Featuring an internal fan, this alternator maintains optimal operating temperatures by efficiently dissipating heat during operation. The clockwise rotation direction matches the original equipment specifications for these Nissan models. The included pulley has six grooves designed for serpentine belts, which are common in modern engine configurations. An internal voltage regulator maintains consistent electrical output, protecting your vehicle's electrical system from voltage fluctuations. Additionally, the decoupled or clutch pulley reduces stress on the belt system, enhancing longevity and reducing noise.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for failing or worn alternators in Nissan Altima and Sentra\u003c\/li\u003e\n\u003cli\u003eResolves charging system failures causing battery drain\u003c\/li\u003e\n\u003cli\u003eAddresses electrical system malfunctions due to voltage irregularities\u003c\/li\u003e\n\u003cli\u003eEliminates belt slippage and noise related to pulley wear\u003c\/li\u003e\n\u003cli\u003eImproves starting reliability and overall electrical performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the WAI 13939N alternator, ensure the serpentine belt is properly aligned with the 6-groove pulley.
