Official summary
Service Update. On certain vehicles, equipped with a 6.6L diesel engine (RPO L5P), the engine coolant may have become contaminated. Dealers are to inspect the radiator surge tank. If contamination is visible, dealers are to order the required parts and schedule the customer for another appointment to perform the repair.
Vehicles covered
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.
