With temperatures rising across the UK, motorists are being urged to give their vehicles a summer health check to avoid overheating, breakdowns or safety risks during hot weather.
Car experts at LeaseLoco have warned that many drivers hit the road for summer holidays or weekend trips without checking if their vehicle is ready for the heat – increasing the risk of breakdowns, battery failures, or even blowouts.
The expert advice comes as thousands of Brits gear up for summer travel – whether to the coast, countryside or festivals.
Despite common assumptions, more breakdowns happen in summer than winter, with over 25% occurring in July, August and September, compared to 22.8% in the colder months.*
From tyres and coolant to air con and battery health, neglecting summer car maintenance could not only leave drivers stranded, but also lead to expensive repair bills or delays during the peak holiday season.
John Wilmot, CEO and founder of car leasing deals site LeaseLoco.com commented: “There’s a spike in preventable breakdowns every summer – often caused by simple things like under-inflated tyres, old batteries or low coolant levels.
“Hot weather puts extra strain on your car, especially if you’re loading up with passengers and luggage for long drives.
“But taking just a few minutes to check your vehicle can save you time, money and hassle later on.”
Here are eight essential summer checks every driver should do:
- Coolant levels
Low or leaking coolant is one of the biggest causes of breakdowns during hot weather, as engines are far more likely to overheat. Make sure the coolant reservoir is filled to the correct level and check for any cracked hoses, loose connections or visible leaks under the car. If the coolant appears rusty or sludgy, it may need to be replaced.
- Tyre pressure and tread
Rising temperatures cause the air in your tyres to expand, which can lead to over-inflation, while tyres already under pressure are more likely to suffer a dangerous blowout. Always check your tyre pressure when tyres are cold, and ensure tread depth is above the legal minimum of 1.6mm. Don’t forget to check your spare tyre too.
- Air conditioning
If your air con isn’t blowing cold air or takes a long time to cool the cabin, it could need recharging or maintenance. A functioning air conditioning system isn’t just about comfort – it also helps keep you alert and prevents fatigue during long journeys. Many garages offer affordable re-gassing services.
- Battery health
High temperatures can speed up chemical reactions inside your car battery, shortening its lifespan and increasing the risk of failure. This is especially common in older batteries. Check for signs of corrosion on the terminals and, if your battery is over three years old, consider a test or replacement before summer travel.
- Fluid levels
Engine oil, brake fluid, power steering fluid and windscreen washer fluid are all essential for safe and smooth operation in the heat. Low oil can lead to engine damage, while reduced brake fluid may affect stopping distances. Check levels regularly and top up using the correct type for your vehicle.
- Windscreen and lights
Insects, dust and road grime can quickly build up in summer, reducing visibility. Make sure your windscreen is clean inside and out, and replace worn wiper blades if they’re smearing or squeaking. You should also inspect your headlights, brake lights and indicators to ensure they’re clean and working properly.
- Paintwork and interior protection
Prolonged sun exposure can damage your car’s exterior and interior. UV rays can cause paint to fade, crack plastic trim, and warp or bleach dashboard surfaces. You should try to use a reflective windscreen shade, park in the shade when possible, and consider waxing your car to add an extra layer of protection.
- Book a pre-holiday check-up
If you’re heading off on a long drive or summer holiday, it’s wise to book your car in for a professional once-over. A mechanic can spot worn-out components or hidden issues before they cause problems mid-journey – saving you from delays, breakdowns or costly repairs down the line.
