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!

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.

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.

If you want to get a look into someplace obscure and secluded inside a vehicle which of these tools has your back?

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.

When you want to diagnose an electrical issue which of these is the best choice?

A voltmeter is useful for dealing with a car's electrical system if something isn't working right and you need to find out where the short might be. The earliest voltmeters date back to the 1820s when Andre Ampere used one to measure a current.

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.

When you can't get a nut to come off no matter how hard you try, which of these tools is your last resort?

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.

A digital torque adapter on a ratchet ensures the exact right amount of torque and no more.

Everyone has had a moment when their car was making a new and mysterious sound.
