Service bulletin SB2023

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

Beginning April 22, 2026, all T-90 units will be shipped with a new exhaust tube clamp PN 940036. As Thermo King works through existing production inventory, the original clamp that is pre-installed on the exhaust tube must be removed and discarded, then replaced with the new clamp PN 940036 and torque clamp to 9.6 ft.lb.

The document

• NHTSA's copy of the document (PDF)

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
