Before you can use a workshop manual effectively, you need the right tools for the job. You do not need a professional workshop full of equipment to do meaningful work on your car. A well-chosen set of basic tools will cover the majority of maintenance and repair tasks. This guide covers the essential tools every home mechanic should own, what to look for when buying, and what to add as you take on more advanced work.
The Foundation: Socket and Spanner Sets
A metric socket set is the single most-used tool in any home garage. Most vehicles sold in Australia, Japan, Europe, and Korea use metric fasteners exclusively. A 1/4-inch and 3/8-inch drive set covering 6 mm to 24 mm sockets will handle the vast majority of bolts you encounter. Add a 1/2-inch drive set with larger sockets (17 mm to 32 mm) for suspension and axle work. Six-point sockets are stronger than twelve-point and less likely to round off fasteners, so prioritise those for your main set.
A set of combination spanners (ring/open end) in the same metric range complements the sockets for situations where a ratchet cannot fit. These are essential for brake line fittings, alternator bolts, and anywhere access is tight.
Torque Wrench
A torque wrench is not optional for serious work. Wheel nuts, caliper bolts, cylinder head bolts, spark plugs, and drain plugs all have specific torque values listed in your workshop manual. A 3/8-inch drive torque wrench covering 10 to 80 Nm handles most engine and brake fasteners. A 1/2-inch drive wrench covering 40 to 200 Nm is needed for suspension bolts and wheel nuts. Click-type torque wrenches are the most common and reliable for home use.
Jack and Jack Stands
A hydraulic trolley jack (at least 2-tonne capacity for cars, 3-tonne for larger vehicles) and a pair of quality jack stands are essential for any work that requires getting under the vehicle. Never work under a vehicle supported only by a jack. Your workshop manual identifies the correct jacking points for your specific vehicle, which are reinforced sections of the chassis designed to take the weight safely.
Multimeter
A basic digital multimeter (around $30 to $80 AUD) is essential for electrical diagnostics. You will use it to test battery voltage, check alternator output, measure sensor resistance values, test fuses, and trace wiring faults. Your workshop manual provides the voltage and resistance specifications for every electrical component, but you need a multimeter to actually measure them.
OBD-II Scanner
A basic OBD-II code reader or Bluetooth adapter ($20 to $50 AUD) lets you read and clear diagnostic trouble codes, which is the starting point for any check engine light diagnosis. See our OBD-II codes guide for a full explanation of how these work and what the codes mean.
Screwdrivers, Pliers, and Specialty Tools
A set of Phillips and flat-blade screwdrivers in various sizes covers interior trim, electrical connectors, and hose clamps. Needle-nose pliers, standard pliers, and a set of locking pliers (vice grips) are used constantly. Add a set of hex (Allen) keys and Torx bits, as many modern vehicles use these for interior trim, brake callipers, and engine components.
As you take on more specific jobs, you will add specialty tools like a brake calliper piston tool, a ball joint separator, a bearing puller, or a spring compressor. Your workshop manual will identify any special tools required for a specific procedure before you start.
Consumables to Keep on Hand
Keep a supply of brake cleaner spray, penetrating oil (for seized bolts), thread locker (medium strength), copper-based brake grease, electrical contact cleaner, and a range of cable ties, split pins, and replacement hose clamps. Disposable nitrile gloves and a pack of clean rags are used on every single job.
The Most Important Tool: Your Workshop Manual
Every tool in your kit is only as useful as the information guiding how you use it. Your vehicle’s workshop manual tells you which size socket fits each bolt, what torque to set your wrench to, what voltage your multimeter should read, and what special tools you need before starting a job. Without it, you are guessing.
