Car always having high water temperature reasons are: 1. Thermostat damage, coolant only circulates in a small cycle without dissipating heat through the radiator; 2. Cooling fan not working, temperature control switch not opening or water temperature sensor failure; 3. Water pump failure, impeller slipping or jamming causing the belt to break; 4. Insufficient cooling medium, lack of coolant or radiator leakage; 5. Incorrect ignition timing and high oil pressure, water temperature gauge reading differs from actual temperature; 6. Radiator blockage, external dirt clogging, internal water channel blockage affecting coolant circulation; 7. Cylinder erosion, leading to frequent radiator water shortage.

Why Can't I File My Driver's License?

Most cases of unsuccessful filing are due to the driver's license information not being uploaded or updated in the vehicle management office system, or data delays, which prevent the traffic management system from detecting the new data. This is why vehicle management office staff recommend waiting three days before driving, not because the driver's license is unusable. Relevant information about the driver's license is as follows: 1. Introduction: The People's Republic of China Motor Vehicle Driver's License, commonly referred to as a driver's license or 'driver's permit,' is a mandatory certification for motor vehicle drivers under the laws of the People's Republic of China. 2. Examination Content: The test subjects include traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving).

What to Do with Two Beidou Cards in a Truck?

When two people drive the same truck, to avoid fatigue driving, if they forget to turn off the engine and switch cards during the driver change, it will not only cause the Beidou driver card to continue timing and be considered as fatigue driving, but also lead to a mismatch between the Beidou driver card information and the actual driver. This may result in corresponding penalties from traffic police, which is not worth the loss. Motor vehicle drivers committing any of the following violations will be penalized with 1 demerit point: 1. Driving a motor vehicle without using lights as required; 2. Driving a motor vehicle without proper meeting of vehicles as required; 3. Driving a motor vehicle with cargo exceeding the prescribed length, width, or height; 4. Driving a motor vehicle on the road without displaying the inspection qualification mark or insurance mark, or without carrying the vehicle license or motor vehicle driving license.

What Happens If a New Battery Is Not Fully Charged for the First Time?

Not fully charging a new battery for the first time will not have any significant impact. Below is an introduction to the voltage and current during battery charging: 1. Voltage: The charging voltage for motorcycles is 12V. During the charging process, the voltage typically ranges between 13.5-14.5V. When charged on the vehicle via the rectifier, it will not exceed 15V. If using a charger, the charging voltage is usually around 14V. 2. Current: The charging current for motorcycles should not be too high. It is recommended that vehicle owners avoid using fast charging. During charging, use a current that is half the rated charging current and extend the rated charging time by double.

How to Steer on Curves?

Methods for steering on curves: Turn the steering wheel to the left for left curves and to the right for right curves. Precautions for steering on curves: 1. Avoid excessive steering wheel rotation; 2. Reduce throttle in advance, apply brakes, slow down the speed, and observe both side mirrors. The functions of a car steering wheel include: audio control, hands-free calling, cruise control, and instrument data switching. The working principle of the steering wheel is: converting force into torque and transmitting it to the steering shaft. The correct way to hold the steering wheel is: imagine the steering wheel as a clock face, with the left hand at the nine o'clock position and the right hand at the three o'clock position, thumbs naturally pointing upwards and the other four fingers pointing downwards.
