June 20, 2022 Published by Leave your thoughts

How can heat affect your car? This seems to be a common issue of concern for most car owners. But such individuals don’t have sufficient information on the most appropriate strategies that can help to protect their cars. Hot weather in summer and other seasons has the potential to damage your car. But, what does the heat do to your car?

1. Battery Challenges

Although cold weather is mainly blamed for killing car batteries, the truth is that heat can also cause considerable damage. Under extremely high temperatures, the battery fluid tends to evaporate quickly. Consequently, the level of electrolytes inside the battery gets reduced significantly. The chemical reaction in the battery is also affected, which can lead to a gradual reduction in the battery’s capacity. 

2. Damages to the Cooling System

It’s common knowledge that cars have a cooling system that helps to regulate the temperatures under the hood. The system relies on a 50/50 mixture of water and antifreeze. When it’s extremely hot, the water inside the radiator tends to evaporate quickly. As a result, the coolant level drops significantly, and this can cause the engine to overheat. You need to be aware of the ideal coolant level in your car and ensure that it’s well-maintained to avoid such issues.

3. Effect on Tires

The air pressure inside the tires increases when the temperatures are high. If you don’t maintain the correct tire pressure, the sidewalls might start bulging outwards. In some cases, the heat can also cause the treads to separate from the tires. In most cases, extremely hot weather can force you to replace your tires sooner than expected. It can bring unnecessary repair expenses, which can be pretty costly.

4. Engine Oil

The engine oil of your car is also affected by extreme heat. The oil gets thinner and breaks down quickly when the temperatures are high. This makes it less effective in different lubricating components in the engine. In some cases, it can also cause the engine to overheat. Maintaining the proper oil level and changing it regularly is vital to avoid such issues. Consult with your mechanic to find the ideal oil type and oil change schedule for your car.

5. Air Conditioning

A vehicle’s air conditioning should always be in good working condition, but it’s even more critical during hot weather. When driving in extremely hot temperatures, the air conditioning helps regulate the car’s temperature and makes it more bearable. It also helps to reduce the risk of dehydration, which can be quite dangerous. Unfortunately, hot weather affects your car’s air conditioning system, and it has to work harder to cool the interior. This can put a lot of strain on the system, leading to costly repairs in the long run.


As you can see, hot weather can hurt your car in many ways. It’s important to be aware of these issues and take the necessary steps to protect your car. Regular maintenance is essential to avoid costly repairs down the road. Keep an eye on your car’s different components and ensure they are in good working condition.
