First, the common sense of automobile antifreeze maintenance in winter
When winter comes, the amount of antifreeze must be appropriate. Experts suggest that antifreeze should be changed once every two years, but mixed antifreeze must be changed once a year. In use, it should be noted that different brands and models of products cannot be mixed. Followed by engine oil, the lubrication requirements for automobiles are higher in winter. If the oil is used in summer, it must be replaced and will be used for a long time.
The oil with black color and poor adhesion should be replaced to ensure the smooth start of the engine.
Second, the common sense of automobile battery maintenance in winter
Batteries are most afraid of low temperature. At low temperature, the capacity of storage battery is much lower than that at normal temperature.
Therefore, before the arrival of the cold season, the electrolyte of the battery should be replenished and the specific gravity of the electrolyte should be adjusted. At the same time, clean the terminals of the battery and apply special grease protection to ensure reliable starting and prolong the battery life. If the vehicle is parked in the open air or garage for several weeks, the battery should be taken out and stored in a warmer room to prevent the battery from freezing and damaging.
Third, common sense of winter maintenance of heating system
Winter is the season when warm air is used, and the heating system will break down if it stops for a long time. Experts suggest that car owners should first try whether there is hot air, whether the fan is operating abnormally and whether the air duct is unobstructed. In the interview, experts said that sometimes the antifreeze in the warm air pipe does not flow for a long time, and condensation blocks the circulation pipe. Although it does not affect driving, it is very troublesome to maintain, so it must be repaired in time if there is a problem. Fourth, common sense of gasoline maintenance in winter
As for fuel, experts suggest that car owners can replace high-standard gasoline in winter. If you usually use 90 # gasoline, you can change it to 93 # gasoline. Because of the low ambient temperature of cars in winter, the ignition point of high-standard gasoline is higher and the ignition ability is stronger.
Five, automobile body winter maintenance common sense
Experts suggest that car owners should give their cars a full-body "beauty" before winter. Waxing in early winter is a good way to maintain car paint, because it is freezing in winter, and the number of car brushing will be reduced. In addition, the waxed car body is not easy to get wet, and it is not easy to condense into ice in winter.
Six, glass cleaning liquid winter maintenance knowledge
Although the consumption of glass cleaning liquid will be significantly reduced in winter, it can not be ignored. Some car owners use clean water in other high-consumption seasons, but those substitutes often freeze in winter, so they can't be used in winter. Experts suggest that in the environment below zero degrees Celsius in winter, the antifreeze winter glass cleaning liquid should be replaced, or an appropriate proportion of alcohol should be added to it to achieve the purpose of lowering the freezing point and freezing resistance.
Seven, winter car bulb maintenance skills
For light bulbs, experts advise car owners to replace the black light bulbs in the headlights as soon as possible, and also check the fog lights and brake lights. Frost is easy to appear in winter and visibility is low.
There are many rear-end accidents, so whether fog lights and high-position brake lights work normally is also the guarantee of driving safety in winter.
Eight, automobile tire maintenance methods in winter
Because the rubber of the tire is hard and brittle in winter, the friction coefficient will be reduced, and the tire pressure should not be too high, but it should not be too low. Because the outside temperature is low and the tire pressure is too low, soft tires will accelerate aging. In addition, in winter, it is necessary to regularly clean up the inclusions in the tire tread, try to avoid using tires that have been mended more than once, and replace tires with larger wear and different brands and patterns. There is a great difference between the internal and external wear of tires. In order to ensure safety and reduce wear and tear, tires should be replaced regularly.
Pay attention to car washing in winter
In cold weather, water droplets often turn into ice, so the biggest taboo when washing a car is that water droplets freeze on the vehicle. It is best to wash directly with warm water, not cold water. When washing the car with a hose, don't use a hose nozzle to spray water at the joint of the lock hole, the door and the trunk lid to avoid freezing at low temperature. After cleaning, open the door and dry the water in time to prevent the residual water in the door from freezing the door.
