Benefits and Features
- OEM-Compatible Design: Manufactured to Valeo standards for form, fit and function on compatible Citroën and Peugeot models.
- Efficient Charging: Maintains stable charging voltage under load to protect vehicle electronics and battery life.
- Multiple Reference Numbers: Useful for fast identification in parts catalogs and online searches (see Technical Information).
- Ready For Workshop Fitment: Designed for straightforward replacement with common garage tools.
How To Replace
Replacement of the alternator is a routine job for a trained mechanic and manageable for experienced DIYers with the right tools. Typical steps:
- Disconnect the negative battery terminal before starting to avoid short circuits.
- Release belt tension and remove the drive belt from the alternator pulley.
- Disconnect electrical connectors and battery output cable from the alternator.
- Remove mounting bolts and extract the old unit. Inspect the belt, tensioner and pulley for wear.
- Fit the new alternator, secure mounting bolts to the manufacturer’s recommended torque, reconnect wiring and refit the belt with correct tension.
- Reconnect the battery and verify charging system operation (engine running, typical charging voltage around 13.8–14.6 V).

Installation Recommendations
- Always disconnect the battery before removal or installation to prevent electrical damage.
- Inspect and, if necessary, replace the drive belt, belt tensioner and any worn pulleys during alternator replacement.
- Use correct torque values for mounting bolts and ensure secure, clean electrical connections to avoid poor contact or heating.
- After installation perform a charging-system test with a multimeter or diagnostic tool; verify charging voltage and alternator output under load.
- If vehicle has advanced charging management (start-stop or CAN-controlled charging), perform post-installation checks with appropriate diagnostic equipment.
Why The Part Most Commonly Fails
- Wear Of Internal Components: Brushes and slip rings wear over time, reducing charging efficiency.
- Bearing Failure: Worn bearings produce noise and can seize, leading to pulley and belt damage.
- Voltage Regulator Malfunction: Internal regulator failure causes undercharging or overcharging, risking battery and electronics.
- Contamination And Overheating: Oil, coolant leaks or excessive heat shorten alternator life and damage internal parts.
- Electrical Overload And Poor Connections: Corroded terminals or heavy parasitic loads accelerate failure.
Typical Service Life: Service life varies with vehicle use and maintenance but alternators commonly last in the range of 100,000–200,000 km. Regular inspection of belts, electrical connections and cooling paths helps extend life.
