As the UK braces for another heatwave, with temperatures forecast to reach 34C, drivers are being urged to take extra precautions to avoid vehicle-related issues. The hot weather significantly increases the risk of tyre blowouts, overheating engines, and other mechanical failures.
Expert Warns of Summer Strain on Vehicles
James Harding, a tyre specialist at Blackcircles.com with over 16 years of industry experience, highlighted the dangers: “As temperatures rise, many drivers are unaware of how much strain summer conditions put on their vehicles. From tyre pressure fluctuations to overheating engines, small oversights can turn into major issues.” He added, “We’re encouraging all motorists to take some precautions before setting off on any summer road trip to make sure their journeys are safe and stress-free.”
Six Essential Checks for Summer Driving
To prepare for the heatwave, motorists should follow these steps:
1. Check Tyre Pressure Regularly
Hot weather can affect tyre pressure, reducing grip, increasing wear, and raising the risk of a blowout if tyres are over- or under-inflated. As temperatures rise, the air inside tyres expands, increasing pressure by around 0.1–0.2 bar for every 10°C. For the most accurate reading, check pressures when tyres are cool, before driving or after the vehicle has been resting in the shade, and inflate to the manufacturer’s recommended levels as listed in the owner’s manual or on the fuel filler cap.
2. Top Up Fluids
Heat puts extra strain on the engine, so regularly check oil and coolant levels. Low fluid levels can lead to overheating and breakdowns. Drivers should also keep screen wash topped up to maintain clear vision amid bugs, dust, and pollen.
3. Protect Against Sun Glare
Sun glare causes thousands of accidents each year. Clean the windscreen inside and out, replace old wiper blades, and keep a pair of sunglasses in the glovebox to improve visibility.
4. Keep an Eye on the Dashboard
Summer conditions can push a car’s system to its limit. If any warning lights appear, especially temperature or engine warnings, pull over safely and investigate or call for help before damage worsens. If a warning light is unfamiliar, search for it or contact a professional mechanic.
5. Inspect Your Air Conditioning System
A functioning A/C is vital not just for comfort but also for demisting windows, which can mist up in the heat when humid air hits a cooler surface. Ensuring complete scope of vision is essential when driving. If the system isn’t cooling effectively, it may need re-gassing.
6. Plan Ahead for Your Trip
With more people heading out on summer trips, roads become more congested, especially around major motorways. To avoid long delays and reduce the risk of stop-start traffic, which can overheat engines and wear out brakes, check routes on traffic apps and plan to drive at off-peak times.
By following these precautions, drivers can help ensure their journeys remain safe and stress-free during the upcoming heatwave.
