More PROBLEMS?! (Part 3 XC90: Start-Stall, Low BOOST?)
Вставка
- Опубліковано 1 жов 2024
- Just when I thought we were almost done with this Volvo XC90, it starts throwing curve balls left and right...
The car needs to be RELIABLE to drive back 7 hours to VA, so we have to sort out these issues:
1) Start-Stall after 10 seconds
2) Crooked Steering wheel and ABS codes
3) Crankcase Pressure Check
4) LOSS OF BOOST: Turbo Performance
5) Weak Battery
6) Leaking Axle Seal

Wow, another Volvo coming up? At least we know it will be a three-part series. 😂 Great videos Ivan!!
Too bad they're all modern....
Maybe he'll get a 90's rear drive Volvo in some day, those are my favorite... I love those cars.
@flatdaddio, I guess this is why my brother's wife had said their Volvo spent more time in the shop than on the road!😂Thankfully they got rid of it long ago. Idk who these people are who "design automobiles" but I wish they'd stop and go back to simpler designs if they can't utilize "newer technology" without over-complicating it, making it massively expensive to repair and decreasing longevity. I remember back when vehicles coming out were said to "be able to wait 100,000 miles before the first 'tune-up' " yet in the last 20 yrs we have vehicles that experience major engine/transmission problems/failures in less than 100,000 to 150,000 miles, although some have managed to double that... But then there have been some vehicles from the 50's/60's which with proper maintenance have remained in operating exceeding 500,000 and in some cases, 1,000,000 miles. I'd like to see the stats on the percentage of "repairs" and "inspection failures" drivers experience which are ALL related to "emissions system components" whether those are internal or external to the engine/drivetrain.
Ivan is one hell of a mechanic! I worked at the dealer when these were brand new and i gave up and got out of the business! They were plagued with so many problems i could write a book and start a youtube channel haha. Bottom line: If ivan has to put this much effort into saving these, what chance does the average shop have. Answer: none
Yeah these 1st gen XC90s really are money pits lol
Only answer I say, get Ivan’s earned college education.
@@SocketSilver That wouldn't be a Silver Bullet, cough cough SocketSilver.😂
I am not sure how other AWD systems work like my wife's 16 RAV 4. This design on the Volvo is crazy...there is an extreme potential for cross contamination of fluids. Having a seal to keep fluids apart...wtf was the engineering team thinking???
I know AWD and turbos make for a great car to drive. I am no fan at all of turbo charged engines. When Toyota ditched the 5.7 v8 for the TTV6, I pounced on my 20 Tundra. As for AWD/4WD there are better designs and some that are not so good. I find it amazing that replacing a rear main seal lead to so many problems. I even wonder if trained Volvo techs have the knowledge to do proper repairs. Thankfully I am a poor working guy who will never afford anything European.
Wow! After repair of the original complain, there were more unrelated problems - if only that original seal replacement had been done with care. Great job Ivan!
Seems the beached whales found the way to your shop :-) Curious to know about the next Volvo.
I'm absolutely amazed a car which is regarded in europe as being built like a Brick S - - t house should have such a weak component in its rear suspension. I am more used to seeing that gauge of metal in photocopiers and printers that I used to work.
Uilt
Welcome to Pine Hollow Volvo Diagnostics - I'm your host Ivan the Terrible of the Pennsylvanian Rus and today I will do battle with 4 wheeled Swedish demons!
The tail of two Volvo's it was the worst of times
Ivan, the Harbor Freight pneumatic brake bleeder is less than $20, and would save you so much time in sucking out fluids from transfer cases/reservoirs
It's not the best at sucking brake fluid out of bleeders, but it's great for jobs like that transfer case
I use it all the time to quickly empty a power steering fluid reservoir when changing fluid, or sucking a master cylinder dry before a power bleed procedure
I actually have one and use it regularly. I lower the compressor output pressure to 20psi to prevent cavitation of the brake fluid and micro bubbles which form large air pockets. I also use it for extracting other petroleum-based fluids.
That transmission/multiple seal setup is very similar to the AWD Mitsubishis of the 90s and 2000s, however I've not seen one fail. Less of an issue even if it happened on the manual gearboxes as the fluid differences are basically GL-4 vs GL-5 and that's it.
I predict a lot more Volvos are heading your way. No one else wants to work on them
Ivan is the "volvo king" and beached whale harpoon master
Foreign speaking drivers are transporting Volvos to Pennsylvania right now! lol
Lmao
He's always fixing problems caused by shoddy 'skinwalker' mechs.
The ATF mix with Axle fluid really blow my mind! Ivan, thanks for the sharing this Volvo trick!🙄
Car lot brought me 3 gm 2.4 timing chain jobs in 1 week. They called on Thursday and asked about doing timing on a silver Malibu. I said I just did that one Monday. They said not it's another silver Malibu 😂😂
If the 2.4L is anything like the 2.2L, they will go a million miles with no complaint despite any mechanical noise or lack of oil. The 2.2/2.4 ecotec is the Ford 300 of our generation.
@@RK-kn1ud No they are not even close bud. any Gm 4 or 6 cyinder 3.6 or 2.4 are some of the worst engines made
Just wait until these EV Volvos start having problems….
this what happens when you take a gm part and modify it to a volvo design you impressed me of your knowledge of how the gear system worked
Yeah, how to turn a FWD transmission into an AWD platform, haha
I bet at the time, Volvo engineers where high fiving each other after coming up with that transmission design 🙄
Just because you can build something a certain way doesn't mean you should.
Volvo Groundhog Day. What are the chances of that happening twice ? You think you've seen it all. Nope
Ivan you are realy one heck of a tech..dont seems to quit on job..😊congratulations on successful repairs..cheers
I worked at volvo too they sold out to China and all the goods moved to trucks and heavy equipment. !!!
I hope more Volvos come in ! Enjoying this Volvo diag content! 🇸🇪
You have a REAL Volvo as your profile picture!
Pine Hollow Volvo Repair, has a twisted ring to it...At least it is not a BMW.
I'm surprised to see such a wimpy track bar on a Volvo
Great work on your part believe I will stay away from those cars
The output shaft seals on 4x4 ford's fail and the transfer case will eat 3 qts of transmission fluid. It always boggles folks when they have to add transmission fluid and there are no external leaks.
Who is the guy that is always talking about these endless money pits again? What is he name again? I bet he will say: I told you so!
The Steering Angle Sensor (SAS) is one of the more common causes of the "Anti-Skid Service Required" error messages the other main problem being the yaw sensor. I had the same message on my own XC90. The problem was the module for the Haldex on the rear diff (DEM). It was beyond repair so I had to get a reconditioned DEM costing just over £300. My Central Electrical Module (CEM) would also quit after about 3 hours of continuous driving. I was able to get the CEM repaired for about £150. Further to what I said about the CCM-0021 error code in Part 1, a genuine Volvo sensor MUST be used. VW makes a smilar sensor which will fit physically but it will cause the Climate Control Module (CCM) to throw a wobbly (it must be wired differently to the Volvo one).
I thought this might go in a different direction.
Broken Volvo XC90 + Broken Volvo XC90 = Working XC90 + Scrap.
So I just watched one of your older videos from 6yrs ago, and this one this morning. Bro bring the beard back hahahaha
Thanks Ivan, my 2000 Grand Cher is looking better by the hour. I've had a couple of Volvos, a 79DL and 81GL when they were much simpler machines. I guess we must accept "progress" these days. Good work. Cheers.
Amazing Ton's of knowledge, Thanks for sharing Bro😍
This series has educated us a lot on Volvo engineering, Thanks to you😍
Looking forward to the next one😍
Stay Safe BRO😍
I can hear the designers at the water cooler: "Hey, let's see how many seals we can have on one axle shaft".
the other designer probably say: "more are better"
"Engineers will walk over a thousand virgins just to fuck a technician"
My brother in law brought one of these, same model same colour Private sale.On the long drive home the money light came on . Got it home Tried to fix it .,couldn't ..Had others try, no luck .In the end he lowered the windows ,propped the tail gate open. Took The only thing that was any use out ,that was the battery.Them let his hens move in .Still there today as a hen house..
WOW 😂
Same this, that, and the other thing doesn't surprise me. I remember what seemed like an entire week of deja vu all over again. One day, two identical FJ cruisers came in for an alignment. One just left when the next one showed up. One day was a bunch of Nissans in for tire/suspension work. IIRC, they were all Sentras. One day was two Honda Civics, both loaded with fat Asian families. I'm not picking on fat Asian families, it was just how the day went.
Volvo magnet! Is there a Pine Hollow Euro Diagnostics channel in your future?
GM 4x4 transfer cases have the same idea with seals in keeping the transmission fluid separate from the transfer case fluid. To replace that seal, its an easy fix by removing the transfer case and that seal is located on the front of the transfer case just behind the trans tail shaft. Its a double seal too, has two seals in one.
Volvo has always been "off" when it comes to logic. People buy those cars because they believe they are "safer" that most vehicles. Problem is they tend to be maintenance prone and for the most part, are rather boring in design. The old Volvo's 1970's and before were very dependable however, they had no style at all.
Those nice friends damaged the turbo nipple and a lot of other things under the hood in R&I that engine. That job should have included a lot of other things "while they had it out" since the customer was planning on keeping the vehicle long term. New hoses, rubbers and other items that age and are hard to get to. Losing critical bolts, nuts etc. is classic for nutjob mechanics, they simply have no consideration for collateral damage when working on other folks vehicles. It all has to go back the way it was, hose routed correctly, secured the same, fasteners need to be saved not lost.
Ivan is becoming one heck of a eurotrash specialist.
Wow you are so gifted! God's gifts and talents are awesome!!!
I wonder about the gear lube in the chain case. In the 1970s, when New Process started using chains in transfer cases on four wheel drive trucks, the chains had a high failure rate in as little as 2 years because the chain got too long and would jump teeth on the gears. New Process figured out that the 90 weight gear oil they were using basically turns to a solid in extremely cold temperatures and didn't provide enough lubrication for the chain. Replacement chains came with instructions to fill the transfer case with ATF behind an automatic transmission or 10 weight oil behind a manual transmission. That change seemed to solve the problem with the chains. Modern synthetic gear lubricants probably don't lose as much viscosity when cold.
Intresting find
Virginia, the 'we don't need trackbars here' state.
The beauty of UA-cam is the evidence is readily available for any customer, proving that he/she is not being conned, as they were in the past by most UK garages.
7:43 By the sound of the track bar, that's a thin piece of metal, plus it has slots taken out of it. Already thin as can be, how much weight did that remove? (if that's why the slots are cut in it) Sheesh!
GL4 is hard to find nowadays, i did a trans swap on a cobalt ss a few weeks ago. Called all the parts stores for Gl4, they tried to sell me gl5, called gm, subie and hyundia dealer cos they had it in stock back when i worked there. No luck, i eventually found redline at OReilly for 25 a quart.
Yup Redline is my go-to :)
I always look up TSBs on a model before I buy it. Some cars, reading the list, you do NOT want that car.
Why do I do that? Yes, I got burned on a 1998 Ford F-150 4.6 2-valve that had the infamous oil leaking from head gasket at about 90k miles.
Ford says they left debris between the block and head during manufacture, and OHC engines have a lot of oil being pushed up through there for OHC lubrication.
Blue Devil fixed it, then I sold it.
At 12 MPG, how could anyone afford to run it?
Yeah it's thirsty... And PREMIUM gas! 😆
T6 is a bad engine/trans combo. The rest is actually fine. Shame you yanks did not get the D5 diesel. Those are mighty fine. Mine is at 367k kilometers right now and running good. The aisin 6 speed auto is also working great. The bevel gear design is way different and cant leak auto fluid into the bevelgear.
Oh yes the D5, i sold mine over 720.000 km to a vriend, he toke it on vacation true Europe and the car is over 800.000 km and stil going.. super engine, luckily my wife's S40 had an D5 to.. almost 400.000 km.. very nice engine with a beautiful sound..
I almost bought one of those xc70 cross country
From used lot at Volvo dealer. But check engine light came on during the test drive. And guy that came with me said quietly AGAIN! Course I heard it and said excuse me?
He wouldn’t repeat himself but swore it would be fixed before I bought it.
Needless to say for $9,500 with 120k miles on at that time a 8 year old car
I passed. Once I figured out how expensive parts were. For simple things
When I went back to college I was subbing my income doing electrical stuff on cars at my buddies shop. One ofv the older more squared off wagons was there. They couldn’t figure out what was wrong with it. It had bern to a few shops. Long story short I figured out the Mass Airflow unit was pooched. I remember it was pretty expensive. That was around 1992-93. Was an interesting vehicle but wouldn’t want to own one.
My Sister had a Volvo. She loved it, BIL said it was fun to drive.....until it wasn`t. His mechanic told him the repairs exceeded the value, turbo issues, massive codes, it` was like the car had a massive stroke. They donated it to a shop class. Their problem now. Oh and it did have blown seals, BIL did not like the stains it left in his driveway.🤣 Wow, yet another Volvo coming?😮
nice video tho I have an 2005 xc70 with 480 ,000 mls and the same issue. the cam ankle seal was leaking and and mixture of . trans fluids and gear oil when it first started. never worked on volvos before until i own one. As a former Toyota Tech. I looked at the problem and put a new remanufactured Transmission , in it and hoping it doesnt have China seals in it. I got the Vehicle with 200,000mls on it and think the previous owner felt for the sales pitch of never worrying about changing the transmission fluids and the fluid was darker Joan of Ark I kinda fixed two problems problems with a new tranny. tho. Thanks for more tips on your videos🖕🤙🤙.
Ivan, Hi I wanted to let you know that it is best not to drive damaged suspension geometry vehicles on small country lanes (A large open racetrack is okay). The damage should be repaired, with alignment checked before test driving. For example, with the rear suspension arm damaged the vehicle can exhibit strange and unpredictable behavior, like stepping out into a spin, with absolutely no warning, in a slight banking turn with brakes suddenly applied.
For the vacuum control actuator repair, you could have used automotive structural adhesive (3M 07333) if you made a ring around the can face with extra support to hold the tube, the ring and tube could be brazed before bonding to the housing. The adhesive once set would also form a seal. The newer automotive structural adhesives are very strong and would not require applied heat like with soldering. However, you would have to fully clean all surfaces to be bonded.
The customer stated that the engine rear main seal was replaced for free? The next question is, who did the work?
The advantage of the large MityVac evacuator pumps (like the MV7201) is the tubes supplied are long and different sized diameters, and once you build a vacuum you can move the tube around with sustained vacuum. For many shops, oil extraction with these pumps are usually assigned one type of fluid (mostly because of oil recycling requirements), that is one for each of, engine oil (which includes heavy gear oil, Transmission Hydraulic Fluid, and finally engine coolant. The advantage of the pumps is you know how much is pumped out, then transfer (pump out) to recycle storage then pump in the required fluid replacement quantity, and finally transfer to the vehicle. If you feel there is a fluid compatibility issue you can do a pre-rinse with new fluid.
The MityVac small diameter hose can fit down the small dip-stick tubes. If you do routine maintenance on a vehicle over time, you can do a transmission fluid swap (pan only) every engine oil change. Just pump out what is in the pan, and replace with the same amount. So you are essentially changing all of the fluid over time without dropping the pan and avoiding a flush. This is a very popular approach if you have access to a dipstick tube. Scotty Kilmer likes this approach and so do I. However, this way of changing transmission fluid over time when you do all the maintenance on the vehicle has a long history, much older than Scotty and myself.
Also, if you have a vehicle that has an automatic transmission shudder on one of the upshifts (3 to 4), or when the TC locks up, you can do this partial fluid swap technique and see if the shudder is reduced or eliminated (you can use the partial fluid change as a way of troubleshooting). If it is reduced, then do the partial swap again after about 10 miles, which many times is enough new fluid to make the shudder go away. Then just do the partial swap every time you change the engine oil. The only time you need to drop the pan (after it is emptied by the vacuum pump to minimize the mess) is to replace the transmission filter. The approach assumes that there is no major damage to the transmission. The attractiveness of the partial swap is it is very fast and inexpensive, you also have the opportunity to use a recommended transmission fluid upgrade (usually synthetic of some type). Once, you start the vacuum process you can let is run on its own until the pan is emptied. Super easy.
Ivan - EVERY video I watch, I'm more and more impressed. - much respect your way.
"Runs like a Raped Ape!" LOL i haven't heard that term since the seventies. good on ya Ivan.
around the same time there was a speed parts company who made things like weaker distributor advance springs called 'S'AAPE! whose logo was an ape completely on fire, running down the street like mad. they were ape! i put 'em in everything i could get my hands on. sure beat trying to take a turn or two off.
Oh today was backwards Monday. Did a transmission in a Chevy Colorado. Broken flex plate and customers attempt repair and installed rear main backwards. 2012 Nissan versa crank sensor melted by exhaust leak. Wires unidentifiable at connector. Oem connector view was 123 and it should have been 321. Come home and water heater blew up. I hate Mondays
Oh yeah sounds like a Monday for sure haha!
Great video Ivan. That issue with the seal sounds like when the seal between the transmission and transfer case fails and you have transmission fluid leaking into the transfer case. You did a great job on this xc90 from HELL and I am sure the customer was happy that he had you Diagnose this XC90 from HELL.
Omg i had a truck come back today for a popping noise. 2 weeks ago I replaced both lower control arms (they came with balljoints already bolted on) come to find out 3 nuts on passenger side came loose and 1 on driver. That is so dangerous iys scary. I've done a ton of these and never had this issue. This China junk is getting way out of had especially dealing with life and death repairs. Imagine this lady doing 70mph on the highway and the lower balljoint let loose
Ugh. Didn't realize, rear main seal repair was "free". Well then owner kinda got what he paid for. Otoh, trans fluid separated from gear oil by an internal seal, as noted, terrible design. That's on Volvo, not the owner. Seems at least this generation Volvo XC90 a good one to avoid.
I guess they make the track bar weak to act as a "suspension fuse" to keep from damaging the more expensive parts.
Interesting theory! I should keep these in stock haha
sWEDES are very complicated individuals, with weird values and ideologies
That’s a real crappy way to separate gear fluid and trans fluid! So if the inner seal starts leaking you won’t know? Til when? U do a fluid change?
Mixing those fluids cuz of a bad seal eventually would damage the transmission wouldn’t it?
Idk what those engineers were thinking seriously..
Wonder how many Volvos transmissions go out all cuz mixed fluids you can’t see til it’s too late 😅
Talking about lost boost
I was on a road trip to the Alps in France in my old 1994 Peugeot 405 TD and I'd just replaced the cam belt and water pump.
I was nearly there and going up a massive hill at about 50mph and suddenly lost power pulled over at the top.
loads of oil smoke was coming out of the engine bay at the same time it sounded like a tractor.
I thought, nightmare I'm 600 miles from home.
Anyway looked in the engine bay and the turbo hose had popped off.
Started it again and now no smoke but still sounded like a tractor, looked underneath the exhaust down pipe had snapped off 😂
Excellent video series. I came away with two things after watching this series. One, stay away from Volvos, two, you need a full size shop with a lift.
I knew a vw mechanic that checked all grounds on vdubs when they came in because they were always suspect. He learned from experience. He even had racks of them premade up to just replace them. Ivan , you are experienced enough to know this. Most may not need replacing , maybe just a good cleaning prior to any diagnostic just for peace of mind.
2004 xc90 t-6...surprised to see there still around. most people give up on them after their second trany goes bad. or the head gasket leaking oil on the passenger side. The older s80 with the same t6 engine is equally as bad
Have the same exact car, bought it with a start problem which eventually caused no crank start, changed the crank position sensor and crank sensor seat with issues. Had to drive for a while without my air mass flow sensor and housing. Ended up cleaning out the ground cables like you did and it solved the problem half of the time. Now waiting for a new crank sensor seat as mine is broken. Can you give me any advice on solving the crank sensor issue? (Bought a brand new crank sensor)
Hi farmer hear my f 150 2010 had a electrical trouble took it to ford no fix they changed a few thing no fix I limp it home spent 2 day finding ground etc all of them I think copper coat my best friend all is well all the test stuff some time you have to go back to basics god bless you keep on keeping on
I'd rather chug a lug arsenic laden tea than own a European vehicle out of warranty. One VW I worked on was overheating due to a plugged heater core. Quirky indeed... and stupid. 🙄
Hey Ivan, I have a 2012 XC90 D5 . Cam sensor issue, very hard start but as soon as it warms up no more starting that day… any tips? Thanks in advance…
I saw I Do Cars also got a Volvo from the auction and he is damn lucky, all it needed was gasoline! I guess it is the Volvo month!
Actually, you should’ve filled it to the cold mark if the vehicle wasn’t warm once a vehicle warms up, it could be over
Man stuff like that happens all the time in a busy shop. One week I changed 3 nissan cam sensors some bank each one. Never changed one before haven't since. Crazy the trends
Hurry up, ship this thing before you find something else that needs fixed. This thing has more problems than my Aunt Millie.
I bet his trunk was loaded heavy and it only take a small pot hole will bend thos rear stablizing bars They come from the factory underbuilt and weak
That track bar seems awful flimsy. Maybe it requires Russian Engineering to strengthen it a bit so it isn't such an easy failure point?
One of my friends had a valve estate auto box it drove in limp mode due to gear box filter blocked cost over 300 UK pounds to replace.
Kudos Ivàn..your just The coolest mr Fix!
Ivan's becoming the Volvo whisperer.
You know what's way stronger than RTV silicon. Shoe Goo.
GM 4T65E transmission that’s why they have issues
Ivan can you fix those chain drive seals if the the owner pays the cost. How difficult could it be? May be a 3g job?
Anything can be fixed... But I might turn down that job haha
@@PineHollowAutoDiagnostics don't blame you for not wanting a seal up job. It is a pain trying to get cars fixed . Lack of parts complicated designs etc. In third world countries they would rip cars apart and rebuild them back better. In usa its not cost effective. Labor cost too much. You helped a lot of people with your skill.
I started watching these videos. This fellow is very sharp ....i watch these to learn
Most European cars suck in terms of design. This video confirms my opinion.
What are you gonna do for the customer then in filling me I want to take it back. Do not recall repair and then shipping.
Extremely stupid design for that head box
Someone tried to jack them both up and the jack bent the control arm seen it many times
You beat me..looks like they jacked it up then rested the control arm on one of those jack stands with a v shaped top.
My guess on that lower track bar is a tow truck hook at some point. Looks like it anyway. Once they bend, they won't have the same strength if straightened plus, its a suspension part, always get new.
What scope are you using. Looks like a neat multichannel setup.
You could try adding AT 205 to both the gear oil and the ATF in order to recondition the bad seal.
Lucas is also a good product
And i thought Break My Wallet was mad :-D
The early S80/XC90 T6 models came with that GM 4T65 and are known to have many issues. Unfortunately the transversed inline 6, twin turbo and AWD wouldn’t allow the Aisin Warner AW55 in all other P2 models to fit. Once there’s debris on the plug, it’s probably not long for this world.
that plug is for the bevel gear/ chain drive, not the transmission.
I had/have a similar issue. My plug looked like that too.
Similar to this owner, I'm just driving it till it essplodes.
Ivan is becoming an Volvo whisperer! Not a bad choice. There are a lot of owners of older Volvos who still are loyal to their cars. Don't ask how I know, owning a 1965 Volvo Amazon B18 4-door. Volvos are not an Porsche or Ferrari, but there are a lot of 0-30 year old Volvos out there without an expert diagnostician / technician, who does not break the bank.
Design of the transfer case shows the desperation of Volvo. Before Ford acquisition, Volvo did not have the money to make an integrated manual / automatic gear box with propeller shaft output. That is why Volvo used standard Aisin Warner automatic and their own manual gearbox. They did not have the money to do anything else than the kludge you saw in this video.
That is why I did not buy the X70, but the V70 model year 2000 with Porsche/Volvo 850 engine and 2 wheel dive. Neighbor offered me an X90 for next to nothing, with an non working 4WD. I refused to dive into a money pit. Audi/VW had the money to have their own gearbox designed for 4WD, Volvo did not and Ford did not give money Volvo to design / produce one.
Makes sense! Weak GM transmission with add-on AWD chain case is not what I expected from Volvo haha
Not a fan of Volvo since I bought a 2010 XC60 back in 2012. 1500 miles past warranty I got a flat tire. Spare tire cable gearbox made two rounds down and then locked up solid, would not turn either direction. Had to cut the cable. New gearbox was over 400 dollars! I traded it a few months later.
Not the worst problem to have but annoying nonetheless lol!
Let me guess, customer brings in a car with a dead battery and a near empty tank of gas.
Haha close!
has some one with a 2 post lift failed to put the pads under the corect places . or per haps somone with a trolley jack
Bottom line, don't let the luber gubers work on the Volvos.
We Europeans, Germans, and others do not consider Scandinavians, Swedes, Europeans. 😂😅😂😅😂😅😂
Even Mercedes and BMW would not make something this complicated.
I did not see on that last diagram how the chain for the transfer case is driven. That axle has no gear or anything to drive the chain. Is there an outer tube that the chain runs on that I could not see there?
I owned a 98 S90 for about 4 years. Not awd.
It drove nice but was a bit of a nightmare to maintain.
Yes hollow shaft that splines into transmission 👍
yep, in the daytime they design super complicated transmission seals, then in the evening they will club a baby seal to death with a lump hammer, pickle it, then eat it 1 year later.... they crazy up there!
Eric (SMA) had a good one with a bad ground between the chassis rail and body.
"Someone has been here before" ... Volvos in the US seem to be plagued by moron mechanics, chinese crap parts and idiots with forklifts. Obviously designed to be worked on by on or above average IQ mechanics that put in and torque all bolts not just which ever they feel like... These cars are solid otherwise.
Looking at the failure rates of the GM-sourced automatic transmissions in the T6 models of this era and that awful AWD-t-case design, Volvo’s engineers are every bit at fault here as well
Thank you Ivan for another informative video.
My pleasure!
imo it's no pleasure to work on a poorly designed car
Me: wouldn't it make sense to rate for chain drive for ATF and have this done with? Engineers: We can increase the complexity by a power of ten and use two fluids--Let's do it!
Would be nice if fluid level was the same too haha
My, oh my! What a train wreck this one turned out to be. Typical though. Not many people know all the ins and outs with Volvo's. Mistakes can and will become very costly. Which is why a lot of mechanic's refuse to work on them. Those T6 XC90's, you have to take very special care when removing and installing the right side axle. Knick that center axle seal and you will certainly regret it. The chain in the offset unit will not last long bathed in transmission fluid. It will literally eat itself alive. And let me tell you, it's a pain to replace that offset unit. Oh man, I kind of feel bad for the owner now. At least it didn't cost the owner anything for the initial damages..... Or repairs? Take your pick. I did enjoy the ride along Ivan. What you had there was a typical day for me at the Volvo dealership I used to work for.
I don't envy you working at a Volvo dealership haha
Volvo leak tsb - the customer spending even more money will surely make them more satisfied with their Volvo. Do they have another tsb that says while you have the transmission out the second time to get it to ground to the engine, you might as well change all these seals that will never seal again once it was apart?
