As the saying goes, "three points of cultivation, seven points of maintenance". In the daily use of the vehicle, it is necessary to actively inspect and maintain it, so as to find and eliminate the hidden faults in the early stage in time, prevent problems before they occur, and keep the vehicle in good running condition.
The temperature plummets in winter, and it is very important to maintain your car in advance, so let's take a look at the precautions for using a car in winter!
1. Heating system
In order to ensure the comfort of the car after winter, you must go to a professional 4S shop to systematically check the fan operation and smooth air duct of the car's heating system before winter. Prevent the occurrence of situations such as the long-term non-flow of antifreeze in the warm air water pipe, and the condensation blocking the circulating pipeline.
2. Cooling system
Cooling system failure is the number one killer of engine failure, accounting for about 60% of the total number of engine failures! The use of antifreeze in winter can effectively curb the occurrence of cooling system icing incidents. Therefore, in winter, we must check or replace the antifreeze in time, and pay special attention to the color of the antifreeze when replacing it.
As far as the choice of antifreeze is concerned, the lower the freezing point, the more resistant the antifreeze will undoubtedly be. At present, the freezing point of antifreeze on the market has several specifications such as -15 °C, -25 °C, -30 °C, -40 °C, etc., and the freezing point should be more than 10 °C lower than the minimum temperature in the region.
3. 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 motor oil will change with the change in ambient temperature. When changing the engine oil in winter, be sure to choose the right one according to the ambient temperature
Motor oil products. Improper oil can aggravate the wear and tear of the engine and mechanical parts, affecting the service life of the vehicle.
Fourth, the battery system
The battery is very "sensitive" to low temperatures, and the battery capacity in a low temperature environment is much lower than that at room temperature. Although the current batteries are maintenance-free, there is no need to replenish the electrolyte of the battery and adjust the specific gravity of the electrolyte. However, before the cold season comes, the binding post of the battery should also be cleaned and coated with special grease to protect it to ensure reliable start and prolong the life of the battery.
5. Air intake system
In the cold winter season, it is very common for the vehicle to fail to start due to excessive carbon deposits such as throttles and air intakes. In winter, because the ambient temperature of the car is lower, the volatilization of gasoline is affected, and the ignition ability of gasoline is relatively weak under the same conditions, and the engine may fail to ignite, or it needs to be ignited multiple times.
Therefore, in winter, do a good job of cleaning the engine throttle, and check the spark plug at the same time to ensure the normal use of the car.
6. Wiper system
In the early morning of winter, the windows are sometimes frosted because of the fog, and even sometimes the wipers are frozen on the glass, at this time, do not force the wipers, not only destroy the wipers, but also damage the glass, and do not use hot water to directly rinse the glass, so it is easy to burst the windows and deform the wipers!
In addition, the use of wiper sprinkler systems in the winter will be significantly reduced, but it cannot be ignored. Especially in the north. Like antifreeze, water and detergent can be used instead in the summer, but in the winter, these alternatives may freeze and should not be used in the winter. In the environment below zero degrees Celsius in winter, the anti-freezing winter glass water should be replaced, or the appropriate proportion of alcohol can be added to the glass water to achieve the purpose of reducing the freezing point and anti-freezing.
7. Lighting inspection of the whole vehicle
As the foggy weather increases in winter, a comprehensive inspection, debugging and replacement of the whole vehicle light system should be carried out in time to ensure that the fog lights, brake lights, turn signals, etc. are in normal working condition, so as to ensure the safety of driving in winter.
8. Tires
Rubber will become hard and relatively brittle due to the decrease in temperature, and the coefficient of friction will decrease. In winter, the tyre pressure should not be too high or too low. The outside temperature is low, the tire pressure is too low, and the soft tire can accelerate aging. In winter, it is necessary to frequently clean up the inclusions in the tread, try to avoid using tires that have been repaired more than once, and replace tires with greater wear and different brands and different patterns. The wear and tear inside and outside the tire is very different, in order to ensure safety and reduce wear, the tire should be regularly balanced with four wheels and the tire position should be replaced.
9. Chassis
In the cold regions of the north, there is a lot of heavy snow in winter, and in order to prevent snow on the road, snowplows often sprinkle a lot of salt on the road surface to accelerate the melting of ice and snow. In this way, the road surface is equivalent to a layer of acidic liquid pavement, and the car is driving on the ice and snow road, and the speeding tires will obviously throw the snow water with high salt content onto the car chassis, and the lack of chassis protection will easily lead to chassis corrosion and rust. Therefore, doing a good job of chassis protection before winter can also extend the service life of your car.
