People need to keep healthy. We often say that autumn and winter are the time for people to make up for it, in order to have a better physical condition in the coming year. Cars also need maintenance. Our cars, like people, need good supplies and maintenance in autumn and winter to ensure normal road driving.

1. Change the oil. When the temperature is low, the engine oil will become sticky, which will make the oil flow worse, weaken the lubrication of vehicle parts and engines, and accelerate the wear of vehicles. Therefore, in cold weather, it is necessary to consider replacing the low-temperature freezing-point resistant oil. You can choose engine oil whose freezing point is 5~7C lower than the local temperature, which will protect the engine system.

2. Change antifreeze. Antifreeze is a maintenance project to prevent vehicles from being "frostbitten" in autumn and winter, which can prevent engine oil from freezing, damaging engine cylinders and affecting the normal use of vehicles. In addition, the engine system is made of copper, iron, tin and other metals, which will be corroded and rusted by chemical components in engine oil after long-term operation. Adding antifreeze can prevent the engine from corrosion and rust.

3. change a glass of water. Ordinary glass water is not suitable for winter use. Ordinary glass water does not have anti-freezing ability. When washing glass, it will freeze on the glass and affect the line of sight. When the temperature is low, there is glass water specially configured for vehicles, so as to keep the vehicle glass from freezing at a low temperature of about-15, so that people can have a good view when driving.

Low temperature maintenance. The cold weather in autumn and winter is not only a test of vehicle tires, but also a test of the performance of various engine systems. In cold weather, not only the tires should be maintained, but also the engine oil and glass water suitable for low temperature environment should be replaced in time, and antifreeze should be added to ensure the normal operation of the vehicle.
