Service bulletin C2137A

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

This Campaign is being issued to address Variable Geometry Turbocharger Actuator failures on certain ISL9 CM2350 engines in Transit Bus applications. This document authorizes certified repair locations to replace the Variable Geometry Turbocharger Actuator and to install the appropriate vent lines. This is an update to a previously submitted communication.

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.

Components

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