WAI 21152N Alternator

Overview

This WAI alternator, part number 21152N, is a new 150 amp charging unit built for modern electrical loads. It uses an internal regulator, internal fan, and a serpentine pulley setup to support stable charging performance in the correct applications.

Compatible With Nissan Maxima, Nissan Pathfinder, Nissan Murano, and INFINITI QX60 applications listed below, this 21152N alternator is a direct-fit replacement for vehicles that require the specified Mitsubishi family design and clockwise rotation.

Key Features

• 100% new construction, not remanufactured.
• 150 amp output for higher electrical demand.
• Internal regulator and internal fan design.
• 7-groove pulley for serpentine belt systems.
• Clockwise rotation with no clutch pulley.

Detailed Description

WAI builds this alternator to deliver the amperage needed for today’s vehicle electrical systems. The 21152N uses proprietary components and manufacturing processes, and its Mitsubishi family design supports the fitment requirements shown for Nissan Maxima, Nissan Pathfinder, Nissan Murano, and INFINITI QX60 applications. If you are replacing a worn charging unit, this alternator provides the specified output and pulley configuration for the listed vehicles.

This part cross-references Dorman - HELP (e.g., 21152) for the same application.

Common Uses

• Charging system failure caused by low or unstable output.
• Battery warning light related to alternator performance.
• Electrical accessory issues from insufficient amperage.
• Noise or charging problems tied to pulley or internal component wear.
• Replacement for a failed factory-style alternator in the listed applications.

Installation Notes

Verify the amperage rating, pulley groove count, belt type, rotation direction, and regulator style before installation. Confirm the vehicle’s build date where noted, since some applications are limited to specific production ranges. Match the part number 21152N to the required charging system specification before ordering.

Quality Assurance

WAI states that this alternator is 100% new and manufactured with proprietary components and processes to support long service life and consistent performance.
