ALTERNATOR BELT ADJUSTMENT
Application …(1) Deflection - In. (mm)
240SX … 1/4 (6)
(1) - Deflection is with 22 lbs. (10 kg) pressure applied midway on the longest belt run.
or too loose… it will squeek if its too loose too. probably this over too tight… for it to squeek from to tight your fucking soemthing up… too loose the belt just slips

Belt may be dry.
Try spitting on it
battery could be going and it’s always losing enough charge to put extra strain on the alternator causing it to resist more and slip… which makes it intermittent, and even if perfectly adjusted will still squeal sometimes
this was constantly happening on my p.o.s. until I upgraded from a 65a to 100a alternator… now it never happens because my battery is never low
