Just did this on my M135i, anyone debating it, do it, it's so easy just get the right tools. My old tensioner was definitely moving, new one is absolutely rock solid.
Mine blew up because the bearing of my tensioner broke. I think i try to do it myself.
@@TomMarvoloRiddle01 the idle pulley blew on mine.
Perfect timing !! I am over 98k miles and I need to replace a whole bunch of stuff including the belts and tensioner... Thanks for the reminder...
😂 my dude! That hair doo is crazy looong bro!. You stay keeping me on my toes with my vehicle, i drive a 335i e93 2011 convertible with the N55 engine and every time i watch one of your videos it helps me get an idea of what i am getting myself into, not just that but you save me HELLAAAA MONEY, thank you.
Thanks for the video. I just bought 2013 X3 35i M Sport yesterday and today, I noticed the tensioner wobbling. I just ordered the kit and this video will make it a simple ordeal. Many thanks!
Wow, I finally found a video that explains the diagram. I searched for hours and none on the F15 model. Thank you so much. The only great video on this topic. Blessings!
Great video! Here's a tip that will remove a lot of frustration when fitting a new belt.
Install the idler pulley after routing the belt!!! So much easier...
Holy **** you are a legend… I couldn’t for the life of me get the belt on my e70… I want to high five you
Excellent video! Really helped me out with the correct orientation of the tensioner, torque specs and the belt routing. Thank you!!
Please do a oil filter housing gasket diy
I want to do this and that at the same time
10 out of 10 for a instructional video. tool sizes and torque specs. appreciate you.
Awesome. I need to release tension on the crank hub to realign it while installing crank hub capture and this video was perfect.
perfect ! you make some of the best video guides on how to fix things, truly impressive production and camera man skills well done fellas !!! merry Christmas
Thank you for upload. Yesterday changed and replaced my belt, two pulleys and the tension pulley. N55gas 3.5 Xi x5. Current mileage 176,741 kms. When I took out the lower pulley that was making a sound, probably was the original factory. I bought the pulley and tensioner from FCP - OEM. Fit like glove. The top pulley was leaking some grease also. Ok
Good video. Hard to really show what's going on in such a tight space but you guys did a great job with lighting and trying your best not to get in the way of the camera. I do have a suggestion for what you could use to replace that retention pin instead of a drill bit. Drill bits are very brittle and might snap when being used in this method, especially if someone decided to use a smaller diameter bit than what you used. I would use a nail instead as they are ductile and would bend before breaking, a dime a dozen, and if you accidentally left it in before removing the tensioner, it wouldn't be the end of the world. I'm not familiar with how much force the spring inside the tension arm is applying so take this suggestion for what it is, a thought.
Great video, just did it to my m235i. If you have any mechanical knowledge then this is very easy to do, just make sure you have the right tools for the job.
My e92 n55 tensioner started making a rattle, quickly replaced before the failure! Great video
Could you here it? Was it loud?
weird! sorry to hear this. Mine has some play when the engine is running. is this normal? mine moves a bit less
Did this today using this DIY. Thanks Bryan!
Got the pieces on the mail yesterday ahah perfect timing
Excellent video, very concise and informative!
Shout out to Brian for the speedy delivery of my order. Oh, great service too.
Best instructions I’ve seen. Thank you so much
Thanks for the video, had a hard time for for my same model.
Thanks Brian . Will change mine
Nice work guys, as always
Nice video! This will come in handy one day!
Learn something new everyday! Thanks Kies fam 🤘
Speedy Gonz F22 why do we need to change this? What are the symptoms?
@@diegonavyhotmail it’s for prevention before it fails
Are you able to put the Intake link on here please? Love the channel!
Ha! It was minutes into the video before I noticed your "set lighting"! ....Talk about being focus! LOL!
That 'belt' is really W I D E! Note, I place my old belt(s) in the boot,...this way,...if ever I need one,...even if it's old,..I have a 'spare'! Or in the event I run into some DOTR,...dead on the road needs a belt! Ya never know...
Edit: I prolly would have just done "40 Newton Meters",...LOL!
are you ok?
Just complete this job … I completely ignored the drill bit step and relieved the tension with one hand and pulled the belt off of the idler pulley with the other lol no need to fumble and risk breaking a tool you might need down the line … kept the pin from the new tensioner in tool box just in case
On the F10 535i, there is a bracket that blocks the bolt head of the Idler pulley, this bracket holds in place the two AC compressor hoses.
Superb video editing, recording and so on
Thanks for excellent video. I need to do this on my N54T. Have tensioner & two deflection pulleys ready to go.
The torque specs confuse me. I've seen one sheet that days 40nm on all. Then another that says 60nm on deflection pulley & 25nm +90 degree turn on tensioner.
Why so varied?
Mine is moving exactly like this I just hope it doesn't take too long to arrive I was planning on driving some canyons this summer 😭
Great work!! Might have to have a peak at mine...
Great Tutorial 👍🏼
Great job,well done video.
What about us N20 users 😭 I have so many questions as someone that wants to continue working on my car! I have 6 years of part time experience as an electrical motor mechanic and I am now a full time electrical engineer. I’ve been following your channel for a year now! Thanks for all the awesome content, btw!
n20 is pretty similar if not slightly easier imo because the location has a little more room. Pretty much the exact same process as this one was, just in a different location. I used this guide for it.
ruclips.net/video/oN4acq0rd8U/видео.html
Joseph Frasier it’s exactly the same on N20, and yes much easier since the engine has more space :) just did this one mine
Hey Kies we need an oil housing filter gasket change, cannot find a proper vide on internet thanks, greatly appreciated.:))
Hope to see the video tutorial of replacting the alternator on your channel
If the tensioner had a slight wobble but no noise does it need to be replaced?
Going to be doing this soon but I don’t see why you’d need the drill bit … can you just remove the belt from the tensioner pulley immediately and then you won’t need to the pulley to be locked anymore?
2015, F10, N55. After replacing the ser. belt, the tensioner and the idler pulley, i have a feeling that the engine is more responsive, almost no lag! Does that make any sense?
Thanks
@kiesmotorsports
Hi Brian . I just got a 328xi 2010. I see you’re in Jersey, how much would it cost to install a backup cam, I saw you installed it in one of your older videos. Please let me know thanks
I ordered the tensioner and came today but no bolt. I plan on doing this tomorow, not a big deal if I use the same bolt that’s on the old tensioner right?
After how many years you recommend change the belt? Thanks!
Thanks, Is the F80 any different?
thanks, the perfect instrucion for newbies like me. :)
Job is done. Easy going 😅💪
yep time for me to get my hands dirty on the f10, thanks dude
What whould happen if I just cut the belt and then remove the tensioner? Seems easier for me because you know, it will be replaced anyway?
Should it be rock solid though? I've installed a new one with belt and it slightly wobbles still
Nice B roll, I gotta start doing that on my videos, hecka cool lol :)
How do you know you need to replace the pulley and idler as well as at 140k miles the belt and chain tensioner was all that was changed by BMW on my 2012 F30 320d sport.
Nice job!
At 60k miles I had my belt rip off, and dig through the crankshaft seal (front main seal). Pieces of belt ended up inside of the engine. Thankfully I turned the car off on time and we were able to pull the bottom end off and clean out all the belt pieces.
50k mike is a must for belt and tensioner replacement on these cars.
Just today i had done a quick first gear pull and after when I was coming to a stop I heard a noise as if I was dragging something from my bumper I was at my gate for my community when the belt ripped off got home and shut the car, my friend mentioned this same worry, is it easy for it to slip into the crankshaft pull ?
did you have an OFHG leak?
@@MustafaDarwiche bro same dude u ever fix?
wow! sorry to hear that! Mine moves a bit, I hope this doesn't happen to me.
Hi hopefully you see this comment, the belt you what size was it? I have a contitech 1390 belt but it seems a bit small I can’t get it looped around was yours difficult to install?
Thank you!
I just got them changed yesterday.
You shouldn't need the drillbit. That's why they don't provide a metal rod for your old tensioner.
It's meant for you to remove the belt while holding the tensioner with the T60. Once you have the belt off, you can release the T60. They have the new one set for your convenience only.
I like your idea because the engine bay is tight. But just saying you don't need the drillbit. You can save the metal rod from the new tensioner for the next job.
Agreed, and if you do it this way you can take a lot more tension off the belt… it comes off much easier.
Finally something f10!!!! Yay
That wasn’t an F10. Lose.
I just bought an M2 with the n55 , i noticed a wobble in the crankpulley and the tensioner is vibrating too, the car only has 16.000km ,I cant believe the tensioner is already gone bad.. should i be worried ?
Mines making a whining noise. Could this be the bearings in the idler pulley?
My idler pully bearing seized and sheerd in half leaving me stranded last summer, coulda used this back then 👍
wow!!! sorry to hear that!!! was it moving first like this one? mine moves a bit when running. is this normal?
I have an f10 n55 do you sell the kit tensionner or its only for the f30 ?
Just replaced this and still have lots of movement in the tensioner- almost looks like it’s coming from the balancer. Any ideas?
Water pump replacement for f30 please since its a common issue with n55
Is this the same procedure for the s55?
Thanks a lot
Necessary for N20/N26? I have n26
Why there is so much corrosioned marks on the engine? Mine got the same problem.
Do you have a set for a b58?
Wait 60Nm for deflective pulley and 38ftlbs for tensioner?
Fantastic videos thanks guys. 2 questions hopefully someone can help.
1. I suspect this is the repair that I need to do, but I'm not 100% sure. My car currently makes a weird high pitched noise a little that sounds like the tensioner/belt needs to be replaced (I had done this previously at ~65k about 2 years ago. I'm at around 81.5k miles now sounds similar to before when I changed it). What are the normal side effects/tell tell signs that I need to change em.
2. I have a 2013 335i xdrive coupe e92. Anything that I would have to do differently on my specific model?
Thanks in advance!
Did you ever find an answer to this? I'm at 82k miles and this has never been done so I'm wondering what I should keep an eye out for
Can someone tell me why do we need to change this? What are the symptoms?
i need help and i want to know if you can help me.
i have bmw f30 320i 184hp
Hello, what's he belt number for BMW 535I GT 2010??
Same process for the s55?
Hood safety catch delete?
I know this isn't really the car's you guys work on but I have a 2003 chevy s10 xtreme and I want to upgrade the head unit and temp controls, any tips on what to get?
Danny Rosillo Yeah, get a BMW. Or visit crutchfield.com to find a radio and install kit that you like.
How much play is acceptable? Mine is rattling sort of like yours but I just replaced the belt and tensioner last year
great question! mine moves too.
tensioner bolt is stripped any ideas?
Mine was making noise around 40k and had mine replaced then. Would you recommend doing another one at 80k?
What kind of noise did it make?
just done tha on my 335i f30, much better my tensionner was shaking like this at 64k km
Same process for e92?
Can this Tensioner throw a drive train malfunction light? Mine just did after a pull
Now my car lost some power. Turned off, restarted and check engine lights/msg went away
how is your oil filter gasket, my car is 65k km and its for change, also how often do you change your belt and belt tensioner.
Just got my gasket done at 77k. worth it. $880 for it though... that wasn't fun! does your tensioner have play? mine does, is this normal?
That's funny cause i just replaced my bmw 535i f10 M-Sport belt tensioner, two idler pulleys & German serpentine belt all OEM, yet my tensioner pulley still shakes as the new belt vibrates next to it so urs on this video seems normal. The problem with the old tensioner was that not only did it vibrated more than the new one but it also made bearing noise!
When the lettering on the old belt shows fading, then it's time for a new one!
Hey was your idler pulleys hard to change ? I have the same car and by the looks of it, it looks like there’s hoses in the way on the upper idler pulley.
This. I changed my tensioner pulley recently since my old one shakes like what’s in the video. Then new one goes in and it was steady for a few days then it shakes again. So the shakes are normal as long as it doesn’t make any weird noise.
Hey i have an x5 with the n55 will ur kit fit on it
I just did this today on my f15 n55 . No issues same process. Just have to remove the fan. Super easy.
I was literally just thinking about doing this to my 335i
Brownhash why? What are the symptoms of the car for us to change this?
Diego Carmona My 2015 335i is at 90k miles and I’ve noticed rapid movement on the tensioner.
Mine moves a bit like this one. is that normal?
Been following you for a long time brother ! Y'all inspired me to do the mods on my 328d. Been thinking of doing a channel for the diesel part of the F30 ! Any advice or help would be immensely appreciated !! 💪🏻💪🏻
#F30inWashingtonState 😂
What can happen if this really fails?
What happens if my tensioner is still wobbling after the new one is installed?
faulty part, there should be no woble at all
I have a b58 340i and just noticed my tensioner pully is moving to the right when revving it.. Only when i rev it. Its a 5/2018 model with only 22.000kms? is this normal?
Every tensioner will move when you rev it. When you rev it, the tensioner moves and makes the belt tighter. If that makes sense.
This is normal. I don think ant B58 has shown this as an issue yet. Surely eventually, but that engine is built much better than most older BMWs
@@NoClutchGarage im gonna try send you a video of it.. but has been 2 months now, its still doing good, but i have a feeling its wiggling a lil bit.. cold and warm, i just subbed btw ;)
Would this apply to the S55 engine as well?
I think so. almost the same design, but the S55 is closed deck, and some other changes, better rod bearings in the S55, later N55s (2014+) are using those better bearings as well. overall, a good design.
The bearing of my tentioner got stuck and my belt blew up...
So the only symptom is a shaky belt? No other indications like battery not charging? How much is the kit?
Jack Sampson battery not charging is a good indication too 😂
@@Rushfan102 yes. lol wait can it cause the belt go break?
My tensioner was shaking too, so I just did this maintenance job and to save some people time and money: it did absolutely nothing. The new tensioner may be shiny fresh but it's shaking as much as the old one.
really!? wow. My old one shakes a bit. can I just live with it? or do you think it will break? or cause issues?
I feel it was my fault....I drove it wayyyyyyy to hard. Redlined it all the time, took it to the track and gave it to my 16 year old neighbor. Sorry...whooooops!!
damn lol
38 Nm in Pounds???
So much harder than it looks.
Stripped the e12 somehow. Hopefully tightened it enough, but torque wrench never clicked
Gave up on removing the pulley, the t50 was getting twisted without any give from the bolt. So said f it I'll leave the existing pulley on.
To late watching this video it just happened to my 2011 bmw 335i!!!!
well I am already doing an maintenance overhaul already lol
