2002 automatic megane engine noise

He has Correa, they already changed it, but I realized that the noise is because of the entered it comes from a small piece that is in the middle of the pulleys, the piece moves when the belt rotates.

My husband has just checked the car set it and realized that the noise it makes in the morning is because of the engine that after 5 to 10 minutes disappears, but it has the slight wake that apparently comes from the engine

The piece that moves when the band (Correa) tour is the tensioning pulley, the pulley has to be changed since the buller that has that pulley is run out of fat.

And the engine noise can be identified rather with a hose (one end to the ear and the other to the part where the noise is heard), as caution the hose do not put it near the pulleys or the fan.

Thanks a lot

Have you already repaired your car ?? What was noise ??
