The reasons for the radiator always overheating are: 1. The cooling fan is malfunctioning. When the car is running at high speed, the heat generated cannot be transferred to the coolant in time, which affects heat dissipation, leading to an increase in coolant temperature and causing issues like boiling over; 2. The car water pump is malfunctioning, with issues such as seized bearings or damaged impellers. Common impeller damages include cracks or loosening from the pump shaft, which slows down the coolant circulation speed and causes the engine temperature to rise excessively; 3. The radiator has many pores formed by cooling fins, which are prone to being clogged by lint, sludge, etc., resulting in poor ventilation and reduced cooling efficiency. This can easily lead to high water temperature in summer, and timely cleaning of the radiator can solve the problem.

What are the new regulations for the annual inspection of three-wheeled motorcycles?

The new regulations for the annual inspection of three-wheeled motorcycles include aspects related to the inspection period and vehicle exemption from inspection. Inspection period: Within 4 years from the date of registration, inspect once every 2 years; after exceeding 4 years, inspect once every year. According to the Road Traffic Law, motorcycles are classified as motor vehicles, and motor vehicles must undergo safety technical inspections within the specified period from the date of registration. Six-year exemption from inspection: This only exempts the vehicle from the inspection line, but the inspection cycle remains unchanged. That is, for the first four years, you need to go to the vehicle management office every two years to collect the inspection label (the vehicle does not need to go). After three exemptions from the inspection line, you need to go once every year thereafter (the vehicle must go). Note that the 6-year exemption is not an exemption from the annual inspection, so every two years during the 6-year period, you must go to the vehicle management office to apply for the inspection compliance label.

Can motorcycles be refueled?

Motorcycles can be refueled, and they can also be refueled at gas stations. Precautions for refueling motorcycles: A driver's license, ID card, vehicle registration certificate, and license plate are required for refueling; refueling is not done directly from the fuel dispenser but at a fixed location set up by the gas station, known as the "motorcycle refueling point," where fuel is dispensed using a dedicated container. Reasons why direct refueling with a fuel nozzle is not allowed: When refueling a motorcycle directly with a fuel nozzle, it is easy to cause gasoline splashing. Additionally, motorcycle engines are usually exposed, especially after long rides, the equipment under the fuel tank becomes very hot. Since gasoline has a relatively low ignition point, direct refueling can lead to spillage, and gasoline dripping onto the hot engine can easily cause a fire.
