Key Features

• 110 amp amperage rating for OE-style charging output
• 12V alternator with internal voltage regulator
• Clutch pulley included; 6-groove serpentine belt design
• Clockwise rotation with internal cooling fan
• Negative polarity and 2 o'clock plug clock position
• OE manufacturer reference: Mitsibishi

Product Details

This BBB Industries REMAN ALTERNATOR line part is built around the specifications commonly used in late-model Nissan charging systems. Part number 11657 features a 52 mm (2-1/16 in.) outside pulley diameter, air cooling, and a decoupled clutch pulley to help maintain stable belt drive behavior under changing engine speeds. It cross-references A2TJ1881 and A2TJ2381 for the same application. For buyers searching by vehicle, this alternator is a direct match for 2018 Nissan Altima charging-system service and also covers 2014-2018 Nissan Altima applications listed below. The BBB Industries 11657 reman alternator is a practical OE-style replacement when the original unit no longer maintains proper charging output.

• Low battery charging caused by a worn alternator
• Battery warning light triggered by charging-system failure
• Dim lights or electrical instability at idle
• Noise or belt drive concerns related to a failing pulley assembly
• Intermittent charging output on Nissan Altima models

Installation Notes and Tips

Verify the amperage rating, pulley style, plug clock position, and rotation direction before installation. Confirm the vehicle build date for 2018 Nissan Altima applications, since fitment is split between units built to 09/2017 and from 09/2017. Inspect the serpentine belt, belt tensioner, and charging cables during replacement to help avoid repeat charging-system issues.

Quality Assurance
