1Cooling System
Summer heat plus highway driving plus mountain passes can overstress your cooling system. Check coolant level and condition. Ensure the radiator fan works.
2Tires
Check all tires including the spare for proper inflation and tread depth. Hot pavement increases tire stress—underinflated tires can blow out.
3Air Conditioning
Test your AC before the trip. A long drive with a broken AC is miserable and can be dangerous in extreme heat.
4Belts and Hoses
Inspect for cracks, bulges, or soft spots. These components fail more often in summer heat. Replace anything questionable before the trip.
5Fluids Check
Top off or change oil, check transmission fluid, brake fluid, and power steering. Bring extra water and coolant for emergencies.
