Accessory Drive: Notes
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
Ford vehicles are equipped with a Poly-V drive belt. To make sure of maximum belt life, newly installed drive belts must be of the same type and specification as originally installed.
The drive belt is tensioned by a spring-loaded tensioner that maintains correct belt tension at all times.
A loose drive belt will result in slippage, which can cause a noise complaint or incorrect accessory operation. An overly tight drive belt will place severe loads on accessory bearings and result in premature drive belt or accessory failure. Refer to the following illustrations for the belt routing.
