- Here's a look under the hood and underneath the Jeep Grand Cherokee!
This 2023 Jeep Grand Cherokee features the 3.6L Pentastar V6 found in many other FCA products. Its paired with an 8 speed automatic transmission.
In this review, we take a detailed look at the engine and its sub-components, the transmission, drive-line, transfer case and its AWD setup, the new multi-link suspension and frame architecture, the cooling system, braking system, steering, fuel system and exhaust.
Overall the Jeep Grand Cherokee remains fairly basic from a mechanical perspective, with most maintenance items located within very easy reach (with the exception of the starter motor). The new suspension uses two lower control arms and an aluminum tubular welded sub-frame.
By reusing existing powertrains, Jeep has a reliable offering that not many capable SUV's can match in the market today, The power trains are dated and must soon be replaced by newer technology.

I love his sense of humor. He really is a good teacher of mechanics.
The FEM(front end module) comes from our Valeo plant. It’s the radiator , ecm , hoses and front end wire harness and some other parts assembled . It was funny seeing that rubber band . We use them to hold the hoses to the fem for delivery to the mack plant
More of these! I love reviews that focus on how cars work instead of glamorous shots of them going through mud or whatever
amazing review. you are a great teacher as well. the CV joint for independent suspension was a a great video too. I love your videos. about to watch them all.
Have been looking forward to the next mechanical review... thank you I'm sure it will be great!
Great content and completeness, as usual. Thanks for the effort.
"Soccer mum spec" should 100% be the official name of this level of trim
It sure is haha!!
so sad people prefer SUVs over mini vans b/c mini vans are so awesome....even if you only have two kids, it's so worth it as a people mover, furniture mover, everything!
@@charliep5139 yeah but mini vans handle like crap, look like crap, depreciate like crap. For the majority of needs, a station wagon would be just fine, but hey, gotta get an SUV because everybody's got one
Real reviews, thank you🙏🏽
Great review , I was thinking of getting one of these to replace the VW atlas cross sport we bought, .... but not anymore .
Impressive, and very interesting. You really run through every item quickly. I wonder if you teach other techs?
I own the previous gen GC, I'll watch that one next, thanks.
I don't teach techs. I'm just an engineer that's curious on how cars work 😊
This is awesome, extremely cool channel. Thanks, bro!
Best auto reviews on YT
This new Grand Cherokee is based on the Alfa Romeo Giorgio platform which would explain why it's so fancy! It would be interesting to see a Giulia or Stelvio on the channel as I guess they are pretty similar underneath (apart from not using the Pentastar V6 of course).
It sure is fancy compared to other midsize mainstream SUV's
Nice review..👍👍 Looks good, 🤞the simplified mechanicals will help in the long run..
It should with the engine. Suspension is more complex
Awesome review. You saved me.
Great info 👍
These are the kind of reviews we need.
This is, mechanically, an ok vehicle, but with a lot of deliberate obsolescence built in.
I have this vehicle, can u elaborate?
Sure, that's why they only last
250 300,000 mi before needing anything
Just bought one of these. Thanks for the tutorial! Boy, these things have gotten complicated.
Sadly, complicated for DIY to fix.
3:52 shots fired
Haha
I recently presented a maserati grecale on an elevator on my RUclips channel and both the grecale and the grand Cherokee are built on the Giorgio Platform, together with the alfa romeo stelvio and Giulia, but here i see they switched to a true 5 link rear design, the italians use a big double element arm that forms a single unit so it is technically a 4 link design.
That transfer case you filmed is 100% a Magna Powertrain Actimax system, the same as bmw x drive, alfa q4 and kia stinger awd.
It does not have a center diff, but contains a clutchpack with electromechanical camplate actuation.
They probably brand it as quadra trac I , higher spec models will use quadra trac II and quadra drive, which are all built by magna, because they bought new venture gear many years ago.
Former land rover discovery 4 models used something similar but with a true center diff and low range.
The new range rovers don't even have a center diff, they all use clutchpacks, probably magna too
Thanks for your feedback. This is the mommy version so yes the transfer case doesn't have low range it is loosely based on the stelvio platform but they changed a few things for the American market
More Italian junk yay!
@@foch3 italian cars are not junk
@@vladdutz20 From Motorcycles to cars, yes they make beautiful junk. My Jeep is 28 years and works and looks great. Can you sit here and say this will be as good in 28 years?
@@foch3 no but that’s a symptom of the time it was built.
Fins on the transmission pan serve two purposes: they do help with heat dissipation (a finned plastic pan will dissipate more heat than a flat plastic panel), and rigidity (the pan will resist warping).
Third purpose: Saves aluminum (sorry, plastic).
Thanks - I forgot about rigidity, you are right.
Another great video! Please do an Acura MDX Type S if you can.
That would be sweet!
Would you recommend one of these? I was considering this or a Honda passport, the jeep i found had better gas mileage and range with its I think 22 gallon tank but will it be reliable??
As A Young Man who loves cars for their Engineering & Design.
I Really Appreciate the Knowledge you Share about the Brain & Heart of These Automobiles.
You go str8 for the Throat & keep it simple.
Thanks. More coming tomorrow
Nice review maybe point out the axle disconnect system which makes it 2wd and 4wd automatically for the 1 speed transfer case systems it’s similar to awd till 25 mph it’s 4wd hi cool system for what it is old school with a new school
4:25 That front subframe is nice! It's like on a Lotus or Ferrari or something. It's nicer than the subframes on a lot of racing cars (e.g., TCR)... Good job Jeep! A quick Google suggests this new Grand Cherokee is based on the Alfa Romeo Giorgio platform (like the Alfa Romeo Giulia and Stelvio) which would explain why it's so "fancy", with the multi-link double wishbone, this extruded & welded subframe etc. 🙂
Thanks for this mechanical review! I love to see a new Jeep vehicle that's brand new with all the stickers on the parts!
Could you please do a 5.7 teardown? It's the engine I have in my 05 Grand Cherokee and I'd love to see what's inside with your presentation!
Great review, ,,,I come for the pointer.
Good video.....Does every car has dual feel pumps?
Thanks.
would love to see a mechanical review of the regular (non-Grand) Cherokee. I have a 2014 w/ 203k miles am am looking to replace it with a 2017 or maybe a 2019
Nice video
Thanks
I really like your channel, you explain very clearly and professionally, thanks.
Free Palestine!
@@fun_ghoul What is Palestine? I don't know such a country, there has never been such a country, who was the president or the king of this country? Check the history books dude
@@user-tx7tw9yc6m Your claim to Palestine rests on Judaism, but Judaism literally FORBIDS Hebrews from having a country until the coming of Mashiach. Also, Zionism was invented by atheist Germans, so...go back to Germany?
Thanks I'm glad you appreciate my work
@@fun_ghoul #EatPalestine
I absolutely love the subtle digs at the specs of this car : "grocery getter model" "soccer mom spec"
Good video. Why do we need to scan the car, every time we change the pads?
Thanks.
I absolutely love your mechanical reviews especially when you poit out obsolescence. I don't know if you take requests or suggestions but I would really like to see a mechanical review of 2020 or more recent to present year model of Toyota Tacoma. Please.
Would be nice if I could get a redesigned Tacoma 😃
Please do the 2018 plus Jeep Compass and Cherokee.
Love these videos, from Iraqi Kurdistan
Thanks from Canada
Thought it's US lol
I have a 2011 JGC, and I’m trying to understand why/when the Pentastar got so complicated. All that wiring and the huge amount of hoses up front look like a nightmare.
Overall I’m torn. I like the aluminum cradle, but not the overly complicated suspension. I like that it runs a timing chain, but not all the spaghetti hanging off the motor. Port injection is a huge plus.
Im fine with composite pans. Here in the rust belt steel pans need to be maintained.
I’d be interested in service intervals for all the fluids.
Good call. I've got a Pentastar from a Jeep Wrangler here that I'll be teardown soon so we'll see how that goes. I think the new JGC definitely has some improvements if you stick with the older engines. Not to say there are better choices on the market...
Notification squad!🔥🔥🔥
Thanks so much for subbing 😃
good video fOr someone who wants to do some work on their car, change oil etc.
Thanks 👍
U just give everyone a glimpse of your reflection 😆
plastic omnium, they make parts for our uk built corollas. seem to be heavily involved in all kinds of automotive plastics
Given how much detail you put in these reviews, how much time do you require to shoot a video. Are these showroom vehicles they give to you for test rides?
Once again awsome review thank you 👍 regarding your question I would pick 4Runner over this. I am not sure the suspension additions here actually do anything more . I can't trust to what I see under this truck...
15:24 that mounting to a piece of plastic might be for crash worthiness? They want the assembly to break there to have a more controlled sequence? The location is weird tough...
That's what I'd think. You'd want the engine and transmission to slide under the vehicle and not enter the cabin in a crash
Dude. Happy Thanksgiving, or whatever it is you guys celebrate up there in the great white, eh. Thank you for all your great content.
Why are you celebrating a genocide?
Thank you. Here it's called Black Friday Month. Lol
@sperdkar99 awesome review. I currently own a 22 grand Cherokee and I do feel the v6 underpower especially on hills. What's your thoughts on thr the turbo inline 6 for gbe wagoneer. I was thinking to upgrade
New technology will take time to improve. If reliability is concerned then stay away
@speedkar99 thanks for replying. What's your opinion on the wagoneer hemi v8 5.7 for the long run would it be reliable? Will it last to a 200k miles if properly maintained and good driving skills ? Because I'm in the market of buying one.
Thanks
How do you determine if the suspension fasteners are reusable?
I am debating on buying one of these. I get great incentives from working for the steel supplier and as much as I love my v8 trucks and traveling, I want something to replace my beater (2006 Ford freestyle cvt with 200k miles!) If my Ford can last that long, I's suspect these will be just fine.
I see more aluminum parts now because the previous version was heavy for what it is. Ther might be room for a twin-turbo I-6
I feel like the 2.0 T and i6 are next inline for the grand Cherokee
Pls can u do a video for normal v6 engin sound cuz i hear ticking sound on new 2022 jeep
such a crazy setup, but it's redeemed slightly because a lot of it is surprisingly accessible for replacing parts. not a cohesive build.
I'm curious as to what the deal is with all the braiding on the hoses in new cars these days. Say you need to replace a hose in the future - do you also need to reuse the same braiding, or does it absolutely need new braiding. Not sure what the points is beyond looking like a gaming PC.
I'd assume it'll include the braiding ...
Watching from Edmonton, AB Canada. Please do a super complex S Class or a Lamborghini
Whoa!!
Another marvel of modern technology and bad day for service technician. Brilliant location for oil filter. How many miles will it take to burn off what doesn't get sopped up with rag? Wonder how that plastic likes carb/brake cleaner sprayed on it to clean oil off or possible electrical connections buried in no man's land. Sorry for sarcasm forgot the reliability is unmatched. Great review, appreciate your efforts my friend!
Great presentation!
Welds on that aluminum subframe are just awful leaving huge gaps for corrosion and crud. Looks like it was made in someone's garage.
The silly finned plastic transmission pan looks like the weights guys weren't talking to the thermal management guys.
Yeah the welds aren't good. Wish they went with a hydroformed or bolt together unit
There's a lot of plastic!...
Thank you for the tour!
Another great review! Thanks!
This JGC, in my opinion, is definitely just an another piece of "S", good for perhaps a 3-year rental/lease at its best... no room in my garage.
Lease is a good option. Second owner will probably lift it and take it off road
I for one won't mind spending a little $$ to modify a used up 2023 Jeep GC just to see what will break 😂😂😂
Anyone know where to find the block heater and cord on these… he didn’t mention it.
If equipped, it's usually by the radiator tied up
I have a 2020 grand Cherokee so this one looks nicer than mine
I have a 2016 with the same engine and its much more easier to work on. The routing of hoses is very different. The suspension should be smoother, but more complicated compared to the wk2. The wk2 has been relatively good, so I hope the new WL is a step on the right direction.
Yes the platform is more complicated. Instead of changing platforms to the Stelvio platform, Jeep should have continued to refine/modernize the old MB GLE platform and bring back the turbo diesel 6.
I feel like they did this one good. Old school power trains, newer suspension and body structure... As long as everything is buttoned together and will last, it looks promising...compared to using a hybrid or turbo setup at least.
@@speedkar99 i believe that they will replace the extisting powertrains with a turbo I4 and a turbo (or twin turbo) I6 soon 😅
3.6 and 5.7 are the only good two engine FCA produces, but FCA product leak juices all the time, seals go bad too quickly, especially in Canada
Does that mean they can't cut the catalytic converter from underneath.
What are those hose for? Never seen so much hose in front of the drive belt lol
Cooling
Just waiting for them to put the Hurricane engine in these.
curious why you call a five link rear suspension italian
It’s a lot tighter under the hood compared to wk2. Jeep should have just used the engine from the Stelvio like how they are already using the platform 2.0l 4 with 280hp/306 Ib-ft (that’s more torque than the current GC) and use the new inline 6 for the 350+hp models.
I think those are the next engines inline for the grand Cherokee as we've already seen them replacing the ones in the wagoneer
Wow, the transmission oil filter/pan combo for the 2022 Grand Cherokee with the 3.6L V6 is $233.79 for a Mopar brand at RockAuto.
I went to the Jeep dealership for an oil change for my 2021 Grand Cherokee and found out that it's now $150.00. The manager cut me a break and only charged me $50.00 (she honored the birthday debit card which was given to me by the dealership). $150.00 for an oil change..Damn!
@@rahsaanthomas7030 I live here in very expensive SW FL and had oil changed at the Ft. Myers Galeana Jeep dealership 2 days ago. It was "only" $90. If I hadn't been there for the repair of the recall pinch bolt, I would have changed it myself. Oil change on this model is super easy!
How do you remember all that?
Wow. This was great to watch! I actually understand my car engine now lol
Do you like the older version WK2 or this version WL better?
The WK2 was a purpose built, no compromise, original design. No shortcomings or less than optimal design parameters were required to accommodate Internal Combustion, Hybrid, and All Electric in a single body on frame design.
Optimization of the engineering design is lacking in the WL.
Actually, it's the soccer mom models that have the air suspension. The soccer mom models have every bell and whistle (and good things).
Nice I miss the toothbrush and the videos bless and thanks.
You are welcome
When is speedkar going to start explaining ev’s with his toothbrush?
That would be cool. I'll wait for them to be more mainstream and available
@@speedkar99 why don’t you ask the audience if they have any to have you do a mechanical review on? Take a card out of Doug Demuro’s book.
LOL...how long is that plastic oil filter cover going to last in the hot V????
That oil filter/exchanger housing is a common failure on the 3.6
That's messed up - using your wife's and brother's good clothes: poor things...😲😉🤔 Great information and I am glad that I found your channel.
Thanks. And don't worry for them...
The only reason im actually considering getting one of this is because is the only SUV out there thats does not have a 4cyl o 6cyl turbocharged that its just gonna cause more problems later in life
True. Or you could have gone with a Nissan Armada 🙈
The weldings of the aluminium subframe look terrible.
They sure are visible 👀
3:52 🤣🤣🤣🤣 he's right on
Haha
I can’t believe they are still using plastic for the oil cooler housing. I just replaced mine. It will start to leak after at least 40k miles.
Soccer mom: 3.6L V6
Europe: 1.0L 3 cylinder
-_-
To add insult to injury most of them is naturally aspirated
@@hasanhariri8589 Yeah. :(
1.0 !! Can't imagine that
@@speedkar99 I mean, not in car like this, of course. In car like this, would be 1.5 or 1.6 turbo petrol or 2.0 diesel usually.
Just wait now until you will hear the rocker or lifter song .
Yes!! Very common on these
After almost 40 years jeep went back to passenger side drop front differential with the grand cherokee.
Was it always driver side?
Please do one on suzukis 😬
We don't have Suzuki here
Did he show where the alternator was and how (not) easy it is to reach?
Yes he said it was on the passenger side
@@NFLYoungBoy223 don't know how I missed that, thanks!
@@AndrewDasilvaPLT how reliable do you think this Jeep is?
@@NFLYoungBoy223 🤷🏻♀️🤷🏻♀️🤷🏻♀️
3.6 v6 rockarm ticking solved ？
I'm not up to date on these , what was the issue?
you forgot to put the oil dipstick back completely
Too bad
The front suspension looks expensive to maintain. Hopefully its later than sooner in your ownership.
Yes it will be since it has alot of links.
can you do a review on a 2018 jeep cherokee and a 2019 Honda Passport pleaseeeee?
Too old. Maybe if I find a new one
Great video boss!
J.ust
E.mpty
E.verything out of your
P.ockets
Haha good one
So the plastic transmission oil pan is protected by a sheet of cardboard... OMG
Will this ever stop?
I used to drive an LWB Land Rover in Algeria in the Sahara while working there. Everything was pretty solid but screwed together. That car was forever falling apart!
The cardboard is under the engine. The transmission is left open to air.
What's with the toothbrush ?
Review a Subaru's build quality pwease.
Good idea
Like all others its a 100000 mile throw away , the days of junk yard recoveries are over and what a great you tube channel great work. The commentary is fantastic really sounds prograde with proper annunciation. One question, are you prone to buying clothing for your relatives presents? You sure are burning through some their undies.
2021 Buick Envision (2nd Gen): any good or a hard pass.
Thoughts everyone?
Isn't that the one built in China?
@@speedkar99 Yes, it is.
15:16 Wtf??
Who engineers a crossbrace setup like that? 😂😂
Chrysler
It must have been a bet between engineers: How many different materials and mount points can you use for one brace…
LMAOO at the uncle jokes starting at the 12 minute mark...Santa Fe drivers really are something else ;)
They sure are.
Probably more Karen's in Santa Fe's thank in Cherokees
Seems like allot of hate going on for this vehicle. I test drove a Grand Cherokee Laredo which is my sweet spot. Jeep has 5k discounts even on the 24 model! So a 300hp 8 speed NA engine that is more capable than anything else 4 wheel drive. In my opinion looks better for 35 to 37k!! Everything you need nothing you dont... For example 17 inch wheels with the beefy sidewall looks the best on this vehicle. No Sunroof is a bonus. Very smoothe ride eliminating potholes and rough pavement. Would a similar Hyundai, Kia, be better? Certainly the warranty on those are but something about the Jeep Still maintainking its uniquely American Squared off STyle. I think this looks leagues better than than the Wk inside and out. I will be watching more long term reviews etc... I am also considering the Mazda cx50 which is the opposite as far as rougher more sporty ride.. Single guy here no kids or pets...... lol Also watch his and other reviews of other cars they all have issues, nothing is engineered perfect but these modern cars are more efficient, just as speedy if not more and safer than anything made 20 years ago for you old geezers holding on to junkers...
Reliability won't be it's strong point.
What year is this Jeep?
2023
👍👌
Thanks
