Description
Air conditioning compressor bracket to the engine block for Citroën C1, Peugeot 107, Toyota Aygo.
Product Overview
This heavy-duty A/C compressor bracket secures the air conditioning compressor to the engine block on small city cars from the Citroën/Peugeot/Toyota family. Designed for a precise fit, the bracket restores correct compressor alignment and belt path, ensuring reliable belt drive performance and reducing vibration transfer to the compressor housing.
Who Should Use This Part
Ideal for professional auto technicians and competent DIYers working on Citroën C1, Peugeot 107 or Toyota Aygo models. Often searched and ordered by OE product number, this bracket is a common replacement part in workshops performing A/C, accessory drive or engine-mount repairs.
Function And Typical Failure Modes
Function: The bracket provides a rigid mounting point between the A/C compressor and the engine block, maintaining correct pulley alignment and allowing the drive belt to run smoothly.
Why It Fails: The most common causes of bracket failure are metal fatigue and cracks due to long-term vibration, corrosion in regions with road salt, impact damage from collisions, or stripped/overstressed mounting bolts. Failure symptoms include squealing or slipping belts, visible misalignment of the compressor pulley, unusual vibration from the front of the engine, or oil/bolt thread damage around the mounting area.
Installation Recommendations
- Inspect Compressor And Belt: Before fitting the new bracket, check the compressor housing, pulley, and drive belt for wear or damage. Replace the belt and any damaged tensioners as necessary.
- Use Correct Fasteners: Always use original specification bolts or equivalent quality replacements. Replace any corroded or stretched bolts and washers.
- Tightening Procedure: Tighten fasteners to the manufacturer’s torque settings. If torque values are not available, consult service documentation for the specific engine variant.
- Alignment Check: After installation, spin the accessory belt by hand to ensure pulleys run true and there is no edge contact or misalignment.
- Corrosion Protection: Clean mating surfaces and treat exposed metal with suitable anti-corrosion product if required to extend service life.
- Safety: Support the compressor while removing or fitting the bracket to avoid stress on refrigerant hoses. Avoid disconnecting A/C lines unless qualified and equipped to recover refrigerant.
