Service bulletin Plunger Valve

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

Findings have concluded that there were some plunger assemblies installed out of tolerance. The gasket could chaff or lodge in the valve housing set if not corrected. Mounting flange gaskets will be sent to the customer so the discharge valve can be opened to inspect the plunger valve.
