automotive fan belt

An endless flat drive belt is a continuous loop made from flexible materials, designed to transmit power between pulleys located at varying distances. Unlike traditional belts that often feature a textured surface or teeth for grip, flat belts rely on friction between the belt surface and the pulleys to facilitate movement. The endless feature indicates that the belt has no joints or seams, reducing the risk of wear and breakdown while ensuring a smooth operation.

The consequences of using the wrong fan belt size can be significant. A belt that is too short will struggle to fit around the pulleys, risking breakage and damaging components in the process. Conversely, a belt that is too long may slide off the pulleys entirely, leading to sudden and complete loss of power to the accessories it drives. This can be particularly dangerous while driving, as it can suddenly compromise power steering and even lead to engine overheating.
