The best detailed video on TH-cam on how to change a Merc tensioner pulley, well done.
One of the best videos I've seen. Well lit, high speed when it needs to be and very concise. Well done!
Been watching this guy everytime I have a problem with my ML320V6 he always makes it easy for me to understand how big or small the job is and things that you need to do the job absolute gentleman 💯 ✌️🙏👌👍
I am glad to be of service to you. I think the only people happy to see me are the end users. Dealerships.... Not so much.
What a GODsend this video was today! It may have actually prevented a divorce! 🤣 You see the older my husband gets, the less patience he has to work on our Mercedes ML500 (mine) & Mercedes E320 (his). So he pulled 2 bolts out of the tensioner thingy but 1 of the bolts was 3 times longer than the other bolt. When the tensioner didn't come off, he proceeded to stomp around the house using some VERY choice words!🤭 Even tho I'm a girl who would rather do her hair, a pedicure or her make up, I attempted to help him by googling the tensioner thingy. Then, a miracle happened & we found/watched your video! We determined that he neglected to push the pin back so he could get the correct screw out. As he looked at me with disgust while shooting testosterone everywhere, I heard him barely mutter "thanks honey". Long story short, the assembly tensioner thingy is replaced & my car runs like a top! So THANK YOU, THANK YOU, THANK YOU for taking the time to do these easy to follow videos where even a girl can do it! Well, if she wanted to! I wish you MAJOR Blessings & Prosperity! Know that your kindness has TRULY made a difference in the life of this Southern girl! Subscribed! 💞
I am glad that the video helped and that you and your husband was able to work on it together and get the vehicle running again.
Very Very stupid. Pin 5 mm pin . Just use 5 mm drill bit to put pin first. Mercedes Benz is Oldest mobile company. Design is very easy for mechanics. Pin hole just see New tensioner where is and just use finger to feel and put only. It's can not see. Don't try to see . But can feel by finger, After pulling down 17 mm socket handles. You guide the Block Aluminium to damage threads inside. You very very stupid man to teach blocks to condemned . Engine to condemn

I really love when video content like this is concise and straight to the point. Thank you very much for this! Videos like this are a "must watch" before I go to my local workshop :)
Glad it helped!
You've helped me address several issues on my GL320. I alway appreciate your videos. Straight to the point.
Glad the videos help
Great video, I always remove bottom bolt first(the top bolt will hold keep in place while holding the tension), and no need to remove pulley. I find it easier to do from underneath the car.
I watched a dozen of those videos. This is one of the best and simplest video on how to change a Mercedes Belt tension pulley. Thanks for this video.

Very helpful much appreciated, thank you!
Thanks and happy new year man!!!
Nice n easy.God bless man.
Great video man.
Spectacular ☆
Thank you 🙏
Awesome thank you 🤝👍
good! any tricks to put AC compressor back in place onE320 W211?thanks
Thank you for your videos. From one of your previous videos I will be doing the rear differential fluid myself sometime soon. I have a 2010 ML 350 base model. The four way power adjustable steering wheel will no longer go up or down but it will still go in and out. I believe a plastic piece inside the column is broken because I can feel the motor engage and then it acts like it is stuck. I talked with the dealer and they wanted $2k not including labor to replace the whole steering wheel assembly. Is there a simple fix for this or am I stuck living with this until I pay to replace it? Thank you.
You're Alright My Man, Thanks!
What size socket do you use to take off lower pulley its made diff from upper.
thanks great site i thank you and my pocket book thanks you and most of allmy benz thanks you
Is the idle tensioner suppose to move when the car is running or be still and spin cause mines move im not sure its suppose to?
Do you know if this is the same as a 2011 ML550? TIA
can you tell me which pulley is on the top left? that one just blew out on me
How did you diagnose this? Was it audible under acceleration?
Th pin doesn’t come out when I pull it is there another way to take it out.. or is there a tool I need to use.
Thank you for your videos, they being pretty helpful, can you include the prices on parts so we get an idea, big thank you from Tampa Bay Florida ✌️ USA.
I'll start including prices if possible. I do find that prices vary from dealership to dealership even in the same state.
Yes
How did you remove the pin out of the tensioner
Hello, i have a MBenz - ML350 - year 2009 -w164, i have a problem, when i open de driver door, the interior lights doesn´t turn on and the others functions doesn´t activate (mode parking, turn off of the radio and other accesories). Do you know, where is the switch to activate this function? Thanks and continue whith this videos. XOXO from Argentina.
the strings of the pulley screw are right or left
Thanks for the video... where did you get the part ?.... how much ?... thanks
Is that the same on the 08 c300?
How did you remove the actual pulley?
perfect video, I just wanted to see when and how he removed the pin he suggested be removed after installment
To remove that pin. Put some tension on that tensioner with that 17mm bolt and you can easily pull out that pin.
Hello, I need to replace my serpentine belt and I was wondering if you know if the process is the same on a 08 GL550 X164?
Yes 99% the same. Check your vin and get the exact belt needed.
Easy peasy 👍🏼🔩🔧
Great video and my question to you is what did you take out on the top to get to pulley and did you ever change crankshaft pulley?
exactly
Can you help me out? I see on this video that there is enough space where you working. Did you remove the radiator fan?
My radiator fan on my s550 W221 sames like its in the way. I see this is a W164, but the concept is same.
The w164 has alot of room. I didn't remove the radiator fan. You might have to remove yours if it's in the way
Brother…what is the size of the bolt? I cannot seem to find them online
Sir thank you for great video, last weekend i have changed rhe AC compressor and condenser ,but there strange noise from oullu when you press the throttle (rpm) also when turn off the AC the noise still exist. I installed used compressor not new one ,would you please guide me, the mechanic told me it from power pully . Really l spend alot off time and mony and still the same issue.
I have Mercedes c350
That's great but.... there is a Stabilus damper shock attached to the tensioner.... any feedback would be GREAT?
Hi Ray, what's happening with your tensioner?
@@iRepairAutos yep... replaced the tensioner, belt, and the two pullys.
Reused the damper ...there is just not a lot out there that shows what to do. The shock or dampener Co. is in Germany and the US dist. is worthless if you need help😰
On my 2002 ML500 the pulley itself on the tensioner is destroyed. I have a replacement pulley on the way but I have no idea how to remove the pulley FROM the tensioner.
Any ideas?
Thank you in advance.
Did you figure it out yet? I have the same problem
What is the number of d belt?
How can I take of tensioner if the relief bolt broke?
exactly same issue
How did u remove the bolt after installing
It's more of a pin. I screwed it out with a vice grip
Is there a way I can just remove the pulley it’s self?
the pulleys alone are available.....need a holy torx bit. not sure if LH or RH thread.
Where is this beautiful accent from .
My serpentine belt will not stay on the tensioner pulley after 10 seconds the belt slips completely off that pulley don’t know why. can I just replace the pulley on the tensioner or the whole thing? Thanks
save your time and consider replacing the complete tensioner unit.
Its not only the pulleys's bearing that wears out... after a while the spring tension digs itself in and the belt proper tension is severely degraded to the point it slips and gets hot, brakes etc... TENSIONERS are only good for 60kMi
👍
@Ash Moe "serpentine assembly" may be aka belt tensioner assembly. Just a guess. Replacing my belt, both idlers & tensioner today. Too fragile a system to not do it all in one go imo....& affordable. Not affordable if a shredded belt's ripple effects wreak havoc on other belt driven components
@@RothBeyondTheGrave the real Nugget here us a German design secret...
When the old belt tensioner is pegged in and the belt is slipping more grabing (100kMi)...
then the engine ECM sees the crankshaft not rotating smoothly (this is how misfires are detected!) because of the belt acting up,
ECM slowly detunrs the engine timing and throttle back the mixture.
The outcome is a shaky engine that feels worn out... courtesy of the cheap belt system (#1: tensioner, #2:wobly plastic idlers, #3: super long belt).
For less than $100 in parts + an ECM relearn you car runs strong again without belt chirps
👍
@Ash Moe it's easy to see if the serpentine tensioner is new or original: pop the hood and look all around the belt: how many clean parts do you see besides the 2 round pulleys?
👍
@@glasser2819 you've made me alot happier I just replaced that belt system! As soon as I heard that classic squeal & saw the smallest amount belt fray/grease on idlers, I wasn't about to wait
Hi 👍
So this causes a the engine to shake
My 08 c300 has a strut attached to it😮
What if the adjustment 🔩 bolt broke, how can I move it? If 🔩 bolt broke off?
Use an easy out , a small kit at the tool store

Hello, I have a 2012 GL450 that I'm trying to locate the fuel pressure sensor to change it out, I have look under both sides of the 2nd row seats & it's not located there, I have also looked under the right rear passenger side fender & it's not there, I'm totally loss at finding this sensr location, could you please assit me. Thanks Joe E
better to look on the common rail if there is one... in a "return-less" system pressure is very likely set directly in-tank by primary pump.
However modern engines use a secondary high-pressure pump for direct injection.
Note that these fuel systems are normally trouble free.
I don't get the part about the little pin, can you explain that better next time?
You need to pull the pin out after you install. That closes up the tension.
the pin is used to allow access to the second screw on the tensioner. Remove pin after routing belt and tightening the bolts
I would worry more about your oil leak!!!!🤣🤣🤣
Let not your heart be troubled. Lol
@@iRepairAutos you are right! These engines are built to leak oil - My M276 has been hoosing smelly engine oil since day one... also the plastic belt idlers have been wobbly and increasingly noisy since the second year 😅
Nice video! I have same oil leak around tensioner down to A/C compressor on C300 ( same m276 engine). Did anybody figure it out ? Could it be camshaft adjuster magnet ? Dealer has resealed passenger side before selling this car to me. But I guess it's time to do same on driver side. Car runs smooth though.
Thats not that bad in all honesty. My rule of thumb is if its not dripping i consider it a seep rather than a leak. Everything is going to seep a little oil over time its just the nature of cars. Not saying you can't keep your engine spotless but its going to drive you insane.
Mdavis pfrms bmw works big turbo that's for video just help out very will laA
Just re grease the sealed bearing to stop noise
Jeez that Mercedes has seen better days. It's a greesy mess
Lol. True
Never removed the pin
2:20 to 2.25...
Hi, Please watch my 2012 ML350. Do you think the noise is because of idler pulley? This comes only during cold starts (only first start in the morning and not later starts). Moreover it does not come in the summer or warm weather. I just replaced the PCV valve and intake gaskets due to P2279 error. This noise was there even before replacement but till date has never been an issue. I also changed serpentine belt an year back. Please tell me what you think after watching the video - th-cam.com/video/i22xJQbI8sM/w-d-xo.html
You look like DC's Teflon Don Sean Branch smh
Oh oh.....
@@iRepairAutos You're VERY handsome! Don't listen to jealous people! Just keep doing what you're doing cause you are appreciated GREATLY! 👍🏼
