Antifreeze and lubricating oil specifications 1. Antifreeze is to ensure that the vehicle's cooling system can work normally, and appropriate antifreeze should be added. Antifreeze should be selected according to local environmental conditions. The freezing point should be about - 10 ° C ~ 15 ° C lower in winter. If the local temperature is - 30 ° C, we should choose - 45 ° C as the freezing point of antifreeze; In addition to antifreeze, antifreeze can also prevent rust, corrosion, water scale and boiling, so vehicles in the South also need to add appropriate antifreeze.
2. Lubricating oil (the winter code of lubricating oil is w. the smaller the number before W, the smaller its low-temperature viscosity, the better its low-temperature fluidity, and the lower the applicable low gas temperature).
The longer the warm-up time is, the better. The warm-up time in summer and winter is required, and the warm-up time in winter is longer than that in summer. However, it should be emphasized that the longer the hot car is, the better. As long as the engine can reach stable and normal idle speed, you can drive. Idling a hot car for too long not only increases fuel consumption and carbon deposition, but also is not conducive to environmental protection. In addition, after the hot car, be sure to drive slowly in low gear, and slowly change to high gear to increase the speed according to the engine condition and vehicle condition. OK, wait until the water temperature reaches the second grid (60 ℃) of the water temperature gauge, and then drive at the normal speed.
After washing the car, ensure that the car is dry and the weather is cold in winter. It is recommended that the car owner go to the computer car wash room to wash the car, because the computer car wash machine has a drying procedure, which can dry the water droplets left in the gap of the car body. Coupled with manual drying, the dried car body will not freeze again.
If you really don't want to spend too much money to go to the computer car wash room, tell you another way. Don't park your car after washing the car. Drive the car and let it drive on the road for a period of time. In this way, with the driving of the car, the residual water droplets in the door will be thrown out. In addition, when the car is driving, the air conditioner can be turned on, which is conducive to drying the residual water in door cracks, window cracks and other parts, and the probability of icing is greatly reduced.
Try not to use the wiper to remove snow. If the car body is full of snow, the owner must not use hot water to flush. When the hot water contacts the car paint and glass at a low temperature, it is likely to cause damage to the car paint and glass.
The correct way is to use a basin of warm water to pour the front and rear windshield and window glass. When the snow that does not affect the line of sight is removed, you can drive on the road first. With the increase of vehicle temperature, the snow on the body will naturally melt slowly.
In addition, some car owners use the wiper to remove snow. If there is ice between the wiper and the glass, it is likely to damage the wiper motor and the wiper blade. In addition, glass water should also be selected with antifreeze function.
Don't park at ponding in snowy days. In winter, especially in snowy days, vehicles often freeze after parking for one night. If you have to park the car outdoors, you can't park it where there is ponding, because if you park in these places, the ponding will freeze again at night, freezing the tire and the road together, which will deform the tire tread and even tear the tire directly when starting the vehicle.
In addition, parking in the open air on a snowy night is better than pulling the handbrake. In order to prevent the vehicle from moving, the manual transmission vehicle can shift to forward gear or reverse gear, the automatic transmission vehicle can shift to parking gear, and choose to place stones or wooden wedges on the two tires at the opposite corners.
Maintain the driving distance, that is, our usual driving habits, the speed we can control and the driving distance. There is no big difference between the South and normal times. In the north, due to the cold weather, when it rains and snows, the distance between cars should be kept at least 80m. The road is too slippery, and the distance should be appropriately lengthened. In case of emergencies, let's have a braking distance. In dark places, ramps, bridges and small intersections are easy to freeze. Be more careful when driving in these sections and control the speed.
At the same time, overtaking is strictly prohibited. It is foggy in winter in the south, and sometimes there is oily light. Keeping the distance between vehicles is the guarantee. Overtaking is more dangerous than usual; The snow and ice roads in the north will be more slippery in winter, so it is not suitable to brake vigorously. The road conditions in winter are more complex than usual. See the driving track of the vehicles ahead and observe the road conditions more.
Before using the vehicle, check the correct use of lights. Before driving in winter, check the vehicle, tires and vehicle glass. If there is ice or snow on the glass, clean it outside first. Start the vehicle and warm up the vehicle for no more than 1 minute, then drive at a low speed. When the water temperature increases to close to the normal temperature, accelerate to the normal speed per hour (turn on the warm air to remove the fog of the glass in the vehicle at the same time).
If driving in fog, be sure to turn on the side marker lamp and fog lamp in time, reduce the speed and keep a distance from the car in front.
In the cold winter, cars become a warm haven for us when we go out. In low-temperature weather, wind and snow, the care of your car can make it survive the winter safely and avoid the adverse impact of low temperature on your car. At the same time, it is more important for us to master how to drive in winter. I hope the above contents are helpful to your car health. Remember to pay more attention to driving in winter
