Today we are tearing down a core 1.6L Turbodiesel out of a 2018 Equinox. Yes, GM put this 2nd generation Cruze Diesel engine into the Equinox and the Terrain! They're fairly rare which is why I jumped on the chance to buy this engine for the video. This engine is a Fiat/GM Co-op, and has actually be available in most world markets for the last 10 years. It came to North America as the LH7, producing 137hp and 240ftlbs of torque. While I do know miles on this engine, 121K, I don't always get all of the details as to why an engine was replaced. We tear this engine down to try to piece together what happened, and what parts I can salvage from it.
Why am I doing this? My name is Eric and I own/run a full service auto recycling business called Importapart. Part of our model includes dismantling blown up and core engines and selling the good parts. We do not rebuild engines, merely sell parts to those who do. Every week you can find at least one new teardown on this channel.
I really hope you enjoyed this teardown. As always, I love all of the comments, feedback and even the criticism. Catch you on the next one!

Lost it at taking the spring clamp off then cutting the hose 😂😂
Paused the video right after he did that to see if I was the only one. 🤣
Ya! That one cracked me right up
That is the "book" method.
Me too! Like wtf😂🤦🏻♂️
It is best practice.
The tensioner plunger popping out and hitting the forklift driver had me laughing. 😂😂😂😂
I re-ran that part.
RIP WRX
@@blacksapphire256 It was already dead...
What he stabbed the forks into was pretty dam funny
@@georgeperkins4171 I have never skipped a video back as much as I did this one!
"It's nice the bolts are all the same size" -- words never uttered by a Ford engineer.
That forklift skit with the tensioner was probably the best one on the channel so far.
I hate seeing a sludge and/or varnish free engine that has failed. I feel like the owner kept up his end of the deal but the manufacturer did not.
💯
Maybe some overheating or pulling too much of a load? The sucked in oil filter still has me stumped.
seems like an egr failure for so long the intake eventually choked out the engine. with too much carbon in the intake, if it makes its way into the cylinders, the fine dust might end up wearing rings.
@@saeedhossain6099I agree.. Egr maintenance is key, oilchanges in line with mileage if driven to opr temp regularly. In europe we see the same thing, but more related to using diesels for many short trips, and not as intended. Dunno the fuel quality here, but it's decent but not great im sure.. A lot of HDI/PSA/Stel engines have been sold in europe to a lot of ppl, and as written above customers rarely used these as intended.
Probably because the oil was super diluted with diesel after numerous failed DPF regenerations.
I have worked on these engines. The timing chain issues with these are fixable with some ingenuity. In the Cruze the timing chain at the back makes sense. Very easy to replace the tensioner, which is the cause of the issues. The fix I came up with was to use the European Opel gasket that holds oil in the tensioner, along with the lower tensioner off a 3.0 Duramax, which is of identical dimensions but a better design, cast aluminum instead of pot metal. To replicate Opel's fix for this engine, also run the 0w-20 DexosD oil for the same 3.0 Duramax to get more oil flow to the tensioner in low pressure mode and on startup. Opel has their own version of the Dexos D spec for this engine in Europe.
Just drill out the passaged
That's good to know. Thanks for sharing!
0w20 in a diesel?!?! Now I've seen everything! That's crazy talk! What is the world coming to?? The end of the world is near! We'er all doomed!
Honestly I expected worse, that design seems pretty good compared to most rear chain design engines, other european manufacturers seem to like putting multiple tiny chains and tensioners back there. The chain seems fairly large but I guess it is let down by tensioner design but they thought of this and made the top cover separate so it could be changed without removing too much.
pennzoil ultra versions has way better lubricity and protection including high mileage..Project Farm has done a lot of tests un supported..oil is one thing but design is another and i quit mobil for ultra platinum for my diesel and Blackstone has verified my results...biodiesel need additives...
My Aunt has a Cruze diesel...50 mpg....250,000 miles(all highway) and so far no issues...she delivers blood from the blood bank in it to 5 regional hospitals...
What year ? The earlier model with the fiat engine?
Cylinder 4 glow plug looked like it was missing a piece as well as a matching little divet in the piston
YEP, caught the damaged glow plug.
Yup. Looks like part of it went on a suicide mission.
Small divot in the head too.
Scrolled down to see if anyone else saw this too
Noooo! I needed that WRX fuel door!
They can all die. Mine keeps getting stuck and I have a hard time filling up my car. Already had the dealership service it twice and finally replace the whole filler assembly, and it still gets stuck.
Cutting the hose after fighting the clamp brought me peace.
16:39 *Fore!* That was a good one! You almost took the forklift guys eye out!😂😂
Engineer Tony, "I want round intake ports!"
Engineer Giuseppe, "I want rectangle ports."
"Okay, half of each." The GM and Fiat co-mgmt team.
It's because one serves has a high-velocity swirl port (the one with the butterfly valve), so they were just optimized for different things.
It's not Fiat though, it's Opel. Same engine they put the the Opel Astra, I had a 2018 Cruze with the same engine. And the 2nd Gen hatchback Cruze was a rebadged Opel Astra. Sold in America and was actually the best fuel mileage engine available in the USA at 54 mpg.
@@myadhdSquirel Same combined mpg as the 9 speed, 1.6 liter gasoline version of the Cruze, and the gasoline version burned much less expensive fuel.
Oh what a mess of carbon, EGR no friend of engines, I have opened up Leyland 680 ci engines 20 years old, City Council work, more than a million miles, but they never looked like that.
@@timlee4204 No friend to DIESELS, gasoline engines do just fine with EGR. Diesels kill themselves with their own filth.
Eric is the first stand up comedian who uses automobile engines as a prop (I think?) 🤔😅
Gallagher used a car door in his skits back in the 70's and 80's.
But I do agree, no comedians have used a car engine as a prop.
U think 💬 diesel = better reliability... Nope Chevy/Fiat missed that memo
Cam Top
The tensioner skit was really good !
I love your subtle hatred for chain guides! 😂
How do you feel about his chain kink?
OOOOOHYEAH
Eric, what's with these plastic chunks all over the shop floor?
Eric: a good chain guide
Foam keeps the noise out but keeps the heat in! Brilliant!
"The first step to removing the lower timing cover is to remove the lower timing cover." What a wonderful sentence.🤣
Wish we had more small diesel cars available in the USA
So do I, but not with current DPF & DEF emissions junk. Look how filthy those intake ports were. 🤮
@@maxcactus7Gotta delete the epa junk first thing leaving the lot.
Agree but the EPA ruined the efficiency and reliability of diesel for all. Terrible. I feel as for truckers.
With many blaming Volkswagen's diesel-gate scandal for, ever fewer diesel cars when it was that serious of top executives imprisoned as a diesel out of an equinox was allegedly replaced over excessive timing chain slack as if the owner didn't want to pay a bill of mostly labor to pull the engine from the SUV to fix the slack in the timing chain.
Well I can add this to my "I didn't realize this engine was ever sold in the US" list
Me too, like a 1.6 diesel in America ? I thought he imported one from Europe just for content …
Gm and their Harvard MBA marketing team strikes again!!!
It was such an aborted sales run because of various factors. Opel (GM Europe) developed the engine and GM America had the plans to import it. The plans were certainly in place before VW Dieselgate, but GM slightly attempted to take advantage of that by selling Diesel engines to VW customers (and that didn't work). Right in the middle of it, GM sold Opel to PSA Groupe (French company) because they whined they lost money for 16 years straight, and then PSA made a profit in the first full year of ownership so you have to wonder how bad GM management was. Anyways, GM found themselves selling an engine they were likely buying under contract from a foreign supplier. The Cruze offered the 6MT and 9AT, but the 6MT was dropped after 2018 so any 2019 models were automatics only. The engine was paired to a 6AT in the SUVs because there were no fuel economy benefits from the 9AT and it was way more expensive. The Cruze ended production in March 2019 and the SUVs had the engine in 2019 models. Then GM put out two press releases within about 10 days of each other - the first one said 2020 model SUVs would be FWD only because I guess the AWD wasn't often paired with the Diesel engine, and then shortly after that a second press release said the Diesel engine was entirely canceled for 2020 models.
This engine is also the cousin/ancestor of the 3.0 inline-6 sold in GM pickups. The 1.6 liter version was sold in Europe (some models offered a twin-turbo with that) but then the engine architecture was quickly changed to be a 2.0 liter 4-cylinder and a 1.5 liter 3-cylinder (both shared the same bore and stroke). So, Opel helped GM develop the basic engine architecture for the 3.0 in GM pickups. They say none of the parts interchange... but when you look at the 3.0 engine and compare it to the 2.0 or 1.5, the bore and stroke measure the same mm each. It's also no coincidence that the 3.0 timing chain tensioner (a stronger, more robust part) bolts right up to any 1.5 or 2.0 Opel engine and bolts right up to the 1.6 engine sold in the USA as a better replacement part.
Thanks for my Saturday night entertainment Eric. Loved the tensioner bit with the fork lift driver. Lesson #1 of working at ImportAPart, NEVER EVER take your eyes off of Eric when he is working around a timing chain tensioner.
I lost it when he yelled "fore"
@@TransAm-Jack - That was pretty classic.
Yesterday I tore down an engine that failed in my car last year, just to see the extent of the damage. I found myself saying all the same phrases as you use in your videos. Called for Blue a few times, slow motion EEWWWW when I found oil/fuel/coolant mixture that I off course poked at, threw the perfectly fine timing chain guides to the floor, babied the damaged water pump out and when I took the head off I even said "malice in the combustion palace" before performing my own scientific test on all the cylinders, even the one that had only half a piston.
I've watched so many of your videos that it's been engraved to my brain that this is how it's supposed to be done.
This is the way
The timing chain tensioner... 🤣😆😆👌
It was one of the easiest teardowns of all the videos I've seen you do. It appeared that there was some thought put into it's design. Nice engine that way.
You were told it was "bad" because they didn't want to deal with it 🤣
We normally see a reason why an engine failed...we didn't see that on this one. The owner didn't clean the fuel system and didn't change the oil enough, but there was no real damage. There's no reason why that engine should be scrap right now. I don't get it.
Or, did it not make economical sense?
At a minimum, you're looking at pulling the engine, R&R the timing systems since you're in there, reassemble and reinstall.
An actual mechanic could give an idea of whether it would cost more, less or a wash.
@@deplorablelibertarian 120K on a small diesel with only minimal expected wear on those bearings sure seems like it was decently maintained. Not sure how you came to the conclusion that the fuel and oil were somehow not maintained...
It just needed a timing system replaced... And intake system dry ice blasted and it would run like new.
@@kmet2000 It had broken glow plug on one cylinder and both head and the piston on that cylinder had damage. Was that enough to scrap the engine? I don't know i am not an expert but the damage is there.
I actually raised my hand... I'm glad you counted it!
I have an 2018 terrain diesel with the same engine, the emissions and after treatment is deleted and it runs very clean on carbon, the fuel economy is north of 50 miles per gallon on the highway it beats the hybrids, i expect 250 000 miles or more from this engine.
250,000 at the very least! My 1.8L in my 2006 civic is almost to 400,000. I’d like atleast that from the baby diesel too
I think the ding in that one piston is from the glow plug. When you were showing the head the far left cylinder had the glow plug slightly smashed compared to the other cylinders
What a shame. Other than the chain, which would concern me as well, this is one of the best looking diesels I've seen you tear down in terms of condition. It looks like most of it is reusable.
I had two of these. A diesel Cruze then a gas Cruze with the newer 1.4. The newer 1.4 is WAY better than the old ones, but the diesel is actually tons of fun. A tune and such runs it into a hilarious little beast.
But the cost of diesel can be much higher than gasoline.
@@thx1138guyoften diesel is cheaper than gasoline depending where you are.
Trucking industry makes sure diesel WILL be available
Gas is just for those customers you got hooked
I feel the reason there’s so many of these engines available is that they aren’t bad at all and the rest of the car fails before they do. If I remember they are opel diesel engines.
Those threaded bosses for removing the upper timing gear cover were referred to on equipment in the Navy as "jacking bolts" as they jack the parts apart to break the seal. Reduces the necessity of screwing up mating surfaces with prying tools like "Old Blue".
not just in the navy.
Been watching the channel for a while and was wondering when we would get to an engine that was this difficult to figure what was wrong. Love the content. Appreciate the comedy.
Always look forward for I do cars, videos!!
My dad and I own a automotive shop. It’s really cool to be able to see the insides of late model engines. Usually we don’t have to go that far into the newer stuff.
There's nothing wrong with seeing you tear a party good engine, it is still a learning experience to see all the appropriate Parts together properly.
I still want to get a Miata with a standard transmission for my daughter when she turns 16 and has her driver's license. She's turning 10 this summer so I've got plenty of time.
This engine is the best candidate I have seen for the gear drive for the cam of any I have seen of late. Ford did this on WW2 tank engines. With the engineering and materials we have today, it would change the industry standard again. Oh, by the way, these were made of aluminum and were dual overhead cam. An 8 cylinder and a 12 cylinder. I think this is the best diesel design I have seen of late. Thank you for this insight.
The GAA V8?
Virtually every Diesel engine has timing gears. Only these POS small foreign diesels have chains. There is some issues with high speed gas engines and gear drives, this is because crankshaft harmonics get transferred to the valvetrain. This can cost power and cause valvetrain issues. Obviously this is only an issue at higher engine speeds say 6000-7000 rpm and up. I’ve seen significant power loss 8-10 HP on a typical 600hp small block, valve train harmonic issues, and the inevitable ignition timing scatter on distributor ignition systems with gear drives. Belt drives are the best way to go on high speed engines. However for your typical sub 4000 rpm engine like a diesel these issues do not exist. Gear drives worked great in Aircraft piston engines like the RR Merlin because these things redlined at 3000 rpm or so.
@@Losingsince Yup and the V12.
You counted my hand up
and mine
I stuck up my hand to late. Damn maybe next time.
Me as well!
Thank you, Eric, for showing us the insides of a good engine, someone will clean up the intake, fit a new timing chain (Oh yes, a water pump) and will have a good engine. I was surprised at how short the stroke was. Ted from down under
I had no idea the diesel was offered in anything else but the Cruze.
Yes and I own a 2018 Diesel Equinox with 64K miles. Fairly reliable but the emissions bs has been a few issues on this. I had to replace the particulate sensor twice (once under warranty) and the EGR cooler but the actual engine has been reliable. I do change the oil every 4,500-5,000 miles religiously and when the diesel filter is around 40% it is replaced. This engine is a good fit for the Equinox returning freeway mileage around 45-48 MPG when I went from Washington State to Iowa last year. What really surprised me was to see 5 and 6 year old cars already starting to rust as we don't have that here in Washington State on the west side of the mountains. Keeping ahead of the maintenance of this engine will probably .extend its life.
They're also available in the Malibu, and they're available with a 6speed manual or a 9 SPD automatic
@@mikeske9777 I bought a 2018 hatchback Cruze with the 1.6td and after owning it did I start researching it and reading that you got stuck into a forced Regen cycle that you couldn't shut the car off and had to keep driving or it could fail the Regen and put the car into limp mode, but what irritates me the most was the auto stop and ultimately why i traded it in for a Camaro V6 that cost less than the cruise.
Thats in Korea.
The Auto stop is easily defeated with a tune or shifting it into L9.
Oh, that's the French/Italian designed engine built by a German company in Spain!
I thought Schaeffer build this engines for GM
The engines are built in Hungary.
At Importapart you are never safe from chain tensioners getting fired off..... out in the yard, bathroom...jeeez..hazardous place sometimes hahahaha
Love the teardowns Eric!
17:10 timing chain guides hitting the floor gets me every time.
Usually I don't enjoy your little skits, but the sprung tensioner bit was great.
But, but those are like the best part...
@@jeffreyshepherd8488 come for the skits. Stay for the carnage.
"Usually I don't enjoy your little skits", not to be the normal snarky counter-commenter but, come on Francis....
So far, out of most of my YT channels Eric's occasional light humor is just right insofar as he doesn't go OTT trying to be a funny man and it helps lighten the mood when one has to contemplate how stupid some people have to be to penny pinch simple maint.
This Engine was also sold in EU with 160HP and a BiTurbo configuration in the Opel Astra
I love when you mention the good state of a part and then proceding to trow it away. It was hilarious how that chain guide blew into pieces.
Great video.
I didn't know that they made a Diesel engine for the Chevy Equinox.
I didn't know they put a diesel in a chevy cruze! And I'm in the parts business, heheh.
Also not a diesel expert, but have theory: Carbon from emissions system has entered combustion chamber and damaged the walls. Does not look excessive on this engine, but also cannot "see" extent of vertical strafing. Engine also looks very well maintained based on cleanliness and low wear on bearings, pistons, cam, etc.
Hi Eric. I miss you showing results from the parts washer, especially head/intakes like this one to see how the ports/valves clean up. Otherwise, don’t feel bad about producing a “boring” teardown. Each engine is unique and interesting regardless of the failure mode.
I've learned a lot from this teardown, don't mess with them!
It's Saturday for sure cause Eric has delivered another awesome video!
Spring clamp removal and fork lift attack, what's not to like!! Thank you, Eric!
Gracias Eric, es genial saber que podemos entrar en tu mundo por un rato y compartir tu trabajo, reírnos con tu sarcasmo y tus dad jokes, y sobretodo por tu paciencia y constancia con el canal durante años, saludos desde Argentina
Eric, I always look forward to your engine teardown videos, especially emissions diesels.
timing chain issues related to oil pump that was tuned for efficiency rather that pumping oil which meant the oil pressure assisted tensioner could not do its job properly.
16:37 LOL - you better bring that protective bucket back. Or not, made me laugh really hard.
The tensioner bit with the fork lift driver would make a great UA-cam Short!
I wouldn't try selling that oil pump without opening it up first. Those have little plastic guides inside that usually fail triggering error codes for the variable oil flow system
Always a pleasure to watch you work.
9:42 I'm the one that mentioned that padding on the other diesel Cruze video. And I agree "try to design it to be as reliable as possible". That was GM though, they come up with a baidaid for almost every problem. If they would have put the amount of engineering they did in creating bandaids to actually fixing the problem, the cars would have been much better. They built an entire new state of the art Trim Shop to build the second gen Cruze and I never thought that car was as good as the gen 1 Cruze. They relocated the battery from the engine compartment to the trunk on the 2nd gen Cruze and they were having "no start" issues, so instead of having the body shop fix the body stud the ground connected to in the trunk, they had a washer put on somewhere in trim and it was someone's responsability to check for that washer before the ground lug was secured. So instead of actually fixing the problem, they added an element to someone's job on the line when jobs were already overloaded.
You sir are never boring.
Love the constant content filled with awesome!
If Blue ever got lost, your shop would grind to a halt!
"Timing chain at the back, what's wrong with that?" - Audi, Ford 4 ltr V6,
All the commercial diesels started rear drive years back. Flywheel end suffers much less wind up and unwind cycling so gear drives, in this case the chain drive, should fare better. Other poor choices can undo this benefit.....?
And lack of maintenance on top of poor design that compounds the problem!
the Ford 4 liter V6 has two timing chains..front and back!
Designed for fitting East/West so engine out is no big deal, sez I, who worked on bus and coach engines with a little more elbow room. Ted from down under
@@adotintheshark4848 That was to save making a Left and Right head, both heads were the same. Ted from down under
That tension-er bit made my day - thanks 🤣🤣🤣
I have this engine in my 2018 Opel Astra St in the smaller 110PS variant attacht to a 6 speed manual . I bought it 2years ago with 70.000km right now it sits at 110.000km oilchance every 10-12.000 km. Tops out at 200km/h. Normal travelling speed is around 140 to 150. I get arount 850-900km out if a tank.
Thank you Eric!👍
Gotta love the cappin' the crack cams off.
And what comes after? Hopefully a loud popping of head bolts loosening.
I've seen one of these in and Equinox once. The car came in the shop due to the timing chain slapping and iirc it wasn't fixed and the car drove off.
Also there's a vacuum pump as part of that oil pump assembly. I've seen that on one of the new 3.6 V6 variants too.
I came for the breakdown and stayed for the show. Thanks for making it fun!
Wonderful laughter on a Sunday morning, why didn't you wear the recycling bin on your head this time? I appreciate the driver who had to take it on the chin, WELL DONE 👏
Yes, safety tote must have taken the day off todsy
My guess is that it failed a compression or leak down test. Between that and the loose chain, it was probably condemned. The vertical scratches in the bore are a huge question. Maybe a poorly placed air filter at some point that allowed some extra crud to get through and into the engine? It may also explain the single ding on the one piston. 120k is premature failure on a diesel. It otherwise looked like a well maintained engine.
I think the intake manifold and intake ports told the tale on this one. It was being starved of air because of the sludge/carbon buildup in the intake, causing it to run rough and/or be down on power. Rather than try to fix the engine, the owner elected to replace it.
As the ports were partially block wouldnt it be running rich? Direct injection still putting correct fuel amount in but less air can get in the cylinder.
@@deanbarton4441 you're correct - it would be starved of air. Direct injection bypasses the intake manifold. I corrected my comment.
Had to go back and watch that tensioner scene a couple of times 🤣
Besides the timing chain problem, I think I saw a blown glowplug which would explain the damage on one piston.
Thanks for this teardown. I haveca 2018 Chevy Equinox with this engine; my engine was made in Hungary! I only have about 54k miles on it, always swap oil (Valvoline synthetic) & filter (K&N or WIX) around 4k miles. Bought it because I could tow it behind my motorhome!
What a horrible horrible investment on your part. 😢
@@fastinradfordable Mine's still running just fine, and now I know what to look for. Most people don't change oil & filter nearly as often as I do.
Definitely enjoyed this teardown. Will probably be doing the timing chain soon on one that has less than 60k on it. Starting to get pretty noisy!
Cleanest as far as varnish I’ve ever seen on the channel so far………
I really enjoy the videos!
Thanks to the Timing Chain Tensioner Sniper! (If I worked with you I would need a suit of armor)
Great video. Thanks for sharing. Have a great weekend.
@i_Do_Cars You MUST clean the carbon off from the top of the cylinder before knocking out the pistons on a diesel!
The carbon is much tougher than on a gasoline engine and can easily damage the skirts and the graphite coating on the pistons.
The pistons also look really bad on this engine, diesels normally doesn't have carbon buildup past the first two compression rings, like gasoline engines pretty much always have.
Carbon not passing the compression rings also means that plugged up oil control rings is rare on diesels.
The cylinders also look pretty bad for the mileage, i personally haven't seen them that bad before.
Never boring!
Saw one of these a couple days ago. Thought it was pretty neat.
At 16:37
Best tensioner, Full Release, EVER! 😁😁😁😏
Thanks for the laughs! 👍
Mike in San Diego. 🌞🎸🚀🖖
Just a slight correction, this engine was not co developed with Fiat, this is a completely GM derived engine. The 1.6 multi jet is a rebored and restroked version of the 1.9L diesel you previously tore down which came earlier was a belt driven engine which has no major reliability issues.
11 minutes and 56 seconds before the star was brought on the show blue should always be in a place of prominence
RE: extra insulation under the hood and firewall for quieting - that was in the GEN1 Cruze with the 2.0 Diesel. Those cars came with extra insulation for noise control. The GEN2 Cruze was the same car whether gasoline or Diesel, because the "WhisperDiesel" engine had all the engineering changes done to it to quiet it down a bit. Still, on cold winter mornings, my car definitely rattles like a Diesel engine does.
ya iv been watching his videos for a long time now love them
Releasing that cam tensioner was classic!
I just learned about reading the top of the piston for “tuned” diesels, and when you showed the head the pattern looked the same.
You can't count that high, grin. But I count this as a great tear-down and Thank You!
I think the vertical scratches came from carbon that coats the intake.
Blue to the rescue!! 11:54
At the rate you are going you are ore will be a contender for the mechanic who has torn down the greatest number of deferent engines.
It's an Eco friendly Diesel! It keeps all the crud inside the engine intake ports!
Friend of mine in Rome has one. So far it's been ok. Pull up to a light, press the clutch and engine shuts down to save fuel. Release clutch and it starts.
So does my Toyota on a good day, as does Minis!
these videos are awesome , most car manufacturers have stopped making diesel car engines now .
34:30 "Probably a probability" - gold 👌
I’d love to see a tear down of the 1.4 in the gen 2 Cruze. Just to see how different they really are from the gen 1 Cruze. Keep up the great videos.
Grandpa's bar beats blue every time❤
I have the same engine in my vauxhall astra, its on over 180,000 miles now.
Only problem that i have had is that the flexi part of the exhaust manifold (that feeds the egr valve) split. This can be see in the early part of the video, when he is removing the turbo.
I do change my oil every 10k rather than 20k miles though.
I’m at 130K on my LH7 Cruze. Did the updated tensioner and gasket proactively at 100K. Hoping it lasts forever.
Did my first timing kit and tensioner gasket at 270k km, now with 296k Km when the oil reaches 10k it rattles a bit on morning startups after a very long/hot drive. All original GM parts. Everything else all original, even the accessories belt is still the original from 2014 and is great.
