What if the car won't start in cold weather?

When the weather is cold and the car can't start, we must first find out the reason. Different reasons have different methods:

1, battery power loss

The difficulty in starting a car is usually caused by the battery, because at low temperature, the power consumption of the car will be significantly higher than that in other seasons, and the capacity of the battery will also decrease due to the low temperature environment. In addition, it should be noted that the life of each battery is usually 2-3 years, so the owner should replenish the battery or replace it with a new one in time after entering the winter.

2. The oil flow is blocked

In winter, not only the battery capacity will be affected, but also the oil viscosity will be affected. The lower the temperature in winter, the higher the viscosity of the engine oil, and the more difficult it is for the engine oil to flow, thus increasing the engine resistance and making it difficult for the automobile to start cold in winter.

In this case, the emergency solution is to put the car in a warm environment and start it normally after a period of time. But if you want to solve it completely, you'd better go to a franchise store to do a special winter maintenance and change the appropriate oil according to local conditions.

3, spark plug carbon deposit

Spark plugs are easy to cause problems such as carbon deposition, electric leakage, excessive gap and ablation. After several years of use, it will make it difficult to start the car, and it is difficult to start it cold or even hot, and it often needs multiple ignition. Therefore, when you drive to a certain kilometer or feel that the vehicle is difficult to start, unable to drive, vacillating, increasing fuel consumption or inexplicably stalling, please check the spark plug status and replace it in time.

Winter car maintenance:

1, ice and snow removal skills.

When I went out early in the morning, I found a thick layer of snow on the windshield of my car. Many car owners directly start the wiper to clear the snow after getting on the bus, which will not only not clear the snow, but also cause damage to the windshield and wiper. The correct way is to start the vehicle first, blow the windshield with hot air after the water temperature comes up, then blow the ice on the windshield, and then scrape off the ice and snow residue with a snow shovel.

2, timely replacement of glass water in winter.

After winter, the weather is getting colder and colder, and the lowest temperature in some parts of the north has reached below zero degrees Celsius, so it is necessary to replace the antifreeze glass water in time. The antifreeze glass water should also be selected below the local minimum temperature, otherwise the glass kettle and pipeline will freeze and crack.

3. Warm up the car before driving.

After a cold night, the oil has flowed into the oil pan, but after the hot car, the oil can't be delivered to the piston that needs lubrication most immediately through the oil pump, so it needs to be warmed up. The preheating time should not exceed 1 min, preferably between 30 seconds and 1 min. When driving on the road, step on the accelerator slowly, and you can drive normally after the water temperature rises.

4, ice and snow can replace winter tires.

For cities that snow all the year round in the north, car owners try to choose snow tires, which can ensure driving safety to the greatest extent. If the city where you live is not covered with snow all year round, you can also choose to buy snow chains to use. When it snows, put the snow chains on the driving wheels and take them off when the snow melts. Compared with winter tires, snow chains are cheaper.
