About This Quiz

The world of automobiles has a specific lingo and jargon all its own. If you're really into car craft, you know what we're talking about. If not, every word "car people" use that you don't know is like a multi-pronged fork in the road. And you have no idea which road to take or where each will lead. Car jargon is part engineering, part cool, part muscle, part tech, but loads of fun (if you can get over feeling a little dense, at first). 

For those of you who think you know the ins and outs of "car speak," this quiz will test how well developed your car linguist muscles are.

For those who feel a little obtuse when it comes to "car speak," why don't you try this quiz? You'll increase your auto IQ, and you'll also be able to speak intelligently to your mechanic the next time they start speaking in auto-babble. 

Unlike an automobile engine, this quiz is not timed. However, if you're feeling a little Bobby Unser or Dale Earnhardt in your veins, by all means, pull out your smartphone, toggle to your best timer app, and time yourselves to the split second.

Without further ado, ladies and gentlemen ...

Start your engines!

What is a freeze plug, and what does it do?

Freeze plugs — also known as core plugs — are small metal plugs that are found in an engine block's channels that carry coolant. If the coolant somehow freezes, because it is too diluted or only water has been used, freeze plugs are supposed to "pop" out of their channel to allow the excess pressure of expanding frozen water to escape. In theory, this will prevent an engine block from cracking due to that excess pressure.

Camshaft is just another word for the crankshaft, right?

An engine may have one or more camshafts. These move the intake and exhaust valves open and closed to properly aerate the combustion chamber and allow exhaust gases to escape.


Well then, where are the 'C' pillars?

The "C" pillars are on either side of your vehicle's rear glass and hold it in place.


In which vehicle system would you find an intercooler?

An intercooler would be found as part of the turbocharging system. It cools the air fed by the turbo, increasing the density of the air, and therefore the amount of air fed to the engine.
