Why does the brake pad make a loud noise when it gets wet?

Where is the spark plug located in a sedan?

The spark plug in a sedan is located at the top of the engine cylinder. Types of spark plugs: 1. Standard spark plug: The insulator skirt is slightly recessed into the shell end face, and the side electrode is outside the shell end face; 2. Extended insulator spark plug: The insulator skirt is longer and protrudes beyond the shell end face; 3. Fine electrode spark plug: Its electrodes are very thin, characterized by strong sparks and good ignition capability, ensuring quick and reliable engine start even in cold seasons, with a wide heat range suitable for various uses; 4. Tapered seat spark plug: Its shell and threaded part are conical, so it can maintain good sealing without a gasket; 5. Multi-electrode spark plug: Generally has two or more side electrodes, with the advantage of reliable ignition and no need for frequent gap adjustment; 6. Surface gap spark plug: Also known as the surface gap type, the gap between the center electrode and the shell end face is concentric.

What is the Curb Weight of a Car?

The curb weight of a car is introduced as follows:1. The curb weight of a car is also known as "unladen weight": This is an important design indicator for a car, which should be both advanced and practical. It is closely related to the design level, manufacturing level, and industrialization level of the car.2. The curb weight of a car: refers to the weight of the car when it is fully equipped according to the factory technical conditions (such as spare tires, tools, etc.), with all fluids filled.3. Under the same model conditions: the more reasonable the design method, the better the production level, and the higher the industrialization level, the lower the curb weight will be.

How to Shift to Neutral Gear While Driving an Automatic Transmission Vehicle?

Automatic transmission vehicles should not be shifted into neutral gear while driving. Here are the details about automatic transmission vehicles: 1. Automatic Transmission: It is possible to shift from D (Drive) to N (Neutral) while the vehicle is moving, but doing so can damage the automatic transmission. 2. When the vehicle is driving at high speed: Both the engine speed and the output shaft speed of the automatic transmission will be very high. Once the gear is shifted to N (Neutral), the connection between the engine and the wheels will be lost, and the hydraulic lines inside the automatic transmission will experience insufficient oil pressure, preventing normal lubrication of the transmission. This leads to an increase in the internal operating temperature of the transmission and greater friction pressure. 3. It can also damage the friction plates inside the transmission: The internal components of the transmission will age prematurely, and in severe cases, the transmission may be completely damaged.

How to Schedule the Subject 4 Driving Test?

The process for scheduling the Subject 4 test is as follows: 1. Open the Comprehensive Traffic Safety Service Management Platform: Select your province and city. 2. Choose the test scheduling option. 3. Click on "Register Now." 4. Fill in user information: Enter your ID number and the mobile phone number registered during your application (Note: If your phone number has changed, please update it directly at the vehicle management office service hall). 5. Select user type: Choose "First-time applicant for a motor vehicle driver's license." 6. SMS verification. 7. Service instructions: Read and agree, then click "Next." 8. Confirm information: Verify the information is correct and click "Next." 9. Test scheduling: Select the subject to schedule, the test location, the start and end time for the scheduling request, enter the image verification code, and click "Next." 10. Choose date and session: The system offers two scheduling modes—either selecting test sessions independently or allowing the system to arrange the test. If you choose the independent selection mode, the system will display all available test sessions within your selected time frame, allowing you to choose one or multiple sessions. If you opt for the system-arranged mode, the system will automatically match suitable test sessions within your selected time frame. After making your selection, click "Next" to confirm and submit. 11. Confirm submission: Review the information once more and click "Complete" if everything is correct. 12. Completion: Upon successful submission, the system will generate a service serial number. The system will arrange the test on the scheduled result announcement date and publish the scheduling results.

What to Do If the Driving License Training Time Card Is Lost?

If the driving license training time card is lost, it needs to be reissued by the relevant department. The following are the precautions for reissuing a driving license: 1. If the reissuance is successful but the new license has not been received, the original license cannot be used to drive a motor vehicle: If the driving license reissuance application is accepted, but due to time constraints, the new license is not received on the same day, driving is not allowed during this "gap period" until the new license is obtained. Otherwise, it will be considered as driving without a license. 2. After obtaining a new license, the original driving license becomes invalid: If the driving license is lost and a new one is reissued, even if the original license is found later, it will be considered invalid, and the new license should be used as the valid document.

How to Check the Water Temperature Gauge on a BMW 5 Series?

You can directly view it through the water temperature sensor or indirectly judge it via the oil temperature gauge. More relevant information is as follows: 1. The BMW 5 Series produced by Brilliance does not have a water temperature gauge; it will only issue an alarm when the water temperature is too high. However, it is equipped with a water temperature sensor, and the small LCD display hides the water temperature reading. If you don't know how to read it, you can also infer the water temperature from the oil temperature. Many cars have a water temperature gauge on the dashboard to display the real-time water temperature condition of the car, allowing the driver to determine if the engine is functioning normally based on the water temperature reading. However, a few cars, such as the aforementioned BMW 5 Series, do not have an obvious water temperature gauge, making it quite troublesome to determine the water temperature. 2. Generally, the oil temperature is 15-20 degrees higher than the water temperature. Normal oil temperature ranges between 115-125 degrees, so the water temperature would be between 100-105 degrees. Additionally, even though the vehicle lacks a water temperature gauge, it will still issue a warning if the water temperature is too high, so owners need not worry excessively about the absence of a water temperature gauge. If a warning is issued due to excessively high water temperature, it might be due to insufficient coolant, a malfunctioning cooling system, or a faulty circulation water pump. The water temperature gauge reflects the condition of the engine, and any faults should be promptly addressed and repaired.
