To remove air from the Wuling Hongguang radiator, it needs to be bled through the small overflow tank's thin tube. The specific operation steps are as follows: 1. Press the brake pedal of the Wuling Hongguang. 2. Turn the car key to start the engine. 3. Wait until the dashboard lights up and run the engine until it reaches 90 degrees Celsius. 4. Turn off the engine and let it cool down to room temperature. 5. Open the front hood. 6. Slowly unscrew the cap of the small overflow tank to release the high-pressure gas inside the radiator. 7. Top up the coolant, making sure to fill it only up to the MAX mark.

I remember the first time I bled the radiator of my Wuling Hongguang was after a long trip when the engine temperature ran a bit high, so I decided to do it myself. The usual steps are quite simple: First, let the car sit and cool for at least half an hour—don’t touch any hot components to avoid burns. Then, pop the hood and locate the radiator filler cap, loosening it gently with a small wrench. Next, start the engine and let it idle for a few minutes while monitoring the coolant level. If the level drops or bubbles appear, slowly top it up with coolant (preferably the OEM antifreeze) until the bubbles diminish and disappear. Keep the AC or fans off during the process and stay patient—it usually takes about 5–10 minutes. After bleeding, the engine temperature returned to normal, and I’ve maintained it this way ever since to prevent overheating damage. The key is ensuring the system is sealed and checking hoses for aging, as air can re-enter otherwise.

Can You Make a U-Turn at an Intersection?

Whether a vehicle can make a U-turn at an intersection depends on the specific road conditions. Below are the situations where a U-turn is permitted at an intersection. Lanes with U-turn signs: When the U-turn signal light is green, you can make a U-turn while ensuring your own safety. Intersections without U-turn signs but allowing left turns: At intersections where left turns are permitted and there are no signs or markings prohibiting U-turns, you can also make a U-turn. However, the U-turn should not affect the normal flow of other vehicles, and you must follow the left-turn lane signal light. Yellow grid line areas: Although yellow grids are no-stopping zones, as long as there is no central barrier, you can make a U-turn after yielding to normally moving vehicles. Areas with dashed lines on the green belt: Vehicles on the side where the dashed lines are located can make a U-turn there. Note that U-turns in this situation are not controlled by traffic signals, but you must yield to vehicles moving straight. If making a U-turn does not require crossing the lane stop line, you do not need to consider the traffic light and can make a reasonable U-turn. However, if making a U-turn requires crossing the stop line of the left-turn or U-turn lane, you must observe the traffic light. Do not cross the stop line when the light is red.

What is the Problem with Rusty Brake Pads?

Rusty brake pads are a normal occurrence, primarily caused by the material of the brake pads, but this does not affect the safety or normal operation of the vehicle and does not cause any issues. If the rust on the brake disc is minimal, it does not require special treatment; if the rust is more severe, it may cause vibrations or shaking during braking, such as brake pad vibration, steering wheel shaking, or body vibration. In such cases, the brake pads need to be replaced. Most car brake pads are made of cast iron. Long-term exposure to rain, snow, and harsh environments inevitably leads to surface rust. If the rust is minor, it can be worn away through regular braking. Additionally, friction between the brake pads and the brake disc can also remove rust after several braking cycles, restoring normal use. If the brake pads are severely rusted, the surface becomes uneven, causing shaking, increased wear, or scratches, which can affect the vehicle's braking performance and driving safety. In such cases, it is best to take the vehicle to a repair shop. The brake disc should be removed, and the rust should be cleaned off with sandpaper. After proper installation, a road test should be conducted to ensure there are no abnormalities in braking. It is important to note that sanding should not be too forceful or done too frequently, as this can thin the brake disc, affecting its performance and lifespan.

What is the Difference Between Powder Coating and Baking Paint?

The differences between baking paint and powder coating include: powder coating has poorer gloss and roughness compared to baking paint; powder coating is generally thicker than baking paint; it offers better adhesion and corrosion resistance than baking paint; powder coating requires higher curing temperatures and typically uses electrostatic application, while baking paint generally requires lower temperatures; surface treatment for powder coating can be simpler, not requiring a primer, whereas baking paint needs a primer during application. Baking paint is an industrial paint, divided into two types: water-based metal paint and oil-based metal paint. Water-based metal paint is an environmentally friendly coating using water as a solvent, while oil-based metal paint uses organic solvents. The method involves roughening the material slightly and then applying some paint. Baking paint is non-sticky, making the coating less likely to adhere to other substances, while the film exhibits good bonding properties. Additionally, baking paint is heat-resistant and has low friction. It offers excellent wear resistance under high loads, combining the dual advantages of wear resistance and non-adhesion under certain loads. Baking paint is resistant to chemical erosion, protecting components from any kind of chemical corrosion. Powder coating does not require thinners, making the process environmentally friendly and non-toxic to humans. The coating appearance is excellent, with strong adhesion and mechanical strength. The spraying process is shorter, and the coating's wear resistance is significantly higher, not requiring a primer. Some construction sites explicitly require the use of electrostatic spraying, which avoids the common flow issues seen in conventional spraying processes.

How Many Kilometers Can One Liter of 92 Gasoline Drive?

One liter of 92 gasoline can drive 10 kilometers to 15 kilometers. If driving on general city roads, the fuel consumption is approximately 8 liters per 100 kilometers, meaning one liter of gasoline can drive about 12.5 kilometers. Additionally, this depends on the vehicle condition, road conditions, and the driver's habits. Under normal circumstances, one liter of gasoline can support a 1.6L sedan to drive 10 kilometers to 15 kilometers. Theoretically, the heat contained in one liter of gasoline, divided by overcoming the friction and air resistance of a 1.4-ton car, can drive over 50 kilometers. In reality, the efficiency of internal combustion engines is generally around 35%. Friction in the car's transmission mechanism consumes 20%, while active engine cooling, exhaust heat dissipation, noise and vibration, and emission noise waste another 10%. A comprehensive gasoline utilization rate of about 22% is already quite energy-efficient. Therefore, during steady-speed cruising, one liter of gasoline can only drive 10-15 kilometers, which is related to factors like speed and driving habits. It is generally recommended to use 92 gasoline for engines with a compression ratio below 8.5. For engines with a compression ratio between 8.5-9.5, either 92 or 95 gasoline can be used. For cars with an engine compression ratio above 9.5, 95 gasoline or higher-grade 98 gasoline should be chosen to ensure the combustion environment inside the cylinder matches the engine's requirements.
