Car parts most vulnerable during heatwaves: One check before your trip can save you from costly repairs

Scorching temperatures pose a significant threat to vehicles, stressing critical components and elevating the likelihood of malfunctions. Drivers should pay close attention to the engine and cooling system, as a clean and well-maintained engine dissipates heat more effectively. Ensuring the thermostat and fan are functioning correctly is vital for timely cooling.

Extreme high temperatures do not only create problems for drivers and passengers but also put additional strain on almost all important car parts.

Before embarking on long journeys, it is advisable to check engine oil and coolant levels. The oil should be near the maximum mark for optimal cooling, and the coolant level should be roughly in the middle of the reservoir. Even maintenance-free batteries can be affected by prolonged sun exposure, so their condition is worth verifying.

A clean and technically sound engine dissipates excess heat more effectively, while a functioning thermostat and fan enable timely cooling.

Extreme heat also impacts tires. Drivers should not lower tire pressure in hot weather; underinflated tires flex more, leading to faster heating and potential damage. Tire pressure should adhere to manufacturer recommendations, with higher settings for fully loaded vehicles. Inspecting tire tread, sidewalls, and inner surfaces for cracks or damage is crucial, as high temperatures accelerate wear and reduce elasticity.

Drivers should not lower tire pressure in hot weather. An underinflated tire bends more, causing it to heat up faster and become more easily damaged.

Concerns about overfilling fuel tanks in extreme heat are often misplaced, as modern systems are designed to handle fuel expansion. However, ensuring the tank's ventilation system is functional is important. Parking in shaded areas significantly helps reduce interior temperatures, making the air conditioning system's job easier and more fuel-efficient. Regular maintenance of the AC system, including cleaning the condenser and replacing cabin filters, further enhances its performance.

It is a common misconception that the fuel tank should not be filled to the brim during extreme heat due to the risk of explosion.
