Plain-English summary

Caterpillar Inc. is recalling certain C7 diesel engines, 7L, 6-cylinder, turbo and air-to-air aftercooled engines with 190-300 horsepower ratings. These engines were built from December 14, 2006, through January 6, 2009, and sold and installed as original equipment in certain Blue Bird school buses.

The cooling system coolant in this application can degrade, which may cause engine components to prematurely deteriorate. This deterioration can lead to coolant leaks. Loss of coolant can result in stranded vehicles, increasing the risk of a crash.

Caterpillar is working with Blue Bird to identify and notify owners of the recall campaign. The safety recall began on January 1, 2012. Owners may contact Caterpillar at 1-800-447-4986 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
