How Many Liters of Antifreeze Are Generally Needed?

Generally, antifreeze requires about 5-7 liters. The amount of antifreeze to be added varies for each vehicle. After adding antifreeze, you can check the scale on the auxiliary water tank. Typically, there are two marks on the auxiliary water tank: one for the maximum level and one for the minimum level. The antifreeze must be between these two marks—neither too much nor too little. Below is more detailed information: 1. The engine's antifreeze must have characteristics such as freeze protection, boil-over prevention, corrosion resistance, scale prevention, and no foam formation, and it should not be affected by seasons or regions. Among these, the freezing point and boiling point are the basic indicators of antifreeze. 2. The coolant is prepared by mixing antifreeze with water in a certain ratio. Automobile manufacturers usually specify the mixing ratio for different low-temperature antifreeze grades in the user manual and also designate the type of antifreeze, which should not be mixed. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze functionality. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking.

What does the P in automatic transmission mean?

P stands for Parking—the parking gear, where P is the abbreviation. After parking, it is necessary to engage the P gear to prevent the vehicle from rolling, especially when parking on a slope. The general method to engage P gear is to press the brake pedal and wait until the vehicle comes to a complete stop before shifting or using the electronic button for models equipped with one. Automatic transmissions have the following gears: 1. P gear: Represents the parking gear. When parking the vehicle, shift into P gear, including when shutting off the engine or during prolonged idling. 2. R gear: Represents the reverse gear. Shift into R gear when reversing the vehicle. 3. N gear: Represents the neutral gear, which is the same as the neutral gear in manual transmissions. It can be used for short-term parking. 4. D gear: Represents the drive gear. When shifted into this gear, the vehicle moves forward. In this gear, the transmission automatically shifts between 1st and the highest gear based on the vehicle's speed and throttle conditions. 5. S gear: Represents the sport mode. When shifted into this gear, the transmission delays shifting, keeping the gear at higher RPMs for longer to increase vehicle power, though this naturally consumes more fuel.

What is the correct method to check car engine oil?

Correct methods to check car engine oil include the smell test, the rub test, the color test, and the light test. The engine needs sufficient oil for lubrication, but more is not always better. Insufficient oil can cause serious damage to engine components due to poor lubrication. Correct methods to check car engine oil: Smell test: Pull out the dipstick and bring it close to your nose. If there is a strong acidic or foul smell, it indicates the oil has deteriorated and should be changed. Rub test: Take some old oil and rub it between your thumb and forefinger repeatedly. Good-quality oil will feel smooth, produce little residue, and have no gritty feeling. If you feel impurities, poor viscosity, or even a rough texture, it's time to change the oil. Color test: Place a few drops of old oil on a clean white filter paper. After the oil spreads, good-quality oil will leave no powder, feel dry and smooth to the touch, and show a clear yellow diffusion ring. If the oil appears dark brown with visible impurities, it should be replaced. Light test: Hold the dipstick at a 45-degree angle under light and observe the oil droplets. If you can clearly see no metal particles, the oil is still good. If there are many particles, the oil should be changed.

Can an automatic car be shifted into neutral while driving?

Automatic cars should not be shifted into neutral while driving. Here are the reasons: 1. Shifting an automatic car into neutral while driving will reduce the vehicle's braking force, which can easily lead to rear-end collisions. When the car is coasting in neutral, the connection between the engine and the drive wheels is lost, and the car moves forward solely by inertia. In emergency situations requiring braking, all braking force must be provided by the brakes alone. When coasting in gear, the engine itself provides some braking effect, which, combined with the brakes, shortens the braking distance. Additionally, coasting in neutral can easily cause the engine to stall, leading to failure of the brake booster and reduced braking performance. 2. Shifting into neutral does not save fuel and can sometimes even consume more fuel, which is related to the working principle of electronic fuel injection engines. Electronic fuel injection engines can determine the amount of fuel injection based on the computer program. When coasting in gear, if the driver releases the accelerator, the computer will put the car into coasting mode, during which the engine does not inject fuel for a long period. However, if coasting in neutral, the computer will put the car into idle mode, and the engine continues to inject fuel. This is why coasting in neutral sometimes consumes more fuel.

Is U-turn Allowed at a Red Light Intersection?

U-turns are not allowed at red light intersections as they can easily lead to traffic accidents. According to Article 51 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China: When motor vehicles pass through signal-controlled intersections, they shall proceed as follows: At intersections with designated turning lanes, enter the appropriate lane based on the intended direction; when the signal permits, pass through in sequence. Other situations where U-turns are prohibited include: U-turns are prohibited where there are 'No U-turn' or 'No Left Turn' signs: If there is a no U-turn sign, U-turns are not allowed at that intersection. A U-turn is essentially an extension of a left turn, so if there is a no left turn sign at an intersection, U-turns are also prohibited there. U-turns are prohibited when there is no left turn lane: Even in the leftmost lane, if there is no sign permitting left turns, U-turns are not allowed. U-turns are prohibited from the second left turn lane: When a vehicle is in the second left turn lane, it cannot make a U-turn. In the absence of any signage, U-turns are only permitted from the innermost left turn lane. U-turns are prohibited on highways: Making a U-turn by crossing the central divider on a highway is illegal and punishable by a fine and 12 demerit points. If you miss an exit on the highway, continue to the next exit to leave the highway; never attempt an illegal U-turn.

Where Can Tire Pressure Be Monitored?

Tire pressure monitoring devices vary based on the installation location of the sensors. Common tire pressure monitoring devices are usually found in the vehicle's onboard computer, while others may be located on the central console. The methods for monitoring tire pressure are as follows: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically issue an alert. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring Systems (TPMS): TPMS combines the advantages of both systems mentioned above. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system can.
