# Service bulletin SS1034797

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

Service Solution for M2 108SD 114SD Coolant Level Sensor PN 06\-93316\-002. This bulletin was updated 1/28/2021 to reflect the removal of the backshell P/N 23\-13302\-633, as the added length of the backshell makes it difficult to route the harness around the lower mounting bolt of the surge tank.
