How to: Volvo C30 S40 V50 C70 T5 Serpentine Belt & Tensioner Replacement
Vložit
- čas přidán 5. 07. 2018
- How to replace the serpentine belts, along with tensioner removal, I will be replacing the alternators tension on a Volvo C30 T5. Similar procedure can also be found on the S40, V50, and C70 models. A slipping belt will squeal or chirp, this sound may come and ago and can be more noticeable during a morning dew or in the rain. Depending on the severity, this can disappear once the vehicle warms up. Sometimes you can apply a dressing to a squeaking or squealing belt, but for the most part that’s just a temporary fix and the noise will eventually come back. #volvo #volvoc30 #volvot5

Tools/Supplies Needed:
-jack
-jack stand
-T25 driver
-T30 driver
-10mm socket
-13mm socket
-side cutters
-3/8” drive ratchet
-3/8” drive 3” extension
-3/8” drive swivel joint
-safety glasses
Procedure:
-remove the wheel and place a jack stand under the subframe
-remove the 3 T25 torx screws on the rear of the fender liner.
-then 5 more T25 torx screws at the front of the fender liner
-remove the two 10mm plastic nuts on the inside of the fender liner
-remove the one T30 torx screw for the belly pan
-remove the fender liner
-using a T50 torx driver and a 3/8” ratchet, rotate the first tensioner clockwise to remove the tension and then remove the belt
-to remove a belt when you can’t relieve the tensioner, you’ll have the cut off the old belt as there isn’t any alternative methods
-to cut the belt, just use side cutters, it’s not hard but be careful so nothing flies back at you
-to replace the alternator tensioner, first you’ll need to remove the ac tensioner which is held on with a 13mm bolt
-pull the tensioner straight out
-now remove the alternator tensioner
-compare to old and new tensioners to ensure they are the same
-install the new tensioner, there is an alignment pin so you’ll know the tensioner is properly seated
-I cleaned up the threads of the bolts with a wire brush and applied a little medium grade thread locker
-to install the new belt, I’ve found it’s easiest to go from the top and push the belt down and then ensure it’s seated on the alternator
-pull it over on the ac compressor’s pulley
-then pull the tension back on the tensioner and slide the belt over the tensioner’s pulley
-reinstall the ac tensioner
compare the old and new belts by holding them between your fingers to verify they’re the same size
-again using the same process, remove the tension off the tensioner and install the belt
-install the fender liner
-install the screws in by hand, just to make sure everything is seated correctly
-on the door side of the fender, the liner has a tab which clips behind the fender’s trim
-finish install the screws, then tighten everything down
-reinstall the wheel and you’re done

Thank you for an informative video! I love the fact that there was no extra information, just the precise instructions and tips on how to do a good job!
Thank you so much for the feedback, always happy to help :)
Not referring to a stripped bolt, rather the method provided to swing the tensioner out of the way- it is a Torx ~50? but material is too soft. and cast, so not precise.The actual tensioner casting deforms easily, which will allow it to snap back while you are holding it out of the way, against spring tension, When this happens, it can easily break the stop for the spring, rendering the tensioner useless.
This video is very detail, clean verbal guidence. I have a 2005 v50 T5, that I picked up for $1000. Some reason I lost the a/c & alternator ... I realizd the belt is MIA, and I was confused if this was a multi serpentine belt system. This video really really helps alot.
I wish every how-to was just like this!
Thank you so much!
Excellent.. I've been a Volvo fan for a while.. mostly 850 and V70s till 2004. I'd never seen a diy c30 video. Quite informative and detailed
Thank you! I used to have an 850 actually, I did produce some videos on that car. I will be producing more C30 diy videos in the future too :)
Thanks massively for this video, I own a Ford Focus ST225 over here in the UK and they have the Volvo T5 engine and my tensioners are on the way out so I've bought the parts but everyone was saying this would be a pain in the arse of a job but it looks straight forward and thanks to your video I know exactly how to do it now. Thanks again!
Happy I could help and thank you for the feedback :) I have plenty more tutorials on this car as well, even have an in-depth video for the axle replacement. I was looking into an ST axle, but by the time shipping was factored in from Europe, it wasn't any cheaper sadly.
Thank you sooooo much!! I didn't have money to pay for a tow truck and pay for it to be diagnosed.. Will you help me so much You don't even understand. ❤
showed me how to put my new belt on correctly. fire !
Happy I was able to help!
Another great video. I've watched quite a few of your videos and love how helpful they are. Thanks for the great videos and keep it up!
Thank you, I really appreciate the kind words. This Friday I'll be releasing an axle replacement for this car as well.
Thank you for this video! I'm replacing my tensioners today myself. I'll save good amount of money, and I see it only takes 10-15 minutes of work. Great video, man!
No problem, happy to help. I have other tutorials on this car and will be having more in the future.
Add the tensioner steps with moving the tension to place belt a friend got confused but I love this good job
Man I can’t wait to do all this work to my c30 this weekend. I love that car! 🚗
Happy to help :) I have plenty more C30 videos too!
Man, you're really giving RoberyDIY a run for his money!! :)
Excellent informative no nonsense video. Thank you
You're welcome and thank you for the feedback!
Great video, thanks.
You are welcome!
This video was very helpful and informative. Thank you. Brian Merk
Thank you Brian, I really appreciate the feedback :)
What's the Torque Value on Tensioner 🔩 Screws *(?)
Not so easy if the (inner, alternator) tensioner has failed, which is very common, because the alternator tensioner is a poorly, nearly designed part. A t-50 torx socket, in aluminum alloy casting to hold a 40 pound spring, shows lack of conscious thought in the design. Because of this, it is quite common to have the torx bit deflect under tension, and slip out of the hole, at which point the tensioner snaps back, breaking the internal stop, which also retains the spring. When this happens (not if) you will have to remove at least the bottom 2 alternator bolts and loosen the top alternator bolt, and swing the alternator forward to extract the tensioner. and locate another tensioner. Warranty the other one based on a fatal design flaw. There is a way to save this design, though. Simply drill and tap a 10x1.5 LH thread hole where the torx socket hole is, and thread a short 10x1.5 LH thread bolt into it and tighten, using high strength (red) threadlocker. Once the threadlocker has hardened, you can use a regular socket (of whatever head size bolt you installed) to rotate the tensioner out of the way, and install or remove the belt. Just a note, we refer to bolt sizes by their thread diameter, and specify head diameter separately. (i.e. "10mm bolt with a 13mm head")
Trying to do this now. If I don’t have stripped bolt, does that mean I don’t have to remove the outer tensioner?
I still have lower tensioner rattle on a cold start despite CHANGING EVERYTHING - ask what I havent changed! I'm starting to think that my A/C compressor pulley is misaligned, but it made the noise before I changed it and therefore after...
I just had this same exact problem on my Volvo changing the belt, the tension pulley was stripped. It was a headache to say the least.
Thank you
i've unfortunately encountered I have the double pin tensioner; a real pain to get back in place even with my experience.
i've had it out of place to replace my alternator. now it's finally back in it's spot.
for everybody that needs to replace the double pinned tensioner, i'd recommend to unscrew the lower 2 bolts of the alternator, and loosen the top one. also unscrew the airhose to the airmass meter. hang up the alternator with a cabletie or something to make room for the tensioner to get back in place.
I'm so happy you have the exact same car as me. To good to be true.
No problem, happy to help!
Looks like this is on my list of things to do as I have chirping which is likely a slightly slip on one of the belts. I plan to replace both belts and tensioners as the vehicle is 15 years old. Are the two tensioners that you removed the same part number as I can only find one list on the suppliers website?
Thank you for making this video! I loved it. It was very helpful for my 2006 Volvo s40. I keep hearing a chirping sound and was thinking it was the tensioner but now I’m wondering if it’s a pulley gone bad.
Thank you sooo much
Top notch video 👌
Thank you so much!
Hi! Great DIY video. Wondering if the two belts are the same or they have different part numbers?
Great video easy to follow
No problem, happy to help :)
Thanks so much Mimo
What's the part number for the belts ? Are they the same length ?
What size is the bolt that holds in the tensioner pulley ?
Great, may be before resintall everything is to test it ;) thx for the video
Thank you!
Perfect explanation!!!
Thank you :)
42nm torque on those 2 bolts holding the tensioners
Excellent video. About to tackle my daughter's '07 C70 before she heads off to college. I'll be replacing the timing belt and this accessory belt vid will save me a lot of time. Do you have one for the T-Belt?
Thank you! Unfortunately I do not, but I do have a bunch of other repair videos for this car such as cabin filter replacement, engine air filter replacement, axle replacement, brake fluid flush and CEM cleaning.
4DIYers Great. I've changed the T belt in my Volvo 855t twice so I'm familiar with the process. Just haven't dealt with the vvt pulleys on the camshafts in the C70. Local shop gets $1,000 for the job. $300 in parts and I'll pocket the rest.
As far as I know there isn't any specific procedure. To be safe, I would line up the timing marks before removing the belt and as an added safety, make your own marks with a paint marker. You might also be able to find a procedure on another Volvo, the C30, C70, V50, and S40 is all part of the P1 platform so repair procedures are the same or similar.
Great work
great video and so imformative thx
Thank you :)
A great video
Thank you!
hello good explanation! know you don't have the c30 anymore. but have a question if that white sticker is no longer present, how do you know which tensioner and belt you need
Thank you! If the sticker is gone, you should be able to call the dealer, give them your vin, have them look up the part and ask them for the part number. They should be able to look up the engine code too.
@@4DIYers thanks 👍
If the belt is slipping and looks glazed, should I inspect if a pulley is locked up or is it just happening with age?
How to tell the squeeky is coming from the tensioner and not from a bad/wrong belt or a dynamo etc?
so one belt goes from alternator to a/c and one from crank to a/c right? what is the name of the crank-a/c belt? it snapped yesterday. do i have to change the tensioner if it was changed last year with the alternator?
Does this c30 require drive belts installed for car to start. Or, can car start without the belts on?
Yes you can start the car without a drive belt, although I would only run it for a couple minutes max.
Great video. Do I need to cut the belt if I only going to change the alternator? Do you also have a video of that?
does this apply to s60 and canti pull wheel or is it easier to remove all oh can you confirm T50 because other videos say T60?? And how do I know if I have right tension??
Good video.
Remove a fender on a v50. Anyone seen a video how to do it?
Easy job?
Thank you!
If your C30 is a manual will you please do a step by step on how to do a reverse clutch bleed?
Unfortunately I won't be doing any work on the clutch assembly anytime soon. However I did find this, so hopefully it helps www.pelicanparts.com/techarticles/Volvo-C30/129-TRANS-Clutch_Master_and_Slave_Cylinder_Replacement/129-TRANS-Clutch_Master_and_Slave_Cylinder_Replacement.htm
Great video!
Is it absolutely necessary to swap both tensioners even if they do not make any noise? For me, only the wedge is cracked.
Thank you! If I remember correctly, the recommended maintenance interval is during the timing belt replacement. But I would advise checking the bearing in the pulleys for any play or noise.
@@4DIYers Why are there two tensioners!!!
Merciiii
Is this the same for D5 engine? Cheers
I’m not sure, never had that model of engine in Canada.
in the Volvo theres a bracket with the pulley wheel do I need to change whole thing or just wheel pulley??
The bracket part would be the tensioner, so that has a spring assembly and they can fail over time too. It's usually best to change the whole thing. Not all companies allow for just the pulley to be replaced, it's cheap insurance to replace the whole thing and if you're paying a shop and the tensioner portion fails, you don't have to pay twice for basically the same job.
Hi do you have a video for the timing belt replacement? for a c30?
I don't have one for the timing belt as of yet.
What size belt
Hello mate this process is the same for Volvo v50 1.6 d Ecco as well ?
Thanks
That I'm not sure, we don't have the diesel model available in Canada.
The six thumbs downs must have been by mistake... Kudos man much appriciated!
Hi, what is the size of the belt
Would this be same for d3. Diesel 5 cylinder. Looks the same side either way
Unfortunately I can't be much help as we didn't have the diesel version available in Canada. However most serpentine belt replacements are somewhat similar. Just be sure to take some photos along the way to reference back for reassembly.
@@4DIYers Thanks
Nope! Not sure what S40 you had in mind or from what year, but mine from 2002 has different than yours, so unless you correct it, hands down
This applies to the second generation, yours is a first generation.
Hmm - anyone know if there is a difference between the two belts or are they the same size?
Crank to ac belt is smaller. It is 5pk847 and alternator belt is 5pk890
@@amthevision8931 Thanks!
Will this procedure work for a 2004 Volvo C70?
I believe for the 04 model it's a different procedure. 07+ C70 is basically the same as the C30 shown in the video, it's part of the P1 platform.
Thank you
No problem!
