When the alternator fails, your battery will drain, electrical systems will malfunction, and eventually your vehicle won't start or run.
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.
