Where to Add Radiator Coolant?

Radiator coolant is added to the car's expansion tank. Open the engine hood and locate the expansion tank, which is usually spherical in shape. Remove the tank cap and add the appropriate amount of radiator coolant. The optimal filling level is between the MAX and MIN marks. Here are some related details: 1. Replacement Cycle of Radiator Coolant: Radiator coolant is generally replaced every two years. 2. Radiator Coolant Should Not Be Mixed with Water: Adding water can affect the performance of the radiator coolant, lowering its boiling point and reducing its cooling effectiveness. It also raises the freezing point, making it prone to freezing in cold climates. Ordinary tap water contains various impurities and ions, which can form scale over time and cause blockages. In emergency situations, adding water may be unavoidable, but it is recommended to use purified water, preferably distilled water, and not to add too much. 3. Shelf Life of Radiator Coolant: When adding radiator coolant, always check the shelf life. Typically, radiator coolant has a shelf life of about two years. Expired products should not be used. Choose high-quality coolant that matches the original color of your car or a universal type. Different brands and colors of radiator coolant have varying formulations, and mixing them can cause reactions that reduce their effectiveness.

What is the fuel tank capacity of the Yidong Plus?

Yidong Plus has a fuel tank capacity of 53 liters, which is the officially announced data. Owners who have purchased the Yidong Plus can also check this information on the vehicle's configuration sheet. The Yidong Plus requires 92-octane gasoline, with a fuel consumption of 5.6-5.8L per 100 kilometers. A full tank can provide a driving range of approximately 914 to 946 kilometers. During daily driving, it is important to always monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments remaining to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the manufacturer is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How many people can a sedan carry?

According to the Road Traffic Safety Law, a sedan is generally designed to seat 5 people, including the driver. If the number exceeds 5 people including the driver, it is considered overloading. 1. Based on Article 2 of the "Scoring Standards for Road Traffic Safety Violations", if a motor vehicle driver commits any of the following violations, 6 points will be deducted: driving a commercial passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20%, or driving other passenger vehicles with passengers exceeding the approved capacity by more than 20%. 2. The following regulations shall be observed for motor vehicle passenger transportation: a. Road passenger vehicles shall not exceed the approved passenger capacity, except for children exempted from tickets as per regulations. When the passenger capacity is full, the number of exempted children shall not exceed 10% of the approved capacity; b. The cargo compartment of a truck shall not carry passengers. On urban roads, cargo motor vehicles may carry 1 to 5 temporary workers in the compartment if safety conditions are met; when the cargo height exceeds the compartment barrier, no person shall ride on the cargo; c. Children under 12 years old are not allowed to ride on the back seat of a motorcycle, and light motorcycles shall not carry passengers.

What documents are required for vehicle tax payment?

Before paying the purchase tax, the following materials need to be prepared: 1. Owner's identity proof: Mainland residents should provide an ID card, while residents from Hong Kong, Macao, Taiwan, and foreigners should provide entry permits and residence permits. Organizations should provide institutional code certificates. 2. Vehicle price proof: This is an important standard for levying purchase tax. Provide the "Unified Invoice for Motor Vehicle Sales". For imported vehicles, provide proof of customs duties and consumption tax. 3. Vehicle qualification proof: Additionally, provide other materials required by the tax authority. Other required materials are as follows: 1. For individual accounts: Original and photocopy of ID card (for both the owner and the agent). Original vehicle purchase tax payment application form. Original and photocopy of the motor vehicle qualification certificate. Photocopy of the first page of the unified invoice for motor vehicle sales. Photocopy of the fourth page of the unified invoice for motor vehicle sales. 2. For corporate accounts: Original and photocopy of the agent's ID card with the company seal. Photocopy of the business license with the company seal. Original vehicle purchase tax payment application form with the company seal. Original and photocopy of the motor vehicle qualification certificate. Original third page of the unified invoice for motor vehicle sales. Photocopy of the first page of the unified invoice for motor vehicle sales. Photocopy of the fourth page of the unified invoice for motor vehicle sales.

Where Does the Refrigerant Leak in a Car Air Conditioner Usually Occur?

Refrigerant leaks in car air conditioners typically occur at the joints of the air conditioning pipes, the expansion valve, the compressor, the evaporator, and other components. Below are detailed explanations of the causes of refrigerant leaks in car air conditioners: 1. Pipe failure. When laying the connecting pipes between the indoor and outdoor units of the air conditioner, if the bending angle of the pipes is too small, it can cause the pipes to crack and leak refrigerant or result in no refrigerant. When laying the connecting pipes between the indoor and outdoor units, the bending radius of the pipes should be appropriately increased to prevent the pipes from being bent too sharply. Leaking pipes should be promptly repaired or replaced. 2. Leak points in the refrigeration system. When replacing parts of the refrigeration system, if the parts are not installed tightly during secondary installation, leak points for refrigerant can develop in the pipes and the refrigeration system. Apply a moderately thick soapy water solution to the entire refrigeration system pipes and welded areas to check for leaks. The testing conditions require the refrigeration system to be filled with nitrogen or refrigerant. Pay close attention to areas with oil stains on the pipes, identify the leak points one by one, and repair or replace the parts based on the actual situation.

What is an engine?

An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines and steam engines), and electric motors. For example, internal combustion engines typically convert chemical energy into mechanical energy. Here is some related information: 1. Applications of engines: Engines can be used as power generation devices or refer to entire machines that include power units (e.g., gasoline engines, aircraft engines). 2. The birth of engines: The engine was first developed in the UK, so the concept of an engine originates from English. Its original meaning refers to "a mechanical device that generates power." 3. Classification of engines: Automotive engines can be divided into two main categories: gasoline engines and diesel engines. They share the same basic structure, consisting of two major mechanisms and five systems: the crankshaft-connecting rod mechanism, the valve train, the fuel supply system, the lubrication system, the cooling system, the ignition system, and the starting system. 4. How an engine works: An engine does not rotate on its own without reason; it requires an external force to provide the initial power, which is supplied by the engine's starting system. During normal operation, the engine's working cycle includes four piston strokes: intake, compression, power, and exhaust.
