Description
Overview
High-quality Valeo CL8+ alternator designed for Citroën and Peugeot petrol engines from 1.0 to 1.6 litres, including 1.4 16V and 1.6 16V variants. Delivers 14 V system voltage and a charging output of 80 A, featuring a 4-point mounting and an integrated voltage regulator for reliable electrical system performance.
Function
The alternator converts mechanical energy from the engine into electrical power to charge the battery and supply the vehicle’s electrical systems while the engine is running. The integrated regulator ensures steady voltage output to protect sensitive electronics and maintain battery health.
Typical Failure Modes And Service Life
Alternators commonly fail due to worn brushes, bearing wear, voltage regulator faults, internal diode failures, belt slip or contamination from oil and coolant. Service life varies with use and conditions, typically between 80,000–150,000 miles (approx. 5–10 years) depending on vehicle duty cycle and maintenance.
Installation And Replacement Notes
- Disconnect the negative battery terminal before any work to avoid short circuits.
- Loosen and remove the drive belt from the alternator pulley.
- Disconnect electrical connectors and the main charging cable from the alternator.
- Remove the alternator by unbolting the 4-point mounting brackets. Support the unit during removal to avoid damage to wiring.
- Fit the replacement unit, reconnect electrical connections, tension the drive belt to the manufacturer specification, and reconnect the battery.
Note: Always check belt condition and battery state when replacing an alternator. Use correct belt routing and specified belt tension. If unsure, consult the vehicle repair manual for torque and alignment specifications.
