Why do you have a car? The map is the convenience of travel, especially in the winter. In the cold winter months, when you open the door and open the car, you accidentally discover that the car cannot start.
Diagnosis Part I: Battery
The weather turned cold, winter has arrived, and the most direct impact of the winter on the owners of the North is to start the car. At low temperatures, the battery power will be greater than the temperatures in other seasons. This is like the fact that many battery-powered devices in winter use a feeling of insufficient battery power.
Solution: Zhang Naiqi, technical director of Shenyang Zhongba Subaru Hutai Store, said that winter battery will also be affected by the temperature and make the electric capacity lower. Especially when some car owners lose their battery capacity due to business trips or not driving for a long time, they will lose their battery capacity. Will not start up, usually the battery life is 2 years, if the battery is maintained, the service life can be extended to 3 years.
If the battery of some vehicle owners does not have a shelf life, and such a situation occurs, you can only find friends or service personnel of the 4S shop to charge your car battery through the battery or power supply of other vehicles. After the battery is restored, it is best to go to the 4S shop to check the battery to see if there is a fault.
Diagnostic site II: exhaust pipe
In winter, many owners are relatively lazy and will drive for shorter distances. Sometimes due to the short distance near the exhaust pipe, water vapor may be generated due to the temperature difference between hot and cold. Freezing of the exhaust pipe may result in unsmooth start-up of vehicle exhaust. .
Solution: A technician in a car repair shop, Master Zhao, said that the solution to this type of situation is very simple. To solve the ice problem, you must first think of ways to melt the ice in the exhaust pipe, such as pushing the car to a warmer place. , Or use a hot water bottle to melt the ice in the exhaust pipe, then start the car, and do not use the fire to evaporate the exhaust pipe.
If you want to solve this problem completely, it is best for the owner to run a high-speed or long-term car and thoroughly melt and dry the ice and water vapor in the exhaust pipe with high heat.
Diagnostic Site 3: Engine Oil
The car is not used for a period of time, especially in the winter, it is easy to make some of the oil in the car go bad or freeze and block the oil circuit, which makes the engine resistance increase and the starting difficult.
Solution: The peak of a car maintenance shop manager said that in the winter, the car is mainly to the 4S shop to check whether the oil of his car is suitable for winter use, then it must be replaced in time.
For example, it is appropriate to select 5W~40 engine oil for an outside air temperature of -30°C; and for an outside temperature range of ~25°C to 30°C for a 10W-30 engine oil. The heat resistance and cold resistance of 5W~40 are better than 10W~30, but the price will be relatively higher. The owner can select the engine oil according to the local temperature.
