Service bulletin ATC2182B

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 Account Team Coverage is being issued to address lube pump gasket leaks in certain X12 CM2350 X119B engines, when it's confirmed the lube pump gasket has in fact failed, or leaks are present resulting from an insufficient seal. The current gasket design may not be capable of sealing the gap at the front T-joints, where the Block, Lube Pump, and Oil Pan intersect.
