In winter, it is often difficult to start a car. If you encounter this situation, you can try to press the accelerator while turning the key to light the fire. This method is very effective, but when the car starts, you should pay attention to loosen the throttle properly, because excessive stepping on the throttle will cause damage to the car. If this method still fails to solve the problem, there may be the following reasons:
1. The battery is short of electricityIt is the most common reason that makes it difficult to start a car in cold weather. The lower the temperature, the lower the battery capacity. Generally speaking, the life of a battery is about 3 years. When the engine is difficult to start, the headlights are dim or the horn sound is unclear, you should check whether the battery is short of electricity.
2. The exhaust pipe is frozen
It is also a common problem. If the car is used less frequently and the route is shorter, the water vapor after engine combustion will freeze in the exhaust pipe, and short-distance driving is not enough to melt it. After a night, there will be more ice, which will affect the starting and exhaust of the vehicle.
3. Poor performance of engine oil or incorrect selection.
It may also lead to difficulties in starting the car. In winter, the viscosity of engine oil increases greatly, which leads to the increase of internal resistance of engine. Therefore, low viscosity engine oil should be used to cope with the cold weather in winter.
Note that the above method is only applicable to the situation that the car is difficult to start. If the problem still exists, please contact professional car maintenance personnel for inspection and maintenance.
