Thomas Built Buses Saf-T-Liner HDX Recall 16V325: Coolant hose may fail and leak hot coolant inside bus

NHTSA campaign 16V325, reported May 19, 2016, 94 vehicles potentially affected.

What this recall means for you

Certain school buses have a transmission retarder that can raise coolant system pressure enough to fatigue the heater hose. Over time the hose can fail prematurely, allowing hot coolant to leak inside the bus body.

Hot coolant spraying or pooling inside the passenger area creates a risk of burn injuries to students and other passengers. Owners should treat this as a safety issue and have the affected bus inspected promptly.

The repair is free at an authorized dealer, which will replace the heater hose. Owners will be notified by mail, and you can contact Daimler Trucks North America customer service at 1-800-547-0712 (recall reference FL-709). You can also check your vehicle identification number (VIN) for any open recalls.
