Do not fill the car radiator to the top. The water level should be between the highest and lowest marks on the radiator. Here is more information about the car radiator: 1. Introduction: The car radiator, also known as the heat exchanger, is a key component of the car's cooling system and part of the car engine. 2. Function: Its purpose is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, thereby regulating the temperature. 3. Working Principle: When the engine's water temperature is high, the water pump circulates the water repeatedly to lower the engine's temperature and protect the engine. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from becoming too cold.

Can Blackened Taillights Pass the Annual Inspection?

Blackened taillights cannot pass the annual inspection. The annual vehicle inspection is a mandatory test for all vehicles with official license plates and registration certificates. If the vehicle's headlights are modified without approval from the traffic management department, the vehicle will fail the inspection. Therefore, blackened taillights without approval will affect the annual inspection. Blackened taillights are achieved by applying a film to the taillights. The steps for applying the film are as follows: 1. Use a spray bottle to lightly spray water on the taillight, just enough to form small droplets, then take out the film. After peeling off the film, also spray some water on it, just enough to form small droplets, and slowly place it on the taillight. 2. Use a tool to gradually smooth the film on the taillight. Stop when you reach a point where folds might appear, then use a heat gun on a low setting to evenly heat the area until the folds disappear. Continue smoothing the film with a squeegee.

What is the Difference Between Energy-Efficient Vehicles and New Energy Vehicles?

Energy-efficient vehicles and new energy vehicles differ in their definitions: Energy-efficient vehicles refer to those with internal combustion engines as the primary power system, achieving fuel consumption that surpasses the target value for the next phase of vehicles under comprehensive operating conditions; new energy vehicles refer to those that utilize unconventional automotive fuels as power sources (or use conventional automotive fuels with the introduction of new automotive power devices), integrating advanced automotive power control and drive technologies to form advanced technical principles, resulting in vehicles with new technologies and structures. Relevant information about energy-efficient vehicles and new energy vehicles is as follows: 1. Energy-efficient vehicles refer to low-energy-consumption, low-pollution, small-displacement, new-energy, and new-power vehicles. 2. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy (such as supercapacitors, flywheels, and other high-efficiency energy storage devices) vehicles.

At how many kilometers should the second maintenance be performed for the National VI 1.4 Sagitar?

The second maintenance for the National VI 1.4 Sagitar should be performed at 15,000 kilometers or half a year after the first maintenance, whichever comes first. The maintenance cycle for the Volkswagen Sagitar: According to the official manual from FAW-Volkswagen, the first free maintenance should be performed within one year from the date of purchase or when the vehicle reaches 7,500 km (no more than 10,000 km). The second maintenance should be performed at 15,000 km at a 4S store, after which regular maintenance is required every 15,000 km or once a year. Maintenance items for the Volkswagen Sagitar: Engine oil, oil filter, air filter, and brake fluid should be replaced every two years. Spark plugs should be replaced every 30,000 km, and the air filter element, cabin air filter, and fuel filter should be replaced every 30,000 km or two years. The transmission fluid should be inspected every 60,000 km or four years and replaced if necessary.

What does intermittent braking mean?

Intermittent braking refers to pressing the brake pedal slightly first. When the vehicle noticeably decelerates, release the brake (not completely), and when you feel the braking effect is about to diminish, press the brake again. This repeated cycle is what is known as "intermittent braking." "Intermittent braking" was commonly used for large vehicles without ABS and equipped with air brakes. Below is relevant information: 1. Applicable objects of intermittent braking: Mostly used for large vehicles without ABS and equipped with air brakes in the past. However, the intermittent braking method can affect the smoothness and comfort of the vehicle's movement. Small cars are lightweight, and unless it's a prolonged downhill descent, the wheel hubs won't overheat excessively. It is not recommended to use intermittent braking for deceleration in small cars. 2. Reason for using intermittent braking: Because large vehicles are heavier, and air brakes respond faster than hydraulic brakes, intermittent braking is employed to avoid fully locking the brakes, preventing the wheels from locking up and losing steering control. 3. The purpose of intermittent braking is: To prevent wheel lockup, thereby controlling the vehicle to avoid skidding.

When Will the Official License Plate Be Issued?

Official license plates are generally issued within three to five working days. Below are the detailed steps: 1. Before registering a new vehicle, you need to prepare the vehicle qualification certificate, keep the triplicate invoice for the car purchase, pay the vehicle purchase tax and obtain the tax payment certificate, prepare copies and originals of your ID card, go to the vehicle management office for registration and inspection, and then select the license plate number. 2. After waiting for 5 working days, you can receive the license plate, either by picking it up at the vehicle management office or having it delivered to your home via express mail. Here is some additional information: 1. Introduction: License plates, commonly known as vehicle plates, refer to the plates hung on the front and rear of a vehicle. They are usually made of aluminum, iron, plastic, or paper, and display the vehicle's registration number, registration region, or other relevant information. 2. Function: License plates serve as a numbering and information registration system for vehicles. Their main purpose is to identify the region to which the vehicle belongs and to trace the vehicle's owner and registration details based on the plate number.
