The primary function of the drive belt is to transfer power from the engine’s crankshaft to various accessories, enabling them to operate. 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.

A failing fan belt can lead to a number of issues. One of the most common signs of a worn-out fan belt is a squeaking or squealing noise when starting the engine or while driving. This sound indicates that the belt is slipping and may soon fail. In severe cases, a broken fan belt can cause a complete engine shut down as your vehicle's accessories lose power. Therefore, regular inspection of the fan belt for signs of wear or damage, such as cracks or fraying, is vital to prevent unexpected breakdowns.

The timing belt is a rubber toothed belt that connects the crankshaft to the camshaft(s). In engines with an interference design, the timing belt is even more critical, as it prevents the pistons from colliding with the open valves. When an engine is running, the crankshaft rotates the timing belt, which, in turn, drives the camshaft. This operation ensures that the engine’s valves open and close at the ideal moments during the intake and exhaust strokes.
