What documents are required for 2021 vehicle annual inspection?

For the 2021 vehicle annual inspection, you need to bring the original vehicle license, duplicate of compulsory traffic insurance, and a copy of your ID card. Notes for annual inspection: During the inspection, the vehicle management office will check the vehicle's lights. If the lights are found to be too dim or too bright, the vehicle will be deemed unqualified and will not pass the inspection. If the lights are too dim, check the lighting circuit and whether the bulbs are aged, replacing relevant parts if necessary. If xenon headlights have been installed, it is recommended to restore the original headlights before the inspection to pass the test. Annual inspection procedure: First, after submitting the inspection application, an online inspection will be conducted. Drive the vehicle into the automatic inspection area to sequentially check whether the exhaust, speed, lights, side slip, and chassis meet the standards. All items must pass to proceed. Next is the appearance inspection, verifying the vehicle's license plate, type, body color, engine number, VIN code, and frame number for accuracy. Then inspect the body appearance, checking details such as the bumper, engine compartment, rearview mirrors, lower mirrors, window glass, paint, engine operation status, and the interior and wheels of passenger vehicles. Finally, the owner can obtain the inspection report and application form from the inspector. If all items pass, you can proceed to pay the inspection fee and collect the vehicle license and certification label. If any items fail, the owner must repair them and participate in a re-inspection until all items pass before proceeding with the visa procedures.

What Causes the Paint Surface to Appear Hazy and Dull After Polishing?

This layer of white haze may be caused by not promptly wiping off the polishing wax with a cloth after polishing. You can try using wax and a damp cloth to see if it can be wiped off. If that doesn't work, it is recommended to visit a 4S store for professional polishing by a technician. Here is some additional information: 1. Other causes of haze: The construction process and environment may have excessive humidity, or there may be moisture in the air compressor. If the environmental humidity is too high, a small amount (not exceeding 15%) of white water can be added for spraying. Ensure all moisture is drained from the compressor before spraying. The use of inappropriate thinners that evaporate too quickly can cause the surface temperature of the paint film to drop sharply, leading to moisture condensation on the film. 2. Prevention methods for whitening, hazing, and blurring after painting: Whenever possible, avoid painting in rainy, cold, or humid weather and allow the paint film to dry naturally. Otherwise, use a non-hazing thinner. Use high-quality thinners or thinners of the appropriate grade. Reduce the pressure of the compressed air to minimize the cooling effect, ensure proper ventilation and heating in the painting room, and avoid drafts.

Is It Serious If a Car Is Flooded Up to the Foot Mats?

If the car is flooded up to the foot mats, it is quite serious. It is recommended that the owner take the car to a professional auto repair shop for thorough cleaning and drying. The following two flood heights can help determine whether the car can continue to be driven: 1. Exhaust Pipe Height: Many car owners worry that water reaching the exhaust pipe will backflow. In fact, the pressure generated by the engine during exhaust is very high, enough to expel any water that backflows into the exhaust pipe. Therefore, as long as the car does not stall and maintains sufficient and stable power, it can prevent water from backflowing into the exhaust pipe and safely pass through flooded areas. 2. Half-Wheel Height: Cars are equipped with various electronic components and sensors. If water enters the interior, it is highly likely to damage these electronic components or sensors.

What is the difference between an intercooler and a radiator?

The differences between an intercooler and a radiator are as follows: 1. Essential difference: The intercooler is actually an accessory for turbocharging, whose function is to reduce the temperature of the high-temperature air after pressurization, thereby reducing the thermal load on the engine, increasing the intake volume, and consequently enhancing the engine's power. For turbocharged engines, the intercooler is a crucial component of the turbocharging system. The radiator, on the other hand, is an important component in hot water (or steam) heating systems. 2. Different classifications: Intercoolers are generally made of aluminum alloy materials. Depending on the cooling medium, common intercoolers can be divided into two types: air-cooled and water-cooled. Radiators are classified by heat exchange method into radiant radiators and convective radiators.

Does a mortgaged car have a green book?

When buying a car on mortgage, there is a green book, which is usually obtained when registering the vehicle at the vehicle management office. Here are the relevant details: 1. Introduction to the green book: Since purchasing a car with a loan involves borrowing funds from a lending institution, the green book will be temporarily held by the lending institution and can only be retrieved after the loan is fully repaid. 2. Vehicle license: The vehicle license, also known as the motor vehicle license, is the legal document permitting the vehicle to drive on roads within China. It is an important document recognized by Chinese laws and regulations, playing a significant role. Drivers must highly value it to protect their legal rights. The motor vehicle license in the driver's possession contains detailed information, including the license plate number, owner's name, model type, engine number, chassis number, load capacity or passenger capacity, initial registration date, and annual inspection records. The motor vehicle license is unique, meaning for a specific vehicle, there is only one set of engine and chassis numbers.

How to Prevent Rolling Back When Starting on a Slope?

The reasons for rolling back when starting on a slope generally fall into two categories: 1. The handbrake is not fully engaged: When parking on a slope, if the handbrake is applied but not tightened sufficiently, releasing the foot brake can cause the vehicle to roll back. 2. Releasing the brake too early: If the clutch is not yet at the semi-engaged position and the brake is released prematurely, it will lead to rolling back. Methods to avoid rolling back when starting on a slope are as follows: 1. Place the gear lever in neutral, fully engage the handbrake to ensure the vehicle does not roll; 2. With the left foot, fully depress the clutch, shift into first gear, hold the steering wheel at the 9 o'clock position with the left hand, and hold the handbrake with the right hand; 3. Gradually release the clutch with the left foot until reaching the semi-engaged position. When the vehicle starts to vibrate and shows a tendency to move forward, begin to gently press the accelerator pedal with the right foot, and press the handbrake release button with the right hand; 4. Once the vehicle starts moving forward, completely release the handbrake with the right hand.
