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.
