There are some great videos of this service on RUclips. This is the most concise in my opinion. Thank you so much. I will be attempting this on my XC70 this weekend. Cheers.
Excellent video. A couple of other considerations/tips for this job. Volvo reccs replacing the timing belt and acc belts every 80k miles ( you can probably get away with waiting up to 120k). If either has oil on it or have cracks or other signs of wear, then do replace both. Do a visual inspection of the camshaft seals behind the two cam pullies to identify any oil leaks, and replace them if you notice oil. This will require you to first line up all three timing marks on the crank and cams, scribe a line on the cam pullies and the cams so they can be replaced in the same exact position, and then remove the two pullies. Also mark the position of the VVT hub. Then, using a T-55, remove the oil cap on the hub, then the bolt beneath that, and then remove it to access the camshaft seals. Drill a small hole in each seal and run a screw in to be able to pull the seals out, then replace them by applying a thin coating of oil on the new seals and then press them in. Volvo sells a tool to allow you to press the new seals in to the correct depth. Also inspect the VVT hub bearing to make sure it spins freely and doesn't have too much play in it. If it does, or it's got more than a 160k miles on it, then replace it with a new one. There are two kinds of VVT hubs; one kind is soring loaded, the other not. If yours is spring loaded, then it is very important to rotate it two pully teeth to properly allow for the spring to tension and time properly. There are videos about how to do this properly on YT. This may seem like a daunting job, but it's really not all that difficult.
FYI . At 26 minutes and 20 seconds (you say it backwards). The CRANKSHAFT rotates 2 revolutions to the CAMSHAFTS 1. Not the other way around. Hence, the cam gears are twice the size as the crank gear. Other than that, VERY GOOD VIDEO!!! Good job...
From what I have heard, the timing marks do NOT equal top dead Centre. It is a point where no piston is at the top of the cylinder at all, because of this you are able to rotate a camshaft 360° without damaging the valves. Hope this helps.
Thank you for sharing this video, is the most clearest video I've ever watch a step by step how to change a timing belt. All the question in my mind I found it here. Thank you once again.👍👍👍
This is a wonderful video. Just wondering if it is totally necessary to remove the harmonic balancer? I've sen other videos where they don't do this during the timing belt change. Any comments are appreciated, thanks.
Hi. I've just finished renewal of timming belt, tensioner, hydraulic gizmo and roller. Serp belt. I've worked on all makes of cars over the last 45 years and I can honestly say this was a pig of a job to do. As we know cars are not made for home mechanic maintenance these last thirty years. The main problem on volvo 850 petrol engine is the belt is almost impossible to fit with balancer in place. It's also impossible to get cam pulleys lined up once the pin is removed from the hydrolastic piston. They move back one tooth off the mark after two rotations of crank. Therefore you have to outsmart the car by carefully turning both cam wheels one tooth to the right, towards the front of the car, in order to have all notches lined up after pulling the pin! This I've found out by bitter experience. I must say I had the same problem on my mgf after HG renewal last year. Well, I hope this helps anyone out there facing the same job. Allow at least six hours to complete the job. Great learning curve!!
Be careful guys with the exhaust camshaft pulley with vvt system as in this video, because it can rotate the pulley and it can confuse you with the marks. You believe that all in place and you did not notice that when you take off the belt the vvt system move the polley one or more tooth; here it is the raison because there is a tool that blocked the cams in their opposite sides. It has happened to me that despite putting in marks before removing the old belt, once I removed it I did not realize that the VVT system moved a single tooth backwards, which in the video does not indicate that this can happen. Sincerely, after the installation and check the marks i had doubts, it seems that it was a tooth deplaced but it was difficult to differentiate because the angle of vision when you do it with the engine in car. In adition, all was in the same place (or i believe) before removeing the old belt. Well, honestly, I still don't understand what happened, but thank goodness that when starting up I hear noise and stop the engine immediately and I can realize this. I didn't understand anything, the marks were in place, nothing had moved during the belt installation process, the polleys were in the same position before removing the old belt,... but it had and I realized when I took the belt out again that I saw how the pulley moved back a tooth by itself. I had to rotate clockwise this cam one lap until arrive and the correct mark. In short, guys, be very careful with the vvt system and watch other videos about how the change is made with this system.
8:00 Haynes manual says that "The crankshaft sprocket flange rib should align with the oil pump housing mark". That rib is only visible after you remove the crankshaft pulley. I absolutely can't see the 2 marks that you describe here. I'll try to clean it up a bit better.
Why would I need to hold the crank shaft in place to do it by hand but not with the gun? I want to attempt this at home but don’t want to damage my engine
i pour Coolant in the reservoir as the engine is turned on but its not flowing down So the reservoir just fills up and thats it My car overheats after 5 minutes of driving! Does that mean that the water pump is bad? Because radiator is not clogged I already passed water from side to side of the radiator and it flows through Any body please help im new to Volvos

How did it go?
8:52 with a slight tap of a rubber mallet (proceeds to smack the snot out of it) 😉
Great video! Helped a lot.
Thanks! Incredibly clear video work and complete directions!!!

Man, thank you! You make everything looks so easy! You explain so well that even a person with rudimentary technical skills could handle it!

thanks allot for this video!! i changed timingbelt and waterpump on my v70 2.4t 2002 yesterday and this video was just what i needed
This is a wonderful video. Just wondering if it is totally necessary to remove the harmonic balancer? I've sen other videos where they don't do this during the timing belt change. Any comments are appreciated, thanks.
Great video! The temperature varying tension system and also the interference engine design make me reluctant to DIY. I guess I have to pay the shop.

Excellent tutorial for a project I have soon. That said...did you break the tab off the coolant bottle?
Very good filming,it is a really close space impressed
Multumesc frumos pentru informații și va doresc tot binele din lume mitică
Thank you for that video! Just bought a V70 and this will be very useful :D

Use a solvent to take off the leftover gasket material. Gasoline, acetone or isopropyl alcohol work great to remove that.

Very thorough very professional and clear
Thanks for this excellent content. Will be attempting this on my 2008 S60.
Great video. What are the torques on the harmonic balancer: 10 mm nuts and 30 mm nut?
Best video on youtube
Great video. I used it while attempting the belt change today. And with this tutorial all went well
I changed oil for 2001 volvo v70. Thanks. Garage asked me for 285 euros. I did for 100 euros.
❤ you are an excellent professional maintenance and repair a best guild line for me
outstanding video my man!
Brilliant Video
Very good video. You explained everything!!
+@ggtaruc2578 Thanks for watching our video! 1aau.to/m/Shop-TRQ
11:12 why i cant just release the tension by pulling that ”lever”? Whats wrong about it?
Is this for a diesel or petrol ? Or is the application same for both.
exactly what engine are you working on? my 2006 xc70 2.5L turbo 5 cyl. looks similar but does not look exactly like what you have there.
Legend❤
What is the manufacturer's recommendation for change interval time and kilometers?
Super, dziękuję za film. 👍Pozdrowienia :)
very good video,very clear .
The crank turns twice to every turn of the cam shafts. This guy has it backwards.
bloody brilliant, thanks . 😀
Do I need to buy a Cam lock to do this on a turbo xc70 2004?
What size is to take off the middle bolt for the crankshaft?
26:20 "cam turns twice around as crank turns once". I think you go this backwards
I agree very well done.
Why would I need to hold the crank shaft in place to do it by hand but not with the gun? I want to attempt this at home but don’t want to damage my engine
Sehr gutes Video! Herzlichen Dank für deine Arbeit.
Kennst du ein Diagnosegerät für meinen Volvo S40 I, 1999, Benzin, 85 KW (9101/722)
You broke the outer clip for the coolant reservoir at 29:32
Does this also apply to the VVT engne?
+@MN-id2cl The repair should be the same or similar for the VVT engine.
Extraordinary detail !
Super helpful !!
I learned lots !!!
Thanks mate .
👊🏼 🔥 🧰 🎯
+@ThunderbirdRocket Thanks for watching our video! 1aau.to/m/Shop-TRQ
nice job
Do you really have to take the crank pulley off? Cant you just loop the belt over it?
Two rounds of the crankshaft to one round of the cams.
Tenho uma volvo desta, estou com dificuldades de comandar.
Awesome
i pour Coolant in the reservoir as the
engine is turned on but its not flowing
down
So the reservoir just fills up and thats
it
My car overheats after 5 minutes of
driving!
Does that mean that the water pump
is bad?
Because radiator is not clogged
I already passed water from side to
side of the radiator and it flows
through
Any body please help im new to
Volvos
