About This Quiz
Do you know how many different models of cars there are in the world? There are at least 75 different manufacturers out there and between them, they have produced over 1,700 different models. And that's how we've gotten to the point we're at today with over 1 billion cars on the road around the world. That's a lot of engines, a lot of brake systems, a lot of transmissions and a lot of flat tires. Someone needs to take care of all of that and mechanics are the ones who step up to the plate. But with so many models, manufacturers and malfunctions it takes a lot of tools to get it all right. You need engine cranes to yank those big blocks out, you need spark testers to check for current, you need an OBD2 scanner to figure out all those complicated dash error lights. And that's just a few of the dozens of tools at a mechanic's disposal.
You don't have to be a mechanic to know all the tools at a mechanic's disposal but it sure would help. If you think you can ID everything you might find in a shop, take the quiz and show us your stuff!

When you need more grip than a wrench can offer, or you're in a hard-to-reach place, which of these will do the trick?
A set of good quality sockets will get you that extra bit of torque you need to get even the most difficult of nuts and bolts. The idea behind the socket wrench isn't particularly new and these things have existed for several hundred years. Clock-winding keys from the Middle Ages were essentially socket wrenches.

Do you know the name of this super common tool that our friends in England call a spanner?
It would be hard to find a more important tool in a mechanic's repertoire than a good old-fashioned wrench. A good quality wrench won't just be made of steel, it'll be something like a chromium-vanadium steel alloy so it can stand up to some pressure.

Do you know which of these simple-but-remarkably-useful tools likely dates back to about 3000 B.C?
Pliers can come in a number of forms but for the most part, all you need are handles on a pivot with some kind of teeth on the other side. They're handy for holding, cutting, loosening, and even bending metal.

This tool is basically the mechanic's equivalent of a pencil. Do you know what it's called?
Sometimes when you're working with metal parts, you need to mark a measurement or where you need to make a cut but a pencil or a pen obviously won't work. A metal scribing tool works exactly like a pencil but it cuts the line into the metal rather than simply leaving a mark on the surface.

Sometimes the best way to dislodge a stuck rotor is with which one of these tools?
A hammer has more of a reputation as a carpenter's tool but it's 100% necessary in a garage setting for those times when something is so corroded, worn, or warped that it needs less finesse and more brute force like getting brake calipers and pads loose, or stuck rotors.

Which of these tools is perfect for delicate work, like separating wires and electrical connectors?
A pick and hook set may look like some rugged dental tools but they're great for precision work in a car. The tiny tools can remove O-rings, separate tightly attached electrical components, pry wires apart, and snag fallen washers or other tiny pieces you can't reach with your fingers.

Which of these tools is a mechanic likely to grab if a car is banged up and they need to pry something free, like a side panel?

Do you know which of these handy tools makes it easier to see into poorly lit places?

When you can't get a nut to come off no matter how hard you try, which of these tools is your last resort?
A nut splitter works by forcing a chisel tip into the flat side of a nut and, as you crank the handle, it embeds itself into the metal until the nut splits open. This will remove a stuck nut but not damage the threads underneath.

You can diagnose weird noises in a car with which of the tools?
Everyone has had a moment when their car was making a new and mysterious sound.

When you need a precise amount of torque which of these tools will help?
When you're in a hurry you might just want to tighten every bolt as tight as humanly possible, but that's not actually the right way to do things. Every bolt on a car actually has a factory-recommended amount of torque that should be applied and especially when you're dealing with lugnuts you want to keep that in mind. A digital torque adapter on a ratchet ensures the exact right amount of torque and no more.
