Installation Notes
Recommended general replacement steps (for qualified personnel): disconnect the negative battery terminal; release belt tension and remove the drive belt; disconnect electrical connectors and unplug the alternator; remove mounting bolts and extract the alternator; install the replacement unit, secure mounting bolts to manufacturer torque specifications, reconnect wiring, refit the drive belt and set proper tension, reconnect the battery and verify charging voltage (typically around 13.8–14.6V at idle). Refer to the vehicle workshop manual for exact procedures and torque values.
Common Failure Modes & Service Life
Alternators commonly fail due to worn brushes, faulty diodes or voltage regulators, bearing wear, contamination, or overheating caused by poor ventilation or incorrect belt tension. Typical service life varies with use and conditions, often occurring in the range of 80,000–150,000 km, but this can be shorter in vehicles with heavy electrical loads or intermittent charging issues. Symptoms of a failing alternator include dimming lights, battery warning lamp illumination, slow cranking, or repeated battery drain.
