How to service your own car

Are you tired of spending time at the auto repair shop whenever your car needs service? Well, fret no more! This guide will show you how to service your vehicle like a pro. You will learn how to save, develop a deeper understanding of your vehicle and gain the satisfaction of a job well done. So, grab your tools, and let's dive into the world of DIY car maintenance!

Pre-Service Preparation

Before beginning the maintenance tasks, pre-service preparation ensures a smooth and successful DIY session. Here's what you need to do:

Gathering the necessary parts and supplies

Check your car owner's manual or consult an auto parts store to determine the specific parts and supplies you'll need for your car's make and model. This may include engine oil, air filters, spark plugs, coolant, and more.

Understanding the owner's manual

The owner's manual is your car's bible. It contains valuable information about recommended maintenance schedules, fluid capacities, and step-by-step instructions for various tasks. Familiarise yourself with it before starting any maintenance work.

Checking warranty and service history

If your car is still under warranty, performing specific maintenance tasks yourself could void the warranty. Check your warranty documentation or consult the manufacturer to determine which tasks can be done without voiding the warranty. Also, keep a record of your DIY maintenance activities for future reference.

Essential Car Maintenance Tasks

Now, let's move on to the car maintenance tasks you can tackle yourself. Remember, safety comes first! Feel free to seek professional assistance if you need clarification on any step.

Checking and topping up fluid levels

Engine oil

Start by locating the oil dipstick, pulling it out, and wiping it clean. Reinsert and pull it out to check the engine oil level. If it's below the recommended level, add the appropriate oil by removing the oil filler cap.

Coolant

Check the coolant level when the engine is cool. Locate the coolant reservoir, typically marked with "max" and "min" levels. If the coolant level is still low, add a 50/50 mixture of the coolant and water to the reservoir.

Brake fluid

Locate the brake fluid reservoir, usually near the firewall. Check the fluid level and ensure it falls within the recommended range. If needed, add brake fluid of the correct type.

Power steering fluid

Refer to the owner's manual to identify the power steering fluid reservoir. Check the fluid level and top it up if necessary.

Washer fluid

Inspect the washer fluid reservoir and ensure it's filled with a suitable washer fluid mixture. Refill if needed to maintain clear visibility while driving.

Inspecting and replacing filters

Air filter

Locate the air filter housing, which is usually a black plastic box near the engine. Remove the filter cover and inspect the air filter. If it is clogged, replace it with a new one.

Oil filter

Position an oil drain pan beneath the oil filter and use an oil filter wrench to remove the old filter. Before installing a new filter, apply a thin layer of oil to the rubber gasket. Screw on the new filter hand-tight.

Fuel filter

Fuel filters can be located along the fuel line, either under the car or in the engine bay. Consult your owner's or repair manual to locate and replace the fuel filter as needed.

Cabin air filter

A car's cabin air filter is usually behind the glove compartment. Remove the glove compartment and replace the filter if it's dirty or clogged, ensuring proper airflow into the cabin.

Checking and replacing spark plugs

Inspecting spark plugs

Remove each spark plug wire and use a spark plug socket wrench to remove the spark plug. Examine the electrode and the insulator for signs of wear or fouling. Replace any damaged or worn-out spark plugs.

Installing new spark plugs

Apply a tiny amount of anti-seize compound to the spark plug threads. Carefully thread in the new spark plugs by hand, then use the spark plug socket wrench to tighten them to the manufacturer's specifications.

Battery maintenance

Clean battery corrosion from the terminals

Detach the cables (negative cable first) using a wrench. Scrub the battery terminals with a wire brush and a combination of water and baking soda. Rinse with clean water, dry the terminals, and reattach the battery cables (positive cable first).

Checking battery voltage

Use a multimeter to check the battery voltage. Consider recharging or replacing the car battery if it's below the recommended level.

Replacing the battery

If the battery is old or not holding a charge, remove it by loosening the battery hold-down clamp and disconnecting the cables. Install the new battery, reconnect the cables, and secure the hold-down clamp.

Tyre maintenance

Checking tyre pressure

Use a pressure gauge to check the pressure in the tyres, including the spare. Adjust the pressure to the manufacturer's recommended PSI by inflating or deflating the tyres.

Rotating tyres

Refer to your owner's manual for the recommended tyre rotation pattern. Use a jack to lift the vehicle, remove the tyres, and reinstall them in the appropriate positions.

Inspecting tyre tread

Check the tyre tread depth by inserting a coin into the groove. If you can locate all of coin's head, it's time to replace the tyres.

Wheel alignment

If you notice uneven tyre wear or your car tends to pull to one side, it may require a wheel alignment. Consult a professional for this task.

Advanced Car Maintenance Tasks

If you're feeling confident and want to tackle more advanced maintenance tasks, here are a few you can consider:

Replacing brake pads and rotors

Signs of worn brake pads and rotors

Squeaking or grinding noises, reduced braking performance or a pulsating brake pedal are signs that your brake pads and rotors need replacing.

Removing and installing new brake pads

Secure the car with jack stands, remove the wheels, and unbolt the brake calliper. Replace the old brake pads and reassemble the components following the proper torque specifications.

Resurfacing or replacing brake rotors

Inspect the brake rotors for signs of wear or damage. If they are still within the specified thickness, have them resurfaced. If not, replace them with new ones.

Changing transmission fluid

Importance of regular transmission fluid change

Transmission fluid cools and lubricates the components. Frequent fluid changes can extend the life of your transmission.

Draining and replacing transmission fluid

Locate the transmission fluid pan, remove it, and drain the old fluid into a drain pan. Replace the gasket or filter if necessary. Refill the transmission with the appropriate fluid using a funnel.

Checking transmission fluid level

Refer to your owner's manual for the correct procedure to check transmission fluid levels. This may involve running the engine, shifting gears, and using the dipstick.

Changing the serpentine belt

Signs of a worn serpentine belt

Cracks, fraying, or squealing noises coming from the belt are indications that it needs replacing.

Removing and installing a new serpentine belt

Locate the belt tensioner, release the tension, and remove the old belt. Route the new belt following the diagram in your owner's manual, and release the tensioner to ensure proper belt tension.

Replacing the fuel pump

Signs of a failing fuel pump

Stalling, sputtering, or difficulty starting the engine could be symptoms of a failing fuel pump.

Removing and installing a new fuel pump

Access the fuel pump by removing the fuel tank or accessing it through an access panel. Disconnect the electrical connections and fuel lines, remove the fuel pump, and install the new one, following the manufacturer's instructions.

Troubleshooting Common Issues

Sometimes, car troubles arise that go beyond routine maintenance. Here are some common issues and the appropriate troubleshooting tips:

Identifying and addressing fluid leaks

Inspect the fluid leak's colour, consistency, and location to determine its source. Consult your owner's manual or seek professional help to fix the underlying issue.

Diagnosing engine performance problems

Listen for strange noises, monitor warning lights, and pay attention to changes in performance. Use a code reader/scanner to retrieve diagnostic trouble codes (DTCs), consult relevant repair manuals, or seek professional assistance.

Dealing with electrical issues

Check fuses and relays for any signs of damage or failure. If you're comfortable with electrical work, use a multimeter to test connections and troubleshoot the issue. Otherwise, consult an expert.
