Car radiator fan not working reasons: Water temperature issue: Most car radiator fans nowadays operate with electronic temperature control, so the fan usually starts running normally only when the car's internal water temperature reaches the required level. If the temperature is too low, the radiator fan won't turn. Therefore, if the car radiator fan is not working, check whether the water temperature meets the requirement. Relay malfunction: If the water temperature is appropriate but the car radiator fan still doesn't work, the issue might be with the fan's relay. If the relay malfunctions, the car's radiator fan won't operate. Thermostat switch problem: If neither of the above issues is present, inspect the thermostat switch. Sometimes, the thermostat switch can develop faults, which can also affect the operation of the car radiator fan.

Is it better to replace two tires or all four?

It is better to replace all four tires. The maintenance methods for tires are: 1. Regularly clean the stones in the tire treads; 2. Reduce exposure to sunlight; 3. Frequently check the tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect the front wheel alignment; 6. Be mindful of driving habits. The functions of tires are: 1. Support the entire weight of the vehicle and bear the load of the car; 2. Transmit traction and braking torque to ensure the adhesion between the wheels and the road surface; 3. Reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to car components; 4. Adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring safety, handling stability, comfort, and energy efficiency.

Can Mineral Water Be Stored in the Trunk During Summer?

Mineral water can be stored in the trunk during summer as long as it is not exposed to prolonged direct sunlight, which prevents the trunk temperature from rising excessively. Here is some extended information regarding trunk usage: 1. Essential Items: Reflective warning triangle, used to alert vehicles behind in case of a breakdown. Fire extinguisher, for unexpected vehicle fires. Dust brush, primarily for cleaning glass surfaces. Small emergency light, for signaling help or self-rescue; tools like wrenches and jacks, used for changing tires after a flat. 2. Precautions: Avoid overloading the trunk during daily short-distance trips; do not treat the trunk as a "storage room"; refrain from leaving or forgetting food items in the trunk. It is advisable to use trunk mats made of synthetic fibers, cotton, or wool instead of heavy floor mats, as a set of floor mats can weigh between 10 to 15 kilograms, potentially affecting fuel consumption. Do not store flammable or explosive items such as lighters or hairspray in the trunk, as the enclosed space combined with high temperatures and road bumps could lead to explosions.
