【Car owner's car knowledge】As the saying goes, in order to keep your car from getting old, proper maintenance is the most important thing. No matter whether you are buying a used car or a new car, since you have chosen it, it is the car in the minds of consumers, and it should receive comprehensive and careful attention. maintainance. Don't underestimate the first maintenance after buying a used car, it can effectively guarantee the durability of the car and prolong the service life of the second-hand car. Today, I will introduce to you, what is included in the first maintenance after purchasing a used car.
Change oil and oil level
The oil compartment, gasoline compartment, air compartment and air conditioner compartment are commonly known as the "four compartments" of the car. Although they are not very large, they are indispensable in the use of the car. The oil compartment and the gasoline compartment are like human lungs. They filter out the impurities in the oil and gasoline, so that the engine can run normally; the air compartment and the air conditioning compartment are also a filter screen. Without their filtering, no matter how good the car is, it will not go away. No matter how far, no matter how good the air conditioner is, there is also a peculiar smell. Recommended replacement time: The car is replaced every 5000-10000 kilometers. When changing the oil, the oil grid must be changed at the same time to ensure that the oil circuit is not blocked by impurities.
Change gearbox oil
Gearbox oil (that is, the oil that keeps the gear system clean) is the most easily overlooked. After buying a second-hand car, you should replace the gearbox oil that meets the manufacturer's specifications, which is especially important for cars over 5 years old. If it is a rear-drive vehicle, the "tail oil" (ie gear oil) should be replaced together.
Change Cam belt and water pump
If you buy a vehicle that is more than 5 years old or has a mileage of more than 70,000 kilometers, the safest way to deal with it is to replace the engine timing belt with a new one. You can also replace the water pump and belt at the same time. A broken belt would mess up the valve's up-and-down program and collide with the cylinder piston, destroying all of the engine pan top parts. When replacing the Cam belt, the water pump and belt can also be replaced at the same time, which can save a lot of money.
Ensure tire grip
Because some car owners care about the appearance of the vehicle, in fact, the appearance loss of used cars is not large, but the tire loss of frequently used vehicles is not small. When second-hand car owners inspect their vehicles, they should not only pay attention to the texture and cleanliness of the tires, but also ensure the grip ability of the tires. Some may have not changed tires for 3 or 4 years, although the tires seem to be new or the pit patterns are still there. deep, but the gum may have hardened long ago.
Pay attention to cleaning the air conditioner
Automobile air conditioner evaporators, fans, etc. have been in a closed and dark state for a long time, and the internal environment is high temperature and humid. After the impurities, dust, bacteria and viruses in the air enter the interior of the air conditioner, they will bond with the condensed water and block the evaporator and other components. Over time, a large amount of dirt, nicotine, mold, fungi, etc. adheres to it. Molds and fungi multiply quickly and produce rotten odors of organisms. These odors will be mixed with the air-conditioning when the air conditioner is turned on, contaminating the entire interior of the car, and often making drivers and passengers feel uncomfortable. Before using the air conditioner, it is recommended that the car owner clean the air conditioner pipeline and evaporation box.
Check and maintain spark plugs
The service life of spark plugs is 15,000 kilometers, and the service life of long-term spark plugs does not exceed 30,000 kilometers. When the car travels for a certain number of kilometers, the spark plug will produce carbon deposits and the electrode gap will increase. The carbon deposits will increase the fuel consumption of the engine, and the increase in the spark plug gap will cause difficulty in starting. To check the spark plug, you can first look at the burning color, the gap between the electrodes, whether the gap between the porcelain body and the metal shell is leaking, and so on. Therefore, after buying a car, pay attention to checking and maintaining the spark plugs to prolong the life of the engine.
Maintaining the battery
Check the date of the battery, or the status of the display. If you find that the sound becomes weak or the lights are dim when you start the engine, it is a sign that the battery is exhausted, and it is best to replace it as soon as possible. Automotive circuits are mainly divided into two types: low voltage and high voltage. Check the interfaces of various components of the low-voltage circuit to see if the wires are ablated, poor contact, etc., and also pay attention to the condition of the fuse. The life of the battery is about two years, and the life of the spark plug is about 40,000 kilometers.
Stain removal deep waxing
For second-hand cars, it is very important how to maintain the vehicle surface, body paint, and car primer for anti-aging maintenance. After buying a second-hand car, the owner should first go to the car repair center or the after-sales service center of the agent to do it once. Thoroughly remove stains and deep wax or polish to restore the car's luster, which will give the owner the feeling of driving a brand new car.
