First, stop and start
When parking at night, try to avoid parking the vehicle at the air vent, and try not to drive or hit the throttle immediately after the vehicle starts. Because vehicles are made of metal, especially inside the engine cylinder, after a night of wind blowing and temperature reduction, the metal's heat absorption characteristics and conductivity will cause frosting inside the engine, and the internal temperature will drop very low, not only It will bring great difficulties to the starting of the engine, and the damage to the engine itself is also great. Therefore, try not to drive or throttle the throttle immediately after starting in winter, because the oil is transported to various parts through the oil pump. If it is driven and accelerated without good lubrication, it will definitely cause serious damage to the various parts of the vehicle.
Two, Wiper
If you go out early in the morning and find that the wiper is stuck to the windshield by snow, do not wash it directly with hot water. This will easily cause the windows to burst due to temperature changes and the wiper to deform. The correct method should be to turn on the air conditioner to the hot air, the wind mode is the front windshield, and wait for the wiper to turn on naturally.
Third, the cooling system
In winter, it is necessary to regularly check whether the water tank, pump and belt, water pipe, water supply tank and other components are working properly. If they are damaged or malfunction, it is best to repair or replace them in time. Otherwise, a bucket of antifreeze may be wasted for a small water pipe. Especially in some cars, when the water temperature is too high in summer, the repairman removes the thermostat. Although it can solve the problem in summer, it will be reversed in winter.
Fourth, warm air
When the warm air is left for a summer, it often fails. It is best to try whether there is hot air, whether there is abnormal noise in the operation of the fan, and whether the air duct is smooth. Sometimes the problem is that the antifreeze in the warm air water pipe does not flow for a long time, and the condensate blocks the circulation pipeline. Although it does not affect the traffic, it is very troublesome to maintain.
Five, antifreeze
Check for fluid shortage and deterioration, and replenish or replace if necessary. Antifreeze may seem trivial, but it has a great impact on the car. It may block the pipeline in the light, and may damage the cylinder in the heavy. Therefore, use antifreeze carefully, first, do not mix, and second, do not use fake and shoddy products. In addition, in general, the antifreeze should be changed every two years. If the antifreeze of the vehicle has not been replaced for two years or the water has been added, the owner must go to the store for a freezing point test. If it fails to meet the standard, it should be immediately replace. It is best to flush the cooling system with fresh water before replacement.
Six, oil
After the heavy snowfall, the temperature plummets, and we must pay attention to whether the oil viscosity of the car meets the standard. Because the viscosity of the oil will increase after the temperature drops sharply, it may be greatly affected during cold starts, it is difficult to start, and the engine is difficult to rotate. Therefore, it is recommended that the owner replace the oil with a lower viscosity. Generally, the four seasons oil can carry minus 25 It is about degrees Celsius, so when the temperature continues to decrease, a higher level of oil must be replaced.
Seven, windshield
Keeping the windshield clear is a basic condition for safe driving. In winter, wipe the wipers regularly, and make sure that the windshield can be wiped off in snowy days. If possible, change the anti-freezing windshield to avoid freezing in winter. In addition, glass water can add some windshield de-icing agent. When the windshield freezes, spray the glass of water on it, and the ice will melt. Unlike ordinary glass of water, the spray will become more and more troublesome when it freezes. Use high quality glass water. Because the amount of glass water used after snow will be relatively large, it is recommended that owners add some high-quality glass water to prevent freezing, because the nozzle diameter is relatively small, and it may cause blockage. Once the glass water nozzle is blocked, the owner should not be nervous, you can go to the store to check the freezing point or leave the car in a warm garage.
Eight, Body
Sprinkling salt water on the road after snow, the salt water splashing on the car body is very harmful to the car paint. Before winter, it is best to add a protective film to the car body. Car paint coating or mirror glaze containing Teflon polymer can resist acid rain and snow and salt water erosion. Take precautions in advance, and you won't be afraid to damage the car paint when traveling in snow.
Nine, chassis
In winter, the car chassis always deals directly with rain and snow, and it is easy to rust. Speeding tires throw snowy water on the car's chassis. After the snow cleared, the car's chassis began to rust. Therefore, you'd better take some time to build chassis armor before the winter.
