Tips on How to Keep Your Car Cool in Summer


When summer arrives, the scorching heat can turn your car into an oven on wheels. Not only is it uncomfortable for you and your passengers, but extreme heat can also cause damage to various components of your vehicle. However, with some simple tips and tricks, you can keep your car cool and protect it from the sweltering summer temperatures. In this article, we will explore effective strategies and techniques to beat the heat and ensure a pleasant driving experience.

Window Management

One of the easiest ways to keep your car cool in the summer is by managing your windows effectively. Window shades and sun visors are inexpensive accessories that can block out the sun’s rays and reduce the amount of heat entering your car. Additionally, cracking your windows open slightly can create airflow, allowing hot air to escape and cooler air to enter.

Tinting your car windows is another excellent option for reducing heat. Window tint films can block a significant amount of UV rays and heat, keeping the interior of your car cooler. Be sure to check your local regulations to ensure compliance with tinting laws.

Parking Strategies

Finding shaded parking spots can make a significant difference in keeping your car cool. Seek out trees, buildings, or other structures that can provide shade from the sun’s direct rays. If shaded parking is unavailable, consider using carports or parking garages, as they offer protection from the sun and help maintain a cooler interior temperature.

When shade is not readily available, you can create temporary shade with a car cover. Using a reflective cover or fabric can reduce the amount of heat absorbed by your car’s exterior, keeping it cooler for longer periods.

Interior Protection

Protecting your car’s interior is crucial to keep it cool during hot summer days. Seat covers and steering wheel covers can prevent surfaces from heating up excessively and make them more comfortable to touch. Investing in covers made from breathable materials can also help with ventilation.

Placing towels or blankets on hot surfaces like seats and dashboards can provide temporary relief from the heat. Additionally, using reflective windshield covers when parked can minimize the heat buildup inside your car.

Cooling Techniques

Pre-cooling your car before entering is a simple yet effective strategy. Start the engine, turn on the air conditioning, and roll down the windows for a few moments to let the hot air escape before entering. This way, you’ll step into a comparatively cooler interior.

Utilize your car’s air conditioning effectively by setting it to recirculation mode. This helps cool the air inside the car faster by not pulling in hot air from outside. Once the interior temperature is comfortable, switch to fresh air mode occasionally to prevent stuffiness.

Maximizing airflow through vents and fans can also aid in keeping your car cool. Open the vents and use fans to circulate the air, ensuring proper ventilation throughout the cabin.

Maintenance and Precautions

Regular maintenance of your car’s cooling system is essential, especially during the summer months. Have your cooling system inspected and maintained according to the manufacturer’s recommendations. This includes checking coolant levels, inspecting the condition of the radiator, and ensuring all components are in good working order.

Keep an eye on coolant levels and top up as necessary. Inspect the radiator for any signs of leaks or clogs, and clean it if needed. Worn-out weather-stripping can allow hot air to seep into the cabin, so inspect and replace damaged or deteriorated weather-strips promptly.

Insulation and Heat Reduction

Investing in heat-reflective sunshades or windshield films can significantly reduce the amount of heat entering your car’s interior. These products block a considerable portion of the sun’s rays, keeping the cabin cooler. Similarly, applying insulating window films or curtains on side and rear windows can further enhance heat reduction and maintain a cooler environment inside your car.

Another effective method to keep your car cool is by adding insulation to the car’s roof and doors. There are insulation products available specifically designed for automotive use. By installing these insulation materials, you can minimize heat transfer from the outside, keeping the interior temperature lower.

Technology and Accessories

Take advantage of technological advancements and accessories to help keep your car cool in the summer. Solar-powered ventilation fans can be installed on your car’s windows or sunroof to continuously circulate air even when the vehicle is parked. These fans use solar energy to power their operation, providing a constant flow of fresh air and reducing heat buildup.

Remote car starters or mobile apps that allow you to start your car’s engine from a distance can be beneficial in hot weather. By starting your car a few minutes before entering, you can activate the air conditioning system and lower the interior temperature in advance.

Explore aftermarket cooling accessories such as seat coolers or cooling gel cushions. These products provide a cooling effect on the seats, making your driving experience more comfortable, especially on hot summer days.

Emergency Preparedness

While implementing preventive measures, it’s essential to be prepared for unexpected situations. Keep a portable battery-powered fan in your car, which can provide immediate relief in case of a breakdown or when you find yourself in a hot environment without access to air conditioning.

Carry a supply of cold water and wet towels in your vehicle. Wet towels can be placed on seats or used to wipe down surfaces, helping to reduce the temperature inside the car and providing a refreshing sensation.

Lastly, familiarize yourself with the signs of heat-related illnesses, such as heat exhaustion and heatstroke. If you or your passengers start experiencing symptoms like dizziness, nausea, or fatigue, it’s important to take immediate action by seeking shade, applying cold compresses, and contacting medical assistance if necessary.


Keeping your car cool in the summer is crucial for both your comfort and the well-being of your vehicle. By implementing the tips and techniques mentioned above, you can effectively combat the sweltering heat and protect your car from potential damage.
