Maintaining and repairing your own car can save you money, boost your confidence, and teach you more about how your vehicle works.
Whether you’re working on something as simple as an oil change or as complex as servicing or replacing the brake systems, the right tools are key. Using the right tools, you can perform your work smarter, safer, and better than would otherwise be possible.
If you’re ready to start building your home garage toolkit, here are six essential tools every DIY car repair enthusiast needs.
1. Socket Set and Ratchet Wrench
The first — and arguably most important — tool for any DIY mechanic is a quality socket set with a ratchet wrench. Most car parts are held together with bolts and nuts, and you’ll need a reliable way to remove and tighten them.
A well-equipped set should include the following sockets and ratchets:
- SAE and metric sockets (foreign and domestic vehicles)
- Shallow and deep sockets for different locations of bolts
- Two ratchets at a minimum (⅜-inch and ½-inch drives)
- Extensions and adapters for restricted areas
A ratchet wrench allows you to swing bolts in and out without having to pull off the socket each time — a time-saver. For even more convenience, spend a bit more cash on a swivel or flex-head ratchet that can reach around an engine into tight areas.
2. Hydraulic Jack and Jack Stands
Under your vehicle — for exhaust, suspension, or oil changes — safety is not a choice. A hydraulic floor jack and a set of heavy-duty jack stands are required.
Your vehicle is supported off the ground by the jack, and the weight is safely supported when lifted by the jack stands.
Never support the car while working beneath it with only a jack. Jacks fail, and even a slight fall can lead to serious injuries or worse. Always place jack stands under the car at the recommended lift points and ensure they are level on a hard surface.
For added convenience and assistance, use a low-profile hydraulic jack on a small car or sports car. Two or three-ton-rated ones will raise most cars and light trucks.
3. Torque Wrench
When tightening bolts, you need to get a torque wrench. Otherwise, what looks like a safe repair might turn into anything but that. A torque wrench is especially critical when reinstalling bolts, especially on safety equipment like wheels, engine parts, or brakes.
There is a factory-specified torque rating on every bolt, so it doesn’t get too loose or too tight. A torque wrench will allow you to apply the same amount of force in terms of foot-pounds (ft-lbs) or Newton-meters (Nm). Over-torqued bolts can destroy threads or components, and over-relaxed bolts may lead to total failure.
4. Set of Screwdrivers and Pliers
No workshop is complete without screwdrivers and pliers. Cars are, after all, teeming with small fasteners, clamps, and connectors that require precision tools to manipulate them properly.
Your set of screwdrivers must include the following:
- Flathead and Phillips-head tips in varying sizes
- Tips that are magnetic so that screws will not fall into crevices
- A stubby screwdriver to reach tight spaces, and a long-reach driver to reach deep into parts
When looking for pliers, a good starter set should include the following:
- Needle-nose pliers for tiny or confined areas
- Slip-joint pliers to grasp hoses or bolts
- Locking pliers (Vise-Grips) to grip stuck components or destroyed fasteners
- Cutting pliers to trim wire or zip ties
You can always add to your set of screwdrivers and pliers as you need and can afford them.
5. OBD-II Scanner
Vehicles depend on computers and sensors to manage performance and emissions.
An OBD-II scanner (On-Board Diagnostics) is your passport into the mind of the car. It’s inserted into the diagnostic port in the rear of the dash and interprets the fault codes that triggered the light to turn on.
With a scanner, you can diagnose the issue before handing it over to a mechanic, eliminate warning codes after fixing the issues, and get live readings of engine temperature, fuel trim, and oxygen sensor activity.
6. Oil Filter Wrench and Fluid Drain Pan
If you do drain your own oil — and it’s probably the most common DIY car activity — you’ll also need an oil filter wrench and a fluid drain pan.
Oil filter wrenches are available in various styles. Those include cap-style wrenches that fit a specific size of filter, universal fit band or strap wrenches, and chain wrenches for really tight filters in hard-to-reach places.
Build Your Garage, Build Your Skills
You don’t ever need to have a genuine professional garage to fix your car — just the proper tools and the will. With a nice socket set, lifting equipment, torque wrench, hand tools, OBD-II scan tool, and oil change tools, you’ll be ready to attempt most minor repairs. You might enjoy DIY car repair and maintenance so much that you get your credentials to do it professionally. Or, maybe you’ll fall in love with the trades as a whole and pursue an online certification to become an electrician or forklift operator.
While many people bring their vehicles to their mechanics, you can go against the grain and do at least some maintenance and repairs independently. The right tools will help.
