Recall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

13V633000

ENGINE AND ENGINE COOLING:ENGINE:DIESEL

Dec 11, 2012
6,296 units potentially affected
The defect: Daimler Trucks North America (DTNA) is recalling certain model year 2011 through 2013 Thomas Built school buses manufactured from March 2010 through July 2012, equipped with Cummins ISB6.7 diesel engines manufactured from February 16, 2010, through May 4, 2012, containing a fan pulley, part number 3914462. The subject fan pulley is part of the accessory drive system on the front of the engine. This system is used to drive such components as the refrigerant compressors, the radiator fan, and the engine water pump. The web of the pulley can fatigue over time, causing the pulley to fail.
The risk: If this occurs, the fan belt may lose engagement of the water pump, allowing the cooling system to overheat. This may result in exceeding temperature limits, potentially disabling the school bus. If the school 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.
The remedy: Cummins will notify owners of the recall. Repairs will be performed by Cummins authorized service facilities. A new fan drive pulley will be installed free of charge. The safety recall began on January 4, 2013. Owners may contact Cummins at 1-812-377-5000 or DTNA at 1-800-547-0712.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
