Notes
- Please clean the cooling system pipe of your car before installing the compressor, if the cooling system pipe is stuck, it will cause the compressor to burn out due to the large pressure. Flushing is the best way to get old oil and any solid contaminants when replacing any of the parts of an automotive air conditioner system. When a part fails, for example, your A/C compressor, debris and possibly metal shavings may be present in the system.
- We strongly recommend professional installation. Please contact us if you have any questions.
- Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before you place the order.

Automotive Air Conditioning Compressor Disassembly and Assembling Steps
1. Preparation
Before you start to disassemble the automobile air conditioning compressor, you need to do the following preparatory work.
1. Make sure the car has been parked and completely turned off.
2. The vehicle should be in a flat and safe environment, avoiding operation on slopes or unstable ground.
3. Wear acid and alkali-resistant gloves and goggles for protection.
2.Disassemble the air conditioning compressor
2.1 Compressor location determination
Before removing the air conditioning compressor, its location needs to be determined. Typically, the air conditioning compressor is located at the front of the engine compartment, and its exact location can be found through the technical manual provided by the vehicle manufacturer or online resources.
2.2 Discharging the refrigerant
Before removing the air conditioning compressor, the refrigerant in it must be drained. This is very important as refrigerants can be harmful to the environment and illegal. The following are the steps for discharging the refrigerant.
1. Open the hood of the vehicle.
2. Locate the refrigerant charging and discharging ports on the air conditioning compressor.
3. Use a refrigerant recovery machine to pump out the refrigerant and store it. Be sure to follow local regulations to ensure proper handling of the refrigerant.
2.3 Removing the connecting piping
After discharging the refrigerant, it is necessary to remove the connection pipes on the air conditioning compressor. These pipes are usually bolted or clamped to the compressor. The following are the steps for removing the connecting pipes.
1. Loosen the bolts or pliers on the connecting pipes with the appropriate tools.
2. Carefully separate the connecting pipe from the compressor. It may be necessary to shake the connection pipes gently to loosen them.
2.4 Removing the electrical connections
After removing the connecting pipes, it is necessary to remove the electrical connections on the compressor. These electrical connections are usually secured to the compressor by plugs or screws. The following are the steps for removing the electrical connections.
1. Locate the electrical connections on the compressor.
2. If there is a plug connection, carefully unplug it from the compressor.
3. If there is a screw connection, use the appropriate tool to loosen the screw and remove the wire.
2.5 Removing the compressor
After completing the above steps, the entire air conditioning compressor can now be removed. The following are the steps for removing the compressor.
1. Remove the bolts or screws holding the compressor in place using a wrench or wrench glove device.
2. Carefully remove the compressor from its mounting position.
3.Installation of a new air-conditioning compressor
3.1 Preparation for installing a new compressor
Before installing a new air conditioning compressor, some parts need to be prepared. The following are the steps of preparation.
1. Clean the joints of the connecting pipes and make sure that their surfaces are clean and dust-free.
2. Prepare the new compressor and make sure it fits your vehicle model and cooling system.
3. Prepare new washers, bolts, or screws to fix the new compressor.
3.2 Installing the air conditioning compressor
The following are the steps for installing a new air conditioning compressor.
1. Carefully place the new compressor in its mounting position.
2. Use new bolts or screws and place washers in the necessary positions before installation.
3. Tighten the compressor bolts or screws using a wrench or wrench-glove device.
