About this part

This is a new alternator built to replace the Delco unit on the Impala. It is rated at 105 amps. The alternator charges the battery while you drive and supplies power to the ignition, lights and accessories. A failing unit can cause a dead battery, a battery or voltage warning, and dim headlights at idle. Being new, it does not involve a core exchange.

Fitment notes

The catalog lists 15400N for the 2003 Chevrolet Impala with the 3.4L V6. The 3.8L V6 is not part of this listing. Compare the amp rating on your old alternator before ordering. Our fitment table may not be complete, so check your Impala there or send us your VIN.
