Especially when it comes to auto repair, basic knowledge of the services your auto mechanic recommends can mean the difference between the right repair and the cost of unnecessary work.

At Christian Brothers Automotive Arnold, we want our loyal customers protected, no matter which Arnold auto repair shop services their car. That’s why we’re providing a list of 5 essential automotive terms. With this information in hand, you’re sure to receive excellent customer service every time.

1. Dipstick

An ASE-certified technician pulls out your engine’s dipstick to visually inspect the level and quality of the motor oil. The professional will then determine whether your car is in need of an oil change.

2. Spark Plug

Your spark plugs ignite the engine’s fuel-air mixture. This ignition provides power to the engine. However, a burnt out spark plug will not ignite properly. This can overheat the ignition coils and may cause premature ignition failure.

3. [Battery] Corrosion

Battery corrosion is caused by acid leaking inside the battery case. This corrosion creates resistance around the battery, keeping the electrical current from reaching the starter. If unresolved, you could be left stranded with a dead engine.

4. Brake Pad

As you press the brake pedal, you’re wearing the brake pads against the rotors. Over time, the brake pads wear thinner and thinner. When our specialists inspect your brake system, they make sure the brake pads have enough friction material to safely stop the car.

5. Timing Belt

The timing belt is responsible for turning the camshaft. The timing belt is made of reinforced rubber and covered in ridges on the underside. As it turns the camshaft, the camshaft opens and closes engine valves to let the fuel-air mixture in and let exhaust gasses out.
