Summer in Maryland brings blazing temperatures, and your car feels it even more. According to the National Highway Traffic Safety Administration, the inside of a parked vehicle can heat up fast, rising about 20 degrees in just 10 minutes and 30 to 40 degrees within half an hour. On an 85°F day, that means your car’s interior could reach 120°F or higher as sunlight heats the surfaces inside and traps the heat like a greenhouse, making it dangerously hotter than the air outside.
Here are some steps you can take to protect your vehicle from heat damage and stay comfortable behind the wheel.
Park in the Shade Whenever Possible
According to the American Academy of Pediatrics, heat builds up fast when your car is left in direct sunlight. Whenever possible, park in the shade or under a covered area. If shade isn’t available, try to position your windshield away from the sun. Using a reflective sunshade can also help block UV rays and lower the interior temperature.
Crack the Windows Safely
Leaving your windows slightly open (just a crack) can help prevent heat buildup and allow air to circulate. Just make sure it is safe to do so, especially if you’re in a high-traffic or high-theft area.
Use Remote Start (If Available)
If your car has a remote start feature, it’s a great tool for cooling the interior before you get in, especially on hot days. Just be sure your vehicle is parked in a secure area and not left running unattended for long. According to Kelley Blue Book, remote start can help restore a comfortable cabin temperature in extreme heat.
Service Your A/C System
Maryland summers aren’t the time to find out your air conditioning isn’t working. Get your A/C system checked at the start of the season to make sure it’s blowing cold air and running efficiently.
If your A/C isn’t cooling properly, it might need a refrigerant top-off or a leak check.
Avoid Overloading Your Vehicle
Heavy loads can strain your engine and make your air conditioner work harder, so if you’re heading out on a summer road trip, pack light to avoid overheating or engine trouble.
Watch for Signs of Engine Overheating
Watch for signs of engine trouble, such as steam from under the hood, dashboard warning lights, or a rising temperature gauge. If your engine begins to overheat, pull over safely, turn off the car, and wait until it has completely cooled before opening the radiator cap.
Stay Prepared with Summer Essentials
Keep a small emergency kit in your car with bottled water, phone chargers, a flashlight, and first-aid items. Consider adding a small cooler or sun hat for long trips or roadside stops.
We hope that these tips help you drive smarter and cooler this smarter! A cool, well-maintained car is a safer and more enjoyable ride. Taking a few simple precautions can help prevent heat-related damage, improve fuel efficiency, and keep you comfortable on the road.
