Is It Normal for Car Wheels to Rust?

Rust on car wheel hubs is not normal. The wheel hub is the central part of the wheel where the axle is installed, also referred to as the "rim" or "steel rim." Wheel hubs are prone to accumulating dirt, and if not cleaned for a long time, they can corrode and deform, leading to potential safety hazards. Methods to Remove Rust from Car Wheel Hubs: If the rust on the wheel hub is not severe, you can first use very fine water sandpaper dipped in water to gently sand away the rust spots. After completely wiping it clean, apply a layer of primer to ensure the rust does not spread or worsen. For new scratches, wipe them clean and directly apply primer. Most vehicles come with a small can of original paint. Methods to Prevent Rust on Car Wheel Hubs: Paint surfaces often rust due to frequent collisions and scratches. Additionally, small stones kicked up by tires while driving can chip the paint, leading to small rust spots over time. These minor damages are easily overlooked because they are often not very noticeable. Therefore, it is important to regularly maintain the body, hood, and outer areas of the car. If any rust is found, it should be addressed immediately by a professional auto detailing shop. While driving, it is inevitable to encounter rainy or snowy weather or pass through muddy and stagnant roads. Sludge can accumulate in small gaps under the car and on the floor. Hence, it is necessary to frequently check the inner and outer edges of the wheel hubs, the bottom corners of doors and the trunk, the keyholes of doors, and the moving parts of the wiper frame. Additionally, ensure that the drainage holes in doors and other parts of the body remain unobstructed. Monitor the humidity of interior coverings, such as carpets, to prevent rust in floor areas.

What Kind of Car is Considered a Stock Car?

Normally, cars that have been in stock for more than six months are referred to as stock cars. Here is an introduction to stock cars: 1. Imported Stock Cars: Parallel imported cars take up to 3 months to arrive at the port from the time they leave the factory abroad, depending on the location of the foreign factory, such as the USA, Canada, Europe, or the Middle East. However, delays in customs clearance at the port can prolong this period. Therefore, imported models that have been manufactured more than 6 months ago are considered stock cars. 2. How to Identify a Stock Car: The manufacturing date marked on the nameplate in the engine compartment indicates the actual time the car has been in stock. Imported cars that have been in stock for more than 6 months can be classified as stock cars. Additionally, if there are obvious signs of aging on parts such as the wipers, engine belts, or tires of an imported car, it can also be considered a stock car. Finally, you can check the battery by trying to turn on high-power-consuming devices like the high beams for about 10 minutes with the engine off. If the battery cannot sustain this, it is likely a stock car.

What Does the Exclamation Mark on the Car Dashboard Mean?

There are five situations when an exclamation mark appears on the car dashboard, namely general fault, automatic transmission fault, brake system fault, abnormal tire pressure, and lighting fault. The following is a detailed analysis of the five situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the general performance or components and functions of the car. 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 find out the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Brake System Fault: An exclamation mark in the middle of a circle with brackets. This represents the warning of the brake system, mainly including brake system failure and low brake fluid level. The brake system needs to be inspected immediately to avoid accidents. Abnormal Tire Pressure: An exclamation mark in the middle of a horizontal line below brackets. This represents the tire pressure monitoring warning light. When the tire pressure of the car is too low, this warning light will light up. It is necessary to check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating that there is a fault in the car lights. 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 is.

What is a runaway truck ramp?

A runaway truck ramp is typically set up on long downhill sections of highways to prevent vehicles from losing control, consisting of a steep slope. Below is relevant information about runaway truck ramps: 1. Entrance and exit ramps: These are auxiliary connecting sections for entering and exiting the main roadway, which can be "at-grade ramps" or "interchange ramps." They are major traffic infrastructure components of road interchanges. 2. On-ramps and off-ramps: These are auxiliary inclined connecting sections for ascending or descending elevated roads, usually "interchange ramps." Note: Both of the above (items 1 and 2) often incorporate the design of collector-distributor roads. 3. Direct ramp: Positions the right-turn lane on the right side. 4. Indirect ramp: Positions the left-turn lane on the right side, using a loop to connect to other highways. 5. Semi-direct ramp: Similar to an indirect ramp but without a loop, instead using a longer and more undulating elevated road as the connecting ramp.

What does the EPC light on the dashboard mean?

The EPC indicator light can illuminate in two scenarios: during the power-on self-test and under other conditions. The power-on self-test is a pre-driving check of all vehicle sensors. Typically, if the vehicle is not started after power-on, the light will turn off by itself after about 3 seconds. If the EPC light remains on after starting the vehicle or illuminates under other circumstances, the common causes include faults in the engine intake system, throttle, fuel system, engine, ECU control unit, or brake lights. Here is a detailed explanation of the reasons for the EPC light illuminating under other conditions: Engine intake system fault: The EPC light will illuminate if the engine intake is obstructed or insufficient. Throttle fault: Carbon buildup is a common issue with the throttle. Additionally, dirt accumulation can affect intake, triggering the indicator light. Fuel system fault: Issues such as substandard fuel, fuel degradation, or poor fuel atomization can cause the light to come on. Engine fault: Insufficient engine pressure or problems with components like the intake valve can also trigger the EPC light. ECU control unit fault: Interference with the vehicle computer signals or false alarms from the computer may cause the light to illuminate. Brake light fault: If the brake lights fail to turn on, the brake switch malfunctions, or there are issues with the brake wiring. Solutions for the EPC light illumination: Troubleshoot the intake system, use fuel with the appropriate octane rating, and clean the throttle. Remove carbon deposits from relevant components. Re-flash the ECU with updated data. If the EPC light comes on, the driver can first try turning off the engine and restarting it to see if the light remains illuminated. If it does not, the issue may have been temporary. However, if the light stays on or frequently illuminates, it is advisable to drive to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data is abnormal, the EPC system takes predefined actions to manage the powertrain. The EPC indicator light typically appears in two colors: yellow and red. A yellow EPC light indicates a fault, but the vehicle can still be driven cautiously to a repair shop. A red EPC light signifies a severe issue, requiring immediate stopping of the vehicle and contacting a professional for repairs. Continuing to drive with a red light may damage core components or compromise safety.
