A loud squealing or chirping sound from under the hood, especially on cold starts or when accelerating, is the most common sign that your serpentine belt needs replacement.

A worn or slipping belt can affect the performance of these systems and leave you stranded.

This is a factory-original Subaru serpentine V-belt (OE part number 23780AA120), designed for the 2012–2015 Impreza and 2013–2015 XV Crosstrek with the 2.0L engine . It is manufactured to Subaru's strict quality standards. This is the same part sold at Subaru dealerships.
