Sounds are everywhere, and you have two cool parts on your body that let you hear them all: your ears! Your ears are in charge of collecting sounds, processing them, and sending sound signals to your brain.
Still the classic, rear drive was basically the only drivetrain system for many years. A longitudinally mounted engine, with the transmission bolted directly to it, sends power via a driveshaft to a differential unit at the rear axle. The differential turns the power 90Â° and sends it to the rear wheels.
A drive belt drives the accessories installed on your engine such as the alternator, power steering pump, water pump and the air conditioner compressor. Most modern cars have one or two drive belts. Although it's made of a very durable rubber-based material, the drive belt still wears over time.
