ACDelco GM Original Equipment Light Duty Remanufactured Alternators are GM-recommended replacement for your vehicle's original alternator. Alternators provide power to your vehicle's electrical systems and charge the battery while the engine is running. ACDelco GM Original Equipment Light Duty Remanufactured Alternators are engineered for virtually every make and model of GM car, light duty truck, and sport utility vehicle. Remanufacturing alternators is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. These alternators have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Customer Questions
Will the alternator drain my battery?

How do alternators work?
Alternators convert mechanical energy from the engine into electrical energy to power the vehicle's electrical system and charge the battery. They consist of a rotor, stator, and voltage regulator, which work together to produce electrical energy that is used to power the vehicle's electrical components and charge the battery.
Which alternator do I need?
To determine which alternator you need, consider your vehicle's make and model, engine size, and electrical system requirements.
Which alternator system is controlled by the PCM?
