Service campaign CB778-1

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

Precedent C-600 units in the range listed above need an adapter fitting (P/N 513762) installed at the oil pressure sensor to prevent an engine oil leak. The oil pressure sensor must be removed, adapter fitting 513762 installed, then the original oil pressure sensor reinstalled. See the procedure on page 2 and 3 of this bulletin.

The document

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.

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