david lloyd Posted May 12, 2023 Share Posted May 12, 2023 Thanks Robinhood - sadly, this 2006 (x244) Renoir has the 2.8hdi - which is a brilliant engine but does have a cam belt when I checked the VIN with Peugeot. David Quote Link to comment Share on other sites More sharing options...
Derek Uzzell Posted May 12, 2023 Share Posted May 12, 2023 David's motorhome is a 2006 Autocruise Pioneer "Renoir" - Peugeot Boxer-based and (as he has just said) fitted with the 2.8HDi (Iveco 8140.43S) power-plant. This motor does have a timing-belt, but its design will differ significantly from the 2.3 Multijet (Iveco F1AE3481x) motor in Colin's Ducato-based motorhome that was being discussed earlier in this thread. The Iveco 8140.43S 2.8litre motor was also fitted to Ducato (then called 2.8JTD), so Nick Fisher (euroserv) should be able to advise on what the belt-change involves, whether it would be a good idea to replace ancillaries (eg. the water pump) and if critical bolts should be replaced or may be reused. Plenty of on-line bedtime reading about this - GOOGLE on fiat 2.8jtd cam belt change Quote Link to comment Share on other sites More sharing options...
david lloyd Posted May 12, 2023 Share Posted May 12, 2023 Thanks Derek - have just booked it in with Leisuretech NE to have the service done earlier than expected in June (so that I can then book it into Big Fish Garage to do the Dyno remap) and they confirm the work will include changing the water pump and tensioners as they all come in a kit.

colin Posted May 12, 2023 Author Share Posted May 12, 2023 Going back to my OP, I've replaced the tensioner pulley bolt with a new one from Fiat, the original head markings where indistinct, but at a guess it was a stretch bolt, the new bolt is a 10.9 high tensile bolt, so I see little need to replace this in future, the idlier bolt is still questionable, the original appears to be a Fiat specific bolt and head is stamped with what looks to be a reference number, the SKF replacement is a 10.9 high tensile bolt and washer.

David I believe the 2.8HDi motor's water-pump is not driven by the timing-belt but by a separate multi-V belt, and timing-belt 'kits' for this motor are advertised on-line with or without the water-pump included. But if your 2006 motor still has its original water-pump, replacing the pump now would make good sense. (I admire your bravery to be remapping a 17-years-old motor.)

david lloyd Posted May 13, 2023 Share Posted May 13, 2023 Thanks Derek - yes she is getting on a bit but so am I and can’t spend the rest of my life trying to get her up inclines! Spoke at length with Big Fish Garage (specialist tuning) near me who wouldn’t attempt a retune unless there was a significant benefit and are confident the results will meet my expectations. Renoir has done 47k so plenty of life left in it. As regards the water pump, although there is a fairly comprehensive service history I can’t find anything relating to a cam belt change or water pump replacement. It may well have been carried out but the previous owner, who seems to have had it for over ten years, wasn’t in a great hurry to change things. The (Maxxis) van tyres were 11 years old and the twin leisure batteries seem to have been 12 years old…… I tend to err on the side of caution and will be more reassured with the cam belt/water pump done - the remap is a bit of a luxury item though.

Derek Uzzell Posted May 13, 2023 Share Posted May 13, 2023 This link relates to a Celtic Tuning remap of the 2.8JTD motor (same as your 2.8HDi) and the bhp/torque increases are what you could expect. https://www.celtictuning.co.uk/services/performance-stats/fiat/ducato-gen-2-1994-2006/diesel/2-8-jtd-127-bhp-1994-2006-ECU-remap-chiptuning/stage-1 Quote Link to comment Share on other sites More sharing options...
onecal Posted May 13, 2023 Share Posted May 13, 2023 (edited) Hi David , You are right to error on the side of caution and replace all Just a heads up on the tuning remap, make sure the cooling system gets a good flush out and checking before refilling with coolant. This is often gets overlooked and can cause some problems the odd time Best of luck with it Regards Edited May 13, 2023 by onecal Quote Link to comment Share on other sites More sharing options...

All said from 123bho to 152bhp (+24%) and from 300nm to 360nm (+20%). This is a bit less shown in the example in the link you provided but I would be happy with that. The examples I got were all ‘stock’ maps from the likes of Quantum but Big Fish Garage will custom tune it based on the rolling road data. I checked with my insurer (Caravan Guard) who have confirmed that, providing the bhp increase is below 30% they just need notifying it has been carried out by a professional tuning agent.

weldted Posted May 13, 2023 Share Posted May 13, 2023 Whatever tuning one might do, remember diesels like plenty of clear air, and clean fuel. Weakest point with the extra torque is the clutch. If on a motorhome that may spend a lot of time standing, check handbrake releases fully, and tyre pressures correct. All add up to efficiency.

onecal Posted May 14, 2023 Share Posted May 14, 2023 I am afraid so with a lot of modern diesels they do not have a lot of redundancy in their cooling system also as they get on a bit , we have found the odd time it does become an issue Usually a good flush out and refill of coolant works with a small power gain without issue Regards Quote Link to comment Share on other sites More sharing options...
david lloyd Posted June 26, 2023 Share Posted June 26, 2023 Just an update on this old thread. My Renoir went in on Wednesday last week for a service, cambelt change and the cooling system flushed and replenished. Today it went in for the remap. The initial run on the rolling road showed both power and torque were well down on the manufacturers claimed performance. Never expected that. 114.2 HP ( instead of 127) @ 3550 rpm 260.1 Nm of torque @ 2309 rpm After establishing these baselines they create their own bespoke mapping to get the best out of the retune whilst staying within required tolerances (e.g. emissions) and the end results were: 143.3 HP @ 3552 rpm 327.6 Nm @ 2470 rpm Quite a significant increase in both respects and, whilst I have yet to tackle any serious inclines, the drive home was in itself a revelation. Far smoother take up, lower revs at my normal speeds and it seems quieter too. So far, so good. Will be giving it a good test in a couple of weeks when we travel into Wharfedale. Thanks to everyone for their input. David Quote Link to comment Share on other sites More sharing options...
teccer1234 Posted June 26, 2023 Share Posted June 26, 2023 having my cam belt changed in a couple weeks on my hymer B694, (2001) first changed at 60k, now 100k, the garage first said they always change the water pump and auxiliary belt at the same time, then after checking said that as the water pump is not run by the cam belt so not sure if they will replace the water pump at the same time, maybe I should give them a call and ask them to do the water pump as well, correct in my thinking? (hope the pump comes out easy! many years ago on my old hymer 544 the water pump needed replacing while in Spain the Fiat garage could not withdraw the old pump out, (wheel arch in the way) short story, took 2 days with us sleeping in the garage, knackered the bearings in the gearbox trying to lever the motor over forcing the drive shaft into the gear box, drove home in 4th gear then at home had gear box out and all bearings replaced.
