Summer issues to watch for

Sun and high temperatures can cause extra issues for your vehicle. Here’s what to look out for.

As temperatures soar and the sun blazes overhead, summer brings a unique set of challenges for your vehicle. The scorching heat can wreak havoc on various car components, leading to potential issues that may leave you stranded on the roadside. Being aware of what can go wrong with your car in the summer heat is crucial for proactive maintenance and ensuring a smooth and troublefree driving experience.

Overheating

One of the most common issues during summer is engine overheating. The combination of high ambient temperatures and increased demand on the cooling system can push your engine to its limits, and a malfunctioning thermostat, or a failing radiator fan can contribute to overheating. Regularly check coolant levels and ensure the cooling system is in good working order to prevent this potentially severe problem.

Battery problems

Extreme heat can accelerate the chemical reactions inside your car’s battery, leading to a shortened lifespan. Additionally, high temperatures increase the rate of water evaporation from the battery’s electrolyte, potentially causing the battery to fail.

Before summer sets in, have your battery tested, clean any corrosion on the terminals and consider replacing an ageing battery to avoid unexpected breakdowns.

Tyre blowouts

Asphalt temperatures can soar during the summer, causing tyres to heat up. Overinflated or underinflated tyres are more prone to blowouts, especially when exposed to prolonged periods of hot pavement. Check and adjust tyre pressures every time the season changes, inspect for signs of wear, and ensure proper alignment to minimise the risk of tyre blowouts during summer driving.

Air conditioning failures

The air conditioning system is a summer saviour, providing relief from the heat. However, constant use and exposure to high temperatures can lead to A/C system failures. Common issues include refrigerant leaks, a malfunctioning compressor, or a faulty condenser. Regularly service your A/C system, address any issues promptly, and recharge refrigerant as needed to keep it running efficiently.

Fluid evaporation

The summer heat can accelerate the consumption of essential fluids, such as engine oil, transmission fluid, and brake fluid. Low fluid levels can lead to increased friction, overheating, and diminished performance. Regularly check and top off all fluid levels.

Damaged belts and hoses

The heat of summer can accelerate the wear and deterioration of belts and hoses under the hood. Cracked or damaged belts may fail, leading to engine problems, while fatigued hoses can result in coolant leaks. Regularly inspect belts and hoses for signs of wear and replace them as needed to prevent unexpected failures.

Cracked windscreens

Extreme temperature fluctuations, especially if your car is parked in direct sunlight, can lead to stress on the windscreen and contribute to cracks or chips. Repair any minor damage promptly to prevent it from spreading and compromising the integrity of the windshield.

Fading paint and interior damage

The sun’s UV rays can take a toll on your car’s exterior and interior. Fading paint, cracked dashboards, and deteriorating upholstery are common issues. Regularly waxing your car can protect the paint, and using sunshades or parking in the shade can preserve the interior.

As the mercury rises, being proactive about your car’s maintenance becomes essential to avoid these potential issues associated with summer heat. Regular inspections, timely repairs and proper care can go a long way in ensuring that your vehicle remains reliable and performs optimally, allowing you to enjoy your summer travels without unexpected roadblocks.
