@@Mr.WS6 ram gave that lifetime powertrain warranty for three model years only 2006, 2007, and 2008 and it was only on gas trucks. The lifetime warranty that some other rams have is essentially an extended warranty and it is purchased at time of vehicle, has three levels of coverage.
So much of this new stuff looks and sounds fancy, but in reality looks like a nightmare to me. I love chevy, but think about that little swirl valve in the intake getting stopped up with pcv and egr carbons, then they have all these little extra solenoids on the coolant system. if one fails, your car will still function normally , but one component will get no water at all.... Looks like a nightmare to own and maintain. It probably will be good for 150,000, but beyond that maintenance will be prohibitively expensive :(

Watch the video again at 7:20 he talks about regen. If you look back at the old way of regen(cleaning out the filter) gm in the LMM 07.5 to 10 Durimax had this system and ford had it in the 6.4 power stroke 08-10. When they inject the diesel into the cylinder on exhaust stroke it washes out the rings on that cylinder and will cause the engine to fail. Many as low as 20t miles. Almost all by the time it got to 150t. So I’m disappointed to see gm go back to an old system that they already know does not work and bring back a problem that they have already got an answer to.(adding an extra injector to the exhaust pipe after the turbo) very disappointing I was hoping to get one of these diesels when they come out but now that I have seen this I will be waiting till someone cracks the ecm so I can delete the dpf and egr before I spend my money on it. Or wait till gm adds the 7th injector to it.
I'm enjoying my 3.0L Silverado. I'm at about 18k miles and I'm getting 26mpg over the whole year I've had it. If I drive flat distances at about 75 I'll get 33mpg, city I'll get 24-26. I've also never felt like I'm ever lacking power. I actually feel like I'm always in the power band. The 10 speed transmission probably is my favorite part of the setup. I've towed a buddy's boat and it brings me down to about 18-20mpg. I've also only refilled my DEF twice in a year. I'm a pretty light user but then again... it is a 1500
This looks like a very interesting engine. We'll have to wait a few years to see how reliable it actually is, but it looks like a nice addition to the half-ton truck engine choices.
@@blackhatter011 2020 at4 3.0 duramax, 24.3k miles zero issues, all highway mileage with moderate towing 6500-8500lbs. Seems like a very solid engine but time will tell. We shall see…..
36,000psi hitting the top of those pistons. How long before it cuts through? For reference a Water Jet can cut metal as low as 40,000 psi in one pass. The injectors are hitting the pistons continuously while the engine is running at 36,000 psi.
New to the channel. Thanks, great information. Can you ask the engineer one question? When turbos first came out, most of them did not last since after driven hard and shut down, the turbo would cook and would not last Long. Then they came out with turbo savers, which would circulate oil after engine shutdown until it was cool. How does GM prevent this from happening. Will oil still circulate or should we (when I get one) let the engine idle for a bit before shutting down. Test drove one yesterday. Loved it, just not the MSRP price.
I would consider this engine. I'm a retired diesel mechanic with well over 40 years experience. I like the approach GM used on this engine overall. I've had an ecodiesel and loved it, luckily mine didn't have the bottom end problems like some of them did. I'll be buying a 1/2 ton diesel pickup this fall, it will be between the GM & the Ram. I want to drive both of them before I totally make up my mind, but at the point Ram has the lead. GM IMO is behind the curve on their interior compared to Ram & that's where you spend your time when driving one.@@4WDMagazine
Nope, If you've watched some of the other videos about this engine you would know why I said what I did. This was a good review, with some good information, only time will tell if it's a good engine in the long run.@@skiprope536
@@bigez526 I could care less on towing it would have a 100hp more and 100ftlbs more torque. That engine would be awesome in one the mpg would be crazy high. With that much more power you could run a little higher axle ratio.
I’m a Diesel nerd and I’m glad some Diesels are being used in trucks. So if you were to Delete the DPF it would unlock the great sound of the motor, the better MPG, and more power. If anything a healthy Diesel does not need a DPF. The gas trucks should be using them because they use more fuel.
I'm extremely surprised to hear they went "back" to an extra injection event for DPF regeneration like on the LMM Duramax. LML/L5P use a 9th injector in the exhaust which seems like a no brainer after all the fuel dilution issues that the LMM had.
DPF Means "Save the seals but kill the whales" I say this because oil & fuel can't be replaced so we are using it up & DPF system causes the motor to use more fuel plus causes more wear on the motor.
The rear chain is concerning and GM didn’t think to make it a double roller? Also the valves that send coolant to different areas sounds like a nightmare down the road.
Nice to see GM trying to do something innovative. Government requires all engines to meet emissions for 150k I think so they aren't anything un usual. The wet belt in a concern but lots of makers seem to be going to them so they may work better than expected. I would be more concerned that the Timing chain is only a single roller mounted on back of engine meaning motor would have to be pulled to replace it.
The origional Duramax was a proven Isuzu engine coupled to an Allison transmission. This Duramax is a design from scratch GM diesel coupled to an unspecified transmission. I think I'll wait a while.
B Laquisha I would go back and look up the history of the Original Duramax again. That was a true joint venture between GM and Isuzu. They have all been built in the Moraine, Ohio plant that my brother works at. There is an Isuzu built engine that is an I-6 that is “called” a Duramax but it’s not the original and isn’t paired with an Allison transmission. Very good engine from what I hear. Like you, I would also wait. I love GM but look at their history when it comes to Diesel engines that were built without Isuzu’s help, not very good.
B Laquisha a 60-40 joint venture between GM and Isuzu in Moraine, Ohio. The Duramax block and heads are poured at The Defiance GM Powertrain foundry in Defiance, Ohio GM taking a 34% stake in Isuzu was seen in 1972 In 1998 General Motors and Isuzu formed DMAX, a joint venture to produce diesel engines. GM raised its stake in Isuzu to 49% the following year, effectively gaining control of the company
Hold up, does that mean that the regen cycle works by injecting fuel during exhaust strokes? Oil dilution springs up to mind. No wonder max oil change interval mentioned is 7,500 miles. Why not using a 7th injector?
Don't forget Ford did this on the first gen 6.4l Powerstroke's, it didn't work out to great for them as they would metal the oil seal on the turbo and then turn into a smoke machine. Ford used the back two injectors to push fuel out on the exhaust stroke for re-gen.
Aluminum block & heads in a diesel? I listened to the engineer describe all the "gizmos" to do this , that, & the other thing. I predict this engine will be a "GMC ......garage mechanic's companion' ! I buy a truck for reliability, & I will accept lower fuel mileage, higher weight, & fewer computer controlled crap, in order to get it. I drove Ford trucks all my life (I am 80 yrs) & I bought ONE Power Joke. I traded it after 6 months, at a significant loss, to buy a new (97) Dodge 2500 with a Cummins 12 valve. It has 1.5 million miles on it & still runs fine. I replaced the water pump once, the "O" rings on the delivery valves, the bell crank on the AFC unit twice, (the ball stud on the throttle rod connection wore out), 2 alternators, & it is still running on the original lift pump (admittedly it needs to be changed now) the original injectors, & the original starter....(starter is showing signs of distress) It has been the most reliable engine I have ever owned. The rest of the truck has been relatively trouble free. Right front inner axle seal twice, both front steering universals three times, steering box replacement, clutch complete at nine hundred & some thousand miles ( I live in a rural area & use the clutch only to get moving & then throttle shift through the rest of the gears) * I bought a n aftermarket exhaust system & fuel plate from Banks engineering the first week after I bought the truck, & it is still in good shape, with no obvious exhaust leaks. I live in southern Alberta, where little or NO salt is used on our roads (big cities excepted), so I expect that owners of this new Silverado engine will never make a "million mile " club ! I am aware of a number of 12 valve trucks locally that have gone a million miles without any major issues. The new High pressure rail injection engines are a nightmare, with pumps, pressure regulators, injectors (piezo units break, pintles break) SCR units burn up , etc etc. I will drive my Dodge until either the truck or myself expire ( my guess is that I will go first !!). Interesting interview.
Brian Hind : Chevy guy here, would always have faith in a Cummins. It's what they put that amazing engine in that bothers me. Transmissions and front ends come to mind Edit, for those that maintain their vehicles properly (like this guy with his 97 12 valve) vehicle will usually so very well like in his case. I've got a 98 Silverado 7.4L with 320,000 on it and changed the original factory alternator and water pump last year. Oil changes every 5000, being attentive can make all the difference
Eye opening information here. 150k miles is not long to recoup the added cost of the engine. If you drive alot then after 3 years you'll be paying a mechanic to rebuild it. Good to know! Thanks!
I think the engine has great potential, the problem comes 8 months to two years down the road when the Criminal EPA/CARB Cartel says wait a minute and makes GM reflash the computers when they are in for service and the truck owners end up losing 3 mpg's plus acceleration loss.
For the price of the truck I would be highly disappointed if the engine didn't last any longer than 150k. Besides my current one owner has set the longevity bar pretty high for my next new truck. ✌✌
mr.18436572 any well engineered car today lasts 150k running as new. The true limit is about 300k. Pretty simple. For poorly engineered cars they run correctly to 75k and the die around 120k.
Help I’m getting a 2021 Denali. Order the Diesel or 6,2 then ? What is better ? I like the better mileage but I’m not towing anything. Which one is more reliable ? So many questions ... 😬🙄🤨
Was going to buy one but this isn't the first time I've heard this 150k miles comment. Never heard the reps do that before. I commute so that is three years for me, seeya!
Buuboi214 the new 10 speeds are nice. I have it in my 17 F150 and now have 55k miles and it’s never had an issue (unlike the 6 speed in my 2011). Ford and GM partnered together to build the 10 speed.
What going to happen with the water cooled intercooler when the truck is sitting or driven in very cold weather? What will happen if something cracks and leaks over the electrical system?
@@robertmoulton2656 exactly! But a big part is to deter people from doing their own work...and at some point everything will have to go back to the dealer for repairs.
I really like that they went with an in-line 6 but they lost me with a “wet” belt driving the oil pump at the rear of the engine where you have to separate the engine and transmission to get access to it. Additionally, an aluminum block on a diesel? No thanks.
Towing about 5,000lbs, mine uses about 5 gallons of def in 950 miles. That’s from Indiana to Tennessee and back. Loaded the entire time. Tows great, but uses more def while towing than what he said.
Ya that's a given...nothing lasts forever that is obviously true with any manufacturer...we of course need to get over 300k out of any diesel engine...over 500 should be expected with routine maintenance
I wish I could have one of these fine engines in a restored 1985 Buick Riviera or in a restored 1985 Oldsmobile 98 or even a 1985 GMC Vandura. I'd be in Hog Heaven
@@MrPland1992 6.5 s are fine, drove one many years and no problems except replaced the waste gate control with a Heath manual. My one ton got 18 mpg. It isn't as powerful as a Cummins but I don't feel the need to speed with a big trailer. It runs over 110 unloaded.
So … 277hp and 460lbft of torque … I'm happy with the 420hp 460lbft 6.2L gas engine. I understand max torque is available at 1500rpm but would much rather hear 375hp and 550lbft or better on this diesel. Sounds like it's not good enough power-wise
Definitely designed for light duty towing. It's a shame Chevy didn't let us tow in the drive test. Ford let us tow with the Ranger, a mid-size truck as they were confident with the Ranger's tow performance - th-cam.com/video/RFUk16d7sHs/w-d-xo.html
Good video but I won't buy one knowing that there is a wet-belt-driven oil pump that will be lucky to last 150k miles. Oil and heat do not favor rubber belts. And what is the shop time that GM allocates for the procedure to replace this wet-belt? (Hint: You have to drop the transmission.) I was looking forward to one of these diesels in a Tahoe/Yukon.
Low pressure EGR should result in significantly less soot being ingested... however I see they do use high pressure EGR during warmup so it could still become an issue over time.
I’m just speaking from experience dealing with sprinter vans in the rental fleet I maintain. Almost every one of them at some point had to have the engine pulled to get a new intake
@@RobertLeMay848 I can imagine... however the Sprinter uses high pressure EGR which causes tons of soot to go thru the intake, whereas with low pressure EGR the exhaust is drawn downstream from the DPF, thus the soot is already removed. So I would consider low pressure EGR the lesser of two evils as it keeps the engine oil much cleaner.
good luck yeah in your dreams. Would have been different if they would have did a straight six setup like Cummings did for years but no..... we get this BS. Manufacturers are getting to where more and more reliable vehicles are becoming a thing of the past. Can’t make any money on repairs and selling you another vehicle if a truck lasts well after it’s paid off.

Or wait till gm adds the 7th injector to it.
I like that they added it as a option for the LT, unlike Ford, VW and others. Only way to get TDi in the Jetta was to get a premium package which put the cost through the roof. Same with Ford. Someone who is buying a diesel engine wants economy, how the fuck do you think you will sell any of these when the vehicle costs as much as a house?? I dont care what the excuse is. I think Chevy did right here unlike the others by offering it in a lower trim. Only thing that really concerns me is two things right off. First, that bicycle chain sized single row timing chain. Not like we havent seen any failures from other engines with chains like this....Hemi... Second, how close that DPF is. Even if there are heat shields there, with that DPF up under the cowl next to the firewall, it will get hot and anything plastic there will be roasted in not much time. We'll see I guess. Looks cool though.
Wait until that masterpiece needs to be serviced..... you'll then experience what they call the "swirl" effect which describes what then happens to the contents of your wallet....SCRF means secures cash really fast.
Unless these are built in the US from US spec parts (or German-Japan) this engine is going to be a anchor. Chinese spec/out of spec parts won't cut. Plus it sounds like there is ALOT of critical maintenance (dealer only) required. So overall... more money to buy the pkge. More money to maintain the vehicle. And more visits to the dealer. If your not driving over 20K miles a year. Get the gas engine and save yourself all the upfront-long term money and headaches.
150k out of a diesel? Where is the 300k mile diesels....my gasser 6.0 made 260k before it started knocking and was pulling trailers right off the parking lot. Changed a water pump and alternator around 180k and that was it.
So, public math: 7500 miles on this diesel getting 33mpg, at $3.00 per gal plus $74 DEF is $755.82. So if your gas model gets 25.8 mpg at $2.60 a gallon, it’s equal. Then you can add in the extra maintenance costs and that the engine cost more to begin. This is at the current $0.40 gap of diesel and gas. It was at $0.60 recently. Hmmm
Eric Herrmann This engine uses “cleaned” EGR, meaning it’s post-DPF exhaust that goes back in. No soot will make its way in. But that doesn’t mean Ash will not. After 100k, the ash will start to build up inside the DPF and most certainly some will be put back into the cylinders. If you’ve ever felt DPF ash between your fingers, you’ll know that it’s like pulverized rock. So, no, the EGR valve/cooler will not clog. But the engine oil will need to be changed at 3,000mi intervals -or less once truck is around 100k if you want this thing not to have scored cylinders by 150k. I really don’t understand the lust for more complex, more energy inefficient engine “technology”
150k miles with no problems my ass. Anyone who has ever worked on new cars/trucks knows that these new engines can barely go 20k miles without some sort of emissions or electronics issue. I'd be willing to bet that putting the DPF in the engine bay like that is going to cause failures because of how much heat gets generated from a regen. Also why is the timing chain on the back? This engine is going to be a nightmare to work on.
I bet a lot of things (like electrical) will go bad before the oil pump belt. My Tacoma had a timing chain in the front and the cover leaked at 129K (common failure), still $3.3K to fix.
@@patmcbride9853 Exactly--virtually all timing chains in today's cars are a nightmare to work on. There is no room in most modern engine bays, and so much stuff has to be removed to get to it regardless of where it's located.
I just don't understand why GM is so tight lipped about the actual mpg. The reason to buy a diesel 1/2 ton is precisely mpg, depending on exactly what it is. I just took my 2019 with 6.2 and go 21 over 200 miles yesterday. To balance out the potential reliability issues with SCR, DPF, EGR, on the diesel, it had better get upwards of 30 mpg or it just doesn't make sense, unless you tow every day in which case say, 8-10 mpg towing with a gas motor will be considerably offset by 13-15 mpg with the diesel. I think GM is ultimately hurting potential sales by staying so tight lipped. People are getting tired of waiting and will buy something else if they are in the market.
I agree that it wouldn't be wise to by first year anything. But I hope that this engine will provide another way to reduce fuel consumption. Problem is, in my neck of the woods we pay 10-20 cents more per gallon of diesel. So it had better be VERY frugal.
Better get a good ol 7.3 PowerStroke or 5.9 Cummins 12v if you want half a million to a million miles. My 2000 F350 has 480something k miles on the engine without any major work. You won't find longevity out of new vehicles today, they don't make money if you drive that many miles on one vehicle.
GM never said or implied the following: (It will make it 150k miles, that is 70,000 miles of power and greatness. I promise you will get the full 45k miles from this 15k mile engine and boy will it last you at least 150 miles. ). I went to a Chevy dealership and they swore the Durmax diesel had Platinum tipped spark plugs that would last 100,000 miles. I told them if the diesel had Platinum tipped spark plugs I would buy it right away. That sales guy was so happy until he talked to his manager when I ask him to verify they were indeed Platinum tipped spark plugs. Bought a Ram when the sales guy told me about the Cummins and knew all about including def usage rates compression ratios and laughed when I ask him if it had Platinum tipped spark plugs. He knew I was kidding.
Ok. Cool engine. Glad to see GM making a light duty 3.0L for the 1500. However...however...who was smoking the weed when they decided to put the timing system at the back of the engine? Having to pull the trans to fix a timing chain is ridiculous. Better put a lifetime warranty on the timing system. I bet the stealership will be glad to ding you $2K to put timing components into this thing
I would have more concern with the DPF being right under the hood. Heat soaking the engine and intake air temps. Also burning out injectors with all the Cycling. Also seems like they maid the cooling system way over complicated. And two EGRs! Nothing but engine murderers.
Sherry Adams the old pre 2007 5.3 and 5.7 gm engines where top of the line, chassis and trans pretty decent. They went bankrupt shortly after that and got government bailout, since that they done nothing but build junk, screw taxpayers and keep their small excess funds offshore to avoid taxes themselves
Note that since this disposable little 3.0 diesel actually DOES meet emissions, you’ll be using 1.5 gallons of DEF per 1000 miles while towing. IF the 6.7 Powerstroke Actually met emissions (see Ford EPA diesel emissions settlement stories) you’d be using 2.5 gallons of DEF per 1000 miles while towing. I think the revised 2020’s DEF consumption will go way up to be where the emissions standards require them. Yikes!
Neo Craft Funny you say that about the 6.7. My former service truck was a 6.7, upon delivery it had a code for NOX sensor...... After putting 32k miles on it I finally replaced it. In those 32k miles it burnt a whopping 2 gallons of DEF. 🤪😜😜. VW were just the only ones caught.........
I was excited about the superior architecture of the inline 6. So overcomplicated though. Non starter with removing the transmission to get to a belt. Gears can be used instead of belts/chains. Fuel rail pressures too high. I'll stick with the iron 4.9 l Ford gas. KISS engineering seems to be a lost art. Maybe they're designed to be in the shop often.
I believe it's only available in the Titan XD, which marketed as somewhere between and half-ton and 3/4 ton. It's also a 5.0L not a 3.0L. Because of those two criteria I didn't include it.
Yes they dropped because is a 5.0 betuing a 3.0 and 6.7 and cost a lot of money but I love it still have 5 years warranty and 100 thousands mile I love it
He's being told VERY CAREFULLY what to say by the company lawyers . . . even a 5 y.o can notice it. Liabilities and litigation are beautiful things . . . 🙄
Great engine until they used a belt to drive the oil pump. You just took a 500K mike engine into a 150K engine. That’s going to be at least a $1K service, and for me that’s about 7 years. Who knows what happens with other systems. And how much is this upgrade going to cost over standard engine💵💵💵💵💵.
This engine is based on the same design as the Mercedes-Benz new OM-656 I6 diesel engine. GM's diesel engineering center in Turin, Italy adapted the design for GM's trucks, and the design was handed off to Michigan for final engineering work, testing and validation, and manufacturing.
Then put a 150k warranty on the engine!
Absolutely right!
Or what Ram does, life time warranty as long as you own the truck and keep it oem. Ram is killing the market
@@Mr.WS6 ram gave that lifetime powertrain warranty for three model years only 2006, 2007, and 2008 and it was only on gas trucks. The lifetime warranty that some other rams have is essentially an extended warranty and it is purchased at time of vehicle, has three levels of coverage.
Some dealerships do have a lifetime warranty on thier GM vehicles.

36,000psi hitting the top of those pistons. How long before it cuts through? For reference a Water Jet can cut metal as low as 40,000 psi in one pass. The injectors are hitting the pistons continuously while the engine is running at 36,000 psi.
Just purchased one take delivery in a few days. It’s extremely quiet for a diesel.
New to the channel. Thanks, great information. Can you ask the engineer one question? When turbos first came out, most of them did not last since after driven hard and shut down, the turbo would cook and would not last Long. Then they came out with turbo savers, which would circulate oil after engine shutdown until it was cool. How does GM prevent this from happening. Will oil still circulate or should we (when I get one) let the engine idle for a bit before shutting down. Test drove one yesterday. Loved it, just not the MSRP price.
Best review of this engine I've seen yet. Good intelligent concise questions that drew a lot of good information from the GM engineer.
Thanks Paul. What's your take on the engine? Is it something you would buy (depending on price of course)?
I would consider this engine. I'm a retired diesel mechanic with well over 40 years experience. I like the approach GM used on this engine overall. I've had an ecodiesel and loved it, luckily mine didn't have the bottom end problems like some of them did. I'll be buying a 1/2 ton diesel pickup this fall, it will be between the GM & the Ram. I want to drive both of them before I totally make up my mind, but at the point Ram has the lead. GM IMO is behind the curve on their interior compared to Ram & that's where you spend your time when driving one.@@4WDMagazine
I can't fault your opinion of the Ram interior - they do a great job. I'm also a fan of their trucks - had a Ram 1500 Larimie right up to 315,000 km.
Did you fall on your head? Twice?
Nope, If you've watched some of the other videos about this engine you would know why I said what I did. This was a good review, with some good information, only time will tell if it's a good engine in the long run.@@skiprope536
I wish they would put that engine with same specs in the Canyon/Colorado. Especially in the Zr2
Colorado HD. A bit wider plus higher hauling/towing. Maybe 3k payload with 9.5k towing.
@@bigez526 I could care less on towing it would have a 100hp more and 100ftlbs more torque. That engine would be awesome in one the mpg would be crazy high. With that much more power you could run a little higher axle ratio.
That or a Tahoe or Suburban
@@j_rod_52 ya I'm kinda surprised they haven't said anything about that a full size SUV getting in the 25-26 mpg range.
It'd be sweet!
I’m a Diesel nerd and I’m glad some Diesels are being used in trucks. So if you were to Delete the DPF it would unlock the great sound of the motor, the better MPG, and more power. If anything a healthy Diesel does not need a DPF. The gas trucks should be using them because they use more fuel.
I'm extremely surprised to hear they went "back" to an extra injection event for DPF regeneration like on the LMM Duramax. LML/L5P use a 9th injector in the exhaust which seems like a no brainer after all the fuel dilution issues that the LMM had.
Its already got 12 jd powa awards for pre-start up gas milage
DPF Means "Save the seals but kill the whales" I say this because oil & fuel can't be replaced so we are using it up & DPF system causes the motor to use more fuel plus causes more wear on the motor.
Using up the oil? New oil is being made thin the earth everyday. Buy a boat cuz those sea levels.
I call DEF Fluid "Government Juice"
The rear chain is concerning and GM didn’t think to make it a double roller? Also the valves that send coolant to different areas sounds like a nightmare down the road.
I can just see the TSB: Customer concern oil leak at rear timing cover. Removal of Engine required.
Or, customer concern of big red light on dash. Drove it in anyway to diagnose oil pressure light.
Industry and the epa has taken the simple reliable diesel engine and made is an overwhelming night mare .
It will definitely more complicated to work on.
Nice to see GM trying to do something innovative. Government requires all engines to meet emissions for 150k I think so they aren't anything un usual. The wet belt in a concern but lots of makers seem to be going to them so they may work better than expected. I would be more concerned that the Timing chain is only a single roller mounted on back of engine meaning motor would have to be pulled to replace it.
The origional Duramax was a proven Isuzu engine coupled to an Allison transmission. This Duramax is a design from scratch GM diesel coupled to an unspecified transmission. I think I'll wait a while.
B Laquisha I would go back and look up the history of the Original Duramax again. That was a true joint venture between GM and Isuzu. They have all been built in the Moraine, Ohio plant that my brother works at. There is an Isuzu built engine that is an I-6 that is “called” a Duramax but it’s not the original and isn’t paired with an Allison transmission. Very good engine from what I hear.
Like you, I would also wait. I love GM but look at their history when it comes to Diesel engines that were built without Isuzu’s help, not very good.
B Laquisha
a 60-40 joint venture between GM and Isuzu in Moraine, Ohio. The Duramax block and heads are poured at The Defiance GM Powertrain foundry in Defiance, Ohio
GM taking a 34% stake in Isuzu was seen in 1972
In 1998 General Motors and Isuzu formed DMAX, a joint venture to produce diesel engines. GM raised its stake in Isuzu to 49% the following year, effectively gaining control of the company
It will have the joint venture GM/Ford 10 speed auto trans behind it.
Yeah proven to have leaky injectors and limp mode Transmissions
The gm rep basically said "yea we think it'll make to to 150k but anything over that is on you" lol
ncurc 97 oil pump belt, you have to take the engine out for replacement. Weird design
Ncurc 97, I bet a boatload of these engine will be on GM! That belt at the back may not make that.
I.T. Intern Its not weird, just their way to get in your pocket.
I.T. Intern you don’t have to take the engine out. You unbolt and slide the transmission back and can access and replace the belt.
At least he is honest. Most would just bs and lead people to this crap motor
$60K for those tough trips to Walmart and Home Depot on the weekend.
Boone Docker Lol
That’s 90 percent of diesel owners.
@@JI-sg5uy Chances are Home Depot delivery is cheaper than a truck.
Hold up, does that mean that the regen cycle works by injecting fuel during exhaust strokes? Oil dilution springs up to mind. No wonder max oil change interval mentioned is 7,500 miles. Why not using a 7th injector?
Don't forget Ford did this on the first gen 6.4l Powerstroke's, it didn't work out to great for them as they would metal the oil seal on the turbo and then turn into a smoke machine. Ford used the back two injectors to push fuel out on the exhaust stroke for re-gen.
TdrSld Ford and Cummins still use in cylinder regeneration....
A 7th injector should be standard for dpf vehicles. Keep the oil clean!
Aluminum block & heads in a diesel? I listened to the engineer describe all the "gizmos" to do this , that, & the other thing. I predict this engine will be a "GMC ......garage mechanic's companion' ! I buy a truck for reliability, & I will accept lower fuel mileage, higher weight, & fewer computer controlled crap, in order to get it. I drove Ford trucks all my life (I am 80 yrs) & I bought ONE Power Joke. I traded it after 6 months, at a significant loss, to buy a new (97) Dodge 2500 with a Cummins 12 valve. It has 1.5 million miles on it & still runs fine. I replaced the water pump once, the "O" rings on the delivery valves, the bell crank on the AFC unit twice, (the ball stud on the throttle rod connection wore out), 2 alternators, & it is still running on the original lift pump (admittedly it needs to be changed now) the original injectors, & the original starter....(starter is showing signs of distress) It has been the most reliable engine I have ever owned. The rest of the truck has been relatively trouble free. Right front inner axle seal twice, both front steering universals three times, steering box replacement, clutch complete at nine hundred & some thousand miles ( I live in a rural area & use the clutch only to get moving & then throttle shift through the rest of the gears) * I bought a n aftermarket exhaust system & fuel plate from Banks engineering the first week after I bought the truck, & it is still in good shape, with no obvious exhaust leaks. I live in southern Alberta, where little or NO salt is used on our roads (big cities excepted), so I expect that owners of this new Silverado engine will never make a "million mile " club ! I am aware of a number of 12 valve trucks locally that have gone a million miles without any major issues. The new High pressure rail injection engines are a nightmare, with pumps, pressure regulators, injectors (piezo units break, pintles break) SCR units burn up , etc etc. I will drive my Dodge until either the truck or myself expire ( my guess is that I will go first !!). Interesting interview.
Awesome comments. Thanks for sharing your experience as I have a lot of faith in Cummins as well.
Brian Hind : Chevy guy here, would always have faith in a Cummins. It's what they put that amazing engine in that bothers me.
Transmissions and front ends come to mind
Edit, for those that maintain their vehicles properly (like this guy with his 97 12 valve) vehicle will usually so very well like in his case. I've got a 98 Silverado 7.4L with 320,000 on it and changed the original factory alternator and water pump last year. Oil changes every 5000, being attentive can make all the difference
The Duramax has had Aluminum cylinder heads since it came out
Sounds promising: stick it in a VW Bug and the rear chain won't be an issue to repair.
Have you guys considered an update on the lm2 refresh engine the LZ0? Great video and great opportunity to bring the engineer back.
At least they sound like they care about the product. That's a good sign.
They are regular hard working folks who care about what they do.
Eye opening information here. 150k miles is not long to recoup the added cost of the engine. If you drive alot then after 3 years you'll be paying a mechanic to rebuild it. Good to know! Thanks!
Not rebuild it, replace it.
I think the engine has great potential, the problem comes 8 months to two years down the road when the Criminal EPA/CARB Cartel says wait a minute and makes GM reflash the computers when they are in for service and the truck owners end up losing 3 mpg's plus acceleration loss.
For the price of the truck I would be highly disappointed if the engine didn't last any longer than 150k. Besides my current one owner has set the longevity bar pretty high for my next new truck. ✌✌
mr.18436572 any well engineered car today lasts 150k running as new. The true limit is about 300k. Pretty simple. For poorly engineered cars they run correctly to 75k and the die around 120k.
@@777jonesI wonder how much $$$$$ it'll cost to get a new truck to 300k.
Listening to this guy talked me out of buying a 3.0L Duramax.
Silverado Duramax diesel vs Nissan XD Cummings diesel.... which truck you think will give you longer life?
All things considered I will admit that putting the egr intake behind the particle filter will help keep the intake cleaner from carbon build-up.
looks like something that will need $10,000 worth of repairs in 200,000 miles
In other words it looks like a diesel then? 🤷♂️
@@jadosa29 maybe a shit diesel
The engine will need to be split from the transmission to service the oil pump drive belt at or before 150000 miles. What will that cost???
Imagine that labor cost when you’re going to have to replace the oil pump belt at 150k miles.
Gary Jameson ever had a manual trans? Did it need a clutch after 100k? 🤦♂️
Has anyone been looking into the opposed piston diesels? Seems like a really interesting concept, but I'm but a casual observer.
Help I’m getting a 2021 Denali. Order the Diesel or 6,2 then ? What is better ? I like the better mileage but I’m not towing anything. Which one is more reliable ? So many questions ... 😬🙄🤨
Where is the starter? Is it front mounted above and to the left of the crank? The exhaust and injector pump block conventional mounting in the rear.
Images in the background look better than what's available.
I really enjoyed driving this diesel Silverado. Probably more so than the Ford.
Was going to buy one but this isn't the first time I've heard this 150k miles comment. Never heard the reps do that before. I commute so that is three years for me, seeya!
What I’m concern about is the longevity of the transmission. I have a 2017 GMC Sierra crew cab SLT and the transmission is garbage.
Buuboi214 the new 10 speeds are nice. I have it in my 17 F150 and now have 55k miles and it’s never had an issue (unlike the 6 speed in my 2011). Ford and GM partnered together to build the 10 speed.
8 spd?
Rollin Easy yup!
@@Buuboi214 yeah I agree. At low/ parking lot speeds its garbage. Hard acceleration it shines
What going to happen with the water cooled intercooler when the truck is sitting or driven in very cold weather? What will happen if something cracks and leaks over the electrical system?
Still waiting for someone to ask this engineer if the 3.0 will be stuffed into the 2023 Colorado as an option.
Rear chain? These idiots...they design this stuff and then want to pay mechanics next to nothing
Yep. That's why I got out of auto repair. Very tired of being taken advantage of.
If they designed it from scratch why not drive the cam with gears as cummins does ? To simple & reliable?
@@robertmoulton2656 exactly! But a big part is to deter people from doing their own work...and at some point everything will have to go back to the dealer for repairs.
Robert Moulton Cummins doesn’t have overhead cams, does it. Might be part of the reason.
remove cab to service chain
The Car Wizard is going Rolex shopping.
I really like that they went with an in-line 6 but they lost me with a “wet” belt driving the oil pump at the rear of the engine where you have to separate the engine and transmission to get access to it. Additionally, an aluminum block on a diesel? No thanks.
Towing about 5,000lbs, mine uses about 5 gallons of def in 950 miles. That’s from Indiana to Tennessee and back. Loaded the entire time. Tows great, but uses more def while towing than what he said.
how fast were you driving? hilly roads? outside temp? fuel additive?
This assistant chief engineer just coined Chevy's new slogan.... "Nothing lasts forever".. From his mouth--not mine!!
well anything made by man can last from one second to 1000 years
anyone stating otherwise is either from another galaxy or they work for congress
Ya that's a given...nothing lasts forever that is obviously true with any manufacturer...we of course need to get over 300k out of any diesel engine...over 500 should be expected with routine maintenance
Curious what type of body mounted camera you were using for some segments of this video? I didn't see it.
I wish I could have one of these fine engines in a restored 1985 Buick Riviera or in a restored 1985 Oldsmobile 98 or even a 1985 GMC Vandura. I'd be in Hog Heaven
I'm considering using a 6.5 Turbo Diesel in my El Camino. Might even put a intercooler on it.
Oil Lease 6.5’s are junk. Get a Detroit or something if you can’t get a Cummins.
@@MrPland1992 6.5 s are fine, drove one many years and no problems except replaced the waste gate control with a Heath manual. My one ton got 18 mpg. It isn't as powerful as a Cummins but I don't feel the need to speed with a big trailer. It runs over 110 unloaded.
@@MrPland1992
The 6.5 is Detroit Diesel
So … 277hp and 460lbft of torque … I'm happy with the 420hp 460lbft 6.2L gas engine. I understand max torque is available at 1500rpm but would much rather hear 375hp and 550lbft or better on this diesel. Sounds like it's not good enough power-wise
Definitely designed for light duty towing. It's a shame Chevy didn't let us tow in the drive test. Ford let us tow with the Ranger, a mid-size truck as they were confident with the Ranger's tow performance - th-cam.com/video/RFUk16d7sHs/w-d-xo.html
732k on my 2011 Duramax.
Wow, nice! Do you do your maintenance?
@@4WDMagazine I do all my own maintenance. It's my money maker so I want it done right.
Bullshit put a video on your account and I’ll believe you
@@justinmartin8887 I'll be happy to shortly.
That’s more like it!
I can see all the engine bay space with a full delete
Good video but I won't buy one knowing that there is a wet-belt-driven oil pump that will be lucky to last 150k miles. Oil and heat do not favor rubber belts. And what is the shop time that GM allocates for the procedure to replace this wet-belt? (Hint: You have to drop the transmission.) I was looking forward to one of these diesels in a Tahoe/Yukon.
Swirl valves? That’ll be an issue if they have any issues with soot buildup
Low pressure EGR should result in significantly less soot being ingested... however I see they do use high pressure EGR during warmup so it could still become an issue over time.
I’m just speaking from experience dealing with sprinter vans in the rental fleet I maintain. Almost every one of them at some point had to have the engine pulled to get a new intake
@@RobertLeMay848 I can imagine... however the Sprinter uses high pressure EGR which causes tons of soot to go thru the intake, whereas with low pressure EGR the exhaust is drawn downstream from the DPF, thus the soot is already removed. So I would consider low pressure EGR the lesser of two evils as it keeps the engine oil much cleaner.
With VERY good preventive maintenance, a diesel should do 1M km or more.
Are there any plans to put the Duramax in the Surburban and Tahoe?
This is gonna be a sweet truck
good luck yeah in your dreams. Would have been different if they would have did a straight six setup like Cummings did for years but no..... we get this BS. Manufacturers are getting to where more and more reliable vehicles are becoming a thing of the past. Can’t make any money on repairs and selling you another vehicle if a truck lasts well after it’s paid off.
But how many recalls will it have?
I saw a guy with one of these trucks and he said he gets 39MPG something like 700 miles to a tank!
And he will get to pay 15,000 when the oil pump goes out and all bearings start spinning round and round then melt.
You can buy these engines out of salvage for 4k .. That would be silly to take that route.
Watch the video again at 7:20 he talks about regen. If you look back at the old way of regen(cleaning out the filter) gm in the LMM 07.5 to 10 Durimax had this system and ford had it in the 6.4 power stroke 08-10. When they inject the diesel into the cylinder on exhaust stroke it washes out the rings on that cylinder and will cause the engine to fail. Many as low as 20t miles. Almost all by the time it got to 150t. So I’m disappointed to see gm go back to an old system that they already know does not work and bring back a problem that they have already got an answer to.(adding an extra injector to the exhaust pipe after the turbo) very disappointing I was hoping to get one of these diesels when they come out but now that I have seen this I will be waiting till someone cracks the ecm so I can delete the dpf and egr before I spend my money on it. Or wait till gm adds the 7th injector to it.
Nice Cruiser driving around the ranch and the coffee shop I would not force this engine good luck
I like that they added it as a option for the LT, unlike Ford, VW and others. Only way to get TDi in the Jetta was to get a premium package which put the cost through the roof. Same with Ford. Someone who is buying a diesel engine wants economy, how the fuck do you think you will sell any of these when the vehicle costs as much as a house?? I dont care what the excuse is. I think Chevy did right here unlike the others by offering it in a lower trim. Only thing that really concerns me is two things right off. First, that bicycle chain sized single row timing chain. Not like we havent seen any failures from other engines with chains like this....Hemi... Second, how close that DPF is. Even if there are heat shields there, with that DPF up under the cowl next to the firewall, it will get hot and anything plastic there will be roasted in not much time. We'll see I guess. Looks cool though.
Does duramax 3.0L diesel can run with Euro 5 diesel ?
Any time some one comes up with a new wonder product it usually takes two more model years before it can be deemed safe for public consumption .
Wait until that masterpiece needs to be serviced..... you'll then experience what they call the "swirl" effect which describes what then happens to the contents of your wallet....SCRF means secures cash really fast.
Awesome - best comment today!
Unless these are built in the US from US spec parts (or German-Japan) this engine is going to be a anchor. Chinese spec/out of spec parts won't cut. Plus it sounds like there is ALOT of critical maintenance (dealer only) required.
So overall... more money to buy the pkge. More money to maintain the vehicle. And more visits to the dealer.
If your not driving over 20K miles a year. Get the gas engine and save yourself all the upfront-long term money and headaches.
"DAMN!" -mechanic
what would happen if you stopped adding blu def in the motor
Any one have any concerns about the all aluminum block,with cyl.liner issues? Past events..
is the truck frame wax-coated still?
Rob Grune .yes sir.
150k out of a diesel? Where is the 300k mile diesels....my gasser 6.0 made 260k before it started knocking and was pulling trailers right off the parking lot. Changed a water pump and alternator around 180k and that was it.
New trucks are junk regardless of brand, they know they don't make money making them last.
So, public math: 7500 miles on this diesel getting 33mpg, at $3.00 per gal plus $74 DEF is $755.82. So if your gas model gets 25.8 mpg at $2.60 a gallon, it’s equal. Then you can add in the extra maintenance costs and that the engine cost more to begin. This is at the current $0.40 gap of diesel and gas. It was at $0.60 recently. Hmmm
there are way to many things to fail and clog and two EGR systems they work so great with just one
Eric Herrmann This engine uses “cleaned” EGR, meaning it’s post-DPF exhaust that goes back in. No soot will make its way in. But that doesn’t mean Ash will not. After 100k, the ash will start to build up inside the DPF and most certainly some will be put back into the cylinders. If you’ve ever felt DPF ash between your fingers, you’ll know that it’s like pulverized rock. So, no, the EGR valve/cooler will not clog. But the engine oil will need to be changed at 3,000mi intervals -or less once truck is around 100k if you want this thing not to have scored cylinders by 150k. I really don’t understand the lust for more complex, more energy inefficient engine “technology”
Engineer said they started with a clean sheet in designing the 3.0. I was under the impression the Duramax 3.0 was the old Isuzu diesel. What gives?
150k miles with no problems my ass. Anyone who has ever worked on new cars/trucks knows that these new engines can barely go 20k miles without some sort of emissions or electronics issue. I'd be willing to bet that putting the DPF in the engine bay like that is going to cause failures because of how much heat gets generated from a regen. Also why is the timing chain on the back? This engine is going to be a nightmare to work on.
I bet a lot of things (like electrical) will go bad before the oil pump belt.
My Tacoma had a timing chain in the front and the cover leaked at 129K (common failure), still $3.3K to fix.
@@patmcbride9853 Exactly--virtually all timing chains in today's cars are a nightmare to work on. There is no room in most modern engine bays, and so much stuff has to be removed to get to it regardless of where it's located.
I just don't understand why GM is so tight lipped about the actual mpg. The reason to buy a diesel 1/2 ton is precisely mpg, depending on exactly what it is. I just took my 2019 with 6.2 and go 21 over 200 miles yesterday. To balance out the potential reliability issues with SCR, DPF, EGR, on the diesel, it had better get upwards of 30 mpg or it just doesn't make sense, unless you tow every day in which case say, 8-10 mpg towing with a gas motor will be considerably offset by 13-15 mpg with the diesel. I think GM is ultimately hurting potential sales by staying so tight lipped. People are getting tired of waiting and will buy something else if they are in the market.
I'm pretty sure they are just waiting for the 'official' numbers from the EPA, but seemed pretty confident it will be north of 30.
They use to be able to rebuild desil motors but not any more the blocks are throw always because of the sleeves but these motors do have more power.
I agree that it wouldn't be wise to by first year anything. But I hope that this engine will provide another way to reduce fuel consumption. Problem is, in my neck of the woods we pay 10-20 cents more per gallon of diesel. So it had better be VERY frugal.
Diesel is 40-50 cents more per gallon around here.
And there you go. What part of the country. I'm in So Cal.

Can I put a duramax ENGINE into the chevy D-Max??? (Isuzu)
Great engine so far. It’s too bad you can get a Chevy Silverado in a crew cab 8 foot bed like Ford and Toyota.
For the cost of this truck they better go 500,000 miles with no problems or they cant all hit the unemployment line.
Better get a good ol 7.3 PowerStroke or 5.9 Cummins 12v if you want half a million to a million miles. My 2000 F350 has 480something k miles on the engine without any major work.
You won't find longevity out of new vehicles today, they don't make money if you drive that many miles on one vehicle.
GM never said or implied the following: (It will make it 150k miles, that is 70,000 miles of power and greatness. I promise you will get the full 45k miles from this 15k mile engine and boy will it last you at least 150 miles. ). I went to a Chevy dealership and they swore the Durmax diesel had Platinum tipped spark plugs that would last 100,000 miles. I told them if the diesel had Platinum tipped spark plugs I would buy it right away. That sales guy was so happy until he talked to his manager when I ask him to verify they were indeed Platinum tipped spark plugs. Bought a Ram when the sales guy told me about the Cummins and knew all about including def usage rates compression ratios and laughed when I ask him if it had Platinum tipped spark plugs. He knew I was kidding.

omg you are right is deboss!.... what are they doing driving new trucks? xD
Rich tested both new diesels - keep your eyes peeled for the vids.
Ok. Cool engine. Glad to see GM making a light duty 3.0L for the 1500. However...however...who was smoking the weed when they decided to put the timing system at the back of the engine? Having to pull the trans to fix a timing chain is ridiculous. Better put a lifetime warranty on the timing system. I bet the stealership will be glad to ding you $2K to put timing components into this thing
I remember when automakers were trying to hit 100k miles....then they make engines last 300,400,500k.....and now back to 150?
I would have more concern with the DPF being right under the hood. Heat soaking the engine and intake air temps. Also burning out injectors with all the Cycling. Also seems like they maid the cooling system way over complicated. And two EGRs! Nothing but engine murderers.
You could be right. I think that's what limited the max towing number - cooling challenges.

Thanks for the input. Always great to get owner feedback!
Same on our Q5 TDI. Great motor
I've heard a lot of bad things about GMC. Do they make the trucks any better now?
Sherry Adams the old pre 2007 5.3 and 5.7 gm engines where top of the line, chassis and trans pretty decent. They went bankrupt shortly after that and got government bailout, since that they done nothing but build junk, screw taxpayers and keep their small excess funds offshore to avoid taxes themselves
Note that since this disposable little 3.0 diesel actually DOES meet emissions, you’ll be using 1.5 gallons of DEF per 1000 miles while towing. IF the 6.7 Powerstroke Actually met emissions (see Ford EPA diesel emissions settlement stories) you’d be using 2.5 gallons of DEF per 1000 miles while towing. I think the revised 2020’s DEF consumption will go way up to be where the emissions standards require them. Yikes!
Neo Craft
Funny you say that about the 6.7. My former service truck was a 6.7, upon delivery it had a code for NOX sensor...... After putting 32k miles on it I finally replaced it. In those 32k miles it burnt a whopping 2 gallons of DEF. 🤪😜😜. VW were just the only ones caught.........
I was excited about the superior architecture of the inline 6. So overcomplicated though. Non starter with removing the transmission to get to a belt. Gears can be used instead of belts/chains. Fuel rail pressures too high. I'll stick with the iron 4.9 l Ford gas. KISS engineering seems to be a lost art. Maybe they're designed to be in the shop often.
What about the 5.0 Cummins of the Nissan Titan 310 horse power and 555 torque the best
I believe it's only available in the Titan XD, which marketed as somewhere between and half-ton and 3/4 ton. It's also a 5.0L not a 3.0L. Because of those two criteria I didn't include it.
@@4WDMagazine why didn't you included is a half ton not a three quarters
It's so awesome that Nissan dropped it from the XD.

To me he didn't sound very confident about how long this engine will last kinda makes you think twice
I think Chevy's lawyers have told these guys and gals 'DON'T say anything!'
I agree - Cummins will be the only diesel for me.
Wouldn’t have a problem buying one of these.
They won't give an exact number due to legal reasons.
He's being told VERY CAREFULLY what to say by the company lawyers . . . even a 5 y.o can notice it. Liabilities and litigation are beautiful things . . . 🙄
Great engine until they used a belt to drive the oil pump. You just took a 500K mike engine into a 150K engine. That’s going to be at least a $1K service, and for me that’s about 7 years.
