How to Make Your Car Summer-Ready

As winter ends and temperatures rise, it’s essential to get your car prepared for the demands of summer driving. Properly de-winterising your car and performing key checks can make all the difference in a safe and enjoyable season. Here’s a comprehensive guide on how to get your car summer-ready, covering everything from de-winterisation to keeping your car cool in summer.

De-Winterise Your Car

De-winterising your car ensures it’s ready for warm weather and addresses any effects of winter conditions.

• Remove Winter Accessories: Start by removing winter tyres and replacing them with summer or all-season tyres. This switch is vital, as winter tyres wear down faster on hot roads and impact fuel efficiency.
• Check the Undercarriage: Salt and grit from winter roads can cling to the undercarriage, causing erosion and rust. A thorough wash is essential to protect your car from long-term damage.
• Inspect Fluids: Check for any leaks that might have developed over the winter. Refill or replace fluids, including engine oil and brake fluid, to ensure smooth operation.

Essential Checks Before Summer Driving

After de-winterising, conduct these essential checks to get your car ready for summer conditions.

• Tyre Pressure and Tread: As temperatures increase, tyre pressure can rise by up to 2 PSI for every 10°C. Check and adjust the tyre pressure as needed to prevent blowouts, and inspect the tread to ensure proper grip.
• Coolant System and Radiator: Keeping your engine cool is crucial in summer. Check that the radiator and coolant are working effectively; a coolant mix of 50% antifreeze and 50% water is ideal. This balance helps manage the engine’s temperature in extreme heat.

• Belts and Hoses: High temperatures can wear out the rubber on belts and hoses, potentially causing breakdowns. Inspect and replace any worn-out parts, as these components are crucial for keeping the engine cool.
• Brake Check: Test your brakes for wear or damage, as they are vital for safe summer driving. Hot weather can lead to brake fluid evaporation, reducing braking efficiency.

Keep Your Car Cool in Summer

Keeping your car cool in summer not only enhances comfort but also prevents potential heat-related damage.

• Park in the Shade or Use a Sunshade: Avoid parking in direct sunlight whenever possible, or use a windshield sunshade to block UV rays. This simple step keeps the car’s interior cooler and helps protect the dashboard and seats.
• Inspect Air Conditioning: The last thing you want in summer is a malfunctioning AC. Ensure the refrigerant level is sufficient and address any leaks or issues that may have developed over winter. This step is essential for keeping the cabin comfortable on hot days.
• Tinted Windows: If allowed, tinted windows can be a great way to keep your car cool in summer. Tints block a portion of sunlight, reducing heat buildup inside the car.

Battery, Oil, and Wiper Maintenance

Regular maintenance of your car’s battery, oil, and wipers can prevent overheating and ensure smooth operation during the summer.

• Battery: Heat speeds up chemical reactions in car batteries, which can lead to overcharging and reduce battery life. Check the battery connections, clean any corrosion, and ensure the battery is charging efficiently.
• Oil and Filter Change: High temperatures cause engine oil to thin, which can reduce its effectiveness in lubricating engine parts. Replace the oil and filter according to your car’s recommended schedule, typically every 3,000 to 7,000 miles, to keep the engine running smoothly.
• Wipers: Summer thunderstorms and increased dust mean wipers need to be in top shape. Replace old or cracked wipers to ensure clear visibility, especially at night.

Final Checks and Essentials for Summer Travel

For added safety and convenience, consider these final checks before setting off on a summer road trip.

• Pack Emergency Essentials: Prepare for the unexpected by carrying a summer-specific emergency kit that includes bottled water, a portable battery charger, sunscreen, and a first-aid kit.
• Check Headlights and Taillights: With summer travels often including early starts or late returns, ensure all lights are functional. This step is crucial for safe driving during evening hours.
• Fluid Levels: Besides oil, check other fluid levels such as windshield washer fluid, brake fluid, and transmission fluid. These should be topped up to ensure optimal performance during summer driving.

By following these steps, your car will be fully prepared for the summer season. From de-winterising to essential maintenance checks, taking the time to get your car summer-ready helps ensure a safer and more enjoyable driving experience.
