Rubber tube aging. The rubber pipe in the engine compartment will age over a long period of time, which is easy to happen in cars with long cars. Once aging, gasoline may leak into the engine compartment. The air conditioning system will let gasoline smell into the car.
Solution:
Once the rubber tube is aged, it needs to be replaced in time!
2. Reason:
There is a leak at the gasoline pipe joint. There may be a leak at the interface of the gasoline pipe, causing the smell of gasoline to enter the car through the air conditioning system. If the owner finds that there is gasoline smell in the car, he should check the gasoline pipeline interface.
Solution:
When the engine compartment cover is opened, it is easy to judge whether the gasoline pipe joint leaks oil, because a layer of sludge will appear on the surface after a period of oil leakage. If the joint of the gasoline pipe is found to be leaking, tighten or repair the joint.

Maintenance of automobile air conditioner;
1, air conditioning comprehensive inspection
When using the air conditioner for the first time in summer, you should first check the air conditioning system, such as checking whether the refrigerant and air conditioning filter are too dirty and whether there are foreign objects in the radiator passing through the liquid storage tank.
2, air conditioning cleaning
Some novices always wait until the air conditioner doesn't work before thinking of cleaning the air conditioner, which is wrong. Air-conditioning filter should be replaced regularly, because there are more dust in Beijing and Liu Xufei in spring, which will stick to the filter and easily breed bacteria and make the air conditioner have a musty smell, so it is best to replace it once a year after the spring. In addition, the condenser should be cleaned regularly, and the water tank should be removed and thoroughly cleaned.
Don't turn off the air conditioner after parking.
After the owner arrives at the destination, he usually leaves directly after closing the air conditioning door. Different from the autumn and winter seasons, in the hot summer, the huge temperature difference between the inside and outside of the car will lead to mildew in the air conditioning system, which in turn will breed mold.
Therefore, the owner should turn off the air conditioner and turn on the natural wind a few minutes before arriving at the destination, so as to raise the temperature in the air conditioning pipeline and eliminate the temperature difference with the outside, thus keeping the air conditioning system relatively dry and avoiding mold propagation.
4. Turn up the air volume regularly.
Some car owners rarely or never turn on the air conditioner to high air volume because they don't like the noise when the air conditioner is turned on to high gear. But the air conditioner will suck in a lot of dust when it is used. It is a simple way to keep the air conditioner clean by blowing strong wind regularly to blow out the floating dust on the inner surface of the air duct. In addition, special air duct cleaning solution should be used for sterilization, cleaning and deodorization.
