Keep the alternator, air conditioning compressor, and other belt-driven accessories turning under steady tension with the SKP Accessory Drive Belt Tensioner Assembly (SK39384). This serpentine belt tensioner drops in as a direct-fit replacement for the 2013-2018 Nissan Altima, 2016-2023 Nissan Maxima, 2013-2024 Nissan Pathfinder, 2015-2024 Nissan Murano, 2013-2015 and 2017 Nissan Quest, 2013 Infiniti JX35, and 2014-2020 and 2022-2024 Infiniti QX60 — all with the V6-3.5L engine.
The tensioner applies and holds the correct load on the accessory drive belt so it doesn't slip. If a worn or failing tensioner is behind belt squeal or chirp, belt slippage, or a wobbling tensioner pulley, replacing it with this assembly addresses that cause. Diagnose the source of the noise before replacing, since a worn belt or another accessory can produce similar symptoms. Country of origin: China.
