The dashboard CH indicates the water temperature gauge. The water temperature ranges from C to H. C represents 60 degrees, and once the water temperature gauge pointer reaches C, it means the water temperature has reached 60 degrees. The red H mark represents 110 degrees, and the span from 60 to 110 degrees allows you to estimate the temperature indicated by the water temperature gauge. Generally, if the water temperature light on the dashboard stays on, it indicates a fault in the engine's cooling system. Common fault points include: 1. Insufficient coolant in the engine cooling system, which may be due to leaks in the engine, such as water pump leakage, pipe damage, or radiator damage. 2. A faulty thermostat in the engine cooling system causing the water temperature to rise too high. Because the thermostat cannot open, the flow of coolant inside the engine is obstructed, leading to excessively high coolant temperature.

What to Do If 12 Points Are Deducted from a Driver's License Within the First Year?

A driver's license that is less than one year old is considered to be in the probationary period. If a motor vehicle driver commits road traffic safety violations during this probationary period and accumulates 12 penalty points, the driving qualification for the probationary vehicle type will be revoked. Here are the main points to note during the probationary period: Special vehicles cannot be driven during the probationary period: During the probationary period, new drivers are not allowed to drive buses, commercial passenger vehicles, police cars, fire trucks, ambulances, engineering rescue vehicles, or vehicles carrying hazardous materials such as explosives, flammable and explosive chemicals, highly toxic substances, or radioactive materials. Additionally, the motor vehicle driven cannot tow a trailer. Cannot drive alone on highways during the probationary period: New drivers cannot drive alone on highways during the probationary period. They must be accompanied by a driver with at least three years of driving experience in the front passenger seat. The accompanying driver should provide guidance to the probationary driver. Failure to have a qualified accompanying driver or not meeting the requirements will result in a fine of 200 yuan. Must display a probationary sign: When driving during the probationary period, a standardized probationary sign issued by the traffic management department must be affixed or hung at the rear of the vehicle.

What is the fuel consumption of the Honda Jade?

20 Honda Jade fuel consumption is 6.9L per 100 kilometers. The factors affecting car fuel consumption are as follows: Engine displacement: Engine displacement has a certain impact on car fuel consumption, but this impact is a fixed value. Tire pressure: Car fuel consumption is also directly related to tire pressure. When the tire pressure is too high or too low, the car's fuel consumption will increase. Driving conditions: The road conditions on which the car is driven will also affect fuel consumption. The combined fuel consumption is calculated by dividing the total emissions of urban and suburban cycles by the total mileage completed in these two cycles, and then using the corresponding emissions to calculate the fuel consumption value.

Why is the BMW 530 reversing camera not displaying?

BMW 530 reversing camera may not display due to poor contact. Here are the specific reasons and solutions: 1. Specific reasons: Poor line contact causing intermittent connection, leading to abnormal reversing camera display; Aging of video power cable resulting in intermittent image display; Prolonged use of reversing camera causing poor chip photosensitivity, which not only produces snowflake effects but may also lead to black screen in severe cases. 2. Solutions: Reconnect the loose connection properly; Replace with a new power cable; Have it inspected and repaired at a maintenance shop or directly replace it.

What is the power output of the 4BD1 engine?

4BD1 engine has a power output of 75KW. Here are the specific details about engine power: 1. Advantages and disadvantages of high-power models: With the same displacement, the higher the power, the better. Some manufacturers use technologies such as intake valve stroke control, EGR, and 5-valve to increase power. High-power models will have higher fuel consumption and increased emissions pollution. 2. Concept: Engine power refers to how fast the engine does work. The engine's power is not equal to the vehicle's power, as there are intermediate losses in mechanical transmission. Designs that thicken and reinforce the body for safety considerations can also lead to a loss of engine power. Therefore, vehicles equipped with small-displacement engines are not necessarily slower or inferior in performance compared to those with high-power engines.

How Many Years Can a Sedan Be Used?

Small private cars have no usage time limit, but they will be scrapped after traveling 600,000 kilometers. The relevant introduction to mandatory scrapping is as follows: Mandatory scrapping age for cars: Small and micro taxi passenger cars are used for 8 years, medium taxi passenger cars for 10 years, large taxi passenger cars for 12 years, rental passenger cars for 15 years, small long-distance passenger cars for 10 years, medium long-distance passenger cars for 12 years, large long-distance passenger cars for 15 years, passenger cars for 13 years, other small and micro operational passenger cars for 10 years, and large and medium operational passenger cars for 15 years, and so on. Mandatory scrapping standards for cars: Reaching the legally prescribed usage period, still failing to meet the relevant requirements of the national safety technical standards for in-use motor vehicles after repair and adjustment, still failing to meet the relevant requirements of the national standards for in-use motor vehicles after repair and adjustment or the adoption of control technology, and emitting pollutants or noise into the atmosphere.

How Often Should Car Compressor Lubricant Be Changed?

Generally, car compressor lubricant should be changed every 5,000 kilometers or 7,500 kilometers. Relevant information is as follows: 1. Lubricant: The lubricant used in air compressors is a special compressor-specific oil provided by lubricant manufacturers. The lubricant has three functions: cooling compressed air, sealing rotor meshing gaps, and lubricating bearings, shaft seals, and gears. In fact, most of the oil is used to cool the compressed air. The oil that enters the compression chamber to cool the compressed air comes into direct contact with the air at operating temperatures of nearly 100 degrees, making it highly prone to oxidation and deterioration. Therefore, the cooling lubricant must have excellent oxidation resistance. 2. Formula: The lubricant used in air compressors is formulated with special additives, not only to fully perform the three functions of the lubricant but also to provide characteristics such as oxidation resistance, minimal foaming, and low air solubility. 3. Time: The interval for changing the lubricant depends on actual conditions. Generally, the lubricant must be changed after accumulating 2,000 hours of operation, but this also depends on the customer's usage patterns and frequency.
