I’ve seen this several times over the years. This is the first Volvo seen with it but Fords, Merc and several others. Not unusual unfortunately - key is get your car serviced regularly.
Good morning Rob and Chris, another great video, just arrived in India, watching you both from New Delhi. Thank you for taking the time to upload another video. Ged
Yep. D4/D5 engines do that. 54,000 for the aux belt and 108,000 for the cam belt. If you rebuild the car check the rear suspension bushes (rubber cushions on the rear pivot point) and the front screen isnt leaking as they are a known fault for coming unbonded. Its a pre 2014 model (twin round exhausts) so it's likely to be one that does.
I service my XC70 every year regardless of mileage. Usually 3-4k a year. That belt is less than £20 and takes few min to replace so I replace it as well. Preventative maintenance. I also recommend doing gearbox oil flush and change. Volvo as every other manufacturer says it’s lifetime fluid but it’s not. Same with Haldex and rear diff fluid. Wont be a big project for you guys, but will be more costly than others. Looking forward to next videos on this car.
It is not the belt, but the tensioner seizing that is the problem. Closer to £100 for a OEM belt and tensioner. Then a couple of hours to fit if you are not a spanner monkey (most people aren’t). Costs rack up. Not saying it is not worth it, just that it isn’t £20. Biggest problem is that when cars get bought and sold and maintenance is done outside of the Volvo network (who uses Volvo at £150+/h once the car is well out of warranty), the catastrophic consequences of changing the belt/tensioner are not known.
@@davidstuart9695 yes, in most cases it’s either the tensioner or alternator clutch pulley that causes the wear on the belt. I have both of those changed on mine. But even then after about a year I notice sides of belt getting shredded slightly. So for my piece of mind I change it every year with the oil and filter service. The other part of the problem is people who either don’t know or don’t want to know anything. That’s why whenever I buy a car I change all fluids and belts regardless of how extensive the service history is.
@C H no, because you’re supposed to service it every 10k miles or 12 months. Some people only go by mileage and ignore the age. And since I do it myself full service with original parts cost me £150. That’s nothing for annual service.
Had exactly same problem after aux belt failure on an XC90, but it smashed most of the tappets out of the head! I highly recommend Autotech Cylinder Heads down in Cornwall... they actually repair these heads and supply fully re-conditioned at a reasonable price, they also supplied me with the full head gasket set and bolts... defo worth a shout!
Full credit to the mechanic at Volvo- he diagnosed the situation perfectly and provided advice to the owners (albeit pretty unwelcome guidance) without needing to massively disassemble (and run up more costs). Liked the additional touch of removing starter relay too! Rubbish situation allround though.
Thank you. I love how you both address whether a car is worth repairing, then methodically work through it all. No long rants, screaming meltdowns, spanners flying across the workshop.....
Nice bit of investigation there gentlemen. I’m always impressed by how easy you both make it look and the methodical approach to checking out the various options. Looking forward to the follow up on this one. Cheers guys.
It is important to use Volvo's own belts. They don't fray in the same way, they break straight off instead. The reason that the belts break is that you drive them for too long or that you have bad idlers or freewheels on the generator.
I am totally hooked on your videos. I love how in depth you go and how much care u guys do when repairing a car, thank you to you and Chris for all the videos you do and appreciate all u do
I stick to old rear wheel drive Volvo redblocks. 2.3 litre petrol. Had 3 over the last 20 years. 1986 740 GLE, B230K, carb, manual estate in 2003, £425. Owned 6years. 1989 240 GLT Auto estate. Daily driver for 8 years, owned 10 years. Paid £350, sold for £500 in 2018 with 233,000 miles. Ran perfect. Now have a 1996 940 auto estate with the B230FK, petrol, Low pressure turbo,auto estate. Again cost £250 6 years ago. On 208,000 miles. All bought cheaply and easy to look after. A good reliable workhorse. My 940 is a non interference design but change the cambelt for a genuine Volvo one and tensioner every 5 years or 50,000miles, whichever comes first.
Volvo Mechanich here, this is typicall when the aux belt breaks on these, The cylinder head gets all the beating, the hole where t he hydraulic tappers is placed in breaks. the piston and engine block it self "never" breakes. A new head and the engine is back up and running with no problems. One of the main reasion for the aux belt to go bad is the freewheel on the alternator. check that carefully before reasembly
Hi there, recently bought a volvo xc60 2017 R des from copart, 73k on the mile, nice on the outside, couple of issues as I received it, it's a run and drive but with the following error codes on the dash: ESC service required, soot filter full, city safety service required ( idk what this is ) ESC temporarily off. Now I knew from the start this car would be needing some maitenance, but I got it for a good deal, so investing in it wont be so bad, it depends how much would it cost me if you'd know? I got my mechanic booked for Thursday but I'm on pins and needles by then!
Seen this time and time again on the d5 engines. Aux belt goes into the cambelt, puts the timing out, piston hits valves, the force goes through the valve, into the hydraulic lifter and shatters it out of the cylinder head. As soon as the rocker cover/inlet is removed you will see the carnage! Replaced a few cylinder heads because of this issue in my time 👍
Snapped the aux belt on our XC70 last year at 70k and it just dropped to the floor. Thought nothing of it and simply got it replaced. Didn’t realise the risk that this could happen and how lucky we were!! Look forward to pt2…
A common issue on D5 Volvo's - its the Alternator clutch pulley seizing that normally causes it. Very strange to see it go at such a low milage though - my own owned from new D5 needed a new alternator pulley at 196k miles.
This is a common fault on modern engines, usually the first part to fail is the aux belt tensioner (it starts to rattle) it then causes the belt to shred, then the shredded belt gets wrapped around the timing belt crank pulley which then causes the timing belt to slip and jump teeth, very few engines are non interference. So if you here that tensioner rattling get it fixed ASAP
I'm a big fan of these cars. I drive one, my wife drives one and I've bought, fixed & sold many over the last few years. I haven't started watching the video yet but if its belt related, the castings in the cylinder head will have sheared off. Autotech Cylinder Heads in Cornwall do exchange heads with UPS delivery, they aren't cheap but you'll definitely make your money back & then some. When I have one of these to sell, the phone rings off the hook and it's normally gone in a couple of days.
@@sruk Have you bought one ? interesting if they re weld them and re machine them ? ready to fit for a bag of sand understand why so many sold for spares or repair due to parts costs and labour rates never mind a stealer charges
@@sruk Excellent, you may as well stop searching now, I went through the same trauma last year and Ian was fantastic. Good news is yours is a D4 AWD, so only 1 turbo to remove! You'll do so much better in this deal than I did with mine, looking forward to seeing it all done.
@@mondodaftasabrush Yes they re-weld and re-machine the head, check the cams, rockers, tappets etc and fit replacements if required and ship it out with UPS which is 1-2 day delivery. They also call you up and give you tons of fitting & parts advice without having to ask. I used them last year and they were the smoothest part of the repair process. The price is plus VAT and they waived the core charge despite never dealing with me before, all they asked was that the head was packaged as they sent it and to call them when it was ready to collect.
Amazed that a failing auxiliary belt caused that much damage. If it had been the cam belt it would be more understandable. Thanks for another interesting video. Good luck with getting another head at a viable price. It looks like there are recon ones out there.
Interesting video, as an XC60 owner who has replaced my belts and pulleys at 100k(all Volvo parts fortunately), I look forward to seeing how this pans out. Had never heard of this scenario before, looking forward to your next video. Just subscribed in case I miss it, cheers.
Exactly what happened to mine XC60. The aux belt on my £16,000 fully serviced Volvo snapped, it dropped down and got dragged into the cam belt housing (there's a gap apparently) got caught up in the cam belt and junked the engine. COSTOF REPAIR £3700. Sometime later I was telling someone about it in a pub when a guy leaned across and said it was quite common. He rebuilt engines for a living. He said it was a known design flaw.
Not one for the internal gubbins of engines, but that was interesting to see just how must damage there was done at high speed. Quite a sobering thought really. Thanks lads.
As a retired Design Engineer, I find it incredulous that they would design the Cam Belt cover in this way, leaving it exposed to the Auxiliary belt wrapping and wrecking....A ten dollar saving, but a wrecked engine.... Unbelievable TBH...🤔😳🙄🇬🇧
Yes hearing loss is becoming more prevalent these days, just ask any audiologist. Unfortunately I have a genetic hearing loss, so not self inflicted by raves or loud music. FWIW never let children use the in ear pods.
Lovely car, though it looks like it hasn't had the easiest life. I can't believe how choked with carbon it is for 54,000 miles. I sincerely hope that the damage is only to the head. I'm really looking forward to seeing this progress. Top work. 👍
My old Volvo was from this generation, it was an R design and it was lovely with those nappa leather seats in it, good luck with this. I do like a Volvo and I’ve got a 2018 XC60 now
I don’t know …. Jeez… as someone who’s been involved in Design all his working life … I watch TH-cam videos seeing these modern engines, who comes up with these ideas and who approves them..! I don’t get this at all… but it’s just my opinion I guess…🤷🏻♂️
I've got a V70 R design with exactly the same failure. For some reason, people don't think it's important to change the accessory belt as per the schedule, and just wait for them to snap. You can get a Gates belt for under £20 and it's a 5 minute job to replace. Once I get it rebuilt, I'll probably change the belt every 25k instead of the specified 50k
Some other commentor mentioned an aftermarket device that can prevent the aux belt getting caught up in the pulley. You might want to investigate on that I think.
There is a little device which is available to deflect the aux belt and prevent head damage if the aux belt fails.. but by the looks of it for this one it’s advice a little to late.. good luck guys..
Magic video again fellas your patience and knowledge shines through as usual looks as if it has had a bit of a hard life for the mileage it has done. Stay lucky and healthy looking forward to Saturdays video 📹 already 😊
Just a little tip, the audio in the video is all over the place, by that i mean at one point its so low i can barely hear what you guys are saying so i turn up the volume, next thing i know my speakers are blasting and i wake up my neighbour, so i turn it way down. Then i suddenly cant hear anything again. A normalized volume through the video would increase the quality alot 👍
Well you can't win them all even though I had my fingers crossed. It does look like it was going at speed as you say and would probably just have slowed to a halt once the whole thing 'crunched'. I agree with Chris, investigating a bit more you might find the 'pots' are alright but then as he says what are the prices of a new head V's a new engine? All very interesting content Rob and Chris, we will be looking forward to the next episode. Thank you. 👍👍
We had the auxiliary belt fail on one of these. Changed it plus the tensioner and all was good, thank god we didn't lose the timing belt. All in all it was a fantastic car.
It happened to me also, 2008 V70 D5 136kw, the aux belt was changed 10k ago. Allegedly it happened to previous owner also and the seller fixed everything. So this happened to my current car twice in a 10k km period. Fixed it up but i didn´t change hydrotappets and i left the old camshafts, from this day, my car smokes, has bad fuel economy, vibrates a little too much on idle. Just a sad experience overall since the cars has beige ventilated leather seats, distronic, sunroof etc, all the nice extras you could ever want on a family car. Been looking at other brands but.. i can´t sit in a Škoda after owning a Volvo. Rather a older volvo than a newer cheap-plastic Škoda.
I have 8 x Volvo V70s ranging from standard to a mega tuned V70R. Wonderful cars. If I was allowed to drive that would be the only car I would have. But any Volvo would o.
That's a hell of a design flaw when an auxillary belt snapping can cause all that damage, if mine snaps it would just fall on the floor and allow the battery to drain.
Yep, might even be deliberate because common sense would say but a shield or something in the way so the broken belt just ends up on the road something and not get tangled in moving parts of the engine. Most cars I've seen, no mechanic, the timing belt is pretty well protected from something as simple as this.
@@marksutherland774 Like you I'm no mechanic but know what I'm looking at when it comes to cars and this design beggars belief, I've never heard of the like before. I think I'd be changing the belt every 12k miles/ 12 months as a huge precaution and visually checking it regularly.
@@graemew7001 Yep, insane design, be interesting to see what the service interval is on the belt. As you say, you'd be changing it regularly , IF you knew, most drivers of these vehicles won't' ne the tinkering kind and will only know when this happens.
Doing the same on mine at the minute, Usually happens because of the Alternator pulley seizing, certainly worth replacing, Also make sure you get the correct cylinder head, There's a few different ones, some dont have the engine mount casting and some ahve swirl flaps or don't etc
I had a volvo v70 2.0D 2009 and the auxiliary belt snapped 3 times in 6 years and it was fully serviced every year. Luckily, it didn't cause any other damage.
Hi Guys. Volvo yay!!!Something caught my eye. This could have been avoided, look @10.21 there is a manufacturers fault listed...auxiliary belt!!! Bet this was never changed. Chris's eyes were gleaming as he entered his favourite place, the inside of an engine. Looking forward to the next episode. Loved the chat and discussion between the two of you. Great video. Cheers, Bob
It's a Volvo D5 problem that Volvo seem to ignore, The Auxilliary belt gets worn and starts fraying and the timing belt picks it up and locks the engine, This problem goes back to like 2001 with the first D5's, All Volvo had to do was redesign the timing cover, I've got a 2003 V70 D5 and the first thing i did when i bought it was fit a timing belt kit and a front auxialliary drive belt kit, All new tensioners and rollers! Mine were all clapped out after 236K miles! I now check the aux belt monthly for condition and replace every 20K miles for peace of mind! Apart from this problem they are one of the best diesel engines up there with the Mercedes OM606 IMO!
Biggest problem on these is the Alternator clutch pulley seizing and shredding the belt. Its always vital to put a new pulley clutch on the alternator when doing an aux belt and tensioner service in these D5 engines.
Really good video... even if the outcome was not what we wanted to see. Shocking 'fail unsafe' design there by Volvo. One other thing to bear in mind when you're deciding on what to do is that this SUV isn't ULEZ compliant and that will affect its resale value.
Belt need to be changend every 30 000 kilometars. Good machine shop can weld and drill that head,we do that all time. Need good weld,tight inner diametar and angle of drilling
That's going to be a lovely car. Nice to have a nice long video to watch and it's good to see more in depth like this from time to time when it comes to engine work. Great video as always lads!
Amazing that a broken drive belt can do that much damage to an engine! - doesn't say a lot for the design. Will be intrested to see how you guys deal with this one.
Chris and rob isn't always the same for every car something goes bang and takes out numerous other components! ....no easy fix this time but not a bad track record so far ....but waiting for part 2 in eager anticipation 😊
This happened to mine 200 miles before I hit 200k. Unfortunately it was the AC belt that wrapped itself around the timing belt. Even more annoying is that I just swapped out the timing belt and water pump at Christmas in the snow! So annoying but definitely the best car I've ever had. 2008 V70 d5. I still have it sitting there so depending on how this video goes I might strip the head and take a look, its running but I can hear tapping inside and I think it's down a cylinder, it only happened when idling so I might be lucky and not have much damage. Would be nice to have it driving again so I could reach that 200k!
As already mentioned - shocking amount of damage caused by that belt going. I like that it needs a new head and you guys are utterly not phased... walk in the park for you lads ;) Over to the Rob parts ferret now ;) This is where Rob earns his keep - finding a nice new head for it. Deffo worth saving, as you said - when the engine is back running, that will be a lovely car for someone. PS -that carbon build up !!!! My Q7 is at 58K miles - wonder what lies under the nice engine cover...
I suspect that the pressed on cams is really the least of the issues with that one. There was what could rightly be termed carnage in that head, one can only wonder what else has happened. It will be interesting to see, if any parts went on a destructive journey through anywhere else. The pistons might well suffer a headache after partying with the valves, and the valves might well have suffered. It was not stationary when the fan belt let go, but as for speed, I would not like to estimate that based on so little information. More to come, but more to be revealed I feel, I hope I am wrong. An extensive to-do list is incoming. Have a great Easter break.
Wouldn't touch a volvo with a barge pole, just sold my father in laws 2018 v60. With less than 50k on the clock it cost £1200 to get it through the MOT and that was mates rates. I could provide a list of what was wrong with it but I think it will be easier to list the good bits. 1. The radio works.
@@MadMurdock69 hopefully you never will but I've spoken to several people who had the same model as my father in law and none of them thought it was a good car. Take the MGF, common knowledge that they have head gasket issues but my cousin bought one new in 1997 and still has it, 150k and never had any problems but I think that's an exception.
All them Volvo engines of that code do the head if any sort of timing belt issues breaking the casting the hydraulic lifters we ended up paying a fortune for an engine good luck guys keep the good work up. 👍
Evening guys from our holiday in Brugge and watching another episode of SR 🤣 Fantastic seeing this XCV60 taken apart to see the devastation a auxiliary belt can do 😫 Hopefully you can source the bits cheaply enough for a new episode 🤔 If not Volvo owners watching this Judy might get that auxiliary belt changed before it goes boom 💥 Cheers again guys 👍🏻
My brother had a big Volvo estate and it done had a service history mileage verified by a captain James T Kirk I believe , seriously he sold it on at around200,000 miles
last 2,4 volvo i done that aux belt wrapped the crank timing belt pully got a newer lower mileage engine from a smashed car for the price of a head cams ect worked out cheaper with 90 day warranty so fit and try also been told the crank is likely to twist due to being 5 cyl another reason for full engine the owner well pleased when returned
Very interesting.. I recently had the belts and tensioner done my 40k xc60. Fortunately the old parts were in good nick.. Be nice to see your next video on t rebuild.
As soon as Chris said he could see one of the followers laying in there I thought that the head must be damaged…. Only 54k mile though, seems such a shame!!!
I can't wait to see this Volvo running again. Too bad the engine is a bit boogered up at the moment hopefully you guys can get this engine sorted out.😊
Great video gents love watching the diagnosis and the investigation into what's occurred will make good content rebuilding with a new cylinder head. All the best
Nice detail in vid today, yes that balance between cost for a head and keeping its engine oppose to an 85k miles replacement engine? Nice to get a head👍👍👍👍 🚘🚘🚘
The guy from volvo was right about a poorly serviced car,scheduled servicing would of seen and replaced the aux belt way before it got to the point of breaking,assuming nothing on the aux side had an issue
I am always excited at the start of a new project as I am sure you guys are too. Replacement engine, You will have that organised even before we see the video. Good
@@andyspencer1010 Service history is only as good as the guys that do the service... Mother's '01 VW Polo, bought new, had full SH at the dealership. 11 months after service w/ 1st cambelt change it broke the cambelt. Contacted the dealership for them to take care of it - they declined to take it in...WTF? Got it to another authorized VW shop that fixed it and had words with the Swedish main agent. Ended with no cost for us. Though I don't know exactly what had happened neither to the engine/cause, nor the repair bill, I think something that should've been done at that service/belt change, wasn't...
Same thing happened to my 2.0D3 , I found a good company online based in Truro that recondition the heads on an exchange basis. I think the whole job cost me 1500-1600 £ (i did the work myself) which is nothing considering what a good car they are . I know change the accessory drive belt every service and tensioner every 3rd service. To be fair to Volvo it was a cheap belt that failed I bought from kwickfit one Sunday afternoon when every over parts place was shut , it only lasted 6 months, now I only fit Gates belts.
After getting my car back, I was under the O/S front wheel for steering rack gaiter and noticed grease that would have been thrown out from the driveshaft boot. Boot was OK but my theory is that grease got on the aux belt and that rotted it. Car is 115K and decent condition but I am working my way around some iffy maintenance. Fancy putting a new boot on and leaving gobs of grease everywhere. Pads and discs done all round transformed some judder. Putting poly bushes in now, starting at the rear.
Loved this video. Bought an 2005 xc90 with 121000 on the clock the old d5 euro 3 engine. Done the drive belt tensioner brand new alternator timing water pump new battery and tell u what what a lovely engine purrs like a kitten also run it on vpower
My wife what’s me to get a XC60 and now I know what to look for, would love this one, But steering wheels on the wrong side, for France.will be looking forward to the rest of the repairs.
I had a Renault 1.9 diesel and my belt snapped twice and took out the cam belt both times. Renault has a system where the cambelt has a built I. Allen key which snaps to protect the valves.
All the followers decided to unfollow, not like yours. Another cracking, informative investigation video guys. Love the way Chris approaches and diagnoses these.
Wouldn't worry about offending Volvo. I think it's offensive that an auxiliary belt failure could destroy an engine 😂
It's criminal, bad design flaw 👍
Especially with low miles volvo should replace it
Absolutely! Couldn't believe it at first when I heard that, thought it was still the 1st for a minute.

@@mondodaftasabrush Yes they re-weld and re-machine the head, check the cams, rockers, tappets etc and fit replacements if required and ship it out with UPS which is 1-2 day delivery. They also call you up and give you tons of fitting & parts advice without having to ask. I used them last year and they were the smoothest part of the repair process. The price is plus VAT and they waived the core charge despite never dealing with me before, all they asked was that the head was packaged as they sent it and to call them when it was ready to collect.
The reason I drive bangers. No value no obligation. Old luxury German cars are well made and surprisingly reliable
Amazed that a failing auxiliary belt caused that much damage. If it had been the cam belt it would be more understandable. Thanks for another interesting video. Good luck with getting another head at a viable price. It looks like there are recon ones out there.
Interesting video, as an XC60 owner who has replaced my belts and pulleys at 100k(all Volvo parts fortunately), I look forward to seeing how this pans out. Had never heard of this scenario before, looking forward to your next video.
Just subscribed in case I miss it, cheers.
Exactly what happened to mine XC60. The aux belt on my £16,000 fully serviced Volvo snapped, it dropped down and got dragged into the cam belt housing (there's a gap apparently) got caught up in the cam belt and junked the engine. COSTOF REPAIR £3700. Sometime later I was telling someone about it in a pub when a guy leaned across and said it was quite common. He rebuilt engines for a living. He said it was a known design flaw.
Yes the design flaw is the lower cam pulley is a floating pulley 😮 99% of vehicles have a woodruff key. Poor engineering from volvo 👎
The main problem can be found on the rear tailgate if you know where to look, it says "VOLVO".
Not one for the internal gubbins of engines, but that was interesting to see just how must damage there was done at high speed. Quite a sobering thought really.
Thanks lads.
As a retired Design Engineer, I find it incredulous that they would design the Cam Belt cover in this way, leaving it exposed to the Auxiliary belt wrapping and wrecking....A ten dollar saving, but a wrecked engine.... Unbelievable TBH...🤔😳🙄🇬🇧
Chris/rob... You really don't need to get to uptight worrying about the sound all the time , it's all good...some people must have hearing issues lol
Yes hearing loss is becoming more prevalent these days, just ask any audiologist. Unfortunately I have a genetic hearing loss, so not self inflicted by raves or loud music. FWIW never let children use the in ear pods.
Lovely car, though it looks like it hasn't had the easiest life. I can't believe how choked with carbon it is for 54,000 miles. I sincerely hope that the damage is only to the head. I'm really looking forward to seeing this progress. Top work. 👍
My old Volvo was from this generation, it was an R design and it was lovely with those nappa leather seats in it, good luck with this. I do like a Volvo and I’ve got a 2018 XC60 now
I don’t know …. Jeez… as someone who’s been involved in Design all his working life … I watch TH-cam videos seeing these modern engines, who comes up with these ideas and who approves them..! I don’t get this at all… but it’s just my opinion I guess…🤷🏻♂️
I've got a V70 R design with exactly the same failure.
For some reason, people don't think it's important to change the accessory belt as per the schedule, and just wait for them to snap.
You can get a Gates belt for under £20 and it's a 5 minute job to replace.
Once I get it rebuilt, I'll probably change the belt every 25k instead of the specified 50k
Some other commentor mentioned an aftermarket device that can prevent the aux belt getting caught up in the pulley. You might want to investigate on that I think.
Car surgeons is what you are! Fascinating! Too much to go wrong in these space-age engines. Manufacturers cutting costs?
There is a little device which is available to deflect the aux belt and prevent head damage if the aux belt fails.. but by the looks of it for this one it’s advice a little to late.. good luck guys..
Hi, do you have any details of that device?
Magic video again fellas your patience and knowledge shines through as usual looks as if it has had a bit of a hard life for the mileage it has done. Stay lucky and healthy looking forward to Saturdays video 📹 already 😊
Always good to see you discovering the problems and deciding which way to fix them. Thanks for your work and time.
Defective design, cheap short cuts in manufacturing. All brands do it !
What a great filming rob and Chris just show you what a rubbish Volvo engine with auxiliary belt can do
Just a little tip, the audio in the video is all over the place, by that i mean at one point its so low i can barely hear what you guys are saying so i turn up the volume, next thing i know my speakers are blasting and i wake up my neighbour, so i turn it way down. Then i suddenly cant hear anything again. A normalized volume through the video would increase the quality alot 👍
Well you can't win them all even though I had my fingers crossed. It does look like it was going at speed as you say and would probably just have slowed to a halt once the whole thing 'crunched'. I agree with Chris, investigating a bit more you might find the 'pots' are alright but then as he says what are the prices of a new head V's a new engine? All very interesting content Rob and Chris, we will be looking forward to the next episode. Thank you. 👍👍
If I’m not mistaken you can fit a plate to stop aux belt going around crank pulley. Can be bought as a kit I believe.
I would say Volvo should recall and fit these plate if there is a kit that would prevent this from happening.
Some other commenter mentioned a kit for a cost of around 15 pounds.
We had the auxiliary belt fail on one of these. Changed it plus the tensioner and all was good, thank god we didn't lose the timing belt. All in all it was a fantastic car.
Look at the carbon build up on just 50000 miles! Unreal modern emissions systems!
Glad that both belts were changed early on my 15 XC60 which was on 80k.
If there's ever a car that needs SR-UK love... .it's that Volvo
Great video guys 👍
It happened to me also, 2008 V70 D5 136kw, the aux belt was changed 10k ago. Allegedly it happened to previous owner also and the seller fixed everything. So this happened to my current car twice in a 10k km period. Fixed it up but i didn´t change hydrotappets and i left the old camshafts, from this day, my car smokes, has bad fuel economy, vibrates a little too much on idle. Just a sad experience overall since the cars has beige ventilated leather seats, distronic, sunroof etc, all the nice extras you could ever want on a family car. Been looking at other brands but.. i can´t sit in a Škoda after owning a Volvo. Rather a older volvo than a newer cheap-plastic Škoda.
usually breaks the tappets out of the casting in the head.... head can be repaired by few different uk companies
Very common on diesel engines but also some 2.5T/FT engines have been reported. There is a 15$ kit you can buy to prevent this to happen.
His old ,V70 at 200,000 still went like a "two bob rocket" even at that advanced mileage, only major expenditure was a new radiator I seem to recall
I have 8 x Volvo V70s ranging from standard to a mega tuned V70R. Wonderful cars. If I was allowed to drive that would be the only car I would have. But any Volvo would o.
That's a hell of a design flaw when an auxillary belt snapping can cause all that damage, if mine snaps it would just fall on the floor and allow the battery to drain.
Yep, might even be deliberate because common sense would say but a shield or something in the way so the broken belt just ends up on the road something and not get tangled in moving parts of the engine. Most cars I've seen, no mechanic, the timing belt is pretty well protected from something as simple as this.
@@marksutherland774 Like you I'm no mechanic but know what I'm looking at when it comes to cars and this design beggars belief, I've never heard of the like before. I think I'd be changing the belt every 12k miles/ 12 months as a huge precaution and visually checking it regularly.
@@graemew7001 Yep, insane design, be interesting to see what the service interval is on the belt. As you say, you'd be changing it regularly , IF you knew, most drivers of these vehicles won't' ne the tinkering kind and will only know when this happens.
Doing the same on mine at the minute,
Usually happens because of the Alternator pulley seizing, certainly worth replacing,
Also make sure you get the correct cylinder head,
There's a few different ones, some dont have the engine mount casting and some ahve swirl flaps or don't etc
Chris gives Rob permission to waffle and poor old Rob couldn't think of anything to say.
I had a volvo v70 2.0D 2009 and the auxiliary belt snapped 3 times in 6 years and it was fully serviced every year. Luckily, it didn't cause any other damage.
Really enjoyed this Chris and Rob - love this inspection/fault-finding content. Thank you.
Hi Guys. Volvo yay!!!Something caught my eye. This could have been avoided, look @10.21 there is a manufacturers fault listed...auxiliary belt!!! Bet this was never changed. Chris's eyes were gleaming as he entered his favourite place, the inside of an engine. Looking forward to the next episode. Loved the chat and discussion between the two of you.
Great video. Cheers, Bob
I have the exact same car...I've named it Whack a Mole. Every time we solve one issue with it, another one pops up 🙈
It's a Volvo D5 problem that Volvo seem to ignore, The Auxilliary belt gets worn and starts fraying and the timing belt picks it up and locks the engine, This problem goes back to like 2001 with the first D5's, All Volvo had to do was redesign the timing cover, I've got a 2003 V70 D5 and the first thing i did when i bought it was fit a timing belt kit and a front auxialliary drive belt kit, All new tensioners and rollers! Mine were all clapped out after 236K miles! I now check the aux belt monthly for condition and replace every 20K miles for peace of mind! Apart from this problem they are one of the best diesel engines up there with the Mercedes OM606 IMO!
It must be great to be that knowledgeable and wise! (If they’re that problematic what attracts you to them Scotty?) 🤔
Biggest problem on these is the Alternator clutch pulley seizing and shredding the belt. Its always vital to put a new pulley clutch on the alternator when doing an aux belt and tensioner service in these D5 engines.
Brilliant episode lads...I love the "We'll all have a look together" ones...Spot on content....10/10👌
Really good video... even if the outcome was not what we wanted to see. Shocking 'fail unsafe' design there by Volvo. One other thing to bear in mind when you're deciding on what to do is that this SUV isn't ULEZ compliant and that will affect its resale value.
Auxiliary belt snapped on my XC60 two weeks ago. I was lucky there was no other damage!
Belt need to be changend every 30 000 kilometars. Good machine shop can weld and drill that head,we do that all time. Need good weld,tight inner diametar and angle of drilling
Unbelievable that an auxiliary belt does this much damage. Shared this with a Volvo Owner who has the 2.4 Diesel engine. Great video chaps. Thanks
Getting into the nitty gritty of the job ,love watching you digging around and coming up with a plan 👍👍👍👍
more videos like this please, looking forward to the next one on this. 👍👍
That's going to be a lovely car. Nice to have a nice long video to watch and it's good to see more in depth like this from time to time when it comes to engine work. Great video as always lads!
Amazing that a broken drive belt can do that much damage to an engine! - doesn't say a lot for the design. Will be intrested to see how you guys deal with this one.
The aux belt has a change interval of 5 years or 54k miles. I’d bet money it either wasn’t done or someone has used budget parts.
Chris and rob isn't always the same for every car something goes bang and takes out numerous other components! ....no easy fix this time but not a bad track record so far ....but waiting for part 2 in eager anticipation 😊
This happened to mine 200 miles before I hit 200k. Unfortunately it was the AC belt that wrapped itself around the timing belt. Even more annoying is that I just swapped out the timing belt and water pump at Christmas in the snow! So annoying but definitely the best car I've ever had. 2008 V70 d5. I still have it sitting there so depending on how this video goes I might strip the head and take a look, its running but I can hear tapping inside and I think it's down a cylinder, it only happened when idling so I might be lucky and not have much damage. Would be nice to have it driving again so I could reach that 200k!
As already mentioned - shocking amount of damage caused by that belt going. I like that it needs a new head and you guys are utterly not phased... walk in the park for you lads ;) Over to the Rob parts ferret now ;) This is where Rob earns his keep - finding a nice new head for it. Deffo worth saving, as you said - when the engine is back running, that will be a lovely car for someone. PS -that carbon build up !!!! My Q7 is at 58K miles - wonder what lies under the nice engine cover...
🤣😂 parts ferret - love it.
I suspect that the pressed on cams is really the least of the issues with that one. There was what could rightly be termed carnage in that head, one can only wonder what else has happened. It will be interesting to see, if any parts went on a destructive journey through anywhere else. The pistons might well suffer a headache after partying with the valves, and the valves might well have suffered. It was not stationary when the fan belt let go, but as for speed, I would not like to estimate that based on so little information. More to come, but more to be revealed I feel, I hope I am wrong. An extensive to-do list is incoming. Have a great Easter break.
Wouldn't touch a volvo with a barge pole, just sold my father in laws 2018 v60. With less than 50k on the clock it cost £1200 to get it through the MOT and that was mates rates. I could provide a list of what was wrong with it but I think it will be easier to list the good bits.
1. The radio works.
I've got a v40 d2 and have never had a issue..
@@MadMurdock69 hopefully you never will but I've spoken to several people who had the same model as my father in law and none of them thought it was a good car. Take the MGF, common knowledge that they have head gasket issues but my cousin bought one new in 1997 and still has it, 150k and never had any problems but I think that's an exception.
Replacement head then egr / dpf delete remap and good for some miles , love it when Chris and Rob pull engines apart.
That’s a cylinder head no more 🤦🏻♂️, great vid 👍
No wonder that engine wasn't running! I love a good engine rebuild and thank heavens the Volvo has ended up with you two - you can fix anything!
All them Volvo engines of that code do the head if any sort of timing belt issues breaking the casting the hydraulic lifters we ended up paying a fortune for an engine good luck guys keep the good work up. 👍
Evening guys from our holiday in Brugge and watching another episode of SR 🤣 Fantastic seeing this XCV60 taken apart to see the devastation a auxiliary belt can do 😫 Hopefully you can source the bits cheaply enough for a new episode 🤔 If not Volvo owners watching this Judy might get that auxiliary belt changed before it goes boom 💥 Cheers again guys 👍🏻
Raining there as usual I guess?
had a beautiful experience having a volvo for a weekend . but that rocker issue should be sorted . well done guys
My brother had a big Volvo estate and it done had a service history mileage verified by a captain James T Kirk I believe , seriously he sold it on at around200,000 miles
last 2,4 volvo i done that aux belt wrapped the crank timing belt pully got a newer lower mileage engine from a smashed car for the price of a head cams ect worked out cheaper with 90 day warranty so fit and try also been told the crank is likely to twist due to being 5 cyl another reason for full engine the owner well pleased when returned
Very interesting.. I recently had the belts and tensioner done my 40k xc60. Fortunately the old parts were in good nick.. Be nice to see your next video on t rebuild.
As soon as Chris said he could see one of the followers laying in there I thought that the head must be damaged…. Only 54k mile though, seems such a shame!!!
You hit the nail on the head, if you don't service them your asking for trouble the money you save in the end far outweighs the cost.
I can't wait to see this Volvo running again. Too bad the engine is a bit boogered up at the moment hopefully you guys can get this engine sorted out.😊
Great video gents love watching the diagnosis and the investigation into what's occurred will make good content rebuilding with a new cylinder head. All the best
Nice detail in vid today, yes that balance between cost for a head and keeping its engine oppose to an 85k miles replacement engine? Nice to get a head👍👍👍👍 🚘🚘🚘
Going to be interesting! Sealy make a really good heavy duty plastic step, perfect for reaching into the engine bay when you need more height!
The guy from volvo was right about a poorly serviced car,scheduled servicing would of seen and replaced the aux belt way before it got to the point of breaking,assuming nothing on the aux side had an issue
I am always excited at the start of a new project
as I am sure you guys are too. Replacement engine,
You will have that organised even before we see
the video. Good
You can buy a cheap after marked gadget who prevent the aux belt to go in to the timing belt when/if the aux belt break
Would you like to put on a link for this? I've never heard of one.
Even cheaper check it and replace it
Winds me when ppl don't service there motor's absolute tanks them Volvo's as well see ya Saturday guys 👌👌👌
It has service history
@@sruk oh I thought it didn't my bad 👌
@@andyspencer1010 Service history is only as good as the guys that do the service...
Mother's '01 VW Polo, bought new, had full SH at the dealership. 11 months after service w/ 1st cambelt change it broke the cambelt.
Contacted the dealership for them to take care of it - they declined to take it in...WTF?
Got it to another authorized VW shop that fixed it and had words with the Swedish main agent. Ended with no cost for us. Though I don't know exactly what had happened neither to the engine/cause, nor the repair bill, I think something that should've been done at that service/belt change, wasn't...
What ashame but atleast you got to bottom of it and now know what needs replacing 👍🏽👍🏽👍🏽
Same thing happened to my 2.0D3 , I found a good company online based in Truro that recondition the heads on an exchange basis. I think the whole job cost me 1500-1600 £ (i did the work myself) which is nothing considering what a good car they are . I know change the accessory drive belt every service and tensioner every 3rd service. To be fair to Volvo it was a cheap belt that failed I bought from kwickfit one Sunday afternoon when every over parts place was shut , it only lasted 6 months, now I only fit Gates belts.
I used that outfit, Ian was very helpful. My C70 did exactly the same thing. Autotech cylinder heads.
After getting my car back, I was under the O/S front wheel for steering rack gaiter and noticed grease that would have been thrown out from the driveshaft boot. Boot was OK but my theory is that grease got on the aux belt and that rotted it. Car is 115K and decent condition but I am working my way around some iffy maintenance. Fancy putting a new boot on and leaving gobs of grease everywhere. Pads and discs done all round transformed some judder. Putting poly bushes in now, starting at the rear.
Loved this video. Bought an 2005 xc90 with 121000 on the clock the old d5 euro 3 engine. Done the drive belt tensioner brand new alternator timing water pump new battery and tell u what what a lovely engine purrs like a kitten also run it on vpower
My wife what’s me to get a XC60 and now I know what to look for, would love this one, But steering wheels on the wrong side, for France.will be looking forward to the rest of the repairs.
Good work gents, looking forward to your next video on this motor
Working on my old Ford Cortina 1600cc Kent engine as a kid back in '70s I wouldn't have been able to do any of this modern stuff
I had a Renault 1.9 diesel and my belt snapped twice and took out the cam belt both times. Renault has a system where the cambelt has a built I. Allen key which snaps to protect the valves.
A bit unfortunate that the engine is damaged, but what a learning experience in this video. Hope there is an economic solution.
All the followers decided to unfollow, not like yours. Another cracking, informative investigation video guys. Love the way Chris approaches and diagnoses these.
no just not how it was you lot are just to weak to say wots no your mind life
Really enjoyable, like the in-depth approach, like a murder mystery, how did it happen, keep it up your going from strength to strength
Very interesting project - hope you will show us the whole repair in detail.
Great Ep boys, lovely to see the diagnosis going on during the breakdown.....looking forward to the next one.
I’m not a mechanic but this was absolutely fascinating 👍
