Detailed Description

Remy 91308 is an alternator for charging-system service on 1988 Buick Regal, 1988 Oldsmobile Cutlass Supreme, and 1988 Pontiac Grand Prix models listed in the fitment data. The unit is specified as a new replacement alternator with 105 amps of output, internal voltage regulation, and a clockwise rotation pattern. The square B+ terminal note is important for Buick Regal and Oldsmobile Cutlass Supreme applications, while Pontiac Grand Prix fitment is limited to vehicles with 105-amp capacity.

This part cross-references Delco/Delphi-style applications for the same use case. The Remy 91308 part number is also useful when matching replacement charging components by OE reference and electrical specification.

What It Helps Fix

• Low battery charging caused by alternator output loss
• Battery warning light concerns related to charging-system faults
• Dim lights or unstable electrical performance from weak charging voltage
• Charging issues on vehicles requiring a 105-amp alternator
• Replacement needs for a worn or failed factory alternator

Installation Notes and Tips

Verify the vehicle uses a 12V system, clockwise rotation, and the correct square B+ terminal configuration before installation. Confirm the application is equipped for 105 amps, especially on the 1988 Pontiac Grand Prix, since vehicles with less than 105 amps capacity are not listed as compatible. Match the pulley and regulator style to the original charging system layout, and compare the OE reference and connector details before final fitment.

Quality Assurance

Remy 91308 is a new alternator built to OE manufacturer reference Delco/Delphi specifications for the listed applications. Its internal regulator, external fan, and included pulley support a direct-replacement charging-system service approach.
