When the warm months roll in, it is important to make sure your car is ready to handle the heat. Higher temperatures and longer trips can take a toll on your vehicle if you are not prepared.
Keeping your car in top shape during summer helps avoid unexpected breakdowns and ensures a safe, comfortable drive. Learn how you can get your car summer-ready and enjoy the season without worries.
Check and Top Up Fluids
Fluids are vital to keeping your car running smoothly, especially in hot weather. Start by checking the engine oil. If it looks dirty or low, change it or top it up. Summer heat can cause oil to break down faster, reducing its effectiveness.
Inspect the coolant level in the radiator. Coolant prevents your engine from overheating, so ensure it is at the recommended level and the mixture is correct. Also, check the brake fluid, transmission fluid, and windscreen washer fluid. Keeping all fluids clean and topped up helps your car handle the extra strain of summer driving.
Inspect Your Tyres
Your tyres take a beating during hot months. Heat causes tyre pressure to rise, which can lead to blowouts if not monitored. Check the pressure when the tyres are cool and adjust according to the manufacturer’s recommendations.

Inspect the tread depth and look for signs of uneven wear or cracking. Tyres with low tread are dangerous, particularly in sudden summer rain showers. If the tread is worn out or the tyres are more than six years old, it might be time to replace them.

Test the Air Conditioning System
Driving without working air conditioning on a hot day is uncomfortable and risky. Before summer is in full swing, test your air conditioning to make sure it is blowing cold air. If it feels weak or warm, the system may need a recharge.
You might also want a professional to check for any leaks or blockages. Regular servicing ensures your air conditioning works efficiently throughout the season, keeping you cool and safe.
Inspect the Battery
High temperatures can shorten your battery’s life. Heat causes battery fluid to evaporate and can damage internal parts. Check the battery for any corrosion on the terminals, loose connections, or bulging.
If your battery is more than three years old, consider having it tested. Most garages can do a quick battery health check to avoid being stranded later.

Replace Worn Wiper Blades
Summer might bring sunshine, but it can also bring sudden showers. Worn wiper blades will not clear your windscreen properly, making it hard to see during a downpour.
Look for any cracks or signs that the rubber is peeling. Replacing your wiper blades is a simple, low-cost job that can make a big difference in visibility and safety.
Check the Brakes
Brakes are critical all year round, but you rely on them even more during summer road trips. Listen for any unusual noises like squealing or grinding. These could indicate worn brake pads or other issues.
Have a professional inspect your brakes if you notice any problems. Maintaining your braking system helps prevent accidents and ensures a smooth driving experience.
Clean and Protect the Exterior
Summer sun can damage your car’s paint and finish. Washing and waxing your car protects the exterior from UV rays, dust, bird droppings, and tree sap. A good coat of wax acts as a barrier, keeping your car looking fresh and new.
Consider parking in the shade whenever possible or using a car cover. Protecting your car from direct sunlight can slow paint fading and interior damage.

Examine Belts and Hoses
Heat can cause rubber belts and hoses to crack, soften, or snap. Inspect them for any signs of wear, fraying, or leaks. Belts should be tight and free from cracks, while hoses should not feel spongy or brittle.
Replacing worn belts and hoses before they fail can save you from costly breakdowns during your summer travels.
Refresh Your Emergency Kit
An emergency kit is essential no matter the season. In summer, it is even more important to have supplies in case you are stranded in the heat. Check your kit to make sure you have:
- Water bottles
- Non-perishable snacks
- Torch and extra batteries
- First-aid supplies
- Mobile phone charger
- Reflective warning triangles
- Basic tools and jump leads
Add sunblock and a hat to protect yourself if you have to wait outside your car.
Keep an Eye on Fuel Economy
Hot weather and heavy air conditioning use can affect your fuel economy. If you notice a sudden drop, it could be a sign of issues like low tyre pressure, dirty air filters, or engine trouble.
Maintaining your car properly keeps it running efficiently, helping you save money on fuel.

Ensure Lights Are Working
Long summer days might mean less night driving, but it is still important to have all your lights working properly. Check the headlights, brake lights, indicators, and reverse lights.
Replace any bulbs that are out and clean the light covers to ensure maximum visibility.
Protect the Interior
Summer sun can make your car’s interior unbearably hot. Use sunshades on your windscreen and windows to reduce heat build-up. Seat covers and dashboard protectors can prevent fading, cracking, and general wear.
Keeping your interior protected not only makes your car more comfortable but also helps retain its value.
Watch for Overheating
One of the most common summer breakdowns is engine overheating. Keep an eye on your temperature gauge while driving. If it starts creeping towards the red, pull over safely and turn off the engine.
Never open the radiator cap while the engine is hot. Allow it to cool before checking coolant levels. Carrying extra coolant in your boot is a smart precaution.
Use the Right Engine Oil
Some manufacturers recommend using a slightly heavier oil in summer to withstand higher temperatures. Check your owner’s manual or ask a professional if a different oil is advisable for summer driving.
Using the right oil ensures better protection for your engine during hot weather.

Enjoy a Season of Summer Drives
Preparing your car for summer is not just about comfort; it is about safety and reliability, too. By checking fluids, tyres, brakes, air conditioning, and more, you can enjoy peace of mind on all your journeys.
Take the time now to prepare your vehicle properly, and you will be rewarded with a smooth, enjoyable driving season.
