Belt/Pulley Question

Belt/Pulley Question
Recently my car started making a high-pitched whistling/whining noise that belt dressing did not fix. My question is this...when facing the engine, what is the bottom left pulley attached to (what does it do - the one attached to the bottom of the engine block)? All of the other pulleys that have bolts on them are still, but the bottom left pulley is vibrating/turning so that the bolt is definitely not still. Is the bolt supposed to turn with the pulley? If not, do I just need to turn the bolt (if so, to what torque)? Any other suggestions as to what could be causing this noise?
Thank you in advance for any help.
