The nine maintenance cycles of automobiles should be clear.

The nine maintenance cycles of automobiles should be clear.

As the saying goes, it is essential to maintain the vehicle on time if it is to be used well. However, there are many kinds of car maintenance projects and their prices are different. If you don't know the maintenance cycle and maintenance items of the car and do unnecessary maintenance, it is a waste of money! Now tell you, what is the maintenance cycle of those common maintenance items? Let you clearly maintain and spend less money!

0 1 engine oil

Changing the oil is the most common maintenance item for automobiles. Engine oil, also known as automobile engine lubricating oil, has four functions: cooling, lubricating, cleaning and sealing. Engine oil is divided into three categories: ordinary mineral oil, semi-synthetic engine oil and all-synthetic engine oil, and the oil change cycle of each category is also different.

Mineral engine oil, about 5000 kilometers or once every 6 months.

Semi-synthetic engine oil, about 7,500 kilometers or once every six months.

In synthetic engine oil, it should be replaced every 10000 km or 9- 12 months.

Note: the oil change cycle is based on mileage and time, whichever comes first. For example, vehicles using mineral oil need to be replaced even if they run less than 5000 kilometers within 6 months. If you often drive on dusty roads, congested roads, high temperature or cold areas, you need to replace them in advance.

02 Four filters

Four filters are commonly known as oil filter, air filter, fuel filter and air conditioner filter. As can be seen from the name, these four types of filter elements play a filtering role in all parts of the vehicle, and they are all consumable parts, which need to be replaced regularly.

Oil filter element, and replace the oil at the same time; The air filter element should be replaced every 10000 km, depending on the vehicle environment; Air-conditioning filter element, which is replaced every summer before air-conditioning is used; The fuel filter should be replaced every 20,000 kilometers, depending on the local oil quality.

03 antifreeze

Antifreeze liquid, the full name of antifreeze coolant, can make the engine of the vehicle still run normally in low temperature environment. In addition to anti-freezing, it also has anti-rust, anti-corrosion and anti-boiling functions. Because of the harsh working environment, the additives in antifreeze will fail after a long time, so the antifreeze should be replaced every two years or so.

04 transmission oil

Transmission oil mainly plays the role of lubrication and cleaning. Although some gearboxes now claim to be maintenance-free for life, in order to reduce gearbox wear and make gearbox shifting smoother, it is best to change gearbox oil every 3 years or about 60,000 kilometers.

05 brake oil

Brake system is directly related to vehicle safety, and brake oil is closely related to whether the brake system can be used normally. Brake oil that is not replaced for a long time will deteriorate, which will affect the braking effect of the vehicle. Therefore, brake oil should be replaced every 40,000 kilometers or 2 years.

It should be noted that different types and brands of brake oils cannot be mixed; When moisture is mixed or absorbed in the brake oil, and impurities or deposits are found in the brake oil, the brake oil must be replaced immediately.

06 spark plug

Spark plugs act on engines just like electronic components on lighters. Through high-voltage discharge, the fuel mixture gas in the engine cylinder is ignited, so that the engine starts to run. Usually, the service life of ordinary spark plugs is about 20,000 kilometers, and vehicles need to replace spark plugs every 20,000 kilometers.

07 storage battery

Automobile battery, commonly known as automobile battery, converts chemical energy into electrical energy and provides electrical energy for various electronic systems and engine ignition systems on automobiles. The service life of automobile batteries is usually related to the actual use of automobiles. The service life of ordinary batteries is usually about 3 years. If it is found that the battery is dead and the vehicle cannot catch fire, it is necessary to replace the battery of the vehicle.

08 Brake pads and brake discs

Whether there are problems with the brake pads and discs of vehicles plays a decisive role in the braking effect of vehicles. Therefore, it is very important to replace brake pads and brake discs on time. Brake pads generally need to be replaced once every 40,000-60,000 kilometers, and brake discs generally need to be replaced only after 654.38+ 10,000 kilometers, mainly depending on the actual wear and tear.

09 tire

As the only part of the vehicle that touches the ground, the importance of automobile tires is self-evident, and the life of tires is related to climate, road conditions, driving methods and other conditions. The tire replacement cycle mainly depends on the tire wear, and it needs to be replaced when it is worn to wear marks.

However, it should be noted that due to the aging of rubber, even if the tire can still be used normally, it must be replaced after the service life reaches about 5 years. If the tire is bulging and the injury is serious, the tire should be repaired frequently. It is also necessary to change the tires.
