Hello W204 c250 cdi 2011 worked spot on, and it didn't take very long. Chain noise on the first start up, then all good it's been a week now. Moving on to the next job. Thank you very much for saving me a lot of money
Thank you for the video!! Mine is year 2010, C200, W204 and OM651, and 200 000 km. I followed the steps and all went well except for one thing. The lower edge of the heat shield was in the way of getting the 27 mm in place onto the tensioner. I had to remove two of the bolts holding the heat shield, and then bending the shield maybe 10mm outwards, away from the tensioner. (The last bolt holding the shield was not reachable)😊 Also worth mentioning; the rattle at first startup was terrible and lasted for quite a few seconds!! I hope it didn't ruin anything in there. 😮😮😮 We hope for the best.
UPDATE AUG 2024 1. For c class w204 om651 near before taking out the tensioner, there is 1 more element(starter protection) with 2 bolts that needs to be lossened because your wrench cannot touch completly the tensioner 2.first engine start after tensioner swap has a big rattle sound for 2-4 seconds because the new tensioner doesnt have pressured oil inside, so he needs to build it inside the engine
Just did that, took around 2h guys with a help of a friend, some bolts are paint in a… to get to and put them back on, seems like it did the job for me
Czesc, mam problem z grzechotaniem po odpaleniu auta na zimnym silniku. Tylko przy starcie przez sekunde lub dwie slychac grzechot. Pozniej jest ok i nie ma zadnych bledow. Co najgorsze, stalo sie to po wymianie rozrzadu (kola zebate VAICO, lancuch ori, napinacz ori). Widze ze pisza tez o walkach rozrzadu ale nie chce mi sie wierzyc w ta teorie tym bardziej ze przed wymiana bylo ok. Podpowiesz cos?
Hi great video and good to see the positive comments. Quick question please. Is it necessary to prime the new tensioner? I suspect the oil pressure will build the tensioner pressure up when started but that first start will mean the tensioner won’t be primed without oil? I see user andrewkerrigan had the noise on first start up. I suspect this means the tensioner isn’t pre primed? Thanks
Hello everyone!I start by saying that,I did what Mr. showed us in the video,but without success,I changed the tensioner with the original Mercedes parts,and the noise still persists,so I don't know what is the problem,thank you
@@Mercedesadventurz hi can i ask are you experienced in this om651 chain rattle cold start issue. As yes tensioners fail. But i have a theory on the route cause. That sets this in motion. Could we chat here
@@dieschnellekatze do you also have this rattle on a morning cold start. Yes it can be tensioner. But ive got some other theorys on the route cause. That sets this in motion. Infact not just a theory. In my case ive proved by various experiments. My theory is fact. If your interested to hear. Reply here

Good to hear man! Whats the next job?!

Hi thanks for the video. After installing the new tensioner, can the engine be restarted immediately without problems?
Do you have to put the crank centre ? What if you do this without remove the fan belt and crank not centre ?
Any ideas why to do crank in centre?
Dose the GLE 2016 needs to follow exactly the same steps in order to change the tensioner?
Excellent video. Many thanks

I cannot see how you can avoid priming it too much???
Great job💪 Can you tell me please the om number of the new bolt? Tanks✌️
Great video, Clear and concise. Thank you.
Really helpful video. Thanks!
Whats the part number for this tensioner snd would it work on e250 petrol 2010. Do you have a link for the part?
Hello everyone!I start by saying that,I did what Mr. showed us in the video,but without success,I changed the tensioner with the original Mercedes parts,and the noise still persists,so I don't know what is the problem,thank you
What noise? I’m also looking for help with a noise.
Thanks. Did you have to prime the tensioner at all?
No priming.
Thanks for your video! How long it will take to change? 1 day?
No problem, the job shouldnt take more than an hour if you are handy.
@@Mercedesadventurz 😀🫡😎
@@Mercedesadventurz than dude! i change my in 2.5h and its good no noise!! wow!
Do you have a link for the new tensioner?
I can only find 2 hole ones, not the new 4 hole.
How much would costs a labour job for doing this ? If part provided.. thx
I the process the same on the om651 c class 220?
Same process same engine
Is it 2012 e350?
I am about to attempt mine. One question please. Do you have to drain any oil first? Thank you.
No need to, minimal amount of oil will come out of the tensioner. Spray area with brake cleaner after you have installed the new one and ur good
@@Mercedesadventurz Good news. Thanks again for the very detailed video.

I'm about to do mine now
هل يمكن لي ان ارسل لك فيديو بسبب مشكلة قريبه من ذالك !؟؟
Did the rattle come back eventually or stay away
I also would like to know

Maybe Vacuumpump can make some scary noises like the chain. I drive a w204 with the om651...what theorys do you have?
@@garethoswald3392did you figure out what was making noise?
In this case you don't need to rotate nothing, is not needed.
Says who
Yes you do, otherwise will be hard to put new one in
@@Mercedesadventurz I say, I did it without moving nothing.
Correct, TDC is irrelevant as regards the chain tensioner. Obviously different if you were replacing the chain.
So we dont need to change the timing chain?
I made the mistake of buying a mercedes this year. It needs everything. Suspension, balance shaft repair and so on. Ugg.
@@Husky_Pufferfish It is a very poorly made part in your engine.
