Default Alternator noise

my alternator went out about a week ago, i replaced it with a used one, everything went great and it was working fine,

yesterday i noticed a squeeking noise coming from my engine, the noise is coming from the alternator.... is there any way it can be lubed? a solution? the alternator is OEM.


any help would be great!

I put in a used eBay alternator in an Accord a few months ago and before we put it in I must have sprayed a half can of WD40 between the wheel base to make it stop whining. It never went away but quieted down considerably.

check the tension, assuming the S has an auto tensioner.

dont not use dressing or wd40 on belt, it could lead to premature cracking and it's not exactly a fix.

check the belt "slack" i think there's a spec in the manual that you could look up
