For the same vehicle, the frame number and the vehicle identification number are identical. More information about the vehicle frame number and vehicle identification number is as follows: 1. The frame number is a set of characters assigned by the manufacturer to identify a vehicle. 2. The vehicle identification number, also known as the VIN, consists of seventeen characters. The VIN is the car's ID card, and each vehicle's VIN is unique. This ensures that no two vehicles of the same model will have the same number within 30 years, providing a unique identifier for each vehicle. 3. The vehicle frame number can usually be found at the bottom of the car's windshield.

Last time my friend bought a used car, we talked about this topic. I told him that the Vehicle Identification Number (VIN) and the chassis number are actually the same thing—that 17-digit VIN code. It uniquely identifies your car and is printed on the lower right corner of the windshield or on the door pillar. Don’t worry too much, just jot it down. It’s especially useful when buying or selling a car, as you can check the car’s year, origin, and whether it’s been in any accidents. I recommend beginners take a photo and save it on their phone—it’s handy in case the car is lost or for repairs. Also, be careful during regular maintenance to avoid scratching it, as that could cause issues during registration. In short, think of it as the car’s ID card—just keep it simple.

In our line of work repairing cars for many years, the Vehicle Identification Number (VIN) and the chassis number are of course the same thing—it refers to the VIN code, which is fixed on the chassis. Every time a car comes in, the first thing we do is scan this code to confirm the model and ensure parts compatibility. Without it, diagnosing faults becomes much harder, especially in the used car market where vehicles with altered VINs pose significant risks. I've seen many car owners overlook this, leading to delays in repairs and even potential safety hazards. Therefore, regularly checking the car's frame and windows to keep the VIN clearly visible is a good habit that can save a lot of trouble.

What is the Beijing Hyundai Celesta?

Beijing Hyundai Celesta is the Hyundai Elantra. Below are the specific details about the Elantra: 1. The exterior of the Elantra belongs to the agile and compact type. The headlights and grille are designed to slope upwards, giving a sleek visual impression. The front end is composed of full curves and lines, making it look powerful yet stable. The wave-like lines on the side of the body are Hyundai's signature, with smooth body lines that give it a dynamic appearance. 2. In terms of interior design, the Hyundai Elantra features a very simple layout. The craftsmanship is standard, and the dashboard uses a lot of hard materials. It comes with a three-spoke multifunctional steering wheel, dual circular mechanical gauges, and a floating LCD screen. 3. In terms of performance, the Elantra is equipped with a 1.6L engine paired with a 6-speed automatic transmission, delivering a maximum output of 123 horsepower. The power output could be considered one of the few drawbacks of the Elantra. Of course, it's not necessarily a flaw, as this level of power is sufficient for various driving conditions. However, nowadays, small-displacement engines dominate the mid- and low-end car market, with 1.0T and 1.3T three-cylinder engines becoming increasingly common.

How often should the transmission fluid be changed for the New Sagitar 1.6?

The transmission fluid replacement interval for the Sagitar 1.6 is every 60,000 kilometers, with a replacement capacity of 4L. Volkswagen Sagitar transmission fluid replacement methods: 1. Gravity replacement: The method and principle are the same as for engine oil. Using tools to loosen the nut, the transmission fluid will automatically flow out under gravity. This method is the most common and easy to operate, but it cannot completely drain the old transmission fluid. Dirty old transmission fluid may remain in mechanical depressions and dead corners. 2. Circulation machine replacement: New transmission fluid is added to the circulation machine, and the machine's pipes are connected to the transmission's oil lines. The new fluid pushes out the old fluid under the action of the circulation machine. This method cleans the oil lines more thoroughly. The more new transmission fluid used in the circulation machine, the cleaner the old fluid will be discharged. This method typically uses about 10-15L of fluid per replacement and takes approximately 1 hour. 3. Oil pan removal replacement: This method allows for cleaning the oil filter and flushing the oil pan, addressing the issue at its root. Removing the oil pan is a significant task, and the corresponding labor cost will be higher.

How to Open the Bonnet of the Binyue?

There is an unlock button in the control area on the left side of the steering wheel. Press it to pop up the bonnet, then reach in and pull the latch to open it. Below are the specific functions of the bonnet: 1. Airflow guidance. For objects moving at high speed in the air, the air resistance and turbulence generated by the airflow around the moving object directly affect its trajectory and speed. The shape of the bonnet can effectively adjust the direction of the airflow relative to the car's movement and the resistance force, reducing the impact of airflow on the car. 2. Protection for the engine and surrounding components. Under the bonnet are crucial parts of the car, including the engine, electrical circuits, fuel lines, braking system, and transmission system, all of which are vital to the vehicle. By enhancing the strength and structure of the bonnet, it can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the normal operation of the vehicle. 3. Aesthetics. The exterior design of a vehicle is a direct reflection of its value. As an important part of the overall appearance, the bonnet plays a critical role in enhancing visual appeal and embodying the concept of the entire car. 4. Assisting driver visibility. During driving, the driver's ability to correctly judge road conditions and the situation ahead heavily relies on the reflection of natural light and the view ahead. The shape of the bonnet can effectively adjust the direction and form of reflected light, thereby reducing the impact of light on the driver.

How to Turn on the Low Beam Headlights of Haval H6?

To use the low beam headlights of Haval H6, first turn on the headlight switch, then rotate the light switch knob to the low beam position. The following are specific introductions to the high and low beam headlights: 1. The lower limit position of the low beam headlights does not need to be too precise, as long as you can clearly see the road about 20 meters ahead. 2. The high beam headlights can be turned on by pushing the lever outward, but there is a prerequisite for turning on the high beam: the low beam headlights must be on. The high beam cannot be turned on when the light is in other positions (off or position lights). However, pulling the lever inward to flash the high beam once has no restrictions and can be operated even when the lights are off. 3. The headlights have two modes: high beam and low beam. Use low beam on urban roads with streetlights and high beam on roads without streetlights or highways. When passing intersections or overtaking, alternately switch between high and low beams to signal. The position lights, commonly known as "small lights," are used to display the width and length of the vehicle at night, alerting other vehicles and pedestrians to your presence. When you cannot see clearly behind you in the rearview mirror, it's time to turn on the small lights, including during rainy days.
