On a 2.0 NA it can also be an alternator that can cause shaking. In my case my car had 200k. The belt was shaking rather violently. Replaced the alternator and it got better but still persisted. Changed the tensioner and now it's great.
Nice video! Also like that you use more pictures of the parts! A video of the (fairly typical) noise it makes would be even better! Keep it up! Greetings from Holland...
I had the timing belt replaced but on my A4 B5 but ignored the already deteriorating ribbed belt. After assembly I took it out for a test drive and lo and behold the ribbed belt snapped, got wond up by the crank pully taking a few electrical cables with it and mangling them completely. It had also affected the timing belt as well. Now I took it apart again and am starting all over. Point is never do a half-assed job.
Wow Humble, You were pretty young 9 years ago! I guess RU-vid ages you... Well, just had this happen on my wife's 2009 EOS (best car ever). Thankfully we have a good mechanic who reads the service bulletins and realized that the tensioner usually goes because something else causes it. In this case it was the clutch on the alternator (Yeah, VW has a complex alternator $$$). Thankfully everything is good now. Now we just have to deal with the DSG mechatronic 'thunk' in 1st gear when the transmission gets really hot. (That one's still not bad enough for a full rebuild) Thanks for the VW videos!
Often the alternator pulley will seize causing the tensioner to fail from the extra load. If tensioner fails also check alternator pulley at same time.
I have an 2016 a6 3.0t . My belt and tensioner literally broke while I was driving. I didn’t hear the noise until my engine mounts went bad and caused excessive vibration throughout my entire car. Excessive vibration from the busted engine mounts can also cause this.
Replaced alternator on Rabbit 2.5. Installed new belts (x2) and replaced two pulleys which had nicks and digs. Tensioners themselves felt fine so I reinstalled them. Car has never run better!
VW T28 Transporter 2.0 I've got a Battery light on my dash & Power steering has failed. So it could be this, cheers for the info. I'm guessing your Electric Shaver has also failed !
Hi! Thanks for the video! I have a 2013 VW Jetta 2.5L. In January (3 months ago) the drive belt broke which also broke the a/c belt. They replaced 2 pulleys but now it's making a sound as though the tensioner is broken. I can get back to you with more exact info about what they replaced, but is it possible this issue is caused by their negligence? How can I know? Thank you!
How often should a serpentine belt and tensioner be replaced on a 2.0 ? I have a 2018 Tiguan with 70,000 miles and figure I should change the belt, but can't find VW's recommended mileage for it.
OK, replacing a B6 CCTA belt tensioner is not the easiest job. It's secured by one "hard to access" screw behind the tensioner, but removing the alternator (or shifting it a little) gives you access to the screw. Now when you try to pull the tensioner out, it's blocked by the frame. I don't see any way to pull it out without lowering the engine a bit. 😢
Need help on T5.Has ripped off belt tensioner 4 times.Has new alt.has new A/C comp.Has new tensioner. Has new belt. Has had crank and power steer pullies cleaned.Still throws belt.Has done it a idle,has done it on start up. has done it at 60 kph.
Roughly at what mileage should I replace my serpentine belt, belt Tensioner on a 2016 VW Passat 1.8 TSI? I can’t find anything related to replacement in my owners manual.
Recently purchased a Serpentine belt kit from FCP Euro... They must've sent a used belt tensioner because the tensioner was not sent in its locked posistion. I ended up needed to call a friend to be able to use his vice grip, put an Allen key myself, then re-install the tensioner.
@@HumbleMechanic Ended up finding out.. that the AC pump ended up locking and causing a chain reaction, eating the tensioner and losing the belt... Luckily i didn't break the new belt just simply unplugged the compressor and ill deal with it in spring. It was weird diagnosing simply because it looked like a tensioner fail. but further diagnosing lead to the AC MK4 1.8t
My 06 Camry makes that rattle sound only when something is turned on like the AC compressor or the radiator fans kicks in. But it's much worse with the AC compressor on. Def suspect to be the belt tensioner.
My 2015 crafter is over tightening the belt and pushing it into the idler pully causing the belt to rub together and eventually break. Any suggestions?
I bought a used stock 2011 VW CC 2.0t with over 110k miles on it & already replaced a lot of important components and drives fine. Should i consider replacing the tensioner or pulleys ? I already replaced the belt
Don’t mind dropping some money for a hood pulley and serpentine belt, any suggestions as to what makes one better than the other? What should I be looking for? Thanks man your videos are so helpful!
This would help me too, suppose to be getting a 2014 1.4L with 71k miles approx. Still in good shape and low milage, but would like to get the parts set down in advance. Also, what pistons can be used on this said engine.
I had my timing belt replaced along with my serpentine belt, 5 days later, the tensioner came off. I'm trying to understand if it was possible to oversee the problem as a mechanic... or if it was a bad installation...
I would love to see a video on fuel related issue. Currently have the craziest problem i cant find AHH! car stalling on warm starts and after pumping gas rpms are dropping then stalling. Any ideas? low pressure fuel pump failure maybe? ? So troubling. If i give it throttle to save it from stalling it will idle fine. So many misfires. coils/plugs and pcv all fine. Awesome videos thanks! 2011 gti
I installed a new oem serp tensioner on a 1.8t and the belt is not aligned with the pulley. I even remembered to put the black bracket between the bolt and tensioner. I can't figure out how to align it. I'm going nuts. Help! 🤯
mine literally detonated (retaining ring holding it together) while i was trying to change my alternator yesterday. looked to be the original factory part. change those with your belts, yo.
The 2.0 Touareg is a pain but I changed just the pulley and also found the alternator pulley was bad…update.. alternator replaced( lifetime warranty) squeak remains and on two locations serpentine side and the driver side…..thinking this is going to die soon…also the tensioner on a Touareg has a shaft running through to the other side so you pretty much have to drop the motor to replace….not so much diy
Can you elaborate on the spray lubricant? What kind, where to aim it, use proactively with regular belt change, or only if noisy? I'd have guessed the forces on those bearings would need high-temp, thick grease & I'd worry a spray might degrade original grease? Is that not a problem because spray won't get to sealed bearings - just trying to hit spots where spring is creaking against housing...?
Last Saturday I had to drive some 40km home on battery only, since the tensioner on my 1995 Golf III failed and the engine wasn't turning the generator anymore. I guess, this means the battery is quite good, we are obliged to use headligths at all times, besides it times I needed to turn the wipers on (they moved really sloooooow), and after all that battery was at 11,4V. P.S. Before that I had a weird problem with idle revs _dropping_ when AC is turned off, which seemed to be weird, it should drop when another device is turned on, not off, I think, so it's sort of counter intuitive. Besides, there was some noise, not exactly squeaking, but a noise, when taking foot of the accelerator, which might be connected to the issue... or not. Got to see what changes after fixing it.
Hi there, I've got a 1.9 Tdi 9n3 polo and I'm not sure how the tensioner comes off. It looks like it's bolted on with the alternator but I'm not sure. I've got a noise but I did check the pulley on the tensioner and it didn't make any noise and it was smooth when I rolled it. So my last guess is its the alternator pulley. ?? Let me know what you think.
So my 2001 vw eurovan serpentine started chirping/ squealing after the shop put a new clutch in the a/c. Returned later and they said it’s the tensioner but NOBODY anywhere has the tensioner for that vehicle. Assuming it is the tensioner, what options are available besides waiting for catastrophic failure?
I know this is a old video but I have 2006 vw jetta 1.9 tdi brm motor and my Tensioner, go and shred my belt I got a new tensioner and belt put on reprime the system but I got crank but no start
Hi, I own a 94 golf GT Special. It's a 1.8 8v with 295.000kms. I've had to replace a lot of parts since I daily drive it 10.000kms a year, but the engine seems to be running along nicely. Only replaced valve tappets. Now I recognise a lot of what you mentioned but someone warned me that there's play on my crankshaft. I've found a few metal splinters on my oil pin and since the crankshaft drives the belt, I'm concerned it's not my belt tensioner but my crankshaft crapping out? When I take the cover off of the belt, I notice that the belt is sitting over the edge of the camshaft pulley by like 1/3rd of the width of the belt. Also the belt has been replaced twice in 30000kms and seems to wear out super quick. It squeals an awful lot and turning on heating etc makes it worse before it disappears. When idling it sounds a bit rough like there's some wear and tear somewhere along the belt and pulleys. When I pull the belt back and forth I hear a metal clacking noise, similar to a torque wrench locking. That's all I know so far. I'm shy to start diy'ing myself since I lack the tools nor the space and it's my daily so I'd rather pinpoint the problem/s and let a good independent mechanic fix it. Also if it means my engine is dead and a swap is the best option, that's gonna top €7000+ already spent maintaining a €950 car that has more issues. I mean i love the thing but it's getting tough.
My belt on amarok 2.0 this is stretched in every two months such that tensioner pully touches the below pully, I have already changed four belts to now. Help what's that issue
So my tentioner moves alot and I can hear a clunking noise after it warms up and it does go faster with rpm. It doesn't move or clunk when cold and in park only after driving and or warmed up. I guess I'm unsure if this is a tentioner issue or alternator issue. I do get 14 volts constant
urgh, you made me remember i had to change the alternator ratchet-hub(can't remember the proper name for the directional hub they have) on my car(it was getting really noisy), expensive bugger!
I need your help please... Just replaced the belt tensioner on my aunt's 2012 vw jetta TDI after it had catastrophic failure, installed a exact replacement and the tensioner still makes a chirping noise at low rpm and bounces/shakes from side to side... I double checked installation, everything looks normal, also looked at the alternator pully before I put the OLD belt back on and it has zero movement/noise in any direction and seems to be tracking correctly. The old belt looks good, could it be still causing this issue? Your help would be most appreciated, thanks ahead of time.
Long time watcher maybe can help me 2012 vw eos 2.0 tsi turbo. The low oil pressure light flashed and then car turned it self off and white smoke out exhaust. Mechanic said new motor. Maybe you can help didn't overheat and has codes p025c and p0301 thanks love the shows
I have a 2010 Jetta 2.5l that needs a new tensioning Roller for a ribbed belt for the AC Compressor. Do I have to replace the whole assembly or can I just replace the roller
Hey Charles, we have a 2.5 2006 Jetta with the electromechanical steering. Today the power steering warning light came on and it was orange. Is there any chance that a bad serpentine belt tensioner could cause this? Thanks for your videos! They have helped us out a lot!
Are they serviceable? I bought a billet pulley which shows to repack the grease on it but does that make my tensioner like new again or should I buy a new tensioner with the billet pulley ? Thanks
Hi I have 2012 tiguan tsi 118kw and the idler tensioner has threaded it's bolt when I was trying to renew serpentine belt. Any advise on how to remove and replace and what tools I need?
I have a 2007 golf gti and there’s a clicking sound coming from the cambelt/alternator area is this a problem? And if so do you know what’s wrong and how to fix it?
I have a 2.0l tdi common rail engine code CRLB I am starting to have some weird noises from the car and strange idle can I send u a video clip somewhere bc I don't want to get ripped off by a dealer
IMO Vw cars are as good as any newer car. In some ways better and some maybe not as good. The bug because it is hard to get access to tends not to get serviced as well as others. so It has more problems. The key is following maintenance and making sure that is done right and thorough. I like DSG and it has less long term issues than other automatics. But other people have the infamous valve body fail and say they are POS. but an in car repair vs total rebuild I would take a dsg over any other automatic..
I have a question Bro... I recently replaced the bracket that holds power steering pump,a.c. compressor and alternator in my AWP 1.8t engine. The thread on the bolts that holds the serpentine belt tensioner were striped so that caused the tensioner to move and eventually the serpentine belt shereded in pieces. I replaced the bracket but after I put everything back together I notice that the tensioner puts so much pressure on the belt causing the belt to touch the belt that passers on the a.c. compressor loop is that formal.. do I have a bad tensioner?
Quick Question. I have 2005 Polo 1.9 with a ADY Engine. The Roller on Tensioner doesn't fail. nor my Serpentine Belt . BUt the Tensioner it self splits in 2. its the 3rd one in 6 Months. different Suppliers and Makes. what can cause this Problem. dont get any warning or Noise.

Do you know where I can get a service manual similar to a Chilton or Haynes? Having trouble finding info on my 2014 Q5 3.0 tdi for maintenance and repairs. Thanks
I have a mk4 r32. Would a faulty tensioner and or belt cause an alternator to not output the correct amount of voltage? I just replaced the alternator and when I turn the air conditioner on, the voltage drops from 13.9 to a little over 12 volts. I replaced the original alternator thinking it was going bad but still getting the same issue. Any ideas?

Hi Humblemechanic, Could you tell me tightening torque of the two torx screws for the v-belt tensioner? I have a MK7 Gti Petformance from july 2013. Thanks in advance Wheelman ;)
Speaking of noises, I'm changing the cam chain tensioner this weekend on my 01 Jetta 1.8T. When putting the new tensioner on, the videos I've seen, they put RTV going out from either side of the half moon seal under the tensioner. Is there anywhere else it needs to go? I saw one guy put it along the convex side of the half moon seal as well. Would love your expert advice to help avoid some unwanted leaks!
I have a mk3 VR6 and it squeaks bad when I start I thought it was my tensioner but it wasn’t it gets louder when i accelerate and drive off , I should check all the pulleys and see which one is causing that noise ..
I have a 2009 2.0TSI CC and the tensioner doesn't have a squared know on the the top for a 16 or 17 mm wrench do you know if there is a certain way to release this tensioner? There is a rounded knob on tope with a hole on the side for the locking key
Hi just a question that i have B7 2021 Passat and i hear pulley noise inside the car but not in bonnet. Can you confirm what pulley it could be and when i turn AC on the noise either hide or gone.
I changed my timing belt then my serpentine belt 5 minuets after starting engine my serpentine belt flew off and car cut off timing belt was fine but serpentine seemed all on track and properly tensioned any advice what might have caused that
I’m pulling the water pump on my Jetta so I’ll have the engine up. I’ll be replacing belts. Should I just check the pulleys and tensioners or any that should just be replaced while it’s out? I have an 06 2.5L 130k mi.
You my be able to help me out: I have a 2ltd engine turbo high mileage audi A4 2008 model. My steering vibrate heavily when I m not on the accelerator. I doesn't vibrate when I m accelerating ie during normal driving but does when eg parking and not on the gas pedal.
anyone know if I can swap the tensioner with a new one without adjusting anything, do they come pre-adjusted or can I take out the old one and simply put in a new one??
Hey so I have a mk4 vr6 12v gti i had a squeak on the belt so i replaced the belt and it went away, a few days later it came back, so then i changed the idler pulley and the water pump pulley and the water pump plus the belt again and the noise went away, but now it came back again and I don't know what it is, every time I drive over a puddle the squeak goes away what can it be?
I own a VW GOL wish is a Brazilian model (I don't know if you ever hear about it in America), when I m driving it I can hear knocking sound coming out of what is under the hood (not exactly the engine) however by riding more often I noticed that the noise was getting louder. One day by getting back from work, I decided to check the engine and the tensioner of the serpentine belt just split up so the belt got held loose. So I would like to know; can I keep running my car prior replacing the tensioner. Thank you.
I've kentworth T600 Truck . my truck's bottom tensioner pulley smoked and came off due to overheating . can i bypass this tensioner by using 2-3 shorter belt ? angle /line is good with main engine shift pulley and there is idle pulley at at corners . i need to bypass it if possible just to get home . u know over the road service told me to bring u part and install it will coast 600$ but if i get to home i can buy part and do it with only 200$ I'm broken ... any advise pls
What would cause an the belt to slip and move over towards the motor on 01 Jetta vr6. It takes part of the belt off all the way around then it runs fine for awhile but you can see on the used belt that it is slipping on the pulleys.
could be a number of things. Wrong belt will do that, a slipping or failing component on the circuit will do that. Also an improperly installed part will do that.
HumbleMechanic I have the right belt. Double checked with the parts store. while doing some research on this it I think it might be that the pulleys are not allied. We just did a motor swap (ourselves) and I was having this issue before. It says on there we might need a special tool. Is that the case? I want to try the repairs that don't involve buying more parts. www.cartechbooks.com/techtips/serpbelt/ Thank you for answering my questions. We've put a lot of time and money into my Jetta and I refuse to get rid of her.
Hi would u make a video on how to replace a belt tensioner on 08 Jetta 2.0t cuz this cars came with a factory tensioner that can't be eemoved just by removing belt and a bolt that holds it to the block,mine looks like i gotta remove alternator or ac compressor just to get to some bolt that are hidden behind it,please help thanks.
