🔧 Car Parts You Can Repair Yourself — Save Money, Learn More
For many car owners, fixing small problems yourself isn’t just about saving money — it’s about understanding your vehicle and gaining confidence. While some repairs require professional tools and experience, many parts can safely be repaired or replaced at home with basic equipment and patience.
Here’s a practical guide on which car parts you can repair yourself, what to avoid, and how to stay safe.
1. Air Filters and Cabin Filters
Replacing the engine air filter and cabin filter is one of the easiest DIY jobs. You’ll only need a screwdriver or even just your hands. New filters keep your engine breathing well and improve air quality inside the cabin.
How often: every 10,000–20,000 km (check your manual).
Tip: Take a photo before removing the old one, so you install the new one in the same direction.
2. Wiper Blades
Changing wiper blades takes less than five minutes. They’re usually held in place by a clip or hook. Poor visibility due to streaking or squeaking means it’s time for new ones.
Tip: Replace both blades at the same time for balanced wiping.
3. Engine Oil and Filter
If you have access to a flat driveway or ramps, changing engine oil and the oil filter can be a rewarding DIY job.
Tools: oil filter wrench, drain pan, funnel, gloves.
Caution: Always dispose of used oil at an approved recycling centre.
4. Battery Replacement
Car batteries typically last 3–5 years. If your car cranks slowly or electronics flicker, the battery may be weak. Replacing it is simple:
-
Turn off the engine.
-
Remove the negative terminal first, then positive.
-
Swap in the new battery, connect positive first.
Tip: Keep radio codes handy if your system locks after disconnecting power.
5. Brake Pads (for the Confident DIYer)
If you’re mechanically inclined, replacing brake pads can save hundreds of dollars. You’ll need a jack, jack stands, a lug wrench, and a socket set.
Caution: Never skip safety — always secure the vehicle properly and torque bolts to factory spec. If you’re unsure, seek professional help.
6. Spark Plugs
Replacing spark plugs is relatively simple but requires accuracy. Use a spark plug socket and torque wrench to avoid overtightening.
Benefits: smoother idle, better fuel economy, and easier starts.
7. Headlight & Tail Light Bulbs
Most light bulbs are accessible from behind the headlight housing. Avoid touching the glass of halogen bulbs with bare fingers — oil can shorten lifespan.
Tip: Check local laws about bulb brightness or color.
8. Coolant & Washer Fluid Top-Ups
These are low-risk maintenance tasks. Just ensure you use the correct coolant type (check your car’s cap or manual). Never open the coolant reservoir when the engine is hot!
9. Fuses
If an electrical component suddenly stops working (e.g., radio or window), check the fuse box. Each fuse controls a circuit — a burnt one can be replaced for under $5.
Tip: Always replace with the same amperage rating.
10. Tires and Tire Pressure
Rotating tires or checking tire pressure is essential for even wear and better fuel efficiency.
Tools: tire gauge, portable air compressor, torque wrench for tightening nuts.
🚫 Repairs Best Left to Professionals
While DIY saves money, some tasks are better handled by experts:
- Transmission or clutch repairs
- Timing belt or chain replacement
- Suspension alignment
- Airbag or ABS system service
These systems require specialized tools and experience.
✅ Final Thoughts
Working on your own car is empowering and economical. Start small — like filters or bulbs — and gradually build skill and confidence. Always prioritize safety, follow the service manual, and use quality parts from trusted suppliers like Tasman Parts.
Whether you’re maintaining your daily driver or restoring a classic, every DIY job adds to your automotive know-how — and that’s something money can’t buy.
