The positive crankcase (PCV) ventilation valve is a one-way valve in a car's pollution control equipment. It ensures that gases are continually evacuated from the engine.

Power steering fluid is an oil formulated for use in power steering systems; it reduces the effort required to steer a vehicle. The power steering system uses a pump driven by the engine to generate pressure by compressing the fluid.

The engine generates heat when it is running; this heat must be removed to prevent damage to the engine. Coolant circulates throughout the engine and absorbs this heat.

An engine has two radiator hoses: lower and upper. The lower hose brings coolant (a mixture of water and antifreeze) that has been cooled in the radiator to the engine, where it circulates and absorbs heat.

By harnessing the power of the battery, the starter motor powers the engine to "turn over" and start when the driver turns the ignition switch. The starter motor also enables the driver to restart the engine once it has been switched off.

The steering wheel is attached to the steering gearbox by the steering shaft. As the driver moves the steering wheel, the steering gearbox, through a series of linkages, steers by pushing or pulling the front wheels of the vehicle.

The steering wheel is attached to the steering rack by the steering shaft. When the steering wheel is turned, the steering rack interprets the directional input and pushes or pulls the front wheels in the desired direction.

Suspension coil springs support the weight of the vehicle and determine the height at which it sits on the road. The springs allow the suspension system to move and adapt to changing road irregularities; they are under extreme pressure.

Shock absorbers dampen the shock the suspension absorbs when the vehicle is driven over an uneven road surface. There is a shock absorber at each wheel.
