Should I Service My Car Before or After a Long Trip?

It is better to service your car before a long trip. Pay attention to the following aspects during the service: 1. Check the battery voltage during the service. 2. Check the antifreeze level, and if it is too low, promptly add the same type of antifreeze according to the standard scale on the replenishment tank. 3. Also, check whether the thermostat is working properly. 4. Pay attention to the selection of engine oil; it is best to use all-season oil such as 5W-30 or 0W-30. 5. Check whether there is too much carbon buildup inside the engine. In winter, especially during cold starts, excessive carbon buildup will definitely make it difficult to start the vehicle. 6. Check the windshield washer fluid level, and if it is too low, replenish it promptly.

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses", the 2021 driver's license test for Subject 1 consists of 100 questions, divided into single-choice questions and true/false questions, with each question worth 1 point for a total score of 100. If 11 questions are answered incorrectly during the test, the system will automatically submit the paper and end the test. Subject 1, also known as the Subject 1 theory test or driver theory test, is part of the motor vehicle driver's license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and other related knowledge. The test is conducted on a computer with a time limit of 45 minutes. The content of Subject 1 includes: driver's license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized buses and trucks; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Notes for Subject 1 test: Candidates should pay attention to their attire, no slippers are allowed, electronic devices and bags are not allowed in the examination room, bring ID cards, and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in lockers before entering the examination room. Upon entering the examination room, the identity verification station will assign seats. After finding the seat, start the test, ensure the camera is aligned with yourself, and follow test discipline. If you fail the first time, there is a retake opportunity on the same day; if you fail again, you need to pay and reschedule. After the test, queue to collect the score report and sign it; unsigned reports are considered invalid. There is no limit to the number of times you can schedule the Subject 1 test. Each subject can be taken once, and if you fail, you can retake once. If you do not take the retake or fail the retake, the test ends, and the applicant must reschedule. For Subject 2 and Subject 3, there are only 5 test attempts, and Subject 2 and Subject 3 tests must be scheduled at least 10 days apart. If you fail the Subject 3 safe and civilized driving knowledge test, the passed road driving skills test scores remain valid. There are 3 subjects in the driver's test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as Subject 4.

Can Flood-Damaged Vehicles Be Transferred and Retitled?

Yes, they can be transferred. Information about flood-damaged vehicles is as follows: 1. Definition of flood damage: Flood-damaged vehicles refer to cars that have been submerged in water, typically meaning the engine and transmission have been soaked, with water levels exceeding the wheels and body seats, and the vehicle's underbody components having prolonged contact with water. Such vehicles pose significant risks, as the electrical systems are prone to short circuits and fires. 2. Repair of flood-damaged vehicles: Flood-damaged vehicles can be repaired to some extent, but even after repairs, they still carry serious hidden dangers. The longer the immersion time, the higher the likelihood of malfunctions. This is similar to a watch falling into water—even if it is disassembled and dried, the watch will still malfunction and cannot be completely repaired.

What does PCV valve mean?

PCV is the abbreviation of POSITIVE-CRANKCASE-VENTILATION in English, which means the positive ventilation control system of the crankcase (or oil pan) in Chinese. The PCV valve consists of a valve body, valve, and valve cover, and cannot be disassembled. The PCV valve is generally installed between the valve rocker cover and the intake manifold. The following is relevant information about the PCV valve: 1. Function of the PCV valve: At the end of the engine combustion process, some unburned mixture leaks into the crankcase under high pressure from the piston rings. These blow-by gases will escape from the crankcase into the atmosphere, causing pollution. If these blow-by gases are not removed, they will also dilute the oil in the crankcase, causing the oil to deteriorate and leading to premature wear of engine components. Therefore, a PCV valve is installed on the valve cover to allow these exhaust gases to re-enter the engine through the intake manifold for re-combustion. 2. PCV valve inspection method: After reinstalling the PCV valve, remove the crankcase intake pipe from the air filter, and lightly cover the pipe opening with a thin piece of paper. When the pressure in the crankcase decreases, the thin paper should be visibly sucked towards the pipe opening. In addition, after stopping the engine, remove the PCV valve and shake it by hand to check. If a "click" sound is heard, it indicates that the PCV valve is flexible and usable.
