2. Check the air conditioning pressure, replace the cooling medium
First check the pressure pipe and a low-pressure pipe were connected to the fluorine pressure detection table, the fluorine pressure gauge connection is completed, the vehicle ignition idling begins.
At this time the air conditioner switch is turned on, the air conditioning system starts running at maximum detection, detection of idle pressure should not exceed 300 high pressure, low pressure should not exceed 60 idle state.
After a few minutes idling, increase speed through to the oil pressure gauge to observe changes, and check the air conditioning compressor is functioning properly. Then remove the original system refrigerant, weight is generally between 250g-300g, received a gauge ready fluoride, generally two to three years is recommended car with a bottle or so, and some models can be added to two bottles.

3. Autumn and winter the right choice of a good oil.

When using external circulation, air inlet air from outside the vehicle, while the inner loop is recirculated-air use.
Inner loop can improve the air conditioning effect, but the prolonged use of loop will reduce the air quality inside the vehicle, you may feel dizzy. Under normal circumstances suggest that you use the outer loop to allow fresh air into the car, to improve air quality.

7 film to reduce the temperature
In autumn and winter, many owners will be affixed to their car solar film, film with UV resistant, improve the efficiency of air conditioning, heat and so on. In general, the market is selling solar film for ultraviolet blocking more than 98%,for women owners is undoubtedly the best choice.
