Clean the air conditioning pipe (key)
Because of the large temperature difference during operation, the air supply pipeline of air conditioning system is in a humid state for a long time, which will produce a large number of molds and bacteria for a long time, which is also the source of air conditioning odor.
Operating steps:
1. Remove the air conditioning filter and open the window;
2. Start the engine to start the external circulation mode of the air conditioner, turn on the AC key and adjust it to the maximum wind speed;
3. Spray air conditioner deodorant 10-20 seconds from the external circulation air inlet (the external circulation air inlet is generally under the wiper);
4. Close the window, switch to the internal circulation mode, turn on the AC key, and adjust to the maximum wind speed;
5. Spray the air conditioner deodorizer 10-20 seconds from the internal circulation air inlet (the internal circulation air inlet is generally near the main and auxiliary driving side gears); 6. Turn to the internal circulation warm air mode, turn on the maximum wind power, close the car doors and windows for 10- 15 minutes, open the car doors and windows and continue to run for 5- 10 minutes until there is no residual smell of cleaning agent.
Daily maintenance of the battery and the solutions that can't be started.
Working in a hot and humid environment for a long time, the anode and cathode of the battery are easy to oxidize at the turn of summer and autumn, which makes it difficult or even impossible to start the vehicle. It is found that there is green oxide in the click sound, which needs to be cleaned up in time. Open the engine compartment for inspection every three months.
You can buy a special antirust protective agent (usually tens of dollars) and spray it on the corresponding parts to prevent oxide regeneration; And if the battery can't start because of the serious shortage of electricity, it's best to keep a "power-saving treasure" in the car for a long time (usually you can buy it for two or three hundred yuan), which can really save the emergency at a critical moment.
Maintenance of tires
Tire is the foot of a car, and its good condition is directly related to the comfort of riding, even the personal safety of the people inside the car.
Every time you use the car, you should turn around the car body to check whether the tires are leaking. If there is obvious deflation, you should use a "portable pump" (both in 80 yuan and 300 yuan) as soon as possible to reach the rated tire pressure, otherwise driving with low tire pressure for a long time will lead to the risk of puncture; If the car is used frequently and the tires have been running for 30,000 kilometers or more than three or four years, it is also necessary to check whether the tires (sidewalls and tread patterns) have aging phenomena such as cracks, and replace them as soon as possible if found.
Spraying "tire glaze/brightener" after each car wash (generally only 20-30 yuan bottle is needed, and four wheels can be used for five or six times) can not only delay the appearance of cracking and aging, but also make the tires as bright and black as new cars, killing two birds with one stone.
