Adding a rear spoiler to a car is legal. The following vehicle modifications are not considered illegal: 1. Rear spoiler modification: When modifying a rear spoiler, the car owner must file a record with the vehicle management office in advance. After the modification is completed, the vehicle must be photographed again to update the photo on the vehicle registration certificate. 2. Vehicle body color: The body color can be changed, but within 10 days, the owner must go to the vehicle management office to take new photos and apply for a change of registration. Some color schemes used by law enforcement vehicles are not allowed to be modified. 3. Partial repainting: If the change in body color is within 30% of the total area, there is no need to go to the vehicle management office to change the registration or update the vehicle registration certificate. Additionally, wheels can be modified, but the size must remain the same as the original vehicle. The color or appearance can be changed freely, and there is no need to register the changes.

I've been researching car modifications for a while and noticed many people asking about the legality of installing rear wings. In China, this indeed requires caution. According to traffic regulations like the Road Traffic Safety Law, any modifications altering a vehicle's appearance or safety structure may violate rules - rear wings fall precisely into this category. Big cities enforce strictly while smaller areas are more lenient, but the principle remains: you must get approval from the vehicle management office before driving modified cars. Without declaration, if caught by traffic police, penalties range from fines and demerit points to mandatory removal and vehicle impoundment. Annual inspections pose another hurdle - unregistered wing modifications will certainly fail, forcing you to spend money reinstalling original parts. Insurance complications may arise too, as companies might deny claims for accidents involving unauthorized modifications. Don't assume small wings are safe either - oversized wings or those protruding beyond the car's original silhouette are more likely to be deemed illegal. My advice: if determined to install, first check local regulations online or consult the vehicle management office directly. Don't take risks. Safety comes first - modifications should improve your car, not trade style for potential hazards.

What are the symptoms of a faulty vacuum booster?

Automotive vacuum booster pump failure symptoms: It can cause heavy steering and abnormal steering noise. The larger the steering angle at low speeds, the louder the noise. Worn metal particles from the booster pump can damage the steering gear, and cleaning the pipelines is also troublesome, potentially requiring replacement. Additional information: 1. Definition of booster pump: An automotive booster pump refers to a component that helps improve and stabilize vehicle performance. It mainly assists the driver in adjusting the car's direction. Currently, most vehicles are equipped with booster pumps, primarily including steering booster pumps and brake vacuum booster pumps. 2. Classification of booster pumps: In the current market, power steering systems can be roughly divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. In mechanical hydraulic power steering systems, the amount of assistance is only related to the increment in steering wheel angle (angular velocity).

Why won't my Land Cruiser start with one-button ignition?

The reasons why a Land Cruiser won't start with one-button ignition are steering wheel lock or battery failure. Below are specific explanations: 1. Steering wheel lock: This is a simple anti-theft feature. When the engine is turned off, rotating the steering wheel from its centered position to a certain angle will trigger a "click" sound indicating the steering wheel is locked. The one-button ignition won't function when the steering wheel is locked. Solution: Turn the steering wheel left and right while pressing the engine start button to release tension and unlock the steering wheel. 2. Battery failure: Typically, a 60Ah battery supplies power to the radio at 12V voltage with about 10 watts of power. Including standby power from other devices, the total vehicle power consumption shouldn't exceed 30 watts. Theoretically, the radio could run continuously for 24 hours. Solution: If the battery is dead, use another battery to jump-start the vehicle or employ the manual push-start method. Failure to start may be caused by power drainage from leaving headlights on for extended periods or battery lifespan expiration. Generally, replace the battery promptly according to the maintenance manual.

What are the Four Heavenly Kings of Japanese Cars?

The Four Heavenly Kings of Japanese cars are as follows: 1. The King of Naturally Aspirated Engines - NSX: Honda stubbornly used a 3.2-liter naturally aspirated engine instead of a TURBO engine, and it's hard to find any resemblance to a typical Japanese car, making it more like an Italian sports car. 2. The Undefeated Emperor - GTR: GTR is highly popular in the tuning circles of any country, not only because the RB26 engine can be modified to exceed a thousand horsepower, but also because enthusiasts adore its unique four-wheel-drive system. 3. The Straight-line Dominator - SUPRA: The SUPRA, equipped with twin TURBOs, is unrivaled in straight-line acceleration. A heavily modified SUPRA can reach 900 horsepower, and even the undefeated GTR can't gain any advantage in a 0-400 straight-line race. 4. The Rotary Prince - RX-7: Mazda has always believed that the rotary engine is the best in the world. Although, in terms of factory specifications, the RX-7's torque and horsepower are slightly inferior to the other three kings, considering its mere 1.3-liter displacement, such performance is enough to prove the power of the rotary engine.

What is the difference between repainting and original factory paint?

Repainting is not as good as the original factory paint, as it is prone to fading and chipping, and partial area touch-ups may have color differences. Original factory automotive paint is typically baked paint. In automobile manufacturing plants, after the frame and body shell are welded, the next step is painting. The types include standard paint, metallic paint, and pearl paint. The process of repainting a car involves applying putty, sanding, and painting. Below is relevant information about automotive paint: 1. Overview: Automotive paint is a protective film applied to cars, a type of coating that makes the body less susceptible to corrosion and enhances aesthetic appeal. Different automotive paints produce different effects, and the quality of the paint itself, along with the technology and a good painting environment, is crucial. Most car owners invest more effort into beautifying their vehicles, as it is a way to express individuality. 2. Advantages: The paint film has excellent fullness, high gloss, high hardness, and strong adhesion. It possesses superior mechanical properties, outstanding gloss retention, weather resistance, and abrasion resistance, as well as good resistance to acids, alkalis, alcohol, and gasoline.

Why does the car air conditioner suddenly stop cooling and only blow air?

Reasons and solutions for a car air conditioner blowing air but not cooling are as follows: 1. Lack of refrigerant: Insufficient refrigerant in the air conditioning system leads to reduced pressure and less heat being carried away, giving the impression that the air conditioner is only blowing air. To check, observe the sight glass on the dryer tank. During normal operation, if there are continuous slow bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble turbulence is seen, it means the refrigerant is severely lacking. The solution is to replenish the refrigerant. Note: If adding from the low-pressure side, do not invert the refrigerant bottle; if adding from the high-pressure side, do not start the engine. 2. Too much refrigerant can also cause the air conditioner to stop cooling: The proportion of refrigerant in the system must meet certain requirements. Excess refrigerant can affect heat dissipation, as can adding too much cooling oil during maintenance. Solution: Observe the sight glass on the dryer tank. If no bubbles are visible during operation and none appear after the compressor stops, the refrigerant is excessive. If the cooling oil is over-pressurized, turbid bubbles may be seen in the sight glass. If refrigerant is indeed excessive, slowly release some from the low-pressure side service port. 3. Loose compressor drive belt: A loose belt causes slippage, reducing transmission efficiency and compressor speed, which decreases refrigerant compression and delivery, leading to no cooling. If the belt is too loose, tighten it. If it cannot be turned by hand, it is too tight and should be loosened slightly. If tightening doesn’t work or the belt is cracked or aged, replace it. 4. Electrical issues: Many problems can cause the compressor to stop working, with electrical issues being common. A preliminary check can be done by directly powering the compressor’s electromagnetic clutch. Generally, compressors rarely fail directly.
