First, sorry for the repeat question, but I cannot find an unambiguous answer.

I have a 2022 Fiesta ST3 3-door (I presume this was amongst the last of that particular model).

What type of belts and/or chains (dry or wet) does it have for the timing and oil pump?

 

Again, apologies for the repeat question (ducks)

Hi,

For a 2022, chain cam drive, wet belt for the oil pump drive.

(Some very early cars up to around February 2019, had a gear driven oil pump.)

thank you!

I sort of expected that (the amount of noise on the net about this is incredible) but I had a service yesterday, and I asked the clerk at Ford's and they said it had a dry timing belt, only the Mustang had a chain, and I thought "what?" Hence my confusion (or greater confusion)

Thanks for clearing it up.

Are there any particular issues with the wet belt for the oil pump?

Additionally, what are your recommendations for checking/replacing the drive chain and oil pump belt? Again, lots of conflicting information (clerk at Ford's said 150,000 miles....).

 

cheers

Good to know the Ford service desk is fully up to speed.

Is it only the Mustang Mach-E that has a timing chain ? 🤣

Early days yet but service on time with the correct oil is still the No 1 recommendation I guess. Annual service in the ST anyway of course.

Ford recommend 150k miles/10 years but (if I still had the car by then), I think personally I'd look into doing it a couple of years early, along with the chain, which has to be removed to get to the belt anyway.

 

 

 

 

thanks again!

I rest my case

I've been getting the car serviced as per Ford's recommendations. Just had 35,000 mile service (at 34,500 miles). Next one in 12 months or at 47,000.

With the wet oil belt issues, do people recommend servicing earlier?

You can never change the oil often enough, even every week is OK, I doubt anybody does that though other than motorsports

It's entirely up to you

You've also got the "Intelligent Oil Life Monitor" which, in theory at least, should tell you if an earlier oil change is necessary.

My experience of this so far, though, over 7 years and two Mk 8 Fiestas, is it gives a message a couple of weeks before a service is due on a time basis anyway.

What is "intelligent" about it?

The car did say "change oil soon"; for a few weeks; then "change oil".

I thought it was simply an alarm clock that is reset after a service?

Some cars have an oil quality sensor.  It's basically measuring viscosity & water content.  As the oil degrades, the PCM uses sensor readings to adjust the remaining oil life down.

If it reaches the full year in time before the oil degrades through sensor readings, then that over-rides the intelligent system.

So far I haven't been able to work out exactly which engines have the sensor, and which are just relying on conventional time & distance.

Theoretically it should monitor oil condition and advise an earlier change it necessary, e.g. If the car has been doing lots of very short journeys. I've always found it comes up just before service anyway, which could be correct or just coincidence. Other members have however reported they get the message several thousand miles before the service is due based on time.

VW Group have a similar system when on their Variable Extended Servicing regime in conjunction with specific oil and I certainly found that seemed to work on oil condition on my Audis.

Ford say:

INTELLIGENT OIL LIFE MONITOR

The way you drive can significantly affect how often you need an oil change. The Intelligent Oil-Life Monitor (IOLM) in Ford vehicles monitors your engine oil and will alert you with a message in the instrument cluster if the oil needs changing.

To help increase the time between your oil change intervals, we recommend the following:

• Avoid leaving the engine running when at a standstill. This increases fuel consumption and causes unnecessary wear to your engine.
• If you don’t use your vehicle regularly, try to ensure you run it above 1,700 rpm for at least 15 minutes every week.
• If the message ”oil change required” is displayed, please contact your local Ford Dealer.
• The IOLM will be reset by your Ford Dealer after the engine oil has been changed.

1700rpm for 15 minutes every week!?  My neighbours are going to love that...

I guess they mean drive it somewhere rather than run it when parked.........

They don't make that clear, though!

Another advantage to an EV - no nasty oil to deteriorate!😀

Sorry but that is not an advantage of an EV as I'm sure many will confirm.

Note: this is not my Mom's car.

I'm not so sure...  1700rpm would be above cruising speed for a diesel anywhere other than a motorway.  (Unless that passage is ST specific?).  I'm sure 70mph in 6th was about 1800rpm.  Though I might be misremembering now.

I would swap my diesel for an EV immediately if I had somewhere to charge it.  Actually looked at a property with solar panels last year which would have made EV charging even cheaper...lost it at the last minute through no fault of my own.  Haven't found anything else suitable since.

Now considering how best to try and boost the 12v batteries on the ICE cars before summer heat returns.  Already had a few weeks of intense heat down here so my plan to run engines every 2-4 weeks went out the window!  It is a bit cooler this weekend.  I'm considering a 20 minute idle (not 1700rpm!) followed by smartcharger and lithium powerbank left overnight until it drains completely.  Not sure I'm comfortable leaving the powerbank draining in the car all night though.  If it does catch fire it would probably take out my neighbours car as well.  Also playing fuel light roulette when idling as the range was lost when the new battery was fitted, and the car hasn't moved since.  I'll have to ask someone to bring me a can of diesel soon if I do keep running them.  EV would be considerably less hassle for me at least.

looked into this.

It appears that rather than having a sensor, the intelligent monitor is an algorithm that monitors the cumulative engine load and adjusts the oil life monitor accordingly so that the oil change warning is the least of:

1) time 

2) mileage

3) engine loading

?

Most of the newer Ford engines do have a sump sensor.  It's listed as level sensor in the catalogue, but I'm not sure whether it incorporates a quality sensor or not.

What car is that? I guess you still need a service/inspection at some time anyway, and they just haven't changed the message from an ICE or hybrid version.

Looks pretty silly, though!

No, it's just a generic note on Ford's service site. The ST only does 26mph/1000rpm in top anyway, so only about 44 at 1700rpm, you need about 2700rpm in top for 70. A 140 1.0 ecoboost would be similar.

I did need to considerably recalibrate my perception of appropriate rpm when returning to petrol after 25+years of diesel driving!

Many if not all EV's require oil change/service, including Tesla.

The EV drive unit uses a lubricant, typically Pentosin ATF 9. While not an "oil change" in the traditional sense, the drive unit does require periodic maintenance, including changing the gearbox fluid and replacing the oil filter.

Yes, that makes perfect sense. That screen message is a bit confusing!

Yes a little.

Not like the clear message that Ford give like "Engine - Service Now" when they mean engine knackered 🤣

Yep. I have seen on the internet/FB a joke or meme about Teslas needing an oil and filter change. However it is true, they do have filters for the gear unit/transmission. Some have 2 filters, one for each pair of driving wheels. (front and rear). However from what I've read, it only has to changed every 100 k miles.

Sorry to OP for going

It's not an actual set in stone interval but the car will normally determine when it needs doing and as a general rule it works out between 50,000 and 60,000 Miles. Cost for the service kit for a model 3 is approx £525
