The car cooling fan, also known as the car radiator, consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. The coolant flows inside the radiator core, while air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, and the cold air heats up by absorbing the heat from the coolant. The reasons for the car's cooling fan to keep running are as follows: 1. The water temperature in the radiator drops slowly. When the engine is just turned off, the water temperature hasn't dropped yet, so the cooling fan will continue to operate for a while before stopping. 2. If the car has completely cooled down but the fan still keeps running, there might be a fault in the cooling fan assembly or its wiring. It is recommended to have it repaired promptly.

What is the role of the no-deductible insurance?

The role of the no-deductible insurance is to transfer the 20% liability loss to the insurance company, which allows the policyholder to obtain maximum protection in traffic accidents and supplements many current commercial insurances. Below is the relevant introduction: 1. Compensation: In traffic accidents, China's auto insurance has clear liability divisions. The insurance company does not provide full compensation, and the policyholder is also required to pay a certain percentage of the amount. Generally, the insurance company only compensates 80%, and the remaining 20% is borne by the policyholder. Its purpose is to restrain the policyholder and minimize the occurrence of claims. The role of the no-deductible insurance is to transfer this 20% liability loss to the insurance company, allowing the policyholder to obtain maximum protection in traffic accidents. 2. Supplementary role: The no-deductible insurance supplements many current commercial insurances, such as vehicle damage insurance and theft insurance. As for whether to purchase the no-deductible insurance, car owners can decide based on their own circumstances. Alternatively, they can choose suitable auto insurance according to their needs to provide better life protection.

Where is the reverse light switch located?

The reverse light switch is installed on the transmission. More relevant information is as follows: Service life: Automotive reverse lights can be divided into gas automotive reverse lights and LED automotive reverse lights based on the materials used. Gas automotive reverse lights use halogen materials. Halogen-based automotive reverse lights feature mature technology and low cost, making them widely used in many vehicle models, with a service life of approximately 8,000 hours. Higher price: LED automotive reverse lights use LED materials. LED-based automotive reverse lights are characterized by being pollution-free, radiation-free, and having a long service life, with a theoretical lifespan of over 50,000 hours. Many vehicle models have now been modified to use LED reverse lights. However, due to their higher price, LED automotive reverse lights significantly impact ordinary users. Especially in China, the adoption rate is quite low, whereas in developed countries, it is relatively high.
