1.0 EcoBoost 'wet belt' issue

Hi Sarah, thank you for keeping this forum informed of your progress (or is that lack of ?).

I do hope you make some headway with your claim and that it can be resolved to your total satisfaction. It will be of much help to others if you can keep updating this thread.

Of course there was nothing wrong with the total design or concept of a Wet Belt, that's why Ford have now stopped using them and changed the design back to using a timing chain.

Good Luck 馃

Not sure Ford have stopped using wet belts.

just bought a 2022 eco sport 聽140ps and service info through ETIS says Belt replacement at 10yrs 150k miles.

Also oil pump drive may be welt belt.

someone on here said cat between rad and engine - wet belt, cat between engine and bulkhead - chain. 1.0 eco boost.

In my opinion the only reason why Ford switched to a timing chain on the 2nd generation 1.0 ECOboost is cost reduction. A wetbelt + tensioner is approximately 33% more expensive than a chain + guides and tensioners.聽

The 2nd generation of the 1.0 ECOboost may have a timing chain but it also still has a wetbelt between the crankshaft and the oil pump (and balance shaft on automatic transmissions). Since this is the wetbelt that usually disintegrates I do not expect much improvement in reliability.

On the other hand the days that a timing chain was well overdimensioned / overengineered are long gone. To reduce friction and meet emission standards glorified bicycle chains are used. Many manufacturers struggle with the reliability of these chains. Chain stretch and wear is quite common.聽

The EcoSport is reaching the end of it's production run.聽 They're basically just using up the old parts now.聽 The 140ps 1.0 hasn't been available in the Fiesta or Focus for some time now.聽 Replaced by the 155 MHEV which uses a chain.聽 I think all 140s are wetbelt but may be corrected there.

That's my understanding too, as afaik the Ecosport never got the revised engine. I think @ianttmentioned somewhere that the 100ps Fiestas had continued to use the original version with wetbelt, though. I presume the same would apply to the non-turbo engine?

Yeah, 100ps still does. The same engine is still fitted to commercial range too, courier , fiesta van and think the connect too.聽

Well as expected this is becoming a long drawn out process. Was due an update last Wednesday but they couldn't give it as the Master Technician had gone on holiday and there was no one else in the whole of the Ford SMC building that could determine what to do. A walk down to the Dealership to get things straight proved helpful, as our contact confirmed Ford had just offered a goodwill to another customer on a new engine meaning he had to pay 拢500 towards it - so a lot of this is going on.

Roll on to today, and Ford Customer Relations have called and said that as the car was sent to them without the engine being put back together after the garage it was towed to had looked at it - the Dealership is now trying to get costs sorted for agreement to put the engine back together, so that they can then take it apart and test ( and confirm ) it doesn't work. So we are currently down the costs of having the car looked at after it broke down ( 拢200 ) then to be towed to Ford ( 拢84 ) and now whatever costs they come up with to put certain parts back together then any labour and then a cost for the damage(s).聽 It's amazing how they can come up with a cost on the spot when cars are serviced - but not for this. This requires a whole "trying to get costs" scenario.

So we are now working on an email to Nigel Brackenbury VP Ford Customer service Division Ford of Europe telling him what we think of that idea, and a Section 9 declaration from the garage where the car was originally towed to state that the car is in the state it is in due to the malfunction of the engine and nothing they or us have done. This documentation is admissable in a court of law and will be put forward if/when we get to that stage as Ford have started to say that it was something the garage have done as they now can't use the service / oil argument as everything is documented with them to say it was all done on time.

I am so angry as this is the 5th week we have now been without the car, public transport for my partner to get to work is 拢40 a day and they are just dragging their feet. Mr Brackenbury needs to stand by.

Update on our ongoing saga聽馃檪..聽So after lots of arguing Ford have now managed to look at the engine without putting it back together again, or charging us for the privilege聽 - amazing what they can do when you apply some pressure.

They have determined the engine failed due to all the teeth coming off the wet belt and getting into the engine causing the failure... also explains why we were still able to turn the engine over ( but with a lot of grinding noise). They have quoted 拢7,108 for a new engine - but will only give it 1 years warranty once replaced, which I can't help thinking shows their lack of trust in it if they will only warranty a new engine for 1 year !!聽 聽They are sending over all the paperwork to Ford today with their findings and we now just have to wait and see what they say. We are still keeping up the pressure, and have complaints listed at the Franchisee, the Customer service team, and a call to the motor ombudsman and we are just hoping that this will be of help.

Thanks for the update, Sarah - it really is becoming quite a saga, but delighted that you have at least got the full diagnosis without having to bear the cost. I think the 12 months is a standard Ford thing on replacement parts, but not confidence inspiring as you say.

Wishing you all the best with the next stage!

Hi Sarah, once again thank you for keeping us all informed of your ...... was going to say progress but I think as you say, saga is probably better.

I assume that price (拢7108) is a new engine fully fitted.

Keep pilling the pressure on, if this was the USA there would be a multi million dollar class action law suit going on over this problem.

Best of luck.

If you're meaning Fox/Duratec engines (1.0, 1.1, 1.25, 1.4 and 1.6 TI-VCT) as non-turbo, doesn't they all fitted with normal belt.

I think, wet belt introduced for petrol engines in Ecoboost (earlier used in 1.8 TDCi), but never used in Duratec.

The 1.0 and 1.1 fox/duratec in non turbo form are still wet belt timing belt and oil pump belt.聽

I was referring only to the normally aspirated 3 cylinder engines derived from the 1.0 ecoboost and whether they retained the wet belt like the 100ps version of the ecoboost, as Ian has confirmed above.

Keep going Sarah46. I do hope you get a positive outcome.

A number of ppl posting on the 'Ecoboom' Facebook page have had varying degrees of success.

We are trying Ray - although yesterday we had to pay the Dealership a visit as Ford now can't determine whether the teeth loss on the wet belt is a manufacture problem or not, and were going to put the engine back together and dismantle it again to find out. This would now be the 3rd time this has been done on the car and all the time these costs are building. So a visit was required to sort them out as I don't know how they could think that they would come off any other way ? and how do you determine that when they are not there anymore ?

The heat did not help with my temper 馃檪聽but they finally agreed not to put the engine back and filled out the documents to send to Ford to make a decision. They did admit whilst we were there that they had a 2019 1.0 ecoboost ST in with the same problem which is a lease car, higher mileage than ours, all serviced ( but not with Ford ) but they offered to cover 42% of a new engine, so I am secretly keeping fingers crossed.

Keep going Sarah !!

How this farce is allowed to continue is beyond me. Maybe all those solicitors who used to chase PPI could divert there talents (using that word very loosely) to the Ecoboost problems.

What the point of that would be when it's already in bits escapes me!

Keep plugging away!
