About This Quiz

While you might not consider yourself an automotive "expert," you know your way around under the hood. You know what makes them tick. Or wait — do you, really? This quiz has 48 essential car parts (and maybe a few extras) that most cars need to operate or at least perform reasonably well. 

Do you think you can identify an AC compressor from a blower motor at a glance? You may know what an axle shaft is and what it does, but can you readily identify one? Do you know the difference between brake rotors and calipers? The door lock actuator, which is used every time you enter and drive your car, is also considered one of the best safety features every new vehicle should have. But have you ever seen one before? Unless you've ever worked on a car, we're guessing you haven't. 

These are the parts that help your car run and keep you safe. How many do you think you can figure out from an image? Buckle up; this quiz is going to take you on a ride!

Crankshaft
n/a
Name this car part in the image.
Crankshaft
Kingpin
Idler arm
Battery
Correct Answer
Wrong Answer

A critical part of the engine, a crankshaft transforms the reciprocating (up and down) motion of the pistons into rotational motion. This action is transferred to the transmission and then the wheels, moving your car.

Crankshaft seal
