JUNK Ford Ecosport 1.0L 3-Cylinder Ecoboost Teardown. LAWSUIT ENGINE!

Check out our website at www.Importapart.com or email us at [e-mail] for parts and part inquiries.
I've been tearing down engines on camera for 2 and a half years! Search my channel to see what I've torn down.
You have been asking and FINALLY! I found one of these little nuggets of combustion. A 1.0L, turbocharged, direct injected 3 cylinder Ecoboost from a Ford Ecosport. This is a pretty unique engine in design as there aren't a lot of 3 cylinder offerings in the US, and I think its the first domestic branded 3 cylinder since the Geo Metro of the 90's. This 1000cc powerhouse puts down 123hp and is available in the front wheel drive Ecosport and Ford Focus, although they are available in more cars for different markets. This particular core engine is thought to have around 70-80k miles on it which is very premature for an engine failure on a modern car. I tear this engine all the way down to try to figure out what happened, and why it failed.
Why on earth am I doing these teardowns? I own and run a full service auto salvage business in the Saint Louis area called Importapart. Part of our model is buying blown, core and unwanted engines and dismantling them to resell the good, usable parts. We do not rebuild engines, we merely supply parts to those who do.
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!

As a Ford Mechanic from Germany I service the 1.0 Ecoboost alot. First of all the 1.0 is extremly sensitive, service it well and don´t mistread it and it will run for a good while, but make one mistake, ( run without water/ put in the wrong oil/ abuse it when cold...) it will die on you garanteed. I have seen allot of Timingbelts and Oilpumpbelts like that because someone put the wrong engien oil in wich then started to degrade the Belts. Takes only a few weeks for this to happen with the wrong type of Oil. Also the Cranksshaft isn´t keyed so the belt can balance itself when you tension the new Timingbelt, because you need to lock the VVT units and the camshafts when changing the belt. That also means you need to take out the starter motor and put a Flywheel lock in so the Crankshaft can´t turn when you change the Belt. The New 1.0 Ecoboost now has a Timingchain, but for some UNBELIVABLY STUPID REASON (mostlikly money). The Oilpump is still Beltdriven. So you still need to tear the engine all 10 years or 200000KM/125000miles apart just to change one small belt. Facepalm!! Also the waterpump is now Driven by a Dry theeted Belt wich is Driven by the Camshaft end by Cylinder 3. YAY. Pls end me know.😥

[@mattpalmer6054]

As an ex warranty administrator for Ford here in the uk I can say we changed dozens of these engines under warranty. We were doing several a week! It’s a completely poorly designed engine with little robustness. We had them meticulously maintained and still failed. Ford technical told me they were stressed to the limit the minute they leave the production line and have no resistance to any faults like low coolant. In the end we didn’t even bother stripping them down. Just fit new ones. Must have cost Ford millions in warranty repairs. Same as the 2.0 litre eco blue diesel in the Transits. They have tarnished the Transits reputation.

As a Ford tech for a little over 2 years, this is the 6th time I've personally seen this happen, not including the rest of my shop. What we hear is either 1. The tensioner itself fails and there is no longer any oil pressure, or 2. The timing belt loses every single tooth (likely still tensioner failure) and becomes smooth and of course, no oil pressure. Most cars will keep driving like this until the "Low Oil Pressure" warning crops up, at which point we get it. There is no recall, but ford issued a TSB which directs to replace the long block and turbo. Which is why they are in such high demand. Obviously just a horrible engine design. Absolutely loved watching this one. I also hate that turbo vacuum line, and there's always one fuel injector connector that gives me hell. Great teardown!!

Actually... you'd be surprised. My aunt and uncle had (or maybe still have) an EcoSport and the engine was nothing but trouble from day one. It was taken care of but seemed to chew up a belt like this one did every 20k miles. I think it spent more time in the shop than it did their possession, but the transmission never went out. I hit the transmission lottery with my 2013 Fiesta.... for a while, at least. It went in for the recalls, and every once in a while it would shudder, but the TCM going out at 132k did it in back in 2021. After six months of waiting I bought a new car, and here we are almost two years later and it's still sitting on the lot, not fixed. A shame, because other than the TCM I never had an issue with the car at all. Ran great, got amazing gas mileage, and the only time it left me stranded were dry rotted tires from sitting before they went on my car. Wasn't obvious at the time of purchase, unfortunately.

This engine was designed to survive just long enough for the car to be out of warranty. Also, Ford hasn't keyed their timing components in at least a decade. It's all held in time via tension. They even make special tools to lock everything in place anytime you need to undo the crank pulley. Because that bolt is the only thing keeping the engine timed.

The older Mazda L engines(MZR 4 cylinders) also didn't have keyed cranks. This channel has 3 teardown videos for the turbocharged 2.3 engines and Eric wasn't happy any time he had to touch one. Mazda's own Skyactiv engines have changed the crank to have keys, but some of the Ford Ecoboost 4-cylinder engines are based on/have design influences from Mazda L engines, so they still lack crank keys.

[@msmeyersmd8]

I'm not an automotive design engineer. But I have worked on several models of older American engines. V-8s of course. Is there any other kind? OK. Straight 6s can be great. The lack of keyed belts still stuns me. Am I correct that the tensioner made of plastic, that had disintegrated, was all that kept the engine timed? Unbelievable. It must be a non-interference engine because there was no evidence of valve damage? American Ford V-8s could be be poorly designed. A 289 1966 Mustang used a cam gear with nylon coated teeth. The nylon would wear down and cause the incredibly strong metal timing belt to slip a tooth or two. Hopefully no more than that. Why? It made the engine quieter. And probably accelerated planned obsolescence for Ford.

I had to tear down my sons 2.5 L Ford, however, and was struck with what I thought was absurdity when I found that the crank pulley/harmonic balancer was not keyed. I've been found out that the location is determined by a crankshaft counterweight stop which is in the form of a threaded bolt, used specifically for when the engine is serviced in anyway that requires the disassociation of the valve train, and the crank. after putting the engine back together, I realized that this is a fairly straightforward and solid engineering principal. It's essentially the same thing to my understanding as the Miata engines, and about 1 trillion other small car engines over the past couple years! Again, thank you so much for a wonderful video.

Its actually bad even for cost cutting. To cut costs, they would have made a better engine by NOT having a fuel pump attached to the cam. And the chain design is the worst I've seen for , well ever. They could have used a single double link design and a crankshaft oil pump.

[@Daniel-OConnell]

There is a good reason for no keyway on the crankshaft sprocket. It is known as a fully floating sprocket and is a very common feature on most modern OHC engines. It allows for perfect valve timing using alignment tools rather than timing to the nearest tooth. It is almost obligitary on diesel engines due to tighter piston to valve clearance. It is extremely rare for the sprocket to slip, if fitted correctly using a new bolt with each use. The added benefit is that timing is unaffected if the cylinder head or block needs to be skimmed.

This engine is also used in the Fiesta, in 100, 125 & 140 hp. Despite being calld 'eco', the fuel consumption was only slightly better than the previous normally aspirated 1.4. The 1.4 was just an adequate engine, burnt a bit of oil, but will probably outlast all the ecoboosts. Here in Europe, no keyway is becoming more common. Like you, I think the main reason is cost, but the excuse given is that the timing is set using holding tools, then the bolt tightened, so the timing is more accurate than being fixed by a keyway. My brother left a breaker bar on his crank pulley (Peugeot 307 2.0 petrol), hit the starter, bar hit the chassis, undid the crank bolt, timing moved, valves bent. Oops!

I'm baffled by why this engine and car exist with such terrible fuel economy. The Toyota 5S-FE (2.2L I4) in the XV20 Camry was a basic NA engine with an ancient 4-speed (3+1) auto was rated 21/27mpg on the EPA cycle. Admittedly that standard has been updated but I personally saw 29-30mpg on long highway trips with the AC running. The Ecosport is about 300 pounds heavier and has more emissions criteria to meet but...how can it be 25 years newer and still be this bad?

[@chrislack7219]

These were initially introduced into the US market in the 2014 Fiesta. I have one sitting in front of my house with a dead motor with 83,xxx miles on it, which is toward the upper end of the life expectancy you can expect out of the 1.0 ecoboom. I believe most failures occur due to the cheap plastic Ford used in the cooling system getting brittle after a few years and cracking or even shearing off completely, dumping all coolant and causing very rapid catastrophic overheating. I read a post from someone claiming that their CHTS registered something like 2,100 degrees at the time of failure. The upside to the motor is that it actually puts out about 149hp when at full boost (~21psi) which the ecu's allow to occur in I believe 20 second intervals (plenty of time to be full throttle in most real world situations). Coupled with a 2,500lb car, in the Fiesta, and it actually makes for a fun go-kart like driving experience. It also can get very good gas mileage. We got 46mpg once on a trip with four people and luggage. My avg when driving the car for a full tank was usually 38-39. My wife's avg was more in the 31-34mpg range. One day I'll fix mine and then sell it immediately. Not a fan of planned obsolescence.

The 6-speed automatic on the other hand averages 37.. idk what happened there but no Honda from the 90's has such a negative jump up in the fuel economy. The reason they went with a wet timing belt design is for better noise and vibration isolation, it also lowers the emissions, fuel consuption and friction loss. PSA(=french automakergroup of Peugeot and Citroen do the same, now some Opel and even a Jeep model use these engines with PSAs design. The engine series is known as Puretech or specifically the 1.2 Turbo versions I'm talking about EB). I know for a fact that these Puretech engines struggle with short distance usage.

I remember when this engine first came out. I had recently stopped driving my 3 pot 1991 Geo Metro and thought the idea of a small car with a 3 cylinder and a manual was not so bad. Then I looked at that wet timing belt and the amount of power they were trying to get from a 1 liter (about 2.5x that of the Suzuki 1.0 in the Metro) and knew that it would be a bad idea. I bought a new 2015 Prius C instead and it's been a great transportation appliance (if a bit unlovable). In 8 years and 142,000 miles, all that has failed is the A/C compressor (under warranty) and the 12 volt battery. With the Fiesta/ Focus/ Ecosport, they had bad engines and even worse transmissions, as well as poor fuel economy. If you want a good small car, you buy a Toyota or a Honda.

They were neck and neck and the 2.0 didn't have a full car length by the end. I have driven both vehicles extensively and I can say this. Off the line the 1.0 has a lot of grunt and feels quicker. Around 55 mph you can feel more vibration from the 1.0 where the 2.0 is smooth. Even though my 2.0 is heavier with the awd system and doesn't have a turbo the two get almost identical mpg (within 1mpg). The 1.0 runs hot. When you shut down the car it buzzes (I assume electric water pump) for several minutes cooling itself down (my 2.0 doesn't). I had read about the failures prior to buying the 1.0 ecosport but the forums said it was due to a oil not compatible with wet belts and prolonged maintenance. I only use mobil 1 extended oil which is supposed to be compatible and I perform our maintenance regularly so took the risk and purchased the car. With the new recall on the 1.0 at least her vehicle is still low mileage (28K) so hopefully the solution comes before any issues but I also have the 6 year premium extended ford warranty on both just in case.

Hi Eric, great teardown, I've been curious as to the insides of the 1.0 Ecoboost and it's wet belt! I was one of the first to buy one in North America: I ordered a new 2015 Focus, 6-speed manual, a couple of months before that engine was added to the Focus plant in Michigan, based on the good reviews the engine was getting in Europe (this was in 2014, before the problems became known). I drove it daily here in Canada, summer and winter, and put 330,000km (a little over 200,000 miles) on it WITHOUT changing the timing belt or touching the engine in any way, other than regular oil changes and a set of spark plugs! I guess I was really lucky....I sold it in late 2021, as I was having some transmission issues...and by that time it was apparent that the belts were a ticking time bomb. I was getting rather nervous about the belt failing, and having read up on the belt replacement procedure (special tools required to align everything because of the unkeyed shafts) I decided to let her go. It served me well, although the fuel economy was good but not as great as I had hoped. I think the reason it lasted as long as it did was the fact I was driving highway, 77 miles to and from work, each way. I did run the heck out of it, though, you could rev those things up pretty high! I always said it wouldn't win a race, but it wouldn't get in anyone's way either. I think what really kills the belts (other than having a belt run in hot oil in the first place) is city driving, the 240 degree power pulses of a 3-cylinder at low revs must put a lot of stretch-and-release tension on them, no wonder the teeth shear off! I miss the ease of service of my 1993 Escort from years ago, I could change the timing belt in 45 minutes in my driveway...no such cars nowadays. :-) Keep up the great work!

I had a 2014 Fiesta with the 1.0T. Started exhibiting head gasket failure symptoms (cold start misfire, no heat due to air in cooling system) around 40K miles on it. Ford put a new engine in it under warranty and I sold it not long afterward. Having seen this teardown, I’m glad I did. Their paperwork said “cracked block” - assume they meant cracked head. It was amazing on fuel, torquey, and sounded neat - neat enough to get my car/youtube video featured in a Jalopnik article on “cars that sound better than they ought to.”

[@johnsim3722]

No, they do mean cracked block! They cut a channel between the cylinders and that apparently cracks, giving the symptoms of a head failure whereas you really need a short block to fix the engine. Or a complete swap of everything.

[@UnknownJinX]

Regarding fuel economy, EPA rates 1.0T Focus worse on fuel compared to, say, a Mazda3 Skyactiv 2.0 from the same era while making LESS power. EcoSport was also rated worse on fuel than Mazda CX-3 or Honda HR-V, both with larger NA engines that make more or similar horsepower. Given the lack of displacement tax in North America and the issue with Ford Powershift, I'd love to know the reasoning of anyone who bought the car. This is why I am glad North America doesn't have displacement tax because then you get terrible engines like this. In a Fiesta or Fiat 500 I think it's fine, but in a Focus or EcoSport, the displacement is just too low and so you have to constantly rely on boost, which destroys fuel economy(engine has to run extra rich to prevent knock) and engine longevity. If you have to have a tax, base it on fuel consumption or emissions, not displacement.

[@gvicj05]

If a turbo engine is not on boost it is inefficient equalling WORSE fuel economy due to lower compression to allow for the increased cranking pressure of the extra air blown in due to the turbo.

[@johnsim3722]

@@gvicj05 I'd say it's a bit more complicated. My Subaru on boost was thirsty, keeping it off was more efficient but less fun. My direct injection 330i was very efficient, unbelievably efficient. So much so that my 1.5l Ecoboost couldn't match it and you needed it in boost all the time because there was no power without it, and would leave you limping out of junctions dangerously. My current 320i does have turbos and you can hardly tell it's a boosted engine, and is even more efficient due to the direct injection. I'd say direct injection is the key to an efficient engine, turbo or not.

[@soulsweeper1630]

@@johnsim3722e said that an engine with a turbo not in boost will be less fuel efficient than that same engine without a turbo, which is true due to parasitic drag.

I currently have a 60k 2018 Fiesta with that Ecoboost engine and honestly I've found it's okay compared to various other engines I've experienced. You may find it hilariously small but in Europe it's a more "sensible" size. I would suggest that the overall failure of that engine you have there is belt degradation which secondarily blocked the oil pickup for a lack of oil pressure. This is a known thing here, you have to religiously use the correct oil for that belt, a Castrol/Ford recipe based on 5W20 and nothing else. If the oil pressure light comes on, you stop and call for a tow, do not attempt to drive home. Thanks for doing a ecoboost!

I have that engine in my 2013 Ford Focus hatchback, achieved 90 000 miles before replacing the timing belt and the coolant hose (prone to fail on MK3 Ford Focus), engine is still running fine. I'm getting an average of 45 up to 50 MPG (US) on an everyday use. From now it is an "ok" experience, i'm always taking a look under the hood every two weeks or before/after a long trip because I know that a few things can fail with this engine (that's how I found the coolant hose failure) I bear in mind that this engine will fail sooner or later but for now it's really economical to run with the fuel price increase in EU. Bought it used for 5000$, I know that I can sell it for parts for almost 3500$, if it fails it will not be a big loss of money with the money that I did not had to spend on fuel on another car that uses more gas. This engine is basically "cheap to run if it does not fail". Did not failed with me, hoping to get a few more miles from it before it breaks down or before selling it to someone else. It will be a miracle if I can reach 125 000 miles with it. Ford messed up with this engine but for my first car this thing was pretty economical. Already seen some Mercs, Audis and BMWs fail before reaching 90 000 miles because they are poorly maintained, I would say that this engine is doing ok when it's well maintained with the proper oil recommended by Ford.

What do you do with all of the bolts you remove? It seems like there would be a market/need for that, all be it small?

[@cmprodutions]

He answered this question once before. The cost of sorting and storing all the bolts makes it not worth it for most bolts. Not to mention a lot of cars use torque to yield bolts that have to be replaced once removed.

[@B1GDaddyFatStax]

You're actually right about how common the failure is and exactly why. I've only worked at our small dealership for about 10 months and have seen at least a dozen of these. It's always the oil pump/balancer belt failure. It starves the rotating assembly and literally self destructs. That includes destroying the turbo. Just a terrible design. The worst part is, we had more economical 3cyl engines back in the 80's and 90's that lasted longer. They just didn't have the power. Most ranging from 55-70hp. With stricter emissions and safety standards, the cars themselves got bigger while the tech lagged behind on 3cyl performance. So, they were phased out until the Smart-For-Two came along and piqued the public interest. At any rate, this is an example of over-engineering, and in all the wrong ways.

[@nerd1000ify]

Supposedly the wet belts create 30% less friction than equivalent chains. I can believe that, but given that a good chain drive is already like 98% efficient the total gains can't be much.

[@dalenmonroe6526]

@@nerd1000ify it makes sense when they're not wet drive like this and can be replaced easily, but now you gotta tear into the entire engine to remove them from a lubricated block to replace something that last almost the same amount of time lubricated with oil than when exposed to ambient temperatures

[@MadMarky]

Belt failure isn't caused by the tensioner though. Few people seem to realize that for wet belts you need to use a very specific kind of oil that does not have any solvents in it. Apparently this car got regular engine oil after a service. Just look at how badly the timing belt is deteriorated at 10:03

[@dustinlang4327]

I have an 18 Focus with one of these engines. Typically see 44-48 MPG on it with the 6 speed manual. From all I've heard and seen, the first few years had bad rubber/plastic for the cooling system externally leading to more overheating issues, but all years share those little coolant passages between the cylinders. Later 1.5L 3cyl ecoboost have a small passage drilled a bit deeper so coolant isn't touching the head gasket. Additionally, the belts are meant to be maintenance items at 150k miles, though I'm not sure how realistic that is with 7.5k mile oil change intervals, so I change mine every 4-5k. Every time I have seen this failure, the same symptoms happen, making it hard to know the cause, but effectively the oil pump locks up and sheers the teeth off the belt. Given both belts have continuous oiling from the oil pan by being dipped in, it seems like junk gets in the oil pickup and stops the flow. Whether that is sludge from long intervals or bits of the belt cracking off as gas and carbon get into the oil is hard to say and know as it kinda all looks the same when it is small. The belt is materially designed to not decay from being in oil, but I don't know what amounts of gas might do to it. That said, I think the most important thing is checking oil level (should be cooler oil then) and condition. I saw plenty of Equinox have stretched timing chains and is was anywhere from 60-120k miles, a shorter interval than these belts for replacement (while timing belts for GM were 100k and chains started becoming 150k on the newer Colorado's timing chain). Though I figured you'd have to take the head off to get these belts off... there goes my idea of an almost engine rebuild and check at 150k miles. I was hoping it would be like the GM V-8 with AFM where you see almost no head gasket failures in them... because you see lifter issues and the head gaskets are replaced when you do lifters. In my ~4 years at GM I saw a LS head gasket failing once, but lifters hundreds of times. Was ~$3.5k if it was just lifters, $5.5k if the cam was bad and ~8k for a new engine installed. I'm interested to see how my 1.0 does compared to my 302.

[@tomislavkralj8767]

This engine is another example that the primary goal of the auto industry is to take as much money as possible. When such a breakdown occurs on the engine, most people decide to buy a new or another car because the repair is extremely expensive. It most often happens when the warranty expires. The timing belt is perfect, quiet, safe up to 90-120 t/km and its replacement is relatively cheap compared to, for example, changing the chain on an Opel Astra 1.6 cdti. But on that same Astra, when it stretched, the chain started banging and people still noticed (those who occasionally listen to their car) and still went to the service center and prevented the engine from breaking down. That's why the engineers decided to put an end to it and decided to install a wet timing belt so that the engine is quiet, so that you can't look at it in the service center and assess whether it needs to be replaced. And that it breaks just when the warranty expires. And this is not only a problem with Ford, all manufacturers do this. The Japanese are no longer what they used to be, neither Mercedes nor any other.

[@surferdude4487]

My Dad had a 1971 Ford Ranch Wagon with a 351 Windsor engine under the hood. it blew up at 40k miles. When we tor it down, we found nylon teeth from the timing gears jammed in the oil pump.

Here in Brazil, we've been dealing with those three cylinders engines, wich push the Ford Ka vehicle since 2014. We've regularly been dealing with that timing belt failure you've faced, when the timing belt loses its teeth. It's been caused when owners use not specified oil for a long time and timing belt starts to lose teeth or releasing material, wich block the oil pump. That engine has another serious problem I've faced so many times: in some cases, the engine is running with no oil or with low oil pressure and there's no oil indicator blinking. When you finally realizes the engine has lubrication problem, the engine is destroyed. 🤦🏾🤦🏾
