Is Replacing the Rear Panel a Serious Issue?

What Causes the Feeling of Scraping the Undercarriage When Braking?

The sensation of scraping the undercarriage when braking can be attributed to several reasons: worn brake pads, loose undercarriage components, aging rubber parts in the undercarriage, or issues with the lower control arm. Car owners can eliminate such abnormal noises by replacing brake pads, tightening undercarriage screws, or replacing rubber components. Additional information is as follows: 1. Braking: Refers to the action of stopping or reducing the speed of moving locomotives, vehicles, or other transportation tools or machinery. 2. Undercarriage: Refers to the combination of the transmission system, driving system, steering system, and braking system in a vehicle. It supports and installs the engine and its various components and assemblies, forming the overall shape of the vehicle, bearing the engine's power, and ensuring normal driving.

Can China 5 be upgraded to China 6?

Yes, upgrading components such as the three-way catalytic converter and engine ECU logic can indeed improve the vehicle's emission standards. Here is relevant information: 1. Reason: The emission standard of each vehicle is already recorded in the factory certificate upon production. Therefore, even if the China 6 standard is achieved through various methods, it does not mean the vehicle is officially recognized as a "China 6 vehicle". Additionally, since European emission standards are ahead of China's, many global models already meet the yet-to-be-announced China 6 standard. However, due to the domestic fuel quality not yet meeting the China 6 standard and only the China 5 standard being certifiable previously, these vehicles could only be classified as China 5 models. 2. China 6: The full name of the "China 6" emission standard is: National Sixth Stage Emission Standards for Light-duty Vehicles. It is an upgraded standard based on China's domestic conditions, revising the "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China Fifth Stage)".

What does the oil grade 0W20 mean?

The W in 0W20 oil grade stands for WINTER. The number before W represents the freezing point temperature. The number after W represents the kinematic viscosity of the oil at 100°C, and 20 indicates that the oil grade is the lowest level. Below is a detailed introduction about oil grades: 1. Overview: Oil grades include two parts: classification and viscosity specification. Oil grades usually indicate viscosity and quality. 2. Meaning: W stands for winter. The smaller the number before W, the better the low-temperature fluidity of the oil, indicating a lower usable environmental temperature and better protection for the engine during cold starts. The number after W is an indicator of the oil's high-temperature resistance. The larger the number, the better the oil's protective performance at high temperatures.

How to Clean Cement from a Car Thoroughly?

You can use an acidic solution for cleaning, such as common white vinegar. White vinegar is an acidic liquid that can effectively dissolve cement. Specific instructions are as follows: 1. Cement has certain corrosive properties: It is not good for the car paint and should be removed promptly. Before it hardens, you can use a towel with cleaning solution to wipe it off. If the cement is not detected and treated in time and has already solidified and hardened, an acidic solution will be needed for cleaning. 2. Besides white vinegar, you can also purchase cement cleaning agents for washing: The cleaning method is the same as with white vinegar. For small areas of cement, you may consider cleaning it yourself. For large areas, it is recommended to go to a professional car wash shop, as they have specialized cleaning agents and provide more professional cleaning services.

What is the Difference Between Coating and Waxing?

The main differences between coating and waxing can be summarized in three points. Below is a detailed introduction to the differences between coating and waxing: 1. Different Processes: Car wax is rarely applied after polishing, often without addressing surface imperfections. Before coating, polishing is required to remove shallow scratches and oxidation layers from the paint surface, restoring its original gloss and enhancing the mirror effect. Sometimes, infrared lamps are used to accelerate curing for better results. 2. Different Materials: Car wax mainly consists of polyethylene emulsion or silicone-based polymers, which are oxides. Coating materials are mostly silica-based, belonging to inorganic substances. Organic materials oxidize easily, while inorganic materials do not. 3. Different Effects: Car wax provides basic protection for the paint surface but is prone to water decomposition, has a short lifespan, and lacks abrasion resistance, typically lasting only about a month. Coating, on the other hand, is a paint maintenance treatment that offers high-temperature resistance, water resistance, friction resistance, reduced dust adhesion, acid rain protection, oxidation resistance, and UV resistance, generally lasting up to a year.

Can a Car with Modified Body Kit Pass the Annual Inspection?

If the modified body kit has been registered with the vehicle management office, it can pass the annual inspection. If not registered, it cannot pass the inspection. Changes to the vehicle's body color, model, performance, purpose, and structure, as well as replacement of the frame, body, or engine, all require applying for modification registration with the vehicle management office. Body kits are categorized into minor and major kits, and since they alter the car's appearance, they must be registered with the vehicle management office. Otherwise, the vehicle may be penalized by traffic police or fail the annual inspection. Vehicles with any of the following conditions must undergo the necessary procedures before being inspected: discrepancies between the vehicle's condition and the records in the driving license or archives; damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; modifications, model changes, or technical transformations without approval and modification procedures; failure to display the required unit name and enlarged license plate characters as specified; improper installation of alarms or indicator lights; or failure to pay road maintenance fees and insurance as required.
