Serpentine belts have a self tensioner and if it is too loose then either the belt has streatched and needs replacing or the tensioner is bad and needs replacing. There is no adjustment.
If it is a new belt they do make two sizes based on which alternator you have I guessed on mine and was wrong, it was almost the right size but would slip alot.

With a wrench
try tightening the tension pully works like a charm
If it has a serpentine belt should be done by tensioner unless it is defective
