The serpentine belt is a long, continuous belt that drives multiple peripheral devices in an automobile's engine. Unlike older vehicles that utilized multiple belts for different components, the serpentine design streamlines the operation by incorporating a single belt to drive the alternator, power steering pump, water pump, air conditioning compressor, and sometimes even the radiator fan. This simplified design not only reduces the overall weight of the engine but also minimizes the noise and vibration associated with multiple belts.

A timing belt is a toothed, rubber belt that connects the crankshaft to the camshaft in an engine. It is designed to transmit rotational motion and maintain the timing relationship between the crankshaft, which drives the pistons, and the camshaft, which operates the intake and exhaust valves. In most modern vehicles, the timing belt is situated behind various components under the engine cover, making it less visible but still crucial for engine operation.
