How it all fits together?
The automobile has been around for more than a hundred years. It has evolved from gas buggies built in the late 1800s by Daimler and Benz in Germany and by Henry Ford, Ransom Olds, and others in the United States to our present day automobiles composed of more than 15,000 individual parts.
The early era cars were, at their time, complex machines that could only be enjoyed by the wealthy and repaired by dedicated and trained personnel known as mechanics. The traditional mechanic no longer exists today and has been replaced by highly trained personnel known as technicians.
Technicians often specialize in a specific area of the automobile such as driveability/ diagnostics, electrical / electronic systems, drivetrain, transmission, suspension/ steering / brakes, and body systems.
This specialisation has been made necessary by the many complex electronic and computer systems found in today’s cars. The relatively recent advent of electronic systems on the modern car has transformed it into a self-diagnosing and, to an extent, self-adjusting machine.
When you look under the hood of today’s automobile, the maze of tubes, wires, hoses, belts, and other parts may seem intimidating. Don’t let this first view alarm you. You can become more comfortable with what you’re looking at by becoming familiar with your vehicle.
