Air conditioning compressor Sanden SD7C16 1309f 9651911480

Descrizione

Air conditioning compressor for CITROEN and PEUGEOT vehicles SANDEN 1309f
Pulley – 119 [mm]
Refrigerant: R 134a

Part description

The used Sanden SD7C16 1309f air conditioning compressor for Citroën and Peugeot vehicles compresses and circulates refrigerant in the air conditioning circuit. Correct compressor operation is essential for effective cabin cooling. When replacing a faulty part, a used compressor is an affordable repair option while retaining the corresponding design.

To find the correct replacement, the 9651911480 designation, compressor type, and compatibility of the connections and mounting with the original part are particularly important. Matching the vehicle model alone is not sufficient, as air conditioning configurations may differ.

Installation recommendations

The following applies generally to this type of part: replacing an air conditioning compressor requires professional handling of the refrigerant, checking the cleanliness of the circuit, and correctly charging the system. The following procedure is general; the exact steps, access to the part, and service specifications depend on the specific vehicle model and configuration. Have the refrigerant recovered and the system charged by a qualified service provider with the appropriate equipment.

1) Before installation

• Compare the product numbers, type designation, mounting, refrigerant connections, electrical connection, and pulley configuration with the old compressor.
• Check the body of the used part, mounting points, connector, and pulley. The part must not have visible cracks, damaged connections, or signs of severe mechanical damage.
• Check that the openings are clean and the connections are protected from dirt and moisture. Dirt must not enter the circuit during installation.
• Determine the cause of the original fault. If the compressor has seized or metal particles are present, simply replacing the compressor is not sufficient; system contamination must also be addressed in accordance with the service procedure.
• Do not assume that the used compressor contains the correct amount of oil for your vehicle. The oil charge must be assessed in relation to the entire circuit.

2) Tools and materials required

• Standard mechanical tools, a torque wrench, and suitable tools for releasing the accessory drive.
• Service equipment for working with R 134a refrigerant, equipment for evacuating the system and checking for leaks.
• Clean caps for open connections, lint-free cloths, and protective equipment.
• Suitable seals for disconnected joints and compressor oil specified by the manufacturer of the particular system.
• Service documentation for the specific vehicle configuration.

3) Step-by-step installation procedure

1. Secure the vehicle against movement, switch off the engine, and prepare safe access in accordance with the service documentation.
2. Have any remaining refrigerant professionally recovered using service equipment. Do not disconnect the circuit while it is pressurized or release refrigerant into the atmosphere.
3. Before disconnecting electrical components, follow the vehicle manufacturer’s instructions for disconnecting the battery.
4. Remove only the components necessary for access. Note the belt routing and release the compressor drive according to the specified procedure.
5. Disconnect the electrical connection, if present, without pulling on the wires or damaging the connector clips.
6. Disconnect the refrigerant connections and immediately seal the open lines and openings with suitable clean caps.
7. Support the compressor, release its mountings, and remove it without putting strain on nearby lines.
8. Assess the condition of the circuit and any contamination. If the original compressor failed mechanically, carry out the specified cleaning and address any affected components before installing the replacement part.
9. Prepare the replacement compressor according to the service instructions, including verifying the correct oil charge. Check the mating surfaces and prepare the correct joint seals.
10. Install the compressor without applying strain, connect the lines with suitable seals, and tighten the joints according to the manufacturer’s specifications. Then reconnect the electrical connection and belt drive.
11. Check the belt routing and mountings, and ensure wiring and hoses are clear of moving parts. Reinstall the removed components and restore the power supply according to the manufacturer’s procedure.
12. Evacuate the system, check for leaks, and charge the air conditioning system with the specified amount of refrigerant for the particular vehicle. Start the system for the first time according to the service instructions.

4) Post-installation checks and function verification

• Check the disconnected joints for leaks and verify that the air conditioning system works correctly using service equipment.
• Monitor the operation of the belt and compressor. Unusual noises, vibrations, or erratic operation are grounds for stopping the test immediately.
• Check that the air conditioning system cools and that there are no signs of oil leaks at the connections.
• After a successful stationary check, verify operation during a short test drive, then recheck the joints and mountings.

5) Common installation errors and how to avoid them

• Replacing the part without addressing the original cause: check the circuit for leaks and contamination, and inspect the drive before installation.
• Incorrect oil charge: follow the documentation for the specific system, rather than estimating or relying only on the amount found in the used part.
• Dirt and moisture entering the system: leave connections open only as long as necessary and keep sealing them as you work.
• Damaging or reusing unsuitable seals: use suitable seals and assemble clean joints without forcing them.
• Starting the system before completing circuit servicing: do not operate the compressor without the specified preparation and correct charge.
• Incorrect belt seating or overtightened joints: check the drive routing and follow the vehicle manufacturer’s tightening specifications.

Reasons why the part may become damaged

The following causes may generally contribute to air conditioning compressor damage. This is not a description of any condition identified in this specific part.

• Insufficient lubrication due to refrigerant leakage or an incorrect amount or type of oil.
• Dirt and metal particles in the circuit, for example following a previous mechanical compressor failure.
• Moisture in the system due to the circuit being left open for an extended period or inadequate servicing.
• Excessive operating load caused by an incorrect charge or insufficient heat dissipation from the air conditioning system.
• Wear of the drive and pulley, incorrect belt routing, or vibration.
• Normal mechanical wear of internal components during long-term operation.
