Description
Alternator bracket for CITROËN and PEUGEOT vehicles with 1.6 HDI engine.
This alternator bracket is a direct-fit mounting component designed for Citroën and Peugeot models equipped with the 1.6 HDi diesel engine. It secures the alternator to the engine block, maintains correct belt alignment and tensioner geometry, and ensures reliable charging system operation. The part is commonly searched by OE references 9658199380 and 5706L1, so include these codes when looking up fitment or ordering.

Compatibility And Fitment Notes
Intended for use on Citroën and Peugeot models fitted with the 1.6 HDi engine family. Always check the vehicle model year and engine code when comparing part numbers. The OE references 9658199380 and 5706L1 are the most common identifiers used by workshops and spare-parts databases.
Replacement Procedure
- Park the vehicle on a level surface, set the handbrake and isolate the battery.
- Loosen the accessory drive belt by releasing the tensioner and remove the belt from the alternator pulley.
- Disconnect the alternator electrical connectors and, if required, remove the alternator to gain access to the bracket.
- Support the alternator and remove the mounting bolts securing the bracket to the cylinder head/block.
- Fit the new bracket in position, start bolts by hand, then tighten to the manufacturer’s torque specifications.
- Reinstall the alternator, reconnect electrical connections, refit the drive belt and set the correct belt tension.
- Reconnect the battery and verify charging system operation at idle and under load.
Installation Recommendations
- Always isolate the battery before starting work and follow manufacturer safety procedures.
- Use proper tools to release and set belt tension; avoid forcing or bending the alternator housing.
- Replace any corroded or damaged fasteners and apply threadlocker where recommended by the vehicle manufacturer.
- Tighten mounting bolts to the maker’s torque values; if unavailable, consult repair manuals or official service documentation.
- After installation, inspect belt alignment and run the engine to check for abnormal noises or vibration.
Why This Part Most Often Fails
Alternator brackets typically fail due to corrosion and metal fatigue after years of exposure to road salt and moisture, or because of mechanical stress from engine movement when other mounts or silentblocks are worn. Broken or seized mounting bolts, damage from improper belt tensioning, and impact from road debris can also lead to failure. Failure symptoms include misaligned drive belt, belt squeal, alternator movement, charging faults or visible cracks in the bracket.
Practical Tips For Workshops And DIY Mechanics
- When replacing the bracket, inspect adjacent components: alternator bearings, belt condition, tensioner, and engine mounts (silentblocks).
- Keep the OE product codes 9658199380 and 5706L1 in job notes to simplify future ordering and parts lookup.
- If threads in the cylinder head are damaged, address the repair before fitting the new bracket to avoid repeat failures.
