Essential Car Maintenance Tips for a Road Trip-Ready Summer

There’s nothing like a summer road trip–windows down, music up, and the open road ahead. But before you pack your bags, it’s important to make sure your vehicle is as ready for the journey as you are. A little preventative car maintenance can save you from unexpected hiccups and help you make the most of every mile. 

Whether you’re heading to the lake, the mountains, or across the country, these car care tips will keep your ride smooth and safe. Just follow these tips from Thompson Sales to enjoy all your summer adventures. 

Why Summer Car Maintenance Matters

Getting your car ready for summer isn’t just about comfort. It’s about safety and reliability. A little prep work now can reduce the risk of unexpected breakdowns when you’re miles from home. With the right maintenance, you’ll enjoy a smooth ride now and for many summers to come. 

Check 1: Test Your Tire Pressure and Tread Before Travel

Properly inflated tires with good tread are crucial for safe summer driving. Hot pavement can increase the risk of blowouts. The last thing anyone wants on an adventure is to spend hours on the side of the road waiting for a tow truck.

How to Prepare Your Tires for Travel

• Check tire pressure. Use a gauge to ensure all four tires (and your spare!) are inflated to the recommended PSI. You can find this in the owner’s manual or on the driver’s side door jamb.
• Inspect the tread depth. Insert a penny into the tread with Lincoln’s head upside down. If you can see the top of his head, it’s time for new tires. 
• Look for damage. Scan for cracks, bulges, or objects lodged in the tread that could cause trouble on the road. 
• Be sure you know how to change a tire! This life skill can save time, money, and hassle. If you didn’t learn as a child, read our guide on how to change a tire properly and safely. 

Check 2: Monitor Your Car’s Fluid Levels

Fluids keep your car’s systems running smoothly and help prevent overheating, especially during long summer drives.

What to Check

• Oil: Make sure it’s clean and at the right level. If it’s dark or gritty, schedule an oil change.
• Coolant: Check the reservoir and top off if needed. Coolant helps prevent your engine from overheating.
• Brake Fluid: Low or dirty brake fluid can affect stopping power.
• Transmission Fluid: Essential for smooth shifting and overall performance.
• Power Steering Fluid: Keeps steering easy and responsive.
• Washer Fluid: Don’t forget this one—clear visibility is key for safe driving.

Check 3: Brake Check! Make Sure You Can Stop While on the Go

Reliable brakes are non-negotiable for safe travels, especially if you’ll be driving through hills or heavy traffic.

What to Look For

• Listen for weird sounds. Squeaking, grinding, or squealing noises can signal worn brake pads.
• Feel for changes. If your brakes feel soft, spongy, or require more pressure than usual, get them checked.
• Do a visual inspection. If you can see the pads through the wheel spokes, make sure there’s at least a quarter-inch of pad left.

Check 4: Don’t Let a Bad Battery or Alternator Dim the Summer Fun

Summer heat can shorten a battery’s life. A common cause of roadside trouble, it’s also easy to avoid when you follow the right steps. 

What to Look For

• Check battery terminals. Make sure they’re clean and free of corrosion.
• Test the battery. If it’s more than three years old, have it tested to ensure it holds a charge.
• Inspect the alternator. If you’ve noticed dimming lights or slow starts, ask your mechanic to check the alternator’s output.

Check 5: Make an Emergency Kit Part of Your Car Maintenance Strategy

Even with the best preparation, surprises can happen. A well-stocked emergency kit ensures you’re ready for anything.

What to Pack

• First-aid kit
• Flashlight and extra batteries
• Jumper cables
• Bottled water and non-perishable snacks
• Basic tools (screwdriver, pliers, wrench)
• Tire inflator and sealant
• Phone charger and power bank
• Blanket and sun protection
• Printed map in case of poor cell service

Bonus Tips for Staying Cool and Entertained on the Road

• Air conditioning. Have your A/C system checked and replace the cabin air filter if needed.
• Sun protection. Pack sunglasses, hats, and sunscreen for everyone.
• Entertainment. Download playlists, audiobooks, or podcasts before you go to keep the whole crew happy.
• Snacks and drinks. Keep a cooler handy for cold drinks and healthy snacks to avoid unnecessary stops.
