A door needs to be replaced when the dent diameter exceeds 10 centimeters, the bent or damaged area exceeds 30%, or the deformed part of the window frame reaches 20% of the frame body. If the rubber buckle of the door window regulator assembly is broken, the steel wire is scattered, the gear teeth are damaged, the lifting bracket is deformed by more than one-third, or the motor is damaged and cannot operate, it should be replaced in principle. After a door is dented, it needs to be dealt with promptly to avoid rust. The door provides access for the driver and passengers, isolates external interference, and to some extent mitigates side impacts to protect the occupants. The quality of a door is mainly reflected in its anti-collision performance, sealing performance, ease of opening and closing, and other functional indicators. Anti-collision performance is particularly important because, in the event of a side impact, the buffer distance is very short, making it easy to injure people inside the vehicle. If the door is dented but the paint is not damaged, you can try paintless dent repair technology to restore it. This method does not require damaging the original car paint for body dent repair. The principle is based on optics and mechanics, using the lever principle to restore dents of varying depths to their original factory condition. For metal parts on the car, do not overly obsess about whether they are original factory parts. If metal parts are damaged, it is recommended to replace them rather than attempting to preserve the original parts through panel beating, as this may prove to be more costly in the long run. Additionally, doors are divided into two types of structures: one-piece and split-type. Most car owners believe that one-piece doors have better safety performance because split-type doors are welded together, resulting in lower costs and inferior safety compared to one-piece doors. However, the cost difference between these two types of doors is not significant, and their safety performance is similar. The choice of door type depends on the car's design. Whether the insurance company's damage assessment process meets the standards of insurance appraisal institutions depends on the specific situation, but generally, they are consistent. The standard for vehicle damage assessment is determined based on the vehicle's price and the type of insurance coverage. If the insurance coverage is comprehensive, once an accident occurs, the insurance company will compensate for 100% of the vehicle's losses.

What is the difference between coolant and antifreeze?

The difference between engine antifreeze and coolant is that antifreeze only has antifreeze function, while coolant has both cooling and antifreeze functions. The full name of coolant is antifreeze coolant, which is a coolant with antifreeze function. Correct use of coolant can not only protect the engine's cooling system to improve heat dissipation, but also improve engine efficiency and extend its service life. The following are other functions of antifreeze coolant: 1. Anti-corrosion function: The engine and its cooling system are made of metals such as copper, iron, aluminum, steel, and solder. These metals will corrode and rust when exposed to water at high temperatures over time. Antifreeze coolant not only does not cause corrosion to the engine cooling system but also has anti-corrosion and rust removal functions. 2. High boiling point of antifreeze coolant: The boiling point of water is 100°C, while the boiling point of high-quality antifreeze coolant is usually above 110°C, making it less likely to boil during summer use. 3. Antifreeze coolant prevents scaling: The most troublesome issue for drivers using water as a coolant is scaling. Scale adheres to the metal surfaces of the radiator and water jacket, gradually reducing heat dissipation efficiency and being difficult to remove. High-quality coolant is made with distilled water and contains anti-scaling additives, which not only prevent scaling but also have descaling functions.

How to Shift Gears While Driving a Manual Transmission Car

Manual transmission car shifting methods while driving are as follows: 1. Upshifting: First increase the vehicle speed to the required shifting speed, then press the clutch - shift gear - release the clutch while pressing the accelerator. 2. Downshifting: First reduce the vehicle speed to the required shifting speed, then: press the clutch - shift gear - release the clutch while pressing the accelerator; remember that when downshifting, the vehicle speed must be reduced, otherwise the speed will be too high to shift gears. 3. While driving, you can reduce speed without shifting gears depending on the situation, use the brake to reduce speed without frequently using the clutch. When braking, except in emergency situations, do not stomp on the brake pedal, mainly use intermittent braking.

Reasons for No U-Turns at Railroad Crossings

Railroad crossings prohibit U-turns because they can easily cause accidents. Here is some information about illegal U-turns: 1. Making an illegal U-turn is a violation of traffic laws, specifically the prohibition signs, and will result in a fine and a deduction of 3 points from the driver's license. 2. Article 7 of the "Procedures for Handling Road Traffic Violations" states: Traffic police officers who discover minor violations that do not affect road traffic or safety should verbally inform the violator of their offense. 3. The "Implementation Regulations of the Road Traffic Safety Law" thus stipulates that "motor vehicles are prohibited from making U-turns at locations with no U-turn or no left-turn signs or markings."

How to Set Up the One-Touch Auto Window Roll-Up Function?

One-touch window roll-up setup: First, press the vehicle's one-touch start button to power on the vehicle. Then, continuously pull the one-touch window roll-up button located on the left door armrest. While holding the window roll-up button, press the button on the left multifunction steering wheel. After that, press the SET button on the right multifunction steering wheel to complete the one-touch window roll-up function setup. Below is relevant information about the one-touch window function: 1. How to use the one-touch window function: With conventional power windows, you need to hold the switch until the window reaches the desired position, then release the button to stop the movement. Cars equipped with one-touch windows have a two-stage window control switch. The first stage works like conventional power windows. The second stage allows the window to fully open or close automatically with just one press and release. 2. Purpose of the one-touch window design: Nowadays, most mid-to-high-end models come with the one-touch window function, primarily for the convenience of drivers and passengers. Its main purpose is to prevent drivers from being distracted while operating the windows, thereby improving safety. One-touch windows generally feature an 'anti-pinch' function to avoid the risk of pinching fingers.

What is the Difference Between Part-Time 4WD and Full-Time 4WD?

Part-time 4WD and full-time 4WD mainly differ in the following aspects: 1. Part-time 4WD is only used in some hardcore or professional off-road vehicles, with the drawback of causing more wear and tear on components compared to the other two types (on-demand 4WD and full-time 4WD) when driving on roads; the driver can manually operate the control lever to select low-range 4WD, high-range 4WD, low-range 2WD, high-range 2WD, etc.; 2. Full-time 4WD has the most complex structure and, as the name suggests, operates in four-wheel drive under all conditions, commonly found in performance vehicles; its drawbacks include higher fuel consumption and, generally speaking, less power than part-time 4WD.
