Owning a car comes with responsibility, but basic maintenance doesn't have to be intimidating or expensive. Regular DIY maintenance not only saves you
Owning a car comes with responsibility, but basic maintenance doesn’t have to be intimidating or expensive. Regular DIY maintenance not only saves you money but also helps you understand your vehicle better. Here are ten simple tasks that every car owner should know how to handle.
1. Change Your Oil
Nothing extends engine life better than regular oil changes. While professional oil changes are convenient, doing it yourself can save money and ensure it’s done right.
What you’ll need: Oil filter, new oil (check your manual for type and amount), oil filter wrench, drain pan, funnel, and wrench for the drain plug.
How to do it: Warm up your engine, locate the drain plug underneath your car, place the drain pan below it, unscrew the plug, and let the old oil drain completely. Replace the drain plug, then remove the old oil filter and replace it with a new one. Finally, add fresh oil through the fill hole on top of your engine.
2. Replace Your Air Filter
A clean air filter improves fuel efficiency and engine performance. This 10-minute job requires no special tools.
What you’ll need: New air filter.
How to do it: Locate your air filter housing (typically a black plastic box under the hood), open the clips or remove the screws, take out the old filter, clean out any debris in the housing, and insert the new filter. Close everything up, and you’re done.
3. Check and Replace Wiper Blades
Good visibility is crucial for safe driving. Replace your wiper blades when they start streaking, typically every 6-12 months.
What you’ll need: New wiper blades sized for your vehicle.
How to do it: Lift the wiper arm away from the windshield, press the small tab on the underside of the wiper, slide the old blade off, and attach the new one until it clicks into place. Repeat for all wipers.
4. Inspect and Replace Lights
Functioning lights are essential for safety and legal compliance.
What you’ll need: Replacement bulbs specific to your vehicle.
How to do it: Check all exterior lights monthly. For replacement, access may vary by vehicle—some bulbs can be changed from inside the car, while others require removing housing from under the hood. Your owner’s manual will have specific instructions.
5. Monitor Tire Pressure
Proper tire inflation improves fuel economy, handling, and tire life.
What you’ll need: Tire pressure gauge, air compressor (available at gas stations).
How to do it: Check pressure when tires are cold. Remove the valve cap, press the gauge firmly onto the valve stem, and read the pressure. Compare to the recommended PSI (found on a sticker in your driver’s door jamb or owner’s manual) and add or release air as needed.
6. Rotate Your Tires
Regular rotation ensures even wear and extends tire life.
What you’ll need: Jack, jack stands, lug wrench.
How to do it: Loosen (but don’t remove) the lug nuts before jacking up the car. After securing the car on jack stands, remove the wheels and rotate them according to your owner’s manual pattern (typically front-to-rear or cross-pattern). Reinstall and tighten the lug nuts in a star pattern.
7. Replace Cabin Air Filter
This often-forgotten filter keeps the air inside your car clean and your climate control system working efficiently.
What you’ll need: New cabin air filter.
How to do it: Usually located behind the glove box or under the dashboard. Your owner’s manual will provide exact location and removal instructions. Simply remove the old filter and insert the new one in the same orientation.
8. Check Your Battery
Battery maintenance can prevent unexpected failures.
What you’ll need: Wire brush, baking soda, water, petroleum jelly.
How to do it: First, check for corrosion on the terminals (white or greenish deposits). If present, disconnect the negative cable first, then positive. Mix baking soda and water, clean the terminals with a wire brush, rinse with water, and dry thoroughly. Apply a thin layer of petroleum jelly to the terminals before reconnecting cables (positive first, then negative).
9. Flush Your Cooling System
Your engine’s cooling system prevents overheating and should be flushed every 2-5 years.
What you’ll need: Coolant, distilled water, funnel, drain pan.
How to do it: With the engine cool, carefully remove the radiator cap. Locate the radiator drain plug, place your drain pan underneath, and open the plug. Once drained, close the plug, add a 50/50 mix of coolant and distilled water, and bleed the system of air according to your owner’s manual.
10. Change Your Spark Plugs
New spark plugs can improve engine performance and fuel economy.
What you’ll need: New spark plugs, spark plug socket, ratchet, gap tool.
How to do it: Locate your spark plugs (connected to thick rubber wires or coil packs). Remove one plug wire or coil at a time, use the socket to remove the old plug, gap the new plug according to specifications, thread it in by hand first, then tighten with the socket. Repeat for each cylinder.
