This is due to a lack of coolant. Below is an introduction to coolant: 1. Definition: The full name of coolant should be antifreeze coolant, which means a coolant with antifreeze function. Coolant can prevent the cooling liquid from freezing when parking in cold winter, which may cause the radiator to crack and the engine cylinder block to freeze. 2. Function: It plays a role in anti-corrosion protection for the components of the cooling system. It prevents scale formation, avoiding the reduction of the radiator's cooling effect. It ensures that the engine can operate within the normal temperature range. It must have the characteristics of antifreeze, anti-boiling, anti-corrosion, anti-scale, and no foam, and is not affected by seasons or regions.

How to Adjust the Correct Position of Rearview Mirrors?

Methods for adjusting the correct position of rearview mirrors: 1. Adjustment of the left rearview mirror: For the up and down position, place the distant horizon in the center, and adjust the left and right position so that the car body occupies one-fourth of the mirror's area; 2. Adjustment of the right rearview mirror: For the up and down position, the ground area should be larger, occupying about two-thirds of the mirror's area, and similarly adjust the left and right position so that the car body occupies one-fourth of the mirror's area; 3. Adjustment of the central rearview mirror: Adjust the left and right position to the left edge of the mirror, aligning it to the right ear of your reflection in the mirror. Generally, the car owner should not be visible in the central rearview mirror. For the up and down position, place the distant horizon in the center of the mirror. The key adjustment points are to place the horizon in the middle and your ear on the left edge, meaning the distant horizon should be horizontally aligned with the center line of the central rearview mirror, then adjust left and right to place the image of your right ear at the left edge of the mirror.

How to Warm Up a New Car in Winter?

Introduction to car warming methods in winter: Do not press the accelerator to warm up the car. When starting a cold engine, the idle speed is protected by the system, and the engine will operate at a higher RPM before gradually dropping to 750-800 RPM. Therefore, you only need to let the vehicle run on its own. Here are the reasons why a car needs to be warmed up: 1. After prolonged parking, the engine oil flows back into the oil pan at the bottom of the engine. Thus, when starting, the upper part of the engine lacks lubrication. It takes about 30 seconds after ignition for the oil pump to circulate oil to critical components like pistons, connecting rods, and crankshafts. 2. In winter, engine oil becomes thicker and less fluid. Idling allows the oil to re-coat engine components. Again, avoid pressing the accelerator to warm up the car. The engine's idle protection during cold starts ensures it runs at a higher RPM before gradually settling to 750-800 RPM, so simply let the vehicle run on its own.

If the small battery of a new energy vehicle runs out of power, can the whole vehicle still be charged?

If the small battery of a new energy vehicle runs out of power, the whole vehicle can still be charged. When the car battery is out of power, it should be charged promptly. At home, you can use a charger to recharge the battery. Typically, the battery capacity of a household car is around 60Ah, and the required charging current is one-tenth of the battery capacity, which is 6A. Charging at this current usually takes about 3-5 hours to fully charge. The advantages of new energy vehicles are as follows: 1. Environmental protection: New energy vehicles mainly use non-fuel power devices, avoiding the burning of gasoline, diesel, etc. Instead, they utilize clean energy sources such as electricity, solar power, and hydrogen, thereby reducing the emission of gases like carbon dioxide and contributing to environmental protection. 2. No license plate restrictions: Due to severe environmental pollution, many cities implement license plate restrictions to reduce environmental pressure by limiting the use of private cars. However, new energy vehicles are almost zero-pollution and zero-emission, so they are not subject to these restrictions, making travel more convenient. 3. High efficiency: New energy vehicles generally adopt new technologies and structures, making them more efficient.
