Description
Air conditioning compressor bracket for Citroën and Peugeot vehicles with a 1.6 16V NFU engine
Part description
Used Citroën Peugeot air conditioning compressor bracket is used to securely mount the air conditioning compressor and keep it correctly positioned in relation to the belt drive. It is a suitable solution when replacing a cracked, deformed, or otherwise damaged original bracket, provided it matches the specific vehicle configuration.
When selecting a bracket, refer primarily to the codes 9657137480 and 6453KG and compare its design with the original part. A correctly selected bracket allows the compressor to be securely mounted without modifying the mounting points.

Installation recommendations
The following procedure applies generally to this type of part. The exact access, extent of disassembly, and tightening sequence depend on the specific vehicle model and configuration. Follow the manufacturer’s service procedure. Have work on the refrigerant circuit performed by a specialist workshop with the appropriate equipment.
1) Before installation
- Compare the code, shape, hole spacing, mating surfaces, and mounting design with the old bracket.
- Inspect the used part, especially around the mounting holes and stressed transitions. Check for cracks, deformation, or damaged threads, if threads are part of the bracket.
- Check the condition of the fasteners, opposing mating surfaces, and compressor mounting points.
- Determine the cause of the original bracket’s damage to prevent the problem from recurring after replacement.
2) Tools and materials required
- A standard set of wrenches and sockets suitable for the fasteners.
- A torque wrench and the manufacturer’s service specifications for the specific vehicle.
- Suitable equipment for releasing the belt drive tension, depending on its design.
- A secure support or suitable means of suspending the compressor.
- Cleaning products, a brush, cloths, and protective equipment.
- If working underneath the vehicle, suitable lifting and support equipment.
3) Step-by-step installation procedure
- Park the vehicle on a level surface, secure it against movement, and allow the engine to cool. Prevent the engine from being started unintentionally.
- Following the vehicle’s service procedure, disconnect the battery and make the work area accessible. If you raise the vehicle, support it securely.
- Before disassembly, record the belt routing and the positions of the parts being removed, for example by taking a photo.
- Following the procedure specified for the particular configuration, release the belt tension and remove the belt as far as necessary to carry out the work.
- Securely support or suspend the compressor before releasing its mounting. Its weight must not be borne by the air conditioning hoses or pipes.
- Release the compressor and carefully move it aside only as far as the connected lines allow. If you cannot continue without disconnecting the circuit, stop work and arrange for a professional to recover the refrigerant. Do not release refrigerant into the environment.
- Remove the original bracket fasteners and take off the bracket. Note their original positions and any differences in design.
- Clean the mating surfaces and inspect the opposing mounting points. Repair damaged threads or deformed surfaces before installing the replacement part.
- Position the replacement bracket without forcing it and initially fit the fasteners by hand. The bracket must seat correctly; it must not be pulled into position by tightening the bolts.
- Secure the bracket and compressor in the order and to the torque specified in the manufacturer’s service procedure. Check that the compressor is seated without stress and that the air conditioning lines are not under strain.
- Check the condition of the belt and related drive components. Route the belt correctly and restore its tension using the specified procedure.
- Reinstall the removed components, remove the compressor support and tools. Restore the electrical supply following the manufacturer’s procedure.
4) Post-installation checks and test drive / function check
- Before starting the engine, check that all fasteners are in place, the belt is seated correctly, and there is adequate clearance around moving components.
- After starting the engine, observe the drive from a safe distance. Do not touch the moving belt or pulleys.
- Check that the air conditioning works and listen for knocking, squealing, or unusual vibrations. If the engine runs irregularly, switch it off and rectify the cause.
- If everything is in order, take a short test drive and then, with the engine switched off, inspect the mounting and surrounding lines again.
5) Most common installation errors + how to avoid them
- Selecting a part based only on the vehicle model: also compare the codes and the bracket’s overall design.
- Tightening over dirt or with incorrect seating: clean the surfaces and check that the part is seated without stress before tightening.
- Leaving the compressor hanging from the hoses: always support or suspend it separately.
- Using incorrect bolts or tightening by guesswork: use the specified fasteners and follow the manufacturer’s service specifications.
- Incorrect belt routing: record the belt path before removal and check that it is seated correctly after installation.
- Replacing the bracket without addressing the cause of the fault: also check the compressor, belt drive, and related mountings.
Reasons why the part may be damaged
Air conditioning compressor brackets are generally damaged by mechanical overloading, prolonged vibration, or incorrect installation. This does not describe the observed condition of this particular item.
- Loose fasteners cause the bracket to move and repeatedly stress the mounting holes.
- Incorrect tightening or installation under stress can damage the threads, mating surfaces, or the bracket itself.
- A fault in the compressor or belt drive can increase the load and vibration transmitted to the mounting.
- Impact or careless handling during repair can cause deformation or cracking.
- Prolonged cyclic stress can lead to fatigue cracks, especially if the mounting is already weakened.
