Description
Valeo CL15 alternator for Citroën and Peugeot vehicles with 1.6 e-HDi and 2.0 HDi RH02 engines
The Valeo CL15 alternator is a direct-fit replacement unit commonly used on a range of Citroën and Peugeot diesel models with 1.6 e‑HDi and 2.0 HDi (RH02) engines. Designed to restore reliable charging performance, this alternator is often searched by its product numbers and OE references, making it a preferred choice for professional workshops and experienced DIY mechanics who need a quick, accurate part match.
What This Part Does
The alternator converts mechanical energy from the engine into electrical energy to charge the vehicle battery and power electrical systems while the engine is running. It supplies current to lights, ECU, heating/cooling fans, infotainment and charging circuits, and ensures stable system voltage during operation.
Typical Fitment
Compatible With (examples): Citroën C3 Picasso, Citroën C4 II, Citroën C4 Picasso, Citroën C8, Peugeot 3008 I, Peugeot 301, Peugeot 308, Peugeot 5008 I, Peugeot 807. Always check the part numbers listed below against the unit fitted to the vehicle, as these alternators are frequently identified by OE codes.

How To Replace
Replacement is straightforward for a competent mechanic with basic tools. Typical steps:
- Disconnect the negative terminal of the battery before starting work.
- Release tension on the accessory/serpentine belt and remove the belt from the alternator pulley.
- Disconnect electrical connectors and the positive battery feed from the alternator (mark connectors if needed).
- Unbolt the alternator mounting bolts and remove the unit from the bracket.
- Install the new alternator, tighten mounting bolts to the manufacturer’s specification, reconnect wiring and refit the belt with correct tension.
- Reconnect the battery, start the engine and verify charging system operation (charging voltage should typically be in the expected range when engine is idling and under load).
Installation Recommendations
Always Disconnect The Battery Before Work. Check And If Necessary Replace The Drive Belt And Tensioner When Installing A New Alternator. Inspect Electrical Connections For Corrosion And Clean Contact Surfaces. After Installation, Measure Charging Voltage With A Multimeter—normal charging is typically around 13.8–14.8 V depending on on-board regulators and conditions. If the vehicle has advanced stop/start or additional battery management, follow vehicle-specific restart/initialization procedures as required.
Why This Part Usually Fails
Common failure causes include worn brushes, voltage regulator faults, diode/rectifier failure, bearing wear, and contamination from oil or coolant leaks. Excessive heat, frequent short trips, heavy electrical loads or a slipping/old drive belt accelerate wear. In some cases, water ingress or prolonged exposure to road salts can cause premature electrical or bearing failure.
Durability And Service Interval
Alternator life depends on driving style and environment. Under normal conditions alternators commonly last well over 100,000 km, but high-mileage cars, frequent short journeys or electrical overload can reduce service life. If you notice dimming lights, battery warning lamp, unusual bearing noise or an undercharged battery, inspect the alternator and charging system promptly.
Notes For Purchasing
This unit is often located by OE/product numbers listed above. Use the product codes when searching to ensure compatibility. The alternator is intended as a direct replacement for the specified engine types and models; check the physical connector and mounting arrangement if in doubt.
