Description
Compressor bracket for Citroën and Peugeot vehicles with 1.1i, 1.4i and 1.6i engines.
Product Overview
This replacement compressor bracket (OE references 9656881780 / 6453JT) is designed to restore the correct mounting and alignment of the air conditioning compressor on a range of Citroën and Peugeot models. Built to factory geometry, the bracket eliminates play that causes belt misalignment, premature belt wear and unwanted vibration. Ideal for professional workshops and experienced DIY mechanics looking for a direct-fit spare part listed under the original part numbers.
Function And Application
The compressor bracket secures the A/C compressor to the engine block or a dedicated mount and maintains correct belt alignment with the crankshaft pulley and other accessory pulleys. A solid, undamaged bracket prevents compressor movement under load, reduces noise, and protects the compressor bearings and drive belt. It is commonly replaced when the original bracket is bent, cracked or its mounting points are corroded.
Compatibility And Fitment
Typical applications include (but are not limited to): Citroën C3, Citroën C3 Pluriel, Citroën C4, Peugeot 206, Peugeot 206+, Peugeot 207 and Peugeot 307. Compatibility depends on engine and production year; the bracket is associated with vehicles using 1.1i, 1.4i and 1.6i engine families. This part is commonly searched and ordered by part numbers 9656881780 and 6453JT—match the part number with your vehicle’s documentation to ensure correct fitment.
Replacement Procedure
- Safety First: Disconnect the negative battery terminal before starting work.
- Relieve accessory belt tension and remove the drive belt from the compressor pulley.
- Support the A/C compressor to avoid stress on refrigerant lines (use a strap or support bracket). Do not disconnect refrigerant lines unless the system has been evacuated by a certified workshop.
- Remove compressor mounting bolts and unfasten the old bracket from the engine block.
- Fit the new bracket, align components, and torque all fasteners to the manufacturer’s specifications (refer to the vehicle service manual).
- Reinstall the compressor mounting bolts, refit the drive belt and set belt tension as specified.
- Reconnect the battery, start the engine and check for correct belt tracking and absence of unusual noises. Verify A/C operation if the system was not opened.

Installation Recommendations
Always follow the vehicle manufacturer’s repair manual for correct torque settings and tightening sequence. Replace any damaged or corroded bolts and consider replacing the drive belt if it shows signs of wear. If work requires opening the air conditioning system, have refrigerant recovered and recharged by a certified technician. Use proper hand and eye protection and ensure the engine is cool before starting work.
Most Common Reasons For Failure
Compressor brackets typically fail due to metal fatigue, corrosion (especially in regions with road salt), mechanical impact from minor collisions, or as a secondary effect of excessive engine vibration caused by worn engine mounts. Symptoms of a failing bracket include belt misalignment, squealing or chirping noises from the accessory drive, visible cracking or deformation of the bracket, and premature belt or pulley wear. Replace the bracket at the first sign of damage to avoid further damage to the compressor or drive system.
