How to Keep Your Car Cool in Summer



The Importance of a Cool Car in Summer

Hot summer days are fantastic for beach trips and barbecues, but they're less than ideal for your car's interior. Ever sat on scalding leather seats or touched a super-hot steering wheel? Not fun. Keeping your car cool in the summer isn't just a matter of comfort; it's also about safety and prolonging the life of your vehicle.

What You'll Learn

In this comprehensive guide, you'll learn various tips and tricks to keep your car cool, from quick fixes to long-term solutions.

Understand the Car's Cooling System

Basic Components

Before diving into solutions, it's crucial to understand your car's cooling system. Comprising a radiator, water pump, thermostat, and coolant, this system plays a significant role in maintaining a tolerable temperature.

How It Affects Temperature

A faulty cooling system can make summer driving unbearable. Regular maintenance can prevent overheating and ensure a cooler drive.

Preventing the Heat Before Driving

Park in the Shade

A no-brainer, right? Parking in the shade can significantly reduce the internal temperature of your car. Always opt for a shaded spot, even if it means walking a bit further.

Use a Windshield Sunshade

Investing in a good-quality sunshade can block direct sunlight, making a noticeable difference.

Window Tinting

Tinting your windows can block UV rays, reducing heat build-up inside the car. However, remember to check your local laws regarding window tinting.

Quick Fixes for Immediate Cooling

Roll Down the Windows

Simple but effective. Rolling down the windows for a few minutes can flush out the hot air, preparing your car for the A/C.

Use the A/C Wisely

It might be tempting to max out the A/C, but doing so can strain the system. Start with lower settings and gradually increase.

Long-Term Solutions

Reflective Car Covers

Consider investing in a reflective car cover. These covers reflect sunlight, keeping your car significantly cooler.

Solar-Powered Car Fans

These fans run on solar power and can circulate air even when the car is off.

Upgrade Your Car's Insulation

Quality insulation can keep the heat out and cool air in. This is a bit of an investment but pays off in the long run.

Maintenance Tips

Regularly Check the A/C

Ensuring that the A/C is running efficiently can make a world of difference.

Inspect Coolant Levels

Low coolant levels can lead to overheating. Check and refill if necessary.

Clean the Vent System

Dust and debris can block the vents, making the A/C less effective. A clean vent system promotes better airflow.

Understanding Heat Ailments


Being in a hot car can lead to serious health issues like heatstroke. Recognise the symptoms and take immediate action.


Dehydration can creep up on you when you're in a hot car. Always keep water handy.

What to Avoid

Don't Leave Pets or Children in the Car

The temperature inside a parked car can rise dramatically within minutes. Never leave pets or children unattended.

Avoid Plastic and Leather Seats

These materials can get extremely hot. If you have them, use seat covers.

Tech Solutions for a Cooler Car

Remote Start Systems

Some modern cars come with remote start systems that allow you to start the A/C before entering.

Mobile Apps for Climate Control

There are apps available that let you control your car's climate from your phone.

DIY Tricks

Tired of sweating it out in your car but don't want to splurge on high-end solutions? Good news! You can roll up your sleeves and dive into some simple DIY projects that can make a big difference. Trust me, you don't need to be a DIY guru; all you need are basic household items and a bit of creativity.

Make Your Own Car Fan

What You'll Need:
  • A small battery-operated fan
  • Cable ties or sturdy string
  • Optional: A small solar panel
  1. Choose a Spot: First, figure out the best place in your car to set up the fan for optimal air circulation. This could be the back of the headrest, the dashboard, or even near the window.
  2. Secure the Fan: Use cable ties or a sturdy string to attach the fan securely to the chosen spot.
  3. Solar Power Option: If you're environmentally conscious (or just forgetful when it comes to batteries), attach a small solar panel to power the fan. Position the solar panel where it can catch sunlight effectively.
  4. Test: Turn the fan on and feel the difference it makes!

And there you go! You've just made a simple yet effective DIY car fan that can help circulate air, making your drive cooler and more comfortable.

DIY Seat Coolers

What You'll Need:
  • Gel ice packs or DIY ice packs made from sponge and zip-lock bags
  • A towel or seat cover
  • Optional: Velcro strips
  1. Prepare Ice Packs: If you're using gel ice packs, put them in the freezer. If you're making DIY ice packs, just soak a sponge in water, place it in a zip-lock bag, and freeze it.
  2. Layer the Seat: Place a towel or seat cover on the seat where you'll be placing the ice packs. This protects your upholstery and adds a layer between you and the cold packs.
  3. Place the Ice Packs: Take the ice packs from the freezer and put them evenly across the seat.
  4. Secure with Velcro: If your ice packs or your towel keep sliding around, use Velcro strips to keep them in place.
  5. Sit and Chill: Literally! Your DIY seat cooler is ready for use.

These seat coolers can provide instant relief from hot upholstery and make your journey more enjoyable. Just remember to remove the ice packs before they melt!

So, if you're looking for ways to beat the heat on a budget, these DIY tricks are easy, effective, and can be whipped up in no time. Why not give them a try?

Convenience Over Cost

Affordability vs. Efficiency

While some solutions may be pricier, they can be more efficient in the long run.
