6 Essential Car Maintenance Checks Before a Long Road Trip
A lengthy journey can turn minor automotive problems into significant failures. Fortunately, most mechanical issues can be identified in advance. Essential inspections include: 1. Tire tread depth (less than 2/32 inch compromises traction) and pressure (verify against the manufacturer's specifications). 2. Engine oil level and quality (use a dipstick; dark, gritty oil signals the need for a change). 3. Coolant level and quality (inspect the reservoir; refrain from opening the radiator when hot). 4. Battery condition (look for corrosion; have it tested at auto parts stores; consider replacing if it's older than three to five years). 5. Windshield wipers (examine the blades; replenish washer fluid). 6. Brake status (listen for squeaking; check fluid levels). Conducting these checks can help avoid breakdowns during your trip.
Key facts
- Tire tread depth below 2/32 of an inch is illegal in most US states and reduces wet traction.
- Underinflated tires generate more heat at highway speeds, increasing blowout risk.
- Tire pressure should be checked against the manufacturer's specification, not the number on the tire.
- Engine oil should be checked with the dipstick on level ground, following the owner's manual.
- Coolant reservoir should be checked visually; never open the radiator while hot.
- Battery terminals should be inspected for corrosion; most auto parts stores offer free battery testing.
- Car batteries typically last three to five years; proactive replacement is advised before long trips.
- Windshield wipers should be inspected for cracking and replaced if questionable; washer fluid should be topped off.
- Brake grinding indicates worn pads requiring prompt attention; low fluid may indicate leaks or worn pads.
- For mountain driving, professional brake inspection is recommended due to sustained braking demands.
