Thomas Built Buses recall: Engine and engine cooling
What is wrong
Daimler Trucks North America LLC (DTNA) is recalling certain model year 2014-2017 Thomas Built Buses Saf-T-Liner HDX school buses manufactured November 29, 2012, to February 4, 2016. These vehicles use a rubber elbow to connect a coolant line to a heater inside the bus. This elbow may restrict coolant flow and possibly fail as a result of the increased stress on the elbow.
What could happen
If the rubber elbow fails, hot coolant may leak inside the bus body increasing risk of injury to the passengers.
The fix
DTNA will notify owners, and dealers will replace the rubber elbow with a nylon fitting, free of charge. An interim notice was sent out to owners on July 6, 2016. The recall began on September 20, 2016. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-708.
