The car radiator has maximum and minimum warning lines marked on it. As long as the water level is between these two warning lines, there is no problem. Of course, when the level is below the minimum line, the car can still be driven, but it serves as a reminder for the owner to add coolant. Coolant also offers the following advantages: Anti-corrosion function: The engine and its cooling system are made of metal, including copper, iron, aluminum, steel, and solder. These metals, when exposed to high temperatures and water over time, can corrode and rust. Coolant not only prevents corrosion to the engine cooling system but also has anti-corrosion and rust-removal functions. Higher boiling point of coolant: The boiling point of water is 100 degrees Celsius, while high-quality coolant typically has a boiling point above 110 degrees Celsius. This makes coolant less likely to boil over in summer compared to water. Coolant can also prevent scaling:

What Causes Oil Leakage in the Drive Axle?

The causes of oil leakage in the drive axle are: 1. Loose or damaged oil filler and drain plugs; 2. Worn or hardened oil seals, incorrectly installed oil seals, or misalignment between oil seals and shaft journals; 3. Sealing gaskets that are too thin, hardened, or damaged; 4. Loose or damaged fastening screws; 5. Casting defects or cracks in the axle housing; 6. Excessive gear oil filling, leading to increased internal pressure during operation. The drive axle consists of the main reducer, differential, half-shafts, and axle housing. The functions of the drive axle are: 1. Transmitting the engine torque from the universal drive assembly to the drive wheels through the main reducer, differential, and half-shafts, achieving speed reduction and torque increase; 2. Changing the direction of torque transmission via the bevel gears of the main reducer; 3. Enabling differential action to ensure the inner and outer wheels turn at different speeds; 4. Supporting loads and transmitting torque.
