Product Overview
This DENSO compressor is a belt-driven unit designed to compress and circulate refrigerant in the vehicle air conditioning system. It includes the clutch assembly and electrical connector as found on the donor vehicle. The compressor was removed from a vehicle with 94,000 km and is suitable for replacing failed units in compatible Citroën, Peugeot and related models. It restores cold-air performance when installed correctly and paired with a clean, correctly serviced A/C system.

Function And Symptoms
The compressor is the heart of the A/C system: it compresses low-pressure refrigerant vapour into high-pressure vapour and drives circulation through the condenser, expansion device and evaporator. Typical failure symptoms include loss of cooling, A/C clutch not engaging, abnormal noise from the compressor area, visible oil or refrigerant leaks and seized compressor causing belt slippage or breakage.
Common Causes Of Failure
- Contamination in the system (metal debris, moisture) that damages internal components
- Lubrication loss due to refrigerant/oil leak, causing bearing or piston wear
- Electrical clutch coil failure or connector corrosion
- Overheating from low refrigerant charge or blocked condenser
- Age and normal wear, especially in vehicles with high mileage or poor maintenance
Replacement And Installation
- Recover refrigerant using certified A/C recovery equipment in accordance with local regulations.
- Disconnect the battery and follow vehicle manufacturer safety procedures.
- Remove accessory belt and disconnect electrical connector from the compressor clutch.
- Undo mounting bolts and remove the compressor. Inspect system for debris and contamination.
- Replace O-rings on high- and low-pressure lines with correct sizes lubricated with the specified oil.
- If contamination is present, flush the system or replace affected components (condenser, receiver/drier or accumulator, expansion valve) to prevent rapid re-failure.
- Install the replacement compressor, torque fasteners to manufacturer specification, evacuate the system with a vacuum pump and recharge with the correct refrigerant type and oil volume as specified by the vehicle manufacturer.
- Check for leaks, verify correct clutch engagement, and confirm cooling performance during a road or bench test.
Installation Recommendations
- Always use proper refrigerant recovery and charging equipment. Never vent refrigerant to atmosphere.
- Replace receiver/drier or accumulator when replacing the compressor if the system has been opened or contaminated.
- Use the manufacturer’s specified refrigerant oil type and quantity (typically PAG for modern systems) and follow torque settings from the repair manual.
- Perform a full system vacuum and leak test before charging. Run the system to circulate oil and verify operation.
- Professional installation is recommended for correct evacuation, charging and leak checking, but experienced DIY mechanics with appropriate tools can perform the job safely.
Most Common Reason For Failure
The single most common cause of compressor failure is contamination and lubrication loss in the refrigerant circuit. Debris from a failing component or moisture in the system accelerates internal wear and can lock the compressor, making replacement necessary. Preventive maintenance and prompt repair of small leaks significantly reduce the risk of compressor damage.
