The reasons for the decrease in water level in the radiator are: 1. Water pipe joints or the pipes themselves are leaking, requiring pipe replacement or reinforcement of the seal; 2. Cracks in the engine block, or an improperly sealed or damaged cylinder head gasket causing water leakage; 3. Damaged seals or sand holes in the oil cooler leading to water leakage; 4. A loose radiator cap; 5. Leakage in the heater radiator; 6. Leakage in the three-way connector. The radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function 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 in a continuous cycle, achieving the effect of heat dissipation and temperature regulation.

How many kilometers can an Accord travel on a full tank of gas?

An Accord can travel 700 to 800 kilometers on a full tank of gas, with a fuel tank capacity of 56L and a fuel consumption of 6L per 100 kilometers. The Accord is a mid-size car under GAC Honda. The Accord Comfort Edition has a maximum motor power of 143W and a maximum torque of 260 N·m, equipped with a CVT transmission. The body dimensions are 4906X1862X1449mm in length, width, and height. Factors affecting fuel consumption: Poor road conditions or uneven surfaces, driving in low gear for extended periods, can increase fuel consumption; using the trunk as storage increases the vehicle's weight, and the relationship between weight and fuel consumption is directly proportional. A 10% reduction in vehicle weight can lead to a corresponding percentage drop in fuel consumption; incorrect driving habits have the most significant impact on fuel consumption. During driving, especially in heavy traffic, at red lights, or when changing lanes, rapid acceleration and sudden braking are the most common issues.

What material is the Mingtu spark plug made of?

Mingtu spark plugs are made of platinum. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Under high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a 'breakdown' phenomenon. At this point, the gas forms a luminous body, known as a 'spark.' Along with the heat and expansion, a 'crackling' sound is also produced. The temperature of this electric spark can reach 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the engine combustion chamber.
