Small maintenance items
engine oil
Oil is also called lubricating oil, and its function is to lubricate, cool, dampen and reduce wear and tear of the engine. Therefore, oil is also called the "blood" of the engine. There are three types of oil:
Fully synthetic motor oil: The advantage of fully synthetic motor oil is that fully synthetic motor oil has better high and low temperature performance, longer oil change interval and is suitable for more severe vehicle conditions, but relatively, the price of fully synthetic motor oil is also higher than other types of motor oil be higher. Generally, it is replaced at about 10,000 kilometers. If it is not driven frequently, the oil will also be emulsified and lose its effect. It also needs to be replaced in about a year.
Semi-synthetic oil: The replacement cycle of semi-synthetic oil is generally around 8,000 kilometers, and its price and performance are relatively balanced.
Mineral engine oil: This type of engine oil generally needs to be replaced at about 5,000 kilometers. Compared with semi-synthetic engine oil and fully synthetic engine oil, the price difference is not large, so it is not recommended to use this type of engine oil.
three filter
The oil filter, air filter and air conditioner filter together are called the three filters of the car. The function of the oil filter element is to filter the oil to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil and protect the engine. Its replacement cycle is the same as that of the oil. Every time the oil is changed, it needs to be replaced this filter.
As the name suggests, the air filter is to filter the air to ensure the cleanliness of the engine intake. Generally, it is replaced every 20,000 kilometers or about 2 years. Every small maintenance needs to be blown with air to ensure the cleanliness of the air filter. The function of the air conditioner filter element is to filter the indoor air to prevent dust and odors from outside the car from entering the car and affect the driving environment. The same is to be replaced every 2 years or 2 kilometers.
Major maintenance items
antifreeze
Antifreeze is also known as coolant, and its main role is to prevent freezing in winter, prevent boiling in summer, and prevent scale and corrosion. The general refrigerant replacement cycle is about 4 years and 60,000 kilometers. When checking the refrigerant, there are two symbols of max (most) and min (minimum) on the refrigerant container. When replacing the refrigerant, the capacity of the refrigerant cannot exceed the max, and if the refrigerant is lower than the min, the Indicates that it is time to add refrigerant.
Brake Fluid
There is a more obvious mark on the brake fluid filler port, that is, a circle in a bracket. Due to the inherent properties of brake fluid, it absorbs water. Therefore, after a long time of use, the oil and water are separated, and the boiling point is different, the performance will be reduced, and the braking effect will be affected. It is recommended to change the brake fluid every major maintenance (about 40,000 kilometers). Of course, the replacement cycle can be shortened accordingly according to different personal car conditions.
power steering oil
Steering power oil is a special liquid used in the steering power pump of automobiles. Through hydraulic action, the steering wheel can be made very light, similar to automatic transmission oil, brake oil and shock absorption oil. It is also replaced during major maintenance.
petrol filter
It can filter impurities in gasoline and prevent impurities from entering and damaging the EFI system. If it is too dirty or clogged, it is generally manifested as weak acceleration and difficulty in starting. Now it is generally a built-in filter element (replaced at about 80,000 kilometers), if it is an external filter element (recommended to be replaced at about 20,000 kilometers).
spark plug
The spark plug is also an item that must be understood in every major maintenance, because the function of the spark plug is to ignite the combustible mixture in the cylinder. Once the working time is too long, it will make the engine run unevenly and cause jitter, and even cause a lack of cylinders. It will not catch fire, and it will also make the engine more fuel-efficient, so the role of the spark plug is very important.
And now there are three types of spark plugs: iridium spark plugs: 8-100,000 kilometers to replace. Platinum spark plugs: 50,000-60,000 km replacement. Nickel spark plugs: 20,000-30,000 km replacement.
gearbox oil
Transmission oil is an oil product that keeps the gear system clean, which can ensure the normal operation of the transmission and prolong the life of the transmission. Now, some gearboxes are maintenance-free for life, while others require regular oil changes. After changing the gearbox oil, the gearbox will shift more smoothly, and at the same time, it can prevent the gearbox from shaking and abnormal noise. , jumping gears, failures such as failure, so in a specific cycle, the transmission oil still needs to be replaced. The replacement cycle of automatic transmission oil is about 80,000 kilometers, while the replacement cycle of manual transmission oil is about 120,000 kilometers.
brake pads
Strictly speaking, there is no specific replacement cycle for brake pads, because this is a wearing part, and the pressure on the brake pads varies according to the usage. Therefore, when replacing the brake pads, we should pay attention to the thickness of the brake pads, and then consider whether it needs to be replaced. The general replacement time is about 40,000 kilometers. If you are a car owner with a softer driving style, you can extend it to 60,000-80,000 kilometers. km, but the most important thing is to always pay attention to the braking ability of the vehicle and the condition of the brake pads, and replace the brake pads according to the situation.
battery
When the vehicle is driving normally, the replacement cycle of the battery is generally about 40,000 kilometers. If you feel that the vehicle is weak to start, it means that there may be a problem with the battery. At this time, the battery should be replaced in time. At the same time, Brother Bing advises everyone not to turn on the headlights or play music loudly after the vehicle is turned off, which will deplete the battery power. When you want to start a fire, you find that there is not enough power to ignite, which is very embarrassing.
In general, in the face of car maintenance, in addition to the original maintenance items of the vehicle, it is also necessary to inspect the vehicle to determine whether other parts of the vehicle need to be maintained and replaced, and the 4S shop will also do a comprehensive inspection of the vehicle. Check and give maintenance advice to the owner. However, in the process of daily car use, we also need to pay attention to the condition of the vehicle at all times. When the vehicle has a problem, we will make a response plan in time to ensure the normal driving of the vehicle.
