How many liters of antifreeze should be added to a car's radiator?

A car generally requires about 4 liters of antifreeze. Antifreeze prevents the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. How to choose antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. In the market, antifreeze comes in specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. Can antifreeze be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned.

Is It Normal for Engine Oil to Reach the Upper Line When the Engine Is Cold?

When the engine is cold, it is relatively normal for the engine oil level to reach the upper marking line. The dipstick has two lines, one labeled 'min' and the other 'max,' representing the minimum and maximum levels. When adding engine oil, it is sufficient to maintain the oil level between the minimum and maximum marks, avoiding exceeding the maximum or falling below the minimum. Additional Information: 1. When the engine oil level is below the minimum mark, the engine may experience poor lubrication. If the oil level exceeds the maximum mark, the internal operating resistance of the engine may increase, leading to higher fuel consumption and slower throttle response. To check the oil level accurately, ensure the engine is cold. After driving, allow the vehicle to cool down before checking. If checked immediately after driving, the oil may still be distributed throughout the engine and not fully returned to the oil pan, resulting in an inaccurate reading. 2. If the oil level is too low, it may cause a drop in oil pressure, triggering the oil pressure warning light on the dashboard. Similarly, insufficient oil viscosity can also lead to low oil pressure, activating the warning light. When adding oil, it is recommended to use fully synthetic oil, as it lasts longer and provides better lubrication for the engine. Fully synthetic oil is artificially synthesized, resulting in more uniform molecular size and shape.

What does an engine displacement of 1598ml mean?

"A displacement of 1598ml means the engine has a displacement of 1.598L. Displacement is a crucial structural parameter that comprehensively measures the size of an engine. The performance indicators of an engine are closely related to its displacement. Generally, the larger the engine displacement, the higher the power output. Displacement per unit is often used as a basis for comparing the sizes of different engines. Introduction to engine displacement: Engine displacement is one of the most important structural parameters. It more accurately represents the size of an engine than the bore diameter and the number of cylinders. Many performance indicators of an engine are closely tied to its displacement. Typically, a larger displacement means the engine can release more energy per unit time, resulting in better power performance. Engine maintenance methods: Regular oil changes: The oil must match the vehicle model. Regular coolant replacement: Coolant helps to cool down the engine. Clean the fuel system: The fuel system can accumulate impurities and should be cleaned periodically. Replace the oil filter: The oil filter acts as a screen, effectively filtering out impurities and preventing particles from entering the engine. Clean or replace it when it gets dirty or damaged to help extend the engine's lifespan."

What are the requirements for fire extinguishers during annual vehicle inspections?

There are specific requirements for in-vehicle fire extinguishers during annual vehicle inspections, as follows: Within the validity period: Used fire extinguishers must be sent to maintenance units with fire extinguisher repair licenses for inspection, refilling of extinguishing agents, and propellant gases. Regardless of whether they have been used, fire extinguishers must undergo maintenance when they exceed the manufacturer's validity period. Passing hydrostatic pressure tests: In-vehicle fire extinguishers must undergo hydrostatic pressure tests every two years and can only continue to be stored in the vehicle after passing the tests. No deformation in the cylinder: The exterior of the in-vehicle fire extinguisher must be inspected to ensure there is no rust or deformation. Additionally, the nozzle should be checked for deformation, cracks, or damage. In-vehicle fire extinguishers are specifically designed for car fires and come in two main types: non-pressurized suspension-type ultra-fine dry powder automatic fire extinguishing devices for vehicles and pressurized suspension-type ultra-fine dry powder automatic fire extinguishing devices for compact cars. During annual vehicle inspections, a fire extinguisher must be placed inside the vehicle; otherwise, the inspection cannot be passed.
