Description
Product Overview
The Sanden SD7C16 1300F air conditioning compressor, referenced by OE numbers 9656572480 and 6453RA, is designed for PSA Group vehicles (Citroen and Peugeot). This unit is a direct-fit solution commonly found on models such as Citroen C5 (example: 2006 2.0 16V) and a range of Peugeot 407 and 607 derivatives. Mechanics and experienced DIYers often search by the part numbers, so listing these codes ensures quick identification.
Key Benefits
- Direct-fit design for straightforward installation on compatible PSA vehicles.
- Reliable cooling performance when paired with the correct refrigerant and oil.
- Widely searchable by OE/product numbers (9656572480, 6453RA) for fast sourcing.
- Suitable for workshop replacement or professional DIY jobs.
Function And Common Failure Modes
The compressor pressurizes and circulates refrigerant through the air conditioning system, enabling heat exchange and cabin cooling. Common reasons for compressor failure include lubricant contamination, refrigerant leaks leading to insufficient lubrication, seized bearings from wear or contamination, clutch failure, and electrical faults in the clutch coil or connector. Regular system maintenance and prompt repair of leaks extend compressor life.
Replacement And Installation Notes
Replacing the compressor should be performed by a qualified technician or an experienced DIYer with appropriate equipment. Typical steps:
- Verify vehicle-specific refrigerant type and oil specification before starting.
- Recover and store refrigerant using certified recovery equipment.
- Disconnect the battery, remove the drive belt, and disconnect the electrical connector to the compressor clutch.
- Unscrew compressor mounting bolts and separate refrigerant lines (cap and seal lines immediately to avoid contamination).
- Replace any O-rings on the lines with new ones lubricated with the correct PAG oil; install the new compressor and torque mounting bolts to manufacturer specs.
- Evacuate the system with a vacuum pump to remove moisture and confirm system tightness.
- Charge the system with the correct refrigerant type and the recommended oil volume. Test for leaks and verify correct operation and pressures.
Note: For PSA vehicles of this era the system typically uses R134a and the manufacturer-specified PAG oil. Always confirm the exact refrigerant and oil type from the vehicle’s service data before refilling.
Service Life And Maintenance
Compressor lifespan depends on operating conditions, maintenance, and system integrity. With a leak-free system and proper lubrication, compressors commonly last many years, but contamination, neglected leaks, or electrical issues reduce service life. When replacing the compressor, inspect the entire A/C circuit (condenser, dryer/receiver, expansion valve/orifice tube) and replace the receiver/drier or accumulator to protect the new unit.
Compatibility And Identification
Often identified by OE/product numbers, which are widely used in parts catalogs and diagnostic searches. Common fitments include:
- Citroen C5 (example application: 2006 2.0 16V)
- Peugeot 407
- Peugeot 607
- Other PSA models using the SD7C16 compressor variant
Always confirm fitment using the vehicle identification number (VIN) or by cross-referencing the OE numbers 9656572480 and 6453RA.
