Does the 1.5L Ecoboost engine have a timing chain or timing belt?

Recommended Posts

It's unclear to me after doing some research whether it's a belt or a chain.

 

If it is a belt what is the recommended interval change (couldn't find anything in the owner's manual) hence my question. Also is the 1.5L an Interference engine?

I just did a bit of research on the Belts in Oil system and I'll be the first to admit this is a technology I was not familiar with.

Although I still couldn't find a definitive answer to my question on maintenance it looks like it is more of a "lifetime" item and wouldn't require changing like a traditional timing belt.

Not familiar either..........but.......having spent quite a bit of time in VW land I'm very skeptical of "lifetime" anything. First of all one must define "lifetime" - often the company's idea doesn't match the customer. Much like timing chains, properly engineered belts have a far better track record - chains are advertised to "lifetime" and very often aren't. Belt changes are just fine in my book, costly but the service interval is generally around 100K = how many will you actually have done? One?

 

Interference? I'd bet yes, haven't seen an engine in recent memory that wasn't.

Ford Europe - Ecoboost engines 1.0L / 1.5L -The timing belt with oil bath -Change interval: 240,000 km (149,130 miles) / ten years.

 

Not sure what Ford North America will determine based on driving patterns and conditions in North America.

In my owners manual on page 433 it does mention that the timing belt should be replaced on the 1.6L engine at 150,000 miles. It does not mention anything about the 1.5L engine. Are the 1.5L and 1.6L engine essentially the same?

 

I think it will be expensive to replace. I have watched the videos of the 3 cylinder ecoboost and it shows the oil bathed belt. From what I can tell, the job will be labor intensive and require the removal of the sealed cover which also means the flywheel has to come off and I suppose other components as well so you can get to the cover.

Yes, both engines are based on the 20 year old Sigma engine family; both use a timing belt. The main differences (other than 97 cc of displacement) for the 1.5L unit are: exhaust manifold integrated into the engine block, a water cooled CAC, and a computer controlled clutch for the water pump.

And which engine has those.......the 1.5 or 1.6 ???

I'm late to the party guys just purchased a 2016 1.5 EcoBoost. Does this have a timing belt in oil bath or is it just a straight up belt system that needs to be replaced at 100000 miles? I'm confused. Ford doesnt even seem to know which is strange.

1.5, 1.6 are interference engines with NON oil bath timing belts. I believe there is a spec for the 1.6(150k miles if I recall), but I don't believe there is a written spec for the 1.5. Either way, if I had one, I wouldn't let it go past 125k. I believe there is a time limit on the 1.6 also, but I cannot remember it off top of my head.

The Owners Manual for my '17 1.5L EB says to replace the timing belt at 150K miles.  I knew that it had a belt before purchase and was shying away but then the deals started.  I still think it's lousy in this day and age when chains are the norm.

What's the difference if both are rated for 150K miles?   I also thought belts were the norm on small engines.

They are on all the old Zetec based architecture. Duratec based engines have always had chains. The old LIMA and the 1.9 sohc in escort were belt as well. GM's current Ecotec are all chain I believe.

Chains NEVER require maintenance or replacement.

It's my understanding that eventually, chains can stretch and throw off the timing as they do. From what I've read (as it's never happened to me),  much less devastating than snapping a belt on an interference engine.

They do stretch and they can break.  I broke one on my 75 cutlass.  I don’t think interference has to do with a belt vs chain though.

if the belt lasts 150k miles it’s a moot point.
