Whether your car is taken to an auto repair shop in McDonough or Ellenwood, Fayetteville or Covington (or anywhere in between), knowledge of automotive jargon can save you money in the long run. With a working knowledge of fundamental repair terms, you can make the right choices and avoid paying for unnecessary repairs.

At Christian Brothers Automotive Eagle’s Landing in Stockbridge, Georgia, we want to protect our customers no matter where they receive service. That’s why we’ve compiled the 5 most essential car terms every driver should know and understand.

1. Dipstick

The ASE-certified technician will pull out your dipstick to visually check the level and quality of the liquid as well as determine whether you need an oil change (or to replace another fluid).

2. Spark Plug

When your key turns in the ignition, the spark plug ignites the fuel-air mixture and powers the engine. However, a burnt-out spark plug will not properly ignite. Likewise, a spark plug covered in water could flood the engine.

3. [Battery] Corrosion

If water sits on the outside casing, your battery can quickly corrode. Leaking acid and rust built up under the hood also causes corrosion. A corroded battery will not function properly and could lead to a dead engine.

4. Brake Pad

Over time, your brake pads wear out. When our ASE-certified professionals check your brake system, they’ll inspect the brake pads’ thickness. This ensures they’re the proper width to effectively (and safely) stop your car.

5. Timing Belt

The timing belt is covered in bumps, operates the camshaft, is usually made of reinforced rubber, and is responsible for opening and closing valves at the proper time. The camshaft is an essential moving component to any combustion engine.
