How Heat Affects Your Car and How to Protect It

Protect your car from overheating

Summer in Boulder can be hot, hot, hot! And while most Boulderites enjoy the sunshine, our cars don’t always fare as well. High temperatures can take a toll on various parts of your vehicle, leading to potential issues if not properly managed. Let’s take a look at how heat affects your car and what you can do to protect it.

Battery Drain
Heat can actually cause your car battery to lose its charge more quickly. Hot weather speeds up the chemical reactions inside the battery, which can lead to overcharging and shorten its lifespan. If your battery is already a few years old, it might struggle in the heat. Regularly check the battery terminals for corrosion and consider having your battery tested before the heat really cranks up.

Tire Pressure Fluctuations
As temperatures rise, the air inside your tires expands, leading to increased tire pressure. Overinflated tires can cause uneven wear, reduce traction, and even increase the risk of a blowout. On the other hand, as the weather cools in the evenings or during a cold front, the pressure can drop, leading to underinflation. Make it a habit to check your tire pressure regularly, especially during hot spells, and adjust as necessary to maintain the manufacturer’s recommended PSI.

Overheating Engine
An overheating engine is one of the most common heat-related problems. High temperatures put extra stress on your car’s cooling system, which works hard to keep the engine at a safe operating temperature. If the coolant levels are low or if the radiator isn’t working efficiently, your engine could overheat. To avoid this, check your coolant levels regularly, and have your cooling system inspected for any leaks or worn-out parts.

Damage to Belts and Hoses
The rubber components in your car, like belts and hoses, can become brittle and more prone to cracking under extreme heat. This could lead to leaks or even a breakdown if a belt snaps while you’re on the road. Inspect these parts periodically for any signs of wear and tear. Replacing worn-out belts and hoses before they fail can save you from being stranded in the heat.

Paint and Interior Damage
The sun’s UV rays can cause your car’s paint to fade and the interior to crack or fade, especially if your vehicle is parked outside for extended periods. To protect your car’s exterior, consider waxing it to add a layer of protection against the sun. Inside, use sunshades and, if possible, park in shaded areas to prevent the dashboard and seats from getting damaged.

High heat can be tough on your car, but with a little extra care, you can keep it running smoothly all summer long. Regular maintenance checks, especially during the hotter months, can help you catch potential problems before they turn into costly repairs. If you’re due for a check-up or notice anything unusual, bring your car to John’s Auto Care. We’re here to help you beat the heat!
