One of my belts on my '08 C300 Sport 4-matic is shredded. See photo of belt.

What part number is this? Looking to identity the belt and order online.

Anyone know how long it would take a local garage to install this belt?

 

should take about less than 15 mins to install.
it is the serpentine belt

 

Like shardul stated, it is a serpentine belt. You should be able to find this at any local auto parts store. Brand you have in it now should be a Gates which the stores should carry. Oreilly Auto Parts carries these belts for around $35 + tax.

 

FYI, check all your pulleys. That's not always but usually a sign the you might have a bad pulley.

 

Thank you all. Always impressed with the knowledge in this community.

 

Does the c300 sport use a 6 Rib?

I am going to purchase at this my local Auto Zone store but they have many different ones. See list. Not sure which one is best choice.

 

Did you add "my vehicle" to filter for yours?

Yes I added my vehicle but it displayed various ribs. I think it's 6 but wasn't sure. Any suggestions on the ones you listed is appreciated. I'll just pick one based on your input. Which one would you order?

 

Count the ribs, any belt will be better than the one you are running now, check pulleys for excess wobble and replace if they spin for a long time when flicked with your finger.

 

Thanks. I counted 6 ribs. Where are these pullys you speak of. Probably easy to just buy everything at once online. Just don't want to buy wrong ones. Thanks for the help.

 

Check the one at the top of your picture, the one to the right and the tensioner pulley. Remove the belt first then spin using your finger.
Not familiar with your tensioner setup, but do a search to release the tension to remove the belt, you have a picture to help when you replace the belt as far as routing. Any good auto parts store will have a belt for you, do not leave this go as the serpentine runs everything, alternator, water pump, power steering a Benz with no power steering is not a good day

 

Thank you all for the help. I bought the belt, went to shop, he said I needed one threaded pully. He ordered it and then told me price of $90 for the pully. I looked it up on my phone while waiting and the and the Advanced Auto Parts down the street had it for around $15. I asked if he ordered the correct part because $90 seemed like a lot. He said no. My bill to install just the belt was $70 and it took 20 min plus calls to get new pully. I will pick up the part from the Store for $15 later today and I am hoping this $70 charge includes the pully install but I doubt it. If its not included I will go elsewhere.

Thank you all for your help. I hope this helps others.
