@@officialnolimitstv Question 🙋🏼‍♀️ I have a 08 c300 4matic sport my serpentine belt broke we replaced the upper grooved pulley. Then the pulley shredded after driving it around the block but the belt did not, this happened twice. So we replaced both idler pulleys and the tensioner pulley yesterday drove it around the block and the same thing happened. The grooved upper pulley shredded but the belt did not break. Do you have any idea of what is causing it? I was told the tension pulley on my car adjust automatically.

@@shellywindell7302 have you check all the other pulleys for damages? I recommend to take off the belt and check the pulleys by hand check for damages and give them a spin to see if they aren't seized.

@@officialnolimitstv Thank you so much for responding! They all spin the only one that doesn’t spin all the way around and feels tighter then the others is the water pump pulley. Which that’s being delivered tomorrow.
