11 Cool Tips for a Comfortable Summer Drive

Michael Kelly

The hotter months can make your summer drive downright uncomfortable. If you leave your car parked in the sun on an 85°F day, you might return to find that the interior cabin air temperature has climbed to 130°F after only an hour. Not only can it be dangerous for you to be in your car when the cabin is that hot, but it can damage electronic devices left in your car and cause your engine to overheat. Here’s how you can beat the heat when parked or driving in the hotter months.

1. Park in the Shade

Park Your Car in the Shade

Parking in the shade of a tree or a building can help keep your vehicle cooler, so take advantage of those shaded areas. If no shade is available, park your car so that the front end is facing away from the sun. This will let in less sunlight, as your back window is smaller than your front window, keeping the cabin temperature down and the front seats from becoming too hot.

2. Crack Your Windows

Leaving your windows cracked is easy enough to do and goes a long way to help keep your cabin cool for your summer drive. In fact, leaving the front windows open two inches can lower cabin air temperature by almost 10°F on a hot day. Note that even with the windows all the way open, you should never leave a person or an animal in the car.

3. Cover the Seats

Hot seats can be extremely uncomfortable and take a long time to cool down, even with the AC running. Keep a few towels in your car and lay them over the seats and the steering wheel before you leave your car in the sun all day.

4. Spin the Wheel

You can keep your steering wheel from becoming too hot without a cover or a towel. Once you’re parked, turn your steering wheel 180° so that the section you keep your hands on isn’t baking in the sun all day.

5. Use a Car Shade

Use a Car Shade to Keep Car Cool

Car shades can help keep your dashboard and seats from becoming incredibly hot. One report found that car shades were able to reduce dashboard surface temperatures by more 43°F.

6. Keep Valuables Out of the Sun

Temperatures of 95°F or more can damage your laptop or smartphone. Leaving your device in the sun can cause the battery to wear out much faster. It can even cause the hard drive to physically expand. If you must keep your device in your car, be sure to place it in the shade—for example, in the trunk or on the floor of the back passenger seat. Keeping your valuables out of sight can also help prevent them from being stolen.

7. Slam the Doors

It may sound juvenile, but slamming your car doors can help force out hot air. While your vehicle is still parked:

  1. Turn on the air conditioning.
  2. Open the lower vent and close the upper vent.
  3. Roll the windows up and open all four doors (or two, if you drive a coupe).
  4. Go to the passenger side and slam the front and rear door shut.

Doing this can help force the hot air out of the cabin. Note that this procedure won’t work for minivans.

8. Use the Lower AC Vent

You can push hot air out of your car more easily by:

  1. Opening your windows
  2. Turning on your AC
  3. Opening the vent closest to your feet
  4. Closing the vent closest to your face.

As the lower AC vent blows cold air, it forces the hot air to rise and flow out the open windows. This is even more effective when you open your sunroof (if you have one, that is).

9. Use the Recirculate Setting

Car Air Conditioning Tip Use Recirculate Setting

Once you push the hot air out of the cabin of the car, roll your windows up and keep the AC running. Continue to bring in fresh air until the cabin reaches a comfortable temperature. Once it has, switch from the fresh air setting to the recirculate setting to recirculate the cool air inside the cabin. This is an especially important step if you find yourself stuck in traffic, as using the fresh air setting can increase your exposure to carbon monoxide emissions. Following these steps can help reduce your exposure to pollutants by up to 76%.

10. Prevent/Handle an Overheated Engine

Prevent: Check, or have a mechanic check, that your vehicle has the proper amount of antifreeze and coolant. Both of these fluids will help maintain engine temperature, whether it is summer or winter.

Handle: If the temperature gauge on your dashboard shows that your engine is becoming too hot, pull to the side of the road. Roll your windows down and turn on the heat and the fan. Doing this will pull the heat from the engine into the cabin. With the windows down, that hot air should flow from the cabin quickly. Do this for about 20 minutes, keeping an eye on your temperature gauge. Once the temperature returns to normal, you can start driving again. If, after 20 minutes, the engine’s temperature has not gone down, call for roadside help.

11. Check the Tire Pressure

Underinflated tires will flatten against the ground more than properly inflated tires. This can increase the amount of friction and heat that the tires are exposed to. Coupled with scorching hot roads, your tires are far more likely to blow out. Make sure that your tires are inflated to the appropriate PSI. You can find the recommended PSI for your vehicle’s tires in the owner’s manual. It’s also listed on the tire PSI sticker located on the driver’s side door jamb.

      Thanks for the great tip cooling your car before putting on the air now that the weather has gone up to 94.

      Since this time of the year for two months on either side of the summer solstice (June 21), the sun’s rays are hottest on cars not parked in the shade from 10:00 AM to 3:00 PM. Therefore, try to do your travelling errands and shopping before 10:00 AM or after 3:00 PM. The sun sits almost directly overhead during the the solstice times mentioned above. And it is the angle of the sun’s rays that effect car interior temperatures when the sun is most intense at these times.

      Cars can become dangerously hot in Florida during the months of May, June, July, August, and September. If your car sits at longer red lights during this season, keep it stocked with water and coolant antfreezes. Watch the gauge for engine temps and always carry an umbrella in the car for sudden summer showers and in case you have to walk in the sun due to breakdown.
