This 2005 VW Jetta TDI came into the shop with a chirping noise from the belt and rattling noise from the engine. The belt had already been replaced and that helped the chirp but not the rattle. In this video I will show you how to test the alternator decoupler pulley sometime called an overrun clutch pulley and replace the pulley if it is bad. Replacement does require a couple of special tool which I will list below. Always remember to be safe while working under the hood and especially while near the belt system while the engine is running. Shut engine off and remove key from vehicle before starting the hands on testing and repair.
The VW special tool kit from AST - amzn.to/2MBXzAF
The decoupler socket from Hazet - amzn.to/2vDWIZT
Cheap version of the Hazet socket - amzn.to/2P2n0gC
Basic decoupler tool kit - amzn.to/2MEgYkP

Great video, tried to replace mine last year with no joy, watched your video and learned about the tensioner pin! Still struggled with getting the pulley to start loosening but once it started it was a piece of cake. No more vibrations, no more rattling, no more squeaky steering. Thanks for the vid 👍

See i was a bit concerned about the belt tentioner vibrating thinking the speing was failing. To find posts about the alternator pully failing as a common issue. I was under the impression i would need to get a new alternator. However seeing this video gives me a much better insight on if i need to fix or replace any pully parts. Your video was truely helpful! And i learned a few things from this video tonight. Definately bookmarking this for future reference.

What an interesting repair. You had me scratching my head regarding the clockwise method to spin the tensioner off. My first thought was that it is left handed, but not so! You're spinning the alternator shaft from 'behind', meaning that the pulley bearing is threaded onto the shaft with right hand threads.... Like turning the workpiece to thread on a bolt, you spin the opposite way!

I have this problem on my 06 Audi A3 1.9tdi, the belts makes so much noise, was really dissapointed when i got a new tensioner coz it didnt change anything and only this morning whilst reversing in the driveway, the alternator decoupler pulley seized and fell off. Upon investigating the tensioner, i realised i could replace the coupler pulley. After fitting another 2nd tensioner again this morning i realised the noise problem is still there and that got me searching on youtube and im glad i found this video

@ThePracticalMechanic
@ThePracticalMechanic 4 жыл бұрын
It can cause a whine or chirping noise if the alternator pulley is is trying to lock up and then releases. Sometimes the whining noise can be cause the alternator itself when it try’s to recharge the battery after startup. You may want to pickup a cheap stethoscope from harbor freight and see if you can tell where the whine is coming from. I would then pull the serpentine belt off and see if the noise goes away. This confirms that the problem is indeed in the belt drive system. Is you have a gasoline model the noise could be from secondary air injection pump as well. I had a passat in the shop a few days ago that had turbo whine for about 3minutes after startup as well.

I appreciate this video. The links provided show a few options for necessary tools. Would you recommend the specific tools you have over the others or would you say the others might have an advantage over the set featured in this video? Also, is the Hazet decoupler socket a high quality tool or just a good tool? Do you have an opinion on the triple squares you have compared to SnapOn's version? Finally, my MKIV GTI VR6 has 136K miles and the original pulleys. Am I pushing the limits of the pulley's life, and the life of the alternator at this point? Unsure how long each typically lasts on a MKIV GTI 2.8L VR6 or even a MKIV GTI 1.8L. Thanks in advance for your feedback.

It sounds like sheesh sheesshhh shessh sheeshhh then goes quiet then come back again after few minutes. Trying to describe it best I could lol. Happens with AC on or off. The noise appeared 2 weeks after replacing AC compressor clutch.

Why is the tensioner still vibrating so much at the end of the video? I have replaced all pulleys and put a new serpentine belt along with a new tensioner. However, the tensioner is vibrating just like in this video, and it makes a fairly loud hissing noise. The mechanic says it's normal but doesnt seem normal to me. I've seen a few videos of this engine where the tensioner barely moves, this is the first video in which the tensioner vibrates just like mine.

nigel mitchell it seems strange that VW routes the belt this way but it is the correct routing for this engine. The serpentine belt is double sided and has micro-v profiles on both surfaces. VW changed to a much longer belt and much more complicated belt routing a few yrs later and on those the compressor does rotate in a clockwise rotation.

@@ThePracticalMechanic My apologies PM, never heard of such a thing.! Thought it was only the French who were that accentric!.! I looked you up as I'm having bouncing tensioner problems with a Citroen C2 1.4 HDI. Changed the belt, tensioner and mass damper crank pulley, still it bounces.! So now only things left to change are alternator pulley, which is locked up, then AC pump, both of which spin quietly and smoothly. Extremely slight wobble to alternator pulley. Seems incredible to look at it that this could be causing the bounce, well you live and learn, as they say. I've had my head under bonnets for 45 years but....... Stay safe buddy. Mitch.

I have a 2000 jetta tdi where the alternator pulley broke off I'm not sure if I need the extra spline tool or does one of these kits or a couple of these kids have everything I need but just differ in price?

Some of the kit include more options than others. The basic kit should have everything needed for the VW amzn.to/2E5MbeS Let me know how it goes.

@@ThePracticalMechanic I found the pulley on idparts and it has a kit for 29.95. well whatever some of the description parts that it has which I believe is only 3 pieces and has a 17 mm head for the box wrench and I don't see any 17 mm in the description of the basic kit

@@coryboggs6247 if this is the one you were looking at it should do the trick. www.idparts.com/metalnerd-serrated-alternator-pulley-bit-set-a4a5-p-564.html I looked at the description of the basic kit and it doesn't show the head size but it is the 33 splined socket.

Yes that is the one I'm talking about I will be purchasing the basic kit them through Amazon and buying the alternator pulley off of idparts.I was just curious and worried why you had four different links I thought maybe I should also buy that splined socket

Cory Boggs No problem. Some people want the exact tool I’m using because they know it will fit and they normally have a slightly better fit, finish and warranty. I normally include both the tools I use and also a more cost effective option. I will make sure to clarify the description.

Arturas Karelis yup. I know it looks strange but this is a double sided micro V belt. It has grooves on both sides even though some of the pillows are smooth.
