New Belt Tensioner Assembly fits various Nissan and Infiniti models equipped with a VQ35HR or VQ37VHR powertrain. This component is a lower cost alterntive to the OEM Belt Tensioner, letting you keep a few extra bucks in your wallet for future modifications!
Located on the front of the motor in your HR /VHR, this belt tensioner provides the belt a smooth surface to spin across while providing the proper amount of belt tension. As the bearings in the pulley wear, you may begin to experience 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. In addition, internal springs on the tensioner become loose overtime, in some cases leading to belt slip/squealing.
NOTE: Whenever idler or tensioner pulleys are replaced due to faliure, it is important to carefully inspect the belt for excessive wear. New OEM drive belts can be purchased in their respective links below if necessary.
