Does Leaving a Car Outside in the Rain Have Any Impact?

Leaving a car outside in the rain does have an impact. Here are the detailed explanations: 1. Specific impacts: The car's paint surface can be corroded. In many parts of the country, pollution is widespread, and some areas suffer from severe pollution, making the rain essentially acid rain. Therefore, exposing the car to rain is like leaving the paint bare to acid rain, which can corrode the paint, leading to water marks, oxidation, and even cracking. 2. Precautions: Rainwater often contains acidic substances that can corrode the outer glossy layer of the paint. Additionally, rainwater carries microscopic dust particles that, when exposed to sunlight, can generate a large amount of oxides. Hence, it is advisable to perform a paint treatment on your car after rain. A simple and effective method is waxing.

Do Brake Discs Need to Be Replaced Frequently?

Brake discs generally need to be replaced when the vehicle has traveled 80,000 to 100,000 kilometers. Here are the criteria for determining when to replace brake discs: 1. Observe the brake disc warning light: Normally, the brake disc indicator light is off. When there is a fault or excessive wear in the brake disc, the light turns on and goes off after repair. When the warning light is on, the brake disc has worn to its limit, braking performance has decreased, significantly affecting driving safety. Therefore, car owners should regularly check the wear condition of the brake discs to see if they are still usable, rather than relying solely on the warning light. 2. Check the thickness of the brake disc: Most brake disc products have wear indicators, which are three small pits distributed on the disc surface. Using a vernier caliper, the depth of these small pits is measured to be 1.5mm. This means that when the total wear depth on both sides of the brake disc reaches 3mm, the car owner should promptly replace the brake disc.

How High is the Surface Temperature of a Car in Summer?

In summer, the surface temperature of light-colored cars is approximately 40-50 degrees Celsius, while dark-colored cars can reach 70-80 degrees. Below are specific details about car temperatures: 1. Car Temperature: When a car is parked outdoors in 40°C high temperatures and exposed to the sun for a long time, the interior temperature can exceed 70 degrees, reaching up to 90 degrees. In summer, outdoor temperatures in most regions can reach around 40°C. However, most car interiors are black, which absorbs heat more easily. Combined with the enclosed environment, the temperature inside the car can rise sharply over time, creating a sauna-like effect. 2. Car Usage Precautions: Avoid placing flammable or explosive items inside the car; if the car is parked outdoors, it is recommended to use a car cover to shield the body or a sunshade to cover the front windshield to avoid direct sunlight; always open the doors to ventilate before entering the car, and you can turn on the air conditioning to cool down before getting in.
