Generally, when the temperature is between -10°C and -15°C, it will already be difficult for the car to start from cold.
If the temperature drops below -40℃, the car will be difficult to start. Generally speaking, the engine oil in the car is the key to whether the car can start. the lower the temperature, the higher the viscosity of the engine oil will be, and if the viscosity is high and the fluidity is poor, the car will be difficult to start. In winter, it is best to heat the car to start it. the car for the best safety.
If the temperature is below zero and the car is frozen and cannot be used, you can move the gasoline car under the sun and open the hood to bask in it, allowing the car gasoline to absorb heat from the sun and thaw naturally; pour an appropriate amount of lukewarm water over the tankwater of a gasoline car, let the temperature in the water tank of the gasoline car rise, accelerate the circulation of water in the car and let it flow. let the car thaw naturally; drive the car into a warm storage room for a few days to allow the car's temperature to rise and thaw.
How to prevent
1. Change the engine oil on time: The engine is greatly affected when the car is placed outdoors. I think everyone knows that. the generator is very important for a car, for a car it is the heart, which occupies a dominant position. The quality of the alternator directly determines the quality of the car. If the temperature is too low in winter, the activity of the car. the oil in the alternator will be significantly reduced, making it more difficult to start the car. Generally, in winter, it is best toreplace the winter oil with an oil with a low freezing point.
2. Replace the antifreeze water in time: The car window is often frozen. In winter, the glass should be cleaned and inspected, and the antifreeze water should be replaced to prevent the temperature from dropping. too low, which may damage the water pump and pipes, affecting the normal operation of the car.
3. Check the coolant timely: Coolant is a consumable product that can help the vehicle cool, clean, and prevent corrosion and rust. When the temperature is low in winter, the demand for coolant. will be higher and the coolant level should be checked regularly. Check and if the height is not enough, it must be filled in time.
4. Check tire pressure in time: low temperatures in winter will cause tire pressure to dropof the car. If you are not careful, it can easily cause the tire to rupture, so you need to check the pressure. Tire pressure frequently. If you find that the tire pressure of the car is too low, it should be increased in time.
