Service bulletin A191346 2033491-

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

Supersedes Technical Service Bulletin Group 19 number 13-44 dated July 18, 2013. Customer may report coolant leaking from the engine area. The leak can be traced to the connection of the water pump and the hose leading to the heater core. The seal ring is not the cause of the leak.
