The symptoms of a faulty tensioner pulley mainly include: 1. The engine will experience timing chain skipping; 2. Disordered ignition and valve timing; 3. Engine shaking and difficulty in ignition; 4. Severe cases may result in failure to start the car; 5. After starting, the valve may be deformed. Additional information: 1. The tensioner pulley is a belt tensioning device used in the automotive transmission system. It mainly consists of a fixed housing, tensioning arm, wheel body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the different tightness of the belt, ensuring the stability, safety, and reliability of the transmission system. 2. The tensioner pulley is a wear-prone part in automotive components. Over time, the belt can easily stretch. Some tensioner pulleys can automatically adjust the belt tension. Additionally, the tensioner pulley makes the belt run more smoothly, reduces noise, and prevents slipping.

What are the symptoms of a blown fuse in a motorcycle?

When a motorcycle's fuse blows, it generally causes a complete loss of electrical power in the entire vehicle. Here are the reasons for a blown fuse in a motorcycle: 1. Excessive load on electrical appliances or a short circuit occurs. First, disconnect all wiring related to the xenon headlights and check all connected circuits for grounding or short circuits. Then test ride the motorcycle. If the fuse doesn't blow, it indicates that the xenon headlights themselves are faulty or improperly wired. 2. A faulty rectifier can cause intermittent short circuits due to vibration and bumping during riding, leading to a blown fuse. 3. Short circuits in the wiring of electrical appliances can occur intermittently due to vibration and bumping during riding, resulting in a blown fuse.

How Long Does It Take to Repair a Bumper?

Bumper repair and repainting can take as little as one day or up to two days, depending on the drying time after painting and subsequent polishing. For an old bumper, the duration depends on the area to be repainted—small areas may take half a day, while larger areas require color matching with the rest of the vehicle to avoid noticeable differences. Non-original paint may result in a dull appearance compared to a new, shiny bumper. Below is relevant information: Bumper: The car bumper is a safety device designed to absorb and mitigate external impacts, protecting the front and rear of the vehicle. Impact of repainting on the vehicle: There are two main effects. First, large-scale repainting can affect the vehicle's resale value—for example, under similar conditions, a repainted car may be cheaper than one with minor scratches left untouched. Second, repainted surfaces age faster than the original factory paint because repair paint is not as durable as the original. Even if color differences are not immediately visible, they may appear over time, and in severe cases, the paint may even peel off.

Does insurance claim settlement look at the VIN or license plate number?

Insurance claim settlement checks both the VIN and license plate number. Below is relevant information about vehicle maintenance records: VIN: The Vehicle Identification Number, abbreviated as VIN, is a unique set of seventeen letters or numbers used on automobiles to identify the manufacturer, engine, chassis number, and other specifications. To avoid confusion with the numbers 1, 0, and 9, the letters "I", "O", and "Q" are not used, and the 10th digit representing the model year does not use "I", "O", "Q", "U", "Z", or "0". License plate number: The license plate number is the identifier for a vehicle's identity, much like an ID number for a person. For example, a car with a license plate from Guangzhou, Guangdong Province would have "Yue" representing Guangdong Province, "A" representing Guangzhou, thus "Yue A" would be the license plate code for Guangzhou.

What is the black plastic panel under the bumper called?

The plastic panel under the front bumper is called a deflector. The deflector is fixed under the bumper with screws or clips and can be removed by the user. The main function of the deflector on the car is to reduce the resistance during high-speed driving and lower the vehicle's fuel consumption. Material of the deflector: Originally, the deflector was a safety feature of the car, made of thick steel plates or metal. However, as cars evolved, aesthetics and lightweight became increasingly important, leading to its gradual replacement with plastic. Plastic is easy to shape but also prone to deformation, so it is important to protect the deflector. Function of the deflector: To reduce the lift generated when a car is driving at high speed, car designers not only improved the car's exterior but also installed a downward-sloping connecting panel under the front bumper. The connecting panel is integrated with the front skirt of the car body, with suitable air inlets in the middle to increase airflow and reduce the air pressure under the car.

Do I still need to display the insurance and annual inspection stickers in 2021?

2021 insurance and annual inspection stickers do not need to be displayed. The latest policy combines the vehicle annual inspection with the environmental protection inspection mark. As long as the vehicle passes the annual inspection, there is no need to obtain the environmental protection mark separately. Starting from June 2020, China has implemented electronic annual inspection marks nationwide. Now, when vehicle owners go for their annual vehicle inspection, they will no longer receive a paper annual inspection mark upon passing the inspection. Instead, they can directly obtain the electronic annual inspection mark through the traffic management app. Here are some important notes: Accident liability: For any traffic accidents caused by vehicles that have not undergone the annual inspection on time, the responsible party will bear full or primary liability, and the insurance company will not assume any responsibility. This is because the insurance policy specifies that vehicles with expired inspections are among the objects of claim rejection. Mandatory scrapping: According to the "Regulations on the Compulsory Scrapping Standards for Motor Vehicles", if a motor vehicle fails to obtain the inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection validity period, it will be compulsorily scrapped.
