Tools for the up and coming auto mechanic.

motor, machine, mechanical

Obviously if you are serious about being In the automotive repair business you need to start investing in some tools.

A question asked a lot is, “what tools should I get to start out?” Hopefully I can get you started on your way with this quick list.

You should look at your tool arsenal as a investment that will bring returns, if you put in the work.

Where to start?

Cool, you just got out of tech school and you landed a job at an established shop. This is great! Now the next question is how do you start building up your tools.

Maybe you are heading to tech school, either way you need tools.

First of all tools are not cheap, a typical wrench set from Snap-on or Matco can be three or four hundred bucks easy, and I’m talking 8mm to 19mm. Although very expensive these tools are bought once in your life, they are top line tools.

If you are serious about this business, you need quality tools. I know the old saying “a wrench is a wrench” but this is not always the case. Take for instance a 7/8 open end wrench, one craftsman and one Snap-on.

Let’s say we are performing an alignment and we are trying to break a seized tie rod nut loose. If you use the open end of the craftsman wrench, you will see that at a certain point the torque will cause the end to open up and… bam….. rounded nut and possibly busted knuckles.

Now for the Snap-on, if you apply the same torque the open end will not spread open. The steel will snap before it stretches. Part of the reason for the huge price difference is the quality of the steel.

A cheap wrench will bend, a good one will snap before it bends. Investing in quality from the start ensures you have what you need to succeed in this business for life.

One thing I also want to touch on. I do not recommend going on the Snap-on truck and spending thousands of dollars on a new tool box and every tool snappy will let you put on your truck account.

Trust Scoot on this, they come around every week. Handing over 50 bucks plus every week starts to suck after a while.

I’m not saying you need all Snap-on or Matco tools, over time you will learn where to go cheaper, and where you need top notch.

Here is the list of tools you can’t go wrong with….

Let’s start with wrenches

I would start with a standard and metric set. Metric would include 6mm to 21 mm and standard would be 1/4 to 15/16 . Keep in mind this is a starter set, you will be needing much more over time. Some flex head ratchet wrenches would be great too.

You will need a good set of metric and standard allen wrenches, preferably with a ball end. A couple of larger wrenches are good to have, anywhere from 1” to 1 1/4.” Grab a pipe wrench if you will be doing any alignments for moving tie rods.

Stubby wrenches are great to have when you need to get into a tight area, also grab a large and small oil filter wrench. You will find over time your wrench drawer will evolve as you grow as a technician.

It’s not a race, this takes time. A good rule to follow is , if you are borrowing basic tools more than twice, it’s time to buy one. Use the veteran techs as a baseline. Make a list and pick away at it slowly, remember, if you are buying good tools they never drop in value.


Ok next drawer, pliers. Start here with a typical set that is usually on the truck, standard pliers, side cutters, long needle nose, long angle needle nose, and regular needle nose.

Channel locks. Small, medium, and large are a must. Vise grips as well, any variety that seems useful, I suggest staying with original brand vise grips. We also need some small mini pliers, fine needle nose for smaller tasks.

A good set of line crimping pliers are great too, these help with removing hoses etc while trying to minimize fluid loss. Get a good set of electrical pliers as well with a good stripper and crimper.

Electrical diagnostics

You need to know electrical systems and diagnostic strategies. I will cover this in depth soon, but for now let’s start with a good multimeter. The Fluke 88 multimeter is it.

I have had mine literally since I started, over 20 years ago. They are a little expensive, but this is one where I say, spend the money once. The meter has multiple features and is built to last. You can record data overnight to check draws and such. I will have a article just on this subject later on.

Another must is an inline circuit breaker to protect any circuit that you are jumping power too for testing purposes.

Ok here comes a little Scoot story. Many years ago I was working on a E30 BMW, long story short I was trying to see if the main relay was bad.

I jumped power from terminal 30 (constant power) to what was supposed to be the ecu power………well when you look at the relay it’s confusing sometimes as to what terminal is correct, guess what! I jumped it with no breaker and watched the harness burn up all the way to the ecu.

The breaker would have popped and saved me a bit of work, get one.

Get some good jumper leads, and a good test light. For the test light you can go a little cheaper, such as this OTC model

The second major tool besides the Fluke meter is a power probe. This is another must, it allows you to check for powers and grounds on circuits.

It also allows you to send power or ground to a specific circuit with just a toggle switch. These are critical for electrical system diagnostics.


This one is more obvious but we will hit on it. We need Phillips and flatheads, small and large. It seems like you can never have enough screwdrivers and pliers. It’s just one of those things. Make sure you get different lengths as well.

Torx head and some plastic trim tools are also a must. Next get some pry bars, spend the money on the truck for the biggest pry bar they have, trust me you will use it. Get smaller ones as well, usually they are sold in a set, except for the huge one.

Sockets and ratchets

Again here is a drawer that you can never put enough in. Start with standard and metric, shallow and deep sockets. Get the same in impact rated as well, you need this in 1/4 drive, 3/8 drive, and 1/2 drive to start.

Ratchets come in all sorts of lengths and configurations, get a few flex heads and longer handles. As I said with the pry bar previously, buy the biggest 1/2 breaker bar they have.

Impact swivel sets are a must, 3/8 drive for sure, make sure to grab adapters, these step up or down drive sizes. We need torx and Allen sockets as well.

Really this drawer evolves with you, there are a million different sockets and swivels out there you will know what you need as you progress.

Hammers, punches, etc.

Get good ball peen hammers in a few sizes to compliment your hammer drawer. Definitely get a very small one as well. Mine is one of my favorite tools.

Do not use a carpenter’s hammer, the steel is different and may produce sparks when hitting certain metals. Find a good set of round punches in steel, also get at least one 1/2 diameter punch in brass. Brass does not produce sparks and has a much less chance of marring metals.

Add a seal puller and installer kit in this drawer as well. Finish with a mini sledge and some sharp chisels.

Now is a good time to talk about an engraver. I have had the privilege of always working with top notch guys, people I would give the key for my house to and not even batt an eyelash.

I’ve never had to worry about someone stealing tools in my shop, but everyone’s situation is different. Engravers are so cheap it’s just crazy not to have one.

Regardless of your situation these tools are expensive. Engrave your name in them! Good and deep. Remember this is an investment, no need trying to prove to some idiot that the hammer he found is your hammer and not his.

Air tools

Air tools are a staple item in any technician’s toolbox. You need a impact wrench 1/2 inch drive and 3/8, it needs to be good quality. Compliment this with 3/8 and 1/4 inch air ratchets.

As you progress in this field you will learn that time is money. It’s like drag racing, every second counts in one way or another, this is why your tools are so important.

Imagine a surgeon with a dull scalpel trying to perform surgery, or a surgeon that can’t find what he needs when he needs it. Not a good look.

You will also need a good die grinder, and air hammer. The air hammer is key , you can do so much with this it’s crazy. Make sure you get air hammer bits, and the arbor for the grinder. Blow guns are a must, short and long.

Definitely a digital air chuck and angle grinder.

Keep in mind the tool guys are usually really cool guys, bust their chops a little, have them give you a better price, or that air hammer bit for free when you buy the hammer. Just remember they need to make a living too. Don’t take it too far.

Battery powered tools

By far the best and most used tools in my box are the 1/4 and 3/8 inch battery powered ratchets, you can also get impacts and many other tools that are battery powered.

You also need good drop lights, whatever your preference, invest in good light.

Battery powered tools serve a great purpose. I would recommend starting with air powered first though, you need to develop a “feel” for torque that I believe comes better with air tools.

Always remember that battery powered tools can not be used in flammable situations. It can and will ignite vapors.

Other needed tools

  • Impact driver and bits
  • Brake piston retraction tool
  • Good quality C clamp
  • Slide hammer set
  • Tap and die set
  • Coolant pressure tester is an absolute must, this allows you to pressurize a cooling system to pinpoint leaks, make sure you get a top quality one with plenty of cap adapters
  • Fuel pressure gauge set
  • Hand vacuum pump, this allows you to check for leaking vacuum operated components.
  • Feeler gauge set
  • Torque wrenches, this is a big one especially if you are in the european arena. A 1/2 inch and 3/8 to start out. I suggest a 3/8 digital with angle torque, and a 1/2 inch click type. Eventually you want a 1/4 digital for valve body torques etc.

Of course there are a ton more things you will need over time, like I said earlier, you and your toolbox will evolve.

Which brings me to storage

You will need a tool box . There are a few options here. You can go with a cheaper model such as a husky or something from harbor freight. This may be a good option if you are starting out and not sure if you want to do this forever.

If you plan on staying in this field I suggest you bite the bullet and get into a Snap-on or Matco box. Depending on your needs these things are huge money but they are a life long purchase. I personally have two Matco boxes.

My Matco 6s

I have had Snap-on boxes as well, both are top quality. It’s really a matter of preference and what deal is rolling around. The good thing is they hold value well, when you want to step up you should get good trade-in money.

One last thing I want to touch on quick is organization.

This article is soon to come but the main idea is if you are going to invest in tools and take this business serious as a technician, your tool box should not be a jumbled pile of tools everywhere. If you want to be productive you need to find what you need when you need it.

Your tools should be cleaned and put away every night. If I showed you every one of the techs tool boxes in my place, they are organized perfectly to their tastes.

Top all of this off with a good roll Cart and you are starting off well.

I can go forever with this list, comment below if you would like me to touch on this more.

One last thing I would like to bring up.

Make sure you get good safety glasses, hearing protection, and gloves for certain tasks. I love cars, I love this business, it’s not the most gentle on the body. Protect the best tool, yourself.

Learn , succeed, and pass on knowledge.
