Alternator Bracket 1.6 HDi Euro5 For Citroën And Peugeot Vehicles
Overview
This alternator bracket is designed for 1.6 HDi Euro5 diesel engines used in a range of Citroën and Peugeot models. Manufactured to match OE mounting points and geometry, the bracket secures the alternator in the correct position to maintain belt alignment and reliable charging system performance. Ideal for professional workshops and DIY mechanics who search by part number (9684613880, 5706N9).
Application
Compatible With Common Models (fitment should be checked against vehicle engine code and year):
- Citroën Berlingo B9
- Citroën C4 II
- Citroën C4 Picasso
- Citroën C5 X7
- Peugeot 3008 I
- Peugeot 308
- Peugeot Partner Tepee
Function And Common Failure Modes
The alternator bracket holds the alternator firmly to the cylinder head or engine block, ensuring correct pulley alignment with the accessory drive belt. A secure bracket prevents belt misalignment, abnormal wear, and vibrations that can damage the alternator bearing or electrical connections.
Common Reasons For Failure:
- Corrosion and metal fatigue from road salt and moisture leading to cracks or breaks.
- Impact or mechanical shock following engine/transmission work or accidents.
- Excessive vibration caused by worn engine mounts accelerating stress on the bracket.
- Stripped threads or failed mounting bolts due to improper installation or overtightening.
How To Replace
High-level Replacement Steps (for experienced mechanics and competent DIYers):
- Park the vehicle on a level surface, engage the parking brake and disconnect the negative battery terminal.
- Remove any engine covers or intake components blocking access to the alternator and bracket.
- Release belt tension and remove the drive belt from the alternator pulley.
- Disconnect alternator electrical connectors and remove alternator mounting bolts to allow alternator to be moved or supported.
- Unbolt and remove the damaged alternator bracket. Inspect adjoining surfaces and mounting threads for damage.
- Fit the new bracket, using new bolts where recommended. Refit the alternator, reconnect electricals and reinstall the drive belt; set correct belt tension.
- Reconnect the battery, start the engine and check charging system voltage and that there are no unusual noises or belt misalignment.
Always Follow Manufacturer Torque Specifications And Service Procedures. If Mounting Threads Are Damaged, Repair Or Replace As Needed Before Reassembly.
Installation Recommendations
- Disconnect The Battery Before Work To Prevent Short Circuits And Protect Electronic Components.
- Use New Fasteners If The Old Bolts Show Corrosion Or Thread Wear; Apply Threadlocker Where Specified By The Manufacturer.
- Check Alternator Pulley Alignment And Accessory Belt Condition; Replace The Belt And Tensioner If They Show Wear.
- Inspect Engine Mounts And Nearby Components For Wear That Could Transfer Excess Vibration To The New Bracket.
- Verify Charging Voltage After Installation (Typically Around 13.8–14.6 V With Engine Running).
