How to maintain a used car?How to maintain the used car you just bought

【The owner's family car knowledge】Nowadays, there are more and more people buying second-hand cars. For second-hand cars, you should pay attention not only when you buy them, but also pay attention to maintenance after you buy them. Second-hand cars are not like new cars. New cars are being bought because they have not been used. After returning, pay attention to the running-in problem, and the maintenance is relatively simple, but the second-hand car is not the same. Although the second-hand car will not have the running-in problem, some second-hand cars have been used for a long time, and many parts are aging or severely worn. After you buy it, you need to go through many aspects of maintenance to extend its service life. Then what aspects of maintenance do you need to go through after buying a second-hand car? I will introduce to you here.

1. Check the tires and spare tires

The tires of second-hand cars generally have serious wear and tear. Many second-hand car tires that are bought are generally more or less damaged, unless the seller has replaced new tires, and the spare tire may also be used for a long time or improperly maintained. This leads to rubber hardening or other defects, and some even do not have a spare tire, so everyone should check the condition of the tire and the spare tire, and deal with or replace it in time.

2. Replace oil and water

After the second-hand car is bought back, many of the "liquids" are impure or useless, so they need to be replaced in time, such as gearbox oil, brake oil, engine oil, water tank cooling water, etc. In addition, it is reminded to change the oil grid while changing the oil to prevent impurities from blocking the oil circuit. In addition, remember to change the gearbox oil, especially for cars over 5 years old. If it is a rear-drive car, change the "tail gear oil" by the way. Remember that the oil changed above must meet the factory specifications, and don’t match it randomly. .

3. Change the timing belt and water pump

If you buy a car with a mileage of more than 70,000 kilometers or more than 5 years of service life, it is best to replace the engine timing belt. Remember to also replace the water pump and its belt, because if you change it early, you can reduce the internal wear of the car. , To reduce the later car maintenance costs.

Summarize: Since you don’t use a used car all the time, you don’t know much about the situation of the car yourself. You have to spend a lot of time on maintenance and repair, so try your best to pay attention to the things you need to pay attention to when there are no problems. Check it first, it will be very helpful for the longevity of the car and safe driving.
