ISSUE:

The Front End Accessory Drive (FEAD) belt may come off on some vehicles equipped with a 4.9L engine. This may be caused by minor pulley misalignment and FEAD belt vibrations.

ACTION:

Replace the idler pulley with a revised idler pulley which should reduce belt vibration and misalignment by shortening the span between the belt and pulley. Refer to the following text for details.

Install the Idler Service Kit (F6PZ-6K007-AA) per Instruction Sheet 7172, included in the kit.
