Exposing a car to the sun in summer has significant impacts. The hazards are as follows: 1. It can cause certain damage to the car paint, interior, air inside the car, and tires. 2. It can affect the car's glossiness. 3. It accelerates the aging of tires and the formation of harmful substances inside the car. Detailed information about the hazards of summer sun exposure to cars is as follows: 1. Car Paint The intense summer sun is very harmful to car paint. Prolonged exposure can accelerate the aging and fading of the paint, causing the car to lose its original beautiful luster and shortening the lifespan of the paint. When summer arrives, it is best to apply glaze or wax to the car paint for effective isolation and protection to safeguard your beloved car. 2. Interior Prolonged sun exposure also greatly affects the car's interior. Most interior components are made of plastic, and prolonged exposure can accelerate the aging and deformation of plastic, damaging the lifespan of the interior. Car owners can place some heat-insulating pads inside the car to prevent direct sunlight from hitting the interior. 3. Air Inside the Car The most significant impact of sun exposure on a car is the production of harmful gases. Most materials inside the car are made of plastic or leather, and prolonged exposure can generate harmful substances such as formaldehyde. If you enter the car and turn on the air conditioning directly without opening the windows, these harmful gases will be inhaled into the body, causing harm. If the car has been exposed to the sun for a long time in summer, it is best to open the windows for a while, turn on the air conditioning in external circulation mode to expel the toxic gases, and then close the windows to cool down. 4. Tires The high temperatures in summer also harm the tires. Tires are made of rubber, and prolonged exposure to the sun can accelerate their aging. Over time, this can cause the tires to deform and crack, affecting their lifespan. Additionally, high temperatures and sun exposure can increase tire pressure, raising the risk of tire blowouts. Therefore, checking tire pressure in summer is very necessary.

What is Body Anti-Rust Inspection?

Body anti-rust inspection is a type of vehicle maintenance. If scratches occur during vehicle use, leading to rust on the paint, a body anti-rust inspection can promptly identify areas prone to rust. Below are some precautions for vehicle body anti-rust maintenance: 1. Wash the car frequently: Regular cleaning helps maintain the car's cleanliness and prevents rust or corrosion. When driving on salt- or alkali-laden roads in winter or near coastal areas, ensure the car is washed at least once a month to minimize rust risks. 2. Repair damaged paint promptly: If cracks or other damage are noticed on the car's paint layer, use quick-drying paint for immediate repairs to prevent rust from starting. If rust has reached the metal parts, take the car to a repair shop for repainting. 3. Install mudguards: For long-term driving on salt- or gravel-covered roads, installing mudguards can effectively keep the car clean. Larger mudguards provide better protection.

What is the function of the lead weights on the wheel rims?

The lead weights on the wheel rims serve to adjust the dynamic balance of the vehicle. The vehicle's tires are also crucial components that ensure safe driving. The small lead weights on the tires, also known as balancing weights, primarily function to maintain the dynamic balance of the vehicle. Most of these lead weights on the tires are internally attached, which allows them to serve their purpose without affecting the vehicle's aesthetics. Although the vehicle's tires and rims are generally circular, due to driving habits, the mass distribution on the tires can be highly uneven. During use, this can lead to imbalances, causing phenomena such as wheel wobbling or steering wheel vibrations. To eliminate such phenomena, it is necessary to add balancing weights—small lead weights—to correct the imbalance of the tires, which is known as dynamic balancing.

What are the reasons for car air conditioning not cooling?

Reasons for car air conditioning not cooling: 1. Condenser issues: After long periods of driving, the condenser accumulates dust, reducing heat dissipation efficiency, which naturally affects cooling. Solution: Clean the condenser; 2. Compressor capacitor damage or malfunction: The AC button controls the compressor. If the compressor isn't working, the air conditioning won't cool. Solution: Repair or replace the compressor; 3. Air conditioning refrigerant leakage: If both internal and external units are working, and the compressor is functioning, it may be due to refrigerant leakage. Solution: Add refrigerant; 4. Loose car air conditioning belt. Solution: Adjust the belt tension.
