2002 Base 986 noise (front of engine)

Take the belt off and try again. If no noise = cause is something driven by the belt. If noise remains… probably timing chain / tensioner issue..

Sounds like water pump blades but it could be the alternator pulley.

Sounds like your alternator pulley to me. CTA 8088 (tool) and Bosch 1986AE0448 (pulley) should fix that right up.
