Car Maintenance Tools for Servicing Your Own Car
The CRAFTSMAN CMMT12034 mechanics tool set is our top pick as the foundation of any home garage. The TEKTON 24335 torque wrench is the tool most people are missing, and the NOCO Boost Plus GB40 is the one that saves a morning when a battery dies unexpectedly.
The CRAFTSMAN CMMT12034 mechanics tool set leads this roundup because it covers the sockets, ratchets and hex keys that almost every job starts with, in a case that keeps them findable. The TEKTON 24335 click torque wrench is the single most valuable addition after that, since wheel nuts and drain plugs both have specified torque figures for good reasons, and the NOCO Boost Plus GB40 earns its place by turning a dead battery from a wasted day into a five minute job.
Building a home car toolkit is trickier than it looks because the listings are full of enormous sets padded with tools nobody uses, while the genuinely important items, namely a calibrated torque wrench and properly rated stands, are sold separately. We compared socket and drive coverage, stated torque accuracy, load ratings on lifting equipment, diagnostic protocol coverage and storage design, then weighed those against what owners report about long term durability and which tools ended up doing the most work.
What matters most
Buy the safety equipment first The temptation is to spend everything on tools that do jobs and treat stands as an afterthought, which is backwards. A jack lifts a car, it does not hold one, and hydraulic seals fail without warning. Buy properly rated stands, use them on level concrete under the manufacturer’s designated jacking points, chock the wheels remaining on the ground, and never rely on a jack alone.
Torque figures exist for a reason Wheel nuts, brake caliper bolts, spark plugs and sump plugs all have specified torque values, and guessing produces either stripped threads or a fastener that works loose. A click type torque wrench in the common half inch drive covers most of what a home mechanic touches. Wind it back to the lowest setting after every use, because storing it under spring tension drifts the calibration.
Cover the drive sizes rather than the piece count Piece counts in tool set listings are inflated by sockets in sizes that never come up. What actually matters is having quarter inch drive for interior trim and small fasteners, three eighths for most engine bay work, and half inch for wheels and suspension, in both metric and imperial. A set with sensible coverage across those three beats a bigger set built around one drive.
Diagnostics changed home servicing A basic code reader costs less than one diagnostic appointment and tells you whether a warning light means a loose fuel cap or a failing sensor. Generic readers cover engine and emissions codes on any car built to the OBD II standard. They do not read ABS, airbag or transmission modules on most vehicles, so treat one as a triage tool rather than a substitute for a proper scan when a safety system warning appears.
What we recommend
CRAFTSMAN CMMT12034 Mechanics Tool Set
This is the set that makes every other job possible, covering quarter, three eighths and half inch drives with both metric and imperial sockets plus the ratchets and extensions to reach them. The 72 tooth ratchets need a smaller swing arc than older designs, which matters in a crowded engine bay. The blow moulded case is bulky but keeps everything visible so missing sockets get noticed straight away.
Pros
- Covers metric and imperial in three drive sizes
- Fine tooth ratchets work in tight spaces
- Case layout makes missing tools obvious
Cons
- Case is bulky to store on a shelf
- Includes some sizes you may never use
TEKTON 24335 Half Inch Drive Click Torque Wrench
Tekton’s click wrench covers the range most car work needs, which is wheel nuts, suspension bolts and drain plugs, and it gives a clear audible click rather than the vague thud cheap wrenches produce. The dual range scale is easy to read without a torch. Store it wound back to its lowest setting, since leaving a click wrench under tension is the fastest way to lose accuracy.
Pros
- Clear, unmistakable click at the set torque
- Range suits wheel nuts and suspension work
- Easy to read scale in poor light
Cons
- Needs winding back to zero after every use
- Half inch drive is too coarse for small fasteners
NOCO Boost Plus GB40 Jump Starter
A lithium jump pack removes the need to find a second car and a willing neighbour, and the GB40 has enough output for most petrol engines and smaller diesels. Reverse polarity protection means a moment of inattention with the clamps does not end in sparks. It holds charge for months, but check it a few times a year rather than assuming it is ready.
Pros
- Starts a car without needing a second vehicle
- Safety protection guards against clamp mistakes
- Doubles as a power bank and work light
Cons
- Output is marginal for large diesel engines
- Needs periodic recharging in storage
ANCEL AD310 OBD II Scanner
When the engine light comes on, this plugs into the diagnostic port and tells you the fault code before you book anything in, which often turns a worrying dashboard warning into a loose fuel cap. It reads and clears generic engine codes and shows live data and freeze frame information. It does not touch manufacturer specific systems like ABS or airbags, which is the limit of a basic scanner.
Pros
- Turns a warning light into an actual fault code
- No batteries or app pairing required
- Simple enough to hand to anyone in the family
Cons
- Does not read ABS, airbag or maker specific systems
- Small screen makes long code lists tedious
Pro-LifT F-767 Hydraulic Trolley Jack
A proper trolley jack lifts faster and more stably than the scissor jack in the boot, and this one has enough capacity for the average car and enough lift height for wheel and brake work. The wide steel base resists the tipping that makes cheap jacks alarming. It is a lifting tool only, so it always has to be paired with stands before anyone goes under the car.
Pros
- Far faster and steadier than a scissor jack
- Wide base resists tipping under load
- Lift height suits wheel and brake jobs
Cons
- Heavy to move around a garage
- Never safe to use without stands in place
Torin Big Red T43002A Jack Stands
Stands take the load once the jack has done the lifting, and this pair covers the height range most cars need with a ratchet bar and a lock pin. The steel construction is heavy in a reassuring way. Always place them on level concrete under a manufacturer specified jacking point, chock the wheels still on the ground, and shake the car before trusting it.
Pros
- Essential safety item at a modest outlay
- Ratchet bar plus pin gives a positive lock
- Height range covers most passenger cars
Cons
- Only as safe as the surface underneath them
- Ratchet teeth need checking for wear over time
Slime 40026 Pro Power Tire Inflator
Correct tyre pressure affects fuel use, handling and tyre life more than most owners realise, and a home inflator means checking it whenever you like rather than hunting for a working forecourt machine. This one runs from a car socket, has a preset shutoff and inflates a car tyre reasonably quickly. It is not built for continuous duty on large truck tyres.
Pros
- Set a pressure and it stops automatically
- Removes reliance on forecourt machines
- Compact enough to keep in the boot
Cons
- Slow on large truck or camper tyres
- Motor gets hot during back to back use

Good to know
What tools do I actually need to change my own oil?
A socket or spanner for the sump plug, an oil filter wrench sized for your filter, a drain pan, a funnel, a jack and stands if the car sits low, and a torque wrench for the plug. Gloves and a supply of rags round it out.
Is a torque wrench really necessary for wheel nuts?
Yes. Under tightened nuts can loosen in use and over tightening warps brake discs and stretches studs. Manufacturers publish a torque figure for every wheel, and a click wrench is the only practical way to hit it consistently.
Do I need both metric and imperial sockets?
If you only ever work on modern vehicles, metric covers almost everything. Imperial sizes still appear on older American vehicles, trailers, aftermarket parts and garden equipment, which is why most sets include both.
Can a jump starter damage my car’s electronics?
Modern lithium packs with reverse polarity and spark protection are designed to prevent that, and connecting them in the right order makes it very unlikely. Follow the sequence in the manual and avoid cheap packs without protection circuits.
How often should I check tyre pressure?
Monthly is a common recommendation, plus before any long trip and whenever temperatures swing sharply, since cold weather drops pressure noticeably. Check when the tyres are cold for an accurate reading.
What does a generic OBD II scanner not cover?
Manufacturer specific systems, usually meaning ABS, airbag, transmission and body control modules. A generic reader handles engine and emissions codes on any OBD II compliant vehicle, which covers most warning light situations but not all.
Are expensive tool brands worth it for home use?
For occasional use, mid range sets from established brands are the sensible middle ground. Professional grade tools earn their premium through daily abuse and warranty support, which rarely applies to a few jobs a year in a home garage.
What should I never attempt at home?
Anything involving airbag units, high voltage hybrid or electric systems, or air conditioning refrigerant, all of which need specific training and equipment. Brake and suspension work is within reach for careful DIY, but if you are unsure about a safety critical fastener, have it checked.
The bottom line
Start with the CRAFTSMAN CMMT12034 set, because almost every job begins with finding the right socket and ratchet. Add the TEKTON 24335 torque wrench next, since correct torque on wheels and drain plugs is the difference between a job done and a job redone. The NOCO Boost Plus GB40 then covers the one failure most likely to strand you, and stands should be bought before any work happens underneath the car.
