Thank you. This is great. My car started makind some grinding noises when the engines runs so I can now replace a few parts and see if it goes away. Looking at parts it seems like just replacing the pulley on the tensioner and leaving the old tensioner in place is an option. Can you say why you chose to replace the entire assembly?
Hey Christian! It’s been a while since I did this video but it was likely because it all came together as a kit. Belt, tensioner and pulleys. It is usually cheaper when you buy the kit.
Great video! I was wondering if you know how to remove the engine fan? I've got a bad alternator and I'm stuck on getting the fan out without spilling coolant everywhere.

@@512TXSDIY yes. I replaced mine the other day but it moves around (where the notches are in the top) almost like adhusting itself as the flex of the belt changes
Hey 512TXS.. I hear a belt chirping noise only on a cold start/goes away after a few minutes, trying to diagnose the issue.. what necessitated the repair in this video?
That chirp is the start of a bad drive belt (i.e., serpentine belt) in my opinion. Physically look at it to see if there is wear and of course replace if needed. This is a pretty easy DIY as well if you decide to do the pulleys, belt tensioner, etc. - they sell whole kits.
Great video. I replaced all the two pulleys,tensioner and belt on my 2015 glk350. Now it's squealing all the time as i drive. What do you think might be the problem? Thanks
@@512TXSDIY replaced everything but i think it's the PCV valve making the squealing noise according to other videos i watched. The problem is how to get to it.
I have some notes from a mechanic about what happened with my car, but they're trying to charge almost $4K to fix it. Doesn't seem right. Another mechanic told me he could fix it way cheaper but he needed a special tool to do the below job that he doesn't have. I'm trying to figure out what tool he would need. - the serpentine belt came off and broke sensors /wires under the pulley - the serpentine belt is wedged/stuck between the pulley and front timing cover - need special tools to get the pulley off to get from the timing cover - has to replace: power steering pump, sensors, belt What pulley do you think the mechanic is referring to? What special do you think is needed for this job that a non-benz mechanic wouldn't have?
Thank you for the comment. I am not sure what special tool they are referring to. The only "special tool" I can think of is the reverse Torx bit, which isn't common. I had to get mine on line.
Got mine on eBay for under $60. Do a quick search there and you should be in good shape. Don’t forget to like and subscribe if you haven’t already. Lots of content on the GLK here :-).
If it just started you’re probably fine but it should 100% be addressed. If the belt snaps, you won’t have power steering, AC/heat, etc. and could overheat.
@@512TXSDIY That is really good. I ended up going with FCP Euro and spending around $110 since I included a belt as well. What size allen key do you use to keep the tensioner loose?
@@isidroalcantara9409 Wow! That’s a great deal if it came with the belt. Well done. I believe it was an 8 mm key but really, you can use any of the smaller sizes just to hold it in place.
It looks so simple and easy to access not sure why the Mercedes Benz dealership charging me 700$ to replace the belt and the belt tensioner 🙄.... I understand it's the DEALERSHIP but that's the only ones I let TOUCH my car 🤣 Prices been reasonable , but this one the first time I felt like this was a ridiculously high amount, like look how simple that looks to change and it's not like it's hard to get to which means less labor 👍 So not sure where the 700$ come from 🙄
Thank you for the comment Mrs. Rose. There are good dealers out there for sure but some simply overcharge. I do know they normally have higher operating expenses and as a result, must charge more to cover the shop. I’m happy out got fixed for you though. Great cars!

If you’re buying OEM parts, that could add to the costs as well. $1,200 is crazy but it’s a luxury tax I guess. You can certainly save some money if you do it yourself. I don’t mind aftermarket parts. Except electronically components... then I’d get oem. Don’t forget to like, share, and subscribe if you haven’t also.

Good job. I have to do this tomorrow. Thanks for video.
You’re welcome and good luck. Take your time.
Have you changed or even reused the washer ring that comes first to the engine?
Mine came with new hardware so I used the kit

Does the idler tension suppose to move when the car is running or stay still and spin
It will flex a little when it’s on so that’s not a problem. Don’t forget to click the like button and hit subscribe if you haven’t already.

How did aftermarket part hold up with time? Trying to decide oem vs aftermarket pulley kit and belt.
Great!!!

How do I remove the pin after install ? My 17mm won’t move the tensioner anymore
I was able to pull mine out…
I’ve change this pulley at least 5 times in 12 years. Hope I’m doing something right.

Should the tensioner wobbly slightly under load?
Yes - you mean when it’s running correct??
@@512TXSDIY yes. I replaced mine the other day but it moves around (where the notches are in the top) almost like adhusting itself as the flex of the belt changes
@@jamesulbot it is normal for it to move when under load and running. It will flex more when you step on gas too.
Donde puedo saber los pares de apriete de los tornillos?
I don’t have it, sorry
Is made of nylon the first pulley that you replaced?
Nylon? I’m not sure what it’s made out of. I assume plastic. Don’t forget to like, share and subscribe to the channel of you haven’t already.

What did you torque your belt tensioner at
I don’t recall since this is an older video. Can someone else answer this?

what torque did you end up using on the second pulley and the tensioner?
Double check but I think this is it: Newton-meters 35 Nm
Foot-pounds: 25.81 ft-lb

Absolutely criminal that these places charge you so much for a 30 minute job? Do they really think their labor constitutes to $1200/hour?
