2. Tire maintenance: check the tire pressure in summer. Because of the high temperature, the tire cannot be inflated too much. Autumn is different, because the temperature is relatively low, it is necessary to add air pressure to the tires and hit the specified range. At the same time, you should also check whether the tires have obvious trauma, scratches and so on. In autumn and winter, rubber is brittle, which not only reduces the friction coefficient, but also makes it easier to leak air and puncture tires.
3. Check the engine compartment: the contents include engine oil, steering oil, brake oil and antifreeze.
4. Check the brake system: pay attention to whether the brake fluid is sufficient and the quality is deteriorated. If necessary, it should be supplemented or replaced in time. At the same time, pay attention to whether the braking is weakened or deviated, the stepping force of the brake pedal and the position of the wheel locking point during braking, and clean up the pipeline part of the whole braking system if necessary.
5. The maintenance of the ignition system is related to whether the vehicle can be started, so carefully check whether the plug is rusted. Once it rusts, it should be treated with a professional cleaning agent. In addition, the maintenance of spark plugs should not be taken lightly.
6. Maintenance of charging system: After rain and high temperature, it is important to check whether the generator belt is aging or cracked. If this does not happen, remember to check the tightness of the belt. If the belt is too loose, it will cause the belt to scream and wear prematurely; If the belt is too tight, it will cause eccentric wear of the generator bearing.
7. Chassis Derusting The maintenance of automobile chassis in autumn focuses on rust removal and tire inspection. On the one hand, the metal materials of the chassis are easy to rust after exposure to the sun and rain, which affects the driving safety. Therefore, it is necessary to rust the chassis and check whether there are scratches and screws falling off on the chassis.
8. Replace antifreeze: The weather turns cold in autumn. Once the cold air arrives, the temperature drops suddenly, which is likely to affect the normal work of the automobile cooling system. It is suggested that the tap water in the water tank should be drained in time and antifreeze should be used instead. If your car has been using antifreeze, you don't need to replace it immediately. Need to be reminded that the replacement cycle of antifreeze is 2 years. Don't forget to clean the engine cooling system before replacing antifreeze.
9. Check whether there are sundries at the air inlet or grille and electronic fan. Compressed air can be used to blow away the dust. After the engine is cooled, use a water gun to wash the above parts from the inside out.
10. battery maintenance the electrode wiring of the battery is a place that is prone to problems this season, so pay attention to maintenance. In the process of inspection, if green oxide is found at the electrode wiring, it should be removed in time. 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.
1 1. Maintenance of heating pipes and fans. When the weather turns cold in autumn, frost will appear when the temperature is low. In this season, you should 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, otherwise it will bring unsafe factors to driving.
12. Maintenance of air conditioners. I believe that many car owners and friends will conduct a comprehensive inspection and maintenance of air conditioners when they enter summer, so that air conditioners can operate normally in hot summer. After a summer's overload operation, we should have an inspection and maintenance before entering autumn. There is a lot of rain in summer, and vehicles often take some wading roads, so the lower part of air-conditioning condenser will inevitably be polluted by sediment. Over time, a lot of silt and dust were deposited, which seriously affected the service life of air conditioners. So it is necessary to check and maintain the air conditioner again in this season. In addition, the vehicle water tank is also easily polluted by sediment, which deserves everyone's attention. Once sediment deposits are found in these areas, they should be removed immediately.
13. Cleaning the water tank condensation network is hot and rainy in summer, which not only increases the frequency of air conditioning, but also accumulates many impurities with moisture, such as cotton wool and leaves. This will have an impact on two aspects: first, it is easy to breed bacteria; Second, it affects the heat dissipation function of water tank and condenser. To eliminate these effects, it is recommended to go to the auto repair shop to find a professional to clean it. In order to thoroughly remove the bacteria and odor in the car, it is best to replace the air conditioning filter in the car at the end of summer to increase the coolness of the air conditioner and improve the ride comfort.
14. Indoor cleaning: After a rainy and hot summer, a large number of bacteria grew in hidden places such as carpets and floor coverings. With the arrival of autumn, the windows are no longer opened frequently, and the air inside the car begins to become turbid. Odor and bacteria will do harm to people's health, so it is best to sterilize and clean the car thoroughly in this summer and autumn.
