Is Rusting of the Steering Shaft Common in Cars?

Rusting of the steering shaft is common in cars, and it is a normal occurrence. If the rusting is not severe, it will not affect the safe use of the vehicle. However, if the rusting is severe, it can compromise driving safety. The primary cause of rusting on the steering shaft is the prolonged use of cleaning agents to wash the engine and steering gear housing. It is advisable to address this issue promptly. Recommendations for treating rust on the steering shaft: Use fine sandpaper to remove and clean the rust from the steering shaft. Then, melt white candle wax at high temperature and apply the melted wax to the metal part of the steering shaft. The thickness of the wax application can be adjusted as needed. The wax coating helps prevent moisture and isolate air, ensuring the shaft remains rust-free for several years. Alternatively, you can apply rosin solution (made by dissolving rosin powder in alcohol), which serves the same purpose as wax but offers slightly better moisture resistance. Steering shaft maintenance methods: The universal joint has grease lubrication holes, so regular lubrication is essential. However, some maintenance-free drive shafts do not require grease application. Avoid starting in high gear or abruptly releasing the clutch, as these actions can impose significant impact forces on the drivetrain, potentially damaging components, including the drive shaft assembly. Overloading the vehicle or excessive speeding should be strictly avoided, as exceeding the torque capacity of the drive shaft can cause damage and reduce its lifespan. Regularly inspect the drive shaft's mounting bracket for cracks, check if the support rubber is damaged, and ensure all fastening bolts and nuts are secure. Also, verify that the drive shaft is not deformed, as these issues can lead to abnormal noises and vibrations in the drivetrain. To maintain the drive shaft's dynamic balance, frequently check if the balance weld tabs are intact. When reinstalling the drive shaft after disassembly, ensure alignment marks are correctly matched.

What is the oil specification for the Corolla?

The recommended oil grades for the Corolla as per the official manual are 0W-20, 5W-20, and 5W-30. Any oil grade that meets these specifications can be used. Depending on driving habits, owners may choose different oil grades to better protect the engine. Here is some extended knowledge about engine oil: 1. Classification: Mineral oil, semi-synthetic oil, and full-synthetic oil. 2. Lubrication effectiveness: Mineral oil performs the least effectively, full-synthetic oil performs the best, and semi-synthetic oil is in between. 3. Oil change intervals: Mineral oil should generally be changed every 5,000 kilometers, semi-synthetic oil every 7,500 kilometers, and full-synthetic oil every 10,000 kilometers.

Can Flood-Damaged Cars Spontaneously Combust?

Flood-damaged cars do not spontaneously combust. Below is relevant information about flood-damaged vehicles: Introduction to Flood-Damaged Vehicles: A flood-damaged vehicle refers to a car that has been submerged in water, typically meaning the engine and transmission have been waterlogged, with immersion depth exceeding the wheels and vehicle seats, and prolonged contact between the underbody components and water. Such vehicles pose significant risks, as their electrical systems are prone to short circuits. While 'flood-damaged cars' can be repaired to some extent, even after repairs they harbor serious hidden dangers. The longer the immersion duration, the higher the probability of malfunctions occurring. This is analogous to a watch dropped into water—even after disassembly and drying, the watch will still malfunction and cannot be completely restored. Hazards of Flood-Damaged Vehicles: The hazards of water-submerged vehicles are enormous. If a motor vehicle is submerged, it can easily lead to rusting of body components, shortening its service life and reducing safety performance. For instance, water damage can cause corrosion and rusting of the vehicle's wiring, leading to sudden engine shutdown or spontaneous combustion due to short circuits while driving, with potentially catastrophic consequences. Additionally, the repair costs for water-submerged vehicles are extremely high, with repairs for severely water-damaged vehicles often exceeding 50% of the vehicle's value. Moreover, insurance claims for such vehicles are often highly problematic.

Do Hybrid Vehicles Require Purchase Tax?

Hybrid vehicles do not require purchase tax. According to the latest announcement from the Ministry of Finance, new energy vehicles are exempt from vehicle purchase tax. The types of new energy vehicles include pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles. It is advisable to consult in advance before purchasing. The exemption of purchase tax for hybrid vehicles is a policy introduced by the state to encourage the production and sales of new energy vehicles. New energy sources such as electricity and solar power are environmentally friendly and help conserve non-renewable energy resources. Currently, there are three main types of hybrid vehicles on the market, as follows: Mild hybrid models represented by the Changan Eado Blue Core Edition and the Geely Borui MHEV. Medium hybrid models represented by the Toyota Corolla, Toyota Levin, Honda CR-V Hybrid, and Beijing Hyundai Sonata Hybrid. Plug-in hybrid models represented by the BYD Tang, BYD Qin, SAIC Roewe ei6, GAC Trumpchi GS4 Plug-in Hybrid, Great Wall WEY P8, and Geely Borui GE. The first type of hybrid vehicles adopts a 48V mild hybrid system with a battery capacity of only 1-2KWh. The second type represents typical hybrid vehicles with larger battery capacities, but these models do not support pure electric driving. The third type of hybrid vehicles has a battery capacity of around 10KWh, enabling a driving range of 50-100 kilometers.

What is the implementation date of the China VI-b standard?

The implementation date of the China VI-b standard is July 1, 2023. Here is some information about the China VI standard: 1. Introduction: The implementation of the China VI emission standard will be divided into two phases, "China VI-A" and "China VI-B," corresponding to July 1, 2020, and July 1, 2023, respectively. China VI-A can be seen as a transitional phase from China V to China VI. Some provinces and cities will implement the China VI emission standard ahead of schedule, with specific dates varying. 2. Regulations: After the implementation of the China VI emission standard, all vehicles sold and registered must meet the requirements of the China VI emission standard. Vehicles below the emission standard will be prohibited from being sold, registered, or transferred. China IV and China V emission vehicles can only be scrapped or relocated to regions where the China VI standard has not yet been implemented. 3. Legal provisions: Article 4, Clause 15 of the "Three-Year Action Plan for Winning the Blue Sky Defense War" issued by the State Council clearly stipulates that starting from July 1, 2019, key regions, the Pearl River Delta region, and the Chengdu-Chongqing region will implement the China VI emission standard ahead of schedule.

What are the tips for gear shifting in Subject 3?

Subject 3 gear shifting the most important tip is to pay attention to the timing of gear shifting. The following are the details to pay attention to when shifting gears: 1. Start with first gear: Some students forget to start with first gear and use second gear or even higher gears, which will cause the front of the car to suddenly rush out, which is extremely dangerous. 2. Shift gears step by step: Subject 3 road test strictly prohibits skipping gears. You can only shift gears step by step from 1-2-3-4-5. If you shift to the wrong gear, don’t panic, just move the gear lever back to the neutral position and immediately shift to the correct gear. 3. Look at the road ahead when shifting gears: Some people can’t remember the specific position of each gear, so they like to look down at the gear every time they shift. Such behavior is considered unqualified in Subject 3. The correct operation is to operate the steering wheel with the left hand, shift gears with the right hand, and look ahead. The behavior of looking down to shift gears can easily cause rear-end collisions or deviations. 4. After shifting gears, the right hand leaves the control lever: Mainly because students are not as familiar with the perception of the vehicle as experienced drivers, and single-handed operation is more likely to cause deviations and confusion in emergency situations. At the same time, if the right hand is always on the gear lever, unconscious shaking of the gear lever may be misjudged by the system as incorrect gear shifting behavior.
