Preparing Your Car for a Maryland Summer Road Trip
Before you load the trunk and head for the highway, give your vehicle the same attention as your route and reservations. Maryland summer heat, highway speeds and long driving days can expose weak tires, cooling-system problems, aging batteries and overdue maintenance that may not show up during a short daily commute.

Before a long summer drive, inspect the tires, cooling system, battery and charging system, air conditioning, brakes, engine oil and other applicable fluids, belts and hoses, lights, wipers and emergency equipment.
Long highway miles create sustained heat and load. A vehicle that feels normal during a ten-minute commute can behave differently after hours at highway speed with passengers, luggage and the A/C running.
BEST TIMINGDo your road-trip inspection several days before departure. That leaves time to correct a worn tire, weak battery, fluid leak or other problem without disrupting your trip.

ROAD-TRIP READINESS0/10 COMPLETE
01 · TIRES & WHEELS
Long Highway Miles Put Tires Under the Spotlight
NHTSA recommends checking tire pressure when the tires are cold and using the vehicle manufacturer's recommended pressure from the placard or owner's manual—not the maximum pressure printed on the tire sidewall.
PRESSUREUse the Vehicle-Specified PSI
Check all road tires before departure and the spare when applicable. Underinflation increases heat buildup and can contribute to tire failure.
01
Tread Depth
Make sure tread is sufficient and wear is reasonably even.
02
Sidewalls
Look for cuts, bulges, cracking, punctures or impact damage.
03
Uneven Wear
Irregular wear can point to inflation, alignment or suspension concerns.
04
Spare & Tools
Confirm the spare, jack and wheel tools are present and usable when equipped.
The cooling system has to manage engine heat for hours at a time. NHTSA recommends verifying that coolant is at the correct level and specification and checking the system for leaks and service needs.
COOLANTCorrect Level & Specification
LEAKSRadiator, Hoses & Connections
HOSESBulges, Cracks or Deterioration
TEMPDo Not Ignore Overheating
If the temperature gauge moves unusually high or an overheating warning appears, treat it as a problem—not something to “push through” until the next exit.Continuing to drive an overheating vehicle can cause substantial engine damage.
Extreme temperatures can accelerate battery deterioration. Before a long trip, test a questionable battery and inspect the charging system rather than relying on whether the vehicle started normally that morning.
TEST
Battery Condition
A capacity test can identify a marginal battery before departure.
CHECK
Charging Output
Alternator performance matters during long drives with electrical loads.
LOOK
Terminals & Cables
Connections should be secure and free of significant corrosion or damage.
NOTICE
Warning Signs
Slow cranking, dimming lights or a battery warning deserve diagnosis.
Test the A/C Before Everyone Is Already in the Car
NHTSA recommends checking A/C performance before summer travel because the system works harder as temperatures rise. If cooling is weak, inconsistent or disappears at idle, diagnose it before a long drive.
CABIN COMFORT
Consistent Cold Air
Verify the system cools the cabin normally at idle and during driving.
AIRFLOW
Cabin Filter & Vents
Restricted airflow can reduce comfort even when the refrigeration system is functioning.
HEAT SAFETYNever leave a child or pet unattended in a parked vehicle. Interior temperatures can rise dangerously fast even when outside temperatures do not seem extreme.
05 · BRAKES
Address Brake Symptoms Before Highway Travel
Long-distance travel can involve heavy traffic, sudden stops, mountain grades and fully loaded vehicles. Existing brake problems should be evaluated before departure.
Squealing or grindingSteering-wheel vibrationPedal pulsationVehicle pullingSoft or unusual pedal feelBrake or ABS warning light
If your oil change or another manufacturer-scheduled service will come due during the trip, handling it before departure can simplify the journey and give you a chance to identify other maintenance needs.

VEHICLE-SPECIFIC SERVICEMaintenance intervals and fluid specifications vary by make, model, engine and drivetrain. Follow the schedule and specifications for your vehicle.
07 · BELTS, HOSES, WIPERS & LIGHTS
Inspect the Small Items That Can End a Trip Early
NHTSA specifically recommends inspecting belts and hoses for heat-related deterioration before summer travel. Wipers and exterior lighting also deserve attention before a long drive.

A well-maintained car can still encounter a puncture, traffic closure or other unexpected delay. NHTSA recommends carrying basic roadside and emergency supplies.
Georgia Fuel & Treats provides vehicle maintenance and repair at 9336 Georgia Avenue in Silver Spring, Maryland.
If you are preparing for a summer road trip, we can evaluate maintenance and repair needs related to tires, brakes, cooling, battery performance, fluids and other vehicle systems before you leave.
Check the tires, cooling system, battery and charging system, A/C, brakes, oil and applicable fluids, belts, hoses, wipers, exterior lights and emergency supplies. Address overdue maintenance before departure.
Several days to a couple of weeks before departure is useful because it leaves time to diagnose and repair problems without creating last-minute travel pressure.
Yes. Check tire pressure when the tires are cold and use the vehicle manufacturer's recommended pressure shown on the placard or in the owner's manual.
The cooling system must control engine temperature during sustained hot-weather driving. Verify coolant level and specification and address leaks or overheating concerns before travel.
A battery and charging-system test is useful when the battery is aging or the vehicle has shown symptoms such as slow cranking, repeated jump-starts or electrical problems.
Useful items include a charged phone and charger, first-aid supplies, flashlight, jumper cables, tire-pressure gauge, warning devices, drinking water, food, necessary medications and basic roadside tools.
If cooling is weak, intermittent or abnormal, have the A/C system evaluated before hot-weather travel. Summer heat places greater demand on the system.
