What to Do When the Car Gets Too Hot in Summer?

Solutions for an overheated car in summer: 1. Use car covers or sunshades: Owners can cover the car with an insulating cloth or a sunshade, and place a sunshade on the windshield; 2. Apply window films or ceramic coating: If possible, consider ceramic coating, paint protection film, or applying reflective and heat-insulating films on the windows, which can effectively protect the car from high temperatures and UV damage; 3. Park in a garage or shaded area: Park the car in an underground garage or in visible shaded spots, such as under a sunshade or trees, to effectively shield the car from direct sunlight.
When I first started driving, I also hated how hot the car got in summer, especially after being parked in the sun—it felt like stepping into a sauna. I would use a silver sunshade on the windshield before parking to reflect a lot of the heat, and it’s easy to wipe clean if the car gets dirty. Before getting in, don’t rush to close the doors—open all the windows for a few minutes to let the hot air escape. Then, start the AC, beginning with the external circulation to cool down faster without straining the engine. Regular maintenance of the AC system is also important—check if the refrigerant is sufficient and replace the filter if it’s dirty, otherwise the cold air won’t flow well. On highways, if I feel the temperature rising, I intermittently turn off the AC and use natural ventilation, which saves money and is healthier. On extremely hot days, spraying cool water on the interior helps too. Avoid leaving the car in direct sunlight for too long—it ages the car faster and makes people uncomfortable. I’ve adopted these habits, and it’s made driving much more comfortable and safer.
I drive to work every day, and in the summer, the car gets unbearably hot. My solution is to keep some handy tools, like a compact car spray fan by the door. On hot days, I use it to cool down the car for a few minutes before turning on the AC, which makes it much more comfortable. Parking in an underground garage or under a tree is the best option, but if there's no shade, installing a roof sunshade for a few hundred bucks helps with cooling. Before getting in, I use my phone app to remotely open the windows for ventilation, or wipe the seats with a damp towel to lower the temperature a bit. I don’t rely too much on the AC—setting it around 25°C with higher fan speed and opening the sunroof for airflow is efficient and saves fuel. I also keep insulated seat covers in the car to reduce heat absorption. These little tricks make my drives much more comfortable, and I’ve even recommended them to friends to help them stay cool.
