Air conditioner compressor Sanden SD6V12 1449 9655191580

Description

Air conditioner compressor for Citroen PEUGEOT cars
It is from a Citroen Xsara Picasso 1.6 16V
Mileage of the car 84 thousand km

Part description

Used Sanden SD6V12 air conditioning compressor (type 1449) designed for Citroën/Peugeot cars. This is a part from a Citroën Xsara Picasso 1.6 16V with a stated mileage of 84,000 km. The air conditioner is a key part of the air conditioner – it ensures the compression of the refrigerant and the correct functioning of the cooling in the cabin.

When choosing, we recommend that you mainly follow the product numbers listed below, as they often match across multiple variants.

Installation recommendations

Generally/typically for air conditioning compressor replacement the procedure below applies. The exact steps may vary according to the specific model and design of the air conditioning circuit.

1) Before assembly (checks of the used part, what to compare with the old part)

• Compare the codes (9655191580, 9800822280, 6453QE) and compressor type Sanden SD6V12 with the old part.
• Check for damage to the attachment points, connector/electrical part and connection points of the circuit.
• Verify that the compressor rotates freely (without significant stuttering) and there is no obvious mechanical damage.
• If the original system shows signs of seizing or contamination (metal chips in the circuit), address the cause first – replacing the compressor alone is usually not enough.

2) Necessary tools and materials (in general, without specific extra parts)

• Common hand tools (ratchet, sockets, wrenches, screwdrivers)
• Suitable equipment for working with air conditioning (service station / extraction and filling of refrigerant in the service)
• Cleaning agents for degreasing contact surfaces (according to practice)
• Protective equipment (gloves, glasses)

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and allow the engine to cool.
2. Have the refrigerant expertly extracted from the air conditioning system (working with refrigerant requires equipment and procedures).
3. Disconnect the compressor electrical connection (connector).
4. Release the drive/accessories so that the compressor can be removed (typically the belt and access elements depending on the car model).
5. Disconnect the A/C lines from the compressor and protect the open ends from dirt.
6. Dismantle the fixing screws and remove the old compressor.
7. Clean the mating surfaces and check the condition of the circuit connection.
8. Install the used compressor, seat it correctly in the brackets and tighten the fasteners according to the manufacturer’s instructions.
9. Connect the A/C pipe and electrical connector.
10. Return the removed parts and restore the accessory drive.
11. Perform vacuum and filling of the air conditioner at the service station and a basic leak check.
12. Check the operation of the air conditioner with the engine running (compressor switching on, stable operation, no unusual noises).

• 4) Post-assembly checks and test drive/function verification

  • Check for leaks at circuit connections.
  • Listen to the operation of the compressor – whistling, knocking or fluctuating operation is a warning signal.
  • Verify that the air conditioner cools and the system works stably even during extended operation.

  5) The most common assembly mistakes + how to avoid them

  • Assembly without cleaning/addressing circuit contamination → can quickly destroy an otherwise good compressor.
  • Contamination in the open circuit (uncovered pipes) → always protect the line ends against dust.
  • Omission of code match check → compare part numbers and designs before assembly.
  • Underestimation of tightness after filling → always check leaks and system behavior after commissioning.

  Reasons why the part is damaged

  • Insufficient lubrication in the air conditioning system (typically related to leaks or improper system service).
  • Circuit contamination (dirt, metal particles after the original compressor seized).
  • Long-term operation with leakage and gradual degradation of function.
  • Overload due to problems in the circuit (e.g. restricted flow, clogging – in general).
  • Mechanical damage during unprofessional disassembly/assembly or in the event of an accident.
