How to add car refrigerant, how to add car refrigerant

In addition to the high-frequency use of air conditioners in summer, it is also a season in which air-conditioning problems erupt in large numbers. Generally speaking, for the problem that the air conditioner is not cooling, the refrigerant leakage accounts for most of the reasons. Then, after the leak is found out, the car refrigerant should be added like this?

How to add car refrigerant?

Notice:

Since the filling of refrigerant for car air conditioners requires special addition tools, and the requirements for refrigerant materials are relatively high, it is recommended that you go to the 4S shop to operate as much as possible, and if you do it yourself, it will be self-defeating.

The specific steps for adding refrigerant are as follows:

Ready to work:Before adding refrigerant, you need to prepare tools and materials such as automotive refrigerant recovery and filling machine, refrigerant (currently R-134a refrigerant is mostly used in automotive air conditioners, and different refrigerants must not be mixed).

Connecting pipeline:Connect the pipelines of the automobile refrigerant recovery and filling machine to the automobile air conditioning high and low pressure pipes (red to high pressure pipes, blue to low pressure pipes).

Vacuum:After the pipeline connection is correct and the self-check of the refrigerant recovery filling machine is completed, the car air conditioner can be vacuumed.

Add refrigerant:It is not until the end of vacuuming that the refrigerant can be added. According to the maximum capacity of the refrigerant marked by the vehicle air conditioner, set the filling capacity, time and type on the refrigerant recovery filling machine. After confirmation, the refrigerant recovery filling machine can automatically start adding refrigerant.
