Service bulletin 167-T1524-12

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TT-15-030 For trucks equipped with the burner system, certain environmental and unit applications have been found to cause unreliable operation of the system. Collected technical data indicates that decreasing the maintenance intervals can greatly improve system reliability. High idle, time, constant exhaust brake operation, stop and go traffic and PTO operation can be factors that reduce reliability. A general burner system cleaning and inspection are being recommended at 75K miles and the 150K service interval will stay the same. Two parts kits have been developed to include all the necessary parts for the 150K service and the added 75K service if it is determined that parts replacement is needed.
