V-ribbed belts, also known as serpentine belts, are characterized by their unique design that features multiple longitudinal ribs on the belt's inner surface. These ribs grip the pulleys during rotation, enhancing the belt's ability to transfer torque efficiently. The cross-sectional shape of a V-ribbed belt resembles a series of V's, hence the name. Typically made from rubber or a composite material, these belts offer flexibility and resilience, making them suitable for a wide range of applications.

In contrast to the fan belt, the timing belt plays a more crucial role in the engine's operation. This belt is responsible for synchronizing the movement of the crankshaft and camshaft, ensuring that the engine's valves open and close at the correct intervals during each cylinder's intake and exhaust strokes. A timing belt is typically made of a reinforced rubber material and may include teeth or grooves to grip the camshaft and crankshaft securely.

A poly belt, also known as a serpentine belt, is a continuous loop that drives multiple peripheral devices in an automobile's engine. This type of belt is made from a durable, flexible rubber compound and features several grooves that run along its length, allowing it to grip the various pulleys it interacts with. The 7PK 612 model specifically denotes the belt's dimensions, with the 7PK indicating that it has seven ribs, and 612 referring to its length in millimeters, approximately 612 mm.
