Here are some methods to protect and cool down a car when it is exposed to the sun: 1. Use sunshades: When parking the car, place sunshades on the front and rear windshields. This not only provides insulation but also protects the dashboard from direct sunlight. This is a recommended practice. However, it's important to note that the cooling effect of sunshades depends on their reflectivity—the higher the reflectivity, the better the effect. 2. Alcohol spray: Using an alcohol spray bottle can also have a certain cooling effect. 3. Window films: Window films are the most basic products for sun protection and cooling. High-quality films do not obstruct the driver's view and can block the sun's heat, preventing over 70% of light (including UV rays) from entering, thereby achieving a cooling effect. 4. Choose the right parking spot: During summer, try to park the car in a shaded and well-ventilated area, with the rear of the car facing the direction of the sunlight. Since the rear window glass is smaller than the front windshield, this can reduce the amount of heat entering the car and prevent the interior temperature from rising quickly.
During scorching drives, I always prioritize using the front windshield sunshade – this affordable little tool costing just a few dollars effectively reflects sunlight and reduces cabin temperature. Paired with side window sun shades, especially for rear seats where family often sits, the cooling effect becomes even more pronounced. When unprepared, I seek shaded parking spots under trees or buildings to avoid direct sunlight. My summer routine involves deploying these shields before leaving the car, ensuring a cooler interior upon return while protecting seats from aging. I've developed the habit of ventilating the cabin for one minute by opening doors before activating AC, allowing heat escape for faster cooling and better fuel efficiency. This consistent sun protection practice also minimizes dashboard cracks and reduces electronic component failures, saving both hassle and money in the long run.
