How often should refrigerant be added to a car?

Refrigerant in a car should typically be added every 2 to 3 years, and its primary function is to lower the temperature of the air inside the vehicle. Here are methods to determine if your car needs refrigerant: 1. Turn on the air conditioning for a while—if it quickly reaches the set temperature, it indicates normal operation; otherwise, refrigerant may need to be added. 2. Use a thermometer to measure the temperature difference between the air intake and outlet of the indoor unit—if the difference is less than approximately 8 degrees Celsius, refrigerant may need to be added. The steps for adding refrigerant to a car are as follows: 1. Prepare the necessary tools and materials, such as a car refrigerant recovery and filling machine and refrigerant. 2. Connect the hoses of the refrigerant recovery and filling machine to the high and low-pressure pipes of the car's air conditioning system. 3. Perform a vacuum process on the car's air conditioning system. 4. Set the filling capacity, time, and type on the refrigerant recovery and filling machine. 5. The refrigerant recovery and filling machine will then automatically begin adding the refrigerant.

How to Solve Parking Assist System Malfunction?

Parking assist system malfunctions require inspection and repair at an authorized car 4S dealership. The functions of the parking assist system are: 1. The system measures the parking space and calculates the required distance to park between two vehicles; 2.
