Quick Answer: The summer heat can cause a range of issues for your car, from overheating engines to deflated tires. Proper maintenance and regular checks can prevent these problems and keep your car running smoothly during the hot months.
Sweltering summer days call for road trips to the beach and scenic destinations. While hot summers are great fun, they can also do a number on your car. High temperatures can affect various components of your vehicle, leading to potential breakdowns and costly repairs. Here's a look at some of the key issues you're likely to run into during the peak of summer and things you can do to make sure your car stays in top condition all season long.
Engine Overheating
Your car relies on fluids to keep it running and keep it cool. Coolant protects the cooling system, including the radiator. Over time, coolant loses its efficacy. During the hotter months, this can lead to overheating and the erosion of pipes.
Make sure you change the coolant, especially before the warmer months roll around. You'll also want to check that the coolant remains topped off throughout summer.
Oil changes are important too. During the summer months, oil thins out, which can lead to corrosion on certain engine parts. When the oil runs too thin and the temperatures increase, it can lead to engine failure. Prevent these problems by keeping up with oil changes, as fresh oil is thicker and coats parts better.
Tire Deflation and Blowouts
While hot summer temps are unlikely to melt your tires, the heat can lead to deflation. When tires are no longer at the right pressure, the combination of high internal heat and the heat from the road can lead to blowouts.
Check your tire pressure regularly to remain at safe levels. And if you notice any signs of wear, like low tread or cracks, replace your tires right away.
Battery Corrosion
Summer heat and corrosion can wreak havoc on your car battery. High temperatures can accelerate the chemical reactions inside the battery, leading to quicker deterioration and potential failure. Ignoring this could leave you stranded and sweating on the side of the road.
To make sure this doesn't happen to you, get under the hood and check for corrosion, especially around the connections. Have the battery serviced, and if necessary, replace or recharge it to ensure it remains reliable throughout the summer.
Paint Damage
The beating sun can damage your paint job. First, tiny fissures and cracks start. Then, before you know it, small chunks of paint flake off.
Looking for a shady spot to park is a great start, and keeping the outside of your car clean helps too. Regularly remove debris, such as mud and leaves. Also, consider using a car cover to protect the paint from prolonged sun exposure.
Cracked Pipes, Belts, and Hoses
Plastic and rubber don't do well in the summer sun, and if the weather gets really hot, this can lead to cracks and tears. Regularly inspect these parts and keep up with routine vehicle maintenance to ensure all belts, hoses, and pipes are in good condition. To prevent breakdowns, replace any damaged parts right away.
Air Conditioner Strain
Your air conditioner is an essential component of a good summer road trip, and when it's no longer cooling the cabin, you may be tempted to simply crank the temp down lower. The problem is, doing so can put your car under additional strain. This could lead to a power drain on the engine, causing it to overheat.
Prevent problems by making sure your air conditioner is functioning properly before the summer. If it’s not cooling the cabin effectively, have a technician repair it.
Staying Safe During Those Warmer Months
A great summer is all about pool parties and long vacations. Before you head out, take some time to inspect and maintain your vehicle. This is the best way to make sure your plans don’t get derailed by preventable problems with your car.
