Car repairs can be expensive, but many maintenance tasks are simple enough for anyone to do at home. Learning these basic DIY car fixes can save you money, improve your vehicle’s longevity, and keep you safe on the road.
Here are the most essential car maintenance tasks every driver should know how to do.
1️⃣ How to Check & Change Your Oil
🔎 Why It’s Important:
✔ Keeps the engine lubricated and running smoothly.
✔ Prevents overheating and reduces engine wear.
🛠 DIY Steps:
✅ Park on level ground and turn off the engine.
✅ Locate the dipstick, pull it out, and wipe it clean.
✅ Reinsert and remove again to check the oil level and color.
✅ If it’s dirty or low, drain the old oil and add new oil (check manual for correct type).
🚨 Change your oil every 3,000–7,500 miles, depending on the oil type!
2️⃣ How to Replace Wiper Blades
🔎 Why It’s Important:
✔ Ensures clear visibility in rain, snow, and dirt.
✔ Prevents streaking and poor windshield contact.
🛠 DIY Steps:
✅ Lift the wiper arm, press the release tab, and remove the old blade.
✅ Attach the new blade, making sure it locks into place.
✅ Test the wipers with washer fluid to ensure smooth movement.
🚨 Replace wiper blades every 6–12 months or when they streak!
3️⃣ How to Check Tire Pressure & Tread Depth
🔎 Why It’s Important:
✔ Proper pressure improves fuel efficiency and handling.
✔ Good tread prevents hydroplaning and improves traction.
🛠 DIY Steps:
✅ Use a tire pressure gauge to check PSI (found in owner’s manual or driver-side door).
✅ Inflate or deflate tires as needed.
✅ Use the penny test—insert a penny into the tread. If you see Lincoln’s head, replace the tire.
🚨 Check tire pressure monthly and before long trips!
4️⃣ How to Jump-Start a Car
🔎 Why It’s Important:
✔ Gets your car running if the battery dies.
✔ Prevents you from getting stranded.
🛠 DIY Steps:
✅ Connect the red (positive) clamp to the dead battery’s positive terminal.
✅ Attach the other red clamp to the working car’s positive terminal.
✅ Connect the black (negative) clamp to the working car’s negative terminal.
✅ Attach the other black clamp to an unpainted metal surface on the dead car.
✅ Start the working car, wait a few minutes, then start the dead car.
🚨 Never connect the black clamp to the dead battery—it can cause sparks!
5️⃣ How to Replace an Air Filter
🔎 Why It’s Important:
✔ Improves engine performance and fuel efficiency.
✔ Prevents dirt and debris from damaging the engine.
🛠 DIY Steps:
✅ Locate the air filter box under the hood.
✅ Open the cover and remove the old, dirty filter.
✅ Insert a new air filter, making sure it fits snugly.
🚨 Replace the air filter every 12,000–15,000 miles!
6️⃣ How to Change a Car Battery
🔎 Why It’s Important:
✔ Keeps your car starting reliably.
✔ Prevents sudden power loss and electrical issues.
🛠 DIY Steps:
✅ Turn off the engine and disconnect the negative (-) cable first, then the positive (+).
✅ Remove the old battery and place the new one in.
✅ Reconnect the positive (+) cable first, then the negative (-).
🚨 Dispose of old batteries properly—auto shops often recycle them!
7️⃣ How to Replace Brake Light & Headlight Bulbs
🔎 Why It’s Important:
✔ Essential for night driving and signaling other drivers.
✔ Prevents tickets and safety hazards.
🛠 DIY Steps:
✅ Remove the cover or housing for the light.

✔ Helps maintain resale value.

🛠 DIY Steps:
