The differences between car radiator coolant and antifreeze are as follows: 1. Antifreeze has a freezing point and provides antifreeze protection, preventing the radiator from freezing in winter. Common antifreeze ratings include -16℃, -25℃, -35℃, and -45℃ (used in extremely cold regions). 2. Radiator coolant has a freezing point of only 0℃, making it suitable only for southern regions or provinces where it does not snow in winter. A freezing point of 0℃ means that if the local temperature drops below 0℃, radiator coolant cannot be used. Precautions are as follows: 1. If you are a car owner in the south using radiator coolant and plan to drive to northern regions, you should switch to antifreeze before traveling. 2. If antifreeze is not replaced in time, the radiator may freeze. For vehicles frequently traveling across regions, using antifreeze is recommended.

Why was Subject 4 automatically cancelled?

Subject 4 was automatically cancelled because after passing the Subject 3 road test, the system automatically scheduled the Subject 4 exam for the same day. Therefore, when candidates try to make an appointment, the system will display "duplicate appointment" and automatically cancel it. Introduction to Subject 4: Subject 4, also known as the Subject 4 theoretical test or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of "Order No. 139 of the Ministry of Public Security of the People's Republic of China", the Subject 3 test was divided into two parts: in addition to the road test, a safety and civilization knowledge test was added, commonly known as "Subject 4", which assesses "driving ethics". Subject 4 test content: Includes safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and post-accident handling knowledge.

Must traffic violations captured by high-definition cameras be handled by the offender in person?

Traffic violations captured by high-definition cameras must be handled by the offender in person, just like tickets issued by traffic police on-site. Only the offender's driver's license can be used to process the violation, and it is not allowed to use someone else's driver's license to handle it on their behalf. More details about violation handling are as follows: If someone else's driver's license is used to handle the violation, that license must be bound to the vehicle. Each motor vehicle can only use up to three driver's licenses for deducting points, and each driver's license can only handle violation records for up to three motor vehicles. Otherwise, if the traffic police department discovers that someone else's license was used to handle the violation or any other irregularities, they will refuse to process it, and severe cases may result in corresponding penalties.

Do You Need to Turn on AC for Window Defogging?

Window defogging requires turning on the AC. The appearance of fog indicates that the air inside the car is very humid. Using humid air continuously for defogging is ineffective. Reducing air humidity makes it less likely for fog to form, hence turning on the AC for defogging yields the best results. Defogging does require turning on the AC, but no manual operation is needed. As long as the defogging switch is activated or the air direction is set to the windshield mode, the AC switch will automatically turn on, and the circulation mode will switch to external circulation. Turning on the AC and external circulation ensures the fastest and most effective defogging. Some cars allow manual deactivation of the AC, while others do not. If the AC is turned off in defogging mode, defogging can still occur, but sometimes the effect may be worse, with fog persisting for a long time or even worsening. Turning on the AC is not about using cold air to blow away the fog but rather utilizing the dehumidifying function of the air conditioning system. The AC switch controls the air conditioning compressor. Once turned on, a signal is sent to the compressor, which then starts working to cool under normal circumstances and stops when turned off. This compressor can only cool and cannot generate heat. Whenever it operates, it cools, meaning the AC is a cooling switch. Heating does not require turning on the AC, as the heat for warm air does not come from the compressor.

Can a vehicle be transferred to another location?

Vehicle can be transferred to another location. For the transfer of a vehicle purchased in a different location, both the vehicle's original registration transfer-out and the new registration transfer-in are required. When processing the transfer-out of the vehicle's original registration, the vehicle must be inspected at the local used car market transfer hall, and the vehicle's registration must be completed to extract the vehicle's records. With the vehicle's records or transfer-out certificate and registration certificate, proceed to the relevant office to handle the vehicle purchase transfer-out procedures and extract the vehicle purchase tax records.

Can a car run long distances in 40-degree high temperature weather?

40-degree high temperature weather is acceptable for long-distance driving, but be mindful not to drive for excessively long durations. Precautions for driving in high temperatures: Drowsiness: Driving in hot weather can easily cause drowsiness. If you feel tired, be sure to rest at a nearby hotel and avoid stopping randomly. Before embarking on a long-distance trip on the highway, ensure you have adequate rest to prevent sudden fatigue. Distraction: Summer can easily make people fatigued. While driving, if traffic is light and road conditions are good, it's easy to relax your vigilance, increasing the risk of accidents. When feeling tired or distracted, drivers can listen to some upbeat music to stay alert.
