Driving in Extreme Heat: Essential Summer Car Care Tips for UK Drivers

While the UK may not experience extreme temperatures all year round, summer heatwaves are becoming increasingly common. Temperatures above 30°C can place extra strain on your vehicle, increasing the risk of breakdowns if your car isn't properly maintained.

Whether you're planning a family holiday, commuting to work or heading off on a weekend road trip, taking a few minutes to prepare your car for hot weather can help keep you safe on the road.

At Sandicliffe, we know that preventative maintenance is the best way to avoid costly repairs. Here are our top summer car care tips for UK drivers.

1. Check Your Engine Coolant

One of the most common causes of summer breakdowns is engine overheating.

Your vehicle's coolant helps regulate engine temperature throughout the year, not just during winter. Low coolant levels can quickly lead to overheating, particularly in slow-moving traffic or during long motorway journeys.

Before setting off:

• Check the coolant reservoir when the engine is cold.

• Ensure the coolant sits between the minimum and maximum marks.

• Never remove the radiator cap while the engine is hot.

If you're regularly topping up coolant, it's worth booking a vehicle inspection, as this may indicate a leak or fault within the cooling system.

2. Check Tyre Pressure and Condition

Hot weather causes the air inside your tyres to expand, making tyre pressure even more important during summer.

Driving with incorrectly inflated tyres can affect:

• Fuel efficiency

• Braking performance

• Vehicle handling

• Tyre lifespan

Before any long journey, check your tyre pressures against your manufacturer's recommended settings.

While you're there, inspect your tyres for:

• Uneven tread wear

• Cuts or bulges

• Cracks

• Objects embedded in the tread

Healthy tyres are essential for safe summer driving, particularly during sudden heavy rain showers.

3. Watch for Signs of Engine Overheating

Your dashboard temperature gauge provides an early warning if your engine is getting too hot.

If you notice the temperature rising above normal:

• Switch off the air conditioning.

• Reduce engine load where possible.

• Pull over safely if warning lights appear.

Never continue driving with an overheating engine, as doing so could cause severe engine damage and expensive repairs.

4. Make Sure Your Air Conditioning Is Working

A well-functioning air conditioning system is about more than comfort.

Keeping your cabin cool helps reduce driver fatigue and improves concentration during long journeys.

If your air conditioning:

• Isn't blowing cold air

• Produces unpleasant smells

• Takes longer than usual to cool the cabin

it may be time for an air conditioning service or re-gas.

5. Test Your Car Battery

Cold weather isn't the only thing that affects batteries.

High temperatures accelerate battery wear by increasing fluid evaporation and placing additional stress on internal components.

Common signs your battery may need replacing include:

• Slow engine starts

• Electrical faults

• Dashboard battery warning lights

If your battery is more than three years old, a professional battery health check can provide peace of mind before your summer travels.

6. Check Your Vehicle's Essential Fluids

Regular fluid checks are one of the easiest ways to keep your vehicle running efficiently during hot weather.

Check:

• Engine oil

• Brake fluid

• Windscreen washer fluid

• Power steering fluid (if applicable)

Summer driving often means dusty roads, pollen and insect splatter, so keeping your washer bottle topped up is particularly important.

7. Protect Your Car from the Sun

Extended exposure to direct sunlight can cause interior damage and make your vehicle uncomfortably hot.

To help protect your car:

• Park in shaded areas whenever possible.

• Use a reflective windscreen sunshade.

• Remove valuables from direct sunlight.

• Avoid leaving children or pets inside a parked vehicle.

Dashboard trims, steering wheels and leather seats can quickly become extremely hot during a heatwave.

8. Inspect Your Windscreen Wipers

Summer storms can arrive with little warning.

Worn wiper blades reduce visibility during heavy rain and can smear dirt across your windscreen.

Replace your wipers if they:

• Leave streaks

• Skip across the glass

• Make squeaking noises

• Show signs of cracking

Clear visibility is vital whatever the weather.

9. Pack a Summer Emergency Kit

Even the best-maintained vehicles can experience unexpected problems.

A summer emergency kit should include:

• Drinking water

• Mobile phone charger

• Sunglasses

• First aid kit

• Torch

• High-visibility vest

• Breakdown assistance details

If travelling with children, pack extra snacks and water in case of motorway delays.

10. Book a Summer Vehicle Health Check

The easiest way to prepare your car for hot weather is with a professional vehicle inspection.

A summer vehicle health check can identify worn components before they become expensive problems, helping you enjoy stress-free driving throughout the season.

At Sandicliffe, our manufacturer-trained technicians can inspect your:

• Cooling system

• Battery

• Tyres

• Brakes

• Air conditioning

• Engine fluids

• Belts and hoses

Regular servicing not only helps improve reliability but can also extend the life of your vehicle.

Frequently Asked Questions

Can hot weather cause my car to overheat?

Yes. High temperatures increase the demand on your vehicle's cooling system, particularly during long journeys or when sitting in traffic. Regularly checking coolant levels and servicing your vehicle helps prevent overheating.

Does hot weather affect tyre pressure?

Yes. As temperatures rise, the air inside your tyres expands, increasing tyre pressure. Checking your tyre pressures regularly helps improve safety, handling and fuel efficiency.

Should I service my car before a summer road trip?

Absolutely. A vehicle service or summer health check ensures your tyres, brakes, battery, cooling system and essential fluids are all ready for longer journeys, reducing the likelihood of unexpected breakdowns.

Why is my car's air conditioning not blowing cold air?

Your air conditioning system may require a re-gas, filter replacement or inspection for leaks. Regular servicing keeps the system working efficiently throughout the summer.
