Product Details

Remy Premium Remanufactured 20320 is built as an OE-style charging system replacement for select Buick Skylark, Oldsmobile Achieva, and Pontiac Grand Am models. The remanufactured construction supports proper electrical output for vehicles that call for a 105-amp alternator, while the internal regulator helps maintain stable charging performance in normal driving conditions. This part cross-references Delco/Delphi applications such as 10463401 and 10480114 for the same application.

Common Problems This Part Can Address

• Battery warning light caused by alternator output loss
• Low charging voltage at the battery
• Dim lights or electrical instability during operation
• Charging system failure on 105-amp equipped vehicles
• Noise or wear related to a failing alternator assembly

Installation Notes and Tips

Verify that the vehicle is equipped with a 105-amp charging system before ordering. This alternator is not compatible with vehicles with less than 105 amps capacity. Confirm pulley alignment, rotation direction, and electrical connector match the original unit before installation. For best results, inspect the battery, belt condition, and charging circuit connections during replacement.
