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.


Push Rods

Only used in non-overhead cam engines, pushrods are metal rods that go between the camshaft and the rocker arms. The push rods cause the valves to open and close via the rocker arms. These generally limit high-rpm performance, but have been used successfully in the Chevrolet Corvette and other otherwise high-technology vehicles for years.
