I bet someone will come out with a chain conversion kit, this is why I don't want to work on cars anymore the engineers were taught with common core principles
You know in your heart of hearts it is engineered failure to force people to spend money. Can’t have anything that lasts too long nowadays, cuts into profit margins
@@dscottmacleod321 How is this belt service any worse than servicing Ford's Eco-boost water pump? Half the mechanics say the easy way is to pull the engine, for a damn water pump.
I was thinking the same thing. Only people who don't have to actually drop the transmission would refer to it as "simply." I haven't had to change a water pump on Ford's 3.5, but I've heard it was a bitch. Engineers do a lot of stupid things. The spark plugs on top of the cylinder heads of the ford modular engines, the timing chain on the back of the 4.0 sohc, the belt and chains on the back of this diesel, etc.
He didn't say you had to drop the trany, he said move it back to reach in and change the belt. Just Saying. Now with that being said. it does seem like a pain but atleast its not being run on one belt.
@@larrydecomic1791 Moving it back is still a laborious task. You'll have to disconnect the driveshaft, probably remove the transmission mount crossmember, and replace the bell house bolts with longer ones that can support the weight. You might as well drop if you're going thru all that. Nothing is ever as easy as they guys in lab coats make it sound.
@@brussell639 I Dismantle trucks for a living. Moving the transmission is no big deal, especially if you are just moving it back far enough for service.
@@steven530x I suppose some clarity would help. If you do it for a living, it's going to be easier than for an enthusiast or DIYs. I never did it for a living, but I've changed enough transmissions that I certainly could have. And I always considered it a big pain in the ass. Especially those bellhouse bolts that you can only get to with a wrench and only have about a 1/16 - 1/8 of turning room. I still do all the maintenance on my vehicles. This would be something I wouldn't look forward to.
@@steven530x The 6.6L Duramax, 6.7L Powerstroke, and 6.7L Cummins engines, all in pickup trucks, use timing gears. There's quite literally no reason other than cost and minor noise reduction to use a belt or chain over gears, they are an inferior design.
The newer Ford 2.7l ecoboost gas engine has a wet belt oil pump drive, I still prefer to keep my truck about as simple as i can so I don't drive one of those either.
Anthony.. Bio kits (belt in oil) will be all you will see in the future. Noisy/heavy/horsepower robbing timing chains and gears are quietly riding into the sunset. The Timing Belt in Oil was developed to replace the metal chain. The rubber is made to last and run in oil for years.
Transmission has to be backed out as well as the transfer case. Driive shafts need to be removed as well as the torque converter. They should have used a timing chain on that oil pump.
I was sold on this efficient redesign until I saw oil pump belt! This engine was designed to make money via service at 150000 miles. Why couldn't they use ALL lifetime chains? Now I change my mind screw this engine, and the extra $3000 GM charges for the upgrade. Any fuel savings you gain will be all lost from the cost to replace that oil belt! will be at least another $2000 or $2500 to repair. Idiot engineers and GM executives.
I agree that’s the dumbest thing I have ever heard of. (Yea let’s put a rubber belt to drive the HOT OIL pump great idea pure genius right there 👏🏼 👏🏼 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼
@@OldSoldier54 yes i agree , i also like older vehicles . now if we can get enough people to join in on certain values and work together helping each other , life as we know it would be better for all good poor people .
Its the Colorado timing chain all over again... just watched that vid. So sad to see the same mistakes being made. Gears cost money, cost = bad. GM, please don't let these folks anywhere near the LS engine.
when he said... "all you have to do is drop the transmission" i thought the EXACT same thing... NOOOOO THANK YOU..... why would you not put a metal chain in there like everything else? what a bunch of fuckery....
@@ismaelosman9848 No. It's extremely over priced the way it's packaged in the upper trim and you can buy an f250 diesel for less and tow more. The F150 it isn't designed to last more than 150,000 miles, has a timing belt rather than gears, its new technology which isn't exactly in Fords favor and compromises durability for weight savings. Buy the 5.0 gas engine if you're looking at half ton trucks.
Rear timing chain, mechanics are gonna love you for that one, way to go GM, you did it again, it scream Canyon, which had similar, can be bought cheap because the repair is more than the value of the truck!
GM just needs to go ahead and include one belt change, between 100k and 200k miles, in price of truck. that would go a long way to ease customers minds.
Seriously? No way GM would extend a warranty like that.. Especially when these engines- with thier impressive price tags and performance- start grenading by the thousands from designed-in fail points popping apart ? If Any of those 3 critical timing chain- oil belt fails, the engines instantly a boatanchor....pistons scored, valves bent, head/ block cracked..
@@russianacorns8080 when the top of the piston hits the open valve, the valves bent, the piston distorted, sometimes the con rod bends / breaks loose, bearings squished out of round, actual block cracking is rare..
oil pump driven by a belt, man it figures GM would be so brilliant. They will sell more engines that way because not it cannot last, then again with the GM = gov motors name I would never expect it to be worth anything.
Ram has a rubber hose under the intake that supplies hot oil to the turbo. $2k labor to change it and it fails anywhere between 25k and up miles. Rubber hose is a wear item - no warranty.
Timing chains do not last that long. It's either going to be the tensioner, guides, or the chain stretch that will compromise the system. Timing gears are very reliable, but they don't use them.
What they meant was the Chains will out last the belt and when the belt fails and you loose oil pressure under load the engine will be so damaged that it will be it's "life" and thus the chains are lifetime.
I’ve had mine for two years and it does great. I own 3 semi trucks and what Chevy did with the EGR and after treatment is very cool. They’ve simplified and made those systems much more reliable. Having recirculation after the filter, so close to the turbo, and no hydrocarbon injector eliminates so many problems. Also, I’m not sure many people have owned a vehicle long enough to service something like a timing belt. I had a 2003 VW Jetta that needed a timing belt change. You have to almost disassemble the car to get to it and it takes a mechanic almost a whole day to do. With this belt, 150k mike service, you drop the transmission, replace it, bolt it back on, that’s absolutely easier than what you have to do on many other vehicles. And the coolant system, on an 18 degree day I can warm up for 3-5 minutes, drive about 2.5 miles, and I’m already approaching full temperature. It gets hot almost as fast as a gasoline car. I have nothing but good things to say.
Dropping a transmission is not as simple as you make it out to be. Especially with these new automatics with so much shit plugged into them. Absolutely retarded design and once they hit 100k miles they're going to be not worth what you owe on them
You mean all those connectors that are designed to be disconnected if need be? Oh No!! Not all those things🙄. I own one. I love the truck. Probably won’t own it when it reaches 150k. Even if it did, my 14 year old son and I removed the transmission from my f250 to rebuild.. anything is hard when you don’t know what you’re doing.
Let's be real here. A 4L80 from 1998 is an 8hr job for remove and replace. Remove and replace on the 10L80 in the 3.0L Duramax is a 12hr job. The oil pump belt adds 0.1 hr. A timing belt job on a 2015 Jetta TDI is 4.8hrs. 12hrs is not bad for something that has a 150k/15 year service interval anyway, especially in a truck that saves you $10-13k in fuel costs over that same time.
Bullshit on the jetta Tom. Nice try, I know all about those jettas. They are not hard AT ALL. Good one. Why would you even say that? Literally the easiest timing belt ever
The belt won't be an issue for most new buyers. It's the guys that buy used around 100K miles that will need to keep the oil pump belt in mind for replacement cost.
I get your point. Also when they have that thing down they could probably fix other things as well. Everyone’s looking for amazing reliability and nonexistent maintenance
Most people won't have to deal with it, the original buyer or leaser will only have the truck a year or 2, then trade it back in, they don't give a damn that the whole oiling system is 1 rubber band away from catastrophic failure, and we know it will be catastrophic because by the time the driver figures out there's a problem the engine will be seized. No matter what nonsense "warning" they mentioned that it'll give if the belt breaks we all know that most people never pay any attention to the idiot lights on the dash...even if they did, the idiot light won't tell them what's wrong, so they'll just keep on driving till the engine locks up.

Thank you for your review on this engine. I just bought an AT4 with the Duramax. I love everything about the truck especially this engine. Hopefully now I will understand its workings better especially since this is my first diesel.
GM loves 150k gotchas. Enjoyed my 08 Grand Prix till I found out the torque converter was designed to fail at 150k-170k. Got to drop the whole A frame to change. I expect this truck will be similar. Will buy RAM or Toyota for my next truck.
I have never seen so much crap on a strait 6 diesel. The reason I like the Cummins is it’s a strait 6. simple, dependable, and fairly easy to work on. this thing looks like Nightmare.
@Mr Sunshines News flash, Sunshine: By the time your "oil pressure light" (idiot light) comes on, your bearings are already fucked... unless you think failures only happens when you're idling in your driveway. No, in reality they happen when you are working the truck, like pulling a load up a grade... so there goes that brilliant advice!
@@jedediahhoffman7925 Do you watch your oil pressure gauge all the time you're driving, when the belt breaks the oil pressure will be 0 within seconds.
@@benjaminwayneb yes i do. obviously not non stop, but i keep a close enough eye on it that i lost oil pressure, i could avoid major damage. you got to think.... if you change your oil, new filter and oil, how long does it take to get oil through the system. 2 seconds? 3 seconds? at start up.... 1.5 seconds? 2 seconds? you think having it run for 7-10 seconds with no oil pressure, one time is really that much worse than every day running it for a total of 10 or more seconds dry? now my wife.... she'd prob blow the thing up.
Come on guys, replacing the 150k mi oil pump belt won't be big deal since the trans will come out every 50k mi anyway! Just replace the belt every second or third time the trans is out! lol
@@mtcruse I know they didn't but a 4L60E would definitely turn me away! I'm dealing with one now on my 1991 Chevrolet Silverado C1500. I rebuilt the original one three times and then purchased a rebuilt 4L60E to replace it. Now I'm waiting on the manufacturer to send me a replacement to the replacement! UGH! I think Fred Flintstone's foot powered stonemobile is a better choice!
Farmer Ted . Couldn’t agree more. As a technician I’m always amazed how engineers can make repairs so difficult. GM came up with a three piece thermostat housing. KISS principle should be taught the first week in EVERY engineering classes.
Supposedly it lasts 150,000 miles minimum and is 'easy to service', but I agree that's so dumb. The vehicle is out of warranty by that point, so if your oil pump belt breaks at 113,000 and grenades the motor, there's not a dang thing you can do about it.
this engine looks amazing, honestly, the only potential issue here can be the timing belt, however, technology keeps improving and we have to improve with it, I'm giving this engine 2 thumbs up
Dude, did you pay any attention? It doesn’t have a timing belt. It has timing chains, two of them, in series. Fist one drives the high pressure injection pump, second one drives the cam shafts… (Why in the heck did they design a Diesel engine with DOHC when the main benefits of the complexity is only realized at high RPMs which diesels don’t run at?)… I digress, THE BELT YOU REFERENCED DRIVES THE OIL PUMP and is oil bathed. When, not if but when, this belt fails it will MOST LIKELY result in significant engine damage due to rod and main bearings being starved of oil. Best case scenario is to replace a belt before failure but as a professional mechanic I will say the average consumer will have long forgotten this critical service when a vehicle reaches this mileage. 2nd best case scenario when an engine losses oil pressure is immediately shut the engine off and coast the vehicle to a safe location away from traffic. But consider, how much of our driving is on busy freeways with no safe locations within coasting distance? i.e. construction zones with barricades. To add another possible point of failure this oil pump is variable displacement which depending on design details and quality of components used may work out fine but could also easily be this engines achilles’ heel. For those that may not know: When a traditional timing belt fails on an interface engine the engine immediately stalls and significant damage occurs due to valves colliding with piston crowns. When timing belts fail on non-interference engines the engine also immediately stalls but most of the time no further damage results, replace the belt and continue on.
@@preachers4135 Yes , well said. All I kept hearing is Valve this and Valve that. Wonder if they will even have the parts to service or repair. Just to complex to me, I will have to pass.
@@preachers4135 Yep, belts in oil ALWAYS fail, and way faster than the manufacturer says they will, the acids and other compounds in the oil coming from combustion make these degrade rapidly, it's a really dumb design. No engine build with a wet belt, no matter what that belt powered, was ever reliable. Just facts. When that belt fails you lose oil pressure and your engine goes bye-bye. No reason to not have a chain on there besides cost reduction. A clown made that decision. Same with the variable oil pump, more complexity and those can fail too, just to add another 0.2 mpg. Like I said, a 🤡
The varible cooling makes perfect sence, 277 hp and 30 mpg highway is a feat, 15 mpg with 8,000 pounds in tow is astonishing. Thats nearly a 50% improvement in fuel savings. For being a $2,500 option it pays for itself long before 150,000 miles. This really pays for itself if one tows the majority of those miles.
Everything on that engine looks expensive and labor intensive. Yeah it payed of for a few tows but you won’t like that 10,000 dollar repair bill when it eventually comes
Reminds me of the thousands spent to bulletproof a 6.0 Ford. Someone is going to invent a bulletproof kit for this piece of work. Great job on this design doesn’t it come with a high pressure line for the driver to lube his butthole before getting rammed at the dealership service department???
Two things I dont like: 1. The oil "belt" drive. Basically a built in time bomb. 2. The turbo exhaust plumbing curving to the front instead of flipping the turbo and having the intake side on the front and a direct exhaust discharge to the rear. This keeps under hood temps down, which enables longevity of all other components.
He said you'd know the oil pump belt was failing with "appropriate Diagnostics" what the hell appropriate diagnostics telling you a belt, inside the engine is failing????? Oil pressure drops to zero?
before timing chains all engines use a timing belt, some engines still use a timing belt today! so are you saying all those engines are time bombs...? even timing chains has a service interval.
Timing chains require tensioner, a wear item. Belt does not need tensioner. The big reason however is the variable displacement oil pump. It’s easier to execute w/belt than chain, gear or Jack shaft drive
Even after you pull the transmission, you'll still be replacing two chains and a belt from underneath the truck with the engine against the firewall. If you're going to do all that, you might as well pull the engine. Anyone who thinks this job would be easier than replacing a front timing chain is nuts. And a belt driven oil pump? If that belt ever brakes, it's not going to give you any warning. If it brakes you'll have to pull the engine anyway because it'll be junk. The only reason to design something like this is to sell parts and service. They are building vehicles that you have to take it to the dealership for any work or buy another truck.
I don't think the transmission bell housing area, after transmission is removed, is "against the firewall" and the belt is in the lower half as well.. you wouldn't have to remove the chains to change the belt.,, If the chains fail the engine is coming out anyway.. pretty much guaranteed. I don't know if the oil pump belt is as big a deal as people are making it.. engines with belted timing belts can be a pain it the butt and expensive to change as well. It's one of those things that after you reach a certain amount of miles you want to bite the bullet and pay to replace BEFORE they fail.. I don't think you would want to chance the oil pump belt failing on this either.. not because of "burning up the engine from no oil".. I think I would be more worried about what's left of the belt going up into the timing chain and causing catastrophic damage.
I have one in my 2022 Escalade ESV. I love this engine!!! It’s blown me away in every area that I have previously had issues with on my Cummins and Powerstrokes. This 3.0 is something from the future I’m telling you. If I gave you the keys you would swear there is a much bigger engine than a 3 liter. GM has hit a home run with this. Go buy one and see what I’m talking about. It’s really that good. Thumbs up GM 👍👍👍👍👍👍👍👍👍👍
Cmon man these engines are in fact good but we all know you didnt have issues with a cummins... only issue with the cummins is emissions control and they are the lesst problematic out of the bunch as long as you run them hard to keep the dpf filter clean
I wish I could get paid to say good things. But no really I'm sure it is great truck to drive and enjoy. But it's prone to have bad problems. It's all in the point of elimination. And don't forget it feels much bigger than a 3.0l becouse deisel is almost superior in every way. Mainly the torque and efficiency. This one will lack in reliability/longevity.
@@masonbsker64 I am not paid to say anything if that's what you are insinuating. I am just trying to explain how happy I am with this purchase. It's rare something goes as planned these days. So when it goes better than expected I like to give credit where it is due. I am just an average guy who lives in New Orleans Louisiana. I am in the Telecom field. Nothing about my post is paid for or compensated in anyway. I bought a new truck and the engine is awesome for a change. That's it. My Fords had major problems with various issues. Power Strokes have had major issues everyone knows about. The Cumminns is awesome in my boat. But not so good in my trucks. Sorry but it's true. Yes most issues were emissions related but GM has to play by the same rules. Granted this truck is new, but I'm telling you it's awesome so far. It starts instantly. It's so quiet you would almost swear it was a gasser. And it pulls all the way to 5K RPM like a gasser. Just go test drive one. Then come back and tell me if i'm lying about anything I said. And again, I haven't ever been paid one red cent by anyone for this review. Just the opposite. I spent a fortune on my 2022 Escalade ESV. I wish someone would pay me for my review!
It sounds like this engine is extremely well thought out, unlike Ram’s sorry Ecodiesel that likes to implode & never gets the listed mpg. I drove this engine in a GMC pickup & the wife was ready to buy it! You couldn’t even tell it was a diesel!
@@juliemathis1065- Have you heard of frequent oil pump belt failures? I haven’t, but I’m not ready to buy yet. FCA has redesigned their Ecodiesel for reliability & emissions.

Access the belt by simply dropping the transmission? Great idea!! The engineers should get a medal for making it so simple. Idiots , how much will that cost? Imagine how hot under hood it will be with all that emissions garbage on there . Have fun who ever buys this disaster.
That's what I thought initially. But actually, dropping the transmission would probably not be any more difficult than if everything were up front, where you would have to remove the the radiator, fans, etc. Of course, we're talking for a technician, not someone in their own driveway...but it is doubtful that most consumers would attempt a job like this. I do agree with you about the under hood heat, though. That could end up being a problem over time.
The RV Connection , at least the front parts are manageable for the average backyard mechanic. A transmission not so much. Just gm making it overly complicated so you need to bring it to the dealership and eat a huge bill. Shop rate here is $160 an hour, so it will be expensive. I think about the poor person that’s going to own these trucks after the warranty is expired .
The engineers told me the main reason for this is that there is less harmonic distortion on the back of the crank than the front, which makes for more accurate timing/fuel delivery.
That may have been the case with mechanical jerk fuel pumps due to crank oscillations, but not with common rail as there is no connection to injector timing it’s all electronic, the high pressure fuel pump only supply’s fuel to the common rail, ie an accumulator rail that feed high pressure to the injectors.
Timing gear on the back of the engine is not new it’s been around a long time on truck engines, normally gear driven and very reliable, but chain drive WTF... timing belts immersed in oil have been used for some time also, look at a Ford Transit Connect 1.8 TDC and very reliable, but it’s on the front of the engine.
@@andywt8460 Correct, and now a year later, we are finding the BIO (Belt in Oil) kits with special rubber compounds will outlast the motor.. I can't believe all the kids here posing as clairvoyants and engineers trying to impress people.
In the first minute of this video I went from being excited about this engine to completely writing it off as another designed-to-fail turd. All the comments about the engineers being on drugs are spot on.
Oil pump belt breaks pulling a trailer up mountain warning lights come on as you try to get off the road engine seizes up I think you might have to pull more than just the transmission. So much for long term reliability
I stopped the video after I heard “we have a rear timing system”...engineers, I get it, you want to make a name for yourself and look good for the boss. But eventually you’re going to look like a moron when the warranty claims start rolling in. Sometimes “ingenuity” isn’t worth it. Start thinking like a normal person. Just because you can doesn’t mean you should.
Retards that think they have a better solution tend to say shit like this. You generally have to drop engines to change chains and pumps anyways, it isnt like this unusual service procedures. GM probably didnt expect everyone to be such an unreasonable moron when they designed this.
@@Heatherder to change oil pumps yes, (good oil pumps rarely fail) but changing a belt for the oil pump is unheard of much less decoupling the trans to do one every 150k miles. You're insane if you think that's normal or even reasonable.
Belt is rated for 150K. At which point, you have to pay Mr. Goodwrench $3,500.00. $2,000.00 of that goes straight to GM. The Engineers were told to develop future revenue streams for the shareholders. I'm so over Government Motor's Bullshit. I have been a Chevy guy since the 1970's, but the next truck I'm buying will be a Ford F-250.
@@trp2413 I had an 2008 Silverado. GM designed the truck so you can't change the spark plugs, brake pads, headlights, they even put a bar over the battery just to make changing that a pain in the ass! GM: want to stay in business? Make these changes: 1.) Build trucks that are easily owner serviceable. 2.) Build trucks with the best quality, high reliability parts possible. 3.) Include a diagnostics menu in the truck's Infotainment System so the truck tells the Owner exactly what has failed or what is going to fail. If you do these 3 things you will build a loyalty like you haven't seen since the 1950's. What's better; squeezing revenue out of your customers with overpriced and unnecessary trips to the Dealerships for repairs that piss off your customers, OR Building an honest truck that makes a truck buyer feel like the Manufacturer has done everything in their power to build the most reliable truck possible, and if the truck does have a problem, it is easy for the owner to economically repair himself. Lose the idiot lights, replace them with a detailed diagnostics read out in plain english. If you do this, your only problem will be how to build enough trucks to keep up with the demand.
Sorry Sam bains, Ford is the only one left who has to pay the the government back money they borrowed. It was 5.9 BILLION dollars they took in June 2009. This is verified in an article in Forbs magazine. Look it up. There are about fifteen different other reputable news and money market companies that report the same. They borrowed the money the the exact same month as GM and Chrysler. Ford has to pay back 577 million by the end of this year and finish paying off the entire 5.9 BILLION by June 15 2022! GM has already payed off there debt. Chrysler sold out to Fiat. Ford is the only one to pay what it owes back. It's been 10 years. Don't believe me??!! Go ahead and Google it. Ford is the real "GOVERNMENT MOTORS". So should think twice about buying a government motor Ford pop can poor excuse for a truck.
@@gilvietor1918 I thought the same thing with the 6.2L but it should be faster to pull a head than dropping the trans. I really was contemplating the diesel because I wanted to own a diesel. I probably would have been happy with either.
I'll give em credit for figuring out how to get the EGR after the DPF. Soot ingestion is a major deal on BMW diesels and intake manifold/swirl system get clogged up by 150K miles and EGR coolers rarely go past 100K. Also, good choice with I6, this is a big NVH advantage over the Chrysler/Fiat V6 and certainly improves packaging of the SCR, DPF, & turbo.
Why does it even have EGR? It’s been proven that robust SCR can be used to eliminate EGR, EGR coolers and all the associated re-ingested soot nightmares. This engine employees all the worst mechanical principles and technology that contribute to an engines longevity, reliability, cost of ownership, repairs and maintenance. IMO if an engineering team was tasked with developing a power-plant that would kill the ambitions of the diesel truck consumer this is the engine they would dream up.
Its not the EGR by itself getting those clogged up, it's the PCV valve that's not a service item for most dealers that cover everything in fine oil mist after 30-50k miles of life, which then it traps the soot on the oil.
I was considering this as my next truck. GM guy through and through...but I have to agree with others. That timing system looks like a disaster waiting to happen. Give me a lifetime warranty parts and labor and I would consider it. But, this just confirms that the V8 duramax is just better all over the place and worth the extra coin.
Right I'm looking in the next year or to to buy a new truck and I was considering one with this engine but after seeing that the oil pump is ran by a belt I might not even buy a gm 6.7 gets great fuel mileage deleted
I work on diesels every day and servicing that oil pump belt is no big deal, this engine is a great design and better than ford and Ram small diesel engines
@@mylarson7640 Larson the fact that you commented On someone else’s comment from 3 months ago trying to argue that this $3,000 upgrade of an engine to save you thousands in fuel makes you you look like a dumb ass I’m disappointed in you stop commenting on the internet
@@mefobills279 I'm not much of a GM fan anymore, but aside from that if the engine wasn't wound up high and hard all the time pulling, the belt is probably fine for 200k. They've done 150k mile inspections and the belt looked great. Typically daily commute, tow ever so often like an average user and 200k wouldn't scare me
They say 150k but I know of at least 3 timing belts that had 75k service intervals and I never touched them well past 250k. Also their was a DMax rep on another channel that said they tested the belts on their test engines at 300k and there was no deflection/stretch in the oil pump belt, also part of the design is to keep the belt wet with oil from the sump which prolongs it’s life. Much ado about nothing tbh. And lastly to service the oil pump belt you only need to move the transmission about 1.5 inches back to get access to it.
Perfect engine for the pie plate starter generator hybrid. I would like to see GM put it on the front of the engine. Everything could be electric and eliminate the serpentine belt. If they did it properly it could be maintained much easier than any other engine and everything could be more strategically located. For instance the air conditioning compressor could be located within the heating system and made to be easily worked on.
Thanks for the video. I've been looking to pick up a new Jeep Wrangler with the diesel, but since they didn't offer a manual I've written that off. I was thinking about the 3.0 duramax as a secondary vehicle. After this video, that one is off the list now too.
At first I was thrilled to hear that this engine was a straight 6. After listening to the engineers it sounds like there is just way too much to go wrong. Something tells me this won't have the same reliability as the 4.0 in my Wrangler.
This is a modern diesel that employs the latest design techniques to maximize power and fuel efficiency while still being lightweight. The 4.0 is a gas engine derived from the original 2.5 of 1984. Reliability of most engines today is much higher than earlier designs so assuming good maintenance practices (especially important in diesels) it will quite likely be enormously reliable.
CAN YOU PLEASE do this for the 2.8L as well? I dont have the 3.0 and found this super interesting. I have the baby D-max canyon and would be super interested in that video aswell
Hey Kody, unfortunately, no. The media people frequently roll out cutaways or models of engines when they're introduced, but not afterwards. If you look around, however, I'm sure you'll find someone who has done an overview of the 2.8. Thanks for watching!
The amount of hate for that stupid rubber oil pump belt, super strechy chain at the REAR of the engine, makes me laugh like hell. What a piece of shit. Like GM has an awesome reputation with timing chains since 2009.
@@dalemarshall625 Because it takes a lot of gears to get an overhead cam setup to work. Look at an old Cat 1693 with the DOHC, had like 3 idler gears just to get power up to the cams. It is obvious these were built only to the price point and first owner needs. They don't care about anyone that would own one of these after warranty is up.
I don't mind working on engines. The problem is getting the customer to understand all the time it took to remove the failed part and put it back together. Just like the timing belt on the Subaru sti. Also if the engine and components are so great, the warranty should reflect on that.
I've had mine for a couple years and just bought a suburban with it as well. If it needs a belt at 150,000 miles then so be it. Its only a 995$ option on the SUVs now so its dumb not to get it as an option. Its awesome. Period.
My friend got one of these in a 2021 1500 truck, its very quiet, actually makes a good sound under power. At least the rear timing chain is simple, not like a Audi 4.2 etc. The timing belt is wierd, but with regular oil changes it could probably last a very long time, I wonder on this truck if you could just back the trans off 6inches etc to service it, drop a few driveshafts or its a huge deal, pull transfer case etc to change the belt. You can see all the clever packaging to get into a compact modular unit that can go into just about any commercial\personal vehicle, the emmisions control is pretty neat with all the interesting coolant control (scary to have engine oil cooler like that, if gaskets fail...) Hopefully they're specced top quality parts on this thing for belts\gaskets or it could be, not so good.
@@chrisguillen1495 It shows a OEM doesn't give a crap about after the sale with a design like this, considering this thing is also meant for Commercial application and likely built to a price, pushing 30psi of boost stock (lots of CFM I'm sure) its not good.
@@chrisguillen1495 Dropping a tranmission is "monster amount of labor" every 150k-200k miles? Man how were clutches replaced in the old days, must have just junked the car every time it needed a clutch!
At 156k on my 1986 6.2 Detroit diesel, it has seen a one replacement starter, two sets of glow plugs, and a new aluminum radiator. With a battery tender hooked up, it can sit for months and fire up when needed.
