What Causes the Engine Temperature to Rise During Normal Driving?

1 Answers

Normal driving with rising engine temperature can be caused by the following reasons: Low coolant level in the radiator. The engine relies on water cooling to lower its temperature. Although the coolant in the radiator depletes slowly, it still diminishes over time. Some car owners neglect to check the coolant level, leading to prolonged low levels and consequently high engine temperature. In such cases, the radiator needs to be refilled. Thermostat malfunction. Some drivers notice the engine temperature rising after just a few kilometers of driving, without any visible leaks in the hoses. This issue may stem from a thermostat that fails to open, preventing the car's cooling system from engaging in a full circulation cycle and causing high engine temperature. Replacing the thermostat is necessary here. Leaking hoses. If a leak is detected while driving, inspect whether the hoses are aged or cracked. This issue is relatively easier to identify, and the solution involves replacing the affected hoses at a repair shop. Poor radiator cooling. Some car owners use plain water as coolant. Prolonged use of water can lead to rust formation in the engine and radiator, impairing the radiator's cooling efficiency and resulting in high engine temperature. To resolve this, the rust must be removed first, followed by cleaning or replacing the radiator.

What is the 12123 Study to Reduce Points?

Study to Reduce Points related information is as follows: 1. Concept of Study to Reduce Points: Study to Reduce Points is for drivers holding a driver's license who have been penalized with points due to traffic violations. By participating in online traffic safety learning and passing the exam, they can have their points reduced. 2. Online Learning: To apply for 'Study to Reduce Points' online learning, continuous study for at least 5 minutes is required, which counts towards cumulative learning time. Accumulating 30 minutes of study within 3 days counts as one session. After meeting the learning time requirement, you can apply to take the online exam within 7 working days. If the exam is not passed, a make-up exam can be taken within 24 hours, with a limit of 2 make-up attempts. 3. Exam Method: The exam randomly selects 20 questions from a question bank, with a maximum of 60 seconds to answer each question. Accumulating 3 wrong answers or unanswered questions due to timeout results in exam failure and exit from the exam. On-site learning must last at least 1 hour each time, followed by an exam. 4. Reduction Rules: After receiving traffic safety education as required, eligible drivers can have points deducted from their existing accumulated points, with a maximum reduction of 6 points. However, this cannot be used to reduce points for traffic violations that have not yet occurred. Passing the online learning and exam reduces 1 point per session; passing on-site learning and exam reduces 2 points per session; participating in traffic safety public activities reduces 1 point per session.

Can a C2 license drive a semi-automatic car?

C2 license holders can drive semi-automatic cars because semi-automatic refers to automatic transmission vehicles, which fall within the permissible driving scope of a C2 license. Therefore, according to driving license regulations, C2 license holders are allowed to operate semi-automatic cars. Automatic transmission vehicles do not require gear shifting during driving, whereas manual transmission vehicles need timely gear changes to adjust vehicle speed and engine torque variations. In addition to automatic transmission cars, C2 license holders can also drive small and micro automatic transmission passenger vehicles, as well as light and micro automatic transmission cargo vehicles. Vehicles that cannot be driven with a C2 license: Large vehicles, such as those with more than nine seats or with a body length significantly exceeding six meters, cannot be driven with a C2 license. Additionally, even if the vehicle has fewer than nine seats and a body length under six meters, it cannot be driven if it has a manual transmission. Driving such vehicles without the proper license is considered unlicensed driving and may result in penalties such as fines and demerit points if caught. Type of semi-automatic cars: Semi-automatic cars belong to the automatic transmission category. They are equipped with a semi-automatic accelerator, which differs from the accelerator in manual transmission vehicles. The semi-automatic accelerator can only be used for acceleration or deceleration and does not allow gear selection, whereas manual transmission vehicles enable free gear selection in conjunction with clutch operation for skilled and flexible driving. Moreover, semi-automatic cars do not have a clutch pedal, meaning there is no clutch operation involved, confirming that semi-automatic cars are automatic transmission vehicles.

Within how many days should I register my car after a color change?

After applying a wrap at a certified modification shop, the shop will provide the owner with a receipt or invoice. The owner can register the change at the vehicle management office within 10 days from the date the invoice is issued. According to Article 56 of the "Regulations on the Registration of Motor Vehicles," if the vehicle's color is changed without registering the modification as required, the traffic management department of the public security authority may issue a warning or impose a fine. The vehicle may also be impounded and required to be restored to its original color. To apply for a change in the vehicle's body color, the following documents must be submitted in accordance with the "Road Traffic Safety Law": "Application Form for Modification Registration of Motor Vehicles," identity proof of the vehicle owner and their agent, the motor vehicle registration certificate, and the motor vehicle driving license. According to Article 6, Chapter 2 of the "Road Traffic Safety Law," if the area of color change does not exceed 30% of the vehicle's surface, no modification registration is required. Conversely, if it exceeds 30%, the change must be registered, and the registration must be completed within 10 days after the color change. Important considerations for vehicle color changes: Before changing the vehicle's color, consult the local vehicle management office where the vehicle is registered to confirm whether the area permits changing the vehicle's color using wraps. If the region does not support this method, the modification cannot be registered, and the wrap must be completely removed to restore the vehicle's original color. Additionally, according to the "Regulations on the Registration of Motor Vehicles," owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle's color, install body kits, replace the engine, etc., and then apply for modification registration with the vehicle management office. According to Article 10, registered motor vehicles must apply for modification registration under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Replacement of the entire vehicle due to quality issues. Change from commercial to non-commercial use or vice versa. The owner's residence moves out of or into the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with designated patterns and equipped with alarms and signal lights as required. Other motor vehicles are prohibited from using patterns, alarms, or signal lights that are specific to or resemble those of the aforementioned vehicles.
