What to Do When the Car Interior Is Too Hot?
4 Answers
Solutions for an excessively hot car interior: 1. Turn on "internal circulation" after 2-3 minutes of cooling: Internal circulation has the advantages of fuel efficiency and rapid cooling. In high summer temperatures, using internal circulation is better for quickly lowering the temperature inside the car. 2. Repeatedly open and close the car door: Increase the car speed slightly to create air convection, which can accelerate the expulsion of hot air. 3. Use a front windshield heat shield: After turning off the vehicle, simply place the reflective shield on the front windshield to reduce the interior temperature by several degrees. 4. Seat ventilation: The seat ventilation function is commonly found in mid-to-high-end models. After the car seats are exposed to the sun in summer, their temperature rises sharply. The seat ventilation function continuously delivers cool air through a unique ventilation system from the small holes in the seat cushion and backrest.
I often go on long-distance road trips, and when the car gets too hot, the first thing I check is whether the air conditioning system is cooling properly. If the AC isn't cold, it could be due to insufficient refrigerant or a dirty, clogged filter. It's best to visit a repair shop before summer to check and refill the refrigerant. Opening the windows for a few minutes to ventilate can quickly dissipate the accumulated heat, making the AC more effective when turned on. Using a sunshade to cover the windshield and windows when parked can reduce the interior temperature by about 20 degrees. During heatwaves, avoid parking directly in the sun; instead, look for shaded spots or indoor garages. Keeping a small fan or spray bottle in the car for emergencies can help prevent heatstroke. Driving safety is crucial, as high temperatures can lead to fatigue and distraction, so regular maintenance of the AC filter is important. Simple actions can greatly improve the driving experience, especially when traveling with children, requiring extra caution.
For daily commuters, the solution to an overheated car is simple. Open all windows for a minute before getting in to let hot air escape, then start the engine and turn on the AC. Use reflective sunshades to cover the front windows when parked—it’s low-cost and highly effective. While driving, crack open a side window or sunroof for ventilation, paired with the AC’s recirculation mode. Avoid parking in direct midday sun; opt for shaded roadside spots. Keep the interior tidy—clutter absorbs heat. Stay hydrated in hot weather with a water bottle. Making this a habit ensures a more comfortable drive, while long-term neglect may lead to costly AC repairs. Safety first: extreme heat can pose health risks, so don’t underestimate it. This strategy suits busy lifestyles for quick relief.
According to experienced drivers, preventing excessive heat inside the car is crucial. Before each summer, maintain the air conditioning system and clean the filters to ensure smooth cooling. Park in shaded areas or use a car cover for sun protection. After starting the vehicle, wait two minutes with windows open to release heat before closing them and turning on the AC for faster cooling. If the AC isn't cold, check for low refrigerant levels and top up if needed. Avoid keeping flammable items in the car to reduce high-temperature risks. These habits save money and hassle, ensuring safe and comfortable driving without panic in hot weather.
