Summer is here, and that means longer days, open highways, and plenty of miles ahead. Whether you're planning a weekend escape or a cross-country adventure, summer road trip maintenance in 2026 starts well before you hit the road. A little preparation goes a long way toward keeping your GMC running smoothly all season long. more Why Pre-Trip Maintenance Matters for Your GMC Skipping a pre-trip checkup can turn a great summer adventure into an unexpected roadside stop. Heat puts extra stress on nearly every major system in your vehicle, from the engine and cooling system to the tires and brakes. Before you load up the family and head out from Sparta, Illinois, it makes sense to give your GMC a thorough once-over. Catching small issues early keeps your trip on track and helps protect your long-term investment. Check Your Tires Before You Hit the Road Tires are one of the most important things to inspect before any long drive. High summer temperatures can cause tire pressure to fluctuate, and under-inflated or worn tires increase the risk of a blowout on the highway. Check the tread depth and look for any signs of uneven wear, cracking, or bulging along the sidewalls. Rotate your tires if you're approaching the recommended mileage interval, and make sure your spare is properly inflated. Summer road trip maintenance in 2026 really does begin from the ground up. Inspect Your Cooling System and Fluids Your engine works harder in the heat, which makes the cooling system especially critical during summer driving. Check your coolant level and look for any signs of leaks around hoses and connections. While you're at it, top off your windshield washer fluid and verify that your oil level is correct. Driving with low or old engine oil in summer heat accelerates wear on internal components. If you're overdue for an oil change, now is the right time to schedule one. Test Your Battery and Electrical System Extreme heat is actually harder on car batteries than cold weather. If your battery is three years old or more, have it tested before a long trip. A weak battery may still start your vehicle at home but fail when you're far from help. Make sure battery terminals are clean and connections are secure. Also confirm that all your lights are working properly, including brake lights and turn signals. Don't Overlook Your Brakes and Air Conditioning Summer road trips often mean stop-and-go traffic, mountain descents, or towing a camper, all of which put real demands on your brakes. Listen for any grinding, squealing, or pulsation when stopping. Have your brake pads and rotors inspected if you're unsure of their condition. And don't forget your air conditioning a system that blows warm air on a 95-degree day makes for a miserable ride. Have the refrigerant level and compressor function checked by a professional before departure.
