The maintenance of cars, including "five oils and three waters" and replacement of parts, covers almost 80% of the content of car maintenance and repair. So as a car owner, it is necessary for you to understand their specific functions and functions. Today, the editor has compiled 15 common spare parts. Let's learn together.

　　Five oils: engine oil, transmission oil (gear oil), brake fluid, steering assist oil, and gasoline; Three types of water: antifreeze, glass water, and battery water.

　　1. The full name of engine oil is engine lubricating oil. The main function of engine oil is to flow through various lubrication points of the engine during operation, reducing wear between engine components and extending the service life of the engine.

　　2. Spark plugs

　　Spark plugs can introduce high-voltage current from the battery into the cylinder, generating electric sparks to ignite the mixed gas in the cylinder, thereby starting the cylinder and starting the engine. Each cylinder must be equipped with at least one spark plug, and some models require two spark plugs per cylinder.

　　3. Oil filter element

　　The oil filter element plays a role in filtering out impurities, gum, and moisture in the oil, providing a guarantee for the quality of the oil. Replace the engine oil together with it.

　　4. Air filter element

　　The function of an air filter is to filter out suspended dust in the air during engine operation, ensuring clean intake. The air filters on cars are mostly made of paper materials, with a replacement cycle of about 10000 kilometers. The specific replacement depends on the usage environment and conditions.

　　5. Air conditioning filter element

　　The function of the air conditioning filter is to filter the dust and pollen entering the air conditioning system when the car is turned on, ensuring the cleanliness of the evaporator and the air inside the car.

　　6. Gasoline filter cartridge

　　Filter out impurities in the fuel to make the mixture entering the cylinder cleaner, which not only protects the engine but also reduces emissions and is environmentally friendly. It is divided into internal and external types.

　　7. The function of power steering oil is to make the steering force of the steering wheel easier through hydraulic action when the owner is turning the steering wheel.

　　8. Glass water

　　This is well-known and used to clean the front and rear windshields or headlights. Glass water is divided into two types: winter and summer glass water. In winter, glass water with a lower freezing point is used according to the local temperature. In summer, glass water is mostly used for cleaning and removing glue.

　　9. Brake fluid

　　Also known as brake assist fluid, it is the medium that transmits brake pressure in the braking system. When you step on the brake, the brake oil generates hydraulic pressure, pushing air to cause friction between the brake pads and brake discs, while also cooling and lowering the temperature.

　　10. When the windshield wiper has windshield washer fluid, it is necessary to use the wiper to clean the front and rear windows. When the wiper fails to clean the water, it needs to be replaced, with a replacement cycle of about 1 year.

　　11. Battery

　　Also known as a battery, its function is to provide power to a car before it starts. Currently, most cars use maintenance free batteries, with a replacement cycle of 2-3 years and a price range of 300-1000 yuan.

　　12. Brake pads

　　Also known as brake pads, they are the actuating components in the braking system. The quality of brake pads directly affects the performance of braking. When the brake pedal is pressed, the brake pads will be squeezed against the brake disc or brake drum, causing friction and preventing the wheels from rotating. Different driving habits can cause significant differences in brake pad wear, and it is recommended to check and replace them in a timely manner.

　　13. Transmission oil

　　Transmission oil is an oil product used to keep the gear system clean, which can ensure the normal operation of the transmission and extend the life of the transmission device.

　　14. Antifreeze

　　Also known as coolant, as the name suggests, its main function is to prevent freezing and dissipate heat from the engine. Of course, antifreeze is not equal to water. The substances incorporated inside can play a role in preventing corrosion and scaling.
