For small dents on the hood, you can purchase a car dent repair tool online to suck them out yourself. For larger dents, it is necessary to drive the car to a repair shop or a 4S store and have professionals perform sheet metal repairs. The functions of the hood are as follows: 1. Airflow guidance. For objects moving at high speed in the air, the air resistance and turbulence generated by the airflow around the moving object directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the car. Through guidance, air resistance can be decomposed into beneficial forces, increasing the force of the front wheels on the ground, which is beneficial for the car's driving stability. The streamlined appearance of the hood is basically designed based on this principle. 2. Protection of the engine and surrounding pipeline accessories. Under the hood are important components of the car, including the engine, electrical circuits, oil circuits, braking system, and transmission system, etc., which are crucial to the vehicle. By improving the strength and structure of the hood, adverse effects such as impact, corrosion, rain, and electrical interference can be fully prevented, ensuring the normal operation of the vehicle. 3. Aesthetics. The exterior design of a vehicle is a visual representation of its value. As an important part of the overall appearance, the hood plays a crucial role in being pleasing to the eye and reflecting the concept of the entire car.

Should coolant be topped up or completely drained and refilled when low?

When the coolant level is low, you can either top it up or completely drain and refill it. The steps for replacing coolant are as follows: 1. Open the vehicle's engine hood, and you can see the coolant reservoir in the upper right corner; 2. Open the coolant drain plug under the radiator to drain the old coolant; add new coolant, tighten the cap, and the coolant replacement is complete. 3. Additional information: The full name of coolant should be antifreeze coolant, meaning it is a cooling liquid with antifreeze properties; coolant prevents the cooling liquid from freezing during cold winter parking, which could cause the radiator to crack or damage the engine cylinder block or head due to expansion.

Do I Need to Press the Brake When Shifting from D to L in an Automatic Transmission?

When shifting from D (Drive) to L (Low) in an automatic transmission car while driving, you do not need to press the brake. There is a dedicated button on the gear lever or shift handle specifically for shifting in this situation—simply press and hold the button to complete the operation. More details are as follows: 1. Automatic Transmission Gear Positions: In an automatic transmission, P stands for Park, R for Reverse, N for Neutral, S for Sport mode, D for Drive, L for Low gear, and M for Manual mode. 2. Shifting on Slopes: When going downhill or on long slopes, shift to L gear to restrict the car to the lowest gear automatically. This allows the car to use engine braking when descending, preventing the driver from having to press the brakes for extended periods, which could overheat the brake pads and lead to danger.

How to distinguish between National IV and National V?

Methods to distinguish between National IV and National V are as follows: 1. Check the fuel consumption label on the car; 2. Look at the vehicle's nameplate, find the combination of numbers and letters in the vehicle model, locate the engine model, then log in to the Motor Vehicle Environmental Protection Website, input the vehicle model and engine model to query. 3. Extension: Compared to National IV, the National V standard reduces nitrogen oxide emissions by 25% for light vehicles and 43% for heavy vehicles; the biggest difference between National V and National IV is the stricter emission standards for heavy vehicles.

What are the main differences between domestic cars and joint venture cars?

Domestic cars and joint venture cars mainly differ in the following aspects: 1. Transmission: Many domestic brands prefer to directly purchase mature products from abroad, such as FAW, GAC, BYD, and Great Wall. Basically, domestic models, apart from CVT and dual-clutch transmissions, have no major issues with manual and AT transmissions. Among them, Chery performs well in CVT, while Geely excels in AT. 2. Engine: Mainstream domestic brands have their own flagship engines. Although there may be some technical gaps compared to joint venture brands, there are no major issues in terms of quality and stability. Some joint venture state-owned enterprises use engines from joint venture brands. For example, SAIC's Roewe and MG models use the SEG series engines co-developed by SAIC and General Motors.

What to Do If the Front Bumper Cracks?

The cracked front bumper can be repaired or replaced. The specific repair process for the bumper is as follows: 1. Preparation: Smooth out the entire bumper to facilitate the repair. Clean the dirt around the damaged area of the bumper to ensure the putty adheres firmly. Using a brush usually yields good results. If oil stains are found on the bumper, the putty may not adhere well, so it's best to use paint thinner to repair areas where the paint has peeled. 2. Repair: Prepare putty in various colors, preferably choosing one that closely matches the bumper's color. Mix the putty with the bumper, and once mixed, apply the putty with a spatula. After 2-3 hours, when the putty has hardened, sand it with around 1000-grit sandpaper. Wait for a week before repainting.

Is Ignition Advance Angle the Same as Ignition Timing?

Ignition advance angle and ignition timing are not the same. 1. Ignition advance angle: The angle through which the crankshaft turns from the moment of ignition until the piston reaches the top dead center of compression is called the ignition advance angle. 2. Ignition timing: It refers to igniting the combustible mixture in the cylinder at the precise moment to push the piston and generate power. Below are the steps to adjust the ignition advance angle of a vehicle: 1. Make a mark. 2. Warm up the engine until it reaches a stable idle state. 3. Loosen the fixed bolt of the timing. 4. Adjustment: Adjust the top part of the timing towards the rear of the vehicle to advance the ignition angle, and adjust it forward to delay the ignition angle. Adjust the timing slightly towards the rear of the vehicle, tighten the bolt, and test the vehicle. You can gradually adjust it until knocking occurs. Then, adjust the timing towards the front of the vehicle until the knocking disappears, tighten the fixed bolt, and the adjustment is complete.
