1. The air conditioner must be cleaned and maintained:
In summer, someone laughed and said, "Life is given by air conditioning." In summer, the utilization rate of air conditioning is extremely high, which is more in line with operation. Moreover, there are more rainy days in summer. We often drive back to some muddy wading sections. This kind of pavement can easily make a lot of sediment stand on the lower part of the air conditioner condenser. Long-term scouring will rust the condenser, thus shortening the service life of the air conditioner. After autumn, when there is little rain, you should maintain the air conditioner once, and pay attention to the maintenance of the warm air pipe and fan. It's getting cold in autumn, and the heating equipment will be used soon. And when the temperature is low, we should also pay attention to the appearance of frost. Pay special attention to whether the defrosting outlet under the windshield is normal and whether the heat is sufficient. Problems should be solved in time.
2. The door glass guide groove should also be cleaned:
This year, Beijing caught a heavy rain. Continuous rain makes a lot of dust and acid and alkali substances flow into the guide groove along the glass. At this time, the glass lifter will be very weak, and the glass will rise and fall slowly or there will be some abnormal noise rubbing against the glass. The reason for this phenomenon is that a lot of dust accumulates in the glass guide groove, so the glass guide groove should be cleaned. Car owners can spray some water into the guide groove with a watering can, or use a professional cleaner, such as some big brands of glass guide groove reducer, to clean the guide groove, and then lift the glass up and down several times, and the lifting speed and smoothness will be good!
3. If the tread pattern is too shallow, replace the tire in time.
In summer, the temperature is high. In order to prevent the tire pressure from being too high and bursting, it is necessary to check the tire pressure frequently, while in autumn, on the contrary, it is necessary to pay attention to the tire pressure within the specified range. At the same time, you should also check whether there are scratches on the tires, because rubber tends to harden in autumn and winter, and tires are prone to air leakage or puncture.
In addition, it often rains in early autumn, and cars mainly pay attention to whether the tire tread is clear enough. It is easy to cause danger if the tire tread is not clear enough in rainy days. Too shallow tread tends to reduce the friction between the tire and the ground, and the braking distance will also become longer. If the tread depth of the tire is less than1.6mm, please replace it with a new tire. Tyres that have been repaired should be replaced with rear wheels, and tyres that have been repaired more than three times should be replaced.
4. Remove the oxide from the battery
The electrode joint of the battery is a place prone to problems in summer and autumn, so attention should be paid to maintenance. During inspection, if green oxide is found at the electrode wiring, remember to wash it with boiling water. If these green oxides are not removed, the generator will generate insufficient power and the battery will be in a state of power loss. In severe cases, the battery will be scrapped in advance or the car will not start. After washing with boiling water, dry the water with compressed air, and then spray special protective agent to prevent the oxide layer from appearing again.
5. Beautiful appearance and clean inside.
During the transition period of summer and autumn, the maintenance of vehicle appearance and interior is worthy of attention. This may be more useful for friends in the south. There is a lot of dew in autumn morning, and the surface of cars is easy to get wet, while the weather in Beijing is dry. If there are obvious scratches on the surface of the car, it should be painted in time to avoid corrosion of the scratched parts due to moisture. In addition, due to the corrosion of rain and acid in summer and the direct sunlight in summer, the automobile paint surface will inevitably be oxidized. When changing seasons, it is best to give the car surface a beauty maintenance from cleaning and polishing to waxing, glazing or coating.
6. Check and maintain the spark plug.
The ignition system is related to whether the vehicle can be started. In autumn, cars mainly check these parts carefully, especially some plugs, to see if they are rusty. Once rusted, they should use professional cleaners to deal with it. In the selection and use of cleaning agents, we should also choose the maintenance products of regular automobile beauty maintenance shops to achieve the best results, and the maintenance of spark plugs is equally important. Once there is a problem, it will cause the vehicle to shake or stop.
7. Brake system maintenance
The brake system is mainly about the inspection of brake pads and brake oil. The inspection of brake pads is relatively simple, so I don't want to introduce it more. Brake oil should be mainly introduced, because it is easy for some water to penetrate into the brake system in summer, which leads to the softening of automobile brakes. Therefore, when the brakes become soft or other conditions occur, the brake system should be checked in time. Always check whether the brake is weakened or deviated, whether the pedal force of the brake pedal has changed, and clean the pipeline of the whole brake system if necessary.
8. Engine compartment maintenance
Always check the engine oil, brake oil and antifreeze in the engine compartment in autumn to see whether the engine oil is sufficient, deteriorated or not, and whether it is time to replace it. This oil is like the blood of a car. In the replacement cycle, it must be replaced to ensure smooth oil circulation. Some car owners like to use water instead of antifreeze in summer. On the surface, there is no problem with this practice, but the problem is that once the temperature drops suddenly, it is likely to affect the normal work of the automobile cooling system and even freeze.
