The PK belt fan belt is a type of V-belt characterized by its trapezoidal cross-sectional shape, which allows for better grip on pulleys and reduced slippage. The PK designation refers to its dimensional specifications, including width and thickness, which are designed to meet the needs of a variety of automotive applications. PK belts are often made from durable materials like rubber, reinforced with fibers to withstand the considerable stresses and strains they encounter during operation.

A serpentine belt is a long, flat belt made from durable rubber that winds around various pulleys within the engine compartment. It is characterized by its unique design, which allows it to loop around multiple components, thus minimizing the number of belts needed to operate essential systems. The term serpentine derives from its winding or serpentine shape, which is visually distinct compared to the older setup of multiple V-belts used in many vehicles prior to the late 20th century.
