The reason why coolant leaks more easily in winter is: frequent use of the heater in winter causes the coolant to evaporate and decrease in volume. Composition of coolant: The main components of coolant are: 50% purified water, 40% methanol, and 10% other substances. Types of coolant: Coolants are generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can different coolants be mixed? It is necessary to use the same brand of coolant. Different brands of coolant may have different production formulas. If mixed, chemical reactions between various additives are likely to occur, rendering the additives ineffective. How to choose coolant: The basic indicators of coolant are freezing point and boiling point. The freezing points of coolants available on the market include -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.

How Deep of Water Can a Car Safely Drive Through?

For ordinary sedans, when the water level reaches above 20 centimeters (for SUVs with higher ground clearance, this threshold may increase to 30 centimeters), there is a risk of water entering the engine. This represents the maximum wading depth. Below is relevant information: 1. Engine Water Intake Pathways: There are two main ways water can enter the engine: First, due to the low position of the engine air intake inlet, water can be sucked into the engine during wading; Second, when the exhaust pipe outlet is below the waterline, water can be drawn into the engine through the exhaust. 2. Handling Methods: After water enters the engine, it will inevitably cause the engine to stall. Since water in the cylinders lacks lubricating properties, attempting to restart the engine blindly after stalling may lead to severe engine damage or complete failure due to cylinder scoring. The correct approach is to push the vehicle to a higher, water-free area, contact your insurance company, and then have the car towed to a repair shop for inspection of water damage.

Do You Need to Manually Release the Electronic Parking Brake When Starting an Automatic Transmission Car?

Starting the car requires releasing the electronic parking brake in an automatic transmission vehicle. Here is some information about the electronic parking brake in automatic transmission cars: 1. Function: Compared to traditional handbrakes, the electronic parking brake not only saves space but also provides convenience for drivers who may not have much strength. It offers a more stylish design and more elegant operation. If a mechanical handbrake is not fully engaged, the car may still roll, but with the electronic parking brake, simply pressing a button prevents the car from rolling backward. Additionally, the electronic parking brake includes an auto-hold function, which is a feature that mechanical handbrakes cannot provide. 2. Principle: The electronic parking brake operates on the same principle as the mechanical handbrake, but it is controlled directly by the computer system. It still requires manual release when starting the car. When the vehicle speed is below 20 km/h, the computer system automatically determines that the car is in a braking state and locks the electronic parking brake. If the brake is not manually released before starting, the brake line may break.

What is the reason for the Edge displaying 'USB not responding'?

Edge displays 'USB not responding' due to reasons such as a blown fuse in the vehicle's USB port. Below are the causes of USB unresponsiveness and precautions for using USB ports: Causes of USB unresponsiveness: Blown fuse in the vehicle's USB port. If there is a fuse blowout, promptly replace it with a spare fuse. Damaged data cable. Loose spring in the phone charging port, leading to poor contact. Precautions for using USB ports: Charging must only be done when the vehicle's engine is running to avoid damage to electrical devices caused by unstable power supply. Do not charge too many devices simultaneously to prevent overloading and damaging the car battery and alternator. Avoid using during thunderstorms to prevent lightning strike accidents. Do not use USB ports in humid environments. Rust or water stains may cause the USB drive to fail to connect properly.

How to Repair Small Dents Caused by Hail on a Car?

The following are detailed methods for repairing small dents: 1. Repairing dents on single-layer body metal panels: Use a wooden or plastic hammer to gently tap from behind the dent, while placing a suitable wooden block against the outer side of the metal panel to prevent the hammer's impact from bending the surrounding area. 2. Repairing dents on laminated metal panels: The drilling method is suitable for small dents, causing minimal damage to the sheet metal and paint. Drill a row of small holes in the dented or folded area using a hand drill, with the hole diameter and spacing determined by the condition of the outer panel deformation. The pull-ring method is suitable for larger damage areas, reducing harm from excessive perforations to the sheet metal. Insert into the small holes and pull them outward one by one until fully restored. During pulling, hold two pull rods in each hand, applying even and consistent force, pulling slowly without excessive effort. After leveling, weld the holes shut using carbon dioxide gas shielded welding.
