Description
Alternator VALEO CL15 1.4 2.0 2.2 HDI Citroën Peugeot
Product information
Voltage [V] 14
Generator charging current [A] 150
Without freewheel pulley
Eyelet, connector
This Valeo CL15 alternator is a high-output charging unit designed for a range of Citroën and Peugeot HDi diesel engines (1.4 / 2.0 / 2.2). With a nominal output of 150 A at 14 V, it supplies electrical systems under heavy load and recharges the battery reliably during driving. The version listed is supplied without a freewheel (overrunning) pulley and uses an electrical lug plus a multi-pin connector for vehicle wiring.
Compatibility
Fits popular Stellantis models equipped with HDi engines. Typical vehicle applications include Citroën Berlingo, C2, C3, C3 Pluriel, Xsara, Xsara Picasso and Peugeot 1007, 206, 307, Partner. Often searched by product code 9646476280 and by Valeo CL15 designation.

Function and what it does
The alternator converts engine mechanical energy into electrical energy to power vehicle electronics and charge the battery. A steady 14 V charging output and up to 150 A peak current ensure stable operation of lighting, heating, injection systems and onboard electronics even under high electrical demand.
How to replace
Replacement should be carried out by a trained mechanic or experienced DIYer with basic tools. General steps:
- Disconnect the negative battery terminal to prevent short circuits.
- Release drive belt tension and remove the serpentine belt from the alternator pulley.
- Disconnect the electrical connector(s) and remove the battery eyelet from the stud.
- Unbolt the alternator mounting bolts and remove the alternator from its bracket.
- Install the new alternator in reverse order, check belt alignment and correct tension, reconnect electrical connections and battery.
- After installation, verify charging system voltage at idle (charging voltage should typically be around 13.8–14.6 V) and check for abnormal noises or belt slip.
Recommended installation notes
- Inspect and, if necessary, replace the drive belt and tensioner while replacing the alternator.
- Clean the electrical contacts and battery terminal before reconnection to ensure good conductivity.
- Do not run the engine with loose belt tension; recheck tension after a short test drive.
- Use appropriate lifting/support where access is limited and follow safety procedures when working near moving parts.
Why this part most commonly fails
Alternators typically fail due to mechanical wear and electrical stress. Common causes include worn bearings producing noise and rotor play, brush and slip ring wear reducing output, diode or rectifier failures causing charging faults, contamination from oil or coolant leaks, overheating from poor ventilation, and belt slip due to worn or loose belts. Excessive electrical load or battery faults can also accelerate alternator wear.
