How to Prep Your Car for the Ultimate Summer Road Trip

Few things say “summer” like a road trip—windows down, sun shining, music up, and miles of adventure ahead. Whether you’re planning to explore the countryside, visit family across state lines, or discover new places, making sure your car is road-trip ready should be the first thing on your checklist. A little preparation now can prevent a lot of problems later.

At Kunes Auto Group, we want every mile of your journey to be smooth, safe, and stress-free. Here’s how to get your car prepped and primed for the ultimate summer road trip.

Think of fluids as your vehicle’s lifeblood. Without the right levels and clean fluid conditions, your car’s systems can’t operate properly. Begin with your engine oil—check the level and look at its condition. If it’s dark and gritty, it’s time for a change. Long drives in hot weather can strain your engine, so fresh oil is key.

Next, take a look at your coolant. It plays a vital role in preventing overheating, which is a common issue during summer road trips. Make sure the coolant is at the right level and appears clean. If it looks rusty or murky, a flush may be in order.

Transmission and brake fluids are also critical. While these don’t need to be changed often, low or dirty fluid can cause major performance issues—like rough shifting or unresponsive braking. And don’t forget your power steering fluid and windshield washer fluid. These might not seem urgent, but both are essential for comfort and safety.

Tires are the foundation of a safe road trip. Before you hit the highway, inspect the tread depth. If it’s worn thin, your stopping distance and grip could be compromised, especially in wet conditions. An easy way to check is the penny test—if Lincoln’s head is fully visible when inserted into the tread, it’s time for new rubber.

Proper inflation is another must. Use a tire gauge to make sure each tire matches the pressure recommended on the sticker inside your driver’s door. Don’t forget to check your spare—it could be your best friend if trouble strikes. If your steering feels off-center or your ride is unusually bumpy, have the alignment and balance checked to ensure a smoother, more efficient drive.

A functioning air conditioning system is non-negotiable in the summer months. Turn it on and let it run—does it blow cold air quickly and consistently? Weak airflow or lukewarm air could mean the refrigerant needs to be recharged, or there may be a deeper issue that requires servicing.

While you're at it, consider replacing the cabin air filter. A clean filter not only improves airflow but also keeps dust and allergens from entering the car. And since your A/C relies on belts and hoses to circulate refrigerant, give those a once-over for any cracks, leaks, or wear.

Many drivers don’t realize that heat can be just as damaging to a car battery as winter cold. High temperatures can accelerate corrosion and cause battery fluid to evaporate, shortening the lifespan. If your battery is more than three years old or has shown signs of weakness, it’s a good idea to have it tested. Also, check that the terminals are clean and securely connected—corrosion here can disrupt power flow and leave you stranded.

It’s easy to overlook your lights, but visibility is essential—especially if your road trip includes nighttime driving or sudden summer storms. Take a moment to check all your lights: headlights, brake lights, turn signals, and hazard lights. Replace any bulbs that are out or dim.

Wiper blades are another often-neglected item that can make a big difference. If they squeak, smear, or skip across the windshield, they should be replaced. Also, make sure your washer nozzles are spraying correctly and your reservoir is full.

Finally, make room in your trunk for an emergency kit. Include basics like jumper cables, a flashlight, a tire inflator or sealant, simple tools, road flares or reflective triangles, bottled water, and snacks. It’s always better to be overprepared than underprepared.
