I have that problem with the odd car and all I do is spray some WD40 on to the belts that solves the problem (Except for when it is a bearing or air con compressor problem)
it could be your pulley that keeps tension on your belt or it could be a belt
replace the belt with a goodyear bet
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley. Pry the idler back and remove the belt.If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley.

put it on the tension srewand push back towards muffler
The tension pulley should have a bolt that holds it on, allowing you to replace the unit.
Most likely the new pulley is not in line with the rest.
It will be one of the smooth ones with no ribs.
tension pulley is an automatic tensioner that keeps the serpentine belt at the proper tension it is a single pulley that is smooth (no grooves) usually turning clockwise with constant pressure loosens pulley for belt removal use caution pulley is spring loaded
I the belt looks good, use some belt dressing and start car again. if squeal stops, belt is loose, so replace tensioner. If it still squeals, could be a bearing on any pulley, then you will have to isolate with a mechanic stethoscope or try wd40 on each one by one. If it improves, you found the culprit.
you dont adjust a tension pulley you adjust the position of the compressor to tighten the belt
u need to relaese tension on the tension pulley. this is usually done with a long socket wrench handle. when u release tension and remove belt you then release tension on pulley until you have routed new belt . you then move tension pulley again until you can put belt on it, then release pulley and it will automatically provide correct tension
