OEM Serpentine Belt Tensioner for your 2013-2018 Nissan Altima equipped with QR25DE drivetrain.
OEM Belt Tensioner provides the belt a smooth surface to spin across while providing the proper amount of tension. As the bearings in the pulley wear, you may begin to hear a high pitch squeaking or squealing. Over time this may result in complete bearing failure, causing the pulley to lock up and break the belt.
Ensure optimal function and fitment with this Genuine Nissan replacement part.
