Description
Air conditioning compressor for Citroën and Peugeot SANDEN 1309f.
Pulley – 119 mm
Refrigerant: R134a
Product Overview
This Sanden SD7C16 (1309f) air conditioning compressor is designed for a range of Citroën and Peugeot petrol and diesel models. It is a robust choice for professional garages and experienced DIY mechanics searching by OE numbers such as 9651911480 or cross references like 9825868180, 6453QL and 6453QN. The unit includes a 119 mm pulley and is compatible with R134a refrigerant systems. Replacing a failed compressor restores cooling performance and prevents secondary damage to other A/C components.

Function And Typical Lifespan
The compressor circulates refrigerant through the A/C system, compressing low-pressure gas into high-pressure gas so heat can be rejected by the condenser. Typical service life varies with usage and maintenance; many compressors last well over 100,000 km, but contaminant ingress, lubrication issues or clutch/bearing wear can shorten life significantly.
Installation Recommendations
- Recover Refrigerant With Proper Equipment: Always evacuate and recover refrigerant with certified A/C service equipment before removal.
- Replace Associated Components: Replace Receiver/Drier (or Accumulator) and expansion valve/orifice tube and O-rings when fitting a new compressor to avoid contamination and moisture-related failures.
- Flush System If Contaminated: If compressor failure produced debris, flush the system thoroughly or replace contaminated lines to prevent rapid re-failure.
- Use Correct Oil And Charge: Add the specified type and amount of PAG oil for the Sanden SD7C16 and charge the system with the correct quantity of R134a refrigerant per manufacturer specification.
- Vacuum And Leak Test: Evacuate the system with a vacuum pump for an appropriate time, perform a leak test, then charge and verify system pressures and temperatures.
- Belt And Tension Check: Inspect or replace the drive belt and tensioner; ensure pulley alignment is correct.
- General Safety: Disconnect the battery before beginning work on electrical connectors and follow safe working practices when handling refrigerant and pressurised systems.
Most Common Failure Reasons
- Contaminant Ingress: Metal debris from a failing compressor or contamination from other failed components causes internal scoring and seizure.
- Lack Of Lubrication: Insufficient oil or incorrect oil type accelerates wear of internal moving parts and bearings.
- Clutch Or Bearing Wear: Electrical clutch failures or worn bearings lead to noisy operation and eventual seizure.
- Moisture And Corrosion: Moisture in the system degrades lubricants and causes corrosion of internal components and valves.
- System Overpressure Or Blockage: Restricted flow (blocked expansion valve/filter) raises temperatures and stresses the compressor.
Why Choose This Compressor
Searching by OE number is common in workshops—this Sanden SD7C16 (1309f) unit corresponds to multiple OE references used across Citroën and Peugeot ranges. It offers direct-fit dimensions (119 mm pulley) for compatible models and supports R134a systems, making it a practical replacement part for restoring A/C performance quickly and reliably when installed with the recommended service procedures.
Note For Professionals
This listing includes OE and cross-reference numbers to help technicians and knowledgeable DIYers find the correct unit fast. Ensure the compressor codes match the vehicle’s original part to guarantee fitment and performance.
