Re: Pulley noise?
If the noise goes away or is reduced after using belt dressing, even for a few
minutes, it is likely the belt is the source of the squealing. I would
replace the belt and see what happens. At worst, you will have an emergency
spare in case something goes wrong with the new one.

Hmm.. Sometimes pulleys can get out of line, check your vibration
damper and see if it's shifted on the rubber isolator.
I've gotten squeeky belts before due to fine dust/salt being packed
into the belt. Only fix was a new belt.

Re: Pulley noise?
The idler pulley can be the source easily. Maybe you can get some oil
on the bushing, but I couldn't on the last couple I have seen. Well, I
got some WD40 with the straw on it into one and the noise dropped, so it
was replacement time.
The replacement part is three different things that have to be ordered
separate. The bushing, the washer and the bolt.
A dirty cable end can also make the alternator suck big time and need HP
big time after a start so the belt slips. Dressing won't help that.
I test mine by going out with a cold off engine and trying to hand slip
the alternator pulley. If I can slip it, it either is loose or it had
'shined' up. The alternator needs several HP to spin up under load and
if you can hand spin it, it will slip.
If that is the case, I need a new belt. I go through 3 or more
alternator belts a year when I am running mud pits. Mud equals liquid
sandpaper and will polish the belt up real sweet.
