Ultimate Summer Car Care Guide: Keep Your Vehicle in Top Shape

When temperatures rise, your vehicle feels it too. Ensuring that the car's air conditioning is functioning properly is crucial during the summer months to prevent overheating and maintain comfort. From engine performance to tire pressure, every part of your car is impacted by heat. That’s why following a solid summer car care guide is essential to avoid unexpected breakdowns and keep your car running smoothly all season long.
At Kunes Service, we’re committed to helping you stay safe and cool on the road with expert summer vehicle maintenance. Here’s your ultimate, all-in-one checklist to prepare your car for the heat, long drives, and everything summer throws your way.

Why Summer Car Care Matters

Hot weather doesn’t just test your patience—it puts serious stress on your vehicle. Checking the car's battery is crucial to prevent unexpected breakdowns during the summer. Without proper car maintenance for hot weather, your car is at greater risk of overheating, battery failure, tire blowouts, and inefficient fuel usage.
Taking the time for seasonal car care tips isn’t just smart—it’s preventative. At Kunes Automotive Seasonal Service, we help you prevent expensive repairs and ensure your summer driving is smooth and stress-free.

Summer Maintenance Checklist for Cars

Use this comprehensive summer driving car checklist to stay on top of essential maintenance:
Check Your Fluids

  • Coolant/Antifreeze: Prevents your engine from overheating.
  • Motor Oil: Use high-quality synthetic oil for better heat resistance.
  • Brake & Transmission Fluids: Vital for smooth performance in high temps.
  • Brake Fluid: Check brake fluid levels for optimal brake performance, especially in heavy summer traffic.
  • Power Steering Fluid: Regularly check and top off power steering fluid to ensure easy and safe steering.
  • Windshield Washer Fluid: Summer-ready formulas help handle bugs and grime.

Inspect Your Battery
According to our guide on preventing car battery failure in the summer, heat speeds up chemical reactions in your battery, which can shorten its life. Look for signs of corrosion or slow engine starts.

✅Examine Your Tires and Tire Pressure

In our blog on hot weather tire tips, we highlight that heat increases tire pressure. Check for:

  • Proper inflation
  • Tread wear
  • Cracks or bulges

✅ Test Your AC System

You don’t want to discover your AC isn’t working when it’s 90°F outside. Maintaining your vehicle's air conditioning system is crucial, including checking the AC's functionality and refrigerant levels. Let Kunes Service inspect, recharge, or repair your system to keep things cool.

✅ Protect Your Paint and Interior

UV rays can damage your dashboard, upholstery, and paint. Read our paint and interior protection guide for tips on window shades, ceramic coatings, and regular cleaning.

✅ Replace Wipers and Lights

Summer storms can come fast. It is crucial to ensure that all vehicle lights, including brake lights, are functioning properly for safety. Make sure your wipers are streak-free and your lights are clean and functional.

Cooling System Maintenance

🌡️ Check Coolant Levels and Hoses

Your car’s cooling system is its first line of defense against the summer heat. Start by checking your coolant levels regularly. Low coolant can lead to overheating, which is a common cause of summer breakdowns. Make sure the coolant is topped off to the recommended level and consider a coolant flush if it’s been a while since your last one.
Inspect the hoses connected to your cooling system for any signs of wear, cracks, or leaks. These hoses are crucial for circulating coolant throughout the engine, and any damage can lead to significant issues. If you notice any problems, it’s best to replace the hoses immediately. At Kunes Service, we offer comprehensive cooling system inspections to ensure everything is in top shape, preventing overheating and keeping your engine running smoothly.

Motor Oil and Filter Maintenance

🛢️ Change Oil and Oil Filter for Optimal Performance

Summer heat can be tough on your engine, making it essential to use the right motor oil. High-quality synthetic oil is designed to withstand higher temperatures, providing better protection and performance. Regularly changing your oil and oil filter is crucial for maintaining engine health, especially during the hot summer months.
Old or dirty oil can’t lubricate the engine parts effectively, leading to increased friction and potential damage. By keeping up with oil changes, you ensure that your engine runs smoothly and efficiently, improving fuel efficiency and extending the life of your vehicle. At Kunes Service, we recommend scheduling an oil change as part of your summer car maintenance checklist to keep your engine in peak condition.
