dealer says this is a 4hr job I did it at home without a lift in 1.5hrs detailed how to remove and install serpentine accessory drive belt on Cla-250 and Gla-250 model Mercedes benz

For anyone watching, you could save yourself a lot of work disassembling by either using a long screwdriver or a speciality m270 belt tool which allows you to detention the belt from below. Great video showing how everything works and the routing of the belt tho!

[@tykusp7672]

is it possible to route the belt from below though? or will you need to remove the top to get to the top pulley?

[@SquilloS]

@@tykusp7672 I replaced my serpentine belt and idler pulley last night and did it all from the bottom of the car ( CLA 45 ) not gonna lie it was a pain in the ass but I got it within an hour just takes a little patience.

@@SquilloS how long was the screwdriver about bro?

[@leonidas9969]

Tech here just did one of these today I took off the oil cover and chassis brace, cut the belt , used a prybar to move the tensioner, used a 3mm Allen to lock the tensioner then install the belt it’s tight but can be done, actually today June 13 I modified that Allen welded a battery hold down bracket rod so it’s 10 inches longer makes life easier especially for these damn fwd euros bad design

I could not even change a belt with 2 hands, and you did it 1 handed 👏👏

[@JuniorVasquez-e1x]

Knock the but out of the socket and put a wrench on it was the best way I found to avoid the bit stripping out of the tensioner, some commenters said they avoided removing the motor mounts, I would recommend doing it the way shown in the video to save time and headache.

[@elonmusk8667]

Thanks for the video! I learned something today. To remove the old belt, you can just cut it.

[@fsdtdot361]

I did that belt today.... without opening anything at the top... I moved the tensioner back with long screwdriver

Always tricks to get things done easier than intended, good job.

[@jedidiahjohnson1874]

How??

[@diymadness8668]

Your way of work and work environment is quite similar to mine.

[@Bri-ez7od]

Bless. Your. Heart. For making this video. Lol. Much appreciated.

[@EvangelistKia]

I'm almost regretting getting this car

[@chino3058]

I’m having this done today at the dealership for $500 on my cla250 😭😭...the belt is around $20 and the rest is labor😤

[@streamlinebuilds1490]

Dang that's a spendy belt but it is a pain to replace.

[@rebelreloading5265]

That’s criminal

[@gobofragli]

Thanks for excellent vid!

[@butterfly77330]

Is this the same process for the 2016 cla45 Amg ? I can’t find anything on that model

[@streamlinebuilds1490]

Sorry I never worked on cla45

[@butterfly77330]

Thank you

[@were2006]

Do you have a video of the noise that this way making before disassembly? Thanks in advance

[@streamlinebuilds1490]

Sorry I did not! But it was just a chirping and loud squealing noise that I assumed was a bearing.

[@jamarmckay5514]

I need to remove the alternator

[@allanialex]

I have the CLA45 and it makes a chirping noise when the engine is hot, also the engine seems to overheat a bit and causing the fan to kick in super loud sounds like a jet just to cool the engine down, could this be water pump? Any help would be appreciated

[@streamlinebuilds1490]

Sounds like the chirping would be from the belt. The water pump has a thermostat attached to it and night be easy to start by changing the thermostat first.

[@AUTOPERFORMS]

I have a question about after the installation you hear noise like hitting something every time you start the engine or change gear ⚙️ I don’t know if you have this problem too ?

[@streamlinebuilds1490]

Sorry I'm not sure what that could be, something must not have been tightened up.

[@AUTOPERFORMS]

@@streamlinebuilds1490 when you use the jack to rise up engine and bring it back down that would cause any damage to the engine support ?

[@mytwogoodhands2799]

Only a stupid Engineer would require that parts come off to change a belt! Buy American!

[@vikingrobot4179]

Mercedes’ engineers don’t think about the guys that repair them. They think about how efficiently we can stuff an engine made with inferior parts into a very small hole as quickly as possible on the assembly line…screw the guys that work on it and the customers that buy these pile of crap European taxi’s. I’ve been working in Mercedes’ junk for 30 years and I can attest that they are piles of crap compared to a ford ranger or econoline. Mercedes are over rated piles of crap. Yes the AMG models are fast hell and handle fairly well but there’s so much crap stuffed in them they spend more time in the shop than on the road ….if they get driven.
