What Causes the Abnormal Noise When Turning the Steering Wheel to the Right?

Here are the specific reasons for abnormal noise when turning the steering wheel to the right: 1. Faulty airbag clock spring: If the noise comes from inside the steering wheel, it may be caused by interference from the airbag clock spring inside the steering wheel. 2. Lack of oil in the shock absorber top bearing: When turning the steering wheel, if the abnormal noise comes from outside the car, it may be due to lack of oil in the shock absorber's top bearing. 3. Loose stabilizer bar bushings: If the noise does not come from the shock absorber's top bearing, check whether the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings will not only cause noise when turning the steering wheel but also when driving on uneven roads. 4. Dirty power steering fluid: If the power steering fluid is too dirty, it will increase the pressure in the power steering system.

What Causes Squeaky Brakes in a New Car?

The reasons for squeaky brakes in a new car are as follows: 1. The newly replaced brake pads and brake discs require a break-in period, which usually takes about 500 kilometers to complete. The brake discs may have been worn unevenly by the old brake pads, while the new brake pads have a smooth surface. Therefore, the contact area is initially small and requires break-in. It is normal to hear sounds before the break-in is complete. 2. Noise caused by brake pad material: Harder brake pad materials are more likely to produce such noises, while softer materials may result in sharper sounds. If this is accompanied by reduced braking effectiveness, this is likely the cause. 3. Improper installation of the braking system can also cause noise, which is more complex and requires inspection and handling at a repair shop.

When to Use Sport Mode?

Introduction to the usage scenarios of Sport Mode: It can be used during overtaking, uphill driving, or aggressive driving. The Sport Mode in a car should be used regularly and appropriately, as it helps remove carbon deposits inside the engine, improves fuel economy, and extends the engine's lifespan. Below are the relevant details: 1. After activating Sport Mode, the electronic control unit will increase the engine speed, ensuring the vehicle maintains sufficient torque for quick acceleration and deceleration. At this time, the car's performance can be fully demonstrated, and the previously unexperienced sense of acceleration (pushing force) will follow. 2. In addition, the car will adjust other settings, such as stiffening the suspension, increasing support force, enhancing throttle sensitivity, and increasing engine air intake, while fuel consumption will also rise. Some models may also directly alter electronic systems and body configurations, such as turning off the vehicle stability system and adjusting the spoiler.

Do You Need to Wait for the Engine Coolant Temperature to Rise Before Turning on the AC in Summer?

You do not need to wait for the engine coolant temperature to rise before turning on the AC in summer. Below are the specific reasons for low engine coolant temperature: 1. Thermostat malfunction: If the valve fails to close, the coolant will continuously circulate in the large loop, which may result in low engine coolant temperature. Alternatively, some vehicles may have their thermostats removed during summer to lower the temperature when it gets too high, leading to low engine coolant temperature. In such cases, the thermostat needs to be inspected and possibly replaced. 2. Constant operation of the cooling fan: For electric fans, circuit malfunctions can cause the fan to run continuously. Similarly, a faulty silicone oil clutch can also lead to constant fan operation. These issues can both cause low engine coolant temperature.

What should you do when turning in a manual transmission car?

Manual transmission turning operation steps: 1. First, pay attention to observing road signs and slow down early. At road and traffic intersections, there will be overhead road guidance signs on one side of the road. When turning, you must follow the road prompts and slow down as early as possible. 2. Pay attention to choosing the correct lane to enter the turning position according to the signs. Never change driving direction temporarily, and do not change driving route after entering solid lines. 3. When turning, pay attention to observing the road ahead while also taking into account blind spots on both sides, so as to have a clear idea. 4. If the speed is fast, you can press the clutch, apply slight braking, adjust the gear to a low gear, use inertia to drive slowly, and when the speed drops to a suitable gear speed, release the clutch pedal and drive at normal speed.

What Does the Semicircular Mark Mean?

The semicircular mark is a distance confirmation line. Related introduction: 1. Description: White parallel thick solid lines, used to provide drivers with a reference for maintaining a safe driving distance, used in conjunction with distance confirmation signs. They are installed in sections where overtaking frequently occurs, accidents are prone to happen, or other necessary areas. The function of the highway distance confirmation marking is to remind drivers to maintain a safe distance from the vehicle in front when seeing this marking, to avoid traffic accidents. 2. Extension: The white zigzag distance confirmation line has a total width of 300cm, with line widths of 40cm or 45cm. Starting from the confirmation base point at 0m, one line is set every 5 meters, with two lines forming a group, spaced 50m apart, repeated in five groups. Multiple groups can also be set up on-site as needed.
