Glossary of Auto Terms

DriverSide's Car Dictionary has the most comprehensive definitions of automotive terms. This auto glossary can help you decipher what your mechanic is fixing and what the purpose or function of the particular auto part or accessory is for. We have taken the mystery out of automotive service jargon, so that you don't have to.


Fuel Filter

Usually hard to find in the engine bay, and about the size of a can of your favorite cola, the fuel filter's job is to--you guessed it, filter the fuel, removing dirt, grit, and other nasty stuff that could clog your other parts of your fuel system. These should be changed per manufacturer recommendation, and while doing this jod yourself isn't difficult, anytime you mess with fuel system components, the margin for error is much smaller. When things get hot, fuel is a dangerous thing.
