DIY Car Maintenance: 10 Tasks Every Car Owner Should Know

Maintaining your vehicle is not only essential for safety but also helps in prolonging its lifespan. Today we’ll explore 10 essential DIY car maintenance tasks every car owner should master. These tasks will help you save money and ensure your car runs smoothly. Whether you’re a novice or an experienced driver, these tips will empower you to take charge of your vehicle’s upkeep.

1. Check Your Engine Oil Regularly

Why it matters: Engine oil is the blood of your car. Without it, your engine will overheat and wear out quickly.

How to do it:

Open the bonnet
Pull out the dipstick, wipe it clean, insert again and pull it out
The oil level should be between the “min” and “max” lines

Tip: Check at least once a month and always before long trips.

2. Inspect Tyre Pressure & Tread

Why it matters: Under-inflated tyres waste fuel and wear out faster. Bald tyres are dangerous, especially in Nigeria’s rainy season.

How to do it:

Use a tyre gauge
Check for signs of uneven wear or cracks

Pro Tip: Rotate your tyres every 8,000–10,000 km.

3. Top Up Windshield Washer Fluid

Why it matters: Clean windshields = better visibility and safety.

How to do it:

Locate the washer reservoir (usually has a windshield symbol)
Fill with clean water mixed with a bit of glass cleaner

4. Test Your Car Battery

Why it matters: A dead battery = a stranded driver. Nigeria’s heat shortens battery life.

How to do it:

Check for corrosion on terminals
Make sure connections are tight
Use a voltmeter or have it tested at a battery shop

5. Replace Windshield Wipers

Why it matters: In a country with sudden heavy rains, faulty wipers = poor visibility.

How to do it:

Wipers are easy to snap off and replace
If they streak or make noise, change them

6. Check & Replace Air Filter

Why it matters: Dirty air filters reduce fuel efficiency and engine performance.

How to do it:

Open the filter housing (usually plastic and rectangular)
Hold the filter up to light — if light can’t pass through, it’s time to replace it

7. Monitor Coolant Levels

Why it matters: Prevents your engine from overheating — essential in Nigeria’s hot weather.

How to do it:

Locate the coolant reservoir
Make sure it’s between the “min” and “max” line
Only check when the engine is cold!

8. Check Brake Fluid

Why it matters: Low or dirty brake fluid can lead to brake failure.

How to do it:

The reservoir is near the back of the engine bay
Fluid should be clear and at proper level

9. Inspect Belts and Hoses

Why it matters: These keep your engine running smoothly — if they crack or snap, you’re stuck.

How to do it:

Look for signs of wear: cracks, frays, bulges
If any seem brittle or soft, get them checked professionally

10. Keep Your Car Clean – Inside & Out

Why it matters: Regular washing prevents rust, while cleaning the interior improves resale value and your own driving comfort.

How to do it:

Wash with car shampoo and soft cloths
Vacuum the interior weekly
Use protectants on dashboard and leather

Why DIY Maintenance Matters in Nigeria

Prevent bigger issues before they start
Feel more in control of your vehicle
Extend the life of your car
