1 Answers

When the temperature is high, choose gear oil with high viscosity; conversely, when the temperature is low, choose gear oil with low viscosity. In regions where the temperature does not drop below -10 degrees Celsius, 90-grade oil can be used year-round. In cold areas where the temperature does not drop below -26 degrees Celsius, 80w/90 oil can be used year-round. In extremely cold regions where the temperature falls below -26 degrees Celsius, use 75w-grade oil in winter and switch to 90-grade oil in summer. In other areas, 85w/90 oil can be used year-round. Definition of Gear Oil: Gear oil mainly refers to the lubricating oil for transmissions and rear axles. Function of Gear Oil: Automotive gear oil is used in gear transmission mechanisms such as steering gears, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays a crucial role in lubrication, anti-wear, cooling, heat dissipation, anti-corrosion, rust prevention, cleaning, and reducing gear surface impact and noise.

What to Do When the Interior Windshield Cannot Be Cleaned Properly?

The solutions for an interior windshield that cannot be cleaned properly are: 1. Apply toothpaste on it, wet it with water, then wipe with a sponge or soft cloth, followed by a final wipe with glass cleaner; 2. First wipe with a damp cloth, then use a clean damp cloth dipped in some alcohol or liquor to scrub the car glass vigorously; 3. Try using a polishing machine with polishing compound to remove stubborn stains. During regular glass maintenance, choose the appropriate glass cleaner based on the season and weather conditions. When the windshield surface appears blurry, cleaning it with the right glass cleaner can make it much clearer. If you notice random reflections on the glass at night, you can also use glass cleaner to wipe it down.

What is an Airbag?

An airbag is a cushioning device that rapidly inflates when a vehicle experiences a collision and sudden deceleration, protecting occupants from impacting the interior of the vehicle. As a passive safety feature, airbags help reduce injuries caused by frontal impacts. The airbag consists of a flexible rubber capsule filled with compressed air or liquid medium, utilizing the compressibility of air and fluidity of water to provide elasticity. When a vehicle collides with an obstacle (primary collision), and subsequently when occupants collide with interior components (secondary collision), the airbag rapidly deploys a gas-filled cushion between these two events. This allows occupants to land on the cushion during inertial movement, thereby cushioning the impact and absorbing collision energy to mitigate occupant injuries.

How to Fix a Non-Functional Car Navigation System?

Most car navigation systems are based on the Android operating system. If there is a power button or a touch-sensitive switch near the navigation system, try turning it off and restarting it. Since car navigation systems typically do not have their own power source, you can also try turning off the vehicle and restarting it to check the navigation system's status. Here are some considerations when purchasing a car navigation system: 1. Test the system's accuracy: Choose one or two familiar routes or a newly opened hotel to see if the system can accurately display the car's location. Streets and routes are constantly changing, so the system must offer regular update services. 2. Consider the system's storage capacity: In the U.S., storing nationwide maps requires at least three CDs. Therefore, the car navigation system must have a sufficiently large hard drive memory.
