Service bulletin PIP5257

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.

Technician will need to inspect the oil cooler if equipped for possible leaking into the cooling system through the radiator. If no issue found replace the engine as well as all rubber coolant hoses.
