Nine tips for car maintenance in winter

Nine tips for car maintenance in winter

First, the heating system

Whether the heating system can work normally in winter is undoubtedly very important. In order to ensure the comfort of the car after winter, you must go to a professional 4S shop system to check whether the fan operation and air duct of the car heating system are smooth before winter. Prevent the antifreeze in the warm air water pipe from flowing for a long time and the circulation pipe from condensation and blockage.

Second, the cooling system

Cooling system failure is the primary cause of engine failure, accounting for about 60% of the total number of engine failures! Using antifreeze in winter can effectively inhibit the occurrence of freezing events in cooling system. Therefore, it is necessary to check or replace antifreeze in time when entering winter, and especially remind you to pay attention to the color of antifreeze when replacing it. Different colors cannot be mixed. As far as the choice of antifreeze is concerned, the lower the freezing point, the stronger the antifreeze.

Third, engine oil.

The normal flow of engine oil is an important medium to ensure the normal operation of the engine. The viscosity and fluidity of engine oil will change with the change of external temperature. When changing oil in winter, you must choose the appropriate oil according to the ambient temperature. Improper engine oil will aggravate the wear and tear of engine and mechanical parts and affect the service life of vehicles.

Fourth, the battery system

The battery is very sensitive to low temperature, and the capacity of the battery under low temperature environment is much lower than that under normal temperature. Although the existing battery is maintenance-free, there is no need to replenish the battery electrolyte and adjust the proportion of electrolyte. However, before the arrival of the cold season, the terminals of the battery should also be cleaned and coated with special grease for protection, so as to ensure reliable starting and prolong the battery life.

Verb (abbreviation for verb) intake system

In the cold winter, it is very common that vehicles can't start because of too much carbon accumulation in throttle and air intake. Too much carbon deposits in the throttle itself can easily lead to ignition failure. In winter, due to the low ambient temperature of the automobile, the volatilization of gasoline is affected. Under the same conditions, the ignition ability of gasoline is relatively weak, and the engine may fail to ignite or need multiple ignitions. So in winter, clean the engine throttle and check the spark plug to ensure the normal use of the car.

Sixth, the wiper system.

In the early morning of winter, the windows are sometimes frosted by fog, and even the wipers are sometimes frozen on the glass. Never turn on the wiper by force at this time, which will not only damage the wiper, but also damage the glass, and never wash the glass directly with hot water, which will easily burst the window and deform the wiper!

In addition, the usage of wiper spray system will be significantly reduced in winter, but it cannot be ignored. Especially in the north. Like antifreeze, although it can be replaced by clean water and washing water in summer, these substitutes may freeze in winter, so don't use them in winter.

In the environment below zero degrees Celsius in winter, the frost-resistant winter glass water should be replaced, or an appropriate proportion of alcohol should be added to the glass water to achieve the purpose of lowering the freezing point and freezing resistance.

Seven, the whole car lighting inspection

With the increase of foggy weather in winter, it is necessary to conduct comprehensive inspection, debugging and replacement of the vehicle lighting system in time to ensure that fog lights, brake lights and turn signals are in normal working conditions and do a good job in driving safety in winter.

Eight, tires

Rubber will become hard and brittle due to the decrease of air temperature, and the friction coefficient will decrease. The tire pressure should not be too high or too low in winter. When the outside temperature is low and the tire pressure is too low, the soft tire will accelerate the aging. winter

During the season change, 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. The internal and external wear of tires are completely different. In order to ensure safety and reduce wear, the tire should be dynamically balanced with four wheels regularly, and the tire position should be changed.

Nine, chassis

In the cold areas of the north, there is more heavy snow and steam in winter. In order to prevent snow on the road, snow sweepers often sprinkle a lot of salt on the road to accelerate the melting of ice and snow. In this way, the pavement is equivalent to a layer of acidic liquid pavement. When the car is driving on the ice and snow road, the speeding tires will obviously throw the snow water with high salt content onto the chassis of the car. Insufficient chassis protection can easily lead to chassis corrosion and rust. Therefore, the chassis protection before winter can also extend the service life of the car.
