Remy 91520 Alternator

Remy 91520 Alternator Overview

The Remy 91520 is a new 12-volt alternator built for charging-system replacement on select GM vehicles. It delivers 105 amps, uses an internal fan and internal voltage regulator, and includes the pulley for a direct-fit service replacement.

Compatible With 1997-1999 Chevrolet Malibu and 1997-1998 Oldsmobile Cutlass applications, this alternator is a practical choice when the original unit is no longer maintaining proper system voltage. It also cross-references Delco/Delphi OE numbers 10464097 and 10464401 for the same application.

Detailed Product Description

Remy 91520 is a new alternator engineered for vehicles that require a 105-amp charging output and clockwise rotation. The internal regulator and internal fan support a compact OE-style design, while the included pulley helps match the original accessory drive configuration. For shoppers searching for a 1997 Chevrolet Malibu alternator, 1998 Oldsmobile Cutlass alternator, or a 1999 Pontiac Grand Am charging replacement, this unit covers the listed applications with the correct electrical specifications.

Use this alternator when replacing a worn charging unit on 1997 Chevrolet Malibu and 1997 Oldsmobile Cutlass models with threaded mounting foot, or on 1998 Chevrolet Malibu and 1998 Oldsmobile Cutlass vehicles that require a 105-amp unit. The Remy 91520 also applies to 1999 Oldsmobile Alero and 1999 Pontiac Grand Am vehicles, with the note that it is not compatible with vehicles with less than 105 amps capacity.

What It Helps Fix

• Low battery charging caused by a failing alternator
• Dim lights or electrical load issues from weak output
• Battery warning light concerns related to charging-system faults
• Voltage instability from a worn internal regulator
• Driveability problems tied to insufficient alternator output

Installation Notes and Tips

Verify the vehicle’s charging-system requirements before installation, especially on 1999 Oldsmobile Alero and 1999 Pontiac Grand Am models, which require at least 105 amps capacity. Confirm clockwise rotation, 12-volt system voltage, and pulley alignment before mounting. For 1997 Chevrolet Malibu and 1997 Oldsmobile Cutlass applications, the fitment notes specify a threaded mounting foot.

Always compare the original unit’s connector, mounting style, and output rating to the replacement alternator before installation. After installation, check charging voltage at the battery and inspect belt tracking to confirm proper operation.

Quality Assurance

Remy’s New line is built as a new replacement component for OE-style service applications. This alternator is referenced to Delco/Delphi original equipment numbers and is specified with the correct amperage, regulator type, rotation, and pulley configuration for the listed vehicles.
