Customer Question
2006 C230 whinning at...

2006 C230 whinning at first. I sprayed the pulleys with belt dressing. Now almost immediately its making a clanking noise

Mechanic's Assistant: Which belt is acting up? And when was it last changed?

I bought it 5 yrs ago. I have never changed the belt. It looks like it is the left upper pulley or maybe larger one one below it

Mechanic's Assistant: Are you fixing your C230 yourself? What have you tried so far?

I sprayed water on each pulley and belt dressing

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

As i accelerate it gets somewhat quieter, the clanging noise
