A worn decoupler can show up as a rattle, whirr or chirp from the belt drive, or as a fluttering belt. With the engine off and cool, look the pulley and belt over for wobble, cracks or damage. Belt noise can also come from the belt, tensioner or alternator, so find the cause first; a shop can test the pulley's free-wheeling.
