poly belt 5pk1100

Car engine belts are rubberized components that drive various accessories and systems in the engine, converting the rotational energy produced by the engine into a usable form for other parts. These belts are essential as they facilitate the functioning of crucial systems, including the alternator, water pump, air conditioning compressor, and power steering pump. A well-functioning engine belt ensures that these components receive the necessary power, maintaining the vehicle’s operational efficiency.

In a CVT system, the transmission belt operates between two pulleys that can change diameter. As the engine generates power, the primary pulley expands and contracts, causing the belt to move up and down its sides. This movement adjusts the gear ratio according to the vehicle's speed and engine load, allowing for optimal engine performance and efficiency at all times. The belt's ability to flex and adapt is what makes the CVT smooth and responsive, eliminating the shift shock commonly experienced in traditional transmissions.
