Car care and maintenance knowledge

Mastering certain knowledge about car maintenance is the basic skill of car owners. In daily life, we will discover that, with the extension of the driving experience, everyone’s understanding of car maintenance will also increase. Many problems can be discovered in time so that they can quickly solve.

First, the oil change common sense

How often does the oil change? How much oil does it need to change every time? About the oil replacement cycle and the amount of use is a matter of special concern to everyone, the most direct is to look at their own vehicle maintenance manual, the above are generally very clear introduction. However, many people's maintenance manuals have long disappeared. At this time, you need to know more about them. In general, the oil replacement cycle is 5,000 kilometers, and the specific replacement cycle and usage should be judged based on the vehicle-related information.

Not all models are suitable for owners to change their own oil, but we can learn to see the oil ruler, in order to determine whether the oil to the replacement time. Also, the oil filter must be replaced while changing the oil.

Second, the use of antifreeze common sense

Antifreeze is best used throughout the year, in addition to the function of anti-freeze cooling, antifreeze also has the effect of cleaning, rust removal, and anti-corrosion to reduce the corrosion of the tank and protect the engine. Note that the color of the antifreeze should be selected correctly and do not mix.

Third, the use of brake oil common sense

The function of the brake system is closely related to the brake fluid. When checking the replacement of brake pads, brake disks and other hardware, do not forget to see if the brake fluid needs to be replaced.

Fourth, transmission oil

In order to ensure the flexible steering of the car, it is necessary to check the transmission oil frequently. Regardless of whether it is gear oil or automatic transmission oil, pay attention to the type of oil product, which is usually high.

Maintenance item

What are the daily car maintenance items? The automobile is a very complicated large machine. In the operation, various mechanical components inevitably produce wear. In addition, external factors such as man-made and environment influence the loss of the car. According to the driving conditions of the car, manufacturers will develop corresponding car maintenance items. What are the common maintenance items?

Project I. Small maintenance

Small maintenance content:

Small maintenance generally refers to routine maintenance items that are made at the time or mileage specified by the manufacturer to ensure vehicle performance after the vehicle has traveled a certain distance. Mainly includes the replacement of oil and oil filter.

Small maintenance intervals:

The minimum maintenance time depends on the effective time or mileage of the oil and oil filter used. Different brands of mineral oil, semi-synthetic engine oil, and full-synthetic motor oil have different validity periods. Please refer to the manufacturer's recommendations. Oil filter is generally divided into conventional and long-term two kinds of conventional oil filter with a random oil replacement, long-term oil filter use longer.

Small maintenance supplies:

1. Oil is the engine's running lubricant. Can play the role of engine lubrication, cleaning, cooling, sealing, grinding and so on. It is of great significance to reduce the wear of engine parts and extend the service life.

2. The oil filter unit is the component of the filter oil. Oil contains a certain amount of glial, impurities, moisture and additives; in the engine work process, the metal debris generated by the friction of various parts, the inhalation of air impurities, oil and other oil, are the object of oil filter. If the oil is not filtered, directly entering the oil circuit circulation will have an adverse effect on the performance and life of the engine.

Project two, major maintenance

Major maintenance content:

Major maintenance refers to the routine maintenance of oil and oil filter elements, air filter elements, and fuel filter elements that are performed at the manufacturer's specified time or mileage.

Major maintenance intervals:

Large maintenance is based on the existence of small maintenance, and the two types of maintenance are alternately performed. The interval varies depending on the brand of the car. Please refer to the manufacturer's recommendations.

Large maintenance supplies:

In addition to replacing oil and oil filters, there are two other items in major car maintenance:

1, air filter

The engine must suck in a lot of air during work. If the air is not filtered, the dust will accelerate the wear of the piston set and the cylinder. Larger particles enter between the piston and the cylinder and can also cause serious "pulling". The function of the air filter element is to filter out the dust and particles in the air and ensure that a sufficient amount of clean air is introduced into the cylinder.

2, fuel filter

The role of the fuel filter is to provide the engine with clean fuel, filter out the gasoline moisture and impurities. This allows engine performance to be optimized while also providing optimum engine protection.

Usually, when car maintenance is performed, the operator will perform other inspections based on the specific conditions of the car, and additional maintenance items such as inspection and maintenance of the engine-related system, tire position check, inspection of fastening components, and the like.
