What does SAE mean?

SAE stands for the Society of Automotive Engineers, which refers to the viscosity grade classification of gear oil. Here are the detailed explanations: 1. Gear oil can be divided into single-grade viscosity type and multi-grade all-weather type. 2. The single-grade viscosity type can be further divided into high-temperature type and low-temperature type. 3. The high-temperature type has labels like SAE90 and SAE140, where the number after SAE indicates the oil viscosity at 100°C. A larger number indicates higher oil viscosity. The low-temperature type has labels like SAE75W, where W stands for low-temperature type, and 75 is the viscosity. A smaller number indicates better low-temperature performance. 4. The multi-grade all-weather type has labels like SAE80W/90. The number before the slash indicates the low-temperature viscosity performance in winter, where a smaller number means lower low-temperature viscosity, better fluidity, and better low-temperature resistance. The number after the slash indicates the high-temperature viscosity performance, where a larger number means higher high-temperature viscosity and better high-temperature resistance.

What is the difference between forged and cast wheels?

The differences between cast wheels and forged wheels are as follows: 1. Different manufacturing processes. (1) Casting involves melting metal into a liquid that meets certain requirements, then pouring it into a mold. After cooling, solidification, and cleaning, a casting with predetermined shape, dimensions, and performance is obtained. (2) Forging, on the other hand, uses forging machinery to apply pressure to metal blanks, causing plastic deformation to obtain forgings with certain mechanical properties, shape, and dimensions. 2. The costs of the two types of wheels also differ. (1) The casting process is relatively simple and straightforward, making it easy for mass production, so the cost is relatively lower. (2) Forging, due to its more complex procedures, has a higher production cost. 3. The strength of the two differs. Forged wheels are made through continuous hammering, resulting in very compact molecular structure and orderly arrangement. This gives them better strength and toughness compared to cast wheels, meaning forged wheels are more robust.

What to Do When Temporary License Plates Expire?

Temporary license plates that have expired but have not yet been replaced with formal vehicle license plates can apply for an extension to continue using temporary vehicle license plates. Here are the detailed instructions: 1. An application can be made for expired temporary license plates, but the temporary driving license issued by the vehicle management office cannot exceed three times. 2. A local temporary license plate can be extended three times, which amounts to 21 days. During this period, driving is only allowed within the city and not outside the urban area. Otherwise, it will be considered as driving without a license plate. 3. To apply for temporary license plates, you need to bring the temporary permit, vehicle purchase invoice, new vehicle certificate, compulsory insurance certificate or import certificate, and copies of relevant documents to the public security authority for application. 4. The application process can be completed in about one working day, and will be postponed in case of holidays.

What is the Difference Between 1.6T and 2.0T?

1.6T and 2.0T mainly differ in the following aspects: 1. Different maintenance costs. The 2.0T requires a larger turbo or higher turbo pressure, so the engine operates at higher temperatures and pressures, necessitating engine oil that is more resistant to high temperatures. 2. Different power outputs. The 2.0T engine delivers stronger power, with greater torque and horsepower output. Overall, it is more powerful than the 1.6T. 3. Different fuel consumption. Engines with larger displacements intake more air, requiring more fuel to mix with the air for combustion. Therefore, among turbocharged engines, the smaller the displacement, the more fuel-efficient it is. Thus, the 1.6T consumes less fuel than the 2.0T.

How many liters of coolant are needed for a Mercedes GLK coolant replacement?

Mercedes GLK requires approximately 6 liters of coolant for a replacement. Coolant is a special additive-containing fluid primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and year-round protection against scale and corrosion. Can coolants be mixed: It is necessary to use the same brand of coolant. Different brands of coolant may have varying production formulas. Mixing them could lead to chemical reactions between additives, rendering them ineffective. How to determine if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it may indicate low coolant levels, though it could also be due to excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Check the water level marks on the coolant tank. The normal coolant level should be between the maximum and minimum marks. If it is below the minimum mark, it indicates a shortage of coolant.

Does Parking on a Slope Affect the Car?

Long-term parking on a slope can have several impacts on a car: 1. Damage to the handbrake braking system: When parking on a slope, the handbrake is the first to bear the brunt. The handbrake works by pulling the brake shoes via a cable to secure the vehicle. On a slope, the handbrake cable continuously bears the component of the car's weight parallel to the slope, which over time can cause the cable to "fatigue," affecting the handbrake's braking performance and potentially rendering it ineffective. If not careful during regular use, this could easily lead to a rolling accident after parking. 2. Impact on the suspension: When parked on a slope, the suspension on the downhill side bears greater pressure. Prolonged exposure to this condition can cause uneven aging and stiffness between the front and rear suspensions, affecting ride comfort. 3. Risk of rolling: Long-term parking on a slope increases the likelihood of the handbrake aging and failing, making the car prone to rolling accidents.
