What Are the Uses of Automotive Antifreeze?

Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the vehicle is parked in cold winter conditions. Antifreeze should not be diluted with water. As a type of alcohol-based chemical reagent, antifreeze is designed to prevent freezing and rust. Adding water can alter its properties and reduce its effectiveness. Functions of antifreeze: Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Composition of antifreeze: The main components of antifreeze are 50% purified water, 40% methanol, and 10% other substances. Types of antifreeze: Antifreeze is generally categorized into three types: ethanol-water, glycerol-water, and ethylene glycol-water. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could lead to chemical reactions among the additives, rendering them ineffective.

How early can a car undergo its annual inspection?

A car can undergo its annual inspection up to 3 months in advance. For example, if the vehicle's inspection validity expires in September of this year, then the annual inspection period would be from July 1st to September 30th of the same year. There are several ways to check the annual inspection time. The most straightforward method is to refer to the vehicle's registration certificate and compulsory traffic insurance electronic policy, which display the vehicle's registration date. The registration month indicates the month when the annual inspection is due. Additionally, you can directly check the annual inspection sticker, which clearly states the validity period of the inspection. Important notes regarding annual inspection: Vehicles that fail the annual inspection must be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office will confiscate their license plates and prohibit further operation. Vehicles that do not undergo the inspection without valid reasons or fail the inspection are not allowed to be driven on the road or transferred to another jurisdiction. Vehicles that meet the scrapping conditions or have exceeded the prescribed service life will not be inspected, and their license plates will be revoked, their records deleted, and they will be scrapped.

Why does the car tire pressure monitoring light stay on after inflating the tires?

There are two reasons why the car tire pressure monitoring light stays on after inflating the tires: 1. The car tire pressure is too high. After repairing the tire, it is necessary to calibrate the air pressure of all four tires and then reset the tire pressure monitoring system. 2. The car sensor is malfunctioning. It is necessary to go to a professional repair shop for maintenance in time. Additional information: Precautions for inflating car tires are: 1. Pay attention to safety when inflating. Always use a pressure gauge to check the air pressure to avoid tire blowout due to over-inflation. 2. After stopping the vehicle, wait for the tires to cool down before inflating, as the tire temperature rises during driving, which affects the air pressure. 3. Check the valve stem. If the valve stem and valve core do not fit smoothly, with protrusions, depressions, or other defects, it will be inconvenient to inflate and measure the air pressure. 4. Pay attention to cleanliness when inflating. The air being filled should not contain moisture or oil to prevent the inner tube rubber from deteriorating and being damaged.

What is the function of pedestrian protection devices?

Pedestrian protection devices are designed to minimize injuries to pedestrians in the event of a collision. They work by using pressure sensors in the front bumper to detect a pedestrian collision. Upon detection, a specialized lifting mechanism quickly raises the engine hood a certain distance, providing more buffer space when a pedestrian's head or torso hits the hood. This helps avoid direct and violent impact with the rigid engine components. Taking Volvo as an example: this system is called the Collision Warning with Full Auto Brake (CWAB), which uses radar and cameras to detect pedestrians in front of the vehicle.

How to Handle 33 Demerit Points When the Points Are Not Enough?

Methods to handle 33 demerit points: 1. Consecutive demerit points incurred at the same time: Generally, the driver responsible for the violation should go to the traffic police violation handling office to process the violation information. If all 33 points are incurred by one person at the same time, the driver should, within 15 days, attend a 7-day course on subject one (written test) and take the exam at the place where the driver's license was issued or where the violation occurred. Within 10 days after passing the exam, the driver must also take the road driving skills test (subject two). After completing all the courses and passing the exams, the driver can retrieve their license. 2. Demerit points incurred at different times: If the demerit points are not incurred at the same time and are all violations captured by electronic surveillance, the 33 demerit points can be handled collectively by three driver's licenses linked to the vehicle. This means each license will bear 11 points. Since electronic surveillance can only capture the violating vehicle and not the driver, as long as the violation is confirmed, paying the fine is sufficient. Within the current scoring cycle, as long as there are no further violations, there will be no significant impact. After paying the fine, the points will automatically reset in the next scoring cycle.

Is Rust on the Car Chassis a Serious Issue?

Rust on the car chassis has a significant impact on the vehicle. The main effects are: 1. In mild cases, it affects the comfort of the ride and can easily impact other parts of the car. 2. In severe cases, it increases the likelihood of vehicle malfunctions, leading to traffic accidents. Once rust appears on the chassis, it should be addressed promptly. Additional Information: The maintenance rules for the car chassis are: 1. In winter, thorough chassis cleaning and rustproofing treatment are necessary for maintenance. First, the chassis must be thoroughly cleaned. If there is excessive mud or dirt on the chassis, a degreasing cleaner should be used to wash it, revealing the original "true color" of the chassis. Only then can rustproofing treatment begin. 2. At professional auto beauty shops, the car can be lifted on a hoist for chassis cleaning, wiping, and then rustproofing treatment. It is important to note that after cleaning, the chassis must be completely dry before rustproofing treatment can proceed. 3. During the treatment, ensure an even application of the coating to form a long-lasting, uniform rustproof layer. After completing all steps, allow 5-10 minutes of natural air drying for the rustproofing treatment to be fully finished.
