Detailed Description

INA FB7K407 is a serpentine belt used in front end auxiliary drive systems to transfer power to engine accessories such as the alternator, power steering pump, and air conditioning compressor, depending on the vehicle layout. INA’s FEAD-focused design approach emphasizes stable belt operation in tight installation spaces, which is important on modern engines that place greater demand on the accessory drive system. This part cross-references Gates K070407 for the same application. Compatible vehicle coverage includes 2013-2018 Nissan Altima, 2016-2018 Nissan Maxima, and 2014-2019 INFINITI QX60, along with additional Nissan and INFINITI applications listed below.

Installation Notes and Tips

Verify belt routing against the vehicle’s underhood diagram before installation. Inspect pulleys, tensioner operation, and accessory alignment at the same time, since worn components can shorten belt life. Confirm the exact application by year and model, especially for 2019 Nissan Maxima, Murano, and Pathfinder builds noted as valid through 09/01/2019. The FB7K407 part number should be matched to the vehicle’s OE reference before ordering.
