Reported risk: On certain school buses equipped with a Cummins ISB6.7 diesel engine, the engine fan pulley can fail. If this occurs, the belt would become detached from the water pump, which could cause the engine to overheat, potentially disabling the vehicle. If the bus is occupied when it becomes disabled, the occupants would need to exit the vehicle and be transferred to another vehicle, putting them at risk of injury. Correction: Cummins authorized service facilities will install an updated fan drive pulley.
