Direct-fit alternator mount for 1.4 HDi 16V engines used on Citroën and Peugeot models. Supplied under OEM references 9646424380 and 5706G3, this bracket secures the alternator to the engine block and restores correct belt alignment and tension. Ideal for professional workshops and DIY mechanics who need a reliable replacement part that matches factory geometry and mounting points.

This alternator mount is designed to deliver a solid, vibration-resistant connection between the alternator and engine. Replacing a worn or damaged bracket eliminates excessive alternator movement, reduces belt wear, and prevents premature failure of the alternator bearings and drive components. The part is compatible with common applications of the 1.4 HDi 16V family and is frequently searched by OEM part number, making it easy to find when ordering.

Installation Recommendations

Always Disconnect The Battery Before Starting Work. Support The Alternator Or Engine As Required To Remove Load From The Bracket. Typical Replacement Steps:

• Loosen and remove the drive belt (release the belt tensioner where fitted).
• Support the alternator to prevent it dropping when unbolted.
• Remove the mounting bolts securing the alternator bracket to the engine block.
• Inspect mating surfaces and fasteners; clean threads and check for damage.
• Fit the new bracket, align the alternator and hand-tighten bolts before torquing to manufacturer specifications.
• Reinstall the belt, set correct tension, reconnect the battery and verify charging system operation.

Use New Fasteners If Original Bolts Are Corroded Or Damaged. Follow Manufacturer Torque Specifications And Procedures To Avoid Thread Stripping Or Misalignment.

Why This Part Fails Most Often

• Corrosion And Rust: Exposure To Moisture And Road Salt Can Cause Metal Fatigue And Localized Weakening.
• Vibration And Fatigue Cracks: Continuous Engine And Accessory Vibration Leads To Crack Initiation Over Years Of Service.
• Seized Or Damaged Fasteners: Frozen Bolts Can Shear During Removal Or Prevent Proper Clamping Force.
• Impact Or Collision Damage: Front-End Impacts And Engine Bay Hits Can Bend Or Break The Bracket.
• Indirect Causes: Worn Engine Mounts Or Misaligned Accessories Increase Load On The Bracket And Accelerate Wear.

Fitment And Notes

Fits 1.4 HDi 16V Engines Commonly Found On Citroën C3 And Peugeot 1007. Frequently Identified By OEM Numbers 9646424380 And 5706G3 — Search By These Codes For Fast Identification. No Specific Replacement Interval; Inspect During Timing Belt/Service Intervals Or If You Notice Belt Misalignment, Unusual Noise, Or Alternator Movement.

Recommendation

For Best Results, Replace Any Corroded Or Damaged Fasteners And Check Associated Components (Belt, Tensioner, Alternator Bearings) At The Same Time. If You Are Unsure About Access Or Correct Torque Values, Seek Professional Installation To Ensure Long-Term Reliability.
