engine serpentine belt

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.

A van belt is a looped flexible material, typically made from rubber or synthetic compounds, designed to transmit power between pulleys in a mechanical system. Its primary function is to facilitate the transfer of rotational motion from one component, such as a motor, to another, like a fan or a pump. The design of van belts varies depending on their specific application, with different shapes and sizes to accommodate diverse machinery requirements.
