How to Repair Welding Spots on Car Windshields?

Methods for repairing welding spots on car windshields are as follows: 1. Ordinary Glass: For glass burns, sandpaper can be used for grinding and polishing, but due to the depth of the damage, there will be noticeable indentations after treatment. Therefore, whether to proceed with the repair depends on the size and location of the damage. Typically, car owners can claim under glass insurance. 2. Tempered Glass: If it's tempered glass, it cannot be repaired. If it's not tempered, a glass polishing machine can be used for gradual grinding. Car glass is heated in a furnace to near the softening temperature and then quickly transferred to fans with varying cooling intensities for uneven cooling. This creates different stress levels between the main viewing area and the peripheral areas of the glass. The peripheral areas, positioned under the strong airflow of the cooling fans, undergo full tempering, resulting in better fragment characteristics in these areas.

What does car battery depletion mean?

Depletion usually refers to insufficient voltage (or power). When the battery power is insufficient and the internal resistance of the power source is too high, the electrical appliances cannot obtain the rated voltage required for normal operation. This low-voltage state is referred to as depletion. Additionally, if the car's generator charging system malfunctions and fails to replenish the battery power consumed during startup and other circuit operations in a timely manner, it can also lead to depletion. Symptoms of depletion: Difficulty starting the vehicle, dim lighting; Open-circuit voltage of the battery measures below 12V; Load test results fall in the red zone; Cold cranking amperage (CCA) value is significantly lower than the standard, requiring comparison with the parameters provided by the manufacturer. Possible causes: Corroded connections or aging wiring harnesses, leading to excessive voltage drop during startup; Prolonged storage or storage at high temperatures, especially for older batteries—summer conditions also require careful monitoring of battery status; Electrical appliance power exceeds the generator's output power; Excessive static leakage current in the vehicle. Correct handling methods: Different levels of depletion require different approaches. If the battery depletion is not severe, the owner only needs to adjust the charger output voltage between 13.8V-14.4V. For deeply depleted batteries, off-vehicle low-current supplemental charging is necessary. Regularly inspect the condition of wiring harness terminal connections, keeping them clean, dry, and securely connected. Develop good car usage habits and avoid excessive power consumption when the engine is not running.

What is the introduction of the automatic transmission gears for the 10th-generation Accord?

Here is the introduction of the automatic transmission gears for the 10th-generation Accord: 1. All gears: The automatic transmission gears include P, R, N, D, 2 or S, and L or 1. 2. Parking gear: P stands for Parking gear, also known as the parking position. 3. Other gears: R is the Reverse gear, N is the Neutral gear, and D is the Drive gear, also known as the driving position. 4. Sport mode: S or 2 represents the Sport mode. 5. Low gear: L or 1 is the Low gear, also known as the 1st gear. Below is additional information on the differences between manual and automatic transmissions: 1. Learning period: Manual transmission cars are more complex than automatic ones, so the learning period differs. Typically, learning to drive a manual transmission car takes at least one month longer than an automatic one. Due to the higher difficulty, the pass rate for manual transmission driving tests is also lower. 2. Driver's license: A manual transmission license is classified as C1, while an automatic transmission license is C2. Holders of an automatic transmission license cannot drive manual transmission cars, but those with a manual transmission license can drive automatic transmission cars. 3. Cost: Because manual transmission learning is more challenging and has a lower pass rate, its cost is generally cheaper than automatic transmission tuition fees. Typically, learning automatic transmission is more expensive.

How Many Days Does It Take for Car Paint to Dry Completely?

Generally, after a car is painted, it takes about two days to dry in the high temperatures of summer. In winter, the drying time depends on the temperature and can take up to four to seven days. If the paint is baked, it can dry in just two hours. Here is some relevant information: 1. After painting: If the vehicle is painted in a paint booth, it can be washed immediately after being taken out since it has already stayed in the booth for 3-4 hours. For vehicles painted at authorized 4S shops, they can be washed upon delivery by the staff, as the paint has undergone a proper baking process. Just remind the car wash staff to be careful. 2. Precautions: If the car has just been painted, avoid exposing the newly painted areas to water and dust. It's best not to drive the car in the rain, as the fresh paint is still delicate and can be marked by rainwater, leaving unsightly stains that may not be removable even by polishing.

Is a BMW's engine oil temperature of 120°C normal at high speed?

BMW's engine oil temperature of 120°C at high speed is normal. BMW cars are equipped with high-temperature engines, where the normal engine oil temperature tends to be higher than the coolant temperature. Detailed information about engine oil is as follows: 1. Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a car. 2. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are an essential part of lubricants.
