The serpentine belt tensioner and idler pulleys will need to be replaced when replacing the belt. The tensioner will not hold tension on the belt and the pulleys may be worn and allowed the belt to ride off. I recommend having a qualified mechanic, like one from YourMechanic, come and check the problem for you and give you a diagnosis.
