What should I pay attention to when buying a car in the weather of MINUS 40 degrees in winter in Northeast China?

Car maintenance methods are different in different seasons. When the cold winter has arrived, while enjoying the northern scenery and the frozen scenery thousands of miles away, we should also consider how to maintain our car from being damaged in winter. Winter is a high incidence of car failures, and new cars are fine. After a long time of use, all parts began to age and become fragile. If not maintained and replaced in time, it may break out in winter.

The first thing to pay attention to is the tire.

Accurately speaking, when the temperature drops to 7 degrees Celsius, the rubber of ordinary tires will start to harden, and the grip and braking performance of tires will decrease. For example, in Northeast China, the temperature is MINUS 30 degrees in winter, the toughness of ordinary tires becomes weaker and the hardness becomes stronger, and the contact surface between the tread and the ground becomes smaller, so the tire pressure cannot be evenly distributed. In this way, the grip effect will be reduced, and tire slippage will easily occur.

This leads to the appearance of winter tires, which are specially designed for snowy and slippery roads and cold temperatures in winter. In winter, the tire is made of relatively soft materials, and the tread groove is relatively wider and deeper, which can provide stronger grip and skid resistance on ice and snow roads, ensure the adhesion of cars on low-temperature roads, and provide shorter braking distance and better grip for wheels when driving on dry, cold, slippery and snowy roads in winter.

The second thing to note is: hot cars in winter.

Hot car is a cliche, and riders in the north and south have different opinions. In fact, there is no need for everyone to struggle. It is scientific to judge whether it takes a long time to warm up the car according to the local environment. For example, the weather in the north is cold and it snows from time to time, so riders have to warm up their cars in the cold start! The same is true for riders in the north. As for the riders in the south, it depends! It should be noted that hot cars and cold cars should not step on the accelerator deeply to accelerate and keep driving at a low speed. After the temperature comes up, it can run normally. Remember, hot cars are important, but they don't last long. It usually takes about 60 seconds.

The diagnosis of the above three faults should follow the principles of power first, engine first, simplicity first and complexity second, and attention should also be paid to cleaning up the carbon deposits in the engine. Generally speaking, the difficulty of vehicle starting and idling jitter are mostly caused by carbon deposition in various parts of the engine. Maintenance before winter comes, you may wish to clean up the carbon deposit for your car and make it more comfortable for the winter.

The third note is antifreeze.

Be sure to use antifreeze in winter, especially in the cold north. If the cooling system of the engine is ordinary water, it is easy to freeze, which is not conducive to the start of the car and will almost cause serious damage to the engine.

The fourth point to pay attention to is the order of electricity use.

In winter, the vehicle should be ignited first, and then the electric equipment such as headlights should be turned on after the engine works normally; When parking, turn off the electric appliance first, and then turn off the engine; Try not to consume a lot of electricity when parking, especially electric windows, headlights, stereos and other power-consuming equipment.

Winter is coming, in addition to buying it for yourself at buy buy, you should also pay attention to keeping your car warm.

The fifth point to note is: turn on the warm air when parking for a long time.

This practice directly harms the body and may seriously endanger life! Some people may have the habit of sleeping in a car with warm air when waiting for someone in the basement, or when parking idle. It's so comfortable However, heating the warm air for a long time will lead to carbon monoxide poisoning, so be sure to expose a gap in the window, which will not affect the temperature inside the car and will not worry about poisoning! This is not only harmful to people's health, but also leads to a large amount of carbon deposition in the car.

Vehicles are more prone to problems in winter, which brings more trouble to the owners. Usually, we say that cars need "three-point repair and seven-point maintenance" in winter, and nursing is the key. Just as people need to keep warm in winter, cars need to be well maintained in winter!
