Description
Alternator Bracket for Citroën and Peugeot Vehicles With 1.6 e-HDI Start-Stop Engines
Product Overview
This alternator bracket is designed for Citroën and Peugeot models equipped with the 1.6 e-HDI Start-Stop engine. The sturdy mounting bracket secures the alternator to the engine block, maintaining correct alignment and belt tension for reliable charging performance. Ideal for professional workshops and DIY mechanics who require an exact-fit replacement part specified by part numbers 9674030280 and 5706P8.
Why This Part Matters
The alternator bracket is a structural component: it positions the alternator relative to the crankshaft pulley and tensioner. A damaged or bent bracket can cause belt misalignment, accelerated belt wear, charging faults, abnormal noise, or premature alternator failure. Replacing a compromised bracket restores correct alignment, noise-free operation, and consistent charging of the battery and electrical systems—especially critical for vehicles with Start-Stop systems.
Applications And Fitment
Fits common Citroën and Peugeot models equipped with the 1.6 e-HDI Start-Stop engine. Typical applications include:
- Citroën C4
- Citroën C4 Picasso
- Peugeot 308
- Peugeot 3008 I
- Peugeot 5008 I
Searchable by OEM/Product Codes: 9674030280, 5706P8. These numbers are commonly used by mechanics when sourcing the correct replacement part.
Installation Recommendations
Follow a methodical installation process to ensure safe and correct fitment:
- Disconnect the battery before starting any work to avoid electrical shorts.
- Loosen and remove the accessory drive belt, noting belt routing and tensioner position.
- Support the alternator and remove its mounting bolts, then remove the old bracket from the engine block.
- Compare the new bracket with the old part for matching mounting points and hole alignment.
- Install the new bracket and hand-start bolts first to ensure correct alignment; tighten to the manufacturer’s torque settings where available.
- Refit the alternator, set proper belt tension, reconnect electrical connectors, and reconnect the battery.
- After installation, verify charging system operation and listen for abnormal noises during an engine run.
Use appropriate threadlocker or anti-seize according to workshop practice and the vehicle manufacturer’s recommendations. If torque values are not available, consult the service manual for exact figures.
Most Common Failure Causes
- Corrosion And Rust: Long-term exposure to moisture and road salt can weaken the bracket, causing cracks or breakage at mounting points.
- Mechanical Damage: Impacts from road debris or collision repair can bend or crack the bracket, upsetting alternator alignment.
- Vibration And Fatigue: Repeated engine vibration, worn engine mounts, or excessive belt tension can lead to metal fatigue and eventual failure.
- Stripped Or Damaged Threads: Over-tightening or cross-threading during previous repairs can damage bolt threads, preventing secure mounting.

Additional Notes
This bracket is not a routine wear item but should be inspected whenever the charging system or belt drive is serviced. Replace immediately if you observe cracks, deformation, stripped threads, or if the bracket no longer secures the alternator with correct alignment. Professional installation is recommended for precise alignment and correct torqueing to avoid premature wear of belt-driven components.
