When the engine is running, high voltage created by the ignition coil travels to the ignition cap through the coil wire to the ignition rotor. As the ignition rotor turns in the distributor, the rotor distributes the spark by sending it in a synchronized order through the spark plug wires to the spark plug located in each of the engine's cylinders.

Power steering hoses carry high-pressure power steering fluid from the power steering pump to the power steering rack to reduce the effort required to steer a vehicle. Fluid returns from the power steering rack to the power steering reservoir by means of a low pressure return hose.

Heat produced in the engine causes internal engine components to expand and contract. As the engine heats up, proper valve clearance is essential for optimal performance.
