have new ones coming off the line with sand or metal shavings still inside them. Fantastic.
Yes, BUT. Don't forget that external factors play a huge role in this as well. Unrealistic fuel economy mandates have caused manufacturers to undertake brutal weight-reduction programs, and things that should be metal are now plastic - or worse, missing altogether (like spare tires). Not to mention forcing the use of unproven and unreliable technologies which drive the cost of new cars through the roof while only providing minuscule increases in mileage. All this to supposedly 'reverse' a meteorological phenomenon whose effects have clearly been exaggerated. The people you vote for are responsible for this mess as well.
6 days since you got a Miata, Guess you where on your vacation all week then, LOL.
cool engine ya found eric thanks for snagging it and the teardown always interesting to watch
Great video.
I enjoy all of your videos
I was thinking when you were struggling with the head bolts that I suspected the engine had been hot at some point, especially on the "lower" side which you really had to force on. The proof is cylinder 2, clearly (pun intended) washed by coolant. The amount of wear in the cylinders was pretty odd too, makes me think that it was run kind of hot for a while, perhaps without the owner realizing it was slowly chewing through the cooling juice. I would guess that it was a smoker so it was an easy and obvious replacement case.
My grandmother had a 97 Toyota camry. It never failed, it was forced off the road when my drunk uncle ran it into a ditch. 300k + miles and still started up first try.
Man! I love your sense of humor 🙂
Topical video is topical; I've got a 2024 Camry as a rental while my car is at the body shop (beware Subarus driven by kids). Thing makes okay power for what it is and is surprisingly eager to wind out when floored.
Only getting 28-30 mpg though but that might be because I sometimes drive like Ayrton Senna.
Had a 2025 (!!!) Camry Hybrid rental last week and damn that thing would (briefly) light up the fronts when pressured. Which was often. I would never buy a used rental car based on the way I drive them. 90mph in reverse running late to the airport, every warning light blazing, "Yeah it's fine sure I filled it up no prob gotta jet."
@ 8:30 ish the reason for the fully compressed tensioner and slack in the chain is someone turned the motor over backwards.
The joke about that hack Kilmer was hilarious.
I built the top end of that thing. 😂 well, at least the camshaft housing. (Not tower)Those cam cap bolts are pre threaded by hand before being torqued by a machine. It hurt just watching you unbolt them. 😢
Wow, wasn’t sure if I’d see a late Camry engine on your channel any time soon lol. I haven’t seen, or maybe you have tore down but I would have to look, 2.2 twin cam out of old GM compact sedans, late 90’s ford rangers engines, the GM 3.4 v6, I’m sure there are more, immortal engines out there, but I love watching your tear downs and especially the reliable engines.
"The clickbait king that has died 14 times this year." I'm dead! Never change, Eric! Never change!
How many times have you been dead??
One medical transport driver last checked in with 501,950 miles on his A25A Camry. He changes oil every 4,000 miles and uses 0W-20 Mobil 1. I use 5W-30 in mine because outside of the USA, Camry manuals say 5W-30 can be used full time, even 10W-30 in the summer.
116k miles is barely broken in for Toyota engines. Such a shame that this one suffered a premature death. That's how much mileage my 2013 Camry 2.5L had when I traded it in for a new ride 4 years ago...the engine still ran like new with nothing done to it except oil changes
