- In this video of jmcGarage Talk I take a closer, detailed look at GMs all new 2.5 Turbo I4 found underneath the hood of the 2024 Chevy Traverse. GMC Acadia, and Buick Enclave. #review #turbo #chevytraverse #gmcacadia #buickenclave #inline4
This engine is smooth, quiet, and powerful. It was designed for reliability using diesel engine technologies and specifications plus tested using the equivalent of a million miles in development. GM would not make such a strong commitment across their SUV and truck brands without doing the due diligence to mitigate failures. I have driven all popular 3 row SUV’s and bought the GMC Acadia Denali for the size and to get a light color interior. This thing is tight and as quiet or more so as anything out there today. In my case, I have a dealer quite close plus there are many GM dealers along the routes I travel most and this was a major factor in our decision.
This LK0 engine is going to be THE ONLY option for the ‘24 Chevy Traverse, ‘24 GMC Acadia, ‘25 Buick Enclave. I wish they would’ve stuck a turbo on a V6 instead.
GM must be confident in this LK0, sticking a brand new motor in 3 vehicles all in the same 12 month span 😮
Or they are planning on a lot of recalls.
I was all excited about driving the new Acadia and wow, what a disappointment. The vehicle itself looks nice and the interior is outstanding. The engine was pathetic and underpowered for a vehicle of this size. It also sounded like it was going to explode when I really stepped on the gas. The whiny and screeching from this thing was unreal. Sure, you can get it to move down the highway just fine, but the lack of acceleration off the mark was very disappointing. No way I would pay $60k for a something with a little four-banger turbo. I think GM really missed the mark here and I suspect that down the road we'll see lots of issues with this engine.
Why the big concern about spark plug maintenance? Change every 100k miles.
the 3.6 LGX in my 2021 Colorado requires intake manifold to be removed for 3 of the driver side plugs smh... Also using the engine coolant for the Water to air intercooler is IMO not as good, A separate one would cool better, but depends on boost I guess in this case.
My sister is in love with the new Acadia and could care less about a lot of the things we men care about regarding this 4 banger - my question is what’s your opinion on projected life expectancy and are there any aftermarket modifications that can improve performance that you’d recommend?
Keep after those oil changes and if possible add a catch can to help prolong the life anyway you can
2 cylinders and still only 21 mpg
Hello, I enjoyed the video. I am a subscriber waiting for the new Traverse to be released in Korea. I know that this engine is also used in the Traverse. After analyzing and driving this engine, do you recommend it? Do you not recommend it? Also, does it respond quickly and quickly when starting off? For example, sports mode
It's an ok engine but servicing the engine would be a bit of a challenge
All vehicles are harder to work on today. Have a 2013 Lincoln with an internal water pump.$2200 to repair.
that must be the 3.5 l engine....In Canada that would be a +$3000 repair bill....tis the reason I stayed away from the Explored/Edge that ran the 3.5L engine....I heard to eco boost is a total disaster.
Really surprised about the gas mileage. It’s as terrible as the 3.6 they had before.
You are not wrong
what did you expect, it's hauling a lot of weight
It doesn't have cylinder deactivation.
It's bigger brother which this engine is based heavily upon does and the head design between the two are nearly identical.
Probably in the 3500 too these days
Knowing GM and the direction they are heading towards it would not surprise me in the least bit
Pushing me away from these crossovers with such engines. What a let down. Was considering a 24 Traverse RS or 25 Explorer ST, but even the explorer has a horrible reputation…
really hope they put a diesel in it that 3.0 duramax is fantastic
Why are slapping turbos on everything? The original 2.5 Iron Duke got 30 MPG in a Chevy Celebrity back in the 80s. Never needed a turbo, and pulled those wagons with a quickness down the highway. Rode in one all the way to Arizona and back never had a problem.
It’s to make everyone happy at the sticker! It’s an easy way to get better gas numbers and power! Hints the mustang, Silverados, Toyotas, etc. little engines, better power numbers and mpg.. it’s just a big circle game
@@onsightwoodworks Right but here we are not really getting any of those things and we end up with an unreliable POS. I am old enough to remember when we did this before in the 80s Turbo Charge everything and it flopped because it beats up an engine, they don't last as long.
@@jeremypilot1015 Big difference is weight of the vehicle itself. Vehicles are much heavier than they used to be. I'm sure if you compared directly that old vehicle to this new one, you would feel a major difference in power. These engines are also built specifically to be turbocharged. It isn't the 80s anymore. Blocks and all internal parts are much stronger these days. You can easily make a reliable, turbocharged engine.
@@prestondeters5093 That is absolutely not true. I owned a 76 Cadillac Sedan De Ville that weighs more than a modern Silverado.
@@prestondeters5093speed limits is a factor too, 55 back then 85 now.
I've not read anywhere that this is Active Fuel Mgt system
That head design is heavily based on the 2.7 I4 which does have active fuel management
@@jmc6000can you reach out to GM?
How do you like the performance
It's OK but nothing to write home about.
Agree! But it’s not bad for a midsize truck! Coming from a hemi 6.7
@@jmc6000 did you use sport mode?
@Maxwell1989 I did and it felt close to the same as normal
@@jmc6000 well from the other reviewers they said once the sport mode is selected a really livens up and is ready to accelerate
Have you heard any failures/early issues come up with this engine?
None with the engine so far but the transmission on the other hand is a different story
@@jmc6000what’s the info on the transmission?
@Crraziee the new 8speed is been having some issues with failures happening early with leaking fluid is the 1st sign
@@jmc6000 ah that’s a bummer. Was looking at the Acadia vs pilot and others and I really wanted to like the Acadia. I’m not too fond of the pilot either in general but that engine has loads of space to work. Not a fan of cylinder deactivation though.
Where is the water pump located?
Outside in front of the engine driven off the serpentine belt
Thank you for this video, what an absolute disaster from a design point of view.
Engine looks like a big headache..
There is no substitute for displacement.
All cars are harder to work on now.
Deep dive but no output information? Come on buddy, throw us a bone on numbers, including towing capacity (5k). Also, no DOD/AFM for this, and the Buick model is the Enclave.
The 2.7 that it is heavily based does have afm unfortunately
What was the spec oil weight in this 2.5?
Full Synthetic 5w20
@@jmc6000 At least its not a 0w-something. Perhaps for spark plug change leave coolant hoses connected and disconnect TB and turbo ends. Might have enough movement to allow coils to come off. Is the plug change interval same as coolant?
I haven’t seen anywhere that says the 2.5l has cylinder deactivation. Even the EPA cert application says it doesn’t have cylinder deactivation or AFM.
If it does have it, I haven’t noticed it like I did on my ‘20 Blazer
The cylinder head is based off of the same design as the bigger 2.7 which does have cylinder deactivation
@@jmc6000 "based off of" doesn't mean identical though. With the abysmal gas mileage ratings this thing is getting, I'd be very surprised if it actually did have AFM. If it does...GM has a lot of work to do.
This engine is noisy and loud at idle and this is Not Good !! I’m unhappy with the noise
I have a 2024 RS
Unfortunately the price you pay for an engine only equipped with direct injection
Oh boy you give this engine 35,000 miles and watch the problems and going to be spendy
junk
Enclave? haha
The Enclave still has a V-6 as of now.
Horrifying!😧
