What's wrong?
The intake air grid heater on 2007-2011 Fccc B2, Saf-T-Liner C2, and Hdx school buses is part of the engine air intake system. Its job is to warm incoming air before it reaches the engine, which helps these diesel engines start and stabilize after startup. It sits in the path of intake air, so it must handle heat and electrical load without breaking down.
On affected buses equipped with the specified MBE900 engines, the grid heater can reach excessive internal temperatures. That heat can damage the heater internally, leading it to short circuit and fail. Once the heater fails, the intake air heating function is no longer dependable.
There is no warning sign before failure. A driver or fleet technician should treat the recall as a part-specific electrical and engine intake problem, even if the bus appears to start and run normally.
