Description
Air Conditioning Compressor Bracket To Engine Block For Citroën C1, Peugeot 107, Toyota Aygo.
Durable replacement bracket engineered to secure the air conditioning compressor to the engine block on compact city cars from Citroën, Peugeot and Toyota. This bracket restores correct compressor alignment, reduces belt wear and vibration, and helps prevent premature accessory failure. Suitable for professional workshops and experienced DIY mechanics who maintain or repair small petrol engines. Frequently searched under original part numbers, installation-ready and compatible with common OE references for these models.
Typical Application And Benefits: The bracket provides a rigid mount between the compressor and engine block, keeping the compressor pulley correctly aligned with the drive belt. Correct alignment reduces noise, improves belt life and prevents excessive load on compressor bearings. Replacing a damaged or corroded bracket is a cost-effective repair that avoids more expensive compressor or belt-damage consequences.
Removal And Replacement Overview: Start by relieving drive belt tension and supporting the compressor to avoid stress on hoses and lines. Remove the drive belt, disconnect any interfering brackets or components and unbolt the compressor bracket from the engine block. Reinstall the new bracket, secure all fasteners to manufacturer torque recommendations, refit the drive belt and verify pulley alignment. If refrigerant lines must be disconnected during the job, follow applicable safety and environmental regulations for refrigerant recovery and reconnection.
Signs Of Failure: Common symptoms include rattling or knocking noises from the compressor area, accelerated or uneven belt wear, visible corrosion or cracks on the bracket, and misaligned compressor pulley. In severe cases the bracket can fracture, causing sudden compressor or belt failure.
