How to Keep Your Car Cool in Summer
The Short Answer: There is a combination of strategic methods and helpful technology to keep your car cool in the summer. This includes parking in shaded areas, using window protection, ventilation, and a remote car starter to pre-cool your vehicle before you enter.
Every summer, countless drivers face the same challenge: returning to a scorching hot car that's been baking in direct sunlight. Within just 60 minutes, a car's interior temperature can climb 20 degrees above the outside temperature, creating dangerous conditions for passengers and damaging electronic devices and interior surfaces.
The good news is that maintaining a cooler car during summer months is achievable through several practical methods. While many drivers focus on basic solutions like cracking windows or using sun shades, they often overlook one of the most effective modern solutions: a remote car starter system. Let's explore the different strategies to beat the summer heat and transform your vehicle from a summer sauna into a comfortable sanctuary.
Understanding Car Heat Buildup
How hot can your car get?
- Even on a 60°F day, your vehicle's interior temperature can reach 110°F in a couple of hours
-
On a hot summer day, surface temperatures on the dash, steering wheel, and seats can reach 160°F, and the air temperature can reach 130°F
Different materials respond differently to heat buildup:
- A dark interior can heat up 30°F within an hour
- Dashboards exposed to direct sunlight can heat up to 180°F
-
Steering wheels can become untouchable or damaged
These extreme temperatures can lead to warping, fading, and premature aging of interior components.
Hot Cars Can Lead to Critical Safety Concerns
The dangers of a hot car extend beyond just discomfort:
- Safety risks to passengers: Children and pets are especially vulnerable to heat-related illness
- Electronic damage: Navigation systems can malfunction when exposed to high temperatures
-
Interior damage: Harmful UV rays can fade and crack dashboards, seats, and other surfaces
Common misconceptions about hot cars:
Contrary to popular belief, cracking your windows only reduces interior temperature by about 2-3 degrees, far from adequate protection against dangerous heat buildup.
Another dangerous misconception is that hot car incidents only happen on extremely hot days, when in reality, even mild spring days with moderate outdoor temperatures can create life-threatening conditions inside a parked vehicle.
Understanding these truths is crucial for implementing effective cooling strategies that actually work.
Hot Car Prevention Strategies
Strategic Parking Choices
Where you park your vehicle can make a dramatic difference in the interior temperature during warm weather.
Best parking options (ranked by effectiveness):
- Covered parking garage or structure
- Shady parking spot beneath large trees
- North-facing spots (receive the least direct sunlight)
- East-facing spots in the afternoon hours
-
West-facing spots in the morning hours
A shady area can reduce your car's interior temperature by up to 25°F compared to parking in direct sunlight. While finding shade isn't always possible, it should be your priority during summer months.
Protective Equipment
Investing in quality protective equipment can help maintain comfortable cabin temperatures.
Heat-resistant accessories make a significant difference in summer comfort. Multi-layer windshield sun shades can lower interior temperature by up to 40°F, while light-colored seat covers protect upholstery and stay cooler than dark materials.
Breathable seat materials, such as mesh or perforated covers, improve comfort on hot days by allowing air circulation. Heat-resistant steering wheel covers prevent painful contact with scalding surfaces, and dashboard covers block harmful UV rays while reducing heat buildup on your vehicle's most exposed interior surface.
These accessories not only keep your car cooler but also protect interior surfaces from sun damage, extending the life of your vehicle's components.
Must-have protective gear:
- Windshield sun shade: blocks 95% of incoming solar heat
- Rear window shade: provides complete protection
- Window tinting: blocks up to 99% of harmful UV rays
- Window visors: allow ventilation while parked
- Dash cover: protects the dashboard from sun damage
- Steering wheel cover: prevents the steering wheel from becoming too hot
When selecting a sun shade, look for double-sided designs with a reflective surface facing outward and a white or silver surface facing inward for maximum effectiveness.
Smart Cooling Solutions
Remote Starters
A remote starter lets you start your vehicle’s engine from a distance using a key fob or smartphone, offering added convenience and comfort, especially in extreme weather. While it doesn’t control your car’s climate settings directly, it can pre-cool or pre-warm your cabin by running the engine and using the last active climate settings. A remote starter is one of the most effective investments for maintaining a cool car during summer heat.
By activating your vehicle's air conditioning system before you enter, you can:
- Pre-cool your car to a comfortable temperature while staying in air-conditioned spaces
- Reduce wear on interior materials caused by extreme heat
- Extend the life of dashboard components, leather seats, and electronic displays
-
Eliminate the discomfort of entering a hot car on a sunny day
MyPushcart remote starters are made for simple, do-it-yourself installation, so you can avoid the high costs of having a shop do it for you. When you order from MPC, you get everything you need to install your remote starter at home and enjoy the comfort, convenience, and savings that come with it.
Temperature Management
Air conditioning best practices:
- Maintain your system: Regularly check coolant levels and replace cabin air filters annually
- Initial cooling: Set the temperature to the lowest setting and use "fresh air" mode for the first few minutes
-
Quick cool-down method:
- Start with open windows for the first minute of driving
- Allow superheated air to escape
-
Then close the windows and switch to AC with recirculation
The common mistake of immediately turning on the AC system with windows up actually traps the hot air inside, making the cooling process longer and less efficient.
Advanced Cooling Tips
For those hot summer days when standard solutions aren't enough, try these advanced cooling techniques:
- Use reflective window covers for all windows: Don't just cover the windshield, cover side and rear windows too
- Cool touch points first: When entering a hot car, immediately cool the steering wheel and seat belt buckles with a small spray bottle of water
- Create airflow during drives: Use the "4/40 technique", open all four windows, and drive at 40 mph for rapid air exchange
-
Park strategically with the sun's movement in mind: Remember that shade moves throughout the day
Protect Your Car and Comfort with Smart Cooling Habits
Keeping your parked car cool during scorching summer months doesn't require expensive solutions, just smart strategies and a few key investments.
Keeping your parked car cool during scorching summer months is achievable with several simple strategies. Find a shady spot or use a parking garage whenever possible, and use quality sun shades for both the windshield and rear window.
For maximum comfort, use a remote starter to pre-cool your car before entering and maintain your cooling system with regular checks of coolant levels. Protect interior surfaces with appropriate covers and shades or consider professional window tinting to block harmful UV rays. These combined approaches significantly reduce your car's interior temperature on even the hottest days.
Remember that a little preparation goes a long way. Taking a few minutes to set up proper sun protection and ventilation can save you from the discomfort of entering an extremely hot car and prevent long-term damage to your vehicle's interior.
