DESCRIPTION AND OPERATION

Drive Belts, Accessory

Ford vehicles are equipped with poly-V drive belts (8620). To ensure maximum belt life, replacement drive belts should be of the same type and specification as originally installed.

The drive belts (except for 7.5L generator belt) are tensioned by an automatic belt tensioner which maintains proper belt tension at all times. The 7.5L generator belt is not automatically tensioned and requires periodic tensioning.

Loose drive belts will result in slippage that may cause a noise complaint or improper accessory operation (generator (GEN) (10300) will not charge, etc.). Overly tight drive belts will place severe loads on accessory bearings and result in premature drive belt or accessory failure. Refer to the illustrations in this section for the belt routing of each particular engine (6007).
