OEM 2011-2018 Infiniti M37 / Q70 Smooth Idler Pulley.

Located on the front of the VQ37, the idler pulley is responsible for guiding and maintaining tension with the drive belt. 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.

There are three idler pulleys on the front of your VQ37VHR. This pulley, identified as the 'smooth' is shown in the parts diagram provided.
