Air filter:
A device that filters incoming air fed to the engine.

Cabin air filter:
A filtering system that meters out pollen, road dust and other particles before they can reach the passenger cabin.

Engine oil:
A substance that lubricates and cools the moving parts of the engine and reduces corrosion and the formation of rust.

Oil filter:
A cartridge-filled canister placed in an engine's lubricating system to strain dirt and abrasive materials out of the oil.

Air filter:

Brake lines, hoses & connections:
Tubes and their connections that carry brake fluid between the various components in a vehicle's brake system.

Brakes:
A vehicle's stopping mechanism comprised of a pedal connected to a hydraulic master cylinder that can actuate clamping and/or expanding devices at all four wheels that slow or stop a vehicle's rolling motion. Also used to refer to the brake system's most frequently replaced parts, brake pads and/or brake shoes.

Cabin air filter:
A filtering system that meters out pollen, road dust and other particles before they can reach the passenger cabin.

Drive belt(s):

Drive shaft:
A sturdy metal tube with universal joints on either end that connects the engine to a differential on a rear-wheel or four-wheel drive vehicle.

Engine oil:
A substance that lubricates and cools the moving parts of the engine and reduces corrosion and the formation of rust.

Exhaust system:
A system of tubing that routes exhaust gases from the exhaust manifold to the rear of the car and into the air. The exhaust system includes catalytic converters and mufflers that help reduce air and noise pollution generated by an engine.

Fluid levels:
The amount of liquid in reservoirs and sumps accessible from the topside of the vehicle: engine coolant, automatic transmission fluid, windshield washer fluid, power steering fluid, brake and/or clutch fluid, and engine oil.

Fuel lines, hoses & connections:
The tubing and connections that carry fuel throughout a vehicle.

Oil filter:
A cartridge-filled canister placed in an engine's lubricating system to strain dirt and abrasive materials out of the oil.

Parking brake:
The mechanical brake connected by cables to either a ratcheting hand lever or foot pedal used to hold or apply a vehicle's rear and sometimes front brakes while left unattended or under conditions of hydraulic circuit failure. Sometimes referred to as the emergency brake.

Suspension:
The assemblage of joints, links and other components between a vehicle and its wheels. The suspension in concert with the wheels and tires is largely responsible for a given vehicle's ride and handling characteristics

Tie rod ends, steering gearbox & boots:
Tie rod ends are lubricated ball and socket type joints between the wheel spindles and the steering linkage. The steering gearbox is on the controlled end of the linkage and at the base of the steering shaft. Boots are rubber seals that contain lubricant at any moving joints.

Wheels & tires:
A circular frame of hard material that may be solid or partly solid, is capable of turning on an axle, and holds the rubber cushion that contains compressed air.
