Car starters can be repaired as long as the damage is not catastrophic or the starter's physical structure is completely deformed. Symptoms of a damaged starter: When turning the ignition switch to the start position, you may hear the impact sound between the starter drive gear and the flywheel teeth. The starter does not rotate when the ignition switch is turned on, and the solenoid switch emits abnormal noises. The starter spins freely when the ignition switch is turned on. The charging system is normal when the ignition switch is turned on, but the starter does not respond. Causes of starter damage: Insufficient battery power, loose terminal connections, short circuit in the starter solenoid switch coil or poor contact of the contact disc, burnt relay contacts, short circuit or burnout of the relay magnetic coil, physical deformation of the starter's internal armature shaft, worn brushes, poor spring contact, dirty commutator, prolonged starting time, not used according to the specified time, increased gap between the shaft and the housing. Starter maintenance recommendations: The starter is a valuable component in a car and is not easily damaged. However, to extend the starter's service life, proper usage methods must be followed. During engine starting, the starter draws 300-400Ah of electricity from the battery. To prevent overcurrent or damage to the battery, the starting time should not exceed 5 seconds. Starting difficulties are common in winter. During multiple starts, each starting time should not be too long, and appropriate intervals should be left between starts.

As an experienced car enthusiast who frequently tinkers with vehicles, I believe whether a faulty car starter can be repaired depends largely on the extent of damage. For minor issues like poor contact at the terminals or carbon buildup, it's entirely possible to fix it yourself by cleaning or replacing a small part, costing just a few dozen bucks with some DIY effort. However, if the solenoid coil is burnt out or the starter motor gears are severely worn, repairs become extremely troublesome. Mechanics might advise you to replace it outright, as disassembling and reassembling could lead to recurring issues. I've had this experience before—my starter made clicking noises but wouldn't work, and after inspection, it turned out the carbon brushes were worn short. Replacing them at a small cost revived it. But if even the gears are slipping, replacing the entire starter is the long-term solution. When it comes to car repairs, if you're unsure, it's best to consult a professional technician for a proper diagnosis. They can quickly determine if it's worth repairing with their tools. Safety shouldn't be compromised; a car that won't start leaves you stranded.

What does remote parking mean?

Remote parking refers to the function that allows the car owner to remotely start the vehicle and control its forward/backward movement as well as steering left or right within a range of approximately 10 meters using a remote control similar to a slide phone. Models equipped with this feature include the BMW 7 Series and BYD Qin. The remote parking function mainly includes three types: remote entry/exit, remote parking in, and remote parking out. Here are the detailed introductions: 1. Entry/Exit: When parking, the driver can stop the car in front of the parking space and then use the remote control to maneuver the vehicle into the space after getting out. When retrieving the car, the driver can start the engine and activate the remote parking system from outside the vehicle using the remote control, then control the vehicle to exit the parking space. This function is suitable for narrow vertical parking spaces or scenarios where it's difficult to open car doors. 2. Remote Parking In: The driver can first activate the remote parking system inside the vehicle, search for and confirm the target parking space, then shift to P gear, engage the EPB, and exit the vehicle. The remote control can then be used outside the car to complete the parking process. This function is generally suitable for parallel, vertical, and inclined parking spaces. 3. Remote Parking Out: The driver can first start the engine and activate the remote parking system from outside the vehicle using the remote control, then continue to issue parking-out commands, allowing the remote parking system to control the vehicle's exit. This function is generally suitable for parallel parking spaces.

Are New Energy Vehicles Charged Highway Tolls?

New energy vehicles are required to pay highway tolls. Both new energy electric vehicles and conventional fuel-powered vehicles are subject to toll charges. Electric vehicles that are legally registered and licensed are permitted to drive on highways, while low-speed electric vehicles (such as elderly mobility scooters) and unregistered electric vehicles are not allowed. Additional Information: Below are some considerations for new energy vehicles when driving on highways: 1. Monitor Battery Level: Since electric vehicles rely solely on battery power during operation, it is essential to pay attention to the remaining range before entering a highway to avoid running out of power midway. If the battery level is insufficient, drivers can recharge at the nearest rest stop. It is advisable to familiarize oneself with the locations of charging stations along the route before setting out. 2. Pay Attention to Load: Similar to fuel-powered vehicles, excessive load in an electric vehicle will require more power during driving, leading to reduced range.

What are the five major signs before a car tire blowout?

Five major signs before a car tire blowout are as follows: 1. Tire sidewall cracks: Not all issues with tires are concentrated on the tread; the sidewalls can also develop problems. By inspecting the sidewalls for visible cracks and cuts, these small grooves can indicate potential future air leaks or even worse, tire blowouts. These tire failures should be avoided at all costs. 2. Tread wear indicator bars: Tread wear indicator bars are flat rubber strips embedded perpendicularly along the tread grooves. If you notice one or two of these bars during inspection, it means the tread depth has significantly reduced. Extra caution is needed when driving on wet or slippery roads. If almost all the indicator bars are visible, it's time to replace the tires as soon as possible. 3. Excessive vibration and shaking: Vehicle shaking can be caused by various factors, such as tire misalignment, imbalance, or issues with the shock absorbers. However, shaking can also indicate internal tire problems. Even if the tires aren't the root cause, prolonged shaking can degrade tire performance and lead to tire issues soon after. 4. Tread depth: The tread depth should always be greater than 1.6 mm. If you frequently drive on low-traction wet roads, it's best to maintain a tread depth at least twice this value. A tread depth gauge can be used to measure this accurately. 5. Bulges and blisters on the tire: In some cases, the outer surface of the tire may develop bulges or blisters due to insufficient strength, similar to an aneurysm in a blood vessel. If the vehicle isn't taken to a repair shop promptly, these weak spots can lead to sudden tire blowouts.

What is Sheet Metal Repair?

Automotive sheet metal is a technical method of car repair. In this context, automotive sheet metal is equivalent to automotive sheet metal repair, which refers to the process of restoring the car body after a collision. This includes all tasks except for the anti-corrosion and decorative painting work on the car body. Examples include analyzing car body damage, measuring the car body, shaping the sheet metal, stretch correction, stress-relief welding, as well as assembling and adjusting car body accessories. Here are situations where sheet metal repair is required: 1. Impact-induced dents: Impact-induced dents require sheet metal repair. Dents in sheet metal parts can be repaired using hammering or pulling methods. Different approaches are used depending on the specific situation. Of course, the process varies based on the severity of the dent, and the material of the car body must also be considered. 2. Warping or skew deformation: Methods for repairing warped or skewed sheet metal parts. Sheet metal parts may become warped or skewed due to impacts, scratches, or improper use. These deformations can be corrected using mechanical methods or flame heating and hammering techniques. 3. Cracks or punctures: Methods for repairing cracks or punctures in sheet metal parts. For surfaces damaged by impact or punctures, adhesive patch repairs can be used. Common adhesives currently in use include epoxy resin glue, phenolic resin glue, and copper oxide adhesives. 4. Cracks or severe local damage: For these two scenarios, traditional car repairs would involve welding or repair methods. However, 4S shops nowadays typically opt for direct replacement.

What is the general composition of a wheeled vehicle's running system?

The running system of a wheeled vehicle is generally composed of the frame, axle, wheels, and suspension. Below is a detailed introduction to the running system of wheeled vehicles: 1. Frame: The frame is a bridge-like structure that connects various axles and serves as the installation foundation for the entire vehicle. Its function is to mount the vehicle's assemblies and components, ensuring they maintain correct relative positions, and to withstand various static and dynamic loads from the vehicle and the ground. 2. Axle: The axle transmits forces in all directions between the frame (or the load-bearing body) and the wheels. Axles are categorized into four types: steering axle, drive axle, steering drive axle, and support axle. The steering axle allows the front wheels to pivot at certain angles for steering, while also bearing vertical loads, longitudinal and lateral forces from road conditions and braking, and the moments generated by these forces. 3. Wheels: Wheels are rotating components with tires mounted externally and axles at the center, designed to bear loads. They consist of the hub, rim, and spokes. Wheels are mainly divided into disc-type and spoke-type. Their functions include supporting the total mass of the vehicle and cargo; ensuring good adhesion between the wheels and the road surface to enhance traction, braking, and off-road capability; working with the vehicle suspension to reduce impacts during driving and mitigate resulting vibrations, ensuring a comfortable and smooth ride. 4. Suspension: The vehicle suspension refers to all power-transmitting connecting devices between the frame and the axle. It elastically connects the axle to the body, cushioning impacts from uneven road surfaces to ensure passenger comfort and cargo safety; quickly dampening vibrations caused by the elastic system; transmitting vertical, longitudinal, and lateral reaction forces and their moments; and guiding the wheels to move along a specific trajectory relative to the body.

What is the Difference Between a Beihu Car and a Mortgage Car?

The differences between a Beihu car and a mortgage car: 1. No transfer of ownership: A "Beihu car" refers to a vehicle that cannot be transferred to another owner. The difference between it and other types of cars such as "mortgage cars," "stolen cars," or "cars with excessive violations" is that a "Beihu car" is a completely normal vehicle with all necessary documentation, normal annual inspections, and insurance, but it just cannot be transferred to another owner. 2. Contract transfer: A mortgage car is a type of creditor's rights transfer under contract law. "Creditor's rights transfer," also known as "assignment of claims," refers to the transfer of a contract without changing its content. The creditor transfers all or part of the creditor's rights to a third party through a contract. Article 79 of the Contract Law of the People's Republic of China stipulates that after the creditor's rights transfer takes effect, the debtor and creditor may agree that a third party will perform the debtor's obligations instead. Creditor's rights transfer is protected by national law, and mortgage cars are part of the creditor's rights transfer law. 3. Price: Since a "Beihu car" cannot be transferred to the buyer's name, its price is naturally much lower than that of a normal transferable car. Generally, those sold with a complete set of documents, including the registration certificate, vehicle license, insurance, and a copy of the owner's ID card, will not have financial disputes. You only need to check the vehicle's current records (those in the used car business know how to retrieve records, requiring only the license plate number). Buyers should also pay attention to the authenticity of the records, as nowadays, a set of documents that look exactly like the real ones can be made for just five or six hundred yuan, making it difficult for ordinary people to distinguish between genuine and fake.
