During the scorching summer, it is crucial to stay hydrated and cool to combat fatigue and heat strokes. Commuters often face the challenge of cars heating up quickly under extreme summer temperatures, leading to engine problems and reduced vehicle longevity.

There have been instances of cars catching fire due to excessive heat, emphasizing the need to protect your car’s well-being. Here are essential maintenance tips to keep your car cool during the summer heat.

Cars catching fire can be attributed to various factors, not solely extreme heat. Electrical wiring faults are a significant cause, leading to short circuits and sudden ignition.

Fuel leaks or issues with the fuel tank can result in the spillage of highly flammable gasoline, which can ignite upon contact with a heat source.

Malfunctions in the exhaust system should also be addressed, as they can cause temperatures within the car to rise significantly, posing a fire risk.

Exposure to high temperatures

Apart from faulty parts or malfunctions, prolonged exposure to high temperatures can cause the car’s engine or exhaust system to overheat. 

While moderate summer heat might not be problematic, excessive temperatures can lead to issues. Therefore, it is advisable to park your car in a shaded area when not in use and refrain from smoking inside the vehicle. Also, ensure no flammable materials are left inside the car to minimize the risk of fire.

Common car problems in extreme heat include overheating, tire blowouts, internal electrical system issues, and battery failure. 

AC problems are particularly prevalent during the summer, as the system is overexerted and prone to damage. Regularly check the engine for signs of overheating and exertion, and prioritize AC and internal electric wiring maintenance to keep your car in good condition.

Overheating 

Overheating can cause the air inside the car’s tires to expand, leading to blowouts or leaks. Regularly checking the tire pressure is crucial during summer. 

If unsure, look for signs of tears or overinflation and consult an expert or mechanic. The recommended tire pressure for passenger cars is typically between 30 to 35 PSI.

Fuel evaporation 

In regions with high humidity or during high temperatures, fuel evaporation becomes a concern. While fuel does not evaporate as quickly as water, it is still prone to evaporation. 

So monitor your fuel consumption during summer and aim to keep the tank at least half full to reduce the risk of evaporation. Regularly check your coolant fluid levels using the indicator lines on the coolant reservoir unit to prevent overheating.

Air filters 

Air filters are vital in keeping your car clean from external dust and debris while protecting the engine from harmful particles. During warmer weather, air filters accumulate more dust, necessitating regular cleaning. The air filter is usually located on top of the engine, typically covered, and should be removed for cleaning.

What to do in an emergency? 

In an overheating car while on the road, it is essential to perform emergency cooling. First, pull over to a nearby shaded area and turn off the engine. Allow the car to cool for at least 10 minutes, then open the hood to release any trapped air. 

Once you believe the car has cooled down, turn on the ignition without starting the engine. Monitor the temperature gauge; if it shows a normal range, you can start the engine. However, if abnormal noises persist or the temperature remains high, keep the engine off and seek professional assistance.

It is worth noting that other researchers have also provided insights into cooling cars during the summer. Parking in the shade can help reduce a car’s internal temperature by up to 20° Fahrenheit compared to parking in direct sunlight.
