Thomas Built Saf-T-Liner HDX School Bus: Heater and Defroster
Affects Thomas Built Saf-T-Liner HDX School Bus · 2014–2017 — about 21 vehicles.
The hazard
On certain school buses, the coolant line connected to the heater inside the bus may have been built with a fitting made out of incorrect material. This could restrict coolant flow and lead to premature failure of the elbow, causing a coolant leak inside the bus body. As a result, hot coolant may come in contact with the occupants of the vehicle and cause burn injuries. Correction: Dealers will replace buses built with a rubber elbow with a glass-filled nylon fitting.
