Tyre
Bus tires have "age", and even a brand new tire that has been stored for more than four years will age because the main material of the tire is rubber, and the characteristic of rubber is that it will age after prolonged use or storage. If an aging tire is used, it can easily affect the performance of the vehicle, and in severe cases, it can cause a tire blowout accident and endanger life. Identifying the production date of a tire is simple. You can find a string of 4-digit numbers near the wheel hub, with the first two digits representing the production week and the last two digits representing the production year. If the car mainly needs to change tires, it is important to carefully consider the production date when selecting. In addition, car owners should not blindly upgrade their tires, otherwise it may cause safety hazards. After determining the tire specifications, choose tires with the same pattern to ensure safe driving after upgrading.
Engine
Nowadays, many cars use low energy consumption and high power turbocharging technology. There are some areas that require special attention for this type of engine. Firstly, do not leave in the car. After the engine is started, especially in winter, it should be allowed to idle for a period of time to fully lubricate the bearings with lubricating oil before the turbocharger rotor runs at high speed. Secondly, do not immediately turn off the engine. After running the engine at high speed for a long time, it should idle for 3-5 minutes before turning off the engine.
Air-conditioning
The evaporator, fan, and other components of car air conditioners are in a closed and dark state for a long time, and the internal environment is hot and humid. After impurities, dust, bacteria, and viruses in the air enter the interior of the air conditioner, they adhere to the condensed water and block the evaporator and other components. Before using the air conditioner, it is recommended that car owners clean the air conditioning pipes and evaporation box. Currently, there are three methods for cleaning car air conditioners in the automotive service market: one method is disassembly and cleaning, which is very troublesome, time-consuming and labor-intensive, and can easily cause damage to the air conditioner during the disassembly and cleaning process; The second method is steam cleaning, which was relatively popular in the past two years. However, steam cleaning of air conditioning can easily cause damage to the circuit board in cars, so steam cleaning of car air conditioning is becoming increasingly rare nowadays; The third method is to clean with air conditioning cleaning solution.
Storage Battery
The lifespan of a battery is generally 2 to 3 years. If users install some previously unavailable electrical appliances, such as subwoofers, without authorization, it will cause excessive use of the battery. In the maintenance of automobiles, the maintenance of batteries is also very important. If bad usage habits are developed, it can shorten the service life of batteries or cause damage. A typical battery can last for 2 to 3 years.So, when using these electric devices, car owners should try not to overload the battery.
