Description
Air Conditioning Compressor Bracket For Citroën And Peugeot Vehicles
This replacement air conditioning compressor bracket is designed for a range of Citroën and Peugeot models with HDi diesel engines. It secures the A/C compressor to the engine, keeping correct alignment with the accessory drive and ensuring consistent belt tension. The bracket is a frequently searched spare part by OE numbers (9641715380, 9646719580) and cross-references (6453NS, 5606P9), which makes ordering and identification fast for professional workshops and DIY mechanics.
Overview
The compressor bracket transfers loads between the engine block and the A/C compressor. A robust bracket prevents misalignment-related belt wear, noise, and premature compressor damage. This part is suitable for vehicles equipped with 1.6 HDi, 2.0 HDi and 2.2 HDi engines where the original bracket design is used. Fitment includes many popular Citroën and Peugeot models, commonly replaced during A/C or accessory-drive repairs.

Installation Recommendation
Before starting work, disconnect the negative battery terminal and follow the vehicle manufacturer’s safety procedures. Because the A/C system contains pressurised refrigerant, have the refrigerant recovered and the system made safe by a qualified technician before detaching the compressor. Typical installation steps:
- Recover refrigerant from the A/C system (by a certified workshop).
- Remove the accessory drive belt and any obstructing components to access the compressor and bracket.
- Support the compressor to prevent strain on hoses, then unbolt and remove the old bracket.
- Fit the new bracket, install fasteners and tighten to the manufacturer’s torque specifications.
- Reinstall the compressor, belt and other components, then evacuate and recharge the A/C system to specification.
Why The Part Most Commonly Fails
Compressor brackets typically fail due to corrosion, metal fatigue or impact damage. Constant vibration from the engine, especially in higher-mileage diesel vehicles, can cause cracks or fractured mounting points. Stripped or broken threads from previous incorrect installation are another frequent cause. When a bracket becomes distorted, compressor alignment is lost, which accelerates belt wear and may overload the compressor bearings.
Practical Tips
- Inspect surrounding fasteners and accessory mounts when replacing the bracket; damaged bolts or worn bushings should be renewed.
- Check pulley alignment after installation to avoid premature belt failure.
- Use new sealing washers or locking compounds where specified by the manufacturer.
- Record the part numbers (9641715380 / 9646719580 / 6453NS / 5606P9) — mechanics and DIYers often search by these codes when sourcing spares.
Benefits
Replacing a worn or damaged compressor bracket restores correct alignment and drive-belt tension, reduces noise and vibration, and helps protect the A/C compressor and accessory-drive components from premature failure. Suitable for both professional workshops and experienced DIY mechanics who follow safe handling and A/C service procedures.
