Tooth belts are typically made of high-performance materials such as neoprene or polyurethane, reinforced with fibers like glass or aramid to enhance strength and durability. The primary characteristic that distinguishes tooth belts from traditional V-belts is the presence of teeth on the inner surface. These teeth engage with corresponding grooves on the pulleys, ensuring that there is no slippage during operation. The design allows for precise timing and synchronization between connected components, making tooth belts invaluable in applications where accuracy is critical.

One of the standout features of PK belts is their ability to drive various components like the alternator, water pump, power steering pump, and air conditioning compressor all at once. This multipurpose functionality drastically reduces the number of belts required in a vehicle, leading to a more compact and lighter engine design. This design not only saves weight but also improves fuel efficiency—a benefit that has become increasingly critical for both manufacturers and consumers today.

2. Serpentine Belt The serpentine belt, on the other hand, is responsible for driving multiple peripheral devices in the engine, including the alternator, power steering pump, water pump, and air conditioning compressor. This single continuous belt is an efficient innovation that replaced multiple smaller V-belts, reducing the overall complexity of the engine. A failure in the serpentine belt can lead to a loss of power steering or charging capabilities, making it a crucial component for everyday driving. Typically, serpentine belts need to be replaced every 50,000 to 100,000 miles, depending on wear and tear.
