What this part does
The alternator generates electrical power to operate the vehicle's electrical systems and recharge the battery while the engine is running. It mounts to the front of the engine block and is driven by the main accessory serpentine belt. When this component fails, the vehicle will run exclusively on battery reserve power until depleted, resulting in a stall, dimming lights, and an illuminated battery warning indicator on the instrument cluster.

Before you order
Verify the amperage rating on the data plate of your original unit, as these vehicles were equipped with either 80-amp, 90-amp, or 140-amp variants depending on the factory electrical options (such as heated seats or premium audio). It is highly recommended to inspect and replace the serpentine belt, idler pulleys, and belt tensioner during installation, as worn drive components are a primary cause of premature charging system failure.
