What is the role of accessory drive belts in engine and accessory operation on Ford F-250?

Accessory drive belts, also known as fan belts or V-belts, play a crucial role in the functioning of an engine and its accessories. Maintenance of their condition and tension is important to avoid issues of wear on bearings, noise, and belt failure. Belts lose their rigidity with time, therefore requiring regular checks and adjustments. It is necessary to inspect for cracks, glazing, fraying, or separation. Use the "rule of thumb" or gauge to measure tension. To adjust, move the bracket of the belt-driven accessory. Belt-tensioned devices rely on tensioners. Worn-out belts can be identified by examining wear indicator marks. While replacing them, slide off old belts and fit them into pulley grooves correctly.
