Simple DIY Car Maintenance Tips to Save Money & Extend Life

Maintaining your car can often seem like an expensive and time-consuming task.

However, with the right knowledge and tools, you can perform many maintenance tasks yourself, saving money and extending the life of your vehicle.

This guide is designed to help Australian car owners keep their vehicles running smoothly without breaking the bank.


Welcome to the world of DIY car maintenance, a practical way to keep your vehicle in top condition while saving money.

This section introduces the basics of car maintenance, highlighting its importance and how a little DIY effort can lead to substantial savings.

The Importance of Regular Car Maintenance

Regular maintenance is crucial for keeping your car in good condition and ensuring it runs efficiently.

By performing routine checks, you can prevent minor issues from becoming major, costly repairs.

Additionally, a well-maintained car offers better fuel efficiency, which is essential given the fluctuating fuel prices in Australia.

How DIY Maintenance Can Save You Money

DIY car maintenance can significantly reduce the costs associated with vehicle upkeep.

By learning how to perform basic tasks such as oil changes, tyre checks, and fluid top-ups, you can save money on labour costs and markups on parts.

This guide will walk you through the most valuable and achievable DIY maintenance tasks.

Basic Maintenance Checks

Starting with the basics is key to successful DIY car maintenance. These simple yet essential checks and tasks can prevent many common vehicle issues, ensuring your car remains reliable and efficient.

Here, we’ll cover the foundational maintenance every car owner should know.

Maintaining Proper Tyre Pressure and Tread

Correct tyre pressure ensures optimal performance and fuel efficiency.

Check your tyres monthly using a tyre pressure gauge and inflate them to the recommended level, usually found on the driver’s door jamb or in your owner’s manual.

Additionally, check tyre tread wear to ensure your tyres are safe and legal for road use.

Ensuring Fluid Levels Are Adequate

Besides oil, your car relies on several other fluids, including coolant, brake fluid, power steering fluid, and transmission fluid.

Check these levels regularly and top them up as needed to prevent overheating, braking issues, and steering problems.

Inspecting and Replacing Air Filters

A dirty air filter can reduce your car’s efficiency and power. Check your air filter every 12,000 kilometres and replace it if it’s dirty.

This task requires no tools and just a few minutes, making it one of the easiest ways to improve your car’s performance.

Intermediate Maintenance Tasks

Once you’re comfortable with the basics, it’s time to step up to intermediate tasks. These procedures require a bit more skill and can significantly impact your car’s performance and longevity.

Mastering these will not only save you money but also give you a greater sense of achievement.

Replacing Windshield Wipers

Windshield wipers are vital for your safety, especially during Australia’s unpredictable weather. If your wipers leave streaks or miss spots, it’s time to replace them.

This is a simple task that requires no tools and can be done in minutes.

Changing Headlights and Taillights

Good visibility is crucial, and changing a burnt-out bulb is a straightforward task. You’ll typically need a screwdriver to access the bulb.

Always check your car’s manual for the correct bulb type and installation procedure.

Checking and Changing Your Oil

Oil is the lifeblood of your car’s engine, reducing friction and wear on moving parts.

Check your oil level monthly and change it according to your manufacturer’s guidelines, usually every 10,000 to 15,000 kilometres.

You’ll need a wrench, an oil filter, new oil, and an oil collection pan. Remember to dispose of the old oil responsibly.

Replacing Your Car Battery

Car batteries usually last three to five years. Changing a battery requires a wrench and a bit of caution to avoid short circuits.

Always remove the negative cable first and replace it last when installing the new battery.

Advanced DIY Maintenance

As your confidence grows with basic and intermediate tasks, you might be ready to tackle more advanced maintenance.

These tasks require a bit more skill and patience but are well within the reach of a dedicated DIYer. Not only do they save money, but they also provide a deeper understanding of your car’s operation.

Replacing Spark Plugs

Spark plugs are essential for your engine’s performance. Replacing them every 30,000 to 50,000 kilometres can improve efficiency and power.

This task requires a spark plug socket and an extension for your wrench. Follow your vehicle’s manual closely to avoid misfiring.

Changing Your Oil and Oil Filter

This task is more involved than checking your oil and requires draining the old oil, replacing the filter, and filling the engine with new oil.

Always ensure you use the correct type of oil and filter for your car’s engine.

Changing Your Brake Pads

Worn brake pads can compromise your car’s safety. Changing them requires more advanced skills, including using a jack to lift your car and tools to remove the wheels and calliper.

If you’re not confident, this may be a task for a professional.

Flushing the Cooling System

The cooling system should be flushed every two years to prevent overheating and corrosion.

This involves draining the old coolant, flushing the system with water, and refilling it with new coolant. Ensure the engine is cool before starting this task.

Seasonal Maintenance for Australian Conditions

Australia’s unique climate conditions demand specific maintenance routines to keep your car running smoothly throughout the year.

From the scorching summer heat to cooler winter conditions, preparing your vehicle for the changing seasons is key to maintaining its performance and longevity.

Preparing Your Car for Summer

High temperatures can be tough on cars. Check your air conditioning, coolant levels, and tires to ensure they’re summer-ready. Consider a window shade to protect the interior from UV damage.

Winter Maintenance Tips

Colder regions in Australia may not experience snow, but winter can still affect your car. Check your battery, as cold weather can reduce its efficiency.

Ensure your lights are clean and fully functional for darker days. Also, make sure your windscreen wipers are ready to clean your windshield in the rain.

Tools and Equipment Needed for DIY Car Maintenance

Having the right tools and equipment is essential for any DIY car maintenance task. Starting with a basic set and gradually adding more specialized tools can make the process easier and more efficient.

Here’s what you’ll need to begin your journey into DIY car maintenance.

Basic Toolkit Essentials

Start with a basic toolkit including wrenches, screwdrivers, a jack, and a tyre gauge. These tools will allow you to perform most basic maintenance tasks.

Must Have Equipment for Advanced Tasks

For more advanced maintenance, consider investing in a torque wrench, oil filter wrench, and a creeper for under-car access. Safety equipment like gloves and goggles is also essential.

Safety First: Tips for DIY Maintenance

Before diving into any maintenance task, prioritizing your safety and the safety of those around you is crucial.

The right precautions can prevent accidents and ensure that your DIY car maintenance is both effective and safe.

Personal Safety Gear

Always wear protective gear, including gloves and safety glasses, when working on your car. Ensure your work area is well-ventilated, especially when dealing with fluids or chemicals.

Ensuring a Safe Working Environment

Work on a flat, stable surface to ensure your car is securely supported when lifted. Keep children and pets away from the work area, and never work under a car supported only by a jack.


In conclusion, DIY car maintenance offers a rewarding way to understand your vehicle better, save money, and ensure it stays in great condition.

While not every task is for everyone, knowing when to tackle a job yourself and when to seek professional help is part of becoming a savvy car owner.

When to Seek Professional Help

While DIY maintenance can save money and provide satisfaction, some tasks are best left to professionals.

If you’re unsure about a repair, it’s safer and often more cost-effective to seek expert advice.

Summary of Money-Saving Tips

By performing regular maintenance, you can prevent costly repairs and extend the life of your car.

This guide has outlined the most effective DIY tasks to help you save money and keep your car running smoothly.
