What items do Corolla need to do for the first maintenance?

Hello, Carola is doing maintenance for the first time. Major maintenance usually takes kilometers as the main reference standard. For most private cars, it is reasonable to do it once every three years or 60 thousand kilometers. If you only drive 30 thousand kilometers in three years, you don't need to carry out large-scale maintenance. You can extend it for a while and then go to the 4s shop for maintenance. Usually, if you use the car many times, you can drive more than 60 thousand kilometers in three years, but this is definitely not a private car, and you can also choose to maintain it in advance. Cars are inseparable from maintenance. If it is not maintained, it will not only hurt the car, but also have potential safety hazards when using the car. For example, if you don't mind car tires, you are not sure whether they are there, so you are more likely to have punk accidents while driving. In addition, before driving at high speed, in order to avoid the safety caused by too high or too low tire pressure, car owners must also develop the habit of checking tire pressure. Because the replacement cycle of auto parts is different, each maintenance project may be different. Shorter maintenance time depends on the effective time or mileage of the oil and oil filter used, less maintenance and other maintenance items. Generally, the frequency of alternate maintenance depends on the manufacturer's location. Many manufacturers have a large maintenance interval every 20,000 kilometers. That is, major maintenance. What are the specific items of car maintenance? Usually, the oil and oil filter need to be replaced every maintenance. In the harsh environment of high temperature and high pressure of the engine, the oil will be greatly shortened, thus greatly reducing the performance, and the engine can not be protected for a long time. The oil filter element can prevent impurities from being mixed into the oil to cause oxidation, and prevent adhesives and sludge from blocking the oil circuit. The function of the air filter is to prevent dust and particles from being inhaled by the engine when intake air is taken. If the filter is not cleaned for a long time, dust will be sucked into the engine, resulting in abnormal wear of the cylinder wall. During the overhaul, the air filter needs to be replaced.

I hope I can help you!
