Before you load up the car and hit I-65 or I-64 this summer, take 30 minutes to make sure your vehicle is ready. Here's what we check for every customer planning a long drive.
Cooling System — The #1 Roadside Breakdown Cause
Overheating is the most common cause of summer roadside breakdowns. Your cooling system works harder in summer heat and highway driving.
- Check coolant level and condition — flush if it's been 2+ years
- Inspect radiator hoses for swelling, cracking, or soft spots
- Test the radiator cap for proper pressure holding
- Verify the cooling fan operates correctly
- European vehicles: check for plastic coolant component deterioration
💡 Carry a gallon of coolant (the correct type for your vehicle) and a gallon of water in your trunk. If you overheat, let the engine cool completely before opening the radiator cap.
Tires — Your Connection to the Road
Hot pavement and high speeds stress tires significantly.
- Check tread depth — minimum 4/32" for highway driving (more than the legal 2/32" minimum)
- Inspect for cracks, bulges, or uneven wear
- Set pressure to the door jamb spec (not the tire sidewall max)
- Check your spare tire — is it inflated and serviceable?
- Tire age matters: replace tires older than 6 years regardless of tread
Brakes — Stop When You Need To
Mountain driving, heavy traffic, and loaded vehicles all put extra demands on brakes.
- Inspect pad thickness — minimum 3mm for a long trip
- Check brake fluid level and color
- Test for pulsation or pulling during braking
- Verify brake lights work properly
AC System — Comfort and Safety
A working AC isn't just about comfort — it affects driver alertness and safety. If your AC isn't blowing cold, get it checked before your trip. Common causes include low refrigerant, a failing compressor, or a clogged cabin filter.
- Test AC output temperature (should be 35-45°F at the vent)
- Replace cabin air filter for maximum airflow and air quality
- Listen for unusual compressor noises
- Check for refrigerant leaks
Fluids, Belts & Battery
A comprehensive fluid check and belt inspection prevents most mechanical surprises on the road.
- Engine oil — fresh oil before a long trip is cheap insurance
- Transmission fluid — check level and condition
- Power steering fluid, brake fluid, windshield washer fluid
- Serpentine belt — inspect for cracks, glazing, or fraying
- Battery — test voltage and terminal connections
Pack an Emergency Kit
Even a well-maintained vehicle can have issues. Be prepared:
- Jumper cables or a portable jump starter
- Basic tool kit (pliers, screwdrivers, adjustable wrench)
- Flashlight with fresh batteries
- First aid kit
- Phone charger and roadside assistance contact info
- Coolant, oil, and water — one quart each
