Tire sidewall damage can be repaired depending on the actual situation, and each case should be judged individually. If the cord layer is not damaged, it can be repaired without increasing the risk of a blowout. However, if more than three cords in the tire sidewall are broken, repair is not recommended as it may affect driving safety. Below is relevant information about car tires: 1. Structure: Modern car tires are primarily radial tires, mainly composed of the cord layer and rubber. The cord layer consists of horizontal and vertical cords (some may include steel mesh), primarily serving a load-bearing function, while the rubber mainly provides sealing and flexible deformation capabilities. 2. Repair Principle: If the tire cord layer is damaged, it directly affects the tire's strength. The more cords that are broken, the greater the risk of a blowout. Similarly, if the inner cords of the tire are not punctured, the tire can still be used normally after restoring airtightness.

What is the alternative name for the car handbrake lever?

Handbrake is also called the parking brake lever. The parking brake lever is an operating device that fixes the car body on the ground or a certain plane without relative movement, and it is part of the car parking brake assembly. The following is a detailed introduction about car brakes: 1. Brake: Brake, also known as deceleration, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transportation tools or machinery. The braking device is a mechanical braking device that can slow down the speed, also known as a decelerator. 2. Braking system: The braking system consists of a control system, a hydraulic system, and a power assist system. The control system includes pedals, handbrakes, etc. The hydraulic system consists of hydraulic oil, brake pumps, and hydraulic oil pipes. The power assist system is the vacuum booster pump. The electronic control system consists of ABS pumps, ABS sensors, and ABS computers. The execution system consists of brake calipers, brake pads, and brake discs.

How to Replace a Car Oil Filter?

Method for replacing a car oil filter: 1. Remove the engine guard plate, place an oil drain pan under the drain bolt, loosen the drain bolt with an appropriate wrench, and when most of the oil has drained, loosen the oil filter. 2. After the oil has completely drained, reinstall the oil filter and drain bolt, ensuring there are no leaks around the edges of the oil filter or near the drain bolt, and finally reinstall the engine guard plate. Here is some relevant information: 1. When removing the oil filter, apply force at the lower end of the oil filter. This way, even if the filter is squeezed and deformed, it won't affect the internal filter screen. Applying force in the middle may damage the filter screen if deformed. Never use an adjustable wrench to remove the oil pan bolt, as it can easily strip the bolt. Loosening the oil cap before draining the oil will allow the old oil to flow more smoothly. 2. When tightening the oil pan bolt, be mindful of the force—just tighten it sufficiently to avoid stripping the threads. Some oil pan bolts have copper washers to prevent leaks, which need to be replaced periodically. Dispose of the old oil properly and avoid dumping it carelessly to prevent environmental pollution. If you can't find a disposal location, store it in a used oil container and take it to a repair shop for proper disposal.

How to Repair Worn Leather Seats?

Clean with a soft brush, then dry with a towel. Sand the surface to be repaired with water sandpaper, then apply a leather repair paste in the order of "fill-sand-fill-sand," and finally color it. After wiping the car leather seats thoroughly with a damp cloth, apply foam cleaner to the entire surface of the leather seats. Let it sit for a few minutes, then gently wipe off the foam cleaner with a soft cloth. Make sure to wipe clean without leaving any residue. Once the leather seats are cleaned, spray leather conditioner on the surface and use a clean, soft cloth to spread it evenly over the entire leather surface. Maintenance of leather seats: 1. Proper cleaning: Cleaning leather seats is essential. When cleaning car leather seats, use a suitable cleaner to remove dust and stains from the leather surface, preventing bacteria and pollutants from damaging the leather and keeping it dry and tidy. 2. Avoid soaking: Some owners may be lazy and soak the seats directly, which can cause significant damage to the leather. 3. Keep away from heat sources: Placing hot objects near leather seats can cause the leather to crack, turning a once-pristine seat into an eyesore. Also, avoid exposing leather seats to direct sunlight to prevent fading. 4. Smart conditioning: Properly conditioning the leather with fat can nourish it, repair damage, and make the surface smoother and more even, resulting in a softer and smoother feel.

What is the general width of a car in millimeters?

Car widths typically range between 1600mm and 2000mm. Generally, the front wheel arches mark the widest point of a car, with the recognized maximum width being 2 meters. Width primarily affects seating space and maneuverability. For passenger vehicles, if three seats are to be arranged side by side with sufficient width, the car's width usually needs to reach 1.8m. The Japanese government imposes stricter limits on car width, with most vehicles being under 1.8m, while European cars tend to have wider bodies. Additional information: The structure of a car body mainly includes the body shell (body-in-white), doors, windows, front sheet metal components, interior and exterior trim, body accessories, seats, as well as ventilation, heating, cooling, and air conditioning systems. For trucks and specialized vehicles, it also includes the cargo compartment and other equipment.

Where is the OBD interface located in the Santana?

The OBD interface of the Santana is located under the steering wheel, directly above the left foot, slightly towards the steering wheel shaft, and the pink connector is the OBD interface. OBD stands for On-Board Diagnostics, which translates to "on-board self-diagnostic system" in Chinese. This system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed the standard. If they do, it will immediately issue a warning. When a system malfunction occurs, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate, and the Powertrain Control Module (PCM) will store the fault information in memory. The fault code can be read from the PCM through a specific procedure. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. OBD monitors the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR, and other systems and components in real-time. Then, through various emission-related component information, it connects to the ECU [Electronic Control Unit, which can detect and analyze emission-related faults]. When an emission fault occurs, the ECU records the fault information and related codes, and issues a warning through the fault light to inform the driver. The ECU ensures access to and processing of fault information through a standard data interface.

How to Cancel the Alarm with a Spare Key?

Car spare keys deactivate the alarm because the vehicle was originally locked using a remote key, and when opened with a mechanical key—whether it's the primary or spare key—the car's computer system defaults to interpreting this as a forced entry, triggering the alarm. To stop the alarm, quickly power on the vehicle after opening the door, as the spare key contains an engine decoding chip that allows the car to be started at any time. Here is some relevant information: 1. The car's spare key is intended for emergency use. Under normal circumstances, it is advisable not to leave it inside the car, as this can easily attract thieves, posing significant risks to personal safety and vehicle security. It is also not recommended to carry the spare key with you out of fear of being unable to unlock the car, as this could lead to accidental loss. However, if you are traveling long distances, you should carry the spare key with you to avoid major inconveniences in case the primary key is lost or becomes unusable. 2. A car alarm is a security device installed in the vehicle. If someone hits, impacts, or moves the car, the sensor sends a signal to the controller, indicating the intensity of the vibration. The system can then trigger a warning sound or a full alarm based on the vibration intensity, deterring thieves and alerting the owner. It is a multifunctional product that, in addition to its anti-theft alarm function, can also remotely open the trunk, lock/unlock doors, control windows, and even start the engine.
