Official summary

This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that may have oil mixed in with the engine coolant. 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.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
