Methods to cool down a car exposed to sunlight in summer: 1. Open the doors for ventilation: After a car is exposed to sunlight in summer, it's best to first open the doors to allow air circulation, which helps the car gradually cool down. Once the interior is less stuffy, close the doors and turn on the air conditioning. It's also advisable to use a heat-insulating pad on the seats to avoid excessive heat. 2. Apply car glaze: To reduce the heat caused by UV rays, car manufacturers have developed a high-molecular UV-reflective paint care agent. Applying a layer of this agent on the car's surface in summer can help prevent the body from overheating and minimize UV damage. 3. Clean the radiator: When washing the car, remember to clean the radiator, as it tends to accumulate various impurities that hinder engine cooling. Cleaning the radiator is one way to help cool down the car. 4. Install a sunshade: Summer sunlight can heat up the car's interior. A sunshade can reflect sunlight and prevent direct exposure. Sunshades are typically placed on the front and rear windows. Using a sunshade can significantly lower the temperature of the seats and dashboard, making it an effective cooling method. 5. Park with windows slightly open: In summer, if a car is parked with all windows closed, the interior can become hotter than the outside temperature. To prevent this, leave a small gap (about the width of a finger) when parking to allow air circulation between the inside and outside, thereby reducing the interior temperature. Be cautious not to leave too large a gap to avoid theft of valuables. 6. Park in the shade: The primary reason a car gets hot is direct sunlight exposure. Whenever possible, park the car in a professional underground garage, under a tree, or in any other shaded area. This is the most effective way to prevent the car from overheating.

I have my own tricks for cooling down the car after it's been exposed to the summer sun. As a frequent driver, I always open the doors and windows to ventilate for three minutes first, letting the hot air escape before starting the engine and turning on the AC. Set the AC to external circulation mode, increase the fan speed, and avoid directing the vents straight at people to prevent catching a cold. Before parking, I make it a habit to place a windshield sunshade to reduce interior heat buildup, while also checking if the tire pressure is too high to avoid driving safety hazards. Additionally, clean the AC filter every quarter to prevent dust from affecting cooling efficiency. If the car has been exposed to the sun for too long, parking in an underground garage or under shade is better—the temperature difference inside and outside the car is smaller, making cooling faster and more effective. I also keep a bottle of cold water in the car for emergencies, as it's easy to get thirsty on hot days.

Years of driving experience have taught me that prevention is key. In the summer, I always park in shaded areas, such as under trees or in underground garages. If that's not possible, I use a full car sunshade cover. Before turning on the air conditioning, I open all the windows to let the hot air out, run the fan on external circulation for a few minutes to dissipate the heat, and then turn on the AC, setting it to a moderate temperature of around 24 degrees to avoid excessive energy consumption. Tires also require attention, as high temperatures can cause pressure to rise. I check the tire pressure monthly to prevent blowouts. For the interior, such as seats and the dashboard, I use sunscreen spray to prolong their lifespan. These small habits save fuel, enhance safety, and help the car last longer.

Cooling down requires skill. I first open all car doors to ventilate for one minute, then enter the car to start the engine and air conditioning. Set the AC to cooling mode with external circulation, temperature around 24°C, and medium fan speed—avoid setting it too low to prevent excessive load. Check if the refrigerant is sufficient and refill it promptly if needed. Installing sunshade window film is quite effective in reducing heat radiation. Smart car owners can use a mobile app to remotely start the fan for pre-cooling, which is convenient and time-saving. Maintain the air conditioning system every six months by cleaning the filters and ducts to ensure efficient operation. Drive more efficiently to save energy and reduce environmental impact.

When traveling with children or the elderly, extra caution is needed for cooling. I always check the seat temperature before getting in the car—if it's too hot, I never sit down immediately. Instead, I roll down the windows for five minutes to let the heat dissipate. Set the air conditioning to a moderate 24°C and adjust the vents away from sensitive individuals. Keep ice packs or a small fan in the car for quick cooling. From a health perspective, high temperatures can easily cause dehydration, so always stock enough drinking water in the vehicle. Choose breathable seat materials to prevent sweating. Park in shaded areas or schedule trips during cooler morning/evening hours to avoid midday sun exposure. Regularly disinfect the AC ducts to prevent bacterial growth and illness—safety always comes first.

Prefer eco-friendly travel with natural cooling methods. I first open the car doors to release heat, use the fan's external circulation for a few minutes before closing windows and setting AC to around 25°C to save fuel. Park in shaded areas or underground garages to reduce AC reliance. Apply sunshade films to lower interior heat and activate seat ventilation for comfort. Smartly use EV's scheduled AC feature to pre-cool before departure. For long-term care, clean the interior monthly to remove dust. Carry a foldable sunshade to prevent burns—simple, practical, and energy-efficient. This way, travel is both comfortable and environmentally friendly—why not?
