How to maintain cars in winter?

1. Replace or add antifreeze in time. In winter, the outdoor temperature is very low, so if the vehicle wants to run normally, it must have enough antifreeze, otherwise the water tank will be frozen, and the vehicle will break down. The antifreeze should be between MAX and MIX, and it should be replenished in time if it is missing.

2. Change the glass water in advance. When washing the windshield with glass in winter, you must use good quality glass water so that it will not freeze when washing the glass. Otherwise, it will damage the wiper and affect the driver's sight.

3. Check whether the engine oil is sufficient. The car runs normally in winter, and the engine oil plays a great role. Before winter comes, you must carefully check whether the fuel gauge is within the normal range. See if your car needs an oil change again? You can change the oil according to the mileage in the maintenance manual.

4. Adjust the tire pressure. It's cold in winter, and try to ensure that the tire air of the car is more than that in summer, because the tire is easy to expand with heat and contract with cold. This is the only way to drive comfortably and safely.

5, pay attention to check the battery, battery electrolyte. In the low temperature environment, the capacity of the battery is much lower than that at room temperature. In winter, the battery electrolyte should be replenished in time and the proportion of 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 refrigerated environment for several weeks, the battery should be taken out and stored in a warmer room to prevent the battery from freezing and damaging.

6. Pay attention to the body and chassis. There are many rainy and snowy days in winter. In order to speed up the snow melting, a large amount of snow melting agent is often sprinkled on the road surface. Snow melting agent is very corrosive, and cars are prone to rust when driving on such roads. Therefore, it is necessary to do a good job in anti-rust care of the chassis. At the same time, such rain and snow will also cause damage to the paint surface of the car body, so it is best to wash the car in time, add a protective film to your car in winter, and avoid the damage of snow melting agent to the paint by waxing, sealing or coating.

7, timely check whether the car lighting is normal. In winter, it is necessary to thoroughly check the working state of the whole car lights and replace the black light bulbs as soon as possible. Fog lights, brake lights and turn signals should be checked by themselves. In the foggy morning in winter, visibility is low, and 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.
