Peugeot Cambelt change interval different from Fiat

[dunnah01]

I doubt it. It's one or the other, the belt will be the ancillary belt that drives the water pump, alternator, air conditioning etc. and the chain for the distribution.

The belt drives one camshaft and the chain drives the other cam off the first camshaft

Really? That's interesting to say the least.

Fiat 2.3 engines have had this drive arrangement since they changed from chain drive sometimes between 2012 and 2014. I couldn't say if the new 2.2 drive is this arrangement though.

Here is the Peugeot version, for various items, for reference

View attachment 1017693

From this I read that Peugeot are saying that the belt is good for ten years life span which I would agree with. I changed mine at 7 years, 22k miles, and the belt was in excellent condition. I also fitted a new water pump and it was as new.

For any one who is concerned about the water pump failing it is built very well and not like any pump I've seen in terms of robustness, I will not be changing mine ever again and would be happy to refit the one I removed.

Peugeot have kept the mileage as 96k though so are saying the same as fiat with respect to wear of the belt.

I bought my Peugeot Boxer based AutoSleeper motorhome new in 2014, so I'm guessing its Ford Puma engine was built maybe 2013, and I've always been under the impression (from mechanics) that because it has a timing chain, not belt, that it will never need changing. The engine has currently done 105,400 miles without me giving it much thought - until now! Coincidentally, it's booked in for a service next week, ahead of shipping to Canada in a couple of months for a trip, so I'll raise the issue then - maybe even timing chains need replacing at some point.
Irritatingly, not all components have been as reliable - the odometer, while still working, has been constantly flashing on/off since around 102,000 miles (Peugeot have no idea why!) and the DPF gave me big problems and put me into limp mode at 77,260 miles.

The new 2.2 engine that is common across Fiat, Peugeot, Citron came out in 2021.

Additional info
It was only used by Peugeot Citroen until 2023 when Fiat "adopted" it.
Fiat Euro 6 engines
2016-2019 2.3 Twin EGR
2019-2021 2.3 Adblue
2021-2023 2.2 Fiat Pratola Serra MultiJet III Adblue
23 onwards 2.2 PSA DW12 Adblue

I have been assured by the local Citroën dealer that the interval for the distribution kit is 150,000km or 10 years. I also have it in writing. As it is only 8 months old as we speak, I am still sitting on the fence on this one for now.

You might have it in writing Barrie but that won't extend your warranty.

 

[Pausim]

If it has not been asked already, do the engine builders recommending different time intervals use belts of different materials? If not what is the difference in the technical specifications/use of the belt?

I was told by an engineer it was the geometry of the engine not the materials that make a difference. If the belt goes through lots of tight bends it will wear quicker than one which only has gentle bends in it.

 

[oldiesontour]

Having read through this thread, I'm still of the belief that no matter what or when fiat,ford,Citroen, Peugeot,say in writing or otherwise all amounts to recommendations not warranty..with endless get outs,harsh environment,foreign bodies etc,so the only real possible warranty is that given by the vehicle producer or part manufacturer,even this is open to dispute

My 2024 Series 9 Fiat Ducato has the new MultiJet3 2.2 engine. Fiat are advertising the current Ducato Series 10 as being powered by the MultiJet3 2.2 engine. They now appear to be using this new 2184cc engine widely across the PSA brands. I am not aware of any Ducatos having the older 2179cc DW12 engines.

...but it gives an excellent basis for a small claims court proceeding.

I had a Maserati V8 with two pairs of cams with a belt drive to one and a chain to the second on each bank - that was a proper head scratcher to change the belt

 

[nelson8217]

I suspect that the 2.3 X250 Fiat engine also have a similar TRUE belt change interval because the last TWO I have changed since I bought the vehicle ( one at 5000mls interval and the second, 6000mls later,) have BOTH been in excellent condition.

I think Fiat's 5000ml interval is both to make money and to cover their backsides!

Sorry to butt in but, so far as I know, the 2.3 Fiat Ducato 250 belt should be changed every 5 years irrespective of the mileage. According to Nick Fisher from the MMM, the water pump on this engine is designed to last the life of the engine but it is important to replace the tensioner pulley and bolt.
I had mine done at the 5 year interval and left the water pump, so far so good, but you never get any warning with cambelts, luckily it's not a wet belt!

 

[jockaneezer]

I follow the mechanic Baz Meredith on YouTube, he changes a lot of wet belts, but the thing I noticed is that for the cost of say three or four oil seals, they could have a "standard" outboard timing belt on these newer engines and you would save the cost of the wet belt cover which tends to need replacing at the belt change to maintain the oil "tightness" ?
I don't know why the designers came up with the wet belt idea, I can't think of any advantages as it doesn't seem to be any quieter than an outboard belt, it's harder to inspect and change ?
There have been a couple of documented instances of a road stone or an icicle getting into the belt and causing the timing to jump on an outboard setup, but these must be much rarer than the engine failures due to the pernicious nature of a rubber belt, slowly degrading and blocking up the oil pump and galleries ?

Is that Citroen dealer willing to back that verbal assurance up with proper financial security - such as £10K deposited with a firm of solicitors in a stakeholder account in case of a replacement engine required, caused by a premature timing belt failure? Hmmm.

Same with the claim " it's designed to last the life of the engine"(I'm sure (well at least I hope) air bag ECUs were designed to last longer than they do,same with adblue systems) How long is the warranty on a water pump ?

Claiming under a manufacturer's warranty can be a battle all of its own. Been there, got the T-shirt. I did win in the end but it was very stressful.

Manufacturer's customer service manager took the view that their internal company policy (something that they keep to themselves) overrides the actual warranty wording.

Most embarrassing!

The above post by me should read 5 & 6 YEARS, NOT 5 & 6000 MILES!

Sorry, Senior Moment!

It's a bit early to be drinking I would have thought

 

[Whizzo]

Peace of mind for me. 25k miles 7 years. Didn’t realise at the time that fiat stated 5 years. Will get it done on time as will have more mileage then.

Quite correct, the1andonly's information is I'm afraid wrong.

Series10, mid '24 onwards all variants (Ducato, Boxer, Relay, Movano, Proace Max) use the 2184cc 83.8x99 FPT Family B (Pratola Serra plant) engine. It's quite clear in all the brands' technical specifications and is confirmed on the CoCs of new vans (or by looking under the bonnet).

 

[nicholsong]

Just an add-on to this thread - I was discussing my timing belt interval on our 2002 Fiat 2.8itd engine with our very experienced commercial workshop owner, and his opinion was that I should leave the change till 7 years, and that is what he would do if it were his vehicle. % years is probably 25,000 miles for me.

I am taking his advice, even though he changed my last one at 5 years - on my instructions..

Now, it’s a bit embarrassing admitting this since I’m an engineer, but here goes…
I knew Peugeot, Citroen and Fiat cabs used for Motorhomes are all assembled on the same production line and I naively assumed there were only cosmetic differences to differentiate between them.
When I took my Peugeot Boxer based Motorhome for its MOT recently at a Peugeot main dealer I inquired about a price for changing the belt and was told it was not needed until 10 years or 96k miles.
I did some digging and discovered that, contrary to what I thought, Peugeot put their own engines in Boxers, hence the difference from Fiat’s recommendations.
Now I may be the only person on this forum who did not realise this, as I have since discovered other threads that mention this, but I’d never come across them before.
I am well aware of the dangers of a belt failing, and I will probably change mine before 10 years anyway. Everyone will have their opinion, but that is not really what this thread is intended for.
It’s just in case you have a Boxer-based unit and didn’t know. I suspect Citroen-based units will be the same.
Edit: mine is a 2018 build. Later or earlier models may be different!

I have a 2016 Majestic 135 and asked my local Peugeot dealer last year about the belt and he confirmed what you have said. 10 years or 96K.

 

[The joker]

Each to their ownHad mine done in Feb. Thought it would be best to as it's only a guide when needs replacing, if you have had your vehicle from new you know how its used, 2018 Boxer

Absolutely agree re the wet belts.
Whoever decided that they were a good idea should be taken outside and shot!
I will not go near a post 2016 Transit based motorhome because of the wet belt engine.
Seen several failures of these engines along with the PSA Puretech petrol engines, and also Ford’s EcoBoost units.

i have fitted a wet belt on a transit it was a bit involved and a bit strange but it went ok .it was like somthing' the french would do in the 80.s..... i hope they dont put that crap in new vw transporter witch is a badged up transit

My Citroën based vehicle has the cambelt change specified at 10 years or 150,000km (93,000 miles) so the same as the Peugeot.

Edit: I just realised that I already posted this a while back. Sorry for repeating myself

I believe Ford have revised the wet cam belt change from 10 years to 6 years because of the problems.

They have.

All Ford engines now, diesel, hybrid, (both wet belt) and electric.

i wouldn't personally wait that long. And the workshop I took mine too (which works on motorhomes) mentioned they've had a fair few customers fail waiting till 10 years. Remember motorhomes are not driven as hard as delivery van's -> and many van's don't make 10 years of intensive use before being replaced.

But everyones risk appetitite is their risk appetitite. I waited until 6 years on my 2019 Peogeut and had it done ahead of this seasons trips to France as didn't want to get stranded in France through a failure.
