Lets discuss the 1.0 Ford ecoboost engine 

Had both belts changed at 10 years old 50k miles, only main dealer would do the job, two and half day job, £1,400. Factor this in if you buy a used one.

My mate runs a garage and it depresses me when he tells me about the faults in modern vehicles. Anyone would think manufacturers didn't want them to last.

I have a 1 litre ecoboost Fiesta 2013 152350 miles Belt changed at 150000 Belt showed little wear I have serviced it myself in my 5 years of ownership never let me down fantastic car. Look after it and will look after you. Last 8 cars all Ford all high mileage never had any trouble.

Ford designer: hey, I've got a great idea. Let's build a sub-motorcycle size engine for a family saloon car. Even better, we can design it so the rubber bands driving critical parts are continually soaked in oil; hot oil when it's running, but don't worry about that - think of the money we can make from scheduled rubber band replacements...

Had ford used a dry belt or a chain from the beginning it would probably be considered one of the best engines in car production today , well done ford , you messed up big style .

I have a 2013 fiesta ecoboost, and had a belt tensioner go, and damaged 2 exhaust valves on pot 1 & 2. Looking at the original tensioner the tensioner spring on it was held in place with plastic bars, and that’s what went and released the tension. I have rebuilt the top of the engine with new valves and belt kit, the new tensioner spring is held in place by metal thank god. As for the crank bolt I invested in a Milwaukee M18 Fuel ratchet with a nut busting torque of 1385 nm, I heated the bolt as I was replacing the crank seal, and it came out straight away no problem. For those who want to know the bolt has a torque of 720 nm!

Whomever approved the wet belt design should be flogged with wet belts for the rest of his life. In between floggings, he should have to spend his time replacing wet belts on these POS engines. This has to be in the top 10 of the most stupid design decisions ever made on a modern engine.

As an old guy who started working as a mechanic in the late 1960s I formed an opinion then which has only been reinforced over the years since, namely never touch a Ford with a barge pole. They've kept me in work many times but they were the pits way back then and if anything they've just got worse for a ton of reasons.

As this is the 10th year of the engine in a fiesta, and the belt replacement is 10 years or 150' 000 or 125'000 miles depending on who you talk to. I think people who know will want a cast iron guarantee that the belts (there is also the wet belt from the crank to the oil pump) or a £1'000 min off the asking price. We took our 2013 fiesta ecboost 125bhp to 108'000 miles with nothing other than annual oil and filter changes, 1 set of spark plugs and 1 pair of front lower wish bone arms,. But spending over £1000 on an " invisable" belt change on a £3000 car was to mad even for my man maths, so we part chopped and got a 3 pot 12'000 mile kia rio.

The idea of the wetbelt is that the oil is supposed to preserve the belt so you dont have to have it changed as much as usual, so you have the smoothness and cheapness of a belt but the reliability of a chain but weather this actually works or not is another thing. Ive seen it work for some people and dont forget a lot of these engines have been sold, so proportianlly they might not have as many issues, I think a big part of it is the right oil being used (ford spec 5w-20) at regular intervals to help the belt. Also engine flushes apparently wreak havock on the belt so dont do that but this may contribute to the issues as some dealers/mechanics/people may put the wrong oil in or flush the engine.

The older ecoboost engines had a problem with the cylinder head. There is a groove between pots 2 and 3 and this is a weak spot where gasket blows.

Remember the Ford 4.0 SOHC ? Engineering failures. Thanks for the video.

mine is at 95000km, a 2015 Ford Tourneo Eco. so now its getting 9 yrs old. commuted every workday 2*22km, very salty road in the winter, now the underside is very rusty! Engine seems still ok, did more than recommended oil-changes, always good synthetic as in handbook. I was a fan of VW until the management decided to build a 12_cyl for themselves! Then I changed to Fiat and now am proud of my Tourneo. Actually I bought the Ford quite by chance, when I was looking for a used car for my daughter. Used cars were all so old and high priced, suddenly I saw the Ford sales offer, changed my plans and bought it right away! Gave my Fiat Punto to my daughter; both cars still running. Didn't regret it; except that the 3_cyl is a bit rough starting uphill in snow! Once I couldn't get out of a snowy Garage, uphill, because the wheels were initially "rumbly" and car slipped sideways. With Ford's it isn't they build bad cars, but more that the mechanics, sales, and customers don't understand what Ford's engineers have designed! Lack of information/communication technical! Not really malicious intent; when I recognize THAT it is "over"! One critic to the engineers: if they had designed the oilywet belt in an O_shaped run it would last much longer! the X_shaped run causes much more bending of the rubber material. An O_shaped run could have lasted 400000km.

I saw you remove the front cover to get to the wet timing belt and I already hate that engine.

Vary informative, i would rather keep my 1.6 focus with 4 pots .Great engine along as you change the cambelt & auxiliary belts.

I inherited a Fiesta Eco boost off my mum 3.5 yrs ago. Full service history. I only do 3k miles per year in the countryside so mostly doing 60mph in 5th. It's been a dream to drive. Never missed a beat, and surpassed all expectations of a 1L engine. Today, it died as I was entering town. The power just went from the engine completely. I think it was still running but nothing from the accelerator. It then demanded a manual restart, but it wouldn't restart. There were no dodgy noises, nothing. My mechanic called me and has been vague about the cause, but says it's irreparable. It's only done 48,000 miles since 2013.

It''s a great little engine if you're hiring the car. Which I did a small handful of years ago, quite a lively little beast I thought!

I thought that sound was normal for this engine.That’s exactly how my one sounds.

I was told years ago by an old mechanic if your timing belt gets contaminated by oil, change it asap as it will eventually snap!! And that was on Vauxhall Victor engines which were non interference engines. I had one that lost its teeth on a bit of belt, about an 8" stretch of belt, that stopped the engine starting, but no other damage.

Hello good afternoon, just one question, do you think this problem with the belt bathed in oil has been resolved with the new Puma engines, where it now has a metallic chain, thank you

The one liter Ecoboost is now under recall but the parts aren’t available for another 6 months but they have new replacement engines that ford agreed to use

my favorite part is the fact they use a belt that notorasley fail my disintegrating when wet with oil then cloges the oil pickup.. i can only expect some one to come out with an aftermarket chain setup.

Just recently forked out £1400 to get both belts done, new plugs and a new VVT cam bolt. 90k miles so I thought it made sense. Car running well, hope to get another 90k as I really like my Fiesta. By the way, needed a new vacuum non return valve. Original broke up. New one £10 from internet. Easy to check, easy to fix. Screws up the boost when broken

I had the beginnings of a similar issue with my PSA puretech 1.2 which are known for the same wet belt disintegration. Fortunately I got rid before the engine grenaded itself. Ended up with a Mazda3 Skyactiv petrol which has been stupidly reliable over 3 years. The only issue I've had is the soul red paint peeling off on one side of the car due to a shoddy repair.

When i was looking for a replacement for my mk2 focus estate i considered a 1.0 ecoboist but reading all the horror stories i got a 2.0tdci 163 pug built engine well better

My 2015 titanium fiesta ecoboost suffered oil starvation due to the oil piclup strainer getting clogged with sediment from the wet belt.. Car had a full service history. If only they had used a chain this engine would have been brilliant.

My ecoboom overheated 2 weeks ago today. I serviced it twice a year. Only done 55k. Still sitting outside my house waiting to be fixed 😂😂

I have two, as long as the belts are changed 100k or before they are amazing engines. Will last even longer if you run a good grade gas or tune it for ethanol. No way I'm running 87 crap gas on a 20psi 10:1 compression engine.

Hit 130k on mine yesterday

How can this be an award winning engine? Who gave the award……..Ford!

Is a shame as is a great ideal I've got 110000 miles on mine and as of yet no problems and still running smooth fingers crossed.

How did this engine win so many awards? Exactly who said it was good when it has consistently failed with the same problem over and over?

Our 2014 ecoboost Focus estate engine hanging mount bolt under the battery, snapped. Luckily it happened while pulling away from our driveway? Needless to say the scenarios that could've ended in tragedy if this happened at speed doesn't bear thinking about???

Should be called eco boom . I had a 2014 with only 40 k on it and gearbox went . I had been planning selling it private as I'd of been ripped off trading in. Effing thing went on the day I picked up a Mazda cx5 . Now my Mazda playing up with engine problems . Some folk just dont have any luck . Mitsibushi l200 I bought for work , engine blew after 3 month .

The main thing those days you need to do with those turbo little engines is to do a oil serwis every 10kkm or faster. For the wet belt every oil serwis check/inspect the (i dont know whats the technical english word) oil suction gasket and clean it.

Whoever thought a wet belt was a good idea should've been sacked. The fact it got all the way through their processes before it was put into production speaks volumes.

Not sure what some people expect when they have 10 year old cars with ultra modern engines, if they’re not maintained correctly then they will fail. They should stick with older basic engine types especially if they plan to do their own maintenance. The eco boost is a compact efficient and powerful engine.

A truly disposable car, by the time the wet belt needs changing the car is worth 20% of what it was when new (because everyone knows about the belt problem) and the cost of replacing the belt, oil pump drive belt, idler pulleys, tensioner etc make it uneconomic to do.

It doesn't stack up too well to the previous normally aspirated 1.6 Sigma (Duratec SE) engine. Similar power output, similar fuel mileage much less reliable and much more complicated.

I had a ford fiesta 2018 with the same problem, my local garage told me its because i am not using the correct oil which was true. This engine problem mainly comes when the wrong oil is used which heats up the wet belt and makes it block the oil pump

Every Ford comes with the following two words COMMON FAULT

The wet belt idea scared me from the beginning, pure cheap skate, a chain would have been more suitable!

I always stayed clear of anything labelled "ECO" and as it seems my attitude saved me a lot of in my case not so hard earned money😂

Thanks for the info about the timing belt ! Just about to take delivery of a 2019 with 9000 miles Blue ST Line this week 👍

I’m not a mechanic but the concept of a wet belt hidden in the engine rather than a chain strikes me as poor design. If it goes wrong you know nothing till it really goes wrong. I bought a Fiesta for both kids and worry about this issue constantly. Would have been better with a well engineered Japanese car. It’s not so much wanting the cars to live forever, it’s the worry of kids being stranded. Disappointed with Ford, the cost saved can’t be worth the risk of catastrophic failure?

I’ve heard these engines don’t last that long due to the high piston speed of only three cylinders and small capacity?

Cool vid chap, all new to me this ...wet belt lol no way .....thanks

My wife’s 2003 Ford focus 1.6 ebony with 84.000 miles on the clock has now had 2 timing belts fitted on because of its age on because we don’t think the first garage change the water pump out which he changed use for and the pump went a couple of years ago so new belts fitted the last thing to going out wrong happened a few weeks ago was the power steering pressure switch blew out but was cheap to have fixed apart from a window regulator and brake parts the car runs great my car is the work horse been a diesel 1.6 2015 Astra j with 54.000 miles on it the I need a glow plug replaced which cost a lot because they have a pressure sensor on them It has a timing chain which is at the rear of the engine so hopefully it will last because it would cost a small future to replace

My wife has a 1 litre 136BHP Fiesta Vignale of 2018 vintage & I can't fault it except at very low revs, it needs to be spinning to move. We've had no mechanical problems with it whatsoever, however the Sync 3 has been a constant pain in the arse & we can't get any DAB channels at all.

I did a service on one of these and who thought it would be a good idea to put the oil filter where it is. It just makes a complete mess when you take the thing off.

Good vlog I have an ecoboost 1 litre automatic on a 68 plate I’m wondering 🤔 would it be worth someone making a replacement chain instead of the rubber belt specifically for this engine which would I assume last a lot longer and have permanent lubrication and no fragments coming off

When I changed the oil on our ecoboost engine I found tiny bits of red plastic in the old oil. Any guesses where the plastic comes from? The engine runs fine!

Not a bad idea but requires perfect maintenance

Ive got the 155 in a puma manual its an amazing engine and i will do regulat oil and belt service evry year it should do 250 000 if im lucky i had a focus 125 for 4 years not a problem

Replaced my belt just now, pain in the ass to do but no special tools required apart from the locking tools

I have a 2017 Ford Focus ST Line, which has the 1 litre ecoboost engine. My sump strainer got blocked as the wet belt disintegrated , starved the turbo of oil, here I sit £1,500 l8ghter.

The oil pump drive belt also sheds its rubber skin and dams up the oil pick up assembly. Replace both belts!

Darwin award winning engine. This Ain't Engineering, it's SABOTAGE! Turbo boosting a go-kart motor to do the job of a real engine twice it's size is asking for it at the best of times.

Great motor - best we’ve had.

MOST IMPORTANT ITEM FOR THIS ENGINE, DONT BELIEVE OIL CHANGE MILEAGE, CHANGE OIL MUCH MORE OFTEN

Had all of these problems on my car one after the other Ford replaced engine after cylinder head went due to pipe failure.then injectors went and had to be replaced I've also had 3 starter motors. Now the wet belt has gone after 25k miles!!!

I’ve had the ecoboost engine in two of my cars now 2014 focus and currently 2019 focus and have had no issues! But in saying that I do change the oil every six months my 2014 focus done 168k with absolutely no issues 🤷‍♂️I was told from the very start change the oil as often as you can because it protects the engine?

As you say, why on earth did they use a wet belt, probably an efficiency ecco design. I got quoted £1500 from Ford to change mine, they say most customers will get them changed early at 9years to preserve warranty.

Having had 64 plate now for 5 years done 80000 recently replaced new clutch and flywheel for a cost of £580 then to a new timing belt and oil pump for a cost of £980 which is a lot but finding someone willing to do it and do it well was difficult looking forward to hopefully a good few years of payment free stress free motoring cheap to run does the job mine has a st kit which makes it look a little nicer than the standard but who gives a shit I love my 1 PoP eco boost got some poke for a 1 litre also thinking lots of clutches and timing belts due to go bang if those have or looking at similar age vehicles

strange thing with these motors is that you get a lot of them that are fine at high mileage! We had a Ford Focus 1L for a pool car at a office i used to work at. it was a 2013 and had over 90k on the clock when i left in 2017. We did not take good care of that car and it was going as strong as the day we got it. it only had the one service a year! it can be pot luck!

I had one of these for 6 months, o2 sensor went, replaced under warranty, 2nd o2 sensor went had to pay to get that fixed, then the boot started to pop open when I was driving, had to lock myself in the car to stop it, eventually traded it in for a golf GTD….. I’ll never get another ford.

Im on my 2nd car with this engine. I had a Focus with 125bhp, and now i have a Puma with 155bhp. So far so good. The new car is very zippy.

Designed to not last. 'There is no Long term Replacement for Displacement,'

a new or nearly new focus is on my radar atm, but i just dont like the idea of 3-pots, even though i've never had one, and neither do i like the idea behind mhev, maybe i should look for an older model, as i last bought a new focus in 2003 and had it 15 years until i got rid, which i only did because after passing every MOT first time, never needing a new exhaust, belt, clutch etc, it was great, but it all came at once and was unviable to repair. I only do about 4-5k miles a year max so maybe it's a bit of a waste of money to spend around £20-£25k. any opinions welcome, but don't suggest electric please :)

Fantastic to drive but long term it's a lottery with these, Personally I'd never own a wet belt engine the whole concept make's the engine disposable as the vehicle ages.

Carmakers must keep there dealers happy. So don' t build a too good car. Many little repairs with little parts ( always very expensive in comparison for what it is) keeps your mechanics at work and the dealer in regular contact with the client who, might buy a new car when he is sick of jet an other repair.

I bought a 2016 1.0l Fiesta Titanium EcoBoost almost 2 years ago and even though i don't have any problems i do regret buying one. A cheaper little car with 100bhp under the bonnet and great econemy ratings, my mind of ignorance was sold. I might keep it for another 2 years then sell it. If not before.

thanks jim good video .😃

Small highly strung engines that have to constantly work hard just wont last. Imagine how hard that engine has to work whenever you drive up a steep hill or whenever you are on the motorway. Engines that do over 250k miles are usually six or eight cylinders. BMW's M57 3.0 turbo diesel engines can easily do 400k plus. Toyota's V6 petrol engines. Lexus V8 petrol engines. Honda J series V6 engines. Ford 5.0 Coyote V8. The idea is to have healthy mid range torque.

I have one with 100k on it. I changed my belt 12000mls ago and my belt was toothless on 15% of the belt - 1 tooth from skipping time and a miracle it didnt fail on me. I have done a lot of extra oil changes and more than most do. I have changed the hpfp and ppl have been saying it can also leak down through the plunger and cause a dillution. Is that a failure you have heard as its not mentioned? My belt should not have been so deterioated with the better service interval i've been doing - i have mostly done 5-8k oil changes - but a lot of ppl have been doing longer intervals than mine and had much less wear on the timingbelt..

I’ve had a 66 plate fiesta that has run faultlessly, I’ve just bought a 15 plate Titanium which is very low mileage and like new however I’ve had top up the coolant in the header tank a couple of times, I’m guessing it’s leaking from the water pump O’ring which is annoying to say the least

Are the 1.5 engines any better?

Built in faults..by design.

Very good information. Does the engine have to be removed to change the wet belt?

Sounds like a dreadfully engineered engine or an overly elaborate boat anchor

I have 2013 model, been standing for years now, cant get it to run.

My engine is loosing power when my rpm goes beyound 2000, ive changed the fuel fillter twice and also the fuel pump and the problem is still there, what might be causing that?

You do not mention the oil pump belt

Got 1 of these and its just under 10 years old with nearly 60k (owned since 3k). I'm in 2 minds if I should spend the money on a replacement wet belt. As in 10 years its been a good car for my needs. I've changed the oil twice yearly and filters, plugs at 35k. As for repairs, pads and discs (twice), tyres a number of times. Track rod end, lower control arm. Free on road tax currently.

I had a from new focus 1.0 eco boost 125 bhp. Without doubt the worst car that I’ve ever owned. Door seal came loose, headlight stopped working and required replacement, degas hose was replaced under warranty, both front springs broke and replaced, coolant leak from somewhere deep inside the engine, required the engine to be removed, at a cost of £1400 Ford covered this as a one-off good will gesture. It took two weeks to fix, one week to diagnose the issue. Coolant leak from the heater matrix, requiring the dashboard to be removed, at a cost of £1300 . The best thing that happened to that car was it getting written off in a crash. I will never buy another Ford car again, I have now changed to Vauxhall, Insignia 2.0 diesel estate, and now Mokka X 1.4 turbo.

The eco boost engine is a totally flawed design, even the latest version still has many problems, it’s just a ticking time bomb waiting to go boom

I’ll stick with my 20 year old Skoda Fabia VrSTDI PD. The body and electrics are a bit worn but the engine at 120k is just run in. The engines in today’s cars are crap reliability wise and this is one of the worse. It is a shame as it is a good engine when it works.

I have a half cut should I need to repair my car.

F.O.R.D……Fix Or Repair Daily. These wet belts seem to cause problems with all manufacturers!

My 23 Focus 1.0L gets 54mpg imp. Great performance but will do oil every 7-8k miles.

Please make a discussion about the 1,6 TDCi engine. Like to hear What you think about it

Bad idea full stop. Wet belt? Wtf? You won't see me buying one.

One more very big thing,The crank isn’t keyed making the engine time bomb.I don’t know why ford make at least two engines this way,eco boost 1.0 and 2.3 mzr engines. Crank not keyed

We have a 1.25 2016 Fiesta its smooth but gutless. The 1.0 engines are 'chinese style' it seems ie as cheap as possible in their construction. My daughter has the 1.1 TiVct engine which has been okay so far at 32K miles. But I am guessing its construction is the same as the 1.0 engine ??

Jim Farley: Let's NOT.....thanks.🥶

2018 ecosport 1l 125hp belt tensioner went, clogged up the sump following oil starvation. Looking at engine replacement for 5000€. Happened at 73.000km. Full service, but Ford won’t acknowledge their responsibility.

The Ford Puma 1.5l that and Hybrid model that uses a Chain timing inatead of wet belt has some over design improvements for any of these described issues? Does chain timing still uses a wet belt for oil pump and still clog the oil strainer?

These are really good engines but need regular maintenance all the ones I look after I tell them 5k oil changes

My car is worth 4500 dollars and the engine used is 4000 What the hell . How is that even possible

Excellent forensic reveal on Ford nonsense engine.
