Installation recommendations
Generally/typically for air conditioning compressor replacement, the exact procedure may vary depending on the specific model and design of the car. With the air conditioning system, it is necessary to work professionally, taking into account the refrigerant and the cleanliness of the entire system.
1) Before assembly
- Compare the new and original part by manufacturer, marking, body shape, attachment, pulley and connection points.
- Check for damage to the pulley, connector, threads or connection surfaces.
- Check the condition of the belt and surrounding drive components.
- Check the system for signs of dirt, metal particles, or refrigerant leaks.
2) Necessary tools and materials
- Common workshop tools
- Preparations for dismantling covers and fasteners
- Equipment for professional handling of the air conditioning system
- Cleaning agents suitable for the assembly of air conditioning parts
- Suitable protective equipment
3) Step-by-step assembly procedure
- Secure the car against movement and prepare your work space.
- Professionally ensure that the air conditioning system is safely shut down prior to disassembly according to normal service practice.
- Disconnect related parts that prevent access to the compressor.
- Release the accessory drive so that the belt can be removed from the compressor pulley.
- Disconnect the electrical connections and the air conditioner piping, keeping the open inlets clean and protected from dirt.
- Remove the original compressor from the mount.
- Before fitting the used part, re-compare all seating and connection points with the old part.
- Mount the compressor in place and seat evenly into the mount without force.
- Connect piping and electrical connector so as not to damage sealing surfaces or contacts.
- Reassemble the belt and other removed parts.
- After mechanical assembly, carry out a professional commissioning of the air conditioning system according to the normal procedure for the given type of system.
- Verify that the compressor runs smoothly, without excessive noise and without obvious vibrations.
-
4) Post-assembly checks and test drive / function verification
- Check the tightness of the joints and the overall condition of the connection.
- Verify the correct operation of the pulley and the smooth running of the system.
- Watch for unusual sounds, vibrations or odors.
- During the test run, verify that the air conditioner responds normally and cools without interruptions.
5) The most common assembly mistakes + how to avoid them
- Exchanging a part based on an inaccurate designation – always compare all numbers and designs.
- Installation in a dirty system – check the circuit for dirt or signs of internal damage before installation.
- Damage to connection points – tighten the connections sensitively and without crossing.
- Incorrect seat of the belt – after installation, check for correct routing and seating.
- Underestimate the post-assembly inspection – always perform a functional verification and watch for possible leaks or non-standard sounds.
Reasons why the part is damaged
- Lack of lubrication in the system which can lead to seizing or excessive wear of internal compressor parts.
- Contamination of the air conditioning circuit with metal particles or other impurities.
- Leaks in the system, due to which the system does not work in an optimal mode.
- Excessive load or poor condition of the accessory drive, such as a worn or misaligned belt.
- Long-term shutdown of the air conditioner without regular operation, which can contribute to the deterioration of the condition of seals and moving parts.
- Incompetent assembly or starting the system without adequate control of downstream components.
