Driven by the engine crankshaft, a belt/pulley system runs such items as the AC compressor, alternator, and power steering pump. Previously, the "V" profile was the universal belt design, but more modern vehicles use the flat "ribbed" design, often referred to as a serpentine belt.

Some highly sophisticated, modern vehicles have eliminated all belts by providing engine-driven internal shafts. Cooling fans, with few exceptions, are now run by compact electric motors.
