Product Details

Remy 12570 is a remanufactured alternator engineered for direct replacement in select Nissan Maxima, Nissan Murano, INFINITI I30, and INFINITI I35 applications. This unit follows the OE-style Hitachi configuration and is specified with 110 amps, making it a practical choice for restoring charging output when the original alternator is no longer maintaining proper system voltage. The Remy Premium Remanufactured line focuses on replacement parts built around OE application requirements, and this alternator is configured with an internal regulator and internal fan for a compact, integrated design.

This part cross-references Hitachi-style OE numbers such as 23100-2Y900 and 23100-CN100 for the same application. The Remy 12570 alternator is a fitment-based replacement for 2000-2003 Nissan Maxima, 2003-2007 Nissan Murano, 2000-2001 INFINITI I30, and 2002-2004 INFINITI I35.

What It Helps Fix

• Low battery charging caused by a worn alternator
• Battery warning light or charging-system warning on the dash
• Dim headlights or unstable electrical output
• Accessory performance issues tied to weak system voltage
• Starting problems caused by insufficient alternator output

Installation Notes and Tips

Verify the OE part number, pulley configuration, rotation direction, and amperage rating before installation. Confirm the vehicle uses a 12V charging system with an internal regulator and Hitachi-style alternator layout. For best results, inspect the battery, drive belt, belt tensioner, and charging cables before installing the replacement alternator. Fitment includes 2000-2003 Nissan Maxima, 2003-2007 Nissan Murano, 2000-2001 INFINITI I30, and 2002-2004 INFINITI I35.
