Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello, yesterday I started to hear this rare sound. It always sound, even engine is warmed. It sounded one day a week ago, but next day don't sounded. In the video the noise get more louder than it real sound, but it sound like an electric engine of a r.c. car more less. I put my ear next to the belt, but I'm not sure the noise come from it, I hear from all the engine. What do you think is? thanks. http://www.youtube.com/watch?v=p85bzy-3Mjg

POST 2Original post

Probably the pulley, I need to replace mine as well. It is noisy. BTW you can't tell by that video what it is.

POST 3Original post

Take off your serpentine belt and spin all the pulleys by hand to see if you can isolate the bad one.All you need is a 24mm socket, turn clockwise and your belt will slip right off. GL

Sorry, I don't understand very well how to procedure. where pulley should I put the 24mm socket? Can you link me to a tutorial or video how to make it?

POST 6 / ORIGINAL POSTEROriginal post

I remove the belt, and started the engine without it, but the noise doesn't dissapear.
