Method and care for correct replacement of the walk-through ac electromagnetic valves
The proper operation of air-conditioning systems as a popular car is essential for the comfortable experience of drivers and passengers. The ac electromagnetic valve, on the other hand, plays a key control role in the ac system, and when it fails, the correct replacement is required. We will now look into the correct replacement of the walk-through ac electromagnetic valves and the issues that need attention during the replacement process。
The necessary tools, such as wrench, screwdriver, refrigerant recovery equipment, etc., should be prepared before replacement starts. At the same time, the vehicle was secured and the engine and power were shut down。
Next, we find the location of the avac electromagnetic valve. Usually, it is located in the vicinity of air-conditioning compressors and may need to be removed in order to be clearly visible。
Refrigerants in air-conditioning systems are then recovered using refrigerant recovery equipment to avoid environmental pollution from cooling leaks and to save costs。
When removing old electromagnetic valves, be careful not to damage surrounding parts and pipes. Use the appropriate tools and gradually follow the correct sequence of dismantling。
When the old electromagnetic valves are removed, the new electromagnetic valves are installed in their original position. During the installation process, it is necessary to ensure that the electromagnetic valves are installed in the right direction and that they are closely connected and free of any relaxation。
Once installed, the associated pipes and lines are reconnected and secured。
Here is a table comparing some of the key parameters of the old and new electromagnetic valves:

When installed, refrigerant recharge equipment is used to re-load appropriate refrigerants into air-conditioning systems。
Finally, start the engine, turn on the air conditioner, check whether the newly installed electromagnetic valves are working properly, and whether the air conditioner cooling is working well. At the same time, the presence of refrigerant leaks should be checked。
Throughout the replacement process, the following points require particular attention:
1. The operating environment shall be kept clean to avoid impurities entering the air conditioning system。
The seals used at the time of installation shall be of good quality to prevent leakage。
3. Operation in strict compliance with vehicle maintenance manuals and related standards。
4. If not familiar with the operation, it is recommended to seek the assistance of professional car maintenance staff。
In general, the correct replacement of the er requires a certain level of professional knowledge and skills, along with careful and disciplined operating procedures to ensure that the replacement air conditioning system works normally and steadily。
