UK drivers urged to do 'strange' thing during the heatwave

The UK is set to sizzle once more this weekend, amid the third heatwave of the year. While many relish the balmy weather, it can also bring about a host of problems.

This is particularly true when it comes to your car, van or other vehicle. With the mercury set to rise to over 30C again, car experts at Budget Insurance are offering drivers important tips on what they say are essential maintenance checks they need to perform before hitting the open road.

Here's what you need to check in your car during this weekend's heatwave, including one 'strange' action:

Inspect your battery

Scorching temperatures can be more damaging to your battery than cooler ones, causing internal harm and shortening its lifespan, reports Yorkshire Live. If your vehicle is taking longer than usual to start and the interior lights are dimming as you crank the engine, it might be time for a new battery, especially if it's over three years old.

Keep an eye on your tyres

Tyres tend to expand in hot weather, which can lead to the rubber cracking and heighten the risk of a blowout. Make sure all your tyres are up to UK and EU standards by having a tread depth of at least 1.6mm.

It's also crucial to inflate your tyres to the correct pressure. Underinflated tyres increase drag on the wheels, making the engine work harder and guzzle more fuel, and are another culprit behind blowouts.

Top up your fluids

Your coolant is key to preventing your engine from overheating during the hotter months, so it's essential to check its level more often, particularly before embarking on a lengthy trip. The experts advised: "Strange as it may sound, you should top it up with both water and antifreeze, because a lack of the latter could damage your engine when temperatures begin to drop."

Use your air conditioning wisely

In sweltering conditions, it might be worth leaving your car doors and windows open for a brief period before setting off, rather than immediately switching on your air conditioning. This can help cut costs and boost engine efficiency.

For shorter trips, driving with the windows down instead of using the air con could be more economical. It's also sensible to park in shaded spots to keep your vehicle cool, reducing the initial need for air conditioning.

Plan your route

Do some homework on the locations of service stations and charging points along your journey. EV drivers can use apps like Chargemap, Chargepoint and Octopus Electroverse to plan their routes.

Chris Lawson, head of car insurance at Budget Insurance, emphasised the importance of vehicle maintenance during the summer months: "With tens of millions of leisure journeys made by car over the summer months, motorists should ensure their vehicle is roadworthy before they set off, whether on holiday or for a day trip.

"Cars can struggle at this time of year, contending with hot temperatures and traffic jams, so it's important that drivers do all they can to minimise the risk of breaking down."
