Car Maintenance Checklist
Maintaining Your Car: A Simple Guide to Keeping Your Vehicle in Top Shape
Keeping your car running smoothly doesn’t require you to be a mechanical expert—it just takes a bit of time, attention, and consistency. The key is knowing what maintenance tasks are needed and how often to perform them. By understanding the basics of car care and following a regular maintenance schedule, you can ensure your vehicle remains reliable and efficient.
A well-maintained car not only performs better but also holds its value. When it’s time to sell, documented upkeep can help you command a higher resale price. While maintenance costs are part of vehicle ownership, they can save you from much more expensive repairs down the road.
To help you stay on track, we’ve created a simple, downloadable car maintenance checklist. Below is an overview of important tasks—both short-term and seasonal—to help you care for your car with confidence.
Short-Term Maintenance Tasks
1. Check Oil and Coolant Levels
Inspect oil and coolant monthly, or every few gas fill-ups—especially before long trips. Always check levels when the engine is cool. Low levels of either can lead to serious engine damage. Refer to your owner’s manual for location and specifications.
2. Inspect the Air Filter
The air filter helps keep debris out of your engine and ensures proper airflow. A clean filter can boost fuel efficiency and reduce emissions. This is an easy task you can do at home—consult your owner’s manual for replacement intervals.
3. Monitor Tire Pressure and Tread Depth
Properly inflated tires are essential for safety and fuel efficiency. Use a tire pressure gauge monthly and before long trips. Don’t forget to check the spare. Also, inspect tread depth using the simple “penny test.” Note: Tire pressure can drop by 1 PSI for every 10°F decrease in temperature.
4. Test All Lights
Each month, check that your headlights, turn signals, brake lights, and parking lights are working correctly. Park in front of a flat surface, turn on the lights, and walk around the car. Ask someone to help check your brake lights.
5. Change Oil and Oil Filter
Oil lubricates and protects your engine’s internal components. Change the oil and filter every 3,000 to 10,000 miles, depending on your vehicle and oil type. Always follow your manufacturer’s recommendation.
6. Rotate Tires
Uneven tread wear can reduce tire lifespan and cause vibration or noise. Rotate your tires regularly (every 5,000–7,500 miles) to promote even wear.
7. Wax Your Vehicle
Wax your car every six months to protect the paint from contaminants like dust, salt, and UV rays. Regular waxing helps prevent rust and maintains your car’s finish.
Long-Term Maintenance Items
8. Check Transmission Fluid
Like engine oil, transmission fluid lubricates moving parts. Check and replace it according to your manufacturer’s schedule to avoid costly repairs.
9. Transfer Case Fluid (AWD/4WD)
In AWD and 4WD vehicles, the transfer case distributes power to the axles. Have the fluid checked and replaced as recommended—this typically requires a visit to a professional.
10. Inspect Shocks and Struts
These components absorb road impact and support steering control. Have them checked every 50,000 miles or sooner if you notice poor ride quality or reduced handling.
11. Flush Coolant System
Your radiator keeps the engine from overheating. Flush the coolant system at regular intervals to remove buildup and ensure optimal performance. Follow your owner’s manual for timing.
12. Replace Spark Plugs
Spark plugs ignite the air-fuel mixture in your engine. Worn plugs can reduce engine power and efficiency. Replace them based on your manufacturer’s guidelines or if you notice performance issues.
13. Inspect the Serpentine Belt
This belt powers systems like the alternator, A/C, and power steering. Visually inspect it for cracks or wear and replace it as needed.
14. Service Differentials
Differentials distribute power to the wheels. They require lubrication to function properly. In AWD/4WD vehicles, both front and rear differentials may need fluid replacement—follow manufacturer recommendations.
Seasonal Maintenance Tips
15. Replace Windshield Wipers
Wiper blades should be replaced annually, or as needed. For winter, consider installing special winter wipers and always lift wipers off the windshield when parked to prevent freezing.
16. Test Battery Performance
Your battery powers the starter and all electrical systems. Extreme temperatures can reduce performance, so have it tested regularly—especially before winter.
17. Switch to Winter Tires
In colder climates, winter tires provide better traction and handling below 32°F. Their rubber compounds remain flexible in freezing temperatures, improving safety and control.
18. Check Antifreeze Levels
Antifreeze protects your engine from freezing. A 50/50 mix of coolant and water is typically recommended. Always check levels before winter hits.
Final Thoughts
Staying on top of your car’s maintenance schedule—and keeping records—can significantly extend your vehicle’s lifespan and reduce the risk of unexpected repairs. Whether you’re doing it yourself or relying on a professional, routine maintenance is a small investment that pays off with better performance, safety, and resale value.
