How to deal with a small piece of missing car paint?

Here are the methods to deal with a small piece of missing car paint: 1. Professional repair: If the car is only slightly scratched and the scratch is not deep, just the surface paint is damaged, you can repair the scratched paint by waxing. Professional auto maintenance shops outside can provide full-car waxing for about 200 yuan. 2. Sheet metal repair: If the scratch has damaged the car's primer or even caused sheet metal deformation, you need to grind off the paint, perform sheet metal repair, and then repaint with various layers of paint. If not treated in time, the area with missing paint may develop rust.

What are the pros and cons of powering a dash cam from the fuse box?

The advantages and disadvantages of connecting a dash cam to the fuse box are as follows: 1. Advantages: It allows for concealed wiring, providing better stealth and enhanced safety, and does not occupy the cigarette lighter port. Additionally, using a step-down cable to connect to the fuse box's constant power ensures that the dash cam remains in standby mode after the vehicle is turned off, enabling parking surveillance. Extra protection is provided by the fuse, enhancing safety. Installing a power delay switch (with adjustable timing) can prevent power surges to the dash cam during ignition. 2. Disadvantages: If the dash cam lacks a low-voltage protection feature, it can easily lead to battery drain. Moreover, wiring from the fuse box is slightly more complicated.

What is the concept of ignition advance angle?

Ignition advance angle refers to the crankshaft angle at which the engine ignites before the piston reaches the top dead center of compression. Here is its introduction: 1. Function: There is a time process for the mixture to ignite, burn, and finish burning. The role of the optimal ignition advance angle is to ensure that the maximum gas expansion phase occurs during the piston's downward power stroke under various operating conditions. This results in the highest efficiency, minimal vibration, and the lowest temperature rise. 2. Influencing factors: The most significant factor affecting the ignition advance is the engine speed. As the speed increases, the time to rotate through the same angle becomes shorter, requiring a larger advance angle to achieve the corresponding advance time.

Should You Sell or Continue Driving a Car After Water Immersion?

After a car has been immersed in water, it is generally advisable to sell it, as the engine may sustain damage from water exposure. Relevant information regarding water immersion in vehicles is as follows: 1. Engine Damage: There are primarily two scenarios where engine damage occurs due to water immersion: prolonged soaking of the vehicle in water and attempting to restart the engine while submerged. 2. Auto Damage Insurance: Owners can only receive insurance compensation for water immersion if they have purchased "auto damage insurance." However, this mainly covers losses such as damage to seats and wiring caused by water immersion. Damage to the engine from driving through water or starting the engine while submerged is typically not covered by insurance.

What does the yellow exclamation mark in Wuling Hongguang Mini mean?

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general fault, automatic transmission fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside indicates that the car's general performance or components and functions have malfunctioned. This mainly includes parking sensor failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricant is below the normal range. The transmission oil needs to be replaced in time. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will come on. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator light, indicating that a car light has malfunctioned. Solution: Go to a 4S shop for inspection and treatment as soon as possible, or you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to see where the problem lies. There is also a red exclamation mark with a bracket and a circle in the middle, which represents a warning of the braking system, mainly including brake system failure and low brake fluid level. The braking system needs to be inspected and repaired immediately to avoid accidents.

Does the Bestune T99 come with a built-in dash cam?

Bestune T99 does not come with a standard dash cam, and it needs to be installed as an optional accessory. Functions of a dash cam: A dash cam is a device that records images, sounds, and other related information during vehicle travel. After installation, it can record the entire driving process in video and audio, providing evidence for traffic accidents. Considerations when purchasing: A dash cam should have good camera clarity and night shooting capability. High definition is determined by the main control chip of the dash cam, so car owners need to pay attention to the image processing solution of the main control chip. Additionally, the dash cam should have sufficient storage space to enable long-term effective recording.
