How to Perform a Basic Car Maintenance Check

Regular car maintenance is not only essential for the longevity of your vehicle but also for your safety and that of your passengers.

This comprehensive guide is intended to empower you, especially if you’re in Australia, with the knowledge and skills to perform a basic car maintenance check at home.

Understanding the Importance of Regular Car Maintenance

Regular car maintenance goes beyond keeping your vehicle on the road; it can save you significant costs on repairs and minimise the risk of breakdowns.

By keeping your vehicle in top shape, you also ensure its optimal fuel efficiency and the overall driving experience.

Moreover, regular checks will help you identify potential problems before they become serious issues, ensuring safety on the road.

Getting Started: Essential Tools and Safety Precautions

Before diving into car maintenance, it’s important to have the necessary tools at hand and understand the safety measures required.

This will not only streamline the process but also prevent accidents and damage to your vehicle.

Gathering Your Tools

Your basic toolkit should include items like a jack, lug wrench, tyre pressure gauge, oil filter wrench, funnel, and other essentials.

Also, ensure that you have the right fluids for topping off such as engine oil, transmission fluid, brake fluid, coolant, and windscreen washer fluid.

Having a good pair of gloves and safety goggles can also come in handy.

Understanding and Following Safety Guidelines

Always ensure that you’re working in a well-ventilated area and that your car is turned off before starting. If you’re working under the vehicle, use jack stands to support it.

Always dispose of fluids responsibly; they should not be poured down drains or directly onto the ground.

Most importantly, if a maintenance task seems too complex or dangerous, do not hesitate to contact a professional.

Checking Your Vehicle’s Fluid Levels

Vehicle fluids are the lifeblood of your car; they lubricate, cool, clean, and perform other functions to keep your vehicle running smoothly.

Maintaining the correct fluid levels is crucial for the proper functioning of your car.

Engine Oil

The engine oil is crucial for lubricating the moving parts of the engine, reducing friction, and preventing overheating.

Check this by pulling out the dipstick, wiping it clean, inserting it back, and then pulling it out again to see the oil level. If the level is between the two marks on the dipstick, you’re good to go.

If it’s below, you’ll need to add more oil. Also, note the colour of the oil; if it’s very dark or dirty, it might be time for an oil change.

Transmission Fluid

Transmission fluid ensures the gears in your vehicle shift smoothly and without damage.

Checking this requires running the vehicle until it’s warm and then locating the transmission dipstick, which is usually at the back of the engine.

The fluid should be pink or clear, not brown or black. If the level is low, or the fluid is dark, it should be topped up or replaced respectively.

Brake Fluid

Brake fluid plays a critical role in your braking system. To check this, find the brake fluid reservoir in the engine bay, typically a small translucent container.

The fluid level should be between the “MIN” and “MAX” lines. If it’s low, top it up with the right kind of brake fluid for your vehicle.


The coolant prevents your engine from overheating. You can check this by looking at the coolant reservoir in the engine bay.

There should be markings for minimum and maximum levels, and the fluid should be between these marks. Always check the coolant when the engine is cool to prevent burns.

Windscreen Washer Fluid

While not critical to your vehicle’s operation, having a clear windscreen is essential for safe driving. The reservoir for windscreen washer fluid is typically marked with a windscreen icon or similar.

Fill it up with a washer fluid or water if the fluid is low.

Power Steering Fluid

Power steering fluid ensures your car is easy to steer. This can be checked by locating the power steering reservoir in the engine bay, often labelled or showing a steering wheel icon.

Similar to other fluids, ensure it’s within the marked levels on the reservoir.

Examining Your Vehicle’s Battery

A vehicle’s battery is a vital component, starting the car, powering the lights, and providing energy to other electrical components.

Checking your battery includes examining it for any corrosion, ensuring the connections are tight, and the battery is secure.

If you have a multimeter, you can check the battery’s voltage—it should read around 12.6 volts when the engine is off.

Assessing the Tyres

Good tyre maintenance can improve your car’s handling, fuel economy, and overall safety. This involves checking the tyre pressure, tread depth, rotation, and alignment.

Tyre Pressure

Proper tyre pressure is essential for safe and efficient driving. Use a tyre pressure gauge to check that your tyres’ pressure is within the recommended range found in your vehicle’s manual.

It’s best to check the tyre pressure when they’re cold, as heat from driving can increase the pressure.

Tyre Tread Depth

The tread on your tyres helps to maintain grip on the road, especially in wet conditions. Use a tread depth gauge to check the depth of your tyres’ tread.

In Australia, the legal minimum tread depth is 1.5mm. If it’s any lower than this, it’s time to replace your tyres.

Tyre Rotation

Tyre rotation involves changing the position of each tyre on your vehicle to ensure even wear. Check your vehicle’s manual for recommended tyre rotation patterns and frequencies.

As a general rule, tyres should be rotated every 5,000 to 10,000 kilometres.

Wheel Alignment

Proper wheel alignment ensures optimal drivability and reduces tyre wear. If your car pulls to one side or you notice uneven tyre wear, it’s likely time to have your wheel alignment checked by a professional.

Inspecting the Lights and Electrical Components

Functional lights and electrical components are necessary for safe driving, especially at night and during adverse weather conditions. Regularly checking these components can help prevent accidents.


Your vehicle’s headlights should be checked for brightness and alignment. Turn them on in a dark area and observe the light’s intensity and direction.

If they appear dim or pointed in the wrong direction, they may need to be replaced or adjusted.

Tail Lights

Tail lights are crucial for signalling your presence to vehicles behind you, especially at night. Check these in a similar manner to your headlights. If they’re not illuminating correctly, the bulb might need replacing.

Turn Signals

Turn signals indicate your intentions to other drivers, helping to prevent accidents. Activate your turn signals one at a time, and walk around your vehicle to ensure they are functioning properly.

Interior Lights

Interior lights contribute to the visibility of instruments and controls inside your vehicle. Ensure these are functioning correctly and replace any bulbs that have burnt out.

Dashboard Warning Lights

Dashboard warning lights are your car’s way of telling you something is wrong. Familiarise yourself with what each light means, and if one illuminates, address the issue promptly to prevent further damage.


If an electrical component in your vehicle stops working, it may be due to a blown fuse. Your vehicle’s manual should provide information on where the fuse box is located and how to change a fuse.

Checking the Brakes

A vehicle’s brakes are its most important safety feature. While checking brake pads and discs usually requires some technical knowledge, you can observe any changes in your brake’s performance.

If you notice any squeaking or grinding sounds, or if your vehicle pulls to one side when braking, it’s likely time for a brake check or service.

Inspecting the Belts and Hoses

Belts and hoses play a crucial role in your vehicle’s operation. Inspect these for any signs of wear, such as cracks or fraying on belts, and bulging or leaks on hoses. If they appear worn, it might be time for a replacement.

Checking the Windscreen and Wipers

Your windscreen provides a clear view of the road ahead, and it’s critical that it’s clean and in good condition.

Windscreen wipers also play a vital role in maintaining visibility during rainy weather, so they should be in top shape too.

Inspecting the Windscreen

Look over your windscreen for any chips, cracks, or damage. Even small chips can turn into large cracks, which can affect visibility and the overall integrity of the windscreen.

If you notice any damage, it’s best to have it repaired promptly.

Checking the Wipers

Windscreen wipers should be replaced if they’re not clearing the windscreen effectively, making a squeaking sound, or appearing worn or damaged.

A good rule of thumb is to replace them every six months to a year, depending on usage and weather conditions.

Understanding Your Vehicle’s Air Filter

The air filter prevents dust and other particles from entering your engine, helping to maintain its overall health.

While checking the air filter typically involves removing it from the car, you can usually see if it’s excessively dirty or dusty. If it is, it’s likely time for a replacement.

Keeping Your Car Clean

Regularly washing and cleaning your car can help maintain its appearance, prevent rust, and provide the opportunity to notice any new dents, scratches, or damage.

Don’t forget about the interior, either. Regularly vacuum and clean surfaces to keep them looking and smelling fresh.

Maintaining the Interior

From the seats to the dashboard, interior maintenance can keep your vehicle comfortable and pleasant.

Clean the seats according to their material (leather or fabric), wipe down the dashboard and other surfaces, and keep your windows clean for optimal visibility.

Regularly cleaning the interior can also prevent long-term damage, such as stains or odours that become difficult to remove.

Regular Servicing and When to Visit a Professional

Despite best efforts with regular home maintenance, there are some tasks that require the expertise of a professional.

Complex electrical issues, deeper engine troubles, and suspension problems are just a few examples.

Regular servicing by a professional can ensure that these deeper issues are caught early and addressed properly. Consult your vehicle’s manual for the recommended servicing schedule.

Understanding Australia-Specific Car Maintenance Requirements

In Australia, there are some unique factors that can affect your vehicle’s maintenance needs. These include local environmental factors, legal requirements, and the condition of the roads.
