Fitment And Application
This bracket is intended primarily for the small 1.0-litre city car family sharing the same platform (Citroën C1 / Peugeot 107 / Toyota Aygo). It is the part that secures the AC compressor to the engine block and is replaced when the original bracket is bent, cracked, corroded or when performing compressor removal/replacement or major service work in the accessory drive area.
Replacement Procedure
- Park Vehicle Safely: Work on a level surface, apply parking brake and support vehicle securely.
- Safety Precautions: If A/C refrigerant work is required, have refrigerant recovered by certified personnel—do not open refrigerant lines without proper equipment.
- Disconnect Battery: Isolate negative battery terminal before beginning disassembly to prevent electrical hazards.
- Relieve Drive Belt Tension: Release tensioner and remove accessory belt to access compressor and bracket.
- Support Compressor: Secure the AC compressor to prevent strain on hoses; avoid disconnecting refrigerant pipes unless necessary and performed by qualified staff.
- Remove Fasteners: Unbolt the compressor from the bracket if required, then remove the bracket-to-engine bolts and remove the bracket.
- Fit New Bracket: Position the new bracket, install bolts and tighten to manufacturer torque specifications (refer to factory manual for exact values).
- Reassemble: Refit compressor, reinstall drive belt, restore belt tension and reconnect battery. Verify belt alignment and check for unusual noise during engine run-up.
Installation Recommendations
- Use correct grade replacement bolts and new washers if original fasteners show corrosion or stretch.
- Always follow the vehicle manufacturer’s torque settings and tightening sequence to avoid distortion.
- Inspect surrounding components (belt condition, tensioner, compressor mount points) and replace as needed while access is available.
Why This Part Commonly Fails
Bracket failure is usually caused by a combination of age-related corrosion, metal fatigue from repeated vibration, impact damage (e.g., front-end contact) or stress from a seized or improperly functioning compressor. Symptoms include rattling or knocking noises from the accessory drive area, visible cracks or deformation on the bracket, misaligned or slipping drive belt, and accelerated wear of belt-driven components.
When To Replace
There is no fixed service interval for the compressor bracket. Replace the bracket if it shows visible damage, if the compressor has to be removed, or if there are symptoms of misalignment or abnormal vibration. Replacing the bracket during AC compressor service or when replacing accessory belts is common practice to ensure long-term reliability.
Order by OE number (88431-0H010 / 6453RL) for quickest identification and compatibility with Citroën C1, Peugeot 107 and Toyota Aygo models.
