Car Air Conditioning: Six Tips for Car Air Conditioning Inspection in Autumn
Car air conditioners are hard work throughout the summer. In autumn, car enthusiasts should focus on taking care of it.
firstCheck whether there is enough refrigerant, which can be estimated by feeling the temperature difference between the inlet and outlet lines of the dryer, or by using a manifold pressure gauge.
SecondlyAlways clean dust and dirt from the air outlets and cab. This not only contributes to the appearance of the car, but is also beneficial to the health of the drivers and passengers.
thirdRegularly check whether the liquid level of the refrigerant in the air conditioning system is normal. There are several ways to check the fluid level, but the most common and easiest way

Car Air Conditioning: Six Tips for Car Air Conditioning Inspection in Autumn
Car air conditioners are hard work throughout the summer. In autumn, car enthusiasts should focus on taking care of it.
firstCheck whether there is enough refrigerant, which can be estimated by feeling the temperature difference between the inlet and outlet lines of the dryer, or by using a manifold pressure gauge.
SecondlyAlways clean dust and dirt from the air outlets and cab. This not only contributes to the appearance of the car, but is also beneficial to the health of the drivers and passengers.
thirdRegularly check whether the liquid level of the refrigerant in the air conditioning system is normal. There are several ways to check the fluid level, but the most common and easiest way is to check through the dryer peephole.
fourthcheck whether the compressor belt is in good condition. If the surface of the belt is in contact with the pulley groove and the side is bright, and there is a "squeaking" noise when starting the air conditioner, it means that the belt is seriously slipping and the belt and pulley should be replaced; if the belt is too loose, it should be adjusted, otherwise the air conditioning system may be prone to poor cooling.
fifthcheck the air conditioning system hoses and pipe joints for oil stains. If leakage is found, please consult maintenance personnel for solutions in a timely manner.
sixthWhen the car air conditioner is used for the first time after changing seasons, it is best to sterilize and deodorize the air conditioning system. This is because the air conditioning system will breed fungi and mold when it is "off" for a long time. It not only makes the air emit an unpleasant musty smell, but is also harmful to the health of the people in the car. You can go to a repair shop to do this work, or you can buy a special sterilization and deodorizing spray to handle it yourself.
Air conditioning filter needs to be cleaned and replaced
Routine cleaning of air conditioners can be done every six months. It is best to do some dusting and cleaning when the seasons change. When washing the car, you can remove the condenser and clean it with a high-pressure water gun. Because when driving at high speed, leaves and insects may be caught in the car. Simple cleaning will be more conducive to the heat dissipation of the car. It is also necessary to clean the air conditioning filter. But the cleaning method should be determined according to its material. If it is a filter, it can be removed and cleaned with water, which is simple and economical. If it is made of activated carbon, this method is not advisable. In addition, the air conditioner's blower must also be dusted.
Engine: listen to the sound to determine the working status
When maintaining your car, you must not only look, but also listen carefully. Because from the sound, the car will convey its health status to the owner. In autumn, car owners can choose to listen to the "voice" of their cars in a relatively quiet place. For example, you can choose to pay attention to determine whether there are abnormal sounds in the vehicle's pulleys, engine and other components when the car is cold started. If there is a sound similar to metal knocking, it is necessary to conduct a careful inspection.
Car tires: Pay attention to check tire wear
When maintaining cars between seasons, car enthusiasts need to pay attention to tire testing and maintenance. Summer tires are more likely to crack due to high temperature friction and wear. During driving, cracks will also increase. Therefore, when performing maintenance during the change of seasons in autumn, car owners should pay special attention to checking whether there are cracks in the tires, and carefully detect surface damage to see if there is any abnormal wear, etc. to ensure driving safety. At this time, riders can use tire indicator marks (wear limit position) or depth gauges, vernier calipers and other methods to detect. According to reports, the limit size of tire groove depth markings is 1.6mm. It is important to remind, especially new car owners, to pay attention to the markings on the tire limit positions before driving. Once the tires are worn to the limit, they must be replaced in time.
Car engine oil changes seasonally and the oil concentration should be adjusted appropriately
In addition to checking the tires, changing the engine oil is an important part of vehicle maintenance. Due to the use of the vehicle, the impact of the environment and the changes of some materials over time, regular inspections and timely detection are necessary to avoid greater damage or accidents. When performing seasonal maintenance, special attention should be paid to the concentration of the car's engine oil. Usually, car enthusiasts need to consider the change of seasons when choosing engine oil. Because the viscosity of oil changes with temperature, the viscosity becomes higher in winter and lower in summer. Therefore, in hotter areas and seasons, try to choose engine oil with a slightly higher oil viscosity. When the temperature changes and the weather is cold, lower viscosity engine oil can be used.
Interior: The interior needs to be thoroughly sterilized and cleaned when the weather is cold in autumn.
When the seasons change, it is necessary to fully disinfect the interior of your car. In summer, the carpets and floor coverings, seat cushions and other interiors in the carriage, as well as some dead corners in the carriage, may be filled with dust and are prone to breed various bacteria. Once the weather gets colder and the car windows are closed, the air in the car begins to become turbid, and odors and bacteria will pose a hazard to human health. Therefore, during the change of seasons, you can perform a thorough interior sterilization and cleaning of your car, such as steam sauna, photocatalyst disinfection, etc., to ensure the health and comfort of the riding environment.
