Alternator Bracket 1.6 HDi 16V For Citroën Peugeot Vehicles
Reliable alternator bracket engineered for 1.6 HDi 16V engines in Citroën and Peugeot cars. This mount secures the alternator to the engine block and preserves correct alignment and belt routing. The part is commonly searched by product numbers 9658199180 and 5706L3, making it easy for professional mechanics and DIYers to identify the correct replacement quickly.
This bracket is built to withstand engine vibrations and the loads transferred from the accessory drive. Proper alternator mounting prevents premature bearing wear, charging issues, and belt misalignment. Suitable for use during alternator replacement, timing of accessory drive components, or when correcting engine mounting alignment after collision or maintenance.
Function And Typical Symptoms
The alternator bracket holds the alternator in a fixed position relative to the engine, ensuring the drive belt maintains correct tension and pulleys remain aligned. When the bracket is damaged or worn, common symptoms include:
- Unusual belt noise or squealing.
- Visible wobble or misalignment of the alternator pulley.
- Intermittent charging system faults or battery warning lights.
- Excessive alternator bearing wear leading to grinding or whining noises.
Installation Recommendations
- Disconnect The Negative Battery Terminal Before Starting Work To Avoid Short Circuits.
- Relieve Belt Tension And Remove The Drive Belt To Access The Alternator And Bracket Safely.
- Support The Alternator While Removing The Mounting Bolts To Prevent Damage To Wiring Or The Alternator Body.
- Inspect Adjacent Components—Belt, Tensioner, Pulleys And Fasteners—and Replace Any Worn Parts During Reassembly.
- Clean Mating Surfaces, Fit The New Bracket, And Tighten Bolts To Manufacturer Specifications (Refer To Service Manual For Torque Values).
- After Installation, Check Belt Alignment And Tension, Start The Engine And Inspect For Noise Or Vibration.
- Use New Fasteners If Original Bolts Are Corroded Or Stretched; Apply Appropriate Thread Locker Where Specified.
