NHTSA's recall notice
As NHTSA's recall record states it for campaign 16V837000.
Defect description
Navistar, Inc. (Navistar) is recalling certain model year 2011-2016 IC Bus CE school buses manufactured November 3, 2009, to February 26, 2015, and 2012-2015 IC Bus BE school buses manufactured August 2, 2010, to September 15, 2014. The affected vehicles have a water shutoff valve, inside, forward of driver heater (feature code 48PPJ or 48PPP) that has a formed heater hose that over time, may fatigue and split resulting in hot engine coolant fluid leaking into the driver's foot area.
Safety consequence
If hot, pressurized coolant suddenly spills into the operator's foot area, there is an increased risk of a burn injury or a crash.
Manufacturer remedy
Navistar will notify owners, and dealers will replace the formed heater hose with a more robust one, free of charge. The recall began on January 4, 2017. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 16510.
