# Service bulletin FSB 255 025

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

Due to part number reduction, when replacing the turbocharger on MACK LEU and MRU vehicles with MP7 and MP8 engines the turbocharger compressor housing must be reoriented to align with the charge air cooler pipe flange. Also, for MP7 engine serial numberless than 573627, oil drain line \(part number 22097764\) and coolant return line \(part number 20951827\) must be installed. Refer to Function Group 255 for service information.
