【Car owner's family car knowledge]Car air conditioners are frequently used in winter and summer, but many car owners do not remember the cleaning and maintenance of car air conditioners in time when the seasons change, which will adversely affect the use of air conditioners in the next year. However, in order to prevent car owners from forgetting regular maintenance when the season changes, car owners and friends can usually accumulate maintenance experience by themselves, and clean the air conditioner of their own car from time to time. It is best to replace and clean the air conditioner filter element once a month.
Under normal working conditions, the service life of an original air conditioner filter element is 30,000 kilometers or one year. If the air conditioner filter element is cleaned frequently, the service life of the air conditioner filter element can be extended. If the vehicle has been used for more than 20,000 kilometers, it is recommended to replace the air filter. Of course, it is not necessary for maintenance experts in 4S shops to do it yourself, mainly because the location of the air filter is difficult to find, and secondly, some models may need to remove a few more screws during the disassembly and installation process.
Do-it-yourself replacement: about 50 yuan
The location of the air-conditioning filter element is different for different models. There are two main types: 1. Some air-conditioning filter elements are under the front windshield of the car and are covered by a diversion trough. When replacing the filter element, first lift the engine cover and remove it. Fix the clip of the water tank, remove the water tank, and you can see the air conditioner filter element. 2. The air-conditioning filter element of most family cars is located in the storage box under the windshield in front of the passenger seat. It is very convenient to disassemble. Just remove the storage box and you will see the air-conditioning filter element inside.
Replacement Tips:
When you go to the 4S store to replace the air filter, it will rarely help you clean the sponge grid. The sponge grid is the layer of oily sponge under the paper grid, which is the first pass for the air conditioner to clean the air. Because cleaning is troublesome, 4S shops rarely do this process. But when replacing the air conditioner filter element by DIY, you can completely clean it yourself: after washing it with ordinary washing powder, blot it dry, drip oil on it and knead it by hand, and then use toilet paper to absorb excess oil and put it back.
Internal cycle cleaning of car air conditioner
The internal circulation air inlet of the air conditioner is in the storage compartment of the passenger. There is a spray that can lock the nozzle. Open it, lock it, and put it on the passenger floor in a continuous automatic spray state. The nozzle is facing the direction of the storage box, turn on the air conditioner and internal circulation, and the air volume is the largest, which can be completed in about five minutes, and then open the door for ventilation.
External circulation cleaning of automobile air conditioner
Open the lower cover of the passenger's wiper, take out the air conditioner filter, turn on the air conditioner, and use the external circulation to maximize the air volume. Spray the air inlet continuously with spray. Install the new filter element and the cleaning process is complete.
Precautions when cleaning
During the cleaning process, open the door or window to keep the car circulating for a period of time. If the evaporator is partially blocked, you can add a large amount of air conditioner cleaning spray. After each spray, let it stand for 10 minutes to dissolve the dirt. Repeated cleaning several times. If it is seriously blocked, please fold it down and use a brush to brush repeatedly.
The cleaning process of the entire car air conditioner is relatively simple. By cleaning it yourself, the effect is similar to that of car beauty shop cleaning, and it can save some money.
