Overheated Chevy Cruze / Sonic 1.4 Turbo LUV Engine Teardown. Don't Drink Coolant, It'll Lock You Up

For part requests email us at [e-mail].
Today's Tiny Teardown, a 1.4L Turbocharged 4 cylinder from a Chevrolet Cruze. This LUV/LUJ Engine is found in the Cruze and the Sonic, and is notoriously unreliable. In this video, I tear this overheated engine completely down to find out how bad it really is.
This engine was supplied by Premier Automotive in East Alton, IL!
My name is Eric and I own and run a full service auto salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines. I don't build or rebuild engines, we simply supply hard parts to those that do!
Want to see a particular engine torn down? I may have already done one! No really, check out my other videos for the engine you'd like to see! I've made over 70 other teardowns from a Cummins to an LS7, and from Rotary to Ram Ecodiesels. You can expect a new teardown every week!
Check them out here • Blown Up Engine Tear D...
As always I appreciate all of the comments, feedback and even the criticism.
What will I tear apart next week? Just wait and see!

Absolutely love how the oil feed line wraps around the header before hitting the turbo, to insure the line overheats the oil and clogs.

[@david929190]

Probably done to heat the engine oil rapidly from cold because people jump in and go without warning up the engine and the engineers want things lubricated so they don't die early.

@Yeah Right As a matter of fact I used to clean my engines out by draining half the oil, adding 2 pints paraffin-kerosine and 2 pints water then driving 30 miles around town. Took out all the crap and left everything sparkling. You obviously didn't hear of the Ford no-oil driving test where the two cars ran 70 miles without oil.

@Yeah Right yeah and these days oil pumps build full pressure within a second with oils which will flow well even in freezing conditions.

Love the little 1.8 (H VIN) in my mother's Cruze. Thing has got the spirit, just not the guts. It does have an odd start issue with a metallic clanging noise (I think it is the starter, or maybe a defective flywheel) and a stuck thermostat. Also, the intake runner adjuster linkage problem, can't forget about that. I'm not even going to talk about the purge valve, that is just a GM car issue in general.

Having worked at a Chevy dealership, these engines and the 1.5 in the Malibu were our bread and butter. Cracked pistons, cracked turbos, failing water pumps, leaking oil coolers and so much more. It was almost a rush to greet the customer when a Cruze showed up. Repairs were good money when it was under warranty as well, techs were able to make loads of time on the warranty repairs, and when the customer had an extended warranty, it was even better. Though it always made me sad when someone rolled up with one and it wasn't under some kind of warranty, those were the customers that I really felt for since I know I wouldn't want to sink in 1-7k into a Cruze.

Let a 1.4 at normal operating temperature sit turned off for 5 minutes. Loosen the oil filter cap completely, but do not remove. Let it sit there while you drain the oil from the pan. Re-install oil pan plug, and now you can lift the oil filter cap and filter from the engine with no mess.😁 This applies to ALL all makes with a top of engine cartridge type oil filter.

[@Oddman1980]

This is what I used to do with the 2.2 engine in my Saturn Ion.

[@rosewhite---]

Simpler way is to drain the sump then run engine a couple of minutes without oil to pump it all out of the system. It won't hurt and engine to idle a couple of minutes without oil. Ford once did a test on two oils. Filled and ran the cars round a track at good speed. Drained the sumps completely then sent the cars out again. They both drove many miles until the one on the supposedly inferior oil seized up while the other kept on going until it was so sick it had to be shot. The oil companies have brainwashed drivers to believe masses oil oil is essential but in fact just remember all those old loco engineers who had to squirt a few drops of oil into the oiler of the crank pins and con rods before sending the beasts out to do some real work? Same goes for all those old drive pulleys and machines in old machine shops.

Just recently had my first major issue after 160k miles, needing a tow. One of the rubber coolant pipes burst while I was on the highway and sprayed coolant all over the engine bay and led to the engine overheating. Luckily it was a cheap fix and they had the part in stock at my local auto part dealer. It's been running great since.

[@HawkOnHOG]

I owned a 2014 Cruze, 2016 Malibu, and currently have a 2021 Trailblazer. I commute 50 miles to work, which turns to about 2500 miles a month with non-work related driving. About 95% of my driving is freeways. I change my oil at 7500 miles at the dealership, and get my 30k, 60k, etc heavy maintenance done religiously. I have had absolutely no performance issues with these vehicles. If my driving was more in-town, then I would change the oil at 3-5k, but because it's freeway driving, I extend it more. It's more about being cognizant of the type of driving you do, and keeping up on the maintenance to keep your vehicle in tip top shape. This can be said for pretty much every vehicle on the road, regardless of manufacturer or model. Great video, I love to see tear-downs of all scenarios. :)

[@zhbvenkhoReload]

Despite many turbo engines having design problems (companies trying to save money on the wrong places), I feel many of the problems could be avoided if people kept their oil cleaner and wouldn't wait on the drive thrus.

[@Wingnut353]

If turbo engines had proper idle bypasses that wouldn't be a problem.

[@alouisschafer7212]

5k Miles oil and Filter changes should be standard on any small turbocharged engine. Especially with the high fuel dilution from direct injection and questionable piston ring designs. Turbodiesels can probably handle longer intervals since they are lower RPM engines with less stress on the components usually. Ive seen eurodiesels run 25k miles without an oil change and nothing bad happened. Just more valvetrain noise and vibration compared to new oil. Other engines would not take that at all.

[@jayss10]

This….. Don’t listen to the damned oil life monitor. Change your oil every 5k with good synthetic oil. Oil is cheap.

I own one of these in my sonic 2018 and we love it but I do have to agree 100% with all the statements above we have always done oil every 5k adn should be mandatory but GM says to do it every 10k which is nuts to me on an engine that can run hot because of a turbo but I also hate to say it people tend to drive them like a race car because of it being a turbo car which is also stupid, the thing I find strange is this is the first I have ever heard of anyone not being happy with the 1.4 opel engine and around my parts no one has problems with them

[@alouisschafer7212]

@@johnflynn6140 100% on board with 5k oil changes. I change my oil every 6 months even if I have not yet reached 5k. My engine loves it. With fresh oil the lifters are more quiet and it seems to have less drag aka the engine revs smoother and there seems to be less engine braking while coasting indicating less friction in the engine. If you drive hard and do many wide open throttle pulls I would even recommend 3k mile oil changes.

[@ladin425]

I was working for a rental car company when these cars were new. To be honest, these cars were awesome to drive. The transmission tuning, engine noise, and the torque from the turbo engine really made it enjoyable to drive. The seating position was perfect too. Some cars did come into the shop with blown head gaskets but many cars took the abuse and were returned to chevy after the lease was over.

I love mine, only issues i have noticed is the turbo can sometimes loose boost pressure occasionally if driven for long periods of time, and it does develop minor coolant leaks easily. Not drinking coolant, but just leaks in plastic connector parts and what not, and there"s a coolant hose behind the engine that sits against a rather sharp spot on the block. It slowly wears a pin hole in the hose.

[@mike9rr]

Thanks for doing this one. A very thoughtful approach. As for your comment on air blockage at the front being a possible cause, that would be high on my list of suspects. I think some of these Cruz models had a feature that used some kind of movable vanes behind the grill to block air flow through to the radiator at highway speeds. The thinking was, I guess, that enough air would still pass through the radiator but from under the car. An aerodynamic advantage would then be gained as a result, at highway speeds, from air moving up over the hood in a more laminar flow. Then, at lower speeds, these vanes would rotate open again, parallel to air flow coming in, and more air would pass directly through the radiator.

[@myadhdSquirel]

Biggest issues with the 1.4t is the valve covers built-in pcv and the turbos crack around the waste gate valve.

[@kare9875]

What you explained was done on the eco models of the Cruze. This is done on hybrids to get better fuel economy. GM was hoping to get 40 miles per gallon on the highway and were quite pleased when they achieved 42. I bought the manual 2011 Cruze Eco March of 2011 and still have it. My sister loved my car and bought one the same year. We have been extremely happy with our cars. My sister had to replace her turbo last year and is now faced with the oil cooler failure. Mine has been fine. She has 55,000 more miles than I do. Knowing what we know now, we would buy them again. As I mentioned, ours have been basically trouble free considering their age.

[@DerPapierfliegernarr]

I've recently rebuilt one of these engines. Unfortunately, all the smaller GM engines have a similar problem in my experience: leaking timing case gaskets (although this one was the last shop's fault). The gasket starts leaking, water gets in the oil, and it overheats. Then usually the head (and in this case even the block) warps. And for some reason I have never seen any of these engines without piston skirt wear. If you can see the wear, it's usually already out of spec. But other than that, it's a decent little engine. A lot better than the 1l 3cyl ecotec

These are great engines, used in Vauxhall and Opels in Europe. I have rebuilt quite a few. The problems come from the drivers, not the engines. Most of these cars have a temp warning light and no gauge. The light comes on (usually due to a failed water pump) and people ignore it and run them till they stop. You almost always get away with a 5 thou skim of the head. A very strong engine and will take a lot of abuse.

[@southnyourmind]

That's not the truth at all. My wife stayed up to date with everything on her Cruze. Wouldn't drive it if a light was on, or if it needed something. So basically, she never drove it. No warning lights, but the water pump was leaking. Replaced it, and then had to have it replaced again. Then had to replace the turbo. and then had to replace the turbo again.

Very interesting video. I have a 2012 Sonic with 170K miles with this engine. I have had fairly good luck with this engine. It still runs well getting 40+ mpg on the hwy. There have been problems, but none of the serious ones you described here. For these engines to survive you must maintain them: changing the oil often and NEVER letting the cooling get low overheating the engine. I changed all the cooling hoses and parts after 80K miles/5 years and will do them again soon to ensure that the cooling system never fails. A few other comments: 1) The oil filter housing actually is quite good and easy to work on but does not "..puke[s] oil right down the front of the engine." In my view it is not too close to the exhaust to cause problems. 2) Sticking coil boots are a problem. Unless you were very careful and patient, you could almost never get the boots out whole. Originally, you could not buy the boots separately and you had to buy the entire coil pack ($100+) just to replace a $2 boot for a plug change. Now the boots alone are available aftermarket, As you would say: "ask me how i know." 3) From what I have heard, the oil system in the engine is pretty good. It seems that the cooling system is the real problem in that many problems are caused by overheating. 4) I am not sure it is ever worthwhile rebuilding these engines. It is pretty easy just to replace the whole engine so rebuilding just isn't a value proposition.

My sister had a 13 sonic and I had a 14 Cruze. I wound up working with ZZP performance just up the road here and doing some stuff to mine just to make my little econobox a little less boring. It was dialed up to 173whp on e85 with a flex fuel sensor added on to pull the boost down at 50% or less ethanol. I wouldn't call it fast but it most certainly was fun! With a new intake manifold eliminating the PCV failure spot, I had absolutely zero issues even running 21psi of boost with one of those Vermont Tuning enlarged turbos.

[@matth9275]

Engines aren't supposed to burn or use coolant. In 2013 I test drove a Cruz turbo, the Dodge Dart turbo, and the focus. The Cruz by far was the worst, no power and I hated the ergonomics. Space in the trunk was crap. The focus was OK, still a semi small trunk and tight in the back seats, power was OK but of course not turbo. It still seemed to have better power than the Cruz. The Dart was amazing. Plenty of power, handled like it was on rails, tons of room in the car and in the trunk. Amazing car, I traded my dart in 3 years ago on something else but I really liked that car. It had just hit 100k, was going to need timing belt, brakes, and tires and I didn't want to put all that into it. About 5 years ago I was at my buddies shop just shooting the bull and he had a cruz in there. Oil pan gasket was leaking, valve cover gasket was leaking, he said it had like 80k miles. He said they were absolute garbage, I told him about my test drive experience and he wasn't surprised.

Have one in a Buick Encore. Had to replace the valve cover twice (the EGR is built into it and you have to replace the whole thing). The intake manifold had to be replaced because the check valve for the exhaust gas gives up after about 100k miles - it is plastic, as is the water inlet and outlet with the thermostat housing. Had to replace these as well because the broke from the heat (plastic? Who’d have thought). The problem with the exhaust gas blow by eventually kills the catalytic converter which failed at about 150k miles. The replacement converter is not warrantable for this engine because of the problem with the exhaust gas circuit. You can tell when you have a problem with the EGR because it smells like a hamburger is cooking on top of the engine. Will never have another one, but my wife picked it out. .

I got one from PTP for my Malibu which has the same problems, cost like $150 and its kept my turbo going for 150k now. Took all of 10 minutes to install. Keeping the turbo from heat cycling so fast especially on short trips vastly reduces the rate that the wastegate housing will crack and in turn keeps the coolant and oil inside the turbo where it belongs. Basically, the itty bitty turbo is the achilles heel of this engine, the more stable it is the better.

1.4’s just leak coolant at the temp sensor at the coolant neck near the oil housing at 60k miles. It’s a known problem with neglecting oil changes(so all cruzes/sonics) probably just got ignored for too long and slowly cooked the head gasket.

Chevy Trax and Buick Encore also share this shitty engine

[@killerwowmaster]

Watching you take this thing apart was hilarious, you detached the cam gears from the head rather than ripping apart all the timing cover first which is exactly how GM says you're supposed to do it. They have you leave all that stuff in place and just pin the tensioner before you remove the head, its actually a pretty good design. That's why the timing cover gasket has a perforation where the head meets the block, so when you do a head job you can replace just the upper half of that gasket and silicone the corner.

[@javaguru7141]

This is worded really awkwardly. You're saying he didn't disassemble it the way GM intended, right?

[@killerwowmaster]

@@javaguru7141 No, GM tells you to pin the tensioner, pull the cam gears off, then pull the head. He started on the right path but why would you do it that way if you're parting out the engine anyway right?

[@steveblankenship5474]

I had a Chevy Cruz once. Coolant started to disappear with the car and I traded it in, watching this video made me more glad I got rid of it.

[@BITTYBOY121]

You forgot to turn this engine over by the crank bolt to see it its seized before you stripped it down ! - Great teardown as always man 👍👍

[@ChiefLink]

I've seen a ton of these engines come through a couple shops I've worked at in Texas. Primarily, they have overheated or developed coolant/oil leaks from the very filter housing you pointed out. Surprise surprise, putting a rubber gasket on a cooler/warmer block and then shoving it into the head behind the exhaust manifold means it fails prematurely. Similar to the 3.6L Pentastar from Chrysler, all that heat soaking is just too much for those seals. I've also seen a lot of these engines work just fine with proper maintenance, but the design is still questionable. Love the small engines, and there are a ton of interesting small engine designs out there! Keep finding them!

Where in Texas r u

[@iggynub]

Are there aftermarket remedies? ways of re-routing to avoid this? Forgive my ignorance.

[@ChiefLink]

@@iggynub Not that I know of. The cooler is attached to the block and the coolant lines going to it are steel. There may be minor variations depending on the engine, but that’s generally what I’ve seen. Particularly since the oil cooler is also the filter housing, engineering a better aftermarket solution is quite the task. The best one can do is address leaks quickly to avoid catastrophe, as far as I know.

I have a Sonic RS with the 1.4 Turbo. Tuned for an additional 40ish hp. Big difference. Put 100,000km on it with the tune. Engine was still mint. Sold it back to dealership cause I mucked the subframe on a piece of concrete that kicked up from a catch basin in a parking lot

[@texomajohn2916]

I have this engine in my Vanderhall , works well, great tune and other parts from BNR, pumping around 240 BHP

[@dps381]

I had a 2013 Cruze Eco manual and meticulously maintained it. I traded it in with about 100k miles 7 years later and the ONLY issue I had with it was the cooling system. Water pump leaks and cracked thermostat housing... Left me overheated and stranded on the side of the road more than once.

[@DxWhoopingCrane]

For some reason the Koreans(this is a Daewoo aka GM korea design engine) love plastic parts for the cooling system. Probably because they love economic efficiency over building top quality products

[@deviouslaw]

@@DxWhoopingCrane The cruzes are daewoos true but the engines are Opel designs. True world cars, kind of interesting all the different contributions from various parts of GM, even if they aren't the best vehicles.

[@brianr1899]

I currently have the same ride with 127,000. 5 water pumps, 2 coolant reservoirs, turbo oil feed line , oil pan gasket two times, throttle body, coolant return hose, and now I'm pretty sure my turbo is cracked. Leaks oil and eats antifreeze daily. Pretty much a engineering disaster compliments of GM. Only positives on that car is that it used to get 40 mpg all day long going 70mph and a really quiet ride. Never again will I buy a GM product after 50 years of their products. Thanks Mary

[@johncooley81]

@@brianr1899 I traded mine in for a Camry my Tahoe will be next.

[@jeremyscott6641]

@Cooley81 just had one as a rental while the cruze was being repaired after an accident, 5.6L per 100km and was a decent ride, I was always a domestic kind of guy but I will be looking at one for my next daily driver.

Have you done a teardown of a '14+ naturally aspirated mazda 2.5l? Would like to see the skyactiv tech. Exhaust manifold etc...

[@Theadventuresofyalc]

2.0 or 2.5 either of the skyactives would be cool.
