When temperatures soar, your car feels it too. Just like pets can suffer from overheating, your vehicle also struggles under extreme heat. A little preparation can go a long way in keeping your car running smoothly and avoiding unexpected breakdowns.
Even if you don’t live in a scorching climate year-round, heat waves can strike when you least expect them. Protecting your car from high temperatures can save you money, stress, and even safety concerns down the road. Here’s how to get your ride summer-ready.
1. Check Your Battery
Heat drains car batteries faster than cold weather does. High temperatures speed up the evaporation of battery fluid, which can lead to corrosion and power loss. Before summer hits, have your battery tested to ensure it’s holding a charge. If it’s more than three years old, consider replacing it to avoid getting stranded.
2. Top Off or Change Your Fluids
Fluids evaporate more quickly in extreme heat, which can lead to engine trouble. Check and top off essential fluids, including engine oil, coolant, transmission fluid, and brake fluid. If it’s been a while since your last oil change, now is the time to get it done with the right viscosity oil for hot weather.
3. Inspect and Maintain Your Cooling System
Your car’s cooling system works overtime in extreme heat. A failing radiator or low coolant levels can cause overheating, leading to costly damage. Check hoses for cracks, leaks, or loose connections, and ensure the coolant is at the proper level. A flush and refill might be necessary if it’s been a while.
4. Test Your Air Conditioning System
A weak air conditioning system isn’t just uncomfortable—it can be dangerous in high temperatures. If your AC isn’t blowing cold air, have it checked for leaks or low refrigerant levels. Recharging the system or replacing a worn-out compressor could be the fix you need to stay cool on the road.
5. Keep an Eye on Tire Pressure
Tires expand in extreme heat, which can lead to blowouts if they’re overinflated. On the flip side, underinflated tires wear out faster and reduce fuel efficiency. Check your tire pressure regularly, especially before long drives, and keep them inflated to the manufacturer’s recommended PSI.
6. Protect Your Interior from Sun Damage
Your car’s interior can get scorching hot, damaging your dashboard, seats, and steering wheel. Use a windshield sunshade, park in the shade when possible, and consider window tinting or UV-protective sprays to reduce heat buildup. For leather seats, applying conditioner can prevent cracking.
7. Carry an Emergency Kit
Hot weather breakdowns can be dangerous. Keep an emergency kit stocked with essentials like water bottles, electrolyte drinks, sunscreen, a flashlight, jumper cables, and a basic first aid kit. If you have pets, add extra water and a collapsible bowl in case they’re traveling with you.
8. Wash and Wax to Protect Your Paint
The sun’s harsh rays can fade and crack your car’s paint over time. A good wash followed by a protective wax layer creates a barrier against UV damage. If possible, park in a garage or use a car cover to keep your paint job looking fresh.

9. Monitor Your Engine Temperature Gauge
While driving in extreme heat, keep an eye on your temperature gauge. If it starts creeping toward the red zone, pull over safely and let the engine cool down before opening the hood. Overheating can lead to severe engine damage, so don’t ignore warning signs.

10. Plan Your Drives Wisely
Try to avoid driving during peak heat hours, usually between noon and 4 p.m. If you must drive, wear lightweight clothing, bring plenty of water, and take breaks if needed. Running errands early in the morning or later in the evening helps you and your car stay cool.
By taking these steps, you’ll keep your car running safely and efficiently in extreme heat. A little preparation now can save you from costly repairs and stressful roadside emergencies later. Stay cool and drive smart!
