How to maintain the car in cold weather? What are the maintenance skills?

After entering the cold weather, the temperature dropped sharply. At this time, the maintenance of the car can not be underestimated. Under normal circumstances, the car needs to maintain the wiper, warm air, engine oil, body, battery, cooling system, antifreeze, windshield, chassis and tires in winter. In terms of maintenance skills, try to follow the rules of safe use of automobiles and carefully protect the above parts that need special maintenance.

It is very important to maintain the wiper and warm air in cold weather. After the cold weather, due to the sudden drop in temperature, car owners and friends will find that the wiper is easily stuck on the windshield by rain when driving in the morning. At this time, we can't directly wash the wiper with hot water, which will easily lead to the windshield breaking or the wiper breaking.

The correct way is to set the air conditioner in the car to the front mode of hot air blowing, so that the wiper can be automatically turned on slowly. When turning on the internal air conditioner in cold weather, pay attention to whether the fan is running abnormally. First, check whether the antifreeze in the heater pipe is in liquid state. If the circulating pipe is blocked due to condensation, it will be difficult to maintain, and it needs to be heated in advance, so that it will be smoother when the warm air is turned on.

Protect the engine oil and body in advance to avoid driving failure. Before it gets cold, the car body needs protection. If possible, the car body can be coated with a film, and you can choose car paint film or mirror glaze. These two kinds of membranes can resist the corrosion of acid rain and make the car look cleaner. After snowing, the road surface will be sprinkled with salt particles, and the mixed salt water of flying sword blood and water will easily damage the car paint when driving, so it is necessary to clean the car body in time.

Under normal circumstances, in cold weather, automobile oil will become sticky easily because of supercooling, which will affect the starting effect of the automobile. In cold weather, you must choose high-quality compound oil, and you can change the type of automobile oil in advance before it is cold, so that the car can run more smoothly.

Check the car battery and cooling system in advance to ensure safety. The low temperature in cold weather is harmful to automobile batteries. Car batteries are afraid of low temperature. Before the arrival of cold weather, the proportion of electrolyte can be adjusted in advance, and special grease can be coated on the terminals of the battery to protect the automobile battery and make it start normally.

If the car is placed in the open air for a long time and the temperature is low, the battery should be removed in time to avoid freezing. In cold weather, the frequency of cooling system is not high. At this time, it is necessary to regularly check the water tank, water pump and belt to see if there is any fault and repair it in time to avoid cylinder explosion when it is used again in summer.

Antifreeze should be added in time, and the windshield and chassis should be cleaned in time in cold weather. The car must be added with antifreeze, which is used to help the car engine cool down. If the antifreeze is insufficient, it is likely to block the pipeline and even corrode the cylinder. Replace antifreeze as early as possible. When the car is in cold weather, it is necessary to regularly scrub the wiper and windshield, and spray some glass water on it for cleaning to avoid freezing due to the low weather temperature. Regarding the chassis of a car, it is best to do rust prevention treatment before winter to avoid damage to the chassis caused by the erosion of snow water.

In short, drivers and friends need to pay special attention to the maintenance of the car in cold weather, because the temperature is too low, which will cause great harm to all parts of the car. It is necessary to take preventive measures in advance, pay more attention to the above maintenance contents, repair faults in time, and drive safely for the winter.
