Also fead belt failure poses a risk of engine compartment fire in vehicles equipped with automatic transmissions if it results in the transmission oil cooler hose rupture.
This is not a safety recall in accordance with federal regulation 573. However, it is deemed a safety improvement campaign by the Agency. The front end accessory drive (fead) serpentine drive belt can detach from the engine pulleys during certain engine operations. The diesel engine can cause the belts to stretch in excess of the tensioner capacity and the belt detaches from the pulleys.
