There are various types of drive belts, including serpentine belts, timing belts, and v-belts, each serving different applications. Serpentine belts are used in many modern vehicles to drive multiple components, including the alternator and air conditioning. Timing belts play a critical role in synchronizing the engine's camshaft and crankshaft, making them essential in vehicles. V-belts are commonly found in older car engines and various machinery. The complexity and function of these belts can significantly impact their cost. For instance, timing belts are usually more expensive due to their crucial role in engine operation and often require additional labor for installation.

For instance, when the engine runs, it rotates the crankshaft, which in turn causes the drive belt to spin. This motion activates the accessories connected to the belt. Unlike older cars that used several different belts to connect individual accessories, most modern vehicles utilize a single serpentine belt, which is more efficient and easier to replace.
