Cummins ISL9 to replace the ISC8.3l
For years, the ISC8.3 has been a staple of the bus market. Starting in 2013, Cummins is incorporating all of the lower ratings from the ISC8.3 into the ISL9, and is discontinuing the ISC8.3 platform. Bus operators moving up to the ISL9 will find that it has the same great reliability and durability as the ISC8.3, since 95 percent of the components from the ISC8.3 are identical to those of the larger-displacement ISL. Operators will also see better fuel economy from the ISL9 in 2013 versus their 2012 ISC8.3 engines.
Ratings for the 2013 ISL9 range from 260 hp (194 kW) with 720 lb-ft (976 N•m) of peak torque to 350 hp (261 kW) and 1000 lb-ft (1356 N•m) in school bus applications. Transit buses will have a choice of 280 hp (209 kW) with 900 lb-ft (1220 N•m) of peak torque or 330 hp (246 kW) with 1100 lb-ft (1491 N•m) of peak torque, while shuttle buses have a selection of seven ratings from 260 hp to 370 hp (194-276 kW) with 720 lb to 1250 lb-ft (976-1695 N•m) of peak torque.
The extra torque generated by the ISL9 will provide bus operators better response in stop-and-go traffic and on highway entrance ramps versus buses powered by the current ISC8.3 engine. If you have any questions about this change, please contact your Cummins representative.

NHTSA BLUE BIRD RECALL JAN. 2012
Came across this recall info. From Jan.
Brown coolant in the C7 has been a concern for years, maybe the recall will provide some assistance?
* Coolant in certain Blue Bird school buses equipped with Caterpillar C7 diesel engines, 7L, 6-cyllinder turbo and air-to-air aftercooled engines with 190 to 300 hp rating, built from Dec. 14, 2006 through Jan. 6, 2009 can degrade. This may cause the engine components to deteriorate prematurely possibly resulting in coolant leaks.
