About the Chevrolet Impala Alternator (ALT/GENERATOR)
The alternator is your vehicle's electrical generator, converting mechanical energy from the engine into electrical power to charge the battery and run all electrical systems while driving. When the alternator fails, your battery will drain, electrical systems will malfunction, and eventually your vehicle won't start or run. The Alternator (also known as ALT, GENERATOR) is a critical component for your Chevrolet Impala.

Replacement Info
Alternator replacement is a moderate DIY job accessible to most home mechanics. The alternator is typically mounted on the front of the engine, driven by the serpentine belt. Replacement involves: disconnecting the battery, removing the belt tensioner to release belt tension, disconnecting electrical connections, unbolting the alternator, and reversing the process with the new unit. Most replacements take 1-2 hours. Some vehicles have alternators in difficult locations requiring additional component removal.
